Compact Courses

Speaker: Prof. Georg Stadler • New York University • Romberg Visiting Scholar
Location: Mathematikon • Seminar Room 9, 4th floor • Im Neuenheimer Feld 205, 69120 Heidelberg
Registration: Please register here • Registration open until April 3, 2025
Organizer: HGS MathComp

ECTS: 2

This course is part of the HGS MathComp Romberg Program.

The course will consist of 90-minute theory sessions in the morning (10-12) and practical sessions on Tuesday and Thursday afternoon (1-2:30).

In systems with uncertain parameters or white noise forcing, one often focuses on low-order statistics such as means and variances. However, when rare/extreme events have severe consequences-such as hurricanes, energy grid blackouts, or building collapses-estimating tail probabilities becomes crucial. This mini-course will first discuss the challenges of rare event probability estimation. It will then introduce key methods for exploring tail probabilities, including importance sampling, subset simulation, and optimization-based techniques for identifying dominating points in rare event sets.

Prerequisites: Basic undergraduate Probability, Optimization and Analysis.

ECTS: 0.5

Collecting, processing and analyzing data are central activities for virtually every researcher. Topics like data sharing and data publication are becoming increasingly important. Nevertheless, many research projects lack a structured and well-organized data management. This course is meant to give a general, discipline-independent introduction into various topics central to an efficient management of research data with a special focus on questions related to data archiving and data sharing. Both are central aspects of good scientific practice. Archiving and long-term preservation of research data are prerequisites for the scrutiny of scientific results based on the analysis of this data. Data sharing on the other hand increases transparency of research results and enables possible re-usage of data for new research questions, in combination with additional data sets and in interdisciplinary contexts.

In particular, the course will cover the following topics:

Requirements on research data handling from universities, research funders and scientific journals
Short-term and long-term preservation: formats, metadata, documentation, standards
Open Research data, data publication and data citations: Where? How? Why and why not?
Creation of data management plans for research projects

Machine Learning is transforming science, especially the way we do research in medicine. It can analyze non-linear dependencies of structured clinical data, and it is starting to support in the huge amount of existing text and other unstructured information to extract useful information using recent techniques based on large language models. There is also an increasing amount of specific omics data for each patient, which makes it hard to manually inspect all the details. This is where multimodal data analysis comes in, which is the focus of this year's AI in Medicine workshop. Researchers from Sorbonne and Heidelberg will give keynote speeches to provide insight into their research field, which will fuel discussions.

Location: Mathematikon • Conference Room, Room 5/104, 5th Floor • Im Neuenheimer Feld 205 • 69120 Heidelberg
Registration: No registration required

ECTS: 1 for 5

The IWR Colloquium serves as a platform for the interdisciplinary dialogue which characterizes the field of scientific computing. Every semester, members of the IWR and its affiliated institutions as well as renowned international experts are invited to present their latest scientific results and discuss the upcoming challenges in the field of scientific computing.

The IWR Colloquium will be held as an in-person event at the Mathematikon. In addition it will be streamed via Zoom. For more information please visit the website of the colloquium.

To study the nonlinear properties of complex natural phenomena, the evolution of the quantity of interest can be often represented by systems of coupled nonlinear stochastic differential equations (SDEs). These SDEs typically contain several parameters which have to be chosen carefully to match the experimental data and to validate the effectiveness of the model. In the present paper the calibration of these parameters is described by nonlinear SDE-constrained optimization problems. In the optimize-before-discretize setting a rigorous analysis is carried out to ensure the existence of optimal solutions and to derive necessary first-order optimality conditions. For the numerical solution a Monte-Carlo method is applied using parallelization strategies to compensate for the high computational time. In the numerical examples an Ornstein-Uhlenbeck and a stochastic Prandtl-Tomlinson bath model are considered.

This is a joint work with Jan Bartsch and Robert Denk. The associated paper will appear in the Journal Applied Mathematics & Optimization.

The Unix Shell + Version Control with Git
[ more ...]

Compact Courses

ECTS: 0.5

This is a one day course. The first half of the day covers the basics of the Unix Shell, the second half covers Version Control with Git.

The latest information and a registration link are available on the course website.

This compact course is part of the course program of the Scientific Software Center (SSC) at Heidelberg University.

Prerequisites:

No prior knowledge by the participants is necessary to participate in this course and it is intended for all scientific audiences. Participants are required to bring their own laptops to work on during the course. Network access (e.g. through Eduroam) is recommended.

Summary:

The Unix shell is a powerful tool that allows people to do complex things with just a few keystrokes. More importantly, it helps them combine existing programs in new ways and automate repetitive tasks so they aren’t typing the same things over and over again. Use of the shell is fundamental to using a wide range of other powerful tools and computing resources. The course will include hands-on live coding sessions where participants exercise the learned commands on their own computers.

Version control is the lab notebook of the digital world: it is used to keep track of what was done and to collaborate with other people. Its use is the state of the art in software development projects of all scales. However, it is not limited to software: books, papers, small data sets, and anything that changes over time or needs to be shared can and should be stored in a version control system. The course will include hands-on live coding sessions where participants exercise the learned commands on their own computers.

Learning Objectives:

- Have a fundamental understanding of how and why to use the Unix Shell
- Be comfortable with handling files and directories using the command line
- Have experience with advanced usage of the shell e.g. loops, pipes, redirects etc.
- Know how to write their workflows as reusable shell scripts
- Understand the benefits of using version control
- Understand basic git terminology
- Have a good working knowledge of common tasks in Git
- See how Git repositories can help them to move towards practicing Open Science

Location: Mathematikon • Conference Room, Room 5/104, 5th Floor • Im Neuenheimer Feld 205 • 69120 Heidelberg
Registration: No registration required

ECTS: 1 for 5

In this talk, I will introduce Cut Finite Element Methods (CutFEM) for interface problems and present recent developments, such as mass conservation, within this class of unfitted finite element techniques. Finite Element Methods (FEM) are widely used to approximate solutions to partial differential equations (PDEs) in complex geometries, but they typically require conforming computational meshes. The goal of CutFEM is to allow interfaces or boundaries to intersect the computational mesh arbitrarily while preserving desirable properties of standard FEM. I will explain how CutFEM maintains accuracy and avoids ill-conditioning of linear systems, even with unfitted meshes. I will begin with stationary problems, and then present our approach for discretizing time-dependent PDEs in evolving domains, and demonstrate its application to simulations of surfactant dynamics in incompressible two-phase flow systems.

ECTS: 1

An 8h introduction to certified programming and formal mathematics for graduate students interested in the interaction between mathematics and computer science.

Course times on both days: 10:00 - 12:00 & 14:00 - 16:00

What is Lean?
Introduced by Leonardo de Moura in 2013, Lean is an open-source functional programming language that can be used as an interactive theorem prover. In this workshop, we will see it in action as a development environment for computer-assisted mathematics.

Course description
Producing certified, reliable code is crucial in software engineering. Taking it a step further, modern programming languages with strong type-checking capabilities can even be used to state theorems about abstract mathematical objects and verify the correctness of proofs.

In this workshop, we will explore the world of proof assistants and learn how to explain mathematics to a computer using Lean. The goal is to help participants develop new coding skills while becoming acquainted with formal methods on a larger scale.

Contents of the workshop
The course will consist of four 2-hour sessions, spread over two days. Each session will combine a lecture with hands-on computer practice. Please bring your laptop.

- Lecture 1: Basic Lean syntax
- Lecture 2: Tactics
- Lecture 3: Dependent types
- Lecture 4: Group project

Participants will be asked to work in pairs. The instructor will provide practice files for each session and no prior installation of Lean is required.

ECTS: 1

Academic posters are a useful communication method to present your PhD project, engage people in fruitful discussions and gain new input for your research. To suit that purpose, a poster needs to be carefully designed, both from the contents' side and the visual appearance. Starting with the content, we will extract the key messages from your projects. All the way from the research question at hand, to the results and finally to the discussion and open questions. Keeping the target audience in mind, we will determine what should be on the poster and how we can communicate it efficiently. With the aim in mind to reduce text to an absolute minimum, we will focus next on the visuals that should go on the poster. These can include photographs, maps, schematic drawings, diagrams or other data visualizations. Having determined the contents, we will address the graphic design both of the individual visuals as well as of the poster as a whole. You will learn how to use a grid and white space, choose colors, fonts and font sizes etc. to produce an aesthetically pleasing and effective poster.

During the workshop each participant will design his / her poster about his / her own PhD project. You need to bring text and figures (diagrams, charts, schematics, photos etc.) describing your project. Poster drafts are welcome as well.

This talk will be held as part of the IWR Scientific Computing Seminar.

The high dimensionality is a central challenge faced by many numerical methods for solving large-scale Bayesian inverse problems. In this talk, we will present some recent developments in the identification of low-dimensional subspaces that offer a viable path to alleviating this dimensionality barrier. Utilising concentration inequalities, we are able to identify the intrinsic subspaces from the solutions of certain eigenvalue problems and derive corresponding dimension-truncation error bounds. The resulting low-dimensional subspace enables the design of inference algorithms that can scale sub-linearly with the apparent dimensionality of the problem.

ECTS: 1 for 5

Dr. Nikhil Arora is a guest researcher in the AstroAI lab (Buck group), invited under the HGS MathComp guest program by PhD Fellow Anna Lena Schaible. Nik is a PostDoc from Queen’s University in Canada. He works on comparing simulations and observations of galaxies. Currently he is working on creating HI predictions from the simulation for the SKA telescope. For the stay, he will be working on providing observational constrains for the RUBIX pipeline, which is a virtual telescope software to create mock-observations.

Galaxy formation and evolution is a multi-scale, multi dimensional and multi-physics problem. While using modern high-resolution telescopes can offer us high-quality insights in galaxies, deciphering the physics of galaxy formation requires cosmological simulations which track the evolution over the history of the Universe. In this talk, I will describe the various ways to compare cosmological simulations with observations of galaxies. I will present a rich dataset of observed galaxies and present novel ways to constrain galaxy formation models. I will show that modern cosmological simulations reproduce various properties of observed galaxies however, fall short in matching the dynamical properties.

This event is part of the academic programme of the Heidelberg Graduate School for the Humanities and Social Sciences (HGGS).

As the issue of academic freedom is politically sensible in several countries this course is strictly confidential: No registration and no names will be required, the course is strictly in person (no hybrid and no online participation), no list of participants will be checked or provided and no recording will be allowed.

In times of globally growing pressure on universities the principle of academic freedom is fiercely debated within and outside academia. What does it mean? What is covered? What is not? Is it an institutional or a personal right? Where are its limits? What are the threats?

Surprisingly few academics have well-informed knowledge what academic freedom is and what it is not. Debates and actions are often driven by emotions and subjective feelings about a “proper university“ instead of proper knowledge.

In this course we will:

I. discuss the principle of academic freedom – its legal status and its formal applicability

II. learn to discern academic freedom from other civil liberties (e.g. open speech, freedom of opinion)

III. understand the complexity of taking action in the face of violations to academic freedom

IV. sharpen our awareness for threats to academic freedom in our own societies.

The course and discussions will be in English.

We expect engagement and interest – no marks will be given!

Robust Optimization Approaches for PDE-constrained Optimization under Uncertainty
[ more ...]

IWR Colloquium

Speaker: Prof. Stefan Ulbrich • Department of Mathematics, Technical University of Darmstadt
Location: Mathematikon • Conference Room, Room 5/104, 5th Floor • Im Neuenheimer Feld 205 • 69120 Heidelberg
Registration: No registration required

ECTS: 1 for 5

The consideration of uncertainty in optimization problems is an important aspect in many practical applications. In this talk we consider optimization problems with partial differential equation (PDE) constraints, where uncertainty occurs in parameters (for example material parameters, usage scenarios) as well as in the optimization variables (e.g. manufacturing tolerances). There exist several approaches to handle uncertainty in optimization, in particular stochastic optimization, probabilistic constraints and (distributionally) robust optimization.

We will focus on robust and distributionally robust optimization approaches for problems with expensive PDE-constraints. In robust optimization, relevant realizations of the uncertain variables are described by an uncertainty set and it is required that the optimization variables satisfy critical constraints for all realizations of the uncertain variables in the uncertainty set. In distributionally robust optimization one considers an ambiguity set of relevant distributions for uncertain parameters and requires that the constraints are satisfied in expectation for all distributions in the ambiguity set.

The resulting robust formulation is a semi-infinite optimization problem and can be written in a min-max form. We present various techniques how to approximate and reformulate the robust problem by using optimality conditions and duality theory in order to obtain a tractable problem. Depending on the approach, the reformulation contains conic constraints, complementarity conditions and conjugate functions. We will sketch suitable solution methods.

Moreover, we will illustrate, how adjoint techniques as well as model order reduction and error estimation can be used to solve these problems efficiently in the PDE constraint case.

We present several application examples, in particular the design optimization of electric machines under uncertainty.

Understanding and predicting maladaptive human behavior and cognition, which are pertinent to many psychiatric disorders, requires understanding their underlying dynamics and dynamical mechanisms. Modifying these behaviors requires control over their dynamics.

My group focuses on inferring the dynamics underlying human behavioral and neural time series, utilizing both process-driven and data-driven modeling approaches. Based on these methods, we develop mental health applications where dynamics are used to predict and control future system states, or to study their generative mechanisms. Our applications include: 1) Mobile apps that assess psychological ratings as proxies for mental health states, forecast changes over time, and use these forecasts to tailor mobile mental health exercises. 2) Web-based platforms in which we specifically tailor cognitive experimental paradigms to reliably assess complex decision-making. And 3) we develop and apply models for the reliable detection of neural dynamical systems features predictive of psychiatric dysfunction.

In this colloquium, I want to introduce to you the new RG and its members, along with current and future research directions.

Chaos and unpredictability are traditionally synonymous, yet large-scale statistical-learning methods have recently demonstrated surprising ability to forecast chaotic systems well beyond typical predictability horizons. I will describe my recent work evaluating forecasting methods on a large-scale dynamical systems dataset. At long forecast horizons, diverse methods—ranging from reservoir computers to neural ordinary differential equations—exhibit a universal tradeoff between inductive bias and forecast ability. In this regime, we find that classical properties like Lyapunov exponents fail to determine empirical predictability. Rather, forecast methods are limited by their ability to learn long-timescale slow manifolds associated with a system’s invariant measure. Our results inform a general view of complex dynamics as a generative process, with implications for how we construct and constrain time series models.

This course is part of the HGS MathComp Romberg Visiting Professor Program.

Waves, patterns, and other structures play a crucial role in applied mathematics. The study of their dynamic stability under perturbations is an important issue in our understanding of these structures. This theory lies at the interface between dynamical systems and functional analysis. The aim of these lectures is to present a general overview of the methods in this theory, some of its key aspects and its application to the question of stability of waves in dissipative systems.

This course aims at PhD students with a basic background of (functional) analysis, theory of partial differential equations in Hilbert spaces and dynamical systems (analysis of ODE).

The room for Monday is Seminar Room 11, the room for Tuesday and Wednesday is Seminar Room 10.

Syllabus:

- Motivation: coherent structures in PDE
- Stability theory for non-linear ODEs
- Asymptotic stability in dissipative systems
- Essential and point spectrum of a linear operator
- Semigroups and exponential stability
- Non-linear estimates and orbital stability

Location: Mathematikon • Room 5/104, 5th Floor • Im Neuenheimer Feld 205, 69120 Heidelberg
Registration: Please register via this form

ECTS: 0.5

Prerequisites:

Prior knowledge about version control with Git is required. This can e.g. be acquired by attending the SSC’s introductory course “Version Control with Git” and “Intermediate Topics in Version Control with Git”. This course is intended for researchers that develop their own research software. Participants are required to bring their own laptops to work on during the course. Network access (e.g. through Eduroam) is recommended.

Summary:

Applying version control can be a game changer for a collaborative research software project. However, even in projects that already successfully use Git, there is often room for improvement of the employed Git workflows. This workshop explores some advanced topics that increase the participants’ repertoire of Git workflows: Bisection, Worktrees, Submodules, Large File Storage and Pre-commit Hooks. Additionally, we showcase invasive methods of modifying a Git repository via Rebase.

Learning Objectives:

After the course participants will

- Know about advanced Git features like submodules, large file storage
- Be able to bisect regression in a Git repository
- Understand the advantages of worktrees
- Be able to apply pre-commit hooks for their Git repositories
- Have used Rebase to change a repository’s Git history

Computational modeling of the cardiovascular system can help to understand the relevant mechanisms and help to tailor treatments for heart diseases. We introduce a fully coupled PDE system for electrophysiology and cardiac mechanics combined with ODEs of ionic concentrations, the blood pressure in the cardiac chambers and a model for the circulatory system.

The model is realized in the parallel software system M++, and we show that the full model for a heart beat is scaling very well on modern HPC systems.

Compact Courses

Speaker: Prof. Dr. Antonio Capella Kort • National Autonomous University of Mexico (UNAM) • Romberg Visiting Professor
Location: Mathematikon • Seminar Room 11, 5th floor • Im Neuenheimer Feld 205, 69120 Heidelberg
Registration: Please register here

ECTS: 2

This course is part of the HGS MathComp Romberg Visiting Professor Program.

This lecture presents some basic topics on probability, Bayesian statistics theory, analytical results on partial differential equations (PDEs) and inverse problems. The combination of these methods led to general approaches that can be used to derive efficient and robust approximations to solve inverse problems with uncertainty quantification. By the end of this course, students will gain insights into how these methods contribute to providing more accurate and reliable schemes to solve inverse problems with uncertainty quantification.

In the practice sessions, we present specific inverse problems, allowing the students to actively engage with the material and develop practical solutions through coding exercises.

Syllabus:

- Introduction: mathematical models and inverse problems.
- Basic topics in probability theory and functional analysis.
- Inverse problems, Bayesian inference and uncertainty quantification.
- Existence and consistency (stability) of posterior distributions.
- Exploring the posterior and sampling methods.
- Stability estimates for linear PDEs and physically informed models.

- Day 1: 2 x 90 minutes sessions
- Day 2 to 4: 1 90 minutes session + 1 90 minutes practice session

Target group

This workshop is designed for doctoral candidates with previous presentation experience.

Objectives

"Wow, that presenter is so good in front of an audience. If only that were easier for me!" Being a good speaker is often just a question of developing a set of skills and techniques. The use of voice and body language, an effective presentation structure and the dynamic use of language require awareness and practice. The workshop helps to identify and explore these requirements, from self-reflection to self-assurance and long-term excellence.

Description

This seminar provides participants the opportunity to improve their conference presentation skills. Constructive feedback from the trainer and group members give the speaker a healthy amount of input while practicing new ideas and techniques to enhance the quality of their speech and overall impact of the talk.

Participants will be required to prepare a 3 to 5 minute overview of their work; the use of slides is optional. This will provide a basis for applying the practical aims of the workshop.

Throughout the two-day workshop, participants will be guided through interactive exercises to improve non-verbal communication, improve the ability to listen and react generously, and to integrate focusing techniques, which empower the speaker. Attention will also be given to structural and language aspects to improve clarity and flow of the talk.

Explaining the simplicity of the cosmos

Colloquium

Speaker: Prof. Neil Turok • Higgs Chair of Theoretical Physics, School of Physics and Astronomy, University of Edinburgh (UK)
Location: Lecture Hall Building • Lecture Hall 1, Im Neuenheimer Feld 308, 69120 Heidelberg
Link:

ECTS: 0

Prof. Turok's lecture will take place in connection with the colloquium of the 52nd Heidelberg Graduate Days - Hans Jensen Invited Lecture.

Observations of the cosmos on the largest visible scales have revealed it to be amazingly simple. Likewise, the Large Hadron Collider has found no new particles on the tiniest scales probed. In contrast, the most popular theoretical paradigms including string theory and inflation, have grown increasingly complex and contrived. We have therefore launched a search for more economical and predictive explanations. In the process, we stumbled upon 1) the simplest-yet explanation for the cosmic dark matter, soon to be tested by galaxy surveys, 2) a thermodynamic explanation for the large scale geometry of the cosmos, based on an elegant new calculation of gravitational entropy, 3) an explanation of the big bang singularity as a kind of “mirror” which enforces CPT symmetry (the deepest known symmetry of nature, linking particles to antiparticles), and 4) a new explanation of the primordial density variations which led to the formation of galaxies, explaining them quantitatively in terms of known physics. I’ll outline the new theory’s main challenges and opportunities, ranging from understanding the Higgs boson to consistently coupling the quantum fields of the Standard Model to gravity, as well as future observational tests.

On the internet, video formats have long conquered the world. YouTube has long since overtaken television, especially among the younger generation, and many people move naturally in the world of short videos. In science, however, a large part of the community still shies away from using this medium.

In this workshop we will discuss the basics of (short) video production from the idea to the final upload. More importantly, we will shoot our first videos and gain our own experience with the medium of science video. In particular, we will also address the type of equipment needed and options for each budget.

Topics (selection)

- Equipment for video production
- Basics of video storytelling
- Video production from start to finish
- Best practice in recording
- Introduction to video editing software
- Upload to popular platforms

The possibility to record video formats should be given. A smartphone is sufficient for this purpose. Essential video equipment (light, audio and video hardware) will be provided.

In the academic world, clear, concise, and well-written texts play an important role in convincing journal editors and conference organisers to accept a paper for review and publication, or to invite a researcher to present at a conference. This workshop supports PhD students and novice researchers who need to produce scientific papers in English. Providing participants with strategies to write short texts efficiently and effectively, it also focuses on standards of professional papers aimed at Anglo-Saxon or international research communities. It enables participants to organise ideas and structure texts effectively, to present their own and other researchers‘ findings and opinions appropriately, and to use correct terminology and vocabulary.

During the workshop, participants work with their own texts as well as with examples from their own disciplines that they bring along and consider to be particularly well written. They discuss features of good scientific papers and are equipped to use adequate language in different genres and for different audiences. In addition, they receive peer feedback on their own drafts. All exercises empower them to produce clearer, and more correct, concise, and reader-oriented papers.

The two-day workshop covers the following topics:

- taking inventory: participants‘ strengths and challenges in writing scientific papers in English
- a brief introduction to research and writing processes
- using text analysis to become a better writer
- reporting findings, ideas, and opinions professionally and adequately
- making yourself understood: principles of clear and concise writing
- structuring ideas, organising texts: transitions, connectives, & co.
- working effectively with co-authors and constructive text feedback
- useful online and offline resources

Mathematics is the language of models. Games are models, abstractions to the world we live in. So naturally, playing games can be supported by modeling them with mathematics.

In this short talk on the occasion of the international day of mathematics 2024, we will motivate the link between games and math using several small examples, from abstract strategy games to the latest board games on the market. Follow us and embark on the endeavour to understand tactical and strategic aspects of games using the internationally acknowledged language of models.

Finally, we will present a small riddle based on the game "road to 300". Participants are encouraged to try their hands on this exercise in using your own wits (or perhaps the help of a computer) to win the game - and some prizes.

This event is part of the collaboration between IWR, Heidelberg University and the African Institute of Mathematical Sciences AIMS in Cape Town, SA. The collaboration project heiAIMS is sponsored by the BW Foundation.

- Phase 3: June 24 - 28, 2024
Physical Master Class in Copenhagen (approximately 24 hours of lectures plus 5 hours of exercises).

The course is worth 7.5 ECTS. Registration deadline: March 1, 2024

Please contact Angela Queisser for funding options through 4EU+ and HGS MathComp. For more information and to register, please visit the course page 4EU+: Quantum Information and Quantum Many-Body Theory – University of Copenhagen (ku.dk).

We are currently witnessing the second quantum revolution and with it the advent of quantum technological devices for information processing purposes. Understanding these systems and their capabilities as well as developing robust algorithms for them, requires a fundamental understanding of complex quantum many-body systems as well as ways to characterize their properties efficiently. Within this course, we will help the participants to obtain proficiency in all of these aspects of quantum theory. A tentative list of topics includes:

- Entanglement/Non-Locality
Lecture 1: States, Measurement, Tensor Product, Maximally Entangled State
Lecture 2: Tensor Product (contd.), Density Matrices, Reduced States, Entropy, Entanglement Entropy.
Lecture 3: Bell-inequalities, Bell’s Theorem, Non-local Games/Protocols.

- Quantum Spin-System
Lecture 1: Spin Hamiltonians, Spin-½ Heisenberg Model, SU(2), Ground States, Ground State Energy
Lecture 2: Free Energy, Thermodynamic Limit, Thermal State
Lecture 3: Symmetry Breaking, Mermin-Wagner
Lecture 4: AKLT, Matrix Product States

For each of these topics, we will provide introductory lectures to get students acquainted with the topics before entering into the in-person phase, where experts and practitioners of these fields will give further insight.

Learning Outcome:

The goal is to provide the students with a blended learning approach to the course content on the mathematics of quantum theory with special emphasis on complex quantum many-body systems and quantum information theory. The main intended learning outcomes include an overview of the latest developments in those fields. Furthermore, the course will help the participants to develop competencies to engage in self-organized cross-university and interdisciplinary collaborations via online group work as well as to give and receive peer-feedback on results. Inviting external experts in the field will also give young researchers in the field the opportunity to grow their professional network considerably.

After the talk, we invite everyone to stay for discussions as well as for tea, coffee and cake.

Single-cell RNA-sequencing records the expression values of thousands of genes in individual cells, making the study of cell functionality and development possible at high resolution. To understand the structure of single-cell data on a global level, topological descriptors, such as the presence of loops or voids in the data, are useful. For instance, loops might challenge the assumption of hierarchical cell development or be indicative of missing data in datasets of fully differentiated cells. The established computational tool for detecting the topology of point clouds is persistent homology. However, single-cell data is high-dimensional and notoriously noisy. We show that in high dimensionality traditional persistent homology becomes very sensitive to noise and fails to detect the correct topology. The same holds true for existing refinements of persistent homology. As a remedy, we find that spectral distances, such as diffusion distance and effective resistance, allow persistent homology to detect the correct topology even in the presence of high-dimensional noise. In particular, persistent homology with spectral distances can robustly detect the correct topology of single-cell data.

ECTS: 1 for 5

In this talk, I will venture a glimpse into the future of cutting-edge numerical methods and software for computational fluid dynamics (CFD) for many aerospace applications. While established, off-the-shelf commercial solutions for a broad range of applications exist, the current push towards fundamental changes in the fields of energy generation and transport necessitates computational tools that can keep pace and facilitate discovery through computation.
This talk will give an overview of the ingredients of modern simulation software for CFD, in particular for multi-scale, multi-physics and multi-fidelity problems. Among these are high-order discretization schemes that can adapt locally in space and time to the underlying resolution requirements and thus combine accuracy and robustness. While the potential of leveraging data-driven approaches has become apparent, I advocate for a shift from a purely data-driven to a data-informed approach, which combines both machine learning models (ML) and classical solution schemes consistently. Last but not least, modern discretization methods and ML/CFD hybrid schemes must produce efficient and reliable results. For this, GPU-parallelization and an incorporation of the FAIR principles into the simulation stack must be part of the next generation CFD solvers.

This seminar will help you to make the most effective use of your three years and finish your doctoral thesis on time.
You will also learn and practice the basic concepts of project management – a prerequisite in industries and research institutions.

Working as a PhD student you have the challenging task of developing research findings and write you doctoral thesis within three years. This alone is a demanding job. In addition, it is vital to the scientific process that your findings are presented to the scientific community. For most PhD students this is the first big project in their professional life and it could have a crucial impact on their future professional career. PhD students are highly motivated when they start their PhD studies but may underestimate the need for professional management for this three-year project "doctoral thesis".

This seminar demonstrates how to approach the doctoral thesis in a professional way. Project management tools and techniques are used, tailored to the specific situation of PhD students. You will learn how to set a project vision, define clear objectives, gain buy-in from your supervisor and other colleagues in your group, and how to develop a project plan, which is structured and at the same time flexible enough to easily adjust to unexpected findings. You will establish a "controlling cycle" which helps you to recognize risks and problems as early as possible, and you will learn how to manage critical situations and deal with ups and downs. Furthermore, networking with colleagues, supervisors and other people are important topics of this seminar.

Throughout the seminar, you will work on your own doctoral thesis and share your experience with others. This seminar is most beneficial for PhD students who are in the early phases of their doctoral thesis. At the end of the seminar you will have established a strategy on how to approach your own doctoral thesis. During the follow-up REVIEW we will share experience and best practices and deal with open questions from the first module.

Navigating the challenges of the global COVID-19 pandemic required strategic decisions tailored to each country's unique circumstances. In less developed nations, the threat of overwhelming hospital capacity was especially severe. Rather than building scenarios based on mathematical models, our team used a dynamic forecasting approach. We developed a series of models that provided 4-week probabilistic forecasts, complete with uncertainty quantification. These forecasts, crucially informed by real-time data, predicted the demand for hospital beds and ventilators, which served as the backbone for decisions and public policies adopted by federal health authorities in Mexico from April 2020 to January 2022. The journey was a challenging one. An incompletely characterized virus and the unpredictable dynamics of societal behavior made crafting a useful model difficult.

In this talk, I will present a retrospective of these models and critically review their objectives, successes, and limitations. Our methodology and modeling decisions will be presented, from the intricacies of data used for model fitting to the balance between model complexity and parameter identifiability. The predictive power and performance of our models will also be reviewed. Beyond the algorithms and forecasts, I'll share our experiences collaborating with health authorities and communicating with the general public. Discover the highs and lows, the challenges faced, and the insights we gained.

This event is organized by the Heidelberg Center for Digital Humanities (HCDH) and the Scientific Software Center (SSC).

This presentation consists of two parts and perspectives.

PD Delia Dumitrescu from social/political sciences will speak about communication research using a multi-country, multi-language data set containing COVID-19 social media disinformation posts. Delia will present the initial difficulties related to the dataset and how she approached the Scientific Software Center for support. This support resulted in AMMICO (AI Media and Misinformation Content Analysis Tool): AMMICO is a publicly available software package written in Python 3, whose purpose is the simultaneous evaluation of the text and graphical content of image files. After describing the software features, Delia will provide an assessment of its performance using the social media disinformation posts. This part will conclude by highlighting the tool’s advantages for communication research and by discussing further development ideas.

In the second part of the talk, Dr Inga Ulusoy from the Scientific Software Center (SSC) will speak about the role of the SSC in this project. The initial consultation evolved into a software development project of the SSC. Inga will describe how the project and communication was structured and how the software was designed to fit the needs of the researchers. In the end, Inga will demonstrate how AMMICO can be utilized in further research projects, and conclude by summarizing the ways the SSC can support research projects through research software development and the implementation of software engineering best practices.

Neuroscience-inspired artificial intelligence aims to develop AI systems that learn and act in ways similar to the human brain. This talk will discuss some recent advances in this field, starting with successful examples of neuroscience-inspired machine learning approaches, such as Vector Symbolic Architectures, Hierarchical Temporal Memory, and FlyHash. We also outline recent studies on the similarity of processing in transformers, the deep learning models at the core of Large Language Models, and the structure of brain activities recorded with fMRI during listening tasks. Finally, we discuss the fundamental differences between backpropagation and likely biological learning mechanisms, and explore alternative learning algorithms such as Geoffrey Hinton's forward-forward algorithm. We conclude by examining the implications of these findings for open problems in AI such as one-shot learning, model robustness, and explainability.

Numerical simulations are widely used as a third pillar besides experimental and theoretical investigations in many sciences such as physics and chemistry as well as engineering science. It requires the development of robust and efficient numerical methods for the resolution of the underlying physical laws that arise often in form of partial differential equations (PDEs). In this talk, I will describe two interdisciplinary stories. While illustrating the key-ideas of the theory and methods, I will also highlight the occasions where not only the mathematical tools have been successfully developed and transferred to the application but also where the interdisciplinary interactions raised new mathematical questions and triggered new answers and theories in mathematics. From the application viewpoint, this talk will touch upon implicit solvation models and Born-Oppenheimer molecular dynamics but the methods rely on various and divers mathematical concepts from Grassmann manifolds to descriptors from machine learning and perturbation theory.

Location: Mathematikon • Im Neuenheimer Feld 205, 69120 Heidelberg (Exact room will be announced on the SSC website two weeks prior to the course)
Registration: Please register via this form

ECTS: 1

Prerequisites:

No prior knowledge by the participants is necessary to participate in this course and it is intended for all scientific audiences. Participants are required to bring their own laptops to work on during the course. Network access (e.g. through Eduroam) is recommended.

Summary:

The Unix shell is a powerful tool that allows people to do complex things with just a few keystrokes. More importantly, it helps them combine existing programs in new ways and automate repetitive tasks so they aren’t typing the same things over and over again. Use of the shell is fundamental to using a wide range of other powerful tools and computing resources. The course will include hands-on live coding sessions where participants exercise the learned commands on their own computers.

Version control is the lab notebook of the digital world: it is used to keep track of what was done and to collaborate with other people. Its use is the state of the art in software development projects of all scales. However, it is not limited to software: books, papers, small data sets, and anything that changes over time or needs to be shared can and should be stored in a version control system. The course will include hands-on live coding sessions where participants exercise the learned commands on their own computers.
Learning Objectives

After the course participants will:

- Have a fundamental understanding of how and why to use the Unix Shell
- Be comfortable with handling files and directories using the command line
- Have experience with advanced usage of the shell e.g. loops, pipes, redirects etc.
- Know how to write their workflows as reusable shell scripts
- Understand the benefits of using version control
- Understand basic git terminology
- Have a good working knowledge of common tasks in Git
- See how Git repositories can help them to move towards practicing Open Science

Mutual predictability is the key to interaction. Or in simpler terms: "experience makes teamwork". Of course, prediction isn't all that simple. We'll look at "generative AI", but without the hype, and see how we use that to learn the dynamics of complex stochastic systems, use that to predict -- and control. And give some examples, in robotics and beyond, of where this can be used.

4EU+ Summer School: Modeling and Statistical Analysis of Extremes in Time Series (Copenhagen)
[ more ...]

School

Location: Copenhagen, Denmark
Registration: Please register on the event website

ECTS: 2

The course aims at PhD and advanced Master's students in statistics, probability theory, and econometrics, or with a background in the aforementioned areas such as physics, and geosciences.

This summer school is part of Flagship 3 of the 4EU+ European University Alliance, a close partner of HGS MathComp. Please contact us for funding options through 4EU+ and HGS MathComp.

The understanding of the appearance of extremes in real-life time series (such as weather and climate observations, returns of stock prices, exchange rates, and stock indices, insurance claim data, failures in energy and social networks) requires suitable probabilistic models and their statistical analyses. Over the last 15-20 years such models and statistical tools have been developed under the assumption of serial dependence. They supplement classical extreme value analysis which deals with independent data.

The goals of the course are

- to introduce and discuss the recent developments of extreme value theory in the time series context. The main focus will be on heavy-tail phenomena, where extremes are particularly severe, and clustering effects when extremes appear in clumps,

- to provide suitable statistical tools for analyzing the aforementioned phenomena,

- to provide relevant knowledge to graduate students about extreme behavior of random systems in contrast to their average behavior,

- to learn about applications of extreme value theory from top experts in the field.

Nature-based Solutions for Tackling Global Health Challenges
[ more ...]

School

Location: Heidelberg University
Registration: Please register via this form
Link:

ECTS: 0

An interdisciplinary summer school to equip early-career scientists and practitioners with the main concepts and methods of researching and implementing Nature-based Solutions (NbS), including: theory, study design, data and modelling, financing, determining value and implementation as well as their application to the converging global challenges: climate change and pandemics.

Target Audience:
MSc. and PhD candidates as well as postdoctoral scientists and young researchers from a broad range of disciplines who have a strong motivation to apply NbS in their field of research or work.

Registration Deadline:
before July 26, 2023

In the 21st century, society faces multiple and highly interwoven global health challenges, linked to accelerating climate change, antimicrobial resistance, food and water insecurity, and an increasing number of infectious diseases. Threatening convergence, these health issues call for more effective and sustainable solutions to ensure that the global population continues to thrive. Scientists and researchers can massively contribute to discovering, co-designing, and evaluating these solutions.

In this context, Nature-based Solutions (NbS), while not yet commonplace, are increasingly gaining recognition alongside more conventional engineering solutions and healthcare interventions. The concept of NbS describes the innovative use of existing knowledge about natural systems to assist society in effectively addressing contemporary environmental, social and economic challenges while simultaneously providing ecological and health benefits. These win-win NbS include the management, restoration and protection of ecosystems, strategies for climate adaptation and mitigation and the greening of infrastructure.

The Summer School will explore the innovative potential of NbS to tackle two pressing global health challenges – climate change and pandemic prevention, which are highly interconnected and provide opportunities to design, apply and evaluate a range of win-win NbS to inform future policies based on scientific evidence.

The guest speakers will share their expertise and experience with the participants and will collaboratively work together on a capstone project, relevant to the development and presentation of a research project on NbS to tackle climate change and pandemics.The Summer School will promote interdisciplinary thinking and will encourage participants to bring examples of NbS beyond these two challenges for discussion to consider how to develop NbS that address concrete challenges and implement solutions in very diverse settings. As a result, the Summer School will allow participants to further connect, interact, and build a worthwhile network of expertise on NbS.

Advanced statistical methods are rapidly impregnating many scientific fields, offering new perspectives on long-standing problems. In materials science, data-driven methods are already bearing fruit in various disciplines, such as hard condensed matter or inorganic chemistry, while comparatively little has happened in soft matter. I will describe how we use multiscale simulations to leverage data-driven methods in soft matter. We aim at establishing structure-property relationships for complex thermodynamic processes across the chemical space of small molecules. Akin to screening experiments, we devise a high-throughput coarse-grained simulation framework. Coarse-graining is an appealing screening strategy for two main reasons: it significantly reduces the size of chemical space and it can suggest a low-dimensional representation of the structure-property relationship. I will briefly mention a biological application of our methodology that led to the discovery of in vivo active compounds. Finally, I will mention a number of ways machine learning can help fulfill the promise of connecting models at different scales.

Convolutional Neural Networks (CNN) are the current backbone of deep learning architectures in a wide range of applications which process array data, like 2D/3D images. Despite this overwhelming success of the application of CNNs in terms of qualitative (visual) results and classification test set accuracies, this talk will point out some servere inherent problems of CNNs regarding their insufficient signal processing capabilities.
While these “signal processing flaws” have been largely ignored as test accuracies on many problems have been increasing over many years, recent research showed that current models are highly vulnerable to even the slightest changes in input distributions. In our latest works [1-5], we showed that the missing “robustness” of CNNs is not only due to insufficient training data, but to a large extend is also caused by faulty operators and architectures which are failing to adhere to basic signal processing demands. The aim of this talk is to give an overview of the dominant problems in the context of image processing and analysis and discuss possible counter measures.

ECTS: 0

Machine-learning, which can learn to predict given labeled data, bares many promises for medical applications. And yet, experience shows that predictors that looked promising most often fail to bring the expected medical benefits. One reason is that they are evaluated detached from actual usage and medical outcomes.
And yet, test runing predictive models on actual medical decisions can be costly and dangerous. How do we bridge the gap? By improving machine-learning model evaluation. First, the metrics used to measure prediction error must capture as well as possible the cost-benefit tradeoffs of the final usage. Second, the evaluation procedure must really put models to the test: on a representative data sample, and accounting for uncertainty in model evaluation.

Lecture

Speaker: Nagaiah Chamakuri • IISER, Thiruvananthapuram, India
Location: Mathematikon • Seminar Room B, Ground Floor • Im Neuenheimer Feld 205 • 69120 Heidelberg

ECTS: 0

Informatics for life represents an interdisciplinary alliance of cardiovascular physician scientist and computer scientists from the University of Heidelberg, University Hospital Heidelberg and the Heidelberg Institute for Theoretical Studies.

This talk presents a feasible study of optimal control techniques for cardiac defibrillation based on the bidomain-bath equations posed on a rabbit ventricle geometry. The bidomain model consists of a system of elliptic partial differential equations coupled with a non-linear parabolic equation of reaction-diffusion type, where a set of ordinary differential equations describes the reaction term, modeling ionic transport. Since ODEs describe the ionic currents in the tissue, the PDE part dominates the solving effort. Thus, it is unclear if commonly used splitting methods can outperform a coupled approach by maintaining good accuracy. The results will be presented in the first part based on comparing the coupled solver approach with commonly used splitting schemes to solve more sophisticated physiological models. Consequently, the novel memory-efficient computational technique will be demonstrated to solve the coupled systems of equations. In the second part, the optimal control approach for successful cardiac defibrillation will be shown based on minimizing a properly chosen cost functional depending on the extracellular current as input at the boundary of the bidomain-bath domain.

Second HBPMolSim Training Workshop on Tools for Molecular Simulation of Neuronal Signaling Cascades. This workshop is part of the EBRAINS RI trainings.

Registration deadline: 09.06.2023. This will be a hybrid event.

The human brain is one of the most complex and fascinating structures. It is still far from understood and therefore considered one the last biological frontiers. Its function is the result of intricate signal transmission networks and reactions occurring within and between neurons. To model and simulate such complexity, multiscale models are required that are aimed at reproducing brain function through a bottom-up approach, from the molecular to the whole brain level. This workshop will provide training in some of the computational tools developed in the Human Brain Project that enable brain simulation and modelling at the molecular and subcellular levels. This workshop is intended to offer an overview of these tools and their application and provide students and young researchers with the necessary theoretical background and practical experience to enable them to apply them in their own research. There will be a mix of lectures and practical session as well as discussions of case studies and the participants' own research problems.

About the speaker:

Anil Ananthaswamy is an award-winning science journalist and former staff writer and deputy news editor at New Scientist magazine. Currently, as a freelance journalist, he writes for Quanta, Scientific American, New Scientist and Nature, among others. His most recent book, Through Two Doors at Once was named one of Smithsonian's Favorite Books of 2018 and one of Forbes's 2018 Best Books About Astronomy, Physics and Mathematics. In 2023 Anil Ananthaswamy was selected as “Journalist in Residence" at at the Heidelberg Institute for Theoretical Studies (HITS).

In the early 1800s, Thomas Young performed a homespun experiment with a sunbeam split into two, and challenged our understanding of the nature of light. With the birth of quantum mechanics, starting in the early 1900s, this "double-slit" experiment—now done with individual particles—started challenging our ideas about the nature of reality. How can a single particle behave both like a particle and a wave? Does a particle, or indeed reality, exist before we look at it, or does looking create reality? Is there a place where the quantum world ends and the familiar classical world of our daily lives begins, and if so, can we find it? In the 1960s, Richard Feynman said that the deceptively simple double-slit experiment contains the "central mystery" of the quantum world. Even he would have been amazed at just how far physicists have pushed this experiment, and how it still continues to confound and challenge our intuitions about the nature of reality.

Abstract:

I will discuss our efforts to use machine learning (ML) to accelerate the computational tailoring and design of transition metal complexes for catalysis and metal-organic framework (MOF) materials in spaces of millions to tens of millions of materials. Traditionally, computational modeling with high-throughput screening based on density functional theory (DFT) has been employed for data generation either for direct discovery or when paired with regression ML models. I will describe how we have addressed some of the challenges of applying these workflows in regimes of scarce data. I will describe how we have achieved 1000-fold accelerated discovery of light-harvesting complexes, single-site catalysts, and energy storage materials. To accomplish this, we have quantified uncertainty using measures of the latent space to improve model confidence as well as to drive efficient global optimization workflows with multitask neural networks. I will also describe how we have leveraged natural language processing to extract, learn, and directly predict experimental measures of stability on heterogeneous MOF materials. I will also touch upon how we are beginning to overcome one chief limitation of accelerated catalyst discovery by using diffusion models to predict transition state structrues, the rate limiting step in conventional computational modeling of catalysts.

The lecture will be held in German and English.

The emergence and transmission of pathogens that cause infectious diseases is an increasing threat in Europe, fueled by climate change, globalization, increasing international mobility, amongst many other broad societal and environmental transformations. Since the 2000s, The Upper Rhine Valley in Southwestern Germany has emerged as a hotspot for invasive Asian tiger mosquitoes with their populations persisting despite control and eradication efforts by local and regional administrations.

To address the growing public health risk endemic Asian tiger mosquitoes populations pose in relation to the spread of infectious diseases, it is critical that efforts are undertaken to evaluate the conditions contributing to the establishment of Asian tiger mosquitoes populations as well as how efforts to mitigate and respond to climate change may actually make local environments more suitable to these disease vectors amongst others.

Join professors from Universität Heidelberg to learn about these threats and the impacts of climate change and mobility on disease vectors such as mosquitoes. Speakers will address current research at Universität Heidelberg and its partner institutions as well as the citizen science initiative Mosquito Alert which is working to tackle invasive mosquito populations across the globe.

Abstract:
The world is changing rapidly, accelerating our need to understand how factors like climate, land use, and social structure affect the ecology of disease on a global stage. Interrogating these processes requires applying advanced analyses across broad datasets to ensure that results are generalisable and complexities are well-understood. However, often, disease ecology analyses take relatively coarse species-level approaches that are fraught with sampling biases and are restricted in their ability to inform finer-scale processes. Further, when these models are used to predict the disease consequences of global change they can be difficult to validate, reducing our confidence in their predictions.

In this talk, I present a series of analyses that we have used to identify macroecological trends of host-pathogen ecology and the changing structure of the global host-virus network, and our efforts to use them to predict elements of global change. I compare and contrast them with other finer-scale studies of disease dynamics that comprise most of the field of disease ecology, and I outline the ways we are attempting to move between these scales of investigation. Ultimately, I discuss the need for “bottom-up” mechanistic prediction of disease dynamics in novel systems, using fine-scale analyses to inform the most important global-scale problems.

This 4-day course offers a compact introduction to mathematical optimization. We invite researchers in non-mathematical fields as well as in mathematics to attend the classes.
The goal of the course is to enable the participants to recognize the characteristics of a given optimization problem, to understand its difficulties and limitations, and to choose suitable solution methods as well as to develop ideas on how to model problems from their own field as optimization problems.

We will focus on the following four categories of optimization problems:
day 1) unconstrained optimization
day 2) convex optimization
day 3) nonlinear optimization
day 4) infinite-dimensional optimization

For each of these problem classes, we will study meaningful examples, the relevant theory, and prominent solution algorithms. Every day consists of a 90-minute lecture part in the morning and a 90-minute hands-on exercise session in the afternoon.

Abstract:
First of all, we will define, and recall basic the properties of braids groups and connect them naturally with knot theory.

Title: What Exactly is Infinity?
Speaker: Dr. Michael Winckler • HGS MathComp

Abstract:
The concept of infinity is hard to understand for humans. Counting finite sets is a natural concept, but understand what countably infinite sets are and that we can even investigate uncountably infinite sets is difficult to comprehend.

In this lecture we will start by comparing finite sets and establishing a rigorous method to compare sets in their size. Expanding this to infinite sets will help us to move forward and show that different levels of infinity exist. We will conclude the lecture by trying to visualize our results in drawing space-filling curves, thus experiencing that our notion of size does not easily extend to infinity.

In this talk we discuss randomization techniques for solving large scale linear algebra problems. We focus in particular on solving linear systems of equations and eigenvalue problems. We first introduce a randomized Gram-Schmidt process for orthogonalizing a set of vectors and its block version. We discuss its efficiency and its numerical stability while also using mixed precision. Further randomized GMRES and randomized FOM methods are discussed for solving linear systems of equations as well as randomized Rayleigh-Ritz procedure for solving eigenvalue problems.

Having access to a powerful generative model allows for a wide range of downstream applications, such as probabilistic inference, sampling, data completion, density evaluation, outlier detection, etc. Diffusion models (DMs) are an emerging class of deep generative models that have demonstrated remarkable synthesis quality. DMs rely on a diffusion process that gradually perturbs the data towards white noise, while the generative model learns to denoise. A major drawback of DMs, compared to, for example, Generative Adversarial Networks, is that sampling can be relatively slow.

In this seminar, I will give an accessible introduction to DMs and present our work on critically-damped Langevin DMs (CLD) which is based on ideas from statistical mechanics. CLD can be interpreted as running a joint diffusion in an extended space, where the auxiliary variables can be considered "velocities" that are coupled to the data variables as in Hamiltonian dynamics. CLD significantly accelerates sampling compared to the original DM formulation, however, many further improvements can be made by borrowing ideas from the ODE solver literature.

Our brains are comprised of billions of neurons that form a complex network. This network is a result of both evolutionary optimization (fostering a modular arrangement including highly specialized areas) and our own experience (storing memories and skills by adapting connection strengths) and determines how we process sensory input to produce meaningful responses. Since neurons communicate with short electrical pulses only when necessary, they are extremely energy efficient. Given our worldwide increase in computing demand, there is thus a strong incentive to develop low-energy neuromorphic computing paradigms that mimic the working principles of the brain. But what are the relevant working principles of the brain? How does a neural network develop useful dynamics? In this seminar, I will present minimal principles to ensure stable collective neural dynamics from a statistical physics perspective, discuss how these can be used to tune network states to task requirements and show how they can be applied to neuromorphic computing. While I mainly focus on experience-driven self-organization, I will finish with some ideas to include evolutionary-driven architectures in the future.

The large-data limit of the MBO scheme for data clustering

ECTS: not yet determined

The MBO scheme is an efficient algorithm for data clustering, the task of partitioning a given dataset into several meaningful clusters. In this talk, I will present the first rigorous analysis of this scheme in the large-data limit.
The starting point for the first part of the talk is that each iteration of the MBO scheme corresponds to one step of implicit gradient descent for the thresholding energy on the similarity graph of the dataset. It is then natural to think that outcomes of the MBO scheme are (local) minimizers of this energy. We prove that the algorithm is consistent, in the sense that these (local) minimizers converge to (local) minimizers of a suitably weighted optimal partition problem.
To study the dynamics of the scheme, we use the theory of viscosity solutions. The main ingredients are (i) a new abstract convergence result based on quantitative estimates for heat operators and (ii) the derivation of these estimates in the setting of random geometric graphs.
To implement the scheme in practice, two important parameters are the number of eigenvalues for computing the heat operator and the step size of the scheme. Our results give a theoretical justification for the choice of these parameters in relation to sample size and interaction width.
This is joint work with Jona Lelmi (University of Bonn).

Minicourse: Introduction to Mathematics of Deep Learning
Leonid Berlyand • Pennsylvania State Universtiy, USA
October 26-27, 2022 • 14:30 - 16:30

Abstract:
The goal of this minicourse of four lectures is to introduce basic concepts from deep learning in a rigorous mathematical fashion, e.g introduce mathematical definitions of deep neural networks (DNNs), loss functions, the backpropagation algorithm, etc. We attempt to identify for each concept the simplest setting that minimizes technicalities but still contains the key mathematics. This minicourse follows the upcoming book “Mathematics of Deep Learning: an introduction” by L. Berlyand and P.-E. Jabin. Publisher: De Gruyter (to appear).

Lecture 1. History, general perspective and basic notions of deep learning

In this lecture, we briefly discuss the general perspective of machine learning:
what is it and why study it? Next, we introduce the classification problem in a supervised learning context and then introduce the key concept of artificial neural networks (ANNs) as the composition of linear maps and nonlinear activation function followed by other basic definitions describing ANNs.

Lecture 2. DNNs and approximation theory

In this lecture, we discuss the universal approximation theorem describing the wide class of continuous functions which DNNs can be used to approximate. This theorem explains the extensive use of DNNs in classification problems. Next, we introduce the concept of training via the gradient descent algorithm which improves the approximate classifier by iteratively __learning__ from the dataset.

Lecture 3. Backpropagation & CNNs

We begin from introducing the notion of computational complexity. Next, we introduce the backpropagation algorithm which significantly reduces the computational cost of optimizing the loss function. This is done in the simplest one neuron per layer setting, which while not practical allows us to explain the concept without many technicalities. Finally, if time permits, we briefly discuss convolutional neural networks and their properties.

Lecture 4. Implementing DNNs and Training: a brief overview of Pytorch

This lecture will be presented by my co-author P.-E. Jabin (Penn State).

We present here a short and very basic introduction to Pytorch, in the context of classification of images. We assume passing familiarity with coding and with python in particular. Many further tutorials exist online and several can be found at https://pytorch.org/tutorials/

From the vision “Stability, Prosperity and Sustainability,” Thailand has adopted “Thailand 4.0” as a policy vision for economic development which aims at driving the country out of a middle-income towards a high-income economy. Underlying this is no other than an attempt to change from the current economic model towards an “innovation-driven economy”—i.e., transitioning from an industry-driven development to a technology-, creativity-, and innovation-driven development by consolidating as well as integrating various fields of knowledge. This, thus, necessitates deepening mathematical research on optimization and numerical methods as it plays a considerable role in providing solutions for a variety of problems including those in such areas as industry, finance, engineering, economics and agriculture.

Realizing the importance of research on optimization and numerical methods, the Department of Mathematics, Faculty of Science, King Mongkut’s University of Technology Thonburi—in cooperation with the Interdisciplinary Center for Scientific Computing (IWR), Heidelberg University, the Federal Republic of Germany, and along with the nationwide as well as the Southeast Asian regionwide network of universities including Walailak University, Prince of Songkla University (Pattani Campus), Chulalongkorn University, Silpakorn University, Mahidol University, Chiang Mai University, and King Mongkut’s University of Technology North Bangkok—will organize an international “Workshop on Computational Science 2022: Webinar on Optimization and Numerical Methods in Industries.”

This year, the Department will co-host the event with the Department of Mathematics, School of Science, Walailak University, and the Department of Mathematics and Computer Science, Faculty of Science, Chulalongkorn University.

ECTS: 3

Scientific progress in machine learning is driven by empirical studies that evaluate the relative quality of models. The goal of such an evaluation is to compare machine learning methods themselves, not to reproduce single test-set evaluations of particular optimized instances of trained models. The practice of reporting performance scores of single best models is particularly inadequate for deep learning because of a strong dependence of their performance on various sources of randomness. Such an evaluation practice raises methodological questions of whether a model predicts what it purports to predict (validity), whether a models performance is consistent across replications of the training process (reliability), and whether a performance difference between two models is due to chance (significance). The goal of this tutorial is to provide answers to these questions by concrete statistical tests.

The tutorial is hands-on and accompanied by a textbook (Riezler & Hagmann: Validity, Reliability, and Significance: Empirical Methods for NLP and Data Science Synthesis Lectures on Human Language Technologies, Morgan & Claypool Publishers, 2022) and a webpage including R and Python code: https://www.cl.uni-heidelberg.de/statnlpgroup/empirical_methods/

In this talk I will present a geometric multilevel optimization approach choosing as case study a regularised inverse problem. In particular, the approach is motivated by variational models that arise as the discretization of some underlying infinite dimensional problem. Such problems naturally lead to a hierarchy of discretized models. We employ multilevel optimization to take advantage of this hierarchy: while working at the fine level we compute the search direction based on a coarse model. By utilising concepts of information geometry in our formulation, we propose a smoothing operator that only uses first-order information and incorporates constraints smoothly. We show that the proposed algorithm is well suited for ill-posed reconstruction problems and demonstrate its efficiency on several large-scale examples.

In statistics, stochastic processes are the main tool for modelling spatial and temporal data, and the most commonly used type are the Gaussian processes. A popular approach to define Gaussian processes is through linear stochastic differential equations driven by white noise. This methodology is often denoted the SPDE approach. By utilising methods from numerical analysis one has been able solve several of the computational bottlenecks that have hampered the usage of Gaussian processes for real world data sets, in particular for spatial statistics. I will focus on how one can apply the same methodology to create non-Gaussian processes, in space and time. I will also discuss what practical properties these processes have over their Gaussian counterpart. Further, I will present very recent work where we have extended the SPDE approach for Gaussian process, to Euclidean graphs (like street networks). Here the linear differential operators are obtained using Quantum graphs, which opens these methods for a new wide range of applications.

Predicting the emergent properties of a material from a microscopic description is a scientific challenge. Machine learning and reverse-engineering have opened new paradigms in the understanding and design of materials. However, the soft-matter field has lagged far behind in embracing this approach for materials design. The main difficulty stems from the importance of entropy, the ubiquity of multi-scale and many-body interactions, and the prevalence of non-equilibrium and active matter systems. The abundance of exotic soft-matter phases with (partial) orientation and positional order like liquid crystals, quasicrystals, plastic crystals, along with the omnipresent thermal noise, makes the classification of these states of matter using ML tools highly non-trivial. In this talk, I will address questions like: Can we use machine learning to autonomously identify local structures, detect phase transitions, classify phases and find the corresponding order parameters in soft-matter systems, can we identify the kinetic pathways for phase transformations, and can we use machine learning to coarse-grain our models? Finally, I will show how one can use machine learning to reverse-engineer the particle interactions to stabilize nature’s impossible phase of matter, namely quasicrystals?

Deep learning-based approaches have revolutionized virtually all domains of computer vision, including the field of microscopy image analysis. In image reconstruction and classification, in segmentation and artificial labelling, they have pushed both flagship projects and bread-and-butter everyday tasks, allowing image analysis to keep pace with the recent advancements in imaging technology and instrumentation. I will talk about the recent work of my group that has enabled the first segmentation of cells in a whole animal imaged with electron microscopy, our collaboration with microscope developers for trusted reconstruction of light field microscopy and our current efforts to reduce the annotation budget for training of segmentation algorithms. I will also show how we strive to make our methods accessible to biologists without computational expertise through our software ilastik and through the emerging community network collection at the BioImage Model Zoo.

Multiscale Methods
[ more ...]

Seminar

Speaker: Prof. Robert Scheichl & Linus Seelinger • IWR
Location: TBD.
Link:

ECTS: 6

Topic:
Natural or engineered materials often contain two or more key constituents, arranged in a heterogeneous structure varying at different scales. Such materials are desirable because their macroscopic properties can be superior to the properties of the individual constituents. It is even possible to explicitly design them for a particular purpose by changing the composition of the constituents.

An example are carbon fibre composites for lightweight structures and vehicles. The mathematical modelling of such heterogeneous or composite materials typically leads to PDEs with highly oscillating coefficients. Direct numerical solution of such problems with traditional methods, such as finite elements is computationally expensive. Just to compute the correct qualitative behaviour, the mesh resolution would need to be sufficiently high to capture all the fine scale variation.

In this seminar, we will study multiscale numerical methods that address various aspects of this challenge. This includes the generation of low-dimensional yet high-quality approximation spaces, acceleration of fine-scale solutions and efficient uncertainty quantification for multiscale problems.

Each student will present a key publication on multiscale numerical methods with an aim to cover most aspects of the field.

Prerequisites:
Basic knowledge of partial differential equations, Sobolev spaces and Finite Element methods is required. For the uncertainty quantification topics, basics of probability theory are needed.

Have you sat in front of an empty sheet of paper or an empty file before, trying to start a report, a paper or your PhD Thesis, but struggling to make progress? Or have you had to read a research article relevant to your PhD project that was so incomprehensible or dry that you were wishing to be somewhere else for the day to end? Good scientific writing is an absolutely essential part of our work as researchers; only through good communication will we be able to captivate the audience and truly enthuse them for our achievements and results. It is as important as pure academic ability for a successful professional career in academia, but also in industry, but typically we are not trained formally in good writing in a mathematics or science degree. In this crash course I aim to give you some useful pointers on good writing in the mathematical sciences, and through some hands-on exercises we will try to immediately put them in practice.

Working as a PhD student you have the challenging task of developing research findings and write you doctoral thesis within three years. This alone is a demanding job. In addition, it is vital to the scientific process that your findings are presented to the scientific community. For most PhD students this is the first big project in their professional life and it could have a crucial impact on their future professional career. PhD students are highly motivated when they start their PhD studies but may underestimate the need for professional management for this three-year project "doctoral thesis".

This seminar demonstrates how to approach the doctoral thesis in a professional way. Project management tools and techniques are used, tailored to the specific situation of PhD students. You will learn how to set a project vision, define clear objectives, gain buy-in from your supervisor and other colleagues in your group, and how to develop a project plan, which is structured and at the same time flexible enough to easily adjust to unexpected findings. You will establish a "controlling cycle" which helps you to recognise risks and problems as early as possible, and you will learn how to manage critical situations and deal with ups and downs. Furthermore, networking with colleagues, supervisors and other people are important topics of this seminar.

Throughout the seminar, you will work on your own doctoral thesis and share your experience with others. This seminar is most beneficial for PhD students who are in the early phases of their doctoral thesis. At the end of the seminar you will have established a strategy on how to approach your own doctoral thesis. During the follow-up REVIEW we will share experience and best practices and deal with open questions from the first module.

This seminar will help you to make the most effective use of your three years and finish your doctoral thesis on time.
You will also learn and practise the basic concepts of project management – a prerequisite in industries and research institutions.

Uncertainty quantification plays an important role in many engineering applications. In this talk we discuss some recent advancements in the approximation of high-dimensional functions appearing in this context. We provide new results for surrogate modeling and parameter estimation in cases where the uncertainty is described by a Gaussian random field. Additionally we address how the usage of neural networks to learn linear and nonlinear operators may help in solving such tasks, and what possible challenges might lie ahead.

The IWR Colloquium will be held as an in-person event at the Mathematikon. In addition it will be streamed via Zoom.

Workshop

Speaker: Dr. Jan Schmidt
Location: Virtual Workshop

ECTS: 1

We all have different networks - no matter whether we call them "network" or not. These networks provide support, advice and help in different fields. To better use and understand them it is crucial to be aware of the fact that the purpose influences the network itself. If our purpose (or aim or goal) remains unclear efficient networking is impossible. The workshop "Purposeful Networking" provides basic information on networking and gives space to clarify personal aims - to create a link between network and purpose.

---------------------------------------------------------------------------

Spatial and temporal control of molecular phenomena is crucial to develop intelligent materials for applications ranging from sensing over catalysis to photonic computing. In this regard, stimuli-responsive molecules enable to influence structural and dynamic properties at the atomic level in a highly controlled manner by external stimuli such as light.

To transfer external inputs into functionality, a detailed understanding of both, the operation mechanism of the responsive species and their impact on the environment, is needed. In the presentation, I will give an overview of our activities on developing and applying theoretical methods to investigate the dynamics of stimuli-responsive systems at different time and length scales. By establishing an automated and first-principle based parametrization approach for interatomic potentials, investigations of equilibrium and out-of-equilibrium phenomena in responsive and functional materials are performed.

My presentation is divided in three parts, which cover our atomistic investigations on (i) responsive molecular species (e.g. molecular switches/machines), (ii) the dynamic intermolecular interplay during molecular aggregation and atomically precise restructuring and (iii) hierarchal and responsive architectures (e.g. phase change material and functionalized Metal-Organic Frameworks). By directly linking of our multi-scale simulations with experimental techniques, our work contributions to a rational development of responsive and functional materials.

Romberg Inaugural Lecture: Model Order Reduction Methods for Time-Harmonic Wave Problems
[ more ...]

IWR Colloquium

Speaker: Prof. Francesca Bonizzoni, Romberg Visiting Scholar
Location: Virtual Talk
Link:

ECTS: not yet determined

Many engineering applications require the numerical evaluation of time-harmonic wave propagation problems over a range of frequencies. The most used technique to discretize partial differential equations is the finite element method. Due to the oscillations of analytical solutions the finite element discretization often becomes computationally expensive.

Model order reduction methods provide reliable approximations of the solution at low computational cost. In particular, they allow very fast responses both for real-time and multi-query contexts.

This talk deals with novel model order reduction techniques tailored to time-harmonic wave problems relying only on a precomputed set of snapshots, they present great flexibility, since they allow the construction of a surrogate starting from snapshots obtained via black-box solvers (e.g., commercial software).

The method’s efficiency is investigated in several examples, including transmission-reflection and scattering problems. Especially in the context of optimal control problems, where standard numerical techniques are unfeasible, the employment of surrogate models is crucial.

Deep learning is fueling advances and breakthroughs in a dizzying array of data-intensive scientific fields. In this talk, I will highlight recent and ongoing work of our lab that leverages deep learning to push the limits of advanced microscopy.
A long-standing challenge in the life sciences is to visualize biological cells at high resolution and with high throughput. Single molecule localization microscopy (SMLM) is among the most powerful and widely used super-resolution imaging methods, but is typically very slow and low throughput. I will present ANNA-PALM, a computational technique based on deep learning that can reconstruct high resolution views from strongly under-sampled SMLM data and widefield images, enabling considerable speed-ups without any compromise on spatial resolution. I will also highlight Shareloc, an online platform to facilitate the sharing and reanalysis of SMLM data, and Imjoy, a computational platform dedicated to facilitating the uptake of state-of-the art deep learning methods in the biomedical research community.

Die Aufnahme, Speicherung und Weitergabe großer Mengen von Daten ist eine Aufgabe, der sich menschliche Gesellschaften bereits seit Jahrtausenden zu stellen haben. Einen der größten Meilensteine bildet dabei die Erfindung der Schrift, zuerst nachweisbar im Mesopotamien des 4. vorchristlichen Jahrtausends. Zeugnisse dieses Quantensprungs finden sich unter anderem in der Heidelberger Uruk-Warka-Sammlung, die spektakuläre Funde aus dem Sitz des mythischen Königs Gilgamesch bewahrt. Diese Objekte zeugen jedoch nicht nur von den Leistungen antiker Archivare, sie stellen auch eine Herausforderung für ihre modernen Nachfolger dar. Mit welchen Methoden lassen sich archäologische Daten heute sammeln, bewahren und austauschen?

Antworten darauf liefert das Heidelberger "Forensic Computational Geometry Labratory" (FCGL), an dem Methoden zur Digitalisierung archäologischer Artefakte entwickelt werden. Mittels eines Laserscanners werden die Objekte aufgenommen und über das Programm Gigamesh in digitale 3D-Modelle umgesetzt. Unter anderem kommt dieses Verfahren im Projekt "Scanning for Syria" zum Einsatz, in dessen Zentrum die Sicherung von durch den syrischen Bürgerkrieg bedrohten Kulturgütern steht. Das HAIlight im März bietet Ihnen die Gelegenheit, den Forschern am FCGL bei ihrer Arbeit mit Objekten der Uruk-Warka-Sammlung über die Schulter zu schauen.

Das HAIlight findet am Freitag, den 27.03.2020 um 18:00 Uhr statt und dauert ca. eineinhalb bis zwei Stunden. Die Plätze für die Teilnahme sind begrenzt und werden nach Ablauf der Rückmeldefrist verlost. Details zu Treffpunkt und Veranstaltungsort erhalten Sie in der Teilnahmebestätigung.

Für die Platzvergabe schicken Sie uns bitte bis spätestens Montag, 16.03.2020 unter Angabe Ihres Namens eine E-Mail an hailight@alumni.uni-heidelberg.de.

Talk - "Mathematics of Life" Special Interest Group

Climate change, increasing human mobility and trade, pathogen evolution and resistance, urbanization, and ecological range shifts - all these global factors destabilize the current pattern of infectious diseases, notably those transmitted by vectors. There is general agreement that this will lead to the emergence and re-emergence of a wide range of infectious diseases. In Europe, water and vector-borne diseases such as Vibriosis, Dengue, Chikungunya, West Nile Virus, Lyme disease and Tick-borne encephalitis are proliferating and emerging among previously immunologically naive populations. This may result in severe disease outbreaks, morbidity, mortality, long-term disability and increasing burdens of disease. In Low-and-Middle-Income Countries (LMICs), Ebola has not yet been contained, malaria, Dengue and cholera are still associated with massive disease burdens, and arboviruses are likewise on the rise. Globally, resistance to antibiotics and insecticides is a growing concern. New genotypes and new pathogens are threatening to unleash pandemics with potential to have major societal impact, if not effectively monitored and controlled. The recent Corona virus situation is a good example of how sensitive the global population is to local emergence of viruses with epidemic potential. Achieving the sustainable development goals 2030 requires new methods for monitoring, surveillance and analysis, all of which are key for the deployment of more efficient, timely and strategic prevention.

To address these unprecedented global challenges, the public health professions are called on to develop new approaches and innovative techniques and solutions. We are now entering a world, where increasing availability of high quality, high-dimensional data and advanced computation techniques allow for previously unimaginable levels of precision and granularity with respect to monitoring and forecasting of disease outbreaks, their associated burdens and intervention demands. Digitalization, machine learning and artificial intelligence are still in its infancy in terms of public health applications, but hold great promise for revolutionizing public health decision-making, and for sustaining and safeguarding the global population.

This talk provides a few examples on how data from many different disciplines and domains, including climate, human mobility and social media, can be integrated in machine learning, and help timely risk assessment, better forecasts and support the development of more effective prevention strategies. In the talk I will discuss the methods, findings and give examples of tangible decision tools in the making in collaboration with public health policy makers.

ECTS: 2

In times of global pressure on universities the principle of academic freedom is fiercely debated within and outside academia. But surprisingly few academics and even less students have fundamental knowledge what academic freedom is – and what it is not. Debates and actions are often driven by emotions and subjective feelings about a ”proper university“ instead of well founded information.

In this course, participants will

I. discuss the principle of academic freedom – its history, its juridical status and its formal applicability

II. learn to discern academic freedom and other civil liberties (e.g. open speech, freedom of opinion)

III. understand the complexity of taking action in the face of violations to academic freedom

IV. sharpen our awareness for threats to academic freedom in our own societies.

The course material is in English and discussions will be a mixture of English and German (summaries in English will be possible). We expect engagement and interest – no marks will be given!

The course will be held in consecutive blocks. *Friday sessions* are compulsory (course of one hour/1 stündig), Saturday sessions are optional (course of two hours/2-stündig).

IWR Colloquium & HGS MathComp Von Neumann Lecture

A traditional goal of algorithmic optimality, squeezing out flops, has been superseded because of evolution in architecture. Flops no longer serve as a reasonable proxy for all aspects of complexity. Instead, algorithms must now squeeze memory, data transfers, and synchronizations, while extra flops on locally cached data represent only small costs in time and energy. Hierarchically low-rank matrices realize a rarely achieved combination of optimal storage complexity and high-computational intensity in approximating a wide class of formally dense linear operators that arise in applications for which exascale computers are being constructed. They may be regarded as algebraic generalizations of the fast multipole method. Methods based on these hierarchical data structures and their simpler cousins, tile low-rank matrices, are well proportioned for early exascale computer architectures, which are provisioned for high processing power relative to memory capacity and memory bandwidth. Hierarchically low-rank matrices are ushering in a renaissance of computational linear algebra. A challenge is that emerging hardware architecture possesses hierarchies of its own that do not generally align with those of a given algorithm-application pair. We describe modules of a software toolkit, hierarchical computations on manycore architectures (HiCMA), that illustrate these features and are intended as building blocks of applications, such as matrix-free higher-order methods in optimization and large-scale spatial statistics. Some modules of this open-source project have been adopted in the software libraries of major vendors.

Many of the most relevant observables of matter depend explicitly on atomistic and electronic details, rendering a first principles approach to computational materials design mandatory. Alas, even when using high-performance computers, brute force high-throughput screening of material candidates is beyond any capacity for all but the simplest systems and properties due to the combinatorial nature of chemical compound space, i.e. all the compositional, constitutional, and conformational isomers. Consequently, efficient exploration algorithms exploit implicit redundancies and correlations. I will discuss recently developed statistical learning based approaches for interpolating quantum mechanical observables throughout chemical compound space. Numerical results indicate remarkable performance in terms of efficiency, accuracy, scalability and transferability.

Talk

Speaker: John Sanday, OBE, FSA
Location: Mathematikon, Conference Room, Room 5/104, 5th Floor, Im Neuenheimer Feld 205, 69120 Heidelberg

ECTS: not yet determined

The Prelude: Pioneering the Development of Conservation Technology in Cambodia

The Sequel: Pioneering the Use of Digital Technology in Banteay Chhmar with the IWR, Heidelberg University

John Sanday who is a Conservation Architect, has spent the last 45 years working in Asia. For at least 15 of these years he has worked in Cambodia. Arriving for the first time in Siem Reap in 1989, John and his team pioneered one of the first projects in Angkor - the Preah Khan Conservation Training Project which was supported by the World Monuments Fund. John’s early memories were of the Khmer Rouge skirmishes which were still taking place on the outskirts of the historic city of Angkor – it was a memorable start to several decades of work in one of the greatest monumental cities of its time, which was placed on the UNESCO World Heritage List in 1992.

In the first part of his talk, John will describe his early days of setting up the first major conservation-training programme in the 12th Century Buddhist monastic complex of Preah Khan. He will talk about some of the problems they had to face and the techniques developed in Preah Khan and three other sites in Angkor. There will be illustrations showing Angkor as John found it in the 1990’s and it will set the background for him to side track to another major Khmer site in the far North of Cambodia.

John will dedicate the second half of his talk to one of the lesser known but highly significant Khmer sites known as Banteay Chhmar, which is closely linked to Angkor. This 12th Century Buddhist, monastic complex stylistically emulates the temples in Angkor and belongs to the Bayon period. Banteay Chhmar became John´s link with IWR and its team. John and Hans Georg Bock had been fantasizing for many years on trying to link heritage conservation with applied mathematics. Here in Banteay Chhmar, they initiated an extraordinary project and a way of using ‘state of the art’ technology to digitally reconstruct iconic face tower as well as sections of the enclosure wall with its exquisite bas-relief carvings. Precise dimensions of hundreds of stone blocks were recorded digitally to recreate the tower, which had to be dismantled and rebuilt, as well as the fallen stones of the bas relief as the first step to their reconstruction.

Khmer architect Dr. Pheakdey Nguonphan (Royal University of Phnom Penh) and Dr. Anja Schäfer (IWR) developed the digital technology and formed a multi-disciplinary research team including stone masons from Preah Khan. John will describe the system, that was developed to solve “John’s Puzzle” and illustrate how the stones began to recognize their original positions in the structures, without having to move the stones manually.

There will be time for questions and discussion at the end.

Industry’s demand for using big data analysis tools is growing evermore. Public clouds developed in recent years have provided various data analysis tools for analysts, data scientists, researchers, and academics without the burden of permanently allocating and continuously maintaining high performance computing facilities. Google Cloud Platform (GCP) is one of the public cloud providers with a variety of state-of-the-art products addressing wide range of challenges in data engineering and data analytics.
The internet age and growth of social networks was a game changer for human sciences. If previously researchers and analysts had to carefully design data collection processes, now people are sharing their thoughts and concerns on a daily (or hourly) basis. In this workshop we are going to introduce GCP pipelines from streaming Twitter API’s data into a data warehouse. Afterwards, we will perform sentiment analysis and network analysis to find the patterns in user’s behavior. Finally, using visualization tools in python, we will prepare effective communication of the results.

Mathematical modelling of epigenetic regulation and its effects on cell differentiation and reprogramming?
[ more ...]

Talk

Speaker: Prof. Tomás Alarcón
Location: Mathematikon, Im Neuenheimer Feld 205, 69120 Heidelberg

ECTS: not yet determined

The inherent capacity of somatic cells to switch their phenotypic status in response to damage stimuli in vivo might have a pivotal role in ageing and cancer. However, how the entry-exit mechanisms of phenotype reprogramming are established remains poorly understood. In an attempt to elucidate such mechanisms, we herein introduce a stochastic model of combined epigenetic regulation (ER)-gene regulatory network (GRN) to study the plastic phenotypic behaviours driven by ER heterogeneity. To deal with such complex system, we additionally formulate a multiscale asymptotic method for stochastic model reduction, from which we derive an efficient hybrid simulation scheme. Our analysis of the coupled system reveals a regime of tristability in which pluripotent stem-like and differentiated steady-states coexist with a third indecisive state, with ER driving transitions between these states. Crucially, ER heterogeneity of differentiation genes is for the most part responsible for conferring abnormal robustness to pluripotent stem-like states. We formulate epigenetic heterogeneity-based strategies capable of unlocking and facilitating the transit from differentiation-refractory (stem-like) to differentiation-primed epistates. The application of the hybrid numerical method validates the likelihood of such switching involving solely kinetic changes in epigenetic factors. Our results suggest that epigenetic heterogeneity regulates the mechanisms and kinetics of phenotypic robustness of cell fate reprogramming. The occurrence of tunable switches capable of modifying the nature of cell fate reprogramming might pave the way for new therapeutic strategies to regulate reparative reprogramming in ageing and cancer

ECTS: 1

Scrum is an agile framework within which people can address complex adaptive problems, while productively and creatively delivering products. Kanban uses a visual system for managing work as it moves through a process, allowing team members to see the state of every piece of work at any time.

Both of them are agile approaches to project management. Agile project management is one answer to the growing speed in which projects need to be delivered and the realization that many projects are not delivered as originally planned. This is especially true for projects with volatile or unclear requirements at project start.

Concepts like continuous improvement, fast feedback cycles, limiting work in progress and transparency can bring value to teams as well as to individuals.

During this workshop you will learn:

- What is Agile? Get an overview of agile principles, values, techniques and methods
- How to use Kanban for your personal use? Boost your productivity and get things done!
- How can Kanban be introduced to a team? Streamline work between team members and create transparency on status
- How can Scrum be adapted in an academic environment? Use a process framework to improve collaboration and knowledge-sharing between lab members and cut down your fixed meeting times

Program:

9:00-12:00

- Agile introduction - origins, mindset & term definition
- Introduction to Scrum Framework
- Introduction to Kanban
- Applying theory into practice (Part 1)
- Personal Kanban - how to gain focus and transparency in your daily work

In the year 2000, the Clay Mathematics Institute selected seven of the most important open problems in modern mathematics and offered a prize of $1 million for a solution to any of them. Nineteen years on, only one millennium prize problem has been solved. In this talk, Prof. David Silvester will discuss the Navier-Stokes existence and smoothness problem, one of the six remaining unsolved problems.

The Navier-Stokes equations are central to fluid dynamics and its applications to engineering and physics, describing viscous turbulent flow, e.g. of air around an aeroplane wing, weather patterns and blood flow through arteries. Despite the wide-ranging applicability of the Navier-Stokes equations, it is still not known whether they always admit smooth solutions, which contain no unphysical "blow-ups", or singularities.

AnyDSL: A Partial Evaluation Framework for Programming High-Performance Libraries
[ more ...]

Talk

Speaker: Sebastian Hack
Location: Seminar Room A, Mathematikon

ECTS: 0

riting performance-critical software productively is still a
challenging task because performance usually conflicts genericity.
Genericity makes programmers productive as it allows them to separate
their software into components that can be exchanged and reused
independently from each other. To achieve performance however, it is
mandatory to instantiate the code with algorithmic variants and
parameters that stem from the application domain, and tailor the code
towards the target architecture. This requires pervasive changes to
the code that destroy genericity.

In this talk, I advocate programming high-performance code using
partial evaluation and present AnyDSL, a clean-slate programming
system with a simple, annotation-based, online partial evaluator. I
will show that AnyDSL can be used to productively implement
high-performance codes from various different domains in a generic way
map them to different target architectures (CPUs with SIMD units,
GPUs). Thereby, the code generated using AnyDSL achieves a performance
that is in the range of multi man-year, industry-grade,
manually-optimized expert codes and highy-optimized code generated
from domains specific languages.

ECTS: not yet determined

Optimal sequential Bayesian inference, or filtering, for the state of a dynamical system requires solving a partial differential equation. For low-dimensional, smooth systems the finite-volume method is an effective solver that gives estimates that converge to the optimal continuous-time values. We develop this finite-volume filter, and give numerical examples that show that the filter we develop is able to handle multi-modal filtering distributions. For higher-dimensional systems the curse or dimensionality may be overcome by representing density functions by an interpolated tensor train decomposition. We give examples of filtering for continuous-time and discrete-time systems.

ECTS: 2

Computational modeling has become more and more important in the life sciences. One important class of models are compartment models and ordinary differential equations are widely used to describe the time evolution of the model components in a deterministic way. This compact course will introduce stochastic compartmental modeling. The objectives of the course are to learn a) methods that allow to simulate stochastic models and b) which effects so called intrinsic stochasticity can have on systems dynamics. These effects will make it evident that specific calibration techniques are needed in order to be able to cope with stochastic effects and exploit their information. The course will c) give a flavor of how calibration can be performed. Time will also be devoted to let the participants learn d) when stochastic modeling is necessary and beneficial.
This course will consist of lectures as well as practical exercises. Therefore, participants are encouraged to bring laptops (please contact me in case laptop sharing is desired). There is no prior software or programming experience necessary.

ECTS: not yet determined

Scientific computing concerns the development of mathematical models and high-performance software able to describe, simulate and learn the behaviour of complex phenomena. Applications can arise from any area of applied sciences (e.g. engineering, physics, biology, chemistry) and typically retain the challenging task of quantifying high-dimensional uncertainty due to known unknowns and unknown unknowns present in the natural system. When this is added to the computational burden of approximating and solving complex mathematical models, the application of standard inference algorithms, e.g. for parameter estimation, prediction or optimization, becomes quickly unfeasible within a reasonable computational budget.

The aim of the workshop is to bring together researchers working in Uncertainty Quantification, Machine Learning and Bayesian Statistics with a particular focus on high- and infinite-dimensional problems from scientific computing, where the sparsity or uncertainty of data requires an integration of inference and learning algorithms with established physical models, such as partial differential equations. Advances in this complex field of research require a concerted effort from many disciplines, which we hope to foster at the workshop.

This workshop is part of the Thematic Semester Uncertainty Quantification, Machine Learning & Bayesian Statistics in Scientific Computing at MAThematics Center Heidelberg (MATCH) in conjunction with the Excellence Cluster STRUCTURES. The financial support from MATCH and from the Heidelberg Graduate School of Mathematical and Computational Methods for the Sciences (HGS MathComp) is gratefully acknowledged.

"Guided Parameter Exploration in Interactive Visualization"
Prof. Stefan Bruckner, University of Bergen, Norway

Over the past decades the field of visualization has firmly established itself as an important and constantly expanding discipline within computer science. Computer-based visualization seeks to provide interactive graphical data representations, taking advantage of the extraordinary capability of the human brain to process visual information. Advanced visualization methods now play an important role in the exploration, analysis, and presentation of data in many fields such as medicine, biology, geology, or engineering. This development, however, has also lead to the fact that there is now a vast number of often very specialized techniques to visualize different types of data tailored towards specific tasks. Hence, particularly for non-experts, it becomes increasingly difficult to choose appropriate methods that will provide the optimal answers to their questions.

In this talk, I will discuss previous and ongoing research on how we can explore and navigate the space of visualizations itself. By consider the interplay between data, visualization algorithms, their parameters, perception, and cognition as a complex phenomenon that deserves study in its own right, we are making progress in providing goal-oriented interfaces for visual analysis. For instance, we can make the modification of input parameters of visualization algorithms more intuitive by normalizing their perceived effects over the entire value range, and provide visual guidance about their influence. Furthermore, by incorporating additional knowledge into the visualization process, we can infer information about the goals of a user, and develop smarter systems that automatically suggest appropriate visualization techniques. This line of investigation leads us along the path towards a new type of visual data science, where automated data analysis approaches such as deep learning are tightly coupled with interactive visualization techniques to exploit their complementary advantages for knowledge discovery in data-driven science.

This talk focuses on four active branches in scientific visualization research: topological analysis, feature extraction, volume rendering, and solver visualization. We examine various roles of topological analysis in flow fields and beyond, we investigate feature extraction in higher dimensions and higher order, we extend volume rendering beyond direct geometrical optics, and we extend scientific visualization from the traditional analysis of simulated data to analysis of the numerical solvers that produce the data. On the application side, we discuss the utility of the investigated visualization techniques in the natural and life sciences, and indicate possible directions of future research.

"Insights from the Pixel Dump: Scientific Image Visualization"
Prof. Thomas Schulz, Universität Bonn

Big, complex, and dynamic image data play an increasing role in science and medicine. This poses important and interesting challenges to scientific visualization, since the traditional visual inspection of raw images is no longer a suitable strategy for their effective and efficient interpretation. Instead, mathematical modeling, feature extraction, and machine learning are required to pre-process the data, and to allow the human user to reason about it at a higher level of abstraction. This talk will illustrate these points with several specific examples from diffusion Magnetic Resonance Imaging, as well as image data from ophthalmic epidemiology.

PIMS-Germany Workshop on Discretization of Variational Eigenvalue Problems
[ more ...]

Workshop

Speaker: Various Speakers
Location: Mathematikon, Im Neuenheimer Feld 205, 69120 Heidelberg
Link:

ECTS: not yet determined

Recent years have seen intense development of discretization schemes for incompressible flow problems in two directions. On the one hand, pairs of discrete spaces with a commuting diagram property for the divergence operator have been developed, with the result that it is now possible to compute actually divergence free solutions with reasonable effort. In particular for high Reynolds number flow, this property is important, since the control of the divergence by the gradient is too weak. Alternatively, penalization of the divergence has been investigated thoroughly with the same goal of achieving better solutions for high Reynolds numbers. On the other hand, replacements for the pressure Poisson problem have been developed, allowing for much faster projection of approximate solutions into the divergence free subspace, in particular with high performance computing in mind. The study of stability of such flows and of critical modes requires the solution of nonsymmetric variational eigenvalue problems. Critical modes are characterized by eigenvalues with small real part, which again may suffer from spurious divergence. In order to approximate such eigenvalues, many flow problems must be solved iteratively, which brings fast solvers back into the game.

The goal of this workshop is convening top researchers in the fields of flow and eigenvalue problems in order to understand the interplay of the interacting components better and to profit from recent research of groups with different focus. Furthermore, its aim is intensifying cooperation between the members of PIMS and universities in Germany with a clear focus on common interest.

PIMS - Germany Workshop on Modeling and Analysis of PDEs for Biological Applications

Workshop

Speaker: Various Speakers
Location: Mathematikon, Im Neuenheimer Feld 205, 69120 Heidelberg
Link:

ECTS: not yet determined

This mini-workshop will bring together experts in modeling and analysis of organizing principles of multiscale biological systems such as cell assemblies, tissues and populations, and collective dynamics of cells. We will focus on questions arising in systems biology and medicine which are related to emergence, function and control of spatial structures, cell-cell interactions, and inter-individual heterogeneity in biological dynamics. Mechanisms of symmetry breaking and establishment of spatial patterns in gene expression leading to different differentiation programmes are central issues of developmental biology, while the understanding of their perturbation and deregulation leading to abnormal development is important in cancer research. Evolution of large scale spatial patches such as, for example, systems of vegetation patterns observed in drylands, is essential for ecosystems. Dynamics of appearance and disappearance of such patterns have a direct economic impact. Spatio-temporal dynamics arising through a diffusion field is also a central theme in characterizing the collective response of microbial particles.

Pattern formation is also an important topic in materials science. For example, the nature of formation and evolution of nano-scale structures in energy conversion devices such as fuel cells and solar cells is decisive for the quality of the performance of these devices. Though some of these patterns are well characterized, there are other that we are only beginning to understand. Mathematical modeling is a powerful technique to address key questions and paradigms in diverse model systems and to provide quantitative insights into the role of the nonlinear and nonlocal interactions within the systems and with the external fields as well as of the growth and transport processes and their impact on the observed patterns.
Although applied to specific biological, ecological, chemical, medical or physical systems, mathematical models allow for a comparative analysis of design principles in diverse systems. The focus of this proposed conference is to present and analyze models of partial and integro-differential equations applied to problems of spatio-temporal patterning. The goal of the meeting is to bring together specialists in Germany and from PIMS universities working on different aspects of the field, including mathematical modeling and applications, analysis of the underlying equations as well as numerical simulation, in order to exchange ideas, present new techniques, and identify challenging new research directions of common interest. The focus will be in identifying and understanding of mechanisms of pattern formation including formation of travelling waves, stationary and dynamical patterns, the effect of mechanical-chemical forces on patterns, stability and bifurcation theory, mechanisms underlying collective dynamics in cell signalling, and the emergence of singularities. Applications to developmental biology, ecology, cell-signalling, and materials science will be presented and discussed.

The outcome of the workshop will be two-fold. Firstly, various mathematical methods and techniques presented for diverse types of model PDE sytems in biology, will lead to cross-fertilization and will help solving in tackling problems related to different applications. Secondly, this workshop will identify common research interests and establish new research collaborations on specific projects among researchers at PIMS and at Universities in Heidelberg, Munster and Berlin.

ECTS: not yet determined

Learning time-series models is useful for many applications, such as simulation and forecasting. In this study, we consider the problem of actively learning time-series models while taking given safety constraints into account. For time-series modeling we employ a Gaussian process with a nonlinear exogenous input structure. The proposed approach generates data appropriate for time series model learning, i.e. input and output trajectories, by dynamically exploring the input space. The approach parameterizes the input trajectory as consecutive trajectory sections, which are determined stepwise given safety requirements and past observations. We analyze the proposed algorithm and evaluate it empirically on a technical application. The results show the effectiveness of our approach in a realistic technical use case.

Afterwards there will be a Meet & Greet with Pizza and Beer (and non-alcoholic beverages)!

A Sequential Homotopy Method for Mathematical Programming Problems

Link:

ECTS: 0

We consider nonconvex and highly nonlinear mathematical programming problems including finite dimensional nonlinear programming problems as well as optimization problems with partial differential equations and control constraints. We present a novel numerical solution method, which is based on a projected gradient/anti-gradient flow for an augmented Lagrangian on the primal/dual variables. We show that under reasonable assumptions, the nonsmooth flow equations possess uniquely determined global solutions, whose limit points (provided that they exist) are critical, i.e., they satisfy a first-order necessary optimality condition. Under additional mild conditions, a critical point cannot be asymptotically stable if it has an emanating feasible curve along which the objective function decreases. This implies that small perturbations will make the flow escape critical points that are maxima or saddle points. If we apply a projected backward Euler method to the flow, we obtain a semismooth algebraic equation, whose solution can be traced for growing step sizes, e.g., by a continuation method with a local (inexact) semismooth Newton method as a corrector, until a singularity is encountered and the homotopy cannot be extended further. Moreover, the projected backward Euler equations admit an interpretation as necessary optimality conditions of a proximal-type regularization of the original problem. The prox-problems have favorable properties, which guarantee that the prox-problems have uniquely determined primal/dual solutions if the Euler step size is sufficiently small and the augmented Lagrangian parameter is sufficiently large. The prox-problems morph into the original problem when taking the step size to infinity, which allows the following active-set-type sequential homotopy method: From the current iterate, compute a projected backward Euler step by applying either local (inexact) semismooth Newton iterations on the step equations or local (inexact) SQP-type (sequential quadratic programming) methods on the prox-problems. If the homotopy cannot be continued much further, take the current result as a starting point for the next projected backward Euler step. If we can drive the step size all the way to infinity, we can transition to fast local convergence. We can interpret this sequential homotopy method as extensions to several well-known but seemingly unrelated optimization methods: A general globalization method for local inexact semismooth Newton methods and local inexact SQP-type methods, a proximal point algorithm for problems with explicit constraints, and an implicit version of the Arrow--Hurwicz gradient method for convex problems dating back to the 1950s extended to nonconvex problems. We close the talk with numerical results for a class of highly nonlinear and badly conditioned control constrained elliptic optimal control problems with a semismooth Newton approach for the regularized subproblems.

ECTS: not yet determined

Lung cancer (LC) is the leading cause of death of cancer in Canada in both men and women, and indoor radon is the second leading cause of LC after tobacco smoking. The Population Attributable Risk (PAR) is used to assess radon exposure risk. We use the PAR to identify the radon levels responsible for most LC cases. During the period 2006–2009, 6% of houses in Ontario, 9% of houses in Alberta, 19% of houses in Manitoba, 7% of houses in Quebec, and 5% of houses in British Columbia had radon levels higher than 200 Bq/m3 and was responsible about 913, 211, 260, 972, and 258 lives, respectively. Radon mitigation programs could have prevented these LC cases. We use the PAR function of the two variables, radon action, and target levels, to search for a possible optimal mitigation program. The PAR is a linear function in the target radon value with an estimated slope of 0.0001 for Ontario, Alberta, Quebec, and British Columbia, and 0.0004 for Manitoba. The PAR is an increasing function in the radon action level. The PAR is sensitive to changes in the radon mitigation program and as such, any improvement is a worthwhile investment.

ECTS: 0

Tidy data is a standard way of storing your data where columns are variables and rows are observations. Tidy data, particularly when coupled with tidy tools, makes data analysis easier because you can spend less time wrangling the output of one function so that it works as the input for another. Tidy data will make your analysis easier but how you get wild-caught data into a tidy form? In this talk, I`ll discuss some of the tools that I have worked on for tidying data (e.g. the tidyr package), the limitations of those tools, and what I`m thinking about next. In particular, I`ll discuss a new approach for "pivoting" data, and discuss some of the challenges posed by data stored in hierarchical form (e.g. JSON).

Exhibition Opening "Women of Mathematics throughout Europe"
[ more ...]

Public Talk

Location: Mathematikon, Foyer, Im Neuenheimer Feld 205, 69120 Heidelberg

ECTS: not yet determined

The event is organized in close cooperation with the conference "Geometric Analysis meets Geometric Topology“.

Description:

This touring exhibition, whose starting point is the 7th ECM held in July 2016 in Berlin, stems from the observation that nowadays, women still find it difficult to embrace a career in the mathematical academic world and the disparity between the proportion of men and that of women among professional mathematicians is still shamefully large.

The thirteen women mathematicians portrayed here share with us their experience, thus serving as role models to stimulate young women scientists to trust their own strength. In presenting mathematics through women mathematicians’ perspectives and samples of their life stories, we hope to highlight the human aspects of producing mathematics, making this discipline more tangible and therefore more accessible to outsiders or newcomers.

This exhibition and the catalogue (publishing house: Verlag am Fluss) are the result of the joint efforts of the photographer Noel Tovia Matoff and four mathematicians by Sylvie Paycha, Sara Azzali, Alexandra Antoniouk, Magdalena Georgescu, with the precious help of Maria Hoffmann-Dartevelle, who translated into German and Sara Munday, who proofread the interviews and, last but not least, our two inspired graphic designers Wenke Neunast/eckedesign (exhibition) and Gesine Krüger (catalogue).

Moderne Materialien zählen zu den zentralen Zukunftsthemen in der angewandten Forschung. Die Verwendung hochmoderner Planungsprozesse in den Materialwissenschaften und bahnbrechende Entdeckungen in der Nanoforschung, in der organischen Elektronik und in der computergestützten theoretischen Chemie haben zu einer Revolution geführt. Als eine der Schlüsseltechnologien für das 21. Jahrhundert erlauben die Modernen Materialien einen zielgerichteten Einsatz in zahlreichen Anwendungsgebieten. Durch die Kombination von mehreren Eigenschaften werden immer effektivere Werkstoffe ermöglicht. So können zum Beispiel Stoffe entwickelt werden, die gleichzeitig extrem leicht aber dennoch stabil sind oder wesentlich effizienteren Energietransport erlauben.

Was ist von der Materialforschung in der nächsten Dekade an Entwicklungen noch zu erwarten? Wie wirken hier die unterschiedlichen Forschungsrichtungen zusammen? Und welche Rolle spielt die computergestützte Simulationstechnik bei diesem Paradigmenwechsel von der experimentellen Entwicklung neuer Materialien zur gezielten Planung von Materialeigenschaften am Computer? Mit diesen Fragen beschäftigt sich der 16. Modellierungstag. Wir haben Experten aus Universitäten, Forschung und Produktion eingeladen, um in Impulsvorträgen und praxisnahen Diskussionen die zentralen Fragestellungen aus diesem interdisziplinären Feld zu erörtern.

Die Veranstaltung wird von HGS MathComp und der Stadt Heidelberg organisiert sowie von der IHK Rhein-Neckar und der Industrie unterstützt.

Pioneering Structural Repair & Conservation in Angkor
[ more ...]

Talk

Speaker: John Sanday OBE, FSA
Location: Centre for Organismal Studies Heidelberg (COS), Seminar Room 00.005, INF 230, 69120 Heidelberg

ECTS: 0

John Sanday, Conservation Architect, who has spent the last 45 years working in Asia, worked for at least 20 of those years in Cambodia. Arriving for the first time in Siem Reap in 1989, he and his team pioneered the first project, the Preah Khan Conservation Training Project which was supported by the World Monuments Fund. The Khmer Rouge disturbances were still evident in Angkor as the fast-growing sub-tropical jungle, which engulfed the partially ruined monuments provided an ideal hiding place for the Khmer Rouge militia. John’s early memories were of the skirmishes still taking place on the outskirts of the historic city of Angkor and the sounds of explosions and gunfire – it was indeed a memorable start to several decades of working in one of the largest monumental cities of its time, which was later to be placed on the UNESCO World Heritage List.
John will briefly describe his early days of setting up the first major conservation training programme in the 12th Century Buddhist monastic complex. As many of you will be able to recall the time we have spent together in Angkor, I will take this opportunity to describe some of the problems we had to face and the techniques we developed in Preah Khan and three other sites in Angkor to conserve the structures with minimal intervention. There will be plenty of illustrations showing Angkor as John found it in the 1990’s and it will provide an excuse and set the background for him to side track to another Khmer style site in the far North of Cambodia.
Banteay Chhmar, one of the great Khmer sites, is closely linked to Angkor despite it being about 100km to its north. This 12th Century site, which is stylistically emulates the temples in Angkor of the Bayon period, is my link with IWR as it was the birth of an extraordinary project which Professor Georg Bock and had been fantasizing for many years trying to link heritage conservation with applied mathematics. We found a way of using ‘start of the art’ technology to digitally reconstruct a section of exquisite bas relief carvings on a stone enclosure wall which enclosed the temple complex known as Banteay Chhmar. This project need careful measurement and digital recreation of the fallen sections as the first step to their reconstruction following a highly sensitive conservation intervention to protect the decorative stone carvings. The Bas Relief Wall measures 1,400 metres in length of which 75% has collapsed.

Similarly, a free-standing sandstone tower supporting four carved images of, possibly the king or maybe the Buddha, measuring approximately 15 metres high, was threatening imminent collapse. These two different architectural elements were selected to test a system for digital re-assembly.

A section of the enclosure wall was selected. Each stone in was measured and referenced. Missing stones were located and the decorative stones were carefully dismantled and each stone was scanned. A process was also developed for the consolidation and cleaning of these masterpieces ready for reconstruction.
Drawings of the Tower were prepared referenced and carefully dismantled and each stone was scanned.
John will describe the system which IWR developed to solve “John’s Puzzle”, Khmer architect Dr. Peakdey Nguonphan and Dr. Ann from Germany headed up the team which developed the digital technology.
As a result of this multi-disciplinary research and along with support from many of the IWR teaching staff, the stones began to recognize their original positions in the structures and along with the knowledge and experience of the Khmer stone masons who had worked with us in Preah Khan, progress was made. I will explain the full process with illustrations.

Time will be allocated for questions ad discussions.

LES/Flamelet Modeling of Multi-regime Turbulent Jet Flames
[ more ...]

Talk

Speaker: Dr. Yong Hu
Location: INF 205, SR 2

ECTS: 0

Turbulent flames feature a complex multi-scale turbulence and chemistry interaction, which usually leads to the flame structure that cannot be simply categorized into the single-regime burning. The simplest burning structure of flame is in either non-premixed or premixed regime, for which two distinct modes are observed for the species transportation and reactions. However, the combustion processes are further complicated in most practical applications, for example, the liquid-fueled burner that characterizes the additional dispersed phase for fuel supply, and hence the partially premixed reaction as well as an evaporation-dominated regime. This multi-regime combustion mode is therefore more often involved and poses a challenge to the model. In this work, due to the computational efficiency, the conventional flamelet model that is originally proposed for simple premixed or non-premixed reactions is explored for use in large eddy simulation (LES) of multi-regime turbulent flames. The changes of reaction regime at sub-grid scale are dynamically described by a flame index that is developed in a way facilitating the implementation of single-regime flamelet structures. The validity of models is examined by consideration of both gas and liquid flames, which include a lifted jet flame and a piloted spray flame. Results show that although formed by different mechanism, the partially premixed reaction is predominant in the considered flames, and the present model can properly reproduce these structures. Computed data are in general good agreement with experimental profiles of temperature, species mass fraction and droplet size.

ECTS: 2

Projekte im Bildungs-, Sozial- und im Forschungsbereich dienen dazu, kurz- oder mittelfristig arbeitsplatzsichernd zu wirken und Nachwuchskräften weitere Berufserfahrung und Qualifizierungsmöglichkeiten zu bieten. Aus der Perspektive von wissenschaftlichen Einrichtungen und Hochschulen sind sie zudem erwünscht, um die Drittmittelbilanz zu stärken und somit im nationalen Leistungsvergleich der Hochschulen eine mo?glichst positive Stellung zu erreichen.

Häufig müssen Mitarbeiter/innen von Hochschulen oder Forschungsinstituten ohne entsprechende Vorerfahrung an Projektanträgen arbeiten. Möglichkeiten der hausinternen Unterstützung oder des Austausches mit projekterfahrenen Mitarbeitern/innen sind selten. Dadurch gehen wertvolle Zeit- und Personalressourcen verloren. Dieses Seminar hat deshalb zum Ziel, die Antragstellung stärker zu professionalisieren, Tipps und Tricks zu vermitteln und im Endeffekt eine höhere Erfolgsbilanz zu erzielen.

Im Seminar gehe ich mit Ihnen Schritt für Schritt die wesentlichen Aspekte der Antragsgestaltung durch und erkläre diese an Beispielen. Dabei werden auch einige Grundlagen des Projektmanagements vermittelt. Denn Fehler, die bei der Planung gemacht werden, können später zu schwerwiegenden Folgen im Verlauf des Projektes führen.
In diesem Seminar werden Problemstellungen aufgegriffen wie:
• Wie entwickle ich aus meiner Idee ein perfektes Konzept?
• Antragssprache – Antragsprosa: Einige Schreibtipps
• Wie interpretiere und verstehe ich ein Förderprogramm? Was muss ich beim Antragschreiben unbedingt berücksichtigen?
• Über den Umgang mit Gutachtern: Evaluationsprozesse, Wie wird ein Antrag gelesen? Welche Faktoren führen zu Entscheidungen?
• Wo und wie finde ich Partner und wie binde ich diese in ein Konsortium ein?
• Wie recherchiere ich nach Förderprogrammen?
• Wie passe ich meine Idee an die Vorstellungen des Förderers an?
Da jedes Programm andere Fo?rderbedingungen stellt, werde ich mich auf einige fachspezifisch passende Pro- gramme konzentrieren. Grundbedingungen und Vorgehensweise in der Antragsgestaltung sind jedoch auf alle Förderprogramme übertragbar.
Alle Projektphasen oder wichtige Themen werden in Arbeitsgruppen vertieft. Einige TeilnehmerInnen werden im Seminar Gelegenheit haben, aktiv in Arbeitsgruppen an eigenen Projektantra?gen zu arbeiten und diese mit ent- sprechendem Feedback von mir sowie den anderen TeilnehmerInnen zu einem Grobkonzept zu entwickeln. Nutzen Sie diese Chance! Bringen Sie nach Möglichkeit eine Projektidee mit, die Sie gerne zu einem Antrag ent- wickeln würden. Ich werde vorbereitend vor dem Seminar noch einen Fragebogen versenden um evtl. passende Förderprogramme recherchieren zu können.

ECTS: not yet determined

Mit der Verfügbarkeit leistungsfähiger Computer und Softwarewerkzeuge hat sich die mathematische Modellierung, Simulation und Optimierung (MSO), als zentrale Methodik des Wissenschaftlichen Rechnens, zu einer Schlüsseltechnologie entwickelt. Aktuelle Ergebnisse der MSO in der Hochschulforschung führen allerdings auf Grund befristeter Projekte oft nur zu prototypischer, nicht nachhaltiger Software. Dieses strukturelle Hindernis führt dazu, dass neue Verfahren ihr großes Potential zur Lösung der immer komplexeren Probleme in Wissenschaft, Industrie und Gesellschaft nur begrenzt entfalten. Mit der Einrichtung des durch die Carl-Zeiss-Stiftung geförderten SCSC sollen am IWR Strukturen geschaffen werden, die dieses Hindernis beseitigen und einen wirksamen Technologietransfer in inner- und außeruniversitäre Anwendungsbereiche ermöglichen.

Representation of soil water movement
[ more ...]

Talk

Speaker: Dr. Hannes Bauser
Location: Mathematikon, INF 205, Common Room

ECTS: 0

Soil water movement is a key process in ecosystem services, such as biomass production, fresh water retention, climate regulation, or water buffering and filtering. However, the quantitative description of soil water movement on all relevant scales from meters to the global scale, remains an open challenge. In this talk I focus on the meter scale, where soil water movement can still be described with the process based Richards equation. Nevertheless, the mathematical representation of soil water movement exhibits uncertainties in all model components. This means that the representation of uncertainties in each model component becomes an integral part of the model formulation. The goal is then an optimal consistent representation with minimal uncertainties. Data assimilation methods, which combine models and data, are a key tool for this task. In this talk I present an application on a real-world case. We assessed the key uncertainties for the specific hydraulic situation of a 1-D soil profile with TDR (time domain reflectometry)-measured water contents. We employed a data assimilation method, the ensemble Kalman filter (EnKF), with an augmented state to represent and reduce all key uncertainties (initial condition, soil hydraulic parameters, small-scale heterogeneity, and upper boundary condition), except for an intermittent violation of the local equilibrium assumption by the Richards equation. To bridge this time, we employed a closed-eye period, which pauses the parameter estimation and only guides the states through this time. This ensured constant parameters throughout the whole estimation, suggesting that we achieved a more consistent description and limited the incorporation of errors into parameters.

There are various reasons for studying fixed-point property of non-continuous mappings, e.g., due to errors or perturbations, original mappings lose their contractivity or their continuity, and therefore, the existence of their fixed-points is no more warranted. To counteract this problem, we present some theorems on approximate fixed-points of roughly contractive mappings and roughly continuous mappings along with illustrating examples.

Standard Markov chain Monte Carlo (MCMC) algorithms perform a stationary linear iteration on the space of probability distributions, and hence converge geometrically. Stationary linear solvers were state-of-the-art in the 1950’s, but are now considered very slow precisely because they are geometrically convergent. We show that the same polynomial acceleration methods that have been developed for linear iterative solvers may also be applied to accelerating MCMC, in certain settings.

Low-Rank Tensor Decompositions for High-Dimensional Uncertainty Quantification

Link:

ECTS: not yet determined

Uncertainty quantification and inverse problems in many variables are pressingly needed tasks, yet high-dimensional functions are notoriously difficult to integrate in order to compute desired quantities of interest. Functional approximations, in particular the low-rank separation of variables into tensor product decompositions, have become popular for reducing the computational cost of high-dimensional integration down to linear scaling in the number of variables. However, tensor approximations may be inefficient for non-smooth functions. Sampling based Monte Carlo methods are more general, but they may exhibit a very slow convergence, overlooking a hidden structure of the function. In this talk we review tensor product approximations for the problem of uncertainty quantification and Bayesian inference. This allows efficient integration of smooth PDE solutions and quantities of interest. Moreover, we can use the low-rank approximation to construct efficient proposal density in the MCMC algorithm for inverse problems. This combined MCMC method is more accurate also if the quantity of interest is not smooth, such as the indicator function of an event.

New Energy Space Modeling and Implications on Complexity of Decision Making and Control in Electric Energy Systems

Link:

ECTS: not yet determined

In this talk we present a recently-introduced multi-layered modeling framework for posing the problem of safe, robust and efficient design and control for rapidly changing electric energy systems. The proposed framework establishes dynamic relations between physical concepts such as stored energy, useful work, and wasted energy, on one hand; and modeling, simulation, and control of interactive modular complex dynamical systems, on the other. In particular, our recently introduced energy state-space modeling approach for electric energy systems is further interpreted using fundamental laws of physics in multi-physical systems, which are modeled as dynamically interacting modules.

This approach is shown to be particularly well-suited for scalable optimization of large-scale complex systems. Instead of having to use simpler models, the proposed multi-layered modeling of system dynamics in energy space offers a promising basic method for modeling and controlling inter-dependencies across multi-physics subsystems for both ensuring feasible and near-optimal operation. It is illustrated how this approach can be used for understanding fundamental physical causes of inefficiencies created either at the component level or resulting from poor matching of their interactions.

This talk is based on the recent paper by M. D. Ilic and R. Jaddivada entitled "Multi-layered interactive energy space modeling for near-optimal electrification of terrestrial, shipboard and aircraft systems”, Annual Reviews in Control, available online May 2018. The paper provides theoretical foundations for Dynamic Monitoring and Decision Systems (DyMonDS) framework envisioned as the next-generation SCADA.

The control design based on joint work with Xia Miao and R. Jaddivada for microgrids and integration of renewable resources and demand response is used as an example to illustrate potential benefits of this approach.

Finally, many open modeling, estimation and optimization challenges/opportunities using this modeling approach are discussed.

ECTS: not yet determined

?The transfers of momentum and scalars across the air-sea interface are influenced by small-scale turbulent processes. In spite of extensive existing work on the topic, our understanding of near-surface physics remains incomplete. The measurement of the small-scale dynamics very close to the rapidly moving ocean surface can be challenging! We present laboratory and field measurements of the submillimeter-scale motions in the airflow above waves. A high resolution, large field of view Particle Image Velocimetry (PIV) system was specially developed for the measurements, capable of capturing 2D velocity fields in the turbulent airflow directly above the wavy surface. The system was recently deployed on RP FLIP. Using preliminary field measurements as well as laboratory wave tank measurements, we will discuss the impact of waves on the structure of the wind stress within the wave boundary layer, and in particular how breaking and non-breaking waves influence the momentum flux_s partitioning between viscous, form drag, wave-coherent and turbulent contributions.

Spray Combustion: From a Flamelet Model to a Flamelet Theory
[ more ...]

Talk

Speaker: Prof. Hernán Olguín
Location: Mathematikon, Im Neuenheimer Feld 205, SR 10

ECTS: not yet determined

The task of formally extending the gas flamelet theory to spray flames has been only partially fulfilled and, whereas several spray flamelet models have been derived during the last decades, only few works regarding the spray flamelet equations (SFE) are available in the literature. Therefore, a degree of maturity similar to the one already achieved for gas flames has not yet been reached for spray flames. Among the remaining open issues is the closure of the SFE in mixture fraction space, which includes developing models for the Scalar Dissipation Rate (SDR) and for the different evaporation related sources appearing due to the consideration of a liquid phase.

In this presentation, recent advances in the closure of the SDR are described, which include a reformulation of the spray flamelet equations in terms of the gradient of mixture fraction instead of the SDR itself and the derivation of a transport equation for this new variable. The results are expected to help advancing towards the development of a self-contained spray flamelet theory.

Menschen machen Modelle interessant! Die immense Vielfalt von menschlichen Attributen, Verhaltensweisen oder Reaktionen sorgt aber auch dafür, dass die Modellbildung ungleich komplexer wird. Um beispielsweise einen Prozess im sozialen oder ökonomischen Leben realitätsnah abzubilden sollte ein möglichst exaktes Bild eines Menschen entworfen werden. Die Abwägung zwischen der Einfachheit eines Modells einerseits und seiner Aussagekraft andererseits stellt dabei eine der größten Herausforderungen dar. Wie gehen Modellierer sicher, dass die gewählten Ansätze nicht nur die jeweilige Forschungsfrage beantworten sondern auch allgemeine Gültigkeit besitzen?

Der Modellierungstag greift die spannende Frage nach der Bildung von „menschlichen Modellen“ auf und fördert den Austausch zwischen Forschern, Entwicklern und Anwendern. Beiträge aus unterschiedlichen Fachrichtungen liefern dazu Denkanstöße und Diskussionsgrundlagen.

This presentation will examine the possibilities of interdisciplinary historical interpretation of artwork based on the analysis of remnant artifacts of past civilizations. How can digital technology offer solutions to assess and analyse artifacts, sculptures and architecture that have been damaged through the vicissitudes of time? Digital technology also can enhance the accessibility and display of these objects and curatorial research in museums.

Dr. Marnie Feneley will present her research, past and present, which aims to reassess the out-dated Art Historical Analytical System. She will speak about new paradigms which seek to revise traditional methodologies of art historical analysis by using empirical methodology (for example, to analyse a large data set of Asian sculpture). In particular, the use of photogrammetric modeling and high-resolution immersive visualisation systems to address the traditional perceived (visual and verbal descriptive) analysis of art history along the Mercantile Maritime Route from India to China. The objective is to gain a deeper understanding of sculptural tradition, styles, religious affiliations and cultural transmissions in Asia from the 2nd - 14th century CE.

Dr. Marnie Feneley is a lecturer in Asian Studies at the University of NSW. As a post doctoral fellow, she has been researching the transmission of Buddhism from India to Southeast Asia for the "Atlas of Maritime Buddhism,” a world touring exhibition based on the compelling story of the spread of Buddhism through the seaports of Eurasia, supported by the latest archaeological evidence.
Marnie has spent over a decade researching Southeast Asian sculpture and religion. Her doctoral thesis from the University of Sydney, “The West Mebon Vi??u: style, hydraulics and political power,” will be published later this year through National University of Singapore press. Her thesis examined the famous bronze sculpture of Vi??u found in a water shrine in the middle of the West Baray at Angkor in 1936. She has amalgamated archaeological and art historical research with digital technology by reconstructing this fractured sculpture and its temple in a digital reconstruction. She is considered a pioneer in the field digital archaeology and heritage. She regularly gives invited talks at national and international forums.

ECTS: not yet determined

Studying effective properties of porous media based on simulating flows at pore scale has become a widely applied procedure during last years. Realistic structures of pores are commonly obtained by X-ray computed micro-tomography (micro-CT). In this work we consider weakly permeable samples in which a significant fraction of porosity could not be detected at a micro-CT resolution. We therefore apply an approach in which parts of samples characterized as _solids_ during micro-CT imaging are treated as permeable porous media represented with an assumed (small) permeability. Reliable estimations of permeability of ‘solid’ parts were obtained by incorporating Scanning Electron Microscopy data. This way our computational hybrid approach combines two microimaging methods of different resolutions.

Voice matters!
Speech- & Vocaltraining
How do people learn? There_s the internet, there are books, of course. But most of the information we draw on, has originally been transmitted by the human voice: We learn while we listen to others. For teaching - and for many other activities - the way people talk is therefore essential for success.
One_s own voice is the most personal way of expressing oneself, too - and much more than just a "carrier of information" while lecturing, delivering a speech or in discussions. The human voice is in fact "the social medium no. 1". To bring the message across should therefore also take the speech qualities and one_s relation to the audience into account. If one_s voice is too low, raspy or breathy - or if one just talks too fast, people will not listen - even though the content is meaningful and important.
In this workshop, participants will explore their own voice qualities and speaking potentials in order to facilitate understanding - and to bring their messages across in a more convincing way. The methods and exercises - carefully chosen for the specific conditions of scientific life - include rhetorical, linguistic and communicational elements, with video-recording and professional feedback.

ECTS: not yet determined

The European Finite Element Fair (EFEF) is an annual series of completely informal small workshops throughout Europe with equal initial conditions for each speaker. EFEF provides a platform for high-level discussions on current research on finite element approximation, in the broadest sense, of partial differential equations. Authors are encouraged to present one new idea rather than review a full research project. In this spirit, the communication of recent and new results, even not yet published, is very welcome. A few, but strict, rules apply to EFEF in order to distinguish it from existing workshops and minisymposia in the field.

Format of the Meeting:

- Speakers at EFEF are volunteers from the audience. Provided that they are present throughout the meeting, all participants are invited to talk. Potential participants are strongly encouraged to attend at least one meeting before volunteering to speak.

- Based on the number of speakers the time available will be divided into slots for the talks. The order of the speakers will be determined through random choice, by drawing names out of a hat. Speakers cannot request a specific time to talk.

- The Presentations. Bring your presentation as a pdf-file on a USB-stick. That will make life/technical support much more relaxed and easier during the conference.

- Each speaker should introduce himself or herself, the title and topic, and is expected to leave sufficient time, within the allocated time-slot, for discussion. Speakers have to prepare a talk that can be trimmed to various lengths (from seconds to 20 minutes). For a smooth meeting, the time table will be strictly enforced.

- The Book. Since EFEF 2005, a book has been available (in the Oberwolfach tradition) to record new analytical and numerical results presented during EFEF. Results can be hand-written or typeset and glued into the book.

Efficient stage-parallel time integration and tensor-product solvers for discontinuous Galerkin methods
[ more ...]

Talk

Speaker: Will Pazner
Location: Mathematikon, Seminar Room A , Ground Floor, Im Neuenheimer Feld 205, 69120 Heidelberg
Link:

ECTS: not yet determined

Implicit time integration for discontinuous Galerkin (DG) discretizations is important in the context of boundary layer flows, anisotropic, unstructured meshes, and high degree polynomial approximations. Effective preconditioning strategies are essential to the efficient iterative solution of the resulting large, sparse linear systems. In this talk, I will discuss two topics: (1) fully implicit Runge-Kutta solvers, and (2) tensor-product preconditioners for very high polynomial degrees.

(1) There are several advantages to using fully-coupled implicit Runge-Kutta schemes compared with traditional DIRK or BDF methods. However, such methods couple all of the Runge-Kutta stages, resulting in a much larger system of equations. We transform the resulting system of equations to maximize sparsity, and then develop several ILU-based preconditioners with favorable performance properties. These solvers have the additional advantage that they allow for parallelism across the stages.

(2) Furthermore, the DG method allows for arbitrary order of accuracy, according to the degree of polynomial approximation used. High-degree polynomials result in extremely restrictive CFL conditions, motivating the use of implicit solvers. We develop efficient solvers and preconditioners that exploit the natural tensor-product structure of quadrilateral and hexahedral grids in order to obtain methods with optimal computational complexity.

Mathematical modeling and numerical simulations can provide an invaluable tool for the interpretation and analysis of the circulatory system functionality, in both pathological and healthy situations. However, although many substantial achievements have been made, most of the difficulties are still on the ground and represent major challenges for the coming years.

In this talk we introduce some mathematical models of the cardiovascular system and comment on their significance to yield realistic and accurate numerical results. They include fluid-structure interaction (FSI) models to account for blood flow in compliant vessels, analysis of absorbing boundary conditions to deal with the numerical spurious reflections due to the truncation of the computational domain and the geometrical multiscale approach to simulate the reciprocal interactions between local and systemic hemodynamics. Results on the simulation of some image-based patient-specific clinical applications will also be presented.

Mathematische Modelle kommen in unserem Alltag in vielfältigen Varianten vor. Dabei spielt die Lokalisierung eine besonders wichtige Rolle: Ein abstraktes Modell wird konkretisiert, indem es mit lokalen Daten angereichert und so präzise für einen Kunden angepasst wird.

Die geografische Komponente ist vor allem in der modellgestützten Optimierung eine entscheidende Größe. Ein Beispiel mag dies verdeutlichen: Während die Fahrroutenoptimierung in nicht-geobasierten Modellen auf abstrakte Grundgrößen wie durchschnittliche Fahrtzeit von Ort zu Ort zurückgreifen muss, können in Modellen mit detaillierten geografischen Daten exakte Vorhersagen für die Fahrtdauer beim Einsatz unterschiedlicher Fahrzeuge der zur Verfügung stehenden Flotte errechnet und in die Planoptimierung eingespeist werden. Die Kopplung mit aktuellen Verkehrsdaten erlaubt sogar eine tagesabhängige Nachoptimierung und so eine noch bessere Anpassung der Fahrpläne an die realen Gegebenheiten.

Diese Verbesserungen können auch in vielen anderen Bereichen erreicht werden:

- Modellierung der Ausbreitung von Infektionserkrankungen in Abhängigkeit von regionalem Klima und Wetter
- Hochwasservorhersage auf Basis detaillierter Geländekarten
- Planung von Funknetzwerken unter Berücksichtigung von Bebauungsplänen

Der Zusammenhang zu geografischen Daten ist so offensichtlich, dass die Anbindung geografischer Informationssysteme oft selbstverständlich erscheint. Auf dem Modellierungstag wollen wir uns mit dieser Facette der Modellbildung beschäftigen und auf Schwierigkeiten bei der Modellerstellung, Risiken in der Datengenerierung und Chancen im wirtschaftlichen Einsatz eingehen. Experten aus Wissenschaft, Forschung und Praxis geben dazu Einblicke in aktuelle Projekte und neue Entwicklungen.

Difference Operators in Sobolev Spaces and Applications

Talk

Speaker: Prof. Alexander L. Skubachevskii
Location: Mathematikon, Seminar Room 12 / 5th Floor, Im Neuenheimer Feld 205, 69120 Heidelberg

ECTS: not yet determined

The theory of elliptic differential-difference equations has many interest-ing applications e.g. to
• the theory of sandwich shells and plates,
• the Kato problem concerning the analyticity of the square root of an analytic function of dissipative operators,
• nonlocal boundary value problems arising in plasma theory,
• the theory of multidimensional diffusion processes,
• nonlinear optics, …

This theory is based on the properties of difference operators acting in Sobolev spaces. Most important property of a regular difference operator:

It maps the Sobolev space of the first order with the homogeneous Dirichlet boundary condition onto the subspace of the Sobolev space of the first order with nonlocal boundary conditions continuously and bijectively. This result allows to reduce boundary value problems for strongly elliptic differential-difference equations to elliptic equations with nonlocal boundary conditions. Conversely, in some cases nonlocal elliptic boundary value problems can be reduced to elliptic differential-difference equations.

This talk will present a unifying theme among the various effects of protein charges and polar groups. Simple models will be used to illustrate basic ideas about electrostatic interactions in proteins, and these ideas in turn will be used to elucidate the roles of electrostatic interactions in protein structure, folding, binding, condensation, and related biological functions. In particular, I will examine how charged side chains are spatially distributed in various types of proteins and how electrostatic interactions affect thermodynamic and kinetic properties of proteins. Both important historical developments and recent experimental and theoretical advances in quantifying electrostatic contributions of proteins will be highlighted.

Mathematical modelling and simulation of physiological processes in organs and organisms are confronted with the challenge that the processes take place in complex structures, often on branching networks. In this lecture we consider networks arising in plants (“trees”, root-systems, vessel systems in leaves) and in vascular systems - in particular in cardio vascular systems. We are going to focus on the following topics:

1. characterization of the arising complex networks and construction of a coding system, including the essential information required in real applications;
2. requirements for the data, methods for data collection and processing;
3. algorithms to solve the geometric inverse problem to determine from CT-data the geometry and the developed code of the underlying network;
4. presentation and discussion of results obtained in recent research at IWR for the blood vessel system for the human heart, based on real CT-data;
5. open problems, requirements from the applications.

ECTS: 0

We survey our recent and ongoing work [1,2] on finite element methods for contact problems. Our approach is to first write the problem in mixed form, in which the contact pressure act as a Lagrange multiplier. In order to avoid the problems related to a direct mixed finite element discretisation, we use a stabilised formulation, in which appropriately weighted residual terms are added to the discrete variational forms. We prove that the formulation is uniformly stable, which implies an optimal a priori error estimate. Using the stability of the continuous problem, we also prove a posteriori estimates, the optimality of which is ensured by local lower bounds. In the implementation of the methods, the discrete Lagrange multiplier is locally eliminated, leading to a Nitsche-type method [3].

For the problems of a membrane and plate subject to solid obstacles, we present numerical results.

Joint work with Tom Gustafsson (Aalto) and Juha Videman (Lisbon).

The splitting of poyharmonic equations into lower-order equations is subtle as the obvious splitting requires smoothness of the solution that might not be guaranteed by the elliptic regularity of the underlying PDE. This talk introduces a new splitting based on a Helmholtz-type decomposition. This splitting does only require the natural Sobolev regularity that is given by the weak formulation. The new mixed formulation allows for standard Lagrange ansatz functions of arbitrary polynomial degree. This talk will also state a posteriori error estimates and will illustrate the new method in numerical experiments. Applications include, e.g., the biharmonic problem from plate theory.

The global flow picture for the steady Boltzmann equation is studied (jointly with Shih-Hsien Yu). The time-asymptotic analysis is based on explicit construction of the Green's function. For the resonance situation when one of the Euler characteristic speeds is near zero, there are coupling of Knudsen-type and fluid-like waves. The construction of Bifurcation and Sone Manifolds yields finite dimensional reduction of the center manifold. Fluid nonlinearity is recognized and applied to study the global flow picture.

Motion of mobile robotic systems can be based on specific motions of auxiliary internal masses inside the main body of the robot. Such robots have no outward devices, can be hermetic and operate in various environment, including tubes, vulnerable or hazardous media. Control of rigid bodies by means of internal mobile masses can be useful also for spacecraft. Control of one-dimensional and two-dimensional motions of bodies with internal masses is discussed. Optimal controls for such systems are obtained.

We focus on models which are based on partial differential equations (PDEs) with random inputs. For deterministic PDEs there are many classical analytical results and numerical tools available. The treatment of PDEs with random inputs, however, requires novel ideas and tools. We illustrate the mathematical and algorithmic challenges of UQ for Bayesian inverse problems arising from geotechnical engineering and medicine, and an optimal control problem with uncertain PDE constraints.

Fixation Probabilities under Demographic Fluctuations
[ more ...]

Talk

Speaker: Dr. Peter Czuppon
Location: Bioquant, SR 043, INF 267, 69120 Heidelberg

ECTS: 0

We consider a population consisting of two species. Each type gives birth and dies independently of the other one. Population size is regulated by intra- and interspecific competition events letting the model follow generalized Lotka-Volterra dynamics. A quantity of interest in finite populations is the probability of fixation/extinction of one type. While it has been studied broadly in the context of fixed or deterministically varying population sizes we approximate the fixation probability in populations with stochastically fluctuating sizes. In order to do so we will take the limit of weak selection, i.e. the "fitness" benefit of one type over the other is very small.

This talk is organized by “Mathematics of Life” - a special interest group of doctoral students of the HGS MathComp.

The quest for the wiring diagram of the brain
[ more ...]

Talk

Speaker: Prof. Fred Hamprecht
Location: Kirchhoff-Institute for Physics, Lecture Hall 2, INF 227
Link:

ECTS: not yet determined

Understanding the brain is an old and yet-unsolved problem. To understand the workings of a neural circuit, it is possibly required to know its structure, and almost surely necessary to know its connectivity.
After great progress in electron microscopy, several labs worldwide are milling away at animal brains and generating what will amount to petabytes of high-quality data. The resulting images are good enough for human tracers to consistently follow at least the majority of neural processes; unfortunately, humans would take thousands of years to complete the task for even the smallest mammalian brain.
So the quest is on for computer vision algorithms to do the same automatically and reliably. The current state of the art pipelines recur to deep neural networks and combinatorial graph partitioning problems. The former are notoriously ill understood, the latter still expensive to solve at scale.
In this talk, I will sketch the problem, a state of the art approach (which does not quite achieve human accuracy yet), and I will lay out some of the open problems in the field.

Interdisciplinary Seminar Series "Structures & Mathematics":

The workshop-seminars aim at initiating interactions between mathematicians and researchers from other sciences.

Consider a rigid body that is fully submerged in a viscous fluid whose motion is governed by the Navier-Stokes equations.
I will discuss the asymptotic structure at spatial infinity of a steady flow around the body. In the 3D irrotational case, this classical problem has been almost fully resolved over the years, but many questions are still open in the 2D case. Indeed. the asymptotic structure of a 2D Stokes flow is closely related to the Stokes Paradox. In my talk, I will focus on bodies that are rotating with a constant angular velocity and discuss some new results for rotating planar flows.

Hyperbolic Approximation of the Vlasov equation and Kinetic approximation of non-linear hyperbolic systems
[ more ...]

Talk

Speaker: Laurent Navoret
Location: Mathematikon, Seminar Room 11, Im Neuenheimer Feld 205, 69120 Heidelberg
Link:

ECTS: not yet determined

In this talk, we will give an overview of different numerical methods we propose to carry out efficient numerical simulations of the kinetic Vlasov equation and for non-linear hyperbolic equations. The Vlasov equation is a kinetic transport equation in the position-velocity phase space. The numerical resolution of the Vlasov equation requires large computational resources combined with high accuracy for capturing the small scale dynamics (phase-space filamentation, gyrokinetic turbulence). By performing a finite-element semi-discretization in the velocity variable, we approximate the Vlasov equation by a hyperbolic system. Applying mass-lumping techniques on the resulting system, the approximate Vlasov equation reduces to several coupled transport equations. We consider either semi-Lagrangian method on Cartesian meshes or Galerkin-Discontinuous solver on multi-patch structured meshes to achieve high order accuracy in space. As an inverse strategy, we approximate non-linear hyperbolic equations by linear kinetic transport equations with a finite set of velocities and stiff relaxation (Lattice Boltzmann Method). Implicit resolution of the transport equations (by front tracking), combined with palindromic composition method in time (of order 2, 4 or 6) enables us to use large CFL numbers while being well adapted to parallelization.
In this talk I will give a basic introduction to multilevel Monte Carlo methods applied to uncertainty quantification problems in PDE applications. I will aim the talk at numerical analysts and computational scientists, familiar with numerical methods for partial differential equations. I will only assume basic knowledge of probability theory. A particular focus will be the study of the inverse problem, where PDE models with random coefficients that encapsulate the prior knowledge about the coefficient distribution are coupled with measurement data of functionals of the PDE solution. The talk will focus mainly on methodology, but I will refer to some theoretical results that underpin the new methods, as well as stress some open theoretical and computational problems.

Computational modeling has become more and more important in the life sciences. One important class of models are compartment models and ordinary differential equations are widely used to describe the time evolution of the model_s components in a deterministic way. This compact course will introduce stochastic compartmental modeling. The objectives of the course are to learn a) methods that allow to simulate stochastic models and b) which effects so called intrinsic stochasticity can have on systems_ dynamics. These effects will make it evident that specific calibration techniques are needed in order to be able to cope with stochastic effects and exploit their information. The course will c) give a flavor of how calibration can be performed. Time will also be devoted to let the participants learn d) when stochastic modeling is necessary and beneficial.
This course will consist of lectures as well as practical exercises. Therefore, participants are encouraged to bring laptops (please contact me in case laptop sharing is desired). There is no prior software or programming experience necessary.

What is Non-Linear Preconditioning?

IWR Colloquium

Speaker: Prof. Martin Gander
Location: Mathematikon, Conference Room / 5th Floor, Im Neuenheimer Feld 205, 69120 Heidelberg
Link:

ECTS: not yet determined

The idea of preconditioning iterative methods for the solution of linear systems goes back to Jacobi (1845), who used rotations to obtain a system with more diagonal dominance, before he applied what is now called Jacobi_s method. The preconditioning of linear systems for their solution by Krylov methods has become a major field of research over the past decades, and there are two main approaches for constructing preconditioners: either one has very good intuition and can propose directly a preconditioner which leads to a favorable spectrum of the preconditioned system, or one uses the splitting matrix of an effective stationary iterative method like multigrid or domain decomposition as the preconditioner.

Much less is known about the preconditioning of non-linear systems of equations. The standard iterative solver in that case is Newton_s method (1671) or a variant thereof, but what would it mean to precondition the non-linear problem? An important contribution in this field is ASPIN (Additive Schwarz Preconditioned Inexact Newton) by Cai and Keyes (2002), where the authors use their intuition about domain decomposition methods to propose a transformation of the non-linear equations before solving them by an inexact Newton method. Using the relation between stationary iterative methods and preconditioning for linear systems, we show in this presentation how one can systematically obtain a non-linear preconditioner from classical fixed point iterations, and present as an example a new two level non-linear preconditioner called RASPEN (Restricted Additive Schwarz Preconditioned Exact Newton) with substantially improved convergence properties compared to ASPIN.

ECTS: 0

The human brain has a complex geometric structure consisting of white and gray matter, blood vessels, ventricles, skull etc. It forms a highly anisotropic medium. Glioma in the brain are known to invade along white matter tracks and along other brain structures. Using diffusion tensor imaging (DTI) it is now possible to obtain directional information of the brain geometry. In my talk I will show how this DTI information can be used to parametrize a fully anisotropic diffusion equation for glioma spread. We validate the model on clinical data of glioma patients and discuss the future use in treatment design. (joint work with A. Swan, K.J. Painter, C. Surulescu, C. Engwer, M. Knappitsch, A. Murtha).

ECTS: not yet determined

Although half a decade has passed since Frank Rosenblatt_s original work on multi-layer perceptrons, modern artificial neural networks are still surprisingly similar to his original ideas.

In this talk I will give a brief introduction on deep neural networks and will question one of their most fundamental design aspects. As networks have become much deeper than had been possible or had even been imagined in the 1950s, it is no longer clear that the layer by layer connectivity pattern is a well-suited architectural choice. In the first part of the talk I will show that randomly removing layers during training can speed up the training process, make it more robust, and ultimately lead to better generalization. We refer to this process as learning with stochastic depth -- as the effective depth of the networks varies for each minibatch. In the second part of the talk I will propose an alternative connectivity pattern, Dense Connectivity, which is inspired by the insights obtained from stochastic depth. Dense connectivity leads to substantial reductions in parameter sizes, faster convergence, and further improvement in generalization. Finally, I
will show examples of problems that were considered challenging but have become surprisingly easy in the light of deep learning.

The Center for Digital Research in the Humanities (CDRH) at the University of Nebraska-Lincoln (UNL) - founded in 2005 - was one of the earliest Digital Humanities (DH) centers in the world, and is supported by the University as a Center of Excellence as well as by private funds and grants. The Center is a founding member of centerNet, an international network of digital humanities centers, and is an institutional member of the TEI Consortium, the National Humanities Alliance, and the National Humanities Alliance. While the Center’s roots are in Library Science and English, the mission of CDRH is to promote collaborative and transdisciplinary digital humanities research. The Center houses over fifty scholarly projects ranging in scale, topic, and purpose. In the first part of the talk, I will present an overview of these diverse projects, some of their challenges, and their wide-spread impact in the humanities and beyond.

In the second half, I will focus specifically on Digital Cultural Heritage (DCH). Recent DH cluster hires in Anthropology, Classics & Religious Studies, History, and Art & Art History at UNL are facilitating innovative research in DCH. In particular, CDRH scholars are applying and developing Geographic Information Systems (GIS), 3D Modeling, and Virtual Reality (VR) methods and tools to foster new avenues of scholarly research. Underlying much of this research is the need to unite quantitative and qualitative data—requiring new computational methods and 3DGIS tools. I will present some of my experiences, outcomes, and ongoing challenges for three DCH projects — MayaArch3D (2009-2015), MayaCityBuilder (2016-present), and Keeping Data Alive (2017-present) - situating them within the larger framework of Digital Humanities.

Biography:
Heather Richards-Rissetto is an archaeologist specializing in the ancient Maya of Central America. She is Assistant Professor in Anthropology, a Faculty Fellow in the Center for Digital Research in the Humanities (CDHR), and holds a Courtesy Appointment in the School of Natural Resources (SNR) at the University of Nebraska-Lincoln. She received her Ph.D. in Anthropology from the University of New Mexico and her undergraduate degree in Anthropology and Geography from the University of Southern Maine. She uses Geographic Information Systems (GIS) and 3D visualization to investigate how the accessibility and visibility of architecture communicated information and structured social experience and sent political and ideological messages in past societies. She is the Director of the MayaCityBuilder Project that uses procedural modeling for 3D Visualization, Analysis, and Discourse on Ancient Maya cityscapes. The MayaCityBuilder Project builds on the data and results of the MayaArch3D Project (2009-2015) — of which she was the GIS Director.

I will present a survey of the main results about first and second order models of swarming where repulsion and attraction are modeled through pairwise potentials. We will mainly focus on the stability of the fascinating patterns that you get by random particle simulations, flocks and mills, and their qualitative behavior. Qualitative properties of local minimizers of the interaction energies are crucial in order to understand these complex behaviors. Compactly supported global minimizers determine the flock patterns whose existence is related to the classical H-stability in statistical mechanics and the classical obstacle problem for differential operators.

Cell nuclei are not always spherical; some are highly irregular. The structural basis for this multiplicity of shapes appears to derive from the components of the nuclear envelope and their interactions with cytoskeletal elements. Describing these shapes mathematically is a challenge; explaining their biochemical origin remains a mystery. The goal of this seminar is to discuss aspects of these problems and to provoke comments and ideas from the audience.

Gene expression occurs in an environment in which both stochastic and diffusive effects are significant. Spatial stochastic simulations are computationally expensive compared to their deterministic counterparts and hence little is currently known of the significance of intrinsic noise in a spatial setting. I will show how starting from the reaction-diffusion master equation (RDME) describing stochastic reaction-diffusion processes, we can derive closed-form expressions for the approximate steady-state mean concentrations which are explicit functions of the dimensionality of space, rate constants and diffusion coefficients. These are generally different from those given by the deterministic theory of reaction-diffusion processes, thus highlighting the importance of intrinsic noise. Our theory is confirmed by comparison with stochastic simulations, using the RDME and Brownian dynamics, of two models of stochastic and spatial gene expression in single cells and tissues. Lastly, time permitting, I will discuss how one can extend these results to stochastic spatial simulations of intracellular processes which take into account macromolecular crowding, namely the volume exclusion due to the finite size of molecules.

Discussion with the speaker after the talk (at around 12:00), coffee will be provided.

Music Information Retrieval - When Music meets Computer Science

IWR Colloquium

ECTS: not yet determined

Significant digitization efforts have resulted in large music collections, which comprise music-related documents of various types and formats including text, symbolic data, audio, image, and video. In the field of music information retrieval (MIR) great efforts are directed towards the development of technologies that allow users to access and explore music in all its different facets. For example, during playback of some CD recording, a digital music player may present the corresponding musical score while highlighting the current playback position within the score. On demand, additional information about melodic and harmonic progression or rhythm and tempo is automatically presented to the listener. A suitable user interface displays the musical structure of the current piece of music and allows the user to directly jump to any key part within the recording without tedious fast-forwarding and rewinding. In this talk, I discuss a number of current research problems in the field of music information retrieval and indicate possible solutions. One fundamental problem is to decompose a given music signal into semantically meaningful components. To guide the decomposition, one may exploit additional information, either in the form of specific acoustic properties of the components or in the form of additional score information. As an example, I show how to compute a notewise decomposition of a music signal by applying a score-informed variant of non-negative matrix factorization (NMF). Finally, I discuss various audio editing and manipulating applications to highlight the potential of these decomposition techniques.

We consider the question of when delay systems, which are intrinsically infinite dimensional, can be represented by finite dimensional systems. Specifically, we give conditions for when all the information about the solutions of the delay system can be obtained from the solutions of a finite system of ordinary differential equations. For linear autonomous systems and linear systems with time-dependent input we give necessary and sufficient conditions and in the nonlinear case we give sufficient conditions. The ideas and results are illustrated by models for infectious diseases and physiologically structured populations.

ECTS: not yet determined

To fully utilise computational resources for applications based on Discontinuous Galerkin discretisations, efficient and algorithmically optimal implementations are necessary. Traditionally a given PDE is solved by assembling a system of sparse equations and inverting the resulting matrix equation algebraically, for example with an AMG method. However, on modern multicore chip architectures with a poor FLOP-to-bandwidth ratio this approach becomes very expensive. Let N denote the number of unknowns per element. To apply the operator, in each grid cell a matrix of size N x N has to be loaded from memory and a dense matrix-vector multiplication with low arithmetic intensity is carried out; the overall cost of the method is O(N^2). This cost is reduced by matrix-free implementations where the matrix is re-calculated on-the fly. For tensor-product elements in d dimensions sum factorisation techniques reduce the computational complexity from O(N^2)=O(n^{2d}) to O(d*n^{d+1}), where n is the number of unknowns in one direction.

In preconditioned Krylov-subspace solvers and multigrid smoothers it is often necessary to invert block-diagonal matrices. Even though the action of A is implemented in a matrix-free way, local block-matrices D_e of size n^d x n^d are assembled in each cell and then inverted with an exact LU- or Cholesky-factorisation. Overall this requires O(n^{2d}) bandwidth-bound operations and quickly becomes the bottleneck of the solver as the order n increases. To circumvent this problem, we solve the system D_e.x=y approximately with an iterative method. Since the application of D_e can be implemented in a matrix-free way, the action of D_e^{-1} becomes FLOP bound and the cost decreases from O(n^{2d}) to O(n_{iter} * d * n^{d+1}) where n_{iter} is the number of iterations required to solve the system in each cell.

We study the efficiency of this approach for the solution of linear convection-diffusion systems; problems of this type arise, for example, in operator splitting approaches for unstable porous media flow. We demonstrate the algorithmic and computational efficiency of the method for a hybrid multigrid algorithm with hp-coarsening, similar to [Bastian et al. (2012), Num. Lin. Alg. with Appl. 19 (2), pp. 367-388]: on the finest level a matrix-free block-Jacobi or block-SSOR smoother is applied to the high-order system, and the low-order system on the coarser levels is solved with AMG.

All code is implemented in the EXADUNE code base and we demonstrate the efficiency of our approach for a range of elliptic PDEs, including a convection-dominated problem and the stationary SPE10 benchmark.

The flows in close proximity to the air-sea interface control the exchanges between the atmosphere and the ocean, such as gases, heat, vapor, and momentum. The scales of the flow motions, including surface waves and turbulence, are much smaller than that of the atmosphere and the ocean. The processes within this surface layer, however, can profoundly affect the large-scale geophysical flows. The topic has been studied mainly by experimental measurements in the field and laboratory. Numerical simulation provides a complementary tool to reveal the underlying physics, but also pose challenges to the computations due to the inherent nonlinearity of the free boundary and the distinct length/time scales in the turbulent flow and wave motions. In this talk, I will briefly review the numerical method we have developed to solve this free-boundary problem. I will then present recent progress in evincing new physics in microscale air-sea interaction using numerical simulation. These studies are either aimed to elucidate previously unexplained observations or motivated/inspired by the recent innovative measurements.

Simple mathematical models for personalized oncology

Location: Mathematikon (INF 205) Konferenzraum (5th floor)

ECTS: not yet determined

Mathematical models of tumor dynamics have become more accurate and accepted in recent years and enable a better prediction of initiation and development of a tumor, as well as its response to therapy. Using models one can compare different approaches or design new treatment strategies, which then can be tailored to individual patient data.

I will present some simple mathematical models for different problems in oncology; preventive gastric cancer screening, head and neck cancer response to radiation therapy, and combination therapies for pancreatic cancer. Mathematical models will be fit to retrospective clinical training data to derive parameter distributions for each participating mechanism. Parameter distributions with small variation will be collapsed into uniform rate constants, leaving variable mechanisms that are most likely to determine patient-specific outcomes. Calibrated models will be validated on independent training data, before virtual "in silico" trials determine optimal treatment protocols on a per patient basis.

Additional information:
After the talk there will be a meetup with the speaker to discuss different subjects in the area of cancer modelling. Discussion topics will include the impact of mathematical and computational models in the clinic, the challenges of interdisciplinary collaboration, and the current hot research topics. The meetup is tailored to provide a relaxed atmosphere where graduate students can have an introspect discussion of the field. Dr. Enderling will also address questions such as:
- What would you have wanted to know when you started working in this field?
- What are the "dos" and "don_ts" for PhD students starting their research in this field?
Master and PhD students are highly encouraged to attend.

Location: Computing Center of Heidelberg university

ECTS: not yet determined

In this tutorial we present an asynchronous data flow programming model for Partitioned Global Address Spaces (PGAS) as an alternative to the
programming model of MPI. GASPI, which stands for Global Address Space Programming Interface, is a partitioned global address space (PGAS) API.
The GASPI API is designed as a C/C++/Fortran library and focused on three key objectives: scalability, flexibility and fault tolerance. In
order to achieve its much improved scaling behaviour GASPI aims at asynchronous dataflow with remote completion, rather than
bulk-synchronous message exchanges. GASPI follows a single/multiple
program multiple data (SPMD/MPMD) approach and offers a small, yet
powerful API (see also www.gaspi.de and www.gpi-site.com). GASPI is successfully used in academic and industrial simulation applications.
Hands-on sessions (in C and Fortran) will allow users to immediately test and understand the basic constructs of GASPI. This course provides
scientific training in Computational Science, and in addition, the scientific exchange of the participants among themselves.

Please note that for the excercises the user needs to bring an own laptop and to already have access to either the bwUniCluster [1] oder the bwForCluster MLS&WISO Production [2] in Heidelberg/Mannheim. Please notify us in case of any problems. The course language is German (the slides are in English) or English if required.

In this talk, we address several aspects of model and cost reduction techniques for the numerical simulation of PDEs. Firstly, we consider tearing and interconnection strategies in combination with interface models and reduced basis methods. These techniques are of special interest in the case of vibro-acoustic simulation and can largely reduce the number of degrees of freedom. Numerical results in case of orthotropic material laws are given for a violinbridge as well as a timber building.
Secondly, we discuss surrogate models which aim at a complexity reduction. Here we introduce locally mass conservative scheme in a local postprocessing step as well as adaptive control techniques for resilient multigrid solvers. In all cases, we provide the numerical analysis, algortihmic aspects and illustrative large scale results.

Interior point methods are well-suited for solving multistage stochastic
NLPs when an efficient algorithm for the huge structured KKT systems is
available. This is the case for large scenario trees with a moderate
number of variables per node: we present a distributed ``tree-sparse__
solution algorithm based on a static partitioning of the tree and
featuring low memory and communication overheads. We also address
structured quasi-Newton updates for the sparse Hessian as well as
structured inertia corrections to address non-convexity or
rank-deficiency of the KKT system.
Computational results for benchmark problems from portfolio optimization
and robust model predictive control demonstrate the performance of our
approach.

Method of multiple shooting for computing shortest descending paths on convex terrains

ECTS: not yet determined

Given a polyhedral terrain and two points p, q on the terrain, a path joining p to q on the terrain is descending if the z-coordinate of a point v never increases while we move v along the path from p to q. The problem of finding shortest descending paths joining two given points on a polyhedral terrain was posed first by de Berg and van Kreveld (in Algorithmica, 18 (1997), pp. 306-322). Recently, the problem of finding approximations of such paths is considered by Ahmed, Lodha, and Lubiw (2010), Wei and Joneja (2013), Cheng and Jin (2014), etc. using Steiner point, graph, and sequence tree techniques.

In this talk we introduce the method of multiple shooting for solving the problem. It includes the factors: (f1) partition of the terrain, (f2) the straightness condition for the shortest descending paths at shooting points, and (f3) update of shooting points. In particular, the method does not rely on Steiner point, graph and sequence tree techniques on the entire terrain. If the straightness condition is satisfied then we obtain a local shortest descending path.

The corresponding algorithm is implemented in C++ using CGAL. Numerical results nonetheless indicate that the result is close to a local shortest descending path, even if it does not fulfil the straightness condition.

Dimension reduction or feature selection is an effective strategy to handle contaminated data and to deal with high dimensionality while providing better prediction. To deal with outlier proneness and spurious variables, we propose a method performing the outright rejection of discordant observations together with the selection of relevant variables.
To solve this problem, it is recasted as a mixed integer program which allows the use of efficient commercial solver. Also we propose an alternate projected gradient algorithm (proximal) so get a nice appoximated solution.

ECTS: 6

Machine Learning is the science and art of extracting meaningful information from data. In supervised machine learning, we use a training set of annotated examples to teach a computer to make valid predictions, or to reliably recognize items. In unsupervised learning, we use computers in an exploratory fashion, to discover interesting patterns in data.

Machine learning and pattern recognition are currently taking center stage in applications ranging from autonomous driving to social network analysis and drug development.

This seminar covers the essential techniques typically taught in an introductory lecture, including

statistical learning theory
generative and discriminative classifiers
ridge regression, lasso
logistic regression, generalized linear models
kernel methods, support vector machine
perceptron, multi-layer perceptron, neural networks
dimension reduction
cluster analysis

Mathematical modeling and numerical analysis for incommensurate 2D materials
[ more ...]

Talk

Speaker: Prof. Mitchell Luskin
Location: Mathematikon, Konzerenzraum 5.OG
Link:

ECTS: 0

The unique electronic, optical, and mechanical properties of 2D materials have sparked an extraordinary level of theoretical and experimental activity. Stacking a few layers of 2D materials such as graphene and molybdenum disulfide, for example, opens the possibility to tune the electronic and optical properties of these materials. One of the main issues encountered in the mathematical and computational modeling of layered 2D materials is that lattice mismatch and rotations between the layers destroy the periodic character of the system.

Even basic concepts like the Cauchy-Born strain energy density, the electronic density of states, and the Kubo-Greenwood formulas for transport properties have not been given a rigorous analysis in the incommensurate setting. New approximate approaches will be discussed and the validity and efficiency of these approximations will be examined from mathematical and numerical analysis perspectives.

"Feedforward and feedback learning in sensorimotor control"
[ more ...]

Talk

Speaker: Dr. David Franklin
Location: Seminar Raum A im Mathematikon Bauteil A

ECTS: not yet determined

The human sensorimotor control system has exceptional abilities to perform skilful action despite ever changing conditions. I will discuss
how this adaptability can result through intrinsic feedback mechanisms in two different ways: sensory feedback driving feedforward adaptation;
and feedforward adaptation in turn adapting the feedback responses and tuning them to the environment. In the first part of my talk I will
examine how prior sensorimotor cues can be used to learn independent motor memories. These results suggests that motor memories are encoded
not simply as a mapping from current state to motor command but are encoded in terms of the recent history of sensorimotor states. However
learning can also be used to adjust intrinsic feedback control. The second half of my talk will focus on a few recent studies examining
feedback responses; demonstrating both how they are modulated for control and using them to probe the underlying mechanisms of visually
guided reaching. Finally I will present work demonstrate that the visuomotor feedback gain shows a temporal evolution related to task
demands (as predicted by optimal control) and that this evolution can be flexibly recomputed within 100 ms to accommodate online modifications to
task goals.

Root Functions: A Special Class of Boolean Functions
[ more ...]

Talk

Speaker: Professor Debesh K. Das
Location: Mathematikon, Seminar Room SR 10 / 5th Floor, Im Neuenheimer Feld 205, 69120 Heidelberg

ECTS: not yet determined

The talk introduces a special class of Boolean functions known as root functions. We show that there exists such class of Boolean functions, which can never appear as faulty response in irredundant two-level AND-OR combinational circuits even when any arbitrary multiple stuck-at faults are injected. Conversely, we show that any other Boolean function can appear as a faulty response in an irredundant realization of some root function under certain stuck-at faults. We characterize this new class of functions and explore their different properties. We show that for n variables, their number is exactly equal to the number of independent dominating sets in a Boolean n-cube. Also, we show that an n-variable root-function with minimum number of true minterms, where n = 2k - 1; k > 2, possesses some inherent error detection/correcting properties.

Dr. Debesh K. Das received the B.E. and M.E. degrees in electronics and telecommunication engineering and the Ph.D. degree in Engineering from Jadavpur University, Calcutta, India. He is currently with the Department of Computer Science and Engineering, Jadavpur University, as a Professor. Prior to this, he served as Minister-in-Charge of Information Technology in the Govt. of West Bengal. His research interests include logic synthesis and testing of VLSI circuits and fault-tolerant computing. He has published more than 100 papers in reputed Journals and International Conference Proceedings.

Interdisciplinary Seminar Series "Structures and Mathematics“: Neuronal ensembles as elementary representations in the nervous system
[ more ...]

Public Talk

Speaker: Prof. Dr. med. Andreas Draguhn
Location: Mathematikon, Lecture Hall / Ground Floor, Im Neuenheimer Feld 205, 69120 Heidelberg
Link:

ECTS: not yet determined

Studies of the nervous system are performed at multiple system levels, beginning with the structure and function of single molecules (e.g. ion channels), electrochemical processes at the level of single cells (e.g. generation of action potentials, synaptic transmission), activity in multi-neuronal networks (e.g., processing of visual inputs in the retina), large-scale spatiotemporal patterns in the nervous system (e.g., brain-wide activation patterns during cognitive task performance) and, ultimately, at the cognitive-behavioral level of the whole organism (perception, motion, decision making, emotions etc.). In real live, processes at all these levels work together, such that simple bottom-up or top-down models of brain function are far too simple.

This complexity is one of the reasons why mathematical approaches are indispensable in modern neuroscience. We are dealing with highly parallel data, e.g. simultaneous recordings from multiple neurons in electrophysiology, or from millions of volume elements in functional brain imaging. In addition, the emergent properties of complex systems like neuronal networks cannot be simply predicted from linear causal relations and, thus, are often inferred from computer simulations. Third, we are beginning to reveal more and more structural details of the brain – the functional consequences of these boundary conditions are again a topic for mathematicians and network scientists.

In my presentation, I will exemplify some major research problems and approaches of modern neuroscience, focusing on the level of neuronal networks. Our leading question is: How does the brain represent a perception, a memory, a planned action or a motor program? Most neuroscientists agree that this ‘coding’ is performed by multiple cells which are co-activated in a reproducible manner. These sets of neurons are called ensembles or, in other research traditions, assemblies. They can be reproducibly activated even by incomplete input patterns, forming stable spatio-temporal structures or (in one specific approach) attractors in the network’s state-space. In most cases, activation of ensembles happens on top of synchronous network oscillations which provide a temporal scaffold (or ‘clock’) for coordination of the multi-neuronal activity pattern.

In this presentation, we shall discuss the concept of ensembles and its implications for the multiplicity, stability and plasticity of different representations. We will highlight some specific questions based on own and other’s data, mainly from memory-forming networks in the rodent hippocampus. Key questions are: What are the key properties of hippocampal ensembles? How are single neurons bound into reproducible spatiotemporal patterns? How are non-participating neurons reliably suppressed during activation of a given ensemble? How are local ensembles bound into large-scale functional networks?

All of these questions require multidisciplinary approaches including cell and systems physiology, behavioral neurosciences and, importantly, advanced data analysis and mathematical modelling. The importance of (and sometimes lack of) generally accepted quantitative models of neuronal networks, their cellular constituents and their large-scale effects will become clear from each of the multiple open questions mentioned during the presentation.

Math Goes Public lectures address a wide audience in natural and social sciences and engineering: They show how Mathematics helps explaining many different phenomena. I present dew drops on spider webs, a beautiful example for nonlinear problems. In these problems different components inter react, defining one of the most fascinating areas of modern Mathematics. Locally like linear problems, fascinating unexpected scenarios of new critical solutions with new properties do occur: The original symmetry or stability of solutions gets lost, called symmetry or stability breaking bifurcation with structural consequences. Why are only lines of drops observed along spider threads? We present the essential aspects of a mathematical model with very interesting mathematical challenges and the corresponding numerical methods yielding some plots. This complicated problem has never been studied before. In Marburg Karlheinz Schild, Bernhard Schmitt and I made it.

HGS MathComp Ladyshenskaya Lecture

Although in nature there is nothing really unbounded problems for partial differential equations in unbounded domains are often used to model certain geometries. Thereby the behavior at infinity of the solutions plays an important role in the modeling process. For elliptic problems, including the stationary Stokes system in particular, a broad theory exists for various kinds of unbounded domains. There results on spatial asymptotics typically appear as a decomposition of the solution into explicitely known terms and a remainder with corresponding estimates. In contrast to this very little is known about time dependent problems. Here we consider time periodic solutions to the Stokes problem in a layer where the data are also time periodic and smooth with bounded support for simplicity.

We will look at progress in Linear Programming (LP) and Mixed Integer Programming (MIP) software over the last 25 years. As a result of this progress, modern LP codes are capable of robustly and efficiently solving instances with multiple millions of variables and constraints.

With these LP advances as a foundation, MIP provides the modeling framework and the key solution technology behind prescriptive analytics. The performance improvements in MIP codes have been nothing short of remarkable, well beyond those of LP, and have transformed this technology into an out-of-the box tool with an almost unlimited range of real-world applications.

Interactive physics-based simulations are now capable of reproducing a growing number of motion skills, often with a focus on generating agile-and-robust locomotion. In this talk, I review recent progress in simulation-based models of human and animal motion as used for computer animation, where they seek to replace simpler kinematic models based on motion-capture.

We will discuss the roles of optimization, machine learning, and simplified models in these approaches, as well as what insights might be shared between robotics and our simulation-based work in animation. A wide variety of animated results will be shown to illustrate the capabilities of current methods. I_ll also identify several research directions where we still need to see significant progress.

ECTS: not yet determined

Perception is a key component of every intelligent system as it enables actions within a changing environment. While humans perceive their environment with seemingly little efforts, computers first need to be trained for these tasks. One of the biggest challenges in computer vision are ambiguities which arise due to the complex nature of our environment and the information loss caused by observing two-dimensional projections of our three-dimensional world. In this talk, I will present several recent results in stereo estimation, 3D reconstruction and motion estimation which integrate high-level non-local prior knowledge for resolving ambiguities that can´t be resolved using local assumptions alone. Furthermore, I will discuss the "curse of dataset annotation" and present a method for augmenting video sequences efficiently with semantic information.

Die quantitative Strategie bedeutet: mehr schlechte Bewerbungen schreiben. Sprich: einfach mehr flirten in der Hoffnung, dass auch ein blindes Huhn mal ein Korn findet.
Die qualitative Strategie verspricht, durch eine kluge Bewerbung und souveränes Auftreten in den Gesprächen mehr Erfolg zu haben. Das bedeutet beim Bewerben wie beim Flirten: mehr Auswahl. Um letztere Strategie dreht sich das Seminar.

Inhalt:
-Was unterscheidet eine gute von einer schlechten Bewerbung?
-Wie denkt der Personaler?
-Das Vorstellungsgespräch aus beiden Perspektiven beleuchtet.
-Die typischen Stressfragen und die typischen Fehler des Bewerbers.
-Wie viel Gehalt kann ich verlangen?

Nach dem Seminar werden die Teilnehmer:
-Bessere Bewerbungen schreiben können.
-Mehr Einladungen zu Vorstellungsgesprächen haben.
-Im Vorstellungsgespräch punkten und aus der Masse hervorstechen.
-Im Stressinterview unter Druck gelassen bleiben.
-Gekonnt die Gehaltsfrage klären.

Krylov subspace methods, their analysis and applications
[ more ...]

Compact Courses

Speaker: Prof. Zdenek Strakos
Location: IWR, Room 520, Im Neuenheimer Feld 368, 69120 Heidelberg

ECTS: 2

Krylov subspace methods are widely used for solving linear algebraic systems, approximating eigenvalues, and model reduction in science and engineering. This course will give a short overview of their mathematical foundations.

First, Krylov subspace methods use linear projections onto a sequence of finite dimensional subspaces. Since these subspaces are formed using repeated applications of the given matrix (operator) to a given initial vector, the methods are highly nonlinear. In fact, the nonlinearity allows for adaptation of the computation to the problem, which often results in an expected acceleration of convergence. If no substantial acceleration occurs and the results of the computation can be described using linear contractions, then one should ask whether the chosen Krylov subspace method is efficient for solving the given problem. The strong nonlinearity poses significant challenges for the analysis of the methods as well
as the understanding of effects of finite precision arithmetic in practical computations.

Different mathematical viewpoints and the resulting tools are used for analysis of Krylov subspace methods.The methods are closely linked with matching moments model reduction and quadrature. Spectral properties (eigenvalues and eigenvectors) of the matrix, together with the projections of the initial vector on the individual invariant subspaces, describe the convergence behavior, provided that the individual spectral invariant subspaces are mutually orthogonal. The general case is intriguing and still
far from being fully understood. Numerical stability of Krylov subspace methods is closely linked with the loss of orthogonality of the computed generating vectors, which is governed by different mechanisms for methods using short and long recurrences.

Finally, it is beneficial to consider formulations of Krylov subspace methods in infinite dimensional Hilbert spaces. That naturally leads to the concept of operator preconditioning. Preconditioning is a crucial part of computations using Krylov subspace methods; in most cases it is based on algebraic considerations and the discretized system of equations. Therefore it could be of interest to make a link between the operator and algebraic preconditioning.

The course will end with discussion of open questions.

Im Rahmen des Forschungsprojekts "Textdatenbank und Wörterbuch des Klassischen Maya" wird derzeit eine maschinenlesbare Annotation der Hieroglyphentexte auf der Grundlage von XML TEI konzipiert und entworfen. Ziel des strukturierten Markups der Mayaschrift ist es die Struktur der Originalschreibung und die Anordnung der Zeichen im Text möglichst genau mit Hilfe von TEI XML abzbilden. Bei partiell entzifferten Mayaschrift kommt das Problem hinzu, dass anstelle von Transliterationen und Transkriptionen unentzifferte Zeichen oder Textstellen mit Hilfe von Codes und Nomenklaturen wiedergegeben werden müssen um auf dieser Grundlage fragliche Zeichen in ihrem jeweiligen Verwendungskontext zu dokumentieren. Die Dokumentation der Originalschreibung ist grundlegend für die epigraphische Arbeit mit syllabischen und logo-syllabischen Hieroglyphen- und Keilschriftsystemen. Unser Projekt hat hier ein Desiderat für die vergleichende Schriftforschung erkannt und möchte in Zusammenarbeit mit Experten für kompexe Schriftsysteme Lösungen auf der Grundlage von XML TEI und Epidoc erabeiten. Im Rahmen des Vortrags in Heidelberg stellen wir die Probleme und Herausforderungen bei der Annotation der Mayaschrift vor.

Die nur teilweise entzifferte Hieroglyphenschrift und Sprache der Mayakultur steht im Mittelpunkt eines Forschungsprojektes der NRW Akademie der Wissenschaften, das in Kooperation zwischen den Universitäten Bonn und Göttingen durchgeführt wird. Ziel ist die Erstellung einer Textdatenbank und ein darauf basierendes Wörterbuchs des Klassischen Maya. Im Rahmen des Projekts werden die Text- und Bildträger systematisch und nach einheitlichen Standards beschrieben, das Ausgangsmaterial auf der Basis von XML maschinenlesbar gemacht und auf diese Weise die Grundlagen für die Kompilation des Wörterbuchs geschaffen. Dieses Unterfangen wird mit Methoden und Technologien aus den digitalen Geisteswissenschaften in Angriff genommen. Wesentliche Voraussetzung ist dabei, dass nicht nur der sprachliche Inhalt der Inschriften und die ikonischen Informationen der Bilddarstellungen, sondern auch Daten über den Inschriften- und Bilddträger (Beschreibungs- oder Metadaten) berücksichtigt und in einer Datenbank angelegt werden. Zu diesem Zweck werden in TextGrid Tools und Workflows entwickelt, welche die I. Dokumentation der Schrift- und Bildträger mit Aufarbeitung des Forschungsstandes, II. die epigraphisch-linguistische Auswertung der Hieroglyphentexte sowie III. Edition der Texte mit Transliteration, Transkription und Übersetzung in einem einzigen System ermöglichen. Die VRE enthält nicht nur Beschreibungen der Textträger oder Informationen die Texte, sondern der Datenbanknutzer bekommt mit Hilfe der Literaturdatenbank auch einen Überblick darüber, welche Autoren sich mit einem Monument befasst oder es publiziert haben, eine Textpassage diskutiert oder erstmals eine bis heute gültige sprachliche Lesung einer Hieroglyphe präsentiert haben. Der Textträger erhält dadurch eine ‚Biographie‘, die eng mit dem Textinhalten verwoben ist und bei der Bedeutungsanalyse von Wörtern berücksichtigt wird.

The formation of stars and their accompanying planets occurs in a dynamic environment in which larger scales couple to smaller scales all the way from the infall of gas from the cosmic web into galaxies down to the accumulation of dust to form planetesimals within protostellar disks. To understand the origins of our own Solar System and the observed populations of stars and planets requires simulations that capture the interactions between these scales while modeling the dominant physical and chemical processes at each scale. (Whether these set the stage for biological processes elsewhere is, of course, one of the great unanswered scientific questions.) In this talk I will review my group’s work on such simulations, using multiple numerical techniques.

ECTS: not yet determined

Many problems in machine learning that involve discrete structures or subset selection may be phrased in the language of submodular set functions. The property of submodularity, also referred to as a _discrete analog of convexity_, expresses the notion of diminishing marginal returns, and captures combinatorial versions of rank and dependence. Submodular functions occur in a variety of areas including graph theory, information theory, combinatorial optimization, stochastic processes and game theory. In machine learning, they emerge in different forms as the potential functions of graphical models, as the utility functions in active learning and sensing, in models of diversity, in structured sparse estimation or network inference.
The lectures will give an introduction to the theory of submodular functions, their applications in machine learning and related optimization problems.

Part I of the lectures will introduce the concept of submodularity along with several examples, as well as associated polyhedra and relations to convexity. Part II will address the ideas underlying algorithms for minimizing and maximizing submodular functions. For example, those algorithms exploit ties to both convexity and concavity.

ECTS: 2

Discussion of topical challenges to modeling, discretization and adaptive methods and their efficient numerical solution in the context of fluid-structure interaction

After several decades of intensive research, numerical analysis and simulation of fluid-structure interactions remain a challenging topic with a large number of unresolved problems and issues. While the numerical analysis of the coupled system of equations in terms of well-posedness and convergence is typically limited to simple model problems, a lot of insight have been gained over the years by means of numerical simulations. Established methods like the Arbitrary Lagrangian-Eulerian (ALE) method or the Immersed Boundary Method have been succesfully applied to a wide range of applications, including for example aero-elasticity and aero-acoustics, biomechanics, energy or mechanical engineering.

Nevertheless, there are yet a number of problems, where most of the established methods fail or come to a limit. Problems are caused for example by large structural deformations or contact problems, stiff couplings, extreme parameters or a huge computational complexity. In the last years, a number of novel methods and approaches have been developed to tackle such problems many of them being still subject of ongoing research.

An area of research on its own is the development of efficient solvers for the underlying linear systems of equations. The high complexity of real world applications calls for algorithms that include adaptivity in time and space, model reduction, as well as parallelization. In the case of strong couplings, the coupled system of equations is extremely bad conditioned, such that the design of efficient solvers, e.g. multigrid solvers, is a challenge.

This workshop addresses the previously mentioned challenges and aims at bringing together experts and junior scientists in the fields of modeling, adaptive discretizations and solvers for fluid-structure interaction. To provide a platform in order to teach and learn state-of-the art formulations for fluid-structure interaction, this workshop consists of a two-day-school and a subsequent three-day-symposium. The latter one will consist of invited and contributed presentations of junior scientists and experts whereas the school lectures will be given by three young scientists and experts in their field covering each of the three topics of our symposium.

Wir haben die Daten - nutzen wir sie!

Nach Public Domain und Open Source ist Open Data ein weiteres Buzzword, das den Zugang zu digitalen Ressourcen thematisiert.

- Public Domain ist die Idee, Programme kostenfrei zu vertreiben. Sie stammt aus der Urzeit der Programmierung. Viele hochwertige Anwendungen sind daraus entstanden.

- Open Source ist der nächste wichtige Meilenstein, denn erst die Freilegung des Quellcodes garantiert, dass Programme transparent werden und viele Entwickler freie Software stetig verbessern können. Mit Linux hat sich das heute erfolgreichste Server-Betriebssystem dieser Idee verschrieben.

- Open Data ist die logische Weiterentwicklung. Vor allem in Verwaltungsorganen, aber auch in öffentlich geförderten Forschungsprojekten oder in Krankenhäusern werden ständig große Datenmengen erzeugt. Diese Daten frei und umfassend zugänglich zu machen, ist die Idee hinter Open Data.

Dieses Konzept ist bestechend: Wenn die Allgemeinheit auf diese mit öffentlichem Geld geförderten Daten vollen Zugriff hat, kann auf vielfältige Weise ein gänzlich neuer Mehrwert entstehen. Aus diesem Ansatz ergeben sich Chancen und Risiken, die wir am Modellierungstag offen diskutieren wollen.

- Grundsätze bei der Publikation von Open Data

- Vorteile und Nachteile von Open Data für Unternehmen

- Qualitätssicherung in Open Data Projekten

- Geschäftsmodelle auf Basis offener Daten

Zu diesen und weiteren Themen erwarten wir interessante Vorträge aus Wissenschaft und Wirtschaft. Auch die öffentliche Verwaltung ist zum Dialog rund um dieses Thema herzlich eingeladen, hängt doch Open Data eng mit Open Government, dem Konzept der offenen Beteiligung der Zivilgesellschaft an der Verwaltung, zusammen.

Sparsity and inverse problems: a tale of splines and innovations

IWR Colloquium

Speaker: Prof. Michael Unser
Location: IWR, Room 432, Im Neuenheimer Feld 368, 69120 Heidelberg

ECTS: not yet determined

We start with a brief historical account of inverse problems in imaging. We highlight the emergence of the concept of sparsity, which opened the door to the resolution of more difficult image reconstruction problems, including compressed sensing. We then show the optimality of splines for solving problems with total-variation (TV) regularization constraints, which concludes the deterministic part of our story.
Next, we introduce a statistical formulation in which signals are modeled as sparse stochastic processes. These latter entities (including splines) are solutions of non-Gaussian stochastic differential equations and are intrinsically sparse in the sense that they admit a concise representation in a matched wavelet basis. The formalism is applied to the discretization of ill-conditioned linear inverse problems where both the statistical and physical measurement models are projected onto a linear reconstruction space. This leads to the specification of a general class of maximum a posteriori (MAP) signal estimators complemented with a practical iterative reconstruction scheme. While the framework is backward compatible with the traditional methods of Tikhonov and TV, it opens the door to a much broader class of potential functions that are inherently sparse, while it also suggests alternative Bayesian recovery procedures. The approach is illustrated with the reconstruction of images in a variety of modalities including deconvolution microscopy, phase-contrast tomography, and refractive-index microscopy.

Abstract:

Sparse stochastic processes are continuous-domain processes that admit a parsimonious representation in some matched wavelet-like basis. Such models are relevant for image compression, compressed sensing, and, more generally, for the derivation of statistical algorithms for solving ill-posed inverse problems.

The course will introduce the participants to the extended family of sparse processes that are specified by a generic (non-Gaussian) innovation model or, equivalently, as solutions of linear stochastic differential equations driven by white Lévy noise. We shall provide a complete functional characterization of these processes and highlight some of their properties. The two leading threads that underlie the exposition are:

1) the statistical property of infinite divisibility, which induces two distinct types of behavior Gaussian vs. sparse at the exclusion of any other;

2) the structural link between linear stochastic processes and splines.

The formalism lends itself to the derivation of the transform-domain statistics of these processes and to the identification of optimal (ICA-like) representations. We also show that these models are applicable to the derivation of statistical algorithms for solving ill-posed inverse problems, including compressed sensing. The proposed formulation leads to a reinterpretation of popular sparsity-promoting processing schemes such as total-variation denoising, LASSO, and wavelet shrinkage as MAP estimators for specific types of sparse processes, but it also suggests alternative Bayesian recovery procedures that minimize the estimation error.

The lecture notes for the course are available on the web at www.sparseprocesses.org.

Das Zusammenwirken von Physiologie, Orthopädie, Robotik, Regelungstechnik und Materialwissenschaft hat in den letzten Jahren einen rasanten Entwicklungsschub im Bereich der Prothetik und Orthetik ausgelöst. Das Seminar ermöglicht einen Blick auf die aktuelle Forschung im technischen und medizinischen Bereich und zeigt die Möglichkeiten der Anwendbarkeit in der heutigen Medizin. Geschichte, Ethik und Theologie erweitern den Reflektionsraum.
Ziel der Prothetik ist es, Patienten als Ersatz von fehlenden Körperteilen eine individuelle multifunktionale prothetische Versorgung zu bieten, die es ihnen ermöglicht, alltägliche Bewegungen natürlich und ungehindert auszuführen. Spezielle Prothesen, z.B. für bestimmte Sportarten, erlauben den Athleten inzwischen ein derartig hohes Leistungsniveau, dass ihnen teilweise ein Vorteil gegenüber Athleten ohne Prothesen unterstellt wird. Orthesen und Exoskelette hingegen ersetzen keine Gliedmaßen, sondern dienen existierenden Körperteilen Stütze oder Bewegungsantrieb. Ihr Einsatzbereich reicht von der lokalen Bewegungsunterstützung einzelner Gelenke bis zum Enhancement der Kräfte gesunder Menschen und zur Ganggenerierung bei Querschnittsgelähmten.
Vor 100 Jahren, im Ersten Weltkrieg, füllten Hunderte von Prothesen-Modellen die Ausstellungssäle populärer Kriegsausstellungen. Aus historischer Sicht werden technische, medizinische und soziale Entwicklungen und ihre Auswirkungen auf Patienten analysiert. In der Philosophie bestimmt die Enhancement-Debatte die Diskussion über Chancen und Risiken der Robotik. Aus ethischer Sicht wäre zu fragen, inwiefern Prothetik und Orthetik auch die Person als Ganzes betreffen und als Eingriff in die Persönlichkeit verstanden werden müssen. Diese Frage stellt sich insbesondere, wenn man Körper und Persönlichkeit nicht dualistisch trennt, sondern das menschliche Leben als prinzipiell verkörpertes versteht, so dass alle körperlichen Prozesse stets in einem Wirkungszusammenhang mit psychischen Prozessen stehen.

Numerical methods for phase-field fracture propagation

Talk

Speaker: Dr. Thomas Wick
Location: URZ, Seminar Room 215, Im Neuenheimer Feld 293, 69120 Heidelberg

ECTS: not yet determined

Currently, fracture propagation is a major topic in applied mathematics and engineering. It seems to turn out that one of the most promising methods is based on a variational setting and more specifically on a thermodynamically consistent phase-field model. Here a smoothed indicator function determines the crack location and is characterized through a model regularization parameter. In addition, modeling assumes that the fracture can never heal, which is imposed through a temporal constraint, leading to a variational inequality system.
The basic fracture model problem is augmented with several hints and discussions of serious challenges in developing numerical methods for fracture propagation. Key aspects are robust and efficient algorithms for imposing the previously mentioned crack irreversibility constraint, an heuristic solution of the otherwise indefinite Jacobian matrix, computational analysis of the interplay of model and discretization parameters, goal-functional evaluations, coupling to other multiphyics problems such as fluid-filled fractures in porous media, and steps towards high performance computing for tackling practical field problems.

Due to ever increasing product complexity of today_s and tomorrow’s products, the role of simulation is changing rapidly. Without simulation we would not be able to handle the ever growing complexity of our products at the speed innovations are emerging today. Additionally simulation is not only a key technology for engineering but simulation per se is expected to be of a fundamental value customers are paying for, e.g. as an assist system for optimal operation of products, systems, and infrastructures.

In this talk, I provide a short overview on Computer Aided Engineering in an industrial context as well as highlighting three innovation topics exploiting state-of-the-art mathematical research: Interactive Computer Aided Engineering, Plug & Play Multi-X-Simulation, and Simulation-based Assist Systems.

ECTS: not yet determined

The geometric shortest path problem: computing approximately the shortest path between two points in a geometric domain such as a simple polygon or on a polytope, is a fundamental problem in computational geometry and is already solved using Steiner points and graph tools on the entire domain.

In this talk I will introduce the method of multiple shooting for solving the problem. It includes the factors: (f1) partition of the domain, (f2) the collinear/straightest condition for the shortest path at shooting points, and (f3) refinement of shooting points. In particular, the method no longer relies on Steiner points and graph tools on the entire domain.

Our corresponding algorithms are implemented in C and comparisons with Lee and Preparata`s algorithm (in a simple polygon) on running time, with Agarwal, Har-Peled, and Karia`s algorithm (on a polytope) on the accuracy of the approximate shortest paths, are presented. This is a joint work with N. N. Hai and T. V. Hoai.

In the field of robotics, the task of actively balancing on a narrow support, such as a point or line, is usually seen as a control problem; and it has been solved many times using various ideas from control theory. This talk takes a fresh look at the problem from a physical point of view, which yields both a simple model of the physical process of balancing and a simple control system to accomplish it. For the special case of balancing in a plane, the robot’s behaviour is characterized by just two numbers, and the controller’s gains are trivial functions of these numbers. The talk will also explain how it is possible to use a single motion freedom to perform two tasks at once: balance the robot and simultaneously follow a commanded motion trajectory. Several examples of balancing behaviours will be shown and explained.

Probabilistic Graphical Models Workshop 2015
[ more ...]

Workshop

Speaker: Various
Location: HCI, Speyerer Str. 6, 2nd floor, room H 2.22
Link:

ECTS: 0

Probabilistic graphical models provide a consistent framework for the statistical modeling and the computational analysis of scientific empirical data. The past decade has witnessed a significant increase in respective research in the field of image analysis and related application areas, driven by the synergy between statistics, pattern recognition, computer vision and machine learning. The objective is to devise models that enable to infer a coherent global interpretation of noisy and ambiguous local image measurements, taking into account spatiotemporal context in images and videos, and domain-specific contextual knowledge.

Applications of probabilistic graphical models to such large-scale problems raise numerous research problems of modeling and algorithm design for inference and learning, requiring interdisciplinary expertise in applied mathematics, computer science and physics, besides a profound knowledge of the respective application areas.

The basic intention of the Research Training Group is to gather experts from these fields and to establish a coherent research and study program on probabilistic graphical models, with a focus on spatial and spatiotemporal models and their applications in image analysis. The project treats methodological basic research on an equal footing with challenging scientific applications of image analysis in environmental science, life sciences and industry.

The Research Training Group will provide a scientifically unique environment for study, collaboration and innovative research on probabilistic graphical models across disciplines, producing highly-qualified candidates for research careers in academia and industry.

The computerized revolution poses challenges and creates new opportunities in prehistorical research of the Southern Levant. The Computerized Archaeology Laboratory at the Hebrew University integrates techniques and ideas from computer science (e.g., computer graphics, machine learning) in the archaeological research methodologies. We operate optical scanners which provide three dimensional (3D) digital models that are analyzed with computer programs developed in our laboratory. We address research issues and needs which could not be addressed without the availability of digital 3D models. Beyond ‘capturing’ and visualizing data, I will focus on the process of analysis and provide novel ways of interpretation. Several examples will be presented as the clustering between prehistoric lithic assemblages while verifying or negating the traditional classification. This will provide new insights to the path of Homo Erectus out of Africa c.a. 1.4 million years ago and the Neanderthal occupation in the Southern Levant c.a. 100,000 years ago.

Compact course on data assimilation
[ more ...]

Compact Courses

Speaker: Prof. Peter Jan van Leeuwen
Location: IWR, Room 532, Im Neuenheimer Feld 368, 69120 Heidelberg

ECTS: 3

Data assimilation is the science of combining observations of a system with a numerical model of that system. It is used to initialise a model for prediction, like in numerical weather prediction, to provide a good estimate for the long evolution of a system, for instance in weather and climate reanalysis, and for model improvement via parameter estimation and sometimes even parameterisation estimation. It is used in all geosciences, but also in traffic control, neurosciences, agriculture, the process industry etc etc.

This course will provide a compact overview of the data-assimilation methods used, with emphasis on the geosciences. We will discuss traditional methods like 3DVar and 4DVar, Kalman Filters and their ensemble variants, but also new developments like hybrid methods, and fully nonlinear methods like particle filters. The lectures are accompanied by computer practicals in which the participants will get hands-on experience with the functioning of all these methods, and their pro’s and con’s. Use will be made of the EMPIRE data-assimilation system, which contains a whole suite of ensemble-based data-assimilation methods, and a whole suite of models used in the geosciences such as atmosphere models, ocean models, land-surface models, space weather models etc. Unique is the fast and efficient connection of any complex model with the EMPIRE data-assimilation system via MPI statements.

The outcome of the course will be a thorough understanding of the basics of present-day and potential future data-assimilation methods, their pro’s and con’s, and some experience with using them on systems of up to intermediate complexity.

Computing Art. A summer school for digital art history
[ more ...]

School

Speaker: Various
Location: Heidelberg Academy of Sciences and Humanities & HCI
Link:

ECTS: 2

Digital art history is considered to be part of the discipline of art history as well as part of digital humanities as digitally based methods require an interdisciplinary approach. In short, this means using digital infrastructures and tools, but also critically reflecting upon their usage and understanding the technical background (quoted from “Memorandum zur digitalen Kunstgeschichte in der Lehre” (memorandum on digital art history in education)). Digital art history is not only faced with the challenge of analysing objects as primarily art historical research subjects not only in the context of increasingly mimetic digital representations, but also of embedding these representations in the semantic and stylistic contexts of the artwork. In order to succeed in these challenges, immediate access to the visual information of the digital representation, as well as access to virtual research environments which will help to depict semantic relations, is required.

Starting with the digital representation of the artwork, the summer school for digital art history demonstrates ways of processing the artwork visually, iconographically and contextually. The focus is on new methods of annotation and image analysis. Up until now nearly all steps of digital image exploitation were left up to various experts: content processing was the task of student assistants and often highly qualified art historians whereas the creation of new digital records only concerned IT specialists or ambitious self-educated scholars. New exploitation strategies, such as crowd sourcing, machine learning and computer vision, provide the specialist with algorithms/artificial intelligence and laypersons that enable effective mass processing of image data. In addition, new collaborations and interdisciplinary links are forming between the classical scientific fields. The digital image is not only described, but also analysed in terms of content and compared with others. These processes must be developed and critically monitored.

Embedded Boundary Methods for flow in complex geometries
[ more ...]

Talk

Speaker: Sandra May, PhD
Location: SR 215, INF 293 (URZ)

ECTS: not yet determined

Cut cells methods have been developed in recent years for
computing flow around bodies with complicated geometries. They are an
alternative to body fitted or unstructured grids, which may be harder to
generate and more complex in the bulk of the flowfield. Cut cell methods
\"cut\" the flow body out of a regular Cartesian grid. Most of the grid is
regular. Special methods must be developed for the \"cut cells\", which are
cells that intersect the boundary. Cut cells can have irregular shape and
may be very small. We present a mixed explicit implicit time stepping
scheme for solving the advection equation on a cut cell mesh. The scheme
represents a new approach for overcoming the small cell problem: namely,
that explicit time stepping schemes are not stable on the arbitrarily
small cut cells. Instead, we use an implicit scheme near the embedded
boundary, and couple it to a standard explicit scheme used over most of
the mesh. We compare several ways of coupling the explicit and implicit
scheme, and prove a stability (TVD) result for one of them, which we call
“flux bounding”. We present numerical results in one, two, and three
dimensions. These results show second-order accuracy in the $L^1$ norm and
between first- and second-order accuracy in the $L^{\\infty}$ norm. (Joint
work with Marsha Berger.)

Data Vortex General Purpose Fine-Grained Parallel Computers: Designed by a Mathematician for the Scientific Community to Solve the Hardest Problems
[ more ...]

Talk

Speaker: Dr. Coke S. Reed
Location: INF 368, room 248

ECTS: 0

Excerpt from Abstract:

"The Data Vortex network enables scientists to perform work on problems that rely on a tremendous flood of processor-to-processor communication, something that present-day computers handle quite poorly. For example, the Data Vortex is used to perform the FFT algorithm. In 1805, Karl Friedrich Gauss used the Fast Fourier Transform to determine the trajectories of the comets Pallas and Juno. It is of note that the original manuscript of Fourier on the subject of Fourier analyses appeared in 1807. The Gauss work describes the data flow of the transform. It is of interest that the Data Vortex computer enables this FFT data flow on a general purpose computer for the first time. This topic of FFT data flow as well as the general topic of data flow algorithms on Data Vortex computers will also be discussed.

Dr. Reed’s talk will be followed by a brief overview of the Data Vortex family of high performance computers currently being manufactured by Plexus, Inc. This overview, given by Mr. Bill Stube, Data Vortex Project Manager for Plexus, Inc., will include a high-level description of the Data Vortex enabled system characteristics, performance comparisons to present-day leading supercomputer systems, and an overview of the simple programming model used by Data Vortex researchers to port their work onto Data Vortex computers."

Computational Methods in Uncertainty Quantification

Compact Courses

Speaker: Prof. Robert Scheichl
Location: IWR, Im Neuenheimer Feld 368, 69120 Heidelberg, various rooms
Link:

ECTS: 3

Compact Course Schedule:

June 11, 9:00-10:30 Room 520
June 12, 9:00-10:30 & 14:00-16:00 Room 532
June 15, 9:00-10:30 & 11:00-12:00 Room 532

June 17, 9:00-10:30 & 14:00-16:00 Room 432

The term “Uncertainty Quantification” is as old as the disciplines of probability and statistics, but as a field of study it is newly emerging. It combines probability and statistics, with mathematical and numerical analysis, large-scale scientific computing, experimental data, model development and application sciences to provide a computational framework for quantifying input and response uncertainties which ultimately can be used for more meaningful predictions with quantified
and reduced uncertainty.

We will motivate the central questions in computational uncertainty quantification through some illustrative examples from subsurface flow,
weather and climate prediction, material science, nuclear reactor physics and biology. The key challenge that we face in all those
applications is the need for fast (tractable) computational tools for high-dimensional quadrature. After a short overview of the available techniques, we study sampling-based approaches in more detail. We put a particular emphasis on multilevel (or multiscale) methods that exploit the natural model hierarchies in numerical methods for partial differential equations. In the final part of the course, we will briefly consider the inverse problems of Bayesian inference, data assimilation and filtering and show how the multilevel techniques presented in the earlier parts of the course can be extended to these more challenging tasks.

A rough outline of the course is:

- Introduction: What is Uncertainty Quantification?
- Motivating Examples from the Earth Sciences, Material Sciences,

Physics and Biology
- High-dimensional quadrature and tractability
- Uncertainty Propagation: “The Forward Problem” Sampling-based approaches
- Basic Monte Carlo Simulation
- Quasi-Monte Carlo Methods
- Multilevel Monte Carlo Methods
- Stochastic Collocation and Polynomial Chaos
Uncertainty Quantification: “The Inverse Problem\"
- Bayes’ Rule and Bayesian Inference
- Markov Chain Monte Carlo
- Multilevel Bayesian Inference
- Future perspectives: Data Assimilation and Filtering

Target group

Doctoral students, postdocs and master students with an interest in reliable scientific computing.

Aims of the course

The aim of the course is to give a basic, hands-on introduction to the evolving field of large scale uncertainty quantification, with a particular emphasis on novel sampling based approaches for high dimensional parameter spaces. Using the tools and techniques addressed in the course, students should be able to decide independently which computational approaches are most suited to a given problem and carry out simple uncertainty quantification studies in their field of study. They should also be able to give a basic assessment of the complexity of the various approaches and assess their feasibility in a given situation.

The field of computational origami is focused on the development of algorithms for origami design: construct a fold pattern that meets specific objects for the 2D unfolded form, the 3D folded form, and in some case, the phasespace path for transitioning between the two. In this talk I will present several recent developments in origami design algorithms and will show examples of their construction, some rendered in pixels, some rendered in paper.

Robert J. Lang is recognized as one of the foremost origami artists in the world as well as a pioneer in computational origami and the development of formal design algorithms for folding. With a Ph.D. in Applied Physics from Caltech, he has, during the course of work at NASA/Jet Propulsion Laboratory, Spectra Diode Laboratories, and JDS Uniphase, authored or coauthored over 100 papers and 50 patents in lasers and optoelectronics as well as authoring, coauthoring, or editing 14 books and a CDROM on origami. He is a fulltime artist and consultant on origami and its applications to engineering problems but keeps his toes in the world of lasers, most recently as the EditorinChief of the IEEE Journal of Quantum Electronics from 2007-2010. He received Caltech’s highest honor, the Distinguished Alumni Award, in 2009 and was elected a Fellow of the American Mathematical Society in 2013.

HGS MathComp Public Lecture

The last decade of this past century has been witness to a revolution in the development and application of mathematical techniques to origami, the centuries-old Japanese art of paper-folding. The techniques used in mathematical origami design range from the abstruse to the highly approachable. In this talk, I will describe how geometric concepts led to the solution of a broad class of origami folding problems – specifically, the problem of efficiently folding a shape with an arbitrary number and arrangement of flaps, and along the way, enabled origami designs of mind-blowing complexity and realism, some of which you’ll see, too. As often happens in mathematics, theory originally developed for its own sake has led to some surprising practical applications. The algorithms and theorems of origami design have shed light on long-standing mathematical questions and have solved practical engineering problems. I will discuss examples of how origami has enabled safer airbags, Brobdingnagian space telescopes, and more.

Good Scientific Practice
[ more ...]

Workshop

Speaker: Dr. Sita Schanne
Location: IWR, Room 520

ECTS: 1

Serious cases of scientific misconduct have been reported in the media recently. But beside the most prominent cases several shades of questionable scientific practice might undermine the integrity of the sciences. Based on the recommendations for “Safe Guarding Good Scientific Practice” by the Deutsche Forschungsgemeinschaft this course wants to support doctoral students to develop a responsible professional conduct as a researcher.
In this one-day workshop you will gain a general understanding of good scientific practice and scientific misconduct (e.g. plagiarism, fabrication, falsification). We will explore key areas of conflict, critical situations and possible causes of misconduct. Questions regarding data management, documentation and ownership will be addressed, as well as the correct use of references and problem areas in the publication process. Furthermore we will reflect on aspects of a functioning supervisor- student- relationship as a factor to prevent scientific misconduct.

Trust-region adaptive stochastic collocation for PDE optimization under uncertainty
[ more ...]

Talk

Speaker: Prof. Matthias Heinkenschloss
Location: IWR, INF 368, Room 432

ECTS: not yet determined

I will present a trust-region algorithm with adaptive sparse grids for the solution of optimization problems governed by partial differential equations (PDEs) with uncertain coefficients. The algorithm adaptively builds two separate sparse grids: one to generate optimization models for the optimization step computation, and one to approximate the objective function to evaluate whether to accept the step. The quality of the adaptive sparse grid models is determined by the trust-region algorithm. Conditions on inexact function and gradient evaluations in previous trust-region frameworks are extended to allow the rigorous use of asymptotic (discretization) error estimates for objective function and gradient approximations.

The algorithm often generates adaptive sparse grids that contain significantly fewer points than the high-fidelity grids, which leads to a dramatic reduction in the computational cost. Moreover, the numerical results indicate that the new algorithm rapidly identifies the stochastic variables that are relevant to obtaining an accurate optimal solution. When the number of such variables is independent of the dimension of the stochastic space, the algorithm exhibits near dimension-independent behavior.

ECTS: 2

Target Group:
Doctoral students, master_s students, and postdoctoral associates in the mathematical, physical, and engineering sciences

Aims of the course:
The course will introduce students to the theory of total positivity, with concentration on totally positive kernels. The course will emphasize the connections between totally positive kernels and the areas of mathematical statistics, probability inequalities, linear algebra, analysis on the group of unitary matrices, and finite reflection groups. The prerequisites for the course are a strong undergraduate degree in the mathematical or physical sciences.

Course content:
The course will introduce the theory of total positivity with motivating material based on the classic monographs by F. R. Gantmacher and M. G. Krein (\"Oscillation Matrices and Kernels and Small Vibrations of Mechanical Systems\", 2002, revised edition) and S. Karlin (\"Total Positivity,\" 1968).
The second part of the course will cover properties of totally positive kernels and provide applications to probability inequalities arising in mathematical statistics. We will apply methods from linear algebra (such as the Binet-Cauchy principle) and multivariable calculus to ascertain the totally positive properties of specified kernels.
In the third and last part of the course, the lectures will study generalizations of totally positive kernels. The material treated in this section of the course will reveal that there are close connections between the theory of total positivity and harmonic analysis on the group of unitary matrices.

Im letzten Jahr haben wir Sicherheit erhalten, dass mehrere staatliche Institutionen verschiedener Länder den kompletten Internetverkehr überwachen und analysieren. Es drängt sich die Frage auf, wie man seine Daten vor unerlaubtem Zugriff schützen und seine Privatsphäre bewahren kann. Deswegen veranstalten wir sogenannte Cryptopartys, auf denen wir technische Hilfsmittel erklären, mit denen man seine Kommunikation verschlüsseln kann – ohne, dass man ein Computerexperte sein muss.

Die Veranstaltungen sind kostenlos und stehen jedem offen, um Anmeldung wird gebeten (siehe unten).

Was ist eine Cryptoparty?
Auf einer Cryptoparty zeigen wir, dass man kein Computerfreak sein muss, um seine E-Mails zu verschlüsseln. Wir zeigen, wie man etablierte Verchlüsselungs- oder Anonymisierungssoftware installiert und benutzt. Ist diese Software einmal eingerichtet, fällt sie im Alltag kaum noch auf, aber kann Kommunikation effektiv schützen. Teilnehmer können gerne einen eigenen Laptop mitbringen, dann unterstützen wir bei der Installation und Einrichtung.

Anmeldung
Damit wir vorbereiten und planen können, bitten wir um eine kurze und formlose Anmeldung an crypto@noname-ev.de mit der Anzahl der Personen, welcher Termin und, wenn Laptops mitgebracht werden, des verwendeten Betriebssystems. Danke!

Wer seid ihr?
Der NoName ist ein Heidelberger Treff zu computer- und techniknahen Themen aus dem erweiteren Umfeld des Chaos Computer Club. Wir treffen uns jeweils am ersten Donnerstagabend im Monat zu einem Stammtisch in wechselnden Lokalen und an allen anderen Donnerstagen in einem Raum an der Universität.

Fireside Chat "Informatik als Geisteswissenschaft; Geisteswissenschaft als Informatik"
[ more ...]

Talk

Speaker: Prof. Manfred Thaller
Location: IWR, INF 368, Raum 514

ECTS: 0

Bei der letzten Jahrestagung der deutschen Fachvereinigung für die Digital Humanities bot die Eröffnungskeynote unter dem Titel „Informatik als Geisteswissenschaft“ eine Interpretation des Verhältnisses der Disziplinen an, die auf Grund methodischer Eigenschaften der Disziplinen aufzeigte, dass die Informatik den Naturwissenschaften – als Objektwissenschaften – nicht wirklich zuzurechnen sei. Während es einen klaren methodischen Unterschied zwischen den Natur- und den Geisteswissenschaften gäbe, gäbe es keinen wirklichen Grund, warum kein Nahverhältnis zwischen der Informatik und den Geisteswissenschaften möglich sein solle.

In der Tat scheinen mir epistemologisch die beiden Disziplinen weniger fremd, als man meinen sollte. Dazu die folgenden Thesen:

(1) Seit ca. 1960 gibt es einen Problembereich, in dem Vertreter beider Disziplinen versuchen, die methodischen Möglichkeiten der Anwendung der Techniken der Informatik auszuloten. Die Fortschritte sind langsam aber stetig.

(2) Diese Entwicklung wird von heftigen Ausschlägen einer Wellenbewegung überlagert, die von Konjunkturen und Krisen der Anwendung informationstechnischer Werkzeuge auf geisteswissenschaftlich relevante Materialgruppen geprägt ist. Die jüngste dieser Konjunkturen heißt „Digital Humanities“.

(3) Unabhängig von derartigen Konjunkturen gibt es Problemklassen, bei denen die Anwendung bekannter Techniken auf geisteswissenschaftliche Materialien die Grundlagen geisteswissenschaftlicher Arbeit handwerklich so gründlich umgestalten kann, dass sich für die Geisteswissenschaften methodische Konsequenzen ergeben, gleichzeitig aber Defizite der angewandten Techniken erkennbar werden.

(4) Diese Defizite rühren daher, dass die „Information“ auf denen die Geisteswissenschaften ihre Analysen gründen, eine Reihe von Eigenschaften hat – genuine Inkonsistenz und Unschärfe – die nur durch eine Verallgemeinerung von Annahmen der Informatik über die Grundlagen der Repräsentation von Information gelöst werden können.

An Introduction to Scalar Field Topology
[ more ...]

Talk

Speaker: Dr. Julien Tierny
Location: IWR, Room 432, Im Neuenheimer Feld 368, 69120 Heidelberg

ECTS: not yet determined

Scalar fields are a versatile and integral part of many applications: In computer graphics, they appear in the form of the classical heat kernel shape descriptors. In molecular chemistry simulations, scalar fields derived from electron density are used to model complex molecular interactions.

Scalar fields are very appealing for analysing and visualizing complex data sets because they permit a precise mathematical theory that is largely based on Morse theory.

In this talk, Julien Tierny of the French National Centre for Scientific Research will give an introduction to this topic and outline past and current research. The talk is specifically geared towards an audience of non-experts in topological methods.

A discrete variational approach to hybrid dynamical systems and optimal control
[ more ...]

Talk

Speaker: Prof. Sigrid Leyendecker
Location: Speyerer Str. 6, Raum 2.22, 69115 Heidelberg
Link:

ECTS: 0

The optimal control of human walking movements requires simulation techniques, which handle the contact_s establishing and releasing between the foot and the ground. The system_s dynamics switches non-smoothly between phases with and without contact making the system hybrid.

During motion phases without switch, the direct transcription method Discrete Mechanics and Optimal Control (DMOCC) is used to transform the optimal control problem into a constrained optimisation problem. It involves a mechanical integrator based on a discrete constrained version of the Lagrange-d_Alembert principle. This integrator represents exactly the behaviour of the analytical solution concerning the consistency of momentum maps and symplecticity. To guarantee the structure preservation and the geometrical correctness during the establishing and releasing of contacts, the non-smooth problem is solved including the computation of the contact or contact release configuration as well as the contact time and force, instead of relying on a smooth approximation of the contact problem via a penalty potential.

While in a first approach, the sequence (not the switching time) in which the closing and opening of contacts follow each other is considered as known, a more general approach is the optimisation of the whole locomotion requiring a combined model including transitions between the different dynamical systems. Integer valued functions can be used to control if and when the switch to another dynamical system occurs, i.e. they permit to control the sequence and switching times of the dynamical systems. A variable time transformation allows to eliminate the integer valued functions and therefore to apply gradient based optimisation methods to approximate the mixed integer optimal control problem.

Developments towards 4D+ imaging for turbulent combustion research

Talk

Speaker: Prof. Dr. Volker Sick
Location: IWR, INF 368, R 248

ECTS: not yet determined

Advances in combustion science and technology depend ever more critically on our ability to formulate descriptions that enable predictive simulations for fundamental insights and for the design of technical combustion systems. Experimentally discovering and characterizing new insights into the physics and chemistry of combustion is foundational in that context. Over the past decade, advances in instrumentation have enabled measurements to image mixing, ignition, and flame evolution at relevant real-time scales. New laser sources, digital cameras, and image processing capabilities have lead to a rapid growth in capability and widespread use of high-speed imaging diagnostics in combustion research. Now, the extensions of these capabilities are being pursued to enable experiments that capture the 3D nature of combustion in single-shot measurements.

This presentation describes examples of 2D and 3D high-speed imaging techniques and their application to study spark-ignited direct-injected internal combustion engines to understand the causes of combustion instabilities that are inherent to these engines.

Some methods for approximate dual control based on MPC
[ more ...]

Talk

Speaker: Tor Aksel Heirung
Location: Im Neuenheimer Feld 368, Room 432

ECTS: not yet determined

Maintaining a good model of a controlled plant is an important challenge
in the process industries, model quality being one determining factor
for the performance of a model predictive controller (MPC). Feldbaum was
the first to recognize that an optimal controller for a system with
unknown parameters has two conflicting tasks: directing the output
toward a reference, and exciting the system for learning purposes so
that better control decisions can be made in the future. A dual
controller is optimal in the sense that it finds the best trade-off or
balance between control and excitation.

In this talk we will look at three variations of an MPC based approach
to the problem of controlling a system with unknown model parameters
while simultaneously exciting the system so that the parameter estimates
can be improved and their error variances reduced. Excitation is
explicitly included in the cost functions and balanced against standard
control objectives.

All three algorithms can be implemented with minor modifications to an
existing MPC framework. We look numerical results for each of the three
approaches and compare some advantages and disadvantages. The results
show that parameter identification can be greatly enhanced with only a
small effect on the system output by allowing the controllers to
slightly increase the system excitation in a smart way, and that this
can be achieved without requiring persistent excitation.

The last part of the presentation contains some promising preliminary
experimental results.

ECTS: not yet determined

Simulation software for complex phenomena based on models involving partial differential equations (PDE) has become an important topic in modern research from mathematics and scientific computing providing methods and algorithms to application fields utilizing codes and defining requirements on their technical abilities. Powerful, but also complex mathematical algorithms and advanced hardware architectures have widened the span of practically computable problems considerably. But this power does not come for free and is typically related to complex implementations which have to be developed over many years. The development of powerful, academic, multi-purpose libraries for PDE simulation began about 1990. Nowadays, there are several widespread codes which are well developed and well maintained. These codeas have different characteristics, making them better suited for different problems.

PDESoft conferences provide a discussion venue for developers and users of such libraries as well as researchers who study implementation of computer algorithms for PDE. They serve as a focus point, where the state-of-the-art implementation of state-of-the-art algorithms is discussed. They give developers a chance to share ideas with developers of other packages and users. And users of such sofware have an opportunity to learn about the development principles of software and contribute their knowledge from the point of view of application.

The PDESoft conferences started in 2012 at Universität Münster. After the conference, a considerable number of participants gave positive feedback and it was agreed, that a series of conferences on the topic of PDE-Software was needed. The conference this year is the second in this series.

The 2014 conference will be hosted jointly by the Heidelberg Institute for Theoretical Studies (HITS) and Heidelberg University_s Interdisciplinary Center for Scientific Computing (IWR). The presentations and discussions will take place at the Studio Villa Bosch in Heidelberg, Germany.

The conference is followed by coding days (July 17/18) at the IWR. Two days of joint coding. We will set up infrastructure (power and ethernet) in a single room such that participants can discuss while writing code on their laptops and other devices.

The main object of the event is to mediate a dialogue between the various disciplines. For this purpose, three scientists will give us insights into their research: Prof. Dr. Dagmar Monett Díaz from the Berlin School of Economics and Law, who will talk about the Cuban Blogosphere and its census; Andreas Schieber from the Technical University of Dresden, who will discuss the method of content extraction in weblogs; and Chantal Marquardt from the University of Mannheim, who will elaborate on literary approaches to Francophone North African weblogs.

Key Competences

Speaker: Dr. Philipp Mayer
Location: IWR, Room 520, INF 368, 69120 Heidelberg
Link:

ECTS: 1

/ Description:
Writing grant proposals is a demanding task because evaluation committees expect clear and concise texts. In addition, grant proposals differ in structure and style from other forms of academic writing.

In this workshop, we answer three questions:
- What are characteristics of high-quality grant proposals?
- What are appropriate text structures for proposals?
- Which strategies help to accelerate the preparation of proposals?

Programme:
- Functions of grant proposals: planning, communication, persuasion, contract
- Refining research ideas, choosing and narrowing topics
- Section structure of proposals: problem statement, aims and objectives, literature review, methodology, timetable, budget, etc.
- Differences between proposal writing and paper writing
- Characteristics of high-quality proposals: clarity, correctness, consistency, conciseness, confidence

Activities and time duration:
The workshop includes lectures and exercises. In the exercises, participants analyse sample proposals and draft components of their own proposals.
Half day-workshop: 9 am to 12.30 am or 1.30 pm to 5 pm

Preparation:
- Please think of a research question you want to tackle in your next research project. Describe the problem your research is going to solve (a few sentences are fine). Please bring your notes to the workshop.
- Please ask your supervisor or your colleague for a well-prepared grant proposal. Note the section structure of the proposal and bring this information to the workshop.

HGS MathComp Romberg Inauguration Lecture: Simulating Our Multiscale World - Multilevel Simulation Under Uncertainty
[ more ...]

Public Talk

Speaker: Prof. Robert Scheichl
Location: BZH, INF 328, Room SR25

ECTS: 0

Computer simulation is everywhere in our daily life, be it the designing of novel materials or weather and climate prediction. Simulation is the new heart of science and engineering. It has largely replaced experimentation and prototyping and will play an increasing role in the future. It also has made inroads into new areas of growth, such as the social sciences, medicine and biology.

What all these complicated processes have in common is the vast array of spatial and temporal scales that they span. Brute force computation is impossible even on the biggest supercomputer, and so mathematics plays a central role to reduce the behaviour to simpler, computable models that still retain predictive power on the scales of interest. By looking at various examples, drawn from my research, I will highlight the progress and the challenges for modern scientific computing in simulating our multiscale world, in particular calling attention to the increasingly important field of uncertainty quantification.

Introduction to German Academic Culture
[ more ...]

Workshop

Speaker: Dr. Nils Reschke
Location: IWR, INF 368, 69120 Heidelberg, Raum 520
Link:

ECTS: 1

Every academic culture in general as well as individual disciplinary cultures in particular are characterised by shared basic assumptions and practices that are acquired during the course of study and are handed down and upheld in the practical context at universities and in professional work. It is easy to overlook the fact that basic assumptions and practices of this type are also moulded by cultural differences that not only enrich academic exchange at the international level, but sometimes also impede it. For example, problems can arise at the social level, i.e. with regard to interaction, communication and co-operation, or can be related to the level of academic traditions, i.e. structures of thought and argument.
The goal of the workshop is to make the inherent basic assumptions, rules and expectations of the German academic culture comprehensible to international doctoral candidates and to strengthen their adaptation capabilities. One of the essential objectives of the workshop is to facilitate entry into the foreign culture for the participants in order to reduce stress, misunderstandings and uncertainty and thus to ultimately contribute towards optimal utilisation of personal, time-related and financial resources.

Main focus areas:
- The cultural framework (individual and cultural patterns)
- Underlying structures (comparison of the implicit rules, values and convictions of the German academic system)
- Action-oriented skills 1 (social interaction with colleagues and supervisors)
- Action-oriented skills 2 (academic argumentation)

Multilevel-Verfahren für die Optimierung bei partiellen Differentialgleichungen basierend auf Adaptivität und reduzierten Modellen

Location: Im Neuenheimer Feld 368, IWR, Room 248

ECTS: not yet determined

Wir betrachten Optimierungsprobleme, in denen partielle
Differentialgleichungen als Nebenbedingungen auftreten. In den letzten
Jahren wurden erhebliche Fortschritte bei der Entwicklung von
Multilevel-Optimierungsverfahren gemacht, die adaptive
Diskretisierungstechniken, reduzierte Modelle und a
posteriori-Fehlerschätzer in effizienter Weise verbinden. Diese
Verfahren eröffnen das Potential, Optimierungsiterationen auf Basis
relativ billiger Simulationsmodelle zu berechnen und das
Optimierungsproblemen im Aufwand weniger Simulationen der
zugerundeliegenden partiellen Differentialgleichung zu lösen.
Wir diskutieren einen Multilevel-Ansatz, der eine Hierarchie adaptiver
Diskretisierungen während der Optimierungsiteration auf Basis
adaptiver FE-Diskretisierungen und reduzierter Modelle wie POD
erzeugt. Die adaptive Verfeinerungsstrategie beruht auf a
posteriori-Fehlerschätzern für die zugrundeliegende Zustandsgleichung,
adjungierte Gleichung und das Stationaritätsmaß. Der resultierende
Algorithmus kann bestehende adaptive PDE-Löser und Fehlerschätzer
modular einsetzen. Neben der Behandlung von Steuerungsnebenbedingungen
gehen wir auch auf die Behandlung von Zustandsschranken ein. Wir
demonstrieren die Effizienz des Ansatzes
anhand von numerischen Ergebnissen.

New techniques for solving large sparse linear system of equations in parallel
[ more ...]

Talk

Speaker: Prof. Murat Manguoglu
Location: INF 368, Room 248

ECTS: not yet determined

Parts of this talk is a joint work with Ahmed H. Sameh (Purdue University), Faisal Saied (NYU-AD), Georgios Kollias (IBM Thomas J. Watson Research Center), Ercan Bolukbasi (METU) and Omer Tari
(METU).

Solution of sparse linear systems in parallel computing platforms
requires two main steps which are critical: (1) Reordering the sparse
matrix and (2) direct or iterative algorithms for solving the
reordered system of equations. In this talk we will talk about novel
algorithms that improve the parallel scalability in both steps.

In the first part of this talk, we will present a new multithreaded
and recursive variation of the DS factorization based parallel direct
sparse solver. We show the improvement compared to the sparse LU
factorization based multithreaded Pardiso direct solver on a shared
memory architecture.

In the second part, we will present recent results on obtaining the
Fiedler vector and the permutation induced by the Fiedler vector
effectively on a parallel computing platform. We will show a
significant parallel improvement using our algorithm compared to a
highly effective sequential counterpart in the Harwell Subroutine
Library. We will also apply this permutation to extract a banded
preconditioner and solve the linear systems of equations in parallel
using PSPIKE scheme.
If time permits, we will also present a new reordering scheme based on
the largest eigenvector of the graph Laplacian. From any given sparse
matrix, the new reordering scheme can create a 2x2 block form with
favorable properties.

Talk

Speaker: F. Jug, D. Kainmueller
Location: Dresden

ECTS: 0

Abstract:
This is a slightly unusual talk but we think the audience will enjoy the following three related presentations. The first speaker, Florian Jug, will start by showing some biological data in order to make the point that BioImaging is essential for gaining insights into underlying biological processes. It will be apparent that segmentation, matching, and tracking are of central importance for most questions to be answered. The second part of our talk, held by Dagmar Kainmüller, gives one concrete and detailed example of a recently developed matching procedure we call \"Active Graph Matching\". This method combines the well-established Active Shape Models and graph matching, more precisely with wide baseline matching via dual decomposition. We successfully applied Active Graph Matching for the task of simultaneous segmentation and annotation of nuclei in C. elegans larvae. In the last part of our presentation, Carsten Rother will briefly introduce the Computer Vision Lab Dresden. He will also present some initial results on projects which run in his group, which are mainly about correspondence problems in RGBD images and on detection and pose estimation of chairs and other objects (joint work with Oxford University)

FOMOCOG 14 - Formal Models of (Dis)Ordered Cognition
[ more ...]

Workshop

Speaker: various
Location: Internationales Wissenschaftsforum Heidelberg (IWH), Hauptstraße 242, 69117 Heidelberg
Link:

ECTS: 2

Computational modeling and simulation of human cognition is an emergent multidisciplinary field of research promising breakthroughs for both basic research and applications. There is already a wide range of notable examples illustrating the successful application of computational modeling in cognition from models of working memory to intelligent tutoring systems. However, many psychiatric and neurological disorders involve characteristic cognitive deficits that still are poorly understood on a process level.
Quantitative cognitive process models promise to contribute towards filling the explanatory gap between models of basic neural mechanisms and high-level cognitive abilities. Mathematical methods and computational tools for process modeling, which have a long success story in other disciplines, e.g. chemical engineering, may help to address the challenges and potential pitfalls arising in this approach. A successful implementation, however, requires a broad range of skills and knowledge.
Therefore, in this challenge workshop, we bring together experts from the different fields of cognitive modeling, cognitive disorders, and process modeling. The aim is to facilitate the exchange about research questions in domains like psychiatry, neuroscience, or cognitive science, which may be addressed by methods of process modeling. We will discuss the available methodological approaches and tools as well as their limitations in order to foster effective future collaborations.
The focus of this workshop will be on higher cognition and its disorders, including process models of the underlying neural activity. A methodological focus will be on effective parameter estimation methods, model validation procedures, model-based optimum experimental design, and the application of these methods to models of cognition.

Target Audience
Researchers interested in quantitative models of cognition, particularly higher cognition and models of dysfunctional cognition. Relevant fields include psychiatry, geriatrics, psychology, cognitive science, neuroscience, mathematics, economics, computer science, statistics, and related fields. The workshop is also open to doctoral and graduate students.

Example topics
- Studies on process-related aspects of disordered
cognition
- Cognitive models of planning and problem-solving
in psychiatric disorders
- Tracing cognitive activity in real-time using model-
supported EEG/fMRT
- Process-interpretation of fMRT connectivity
analyses
- Modeling age-related decline in cognitive abilities
- Modeling of cognitive effects of neurotransmitter
dysbalances and psychopharmacological
interventions
- Axiomatic analyses of modeling frameworks
- Tractable mathematical formulations of cognitive
models
- Parameter estimation
- Model discrimination and validation
- Model-based optimum experimental design

A Compressed PCA Subspace Method for Anomaly Detection in High-Dimensional Data
[ more ...]

Talk

Speaker: Eric Kolaczyk

ECTS: not yet determined

Random projection is widely used as a method of dimension reduction. In recent years, its combination with standard techniques of regression and classification has been explored. In this talk we present a method for its use in anomaly detection in high-dimensional settings, in conjunction with principal component analysis (PCA) and corresponding subspace detection methods. We assume a so-called spiked covariance model for the underlying data generation process and a Gaussian random projection. We adopt a hypothesis testing perspective of the anomaly detection problem, with the test statistic defined to be the magnitude of the residuals of a PCA analysis. Under the null hypothesis of no anomaly, we characterize the relative accuracy with which the mean and variance of the test statistic from compressed data approximate those of the corresponding test statistic from uncompressed data. Furthermore, under a suitable alternative hypothesis, we provide expressions that allow for a comparison of statistical power for detection. Finally, whereas these results correspond to the ideal setting in which the data covariance is known, we show that it is possible to obtain the same order of accuracy when the covariance of the compressed measurements is estimated using a sample covariance, as long as the number of measurements is of the same order of magnitude as the reduced dimensionality. We illustrate the practical impact of our results in the context of predicting volume anomalies in Internet traffic data.

Delay Differential Equations in Population Biology and Epidemiology (abstract attached)
[ more ...]

Talk

Speaker: Dr. Maria Vittoria Barbarossa
Location: BioQuant, SR043
Link:

ECTS: 0

In contrast to Ordinary Differential Equations (ODEs), Delay Differential Equations (DDEs) allow for the inclusion of past actions into mathematical models, thus making the model closer to the real-world phenomenon. Most of the results on DDEs have been developed only in the last fifty years (Kuang, 1993), however there is not yet such a comprehensive theory, as for ODEs. In particular, big challenges are given by equations with state-dependent delay. For this kind of problems, indeed, there is nowadays no unified theory, but rather results worked out on the basis of particular classes of equations (Hartung et al., 2006). Applications of DDEs with state-dependent delay is a very modern topic in mathematics and might offer the chance for significant steps forward.
In this talk we will present several applications of delay differential equations with constant and state- dependent delay in the fields of population dynamics and mathematical epidemiology:
• In the context of population dynamics, DDEs with constant delay can be obtained, e.g., from the balance laws of age-structured population dynamics, assuming that birth rates and death rates, as functions of age, are piece-wise constant. The delay arises naturally from biology as the age-at- maturity of individuals. We shall see applications of this modeling approach in population dynamics of isolated populations (Barbarossa et al., 2013), interplay of predators and prey (Mohr et al., 2013), tumor modeling (Barbarossa et al., 2012), as well as for the control of mosquitoes by mean of sterile insect technique.
• In epidemiology a delay can represent for example the duration in time of incubation or time a host stays infected. However, delay equations can be also used to investigate the phenomenon of waning immunity. When the body gets infected by a virus, indeed, the immune system develops a certain resistance against it. As a matter of fact disease-induced immunity tends to wane and, long time after recovery, an individual might become again susceptible to the virus. Exposure to the pathogen boosts the immune system, thus prolonging the time in which the individual is immune (Heffernan et al., 2009). We shall model the feedback mechanism which makes possible for certain individuals to have lifelong immunity, being regularly exposed to the infection.

The Roman poet Ovid (43 BC – AD 17/18) wrote eloquently that in life, \"Medio tutissimus ibis\": \"You will go safest in the middle.\" But where is the middle to be found, and how do we know when we have found it? These questions are difficult to answer if only because the search for the middle requires that we hold in check our basic human impulses.

In this inaugural lecture, I will elucidate the importance of searching for the middle in several contexts. I will provide examples of ways of proceeding cautiously through life, instances from the process of scientific discovery, and illustrations from research in mathematical statistics.

In the case of mathematical statistics, I will demonstrate connections between the search for the middle and many problems in the integral calculus that I have studied for the past 35 years.

HGS MathComp von Neumann Lecture: The Secret of Flight - Direct Fem-Simulation of Turbulent Flow
[ more ...]

Talk

Speaker: Prof. C. Johnson
Location: IWR, INF 368, Room 432
Link:

ECTS: 0

We simulate slightly viscous turbulent low Mach number 3d bluff body flow (including streamlined bodies) by computational solution of the incompressible Navier-Stokes equations with a slip boundary condition modeling observed small skin friction, by using a residual stabilized adaptive finite element method, referred to as Direct Fem-Simulation since no turbulence model beyond automatic residual stabilization is used. We find by duality based a posteriori estimation that mean value quantities such as drag and lift are computable to accuracies comparable to experiments. As a key example, we show that the turbulent flow around a complete airplane is computable and inspecting solutions leads to a new theory of flight essentially different from the accepted theory by Kutta-Zhukovsky-Prandtl developed 100 years ago. We find that turbulent bluff body flow in general can be described as potential flow modified by rotational slip separation as a flow which is resolvable computationally using millions of mesh points, except in a far-field wake of little influence on lift and drag, and also is understandable through a mathematical stability analysis.

Quantitative results in stochastic homogenization
[ more ...]

Public Talk

Speaker: Dr. Stefan Neukamm
Location: Institute of Applied Mathematics, INF 294, room 214

ECTS: 0

I will present quantitative results for the stochastic
homogenization of linear elliptic equations with random coefficients in a discrete setting. Classical qualitative homogenization theory states that on large length scales the random coefficients can be replaced by homogenized coefficients that are deterministic and constant in space.
The homogenized coefficients are characterized by a formula that involves the solution to the so called \"corrector problem\". In contrast to periodic homogenization, in the stochastic setting the corrector problem is a highly degenerate elliptic equation on a probability space.
In this talk I will explain how to obtain various optimal estimates on the corrector, on approximations of the homogenized coefficients and on the homogenization error based on quantification of ergodicity. The talk is based on joint work with A. Gloria (Université Libre de Bruxelles) and F. Otto (MPI Leipzig).

The Fundamental Need for Interactions Between Mathematical Theory, Computer Simulations, and Experiments ? A Case Study from Iterative Learning Control

Viewing the relatively new field of Iterative Learning Control (ILC) from a mathematical perspective can easily guide one to work on what appear to be the most relevant research problems, but they are in fact
useless. One expects simulations to assist in focusing the research directions, but cases are shown where they easily lead one to wrong
conclusions. Then the experimentalist might take over to make things work in hardware, but again he can be guided to wrong conclusions.

This case study shows that the interplay between theory, simulations, and experiments has been fundamental to the development of the ILC
field, each approach helping the others to focus on the real issues and not make wrong conclusions. We note that one of the strengths of IWR is its ability to approach problems from all three directions.

Journalistic Writing for Scientists - Writing for the IWR-Spiegel

Key Competences

Speaker: Anna-Lynn Wegener
Location: IWR, INF 368, room 520
Link:

ECTS: not yet determined

Stories about science, technology, health and environment are some of the most exciting and important for the media and for the public. But it often is a challenge for scientists to convey the wonder of new findings in writing and make complex research accessible to a lay audience. One reason for this difficulty is that journalistic writing is quite different from the paper and report writing that researchers normally engage in. It follows its own principles, style and structure, designed to simultaneously entertain and inform the reader. Luckily, journalistic writing is a skill that can be learned and perfected with practice.
This one-day seminar aims to teach the basics of journalistic writing to scientists. Topics covered include:
• Key principles of communication and science journalism
• Picking your story: what makes science newsworthy
• Capturing the reader’s interest: rendering science exciting and understandable
• Different formats of journalistic writing
o News articles: how to write concise and informative news pieces
o Features: how to structure and present longer articles
• Style guide: style and language of journalistic writing
• Effective interviewing: how to gather your information
• Overview of career paths in science communication and journalism
Format of the seminar: This is a one-day seminar (8 hours including a one-hour lunch break). It will comprise a combination of theory lessons and hands-on exercises. All topics will be illustrated with real-life examples of journalistic writing about different scientific disciplines. Parts of the seminar will take the form of an interactive workshop requiring active participation. No prior knowledge or preparation is necessary. Subsequently to the course the participants will be given the task to write a feature article about a science topic of their choice (preferably from their direct research environment or department) as homework to apply and practice the principles covered. They should send their articles to the trainer via email to receive feedback on their work.

ECTS: 3

The Distributed and Unified Numerics Environment (DUNE) is a software framework for the numerical solution of partial differential equations with grid-based methods. Using generic programming techniques it strives for both: high flexibility (efficiency of the programmer) and high performance (efficiency of the program). DUNE provides, among other things, a large variety of local mesh refinement techniques, a scalable parallel programming model, an ample collection of finite element methods and efficient linear solvers.

DUNE-PDELab is a powerful tool for implementing discretisations of partial-differential equations. It helps to substantially reduce the time to implement discretizations and solvers for (systems of) PDEs based on DUNE. It is not only suitable for rapid prototyping but also for building highly performant simulation software and is used by a variety of projects already.

This one week course will provide an introduction to the most important DUNE modules and especially to DUNE-PDELab. At the end the attendees will have a solid knowledge of the simulation workflow from mesh generation and implementation of finite element and finite volume methods to visualization of the results.

Numerical simulations of Fluid Structure Interaction problems via Immersed Methods: a variational implementation
[ more ...]

Workshop

Speaker: Prof. Luca Heltai
Location: INF 368, Room 432

ECTS: not yet determined

Several methods exist in the literature that allow the numerical treatment of FSI problems via two independent grids, one Eulerian, where the independent variable (x) denotes a fixed point in space, and one Lagrangian, \"immersed\" in the first grid, where the independent variable (s) denotes a material particle in a reference domain. The coupling between the two grids can be achieved in several ways, depending on the underlying discretisation techniques.

The original method was first introduced by Peskin (Immersed Boundary Method - IBM) in the late seventies, to simulate the interaction between blood flow and heart valves. In that method, the coupling is obtain via approximations of Dirac-delta distributions, which allowed a clever interpolation between a finite difference grid and a collection of fibers, used to simulate the immersed body. Another type of Dirac-delta approximation (Reproducing Kernel Particle Method - RKPM) was used instead in the first formulation of the Immersed Finite Element Method (IFEM).

By contrast, a truly variational formulation of immersed methods does not require the use of Dirac-delta distributions, either formally or practically. This was shown in the Finite Element Immersed Boundary Method (FEIBM), where the variational structure of the problem is exploited to avoid Dirac-delta distributions at both the continuous and the discrete level.

In this talk, I will present a generalisation of the FEIBM to the case where an incompressible Newtonian fluid interacts with a general hyperelastic solid. Specifically, we allow (i) the mass density to be different in the solid and the fluid, (ii) the solid to be either viscoelastic of differential type or purely elastic, and (iii) the solid to be and either compressible or incompressible. At the continuous level, our variational formulation combines the natural stability estimates of the fluid and elasticity problems.
In immersed methods, such stability estimates do not transfer to the discrete level automatically due to the non-matching nature of the finite dimensional spaces involved in the discretization. After presenting our general mathematical framework for the solution of FSI problems, I will focus in detail on the construction of natural interpolation operators between the fluid and the solid discrete spaces, which guarantee semi-discrete stability estimates and strong consistency of our spatial discretization.

Convergent Adaptive Finite Element Methods:proof techniques, implementation and numerical results
[ more ...]

Compact Courses

Speaker: Dr. Natasha Sharma
Location: Im Neuenheimer Feld 368, Room 248

ECTS: 2

Mathematically, singularities are points in the domain of computation where the solution seems to `blow up‘ e.g. singularities arising from sharp corners. Numerical solutions are often marred by the presence of such singularities which impact its overall accuracy. To overcome this difficulty, it is natural to increase the number of grid points in certain critical regions so that the computed solution is better resolved. The task then, is to efficiently choose such critical regions and to find a balance between refined regions and unrefined regions which would yield an optimal accuracy.

Another issue faced in practical problems arising in physics and engineering, is that little information is known a priori about the computed solution. This necessitates the derivation of reliable estimates(depending only on the data of the problem) for measuring the overall accuracy of such computed solutions.
Adaptive mesh refinement is a fundamental tool in addressing the above issues and this course introduces the adaptive method for the Galerkin approximation to partial differential equations.

The adaptive method algorithm consists of the steps SOLVE, ESTIMATE, MARK and REFINE and we will discuss each of these steps with a focus on the derivation of an estimator which serves as a reliable estimate for the Galerkin approximation. The convergence of the adaptive cycle will be presented and an emphasis will be placed on discussing the techniques used in proving the convergence of this algorithm for both the continuous and discontinuous Galerkin approximations. Numerical results and examples will also be presented. This lecture series will be based on the theory developed over the past decade.

Mathematical and Computational Modelling of Tissue Engineered Bone in a Hydrostatic Bioreactor
[ more ...]

Talk

Speaker: Katie Leonard
Location: BIOQUANT SR 043.

ECTS: 0

The use of tissue engineered implants could facilitate unions in situations where there is loss of bone or non-union, thereby increasing healing time, reducing the risk of infections and hence reducing morbidity. Currently engineered bone tissue is not of sufficient quality to be used in widespread clinical practice. In order to improve experimental design, and thereby the quality of the tissue-constructs, the underlying biological processes involved need to be better understood.

In conjunction with experimentalists, we consider the effect hydrodynamic pressure has on the development and regulation of bone, in a bioreactor designed specifically for this purpose.

To answer the experimentalists’ specific questions, we have developed a time-dependent mathematical model describing the development of the bone-producing cells and mineralised collagen. Two separate hypothesis of the mineralised extracellular matrix deposition rate are considered.

In order to represent experimental results, it is demonstrated that in incluing a decay rate to account for length of loading above a pressure threshold is needed. The mathematical model is then used to computationally screen for operating parameters in order to determine the optimal experimental strategy.

Speaker: Prof. Andreas Griewank
Location: IWR, INF 368, Room 432

ECTS: 0

The local and superlinear convergence of the generalized Newton_s method on regular semi-smooth problems established by Kummer, Qi and others has generated a lot of interest in the last two decades. However theory and algorithmic realization suffer from two related difficulties. Firstly the domain of convergence is unstable with respect to arbitrarily small perturbations of the right hand side. Secondly, this problem of miniscule domains of contraction cannot be overcome by simple stabilisations like line-searches or trust regions. Thirdly, the differentiation rules for generalized Jacobians are only inclusions so that guaranteed elements of these multifunctions can only be produced in exceptional cases. Finally, the considerable effort needed to set up the computation of generalized Jacobians at points of nondifferentiability is usually wasted, because all
actual iterates generated by a solver or optimizer are points of differentiability with probability one. We will indicate how all four problems can be overcome by algorithmic piecewise linearization.

Asymptotically correct discontinuous Galerkin methods for radiative transfer problems
[ more ...]

Talk

Speaker: Prof. Guido Kanschat
Location: 14:15, IWR room 432

ECTS: 0

While discontinuous Galerkin (DG) methods had been developed and analyzed in the 1970s and 80s
with applications in radiative transfer and neutron transport in mind, it was pointed out later in the
nuclear engineering community, that the upwind DG discretization by Reed and Hill may fail to produce
physically relevant approximations, if the scattering mean free path length is smaller than the mesh size. Mathematical analysis reveals, that in this case, convergence is only achieved in a continuous subspace of the finite element space. Furthermore, if boundary conditions are not chosen isotropically, convergence can only be expected in relatively weak topology. While the latter result is a property of the transport model, asymptotic analysis reveals, that the forcing into a continuous subspace can be avoided. By choosing a weighted upwinding, the conditions on the diffusion limit can be weakened. It has been known for long time, that the so called diffusion limit of radiative transfer is the solution to a diffusion equation; it turns out, that by choosing the stabilization carefully, the DG method can yield either the LDG method or the method by Ern and
Guermond in its diffusion limit. Finally, we will discuss an efficient and robust multigrid method for the resulting discrete problems.

Several principles of locomotion for multibody mechanical systems are discussed. Locomotion is based on the change of the system configuration and is possible in the presence of the resistive medium. Snake-like multilink systems, fish-like and frog-like systems, and also systems containing internal moving masses are considered. Various resistance forces including linear and quadratic forces depending on the velocity as well as dry friction forces, both isotropic and anisotropic, are taken into account. Dynamics and control of locomotion are analyzed. Optimal values of the system parameters as well as optimal controls are found that correspond to the maximal speed of locomotion. Experimental results are presented, and possible applications to robotic systems, especially to mini-robots, are discussed. The talk is based on the results obtained in the Institute for Problems in Mechanics of the Rus-sian Academy of Sciences.

Supervoxel-Based Segmentation and Classification, application to biological and medical image analysis
[ more ...]

Talk

Speaker: Aurelien Lucchi
Location: HCI Speyerer Str. 6. 2. Floor Seminar room

ECTS: 0

Immense amounts of high resolution data are now routinely produced thanks to recent advances in imaging techniques. State-of-the-art Computer Vision algorithms designed to operate on natural 2D images tend to perform poorly when applied to b microscopy image stacks for a number of reasons. The size of a typical image stack renders many segmentation schemes intractable. Most approaches rely on local statistics that easily become confused when confronted with the noise and textures. We have proposed an automated graph partitioning scheme that addresses these issues. It reduces the computational complexity by operating on supervoxels instead of voxels, incorporates global shape features capable of describing the 3D shape of the target objects, and learns to recognize the distinctive appearance of true boundaries. Our approach banks on the SLIC superpixels frameworks which has been demonstrated to be a very fast algorithm to create compact and boundary preserving superpixels.

Evidence synthesis for estimating burden of infectious diseases
[ more ...]

Talk

Speaker: Dr. Anne Presanis
Location: BIOQUANT, room 042
Link:

ECTS: 0

Estimation of key characteristics of infectious disease, such as prevalence, incidence or severity, is challenging, as these quantities are typically not easy to measure directly. However, they may be estimated potentially from a network of information from multiple and varied sources, combining these data using evidence synthesis methods. The available data sources relevant to the disease under study may include, for example, surveillance systems, observational studies, registries and community surveys. Such data may be incomplete and/or biased, therefore only indirectly informing the quantities to be estimated. To synthesise such diverse and challenging data usually implies the formulation of complex probabilistic models, often in a Bayesian framework. In the context of such complexity, critical model assessment, including the detection of conflicting evidence, is essential. We illustrate these concepts through examples such as the estimation of HIV prevalence and modelling influenza severity.

Optimizing Counter-Terror Operations
[ more ...]

Talk

Speaker: Prof. Dr. Gustav Feichtinger
Location: IWR, INF 368, r 432

ECTS: 0

Considering the aftermaths of September 11th, it is needless to say that the impact of terror and counter-terror measures poses many complex challenges to decision makers such as governments, security and military organizations. The purpose of the present contribution is to illustrate how methods of optimal control and dynamic games may be applied to
terror related problems to provide insights into questions of how to effectively fight terror. The state variable of such an intertemporal conflict situation, x, corresponds to the number of terrorists (or,
more generally, the power of this organization). In the resulting two-player differential game both opponents have to select the intensity of attacks and counter-attacks both reducing the strength x. Both
opponents have to take into consideration the trade-off between the utility and the costs of their measures. Two versions of a one-state non-zero sum dynamic game are presented. In the first case the terrorists are interested both in becoming powerful (by increasing x) as well as maximizing their attacks, while the target country intends to eliminate as many terrorists as possible. Focusing
our analysis to open-loop Nash equilibria, we are able to derive a stable limit cycle for the long-run behavior. Note that the government´s efforts follow essentially the periodic strength of the terrorists,
whereas the terrorists behave anti-cyclically.

In another version, the target country tries to minimize the strength of the terrorists as well as the intensity of their attacks, while the terrorists_ political objectives induce excessive counter-attacks as an
indirect way of stirring up sentiments against the target country. Moreover, the systems dynamics includes the (undesirable indirect) effect in increasing the recruitment rate of terrorists due to collateral damages induced by the target country´s counter-terror measures. Confining to the interior solutions, we are able to calculate stationary Nash equilibria. Due to the state-separability of this dynamic game, its open-loop Nash equilibrium qualifies as Markovian (feedback) solution. The state-control separability allows to determine also stationary Stackelberg solutions. The explicit calculations allow a comparative static analysis delivering valuable insights into the design of optimal counter-terror strategies.

Abstract:
The complex behavior of turbulence which involves the mixture of the wide range of length and time
scales is the consequence of a fairly simple set of equations – Navier-Stokes equations. However,
analytical solutions to even the simplest turbulent flows do not exist. A complete description of
turbulent flow can only be obtained by numerically solving Navier-Stokes equations. Instead of
solving the statistical evolution of the flow, or including the parameterization of small-scale
turbulence, direct numerical simulation (DNS) aims to resolve the instantaneous flow field. In the
first part of this lecture, we review some contribution of DNS to the turbulence research.
It is well-known that gas exchange across air-sea interface is dominated by the turbulent boundary
layer in the water side. To understand the turbulent behavior in this boundary layer, except to solve
the Navier-Stokes equations, the statistics-based, conceptual model, e.g. surface-renewal model,
random-eddy model, etc. and the hydrodynamics-based model, e.g. large-eddy model, small-eddy
model etc. have been accepted to describe the transfer processes across air-sea interface. In the
second part of the lecture, we briefly introduce these models and their application.

Public Talk

Speaker: Prof. Dr. Britta Schinzel
Location: Mathematisches Institut HS2
Link:

ECTS: 0

In diesem Vortrag werden Absichten und Ergebnisse unseres zweiteiligen DFG-Projekts „Weltbilder der Informatik“ vorgestellt und im Anschluss notwendige Schlussfolgerungen für Unterricht und Studium der Informatik diskutiert.

Das Projekt ging davon aus, dass Weltbilder nicht nur die Ziele der Informatik, sowie die soziale Situation in Studium und Informatikberufen beeinflussen, sondern auch die Art, Nutzbarkeit und Qualität ihrer Produkte.

Im ersten Teil des o.g. Projekts wurden die Weltbilder der Informatikstudierenden hinsichtlich der sieben Schwerpunkte: Technikbild, Wirklichkeitsauffassung, Relation Realität – informatische Rekonstruktion derselben, Menschenbild, Relation Mensch-Maschine, Relation EntwicklerInnen – NutzerInnen, sowie Berufsbild Informatik untersucht. Herausragende Ergebnisse waren dabei u.a. die mangelnde Diversität im Studium der Informatik, sowohl personell als auch hinsichtlich der Inhalte, Foci und Lehrmethoden und ihre Ursachen, die durchs Studium beeinflusste Verantwortungsfrage und das Geschlechterwissen der Studierenden.

In einer folgenden Analyse wurden die gewonnenen Daten ein zweites mal hinsichtlich der Fragestellungen: Bild der Informatik in der Öffentlichkeit, Eigenbild der Informatik und die Situation der Studierenden ausgewertet. Die Ergebnisse können als empirische Basis für die aktuelle Diskussion in den Berufsverbänden und für eine Aktualisierung der Curricula dienen.

Dataflow Computing for Scientific Applications
[ more ...]

Public Talk

Speaker: Dr. Vitali Averbukh and Dr. Oscar Mencer
Location: IWR, Im Neuenheimer Feld 368, 4th Floor Room 432

ECTS: 0

Since the introduction of computers into routine scientific work in the middle of the last century,
their role in the scientific endeavour has changed dramatically from mere auxiliary tools of
numerical computation into an essential element of scientific discovery. The progress in computer
technology has been leading the tremendous advances in the application of numerical techniques in
science. The available computational power and computer memory resources define the scope of
the scientific problems that can be presently addressed, as well as the achievable accuracy level of
theoretical modeling and thus also the reliability of the scientific prediction. Modern science strives
to address more and more challenging problems on a larger and larger scale using accurate
theoretical models. The present scientific objectives of computational quantum chemistry, for
example, include the study of electronic structure of molecular systems relevant to biological and
energy production processes using not only the density functional theory (DFT) techniques, but
also at the more demanding first-principles, or ab initio level. Achieving such challenging goals in
the coming years will require development of principally new powerful computational
technology. Dataflow computing is a new, very promising approach to scientific computation that
has already been proved extremely efficient for a wide range of applications both in academic
science and in the industry. Based on the more than decade-long scientific and technological
development at Stanford, Bell Labs and Imperial College London, dataflow computing equipment
is being now produced on the industrial scale by Maxeler Technologies (London, Palo Alto) and is
provided to academic users through the Maxeler University Programme. Dataflow computers show
acceleration rates of the order of 20x-40x, within the same space and power constraints, for such
diverse applications as Monte Carlo simulations, numerical solutions of ordinary and partial
differential equations, numerical integration methods, finite difference and finite elements methods,
operations with sparce matrices, and have a strong potential to do still better in future. Moreover,
when deployed on the industrial scale, dataflow computing model has led to orders-of-magnitude
lower power consumption and dramatically lower data centre space requirements. The key reason
for the success of the dataflow model is the “vertical” multidisciplinary approach to scientific
computation whereby instead of optimizing algorithms to standard microprocessors, the dataflow
computer is designed to match the given computational problem. This presentation will discuss the
general principle and the implementation details of dataflow computer operation and give an
overview of the applications of dataflow technology. We shall also present the unique user-friendly
dataflow programming environment that makes the exciting opportunities of the dataflow systems
available to the wide community of researchers interested in scientific computing.

Methods for Differentiation in Optimization
[ more ...]

Seminar

Speaker: Prof. Dr. Dr. h. c. Hans Georg Bock, Andreas Schmidt
Location: OMZ, INF 350, Raum U013

ECTS: 4

Numerical methods for the solution of finite dimensional optimization problems often need the computation of derivatives.
The function to be derived might be complicated, e.g. it can contain the solution of a ordinary or partial differential equation. In the seminar we will get to know methods to compute these derivatives. One efficient technique is automatic differentiation, which will be the main focus.

Direct Methods for Sparse Linear Systems
[ more ...]

Seminar

Speaker: Prof. Dr. Dr. h. c. Hans Georg Bock, Dr. Andreas Potschka
Location: IWR, room 532

ECTS: 4

Sparse linear systems of the form A x = b feature only few entries in each row of A. All other entries are zero. Often, these systems are large, with 10,000 to 100,000 rows and columns. Matrices of this type stem from various applications, e.g., the discretization of partial differential equations. In this seminar, we study algorithms that decompose A into easy to solve factors while ensuring sparsity of those factors. These methods can sometimes constitute a convenient alternative to iterative solution methods (compare current course by Mario Mommer).

In den letzten Jahren haben die vermehrten Sozialkontakte durch neue Medien, insbesondere Smart Phones und soziale Netzwerkplattformen, unser privates Leben verändert, und gleichzeitig werden in den Medien immer mehr die globalen Vernetzungen und Verstrickungen in und zwischen den nationalen Markt- und Arbeitssystemen sichtbar gemacht. Die Datenflut nimmt uns die Sicht und schärft gleichzeitig die Sicht anderer auf uns. Wie können diese Strukturen quantitativ bestimmt und untersucht werden? Welchen Einfluss haben Netzwerkstrukturen auf die unser Verhalten, die Kunst und die Sprache, und welchen Einfluss hat unser Verhalten, die Sprache oder die Kunst auf unsere Netzwerke? In diesem Kompaktkurs werden wir uns zuerst mit sogenannten Netzwerkphänomenen beschäftigen: den ‚Small-World-Effekt‘ und das ‚The rich get richer‘-Phänomen, zusammen mit Netzwerkmodellen, die ihre Herkunft erklären. Dann werden verschiedene Methoden vorgestellt, mit denen Netzwerke quantitativ beschrieben und visualisiert werden können. Im letzten Teil des Kompaktkurses werden die Studierenden Referate über Anwendungen der Netzwerkanalysemethoden auf Fragen im Bereich der ‚Digital Humanities‘, der Kunstgeschichte, der Lebensmittelforschung, und den Sprachwissenschaften vorstellen, und weitere Anwendungsmöglichkeiten werden wir gemeinsam diskutieren.

Practical Image Processing
[ more ...]

Compact Courses

Speaker: PD Dr. Christoph Garbe
Location: HCI, Speyerer Str. 6, SR 2.22 and PC-Pool

ECTS: 3

Objectives& Goals
Today, a plethora of image processing algorithms exists, ranging from very basic and easy to implement to highly sophisticated. At the same time, imaging sensors are becoming increasingly wide spread and are quickly being adopted by new application domains. To the practitioner it is often unclear which processes can be automated by image processing routines and which type of algorithm is best suited to solve the problem at hand. At the same time, image processing algorithms make implicit or explicit assumptions with respect to the data or the models used. Using image processing routines in a software package as a ‘black box” entails the risk to choose wrong parameters or or an algorithms in which some assumptions are violated. This may lead to inaccurate or downright wrong results.

In this short course, basic image processing tasks such as image enhancement / denoising, feature detection, object segmentation and -classification as well as motion estimation will be introduced. The concepts of the different approaches will be detailed. The focus will be on understanding how the algorithms work and which assumptions are made. We will skip over stringent mathematical proofs. This short course will introduce the basic algorithms but also give an overview of current state-of-the-art approaches. The course is aimed at practitioners from all fields, but the main examples will be from the field of biology, fluid mechanics and environmental sciences. The course will consist of lectures in the morning and hands on practicals in the afternoon. Basic programming skills are advantageous.

ECTS: 1

Although the number of contacts and projects between the Republic of China and Germany is growing steadily, communication is not always that easy. Different ways of thinking and attitudes among team members quite often cause insecurity, irritations or misunderstanding because they are not familiar with the foreign culture. For Chinese students and employees in Germany, as well as for Germans in China, intercultural communication can be quite a challenge. This one-day workshop offers an important insight into Chinese culture, its impact on modern China and its way of life, and will also contrast similar situations in the German context.

Atomistic-to-Continuum Modeling and Computing
[ more ...]

Compact Courses

Speaker: Prof. Mitchell Luskin
Location: IWR, INF 368, Room 432 & 532
Link:

ECTS: 2

Many materials problems require the accuracy of atomistic modeling in small regions, such as the neighborhood of a crack tip. However, these localized defects typically interact through long-range elastic fields with a much larger region that cannot be computed atomistically. Materials scientists have proposed many methods to compute solutions to these multiscale problems by coupling atomistic models near a localized defect with continuum models where the deformation is nearly uniform on the atomistic scale. During the past several years, a mathematical structure has been given to the description and formulation of atomistic-to-continuum coupling methods, and corresponding numerical analysis has clarified the relation between the various methods and their sources of error. This lecture will begin by introducing the physical and mathematical background and then presenting the current state of numerical analysis for atomistic-to-continuum coupling methods.

The performance of dry powder inhalates
[ more ...]

Talk

Speaker: Prof. Dr. Nora Anne Urbanetz
Location: IWR, INF 368, Room 248
Link:

ECTS: 0

The use of dry powder inhalers (DPIs) in the therapy of asthma bronchiale and COPD (chronic obstructive pulmonary disease) has become more and more popular in the last decades: One of the reasons for this is the environmental friendliness of DPIs in comparison to conventionally used pressurized metered dose inhalers (MDIs), which deliver a solution or suspension of the drug by using environmentally harmful propellants. The challenge of designing a well performing dry powder inhalate is to cope with cohesivity and poor flowability of the drug particles, which, in order to target the deep parts of the lung, have to exhibit aerodynamic diameters between 0.5 µm and 5 µm.
There are several solutions to the problem of poor flowability, the most prominent approach being the attachment of the drug particles to coarse carrier particles of 50 µm to 200 µm, which flow sufficiently well. However, upon inhalation, the drug particles have to be detached from the carrier again in order to ensure, that the drug particles travel along the narrow airways finally reaching the deep lung. So interparticle interactions between the drug and the carrier are crucial with respect to the performance of the inhalate. Another approach is the decrease of interparticle interactions between drug particles of carrier free formulations by covering the drug particle surface with nanoparticles acting as spacers between the drug particles thereby reducing interparticle interactions.
Recent advances in the field of carrier based as well as carrier free formulations targeting the modification and optimization of interparticle interactions will be the main topic of the presentation.

What is Software Engineering and how can it help me in developing better software? Software has become a solid part of research in many areas like physics, biology or medicine. It is used to simulate real world situations that are often too big or too small to be handled in any other way. Errors in Software can have an impact on research findings and at the end get very expensive to correct. Researchers developing software for their own use would like to spend less time coding and concentrate on their research instead. They want to be able to trust the results the software is delivering.
Software Engineering is a profession and field of study dedicated to designing, implementing, and modifying software so that it is of higher quality, more affordable, maintainable, and faster to build (wikipedia). In this course we will learn about some essential Software Engineering principles and techniques. We will take a look at the different activities in a software development process (e.g. design, implementation, testing). We will get to know the 10 software engineering practices (e.g. Version management, Issue Tracking) every scientific software project should use.
In the practical exercises we will take a look at some freeware tools available to accomplish the benefits we have learned about in the lectures.
In the fourth day of the compact you have the opportunity to try the introduced software engineering practices and tools on the software you are developing and discuss your specific software engineering problems with other course participants.

Practical parameter estimation methods
[ more ...]

Compact Courses

Speaker: Prof. Wolfgang Bangerth
Location: INF 368, R 432 (preliminary)
Link:

ECTS: 6

Mathematical models are used throughout all of the natural sciences, engineering, biology and many other areas including the social sciences to describe, understand, and optimize natural and man-made systems. All such models contain parameters specific to this particular system. For example, to describe population growth, we need to know the growth rate; to model the flight of air planes, we need to know the density and viscosity of air; to simulate the nervous system, we need to know the excitation potential of neurons; or to model financial markets, we need to know the statistics of volatility.

Accurate modeling therefore requires us to determine these parameters from observations or experiments. This is the realm of the mathematical field of parameter estimation. This class will discuss the mathematical basics of parameter estimation as well as many practical aspects of its application to problems in the applied sciences. The target audience is graduate students from the non-mathematical sciences interested in modeling in their area, as well as interested mathematics graduate students. I intend to cover the following basic areas, with details to be determined (and
to be adjusted based on the audience):
* Examples of parameter estimation problems
* Mathematical formulation of parameter estimation problems as optimization problems
* Methods of solving parameter estimation problems
* Inverse problems: Parameter estimation for differential equations
* Regularization
* Assessing the accuracy of parameter estimates
* A different viewpoint: Bayesian inversion

Depending on demand, the class may involve student presentations on how to apply these techniques to their own areas of research.

The role of symmetric and asymmetric division of cancer stem cells in developing drug resistance for various types of tumor growth
[ more ...]

Talk

Speaker: Dr. Cristian Tomasetti
Location: Seminar room of IAM, INF 294

ECTS: not yet determined

Often, resistance to drugs is an obstacle to a successful treatment of cancer. Many
attempts to study drug resistance have been made in the mathematical modeling
literature. Clearly, in order to understand drug resistance, it is imperative to have a
good model of the underlying dynamics of cancer cells. One of the main ingredients
that has been recently introduced into the rapidly growing pool of mathematical
cancer models is stem cells. Surprisingly, this all-so-important subset of cells has
not been fully integrated into existing mathematical models of drug resistance. In
this work we incorporate the various possible ways in which a stem cell may divide into the study of drug resistance. We derive a new estimate of the probability of
developing drug resistance by the time a tumor is detected, and calculate the expected number of resistant cancer stem cells at the time of tumor detection. We are also able to obtain analytical results for cases where the average exponential growth of cancer has been replaced by other, arguably more realistic types of tumor growth. Finally, to demonstrate the significance of this approach, we combine our new mathematical estimates with clinical data to show that leukemic stem cells must tend to renew symmetrically as opposed to their healthy counterparts that predominantly appear to divide asymmetrically. (Part of this work is joint with D. Levy, University of Maryland).

A bilevel optimization approach to obtain optimal cost function for human motions
[ more ...]

Talk

Speaker: Sebastian Albrecht
Location: IWR, INF 368, Room 432

ECTS: 0

In literature various cost functions were proposed to explain observed
characteristics in human motions. The underlying assumption is that human
motions are (approximately) optimal with respect to the dynamics. Since
all of these cost functions seem to explain only a limited range of
motions, the question arises: Which cost function is the best for a
considered task? The application examples discussed in this talk are human
arm motions in two and three dimensions.

We use a bilevel optimization approach to solve the following inverse
problem: Which cost function out of a parametrized family composed from
functions suggested in literature reproduces recorded human motion best?
The lower level problem is an optimal control problem governed by a
nonlinear model of the human arm dynamics. The solution strategy is based
on a reformulation of the bilevel program as a one-level problem. This
problem is solved by an interior point solver and problem modifications to
increase solver performance are introduced; results of numerical tests will be stated.
In addition to the optimization results for experiments of human arm
motions, the transfer of obtained cost functions to robotic systems is
discussed.

Adaptive inexact Newton methods for discretizations of nonlinear diffusion PDEs
[ more ...]

Public Talk

Speaker: Prof. Alexandre Ern
Location: IWR, INF 368, Room 432
Link:

ECTS: 0

We consider nonlinear algebraic systems resulting from numerical
discretizations of nonlinear partial differential equations of
diffusion type. To solve these systems, some iterative nonlinear
solver, and, on each step of this solver, some iterative linear
solver are used. We derive adaptive stopping
criteria for both iterative solvers. Both criteria are based on an a
posteriori error estimate which distinguishes the different error
components, namely the discretization error, the linearization error,
and the algebraic error. We stop the iterations whenever the
corresponding error does no longer affect the overall error
significantly. Our estimates also yield a guaranteed upper bound on
the overall error at each step of the nonlinear and linear solvers.
We prove the efficiency and robustness of the estimates with
respect to the size of the nonlinearity owing, in particular, to the
error measure involving the dual norm of the residual. Our
developments are carried at an abstract level, yielding a general
framework. We show how to apply this framework to the
Crouzeix--Raviart nonconforming finite element discretization, Newton
linearization, and conjugate gradient algebraic solution, and we
illustrate on numerical experiments for the $p$-Laplacian the tight
overall error control and important computational savings achieved in
our approach. Finally, we show how to apply our abstract
framework to a broad class of discretization methods. This is joint work
with M. Vohralik (University Pierre et Marie Curie Paris 6).

We discuss different time discretizations of variational type

Among these methods we compare the known continuous
Galerkin-Petrov and the discontinuous Galerkin method with
time polynomial ansatz functions of order k (cGP(k)- and
dG(k)-method) with respect to accuracy, stability and
computational costs. Moreover, we propose two new extended
methods (cGP-C1(k+1)- and dG-C0(k+1)-method) which have on the
one hand a one higher degree of ansatz functions and accuracy,
the same stability properties and on the other hand the same
computational costs as the original methods.

Public Talk

Location: Mathematical Institute, INF 288, Lecture Hall 1
Link:

ECTS: 0

We consider a special class of multi-scale problems, concerning in particular thin composite reticulated structures (of lattice-type) which are periodic structures with big holes and a very small amount of material concentrated along layers (honeycomb struc- tures) or along bars (reinforced structures). They may have a very complex geometrical pattern. From the mathematical point of view, it means that we have to treat partial differential equations depending on several small parameters. The aim here is to give the asymptotic behavior of the solutions with respect to these parameters (which can be the period of the heterogeneities, the thickness of the material, or the thickness of a plate or of a beam in case respectively, of gridworks or cranes).
For the dependence on the period, we use homogenization methods (such as the periodic unfolding in perforated domains) in the directions in which we have periodicity. For the dependence on the small amount of material, a perturbation method is used, enabling us to give explicitly good approximations of real structures. The dependence on the third small parameter is studied by plate and beam techniques. We also give error estimates showing that the final result, when the small parameters are small enough, is close to the original physical one.
It is noteworthy that in all the cases we treat, we end up with simple partial differ- ential equations with constant coefficients that are explicit algebraic expressions of the physical ones.

Probabilistic forecasting of high-impact extreme weather events
[ more ...]

Workshop

Speaker: Prof. Dr. Tilmann Gneiting, Dr. Thordis L. Thorarinsdottir
Location: Internationales Wissenschaftsforum Heidelberg, Hauptstrasse 242

ECTS: 0

Accurate forecasts of severe weather events are of crucial societal relevance and require the joint effort of atmospheric and mathematical scientists. High-impact extreme weather events, such as heavy rainfall and/or strong winds are very often associated with intensive atmospheric fronts with strong gradients or deep moist convection. These events are governed by mesoscale atmospheric dynamics, operating on horizontal scales ranging from a few to several hundred kilometers. The understanding of these dynamics and their inclusion in modern numerical weather prediction models is under constant development while statistical simulation methods are called for to explore the interacting dynamics that happen at subgrid-scales. Similarly, statistical post-processing of the outputs of the numerical weather prediction models is an essential component of precise forecasts which aims to correct for possible biases and the imperfect representation of uncertainty in the forecast. This workshop will bring together academic atmospheric scientists and mathematicians, as well as atmospheric scientists from the German Weather Service to discuss the current challenges in predicting severe weather events and to further strengthen the connections between the two disciplines.

Multi-imager camera arrays for panoramic, multi-viewpoint, and 3D capture

Advances in building high-performance camera arrays have opened the opportunity – and challenge – of using these devices for synchronized 3D and multi-viewpoint capture. In this vein, I will discuss a high-bandwidth multi-imager camera system supporting 72 wide-VGA imagers in simultaneous synchronized 30 and 60 Hz operation uncompressed to a single PC. A 6-imager 1080P60 system is in house, preparing for upgrade from PCI-X to PCIe, where multiple dozens are expected to be supported in sustained video delivery. Such a source of massive synchronized video capture presents new opportunities in imaging, including geometry recovery, immersive experiences, entertainment, surveillance, autonomous navigation, and others. A requirement of using camera arrays for quantitative work is that their relative poses be known, so calibration of these sensing elements is a prerequisite of their use. I argue for use of structured arrays – where imagers_ intrinsics and relative positions do not change, and it is feasible to perform this calibration once, before any use. I will present progress in developing a variety of calibration approaches that capitalize on high quality homographies (non metric) and related camera placement constraints in developing globally optimal solutions, including rectifying homographies, fundamental matrices, epipoles, and epipolar rectification parameters for the entire system. The methods build on what we identify as the Rank-One-Perturbation-of-Identity (ROPI) structure of homologies in posing a unified SVD estimator for the parameters. I will summarize the theory, and present both qualitative depictions and quantitative assessments of our results.

Our use of these camera systems include composing panoramic mosaics for videoconferencing and sports capture, linear baseline multiview capture for automultiscopic display, and geometry recovery using Epipolar Plane structurings. I hope to bring a multi-view camera system with me and demonstrate its capabilities on a laptop.

Much of this work has been done in collaboration with Zeyu Li, studying at UC Berkeley under Ruzena Bajcsy.

Compact Courses

Speaker: Prof. Dr. Anna Marciniak-Czochra and Dr. Mihaela Zigman (Center of Organismal Studies, University of Heidelberg)
Location: INF 294, SR 214

ECTS: 6

To celebrate the centenary of Allan Turing´s birth and the 60th anniversary of his famous paper ,,The Chemical Basis of Morphogenesis__, which settled foundations of mathematical theory of biological and chemical pattern formation, we organize an interdisciplinary seminar aimed to bring together graduate and undergraduate students from mathematics and natural sciences interested in mathematical models and methods as well as biological theories of pattern formation.

The topics of the seminar will include a classical reaction-diffusion theory, as proposed by Turing in his seminal paper and then applied eg. in the activator-inhibitor models, and more recent approaches such as models based on the existence of multiple steady states and switches in the intracellular dynamics and models involving biomechanical interactions within the tissue. Models and related theoretical concepts will be presented and discussed on examples of symmetry breaking and pattern formation in the model organisms of developmental biology (eg. Hydra and Drosophila) as well as in plants.

Nichtlineare optimale Kontrollprobleme: Einführung
[ more ...]

Lecture

Speaker: Dr. Thomas Lorenz
Location: INF 294, AM HS 134
Link:

ECTS: 4

Großgebiet: Nichtlineare Analysis
Inhalt: Gewöhnliche Differenzialgleichungen stellen eine weit verbreitete Grundlage zur Systembeschreibung dar — sowohl in den Naturwissenschaften, der Ökonomie als auch dem Ingenieurwesen. Dabei bieten häufig Parameter eine direkte Möglichkeit, auf das System Einfluss zu nehmen und es zu „steuern“. Das einfache Beispiel eines Schalters macht bereits deutlich, dass diese Parameter im Allgemeinen nicht als stetig (in der Zeit) angenommen werden können.

Diese Vorlesung bietet einen Einstieg in gewöhnliche Differenzialgleichungen, die zusätzlich von einem Parameter abhängen, der (nur) integrierbar von der Zeit abhängt und dessen Werte in einer vorgegebenen Kontrollmenge liegen müssen.
Unter den Lösungen eines solchen sog. Kontrollsystems sind insbesondere jene von Interesse, die ein vorgegebenes Funktional maximieren (bzw. minimieren). Auf der Suche nach den „optimalen Kontrollen“ werden notwendige Bedingungen vorgestellt, die sich mit Hilfe der Hamiltonfunktion oder des Pontryagin_schen Maximumprinzips formulieren lassen.
Literatur: wird bekanntgegeben
Voraussetzungen: Grundvorlesungen Analysis und Lineare Algebra
Zielgruppe: Studierende im Hauptstudium Mathematik (inkl. Lehramt)
Bemerkungen: Die Kontrolltheorie dient in dieser Vorlesung als ein Beispiel für den Schritt von bekannten Resultaten aus dem Grundstudium (insbesondere dem Satz von Picard-Lindelöf über gewöhnliche Differenzialgleichungen) zu entsprechenden Ergebnissen unter deutlichen schwächeren Annahmen.
Dabei soll der Blick für relevante Aspekte in der analytischen Vorgehensweise geschärft werden.

Speaker: Christoph Zimmer, Andreas Sommer, Prof. Dr. Ursula Kummer
Location: Bioquant Building, INF 267, room 042

ECTS: 1

Target audience:
Students with interest in stochastic modeling approaches. No previous knowledge necessary.

Abstract:
Biological systems are often modeled as systems of ordinary differential equations. This approach focuses on the time dependent development of the concentrations of the species in the model. Under certain circumstances, for example small number of molecules or intrinsic stochastic fluctuations, it is necessary to consider these in the modeling approach, as the introduction of stochasticity can alter both qualitative and quantitative behavior of the model. This course will show examples in which modeling with ordinary differential equations is not appropriate, and introduce stochastic differential equations and Markov jump processes as means to cope with stochasticity.
The day starts with a lecture on modeling with ordinary differential equations to have a common starting point, followed by a basic introduction to stochastic differential equations (Ito; calculus) and simple simulation methods are introduced. In the second part of the morning session, the modeling with Markov processes is physically motivated and, for simulation, the standard algorithm of Gillespie is shown.
Although simulation algorithms exists for a long time, parameter estimation in stochastic settings is still a field of ongoing research. Some new results will be discussed here. The day will be completed with a practical lesson on how to perform stochastic simulations with Copasi and Matlab.

The Distributed and Unified Numerics Environment (DUNE) is a software framework for the numerical solution of partial differential equations with grid-based methods. Using generic programming techniques it strives for both high flexibility (efficiency of the programmer) and high performance
(efficiency of the program). DUNE provides, among other things, a large variety of local mesh refinement techniques, a scalable parallel programming model, an ample collection of finite element methods and efficient linear solvers.

This one week course will provide an introduction to the most important DUNE modules. At the end the attendees will have a solid knowledge of the simulation workflow from mesh generation and implementation of finite element and finite volume methods to visualization of the results. Successful participation requires knowledge of object-oriented programming using C++ including generic programming with templates. A solid background on numerical methods for the solution of PDEs is expected.

Finite Element Methods in Scientific Computing
[ more ...]

Compact Courses

Speaker: Prof. Wolfgang Bangerth
Location: INF 368, R 532
Link:

ECTS: 6

The course is intended to give students a perspective on the practical aspects of the finite element method, in particular on how typical finite element software is structured, on algorithmic details of how to efficiently implement it, and the pre- and postprocessing steps necessary in the scientific computing workflow. One of the most important lessons learned over the past decade is that due to their size, modern numerical software can’t be written from scratch for each new project, and must instead build on existing software libraries that handle most of what constitutes the finite element method as well as linear algebra and
parallel communication. Applications then only have to implement things like bilinear forms, outer nonlinear solution loops, and linear solvers specialized to the application.
The course will use a large Open Source finite element library and other open source tools for the entire workflow. The library, deal.II, can be found at http://www.dealii.org and is developed mainly at Texas A&M University in collaboration with other researchers worldwide. It is used as the standard research and teaching tool for numerical computing in the Department of Mathematics. It supports the discretization of arbitrary partial differential equations and runs on machines from laptops to supercomputers with more than 10,000 processors.
The first part of the course will be used to review the basic mathematical concepts used in this software, such as finite element theory and iterative solvers.
The rest of the course will be used for projects in which students are guided through the implementation of an application related to their research project or interests. Part of this will be teaching the use of modern software engineering practices, such as the use of revision control management systems (e.g. Subversion), writing documentation, and writing tests for automated testsuites. The goal is the development of a code that a) helps in the research of a student, and
b) may be used as the starting point for future generations of students. It may also be converted into a tutorial for deal.II.

An outline of topics to be covered is as follows:
* Basics of finite element methods
* Structure of finite element codes
* Assembling linear systems of equations and algorithmic aspects
* Iterative solvers for large linear systems
* Adaptive mesh refinement
* Vector-valued and mixed problems
* Nonlinear problems
* Postprocessing, visualization, and parallelization aspects
* Collaborative software development, e.g. through the use of subversion
* Software engineering practices for large-scale software, e.g. automated build and test systems, tools for documentation
* Additional topics may be chosen based on student interests.

This course is intended for students of mathematics involved in research.

\\\"End-to-end\\\" machine learning of image segmentation
(for neural circuit reconstruction)

Supervised machine learning is a powerful tool for creating image segmentation algorithms that are well adapted to our datasets. Such algorithms have three basic components: 1) a parametrized function for producing segmentations from images, 2) an objective function that quantifies the performance of a segmentation algorithm relative to ground truth, and 3) a means of searching the parameter space of the segmentation algorithms for an optimum of the objective function.

In this talk, I will present new work in each of these areas: 1) a segmentation algorithm based on convolutional networks as boundary detectors, 2) the Rand index as a measure of segmentation quality, and 3) the MALIS algorithm for training boundary detectors to optimize the Rand index segmentation measure. Taken together, these three pieces constitute the first system for truly \\\"end-to-end\\\" learning of image segmentation, where all parameters in the algorithm are adjusted to directly minimize segmentation error.

Public Talk

Speaker: Professor Srinivasa Varadhan
Location: INF 288, Lecture Hall 1

ECTS: 0

In this joint work with Sourav Chatterjee we consider a dense random graph with a large
number N of vertices and the edges are independently on with probability p and off with
probability 1-p. There is a law of large numbers for the number of triangles as well as for number of various finite graphs that occur in the random graph. We derive a large deviation formula for these numbers, and predict which types of graphs are responsible for these large deviations. There is an interesting phase transition. The same method can also handle large deviations for eigenvalues of random symmetric matrices. A crucial ingredient
is Szemeredi’s regularity lemma and its consequences.

Decision Support for Software Release Planning
[ more ...]

Colloquium

Speaker: Prof. Dr. Günther Ruhe
Location: INF 327, EG, SR 5

ECTS: 0

The talk is devoted to modeling, optimization methods and related tools for decision support in software release planning. Release decisions are
part of product management, an emerging discipline that aims at improving the whole process of development ranging from product requirements to design, implementation, product launch, and service. In its essence, release planning is the process of defining the functionality of a sequence of product releases as part of incremental development. Customers and stakeholders are continuously asking for more features or revision of existing ones. But: Which ones to finally select
for the next release and why? And: Which features are not attractive enough and are better left out (or postponed)? Release planning is a cognitively and computationally challenging problem because of its size, the number of stakeholders involved in it, the variety of variables that need to be looked at, and the uncertainty of the information it is relying upon. The overall goal is to determine a “most promising”
release plan such that the total degree of satisfaction of all the different stakeholders is maximized.

Dr. Ruhe (http://sern.cpsc.ucalgary.ca/~ruhe/) received a doctorate rer. nat degree (Applied Mathematics) from Freiberg University, Germany and a doctorate habil. nat. degree (Informatics) from University of Kaiserslautern, Germany. From 1996 until 2001 he was deputy director of the Fraunhofer Institute for Experimental Software Engineering Fh IESE. Since 2001, Ruhe holds an Industrial Research Chair in Software Engineering at University of Calgary. He has extensive experience in industry collaboration and technology transfer. He has organized different international conferences and workshops, has given keynotes at various conferences and has published more than 180 reviewed research papers at journals, workshops and conferences. In the area of software
release planning, Ruhe recently published a book and received a US patent. He is the Associate Editor of the Elsevier Journal Information and Software Technology IST and a member of the Editorial Board of various other journals (such as JSME and IJSEKE). He is a member of the ACM, the IEEE Computer Society, and the German Informatics Society GI.

A forward-backward algorithm for stochastic optimal control problems
[ more ...]

Talk

Speaker: Stefan Ludwig
Location: IWR, INF 368, Room 248
Link:

ECTS: 0

An algorithm for solving continuous-time stochastic optimal control problems is presented. The numerical scheme is based on the stochastic maximum principle (SMP) as an alternative to the widely studied dynamic programming principle (DDP). By using the SMP, Peng 1990 obtained a system of coupled forward-backward stochastic differential equations (FBSDE) with an external optimality condition. We extend a known numerical scheme by a Newton-Raphson method to solve the FBSDE system and the optimality condition simultaneously. As far as the authors are aware, this is the first fully explicit numerical scheme for the solution of optimal control problems through the solution of the corresponding extended FBSDE system. We discuss possible numerical advantages to the DDP approach and consider an optimal investment-consumption problem as an example.

Whole body motion planning for humanoid robots
[ more ...]

Talk

Speaker: Antonio El Khoury
Location: IWR, INF 368, room 532

ECTS: 0

This work presents a two-stage motion planner for walking humanoid robots. A first draft path is computed using random motion planning techniques that ensure collision avoidance. In a second step, the draft path is approximated by a whole-body dynamically stable walk trajectory. The contributions of this work are:
(i) a formal guarantee, based on small-space
controllability criteria, that the first draft path can be approximated by a collision-free dynamically stable trajectory;
(ii) an algorithm that uses this theoretical property to find a solution trajectory. We have applied our method on several problems where whole-body planning and walk are needed, and the results have been validated on a real platform: the robot HRP-2.

1) Statistics is sometimes not very intuitive,
2) those that do not engage themselves in the topic might easily fool
themselves or
3) ... be fooled by others.

We will speak about how to come to scientific conclusion (,,The scientific method´´ - very basic treatment), about the role of statistics in this endeavour, define _statistical significance_ and speak about its interpretations.

We then treat various paradoxa and (seemingly) unintuitive findings like the Yule-Simpson paradoxon or the Monty-Hall-Problem. Finally I will show various examples of where Statistics has gone awry - partly unintended, partly intended. The course wants to turn you into a literate reader (and producer) of basic statistics. We will also speak about how dead salmons can recognize human face expressions and why a positive HIV test or a positive indication for breast/prostrate cancers does not necessarily give a high probability that someone is actually infected/has cancer.

The lecture is intended for those of you which need to deal with understanding statitistics in literature or producing ones for your own work or just interested readers of a daily newspaper.

Join us in the CIP-Pool of the physical institute, Albert-Überle-Straße 5, 11 s.t.-12:30 and 13:00-14:30.

>>>>> There are approx 10 places left, so please let me know whether you want to come (katharina.zweig@iwr.uni-heidelberg.de). <<<<<<

If you know some fishy statistics from your own field of research, please bring it along!

ECTS: 0

Seit der Einführung des Computers als Forschungs-, Experimentier- und Prognoseinstrument erleben die Wissenschaften einen tief greifenden Wandel. Nicht nur die Praktiken und Infrastrukturen wissenschaftlichen
Arbeitens verändern sich, sondern auch die Logik der Forschung unterliegt einer grundlegenden Transformation. Neben Theorie, Experiment und Messung eröffnen Computerexperimente ein neues Feld der Wissensproduktion und verändern radikal die Experimentalkultur der Naturwissenschaften. Der Vortrag zeigt am Beispiel der Klimaforschung und der Biologie, welchen Einfluss die _in-silico_ Experimentalkultur hat.

ECTS: 4

Images are all around us! Inexpensive digital cameras, video cameras, computer web-cams, satellite imagery, images off the Internet give us access to vast numbers of spatial imagery of various sorts. The vast majority of these images will be of scenes at human scales, pictures of animals / houses / people / faces, for which countless algorithms have been developed to process / compress / segment such images, described in innumerable textbooks on image processing.

Somewhat less common, but of great research interest, are images which do allow some sort of mathematical characterization, and to which standard image-processing algorithms may not apply. In most cases we do not necessarily have images here, per se, rather spatial data sets, with one or more measurements taken over a two or higher dimensional space.

Although a great deal of research has been applied to scientific images, in most cases the resulting methods are not well-documented in common textbooks, such that many students and researchers will be unfamiliar with techniques in inverse problems, posterior sampling, and random fields.

The goal of this short course is to address methods for solving multidimensional statistical inverse problems. An outline will be provided at the start of the course.

Speaker: Dr. Carlo de Falco
Location: Prof. Rannachers group seminar room in URZ - INF294

ECTS: not yet determined

In this communication, we attempt to provide a self consistent picture, including existence
analysis and numerical solution algorithms, of the mathematical problems arising from
modeling photocurrent transients in Organic-polymer Solar Cells (OSCs). The mathemat-
ical model for OSCs consists of a system of nonlinear diﬀusion-reaction partial diﬀerential
equations (PDEs) with electrostatic convection, coupled to a ki- netic ordinary diﬀeren-
tial equation (ODE). We propose a suitable reformulation of the model that allows us to
prove the existence of a solution in both stationary and transient conditions and to bet-
ter highlight the role of exciton dynamics in determining the device turn-on time. For
the numerical treatment of the problem, we carry out a temporal semi-discretization using
an implicit adaptive method, and the resulting sequence of diﬀerential subproblems is lin-
earized using the Newton-Raphson method with inexact evaluation of the Jacobian. Then,
we use exponentially ﬁtted ﬁnite elements for the spatial discretization, and we carry out
a thorough validation of the computational model by extensively investigating the impact
of the model parameters on photocurrent transient times. Finally we discuss the applica-
bility of the numerical algorithms developed for OSCs to the simulation of another classes
of advanced devices for solar energy conversion such as the dye-sensitized electrochemical
cells.

Stochastic polynomial approximation of PDEs with random coefficients
[ more ...]

Talk

Speaker: Dr. Fabio Nobile
Location: Im Neuenheimer Feld 293, SR 215

ECTS: not yet determined

When building a mathematical model to describe the behavior of a physical system, one has often to face a certain level of uncertainty in the proper characterization of the model parameters and input data.

An example is given by the study of groundwater flow, where the subsurface permeability is largely unknown and often reconstructed from few available measurements via geostatistical techniques.

In this talk we focus on models based on Partial Differential Equations with random coefficients or forcing terms, where randomness is used to model our insufficient knowledge or intrinsic variability
of the physical system.

We first parametrize the random input data by a finite number or random variables. Then we approximate the functional dependence of the solution of the PDE on the random variables by global multivariate polynomials, exploiting the fact that such functional dependence is often highly smooth (even analytic).

We consider both Galerkin projection on polynomial spaces and Collocation type approximation on sparse grids of Gauss points. We focus, in particular, on the optimal choice of the polynomial space / sparse grid depending on the features of the differential problem at hand and the type of stochastic model for the coefficients. Our recipe for building the polynomial spaces based on a priori estimates is shown to be very effective on few numerical examples.

Image Processing on Line
[ more ...]

Talk

Location: Large Seminar Room, HCI, Speyerer Straße 6

ECTS: not yet determined

The new journal Image Processing on Line http://www.ipol.im/
publishes image analysis algorithms. Each journal article has four parts:

a) a careful text description of the algorithm on the main web page;
b) an on line demo running the algorithm in real time;
c) a non-moderated archive of all experiments performed by users;
d) a commented code in C or C++.

According to the recent statistics of the first published articles, this
format permits a quick and strong diffusion.

The publication criterion is not the novelty, but the interest to the
scientific community of certifying and diffusing the algorithm. Each
submission is carefully evaluated to ensure "reproducible research". The
scientific editors request referees to check whether a), b), c) and d)
fit perfectly or not. Indeed, the main goal is to publish certified
reference versions of algorithms.

It is hoped that this new format will foster experiment sharing, on line
benchmarks, collaborative projects and in general accelerate research by
providing certified algorithms.

This journal is in the starting phase, but some fifteen algorithms are
in course of publication and twenty more submitted. A publication
on line is different from --and complementary to-- a journal
publication. I_ll describe briefly several on line algorithms, discuss
the technical and organization challenges of such publications, and take
all suggestions.

What is Software Engineering and how can it help me in developing better software? Software has become a solid part of research in many areas like physics, biology or medicine. It is used to simulate real world situations that are often too big or too small to be handles any other way. Error in Software can have an impact on research findings and at the end get very expensive. Researchers developing software for their own use would like to spend less time coding and concentrate on their research instead. They want to be able to trust the results the software is delivering.

Software Engineering is a profession and field of study dedicated to designing, implementing, and modifying software so that it is of higher quality, more affordable, maintainable, and faster to build (wikipedia). In this course you will learn about some essential Software Engineering principles and techniques. We will take a look at the different phases in a software development process (design, implementation, testing,…). You will learn to know the 10 software engineering practices (Version management, Issue Tracking,…) every scientific software project should use.

In the practical exercises we will take a look at some freeware Tools available to accomplish the benefits we have learned about in the lectures.

Probabilistic Graphical Models --- theory, algorithms, and applications
[ more ...]

Compact Courses

Speaker: Prof. Dr. Dr. Eric Xing
Location: HCI, Speyerer Str. 6, G2.09

ECTS: 2

The past decade has seen a growing trend of applying probability theory
to machine intelligence systems that deal with complex real-world data
with rich semantic structure and temporal and/or spatial dynamics.
Probabilistic graphical model is a formalism that exploits the conjoined
talents of graph theory and probability theory to build complex models
out of simpler pieces. It offers a powerful language to elegantly define
expressive distributions under complex scenarios in high-dimensional
space, and provide a systematic computational framework for
/probabilistic inference/. These virtues have particular relevance in a
wide range of application in scientific and engineering problems such as
computational biology, robotics, information science, finance, machine
learning, etc. In this lecture series, I will discuss the basic
mathematical underpinnings of graphical models---including
representation syntax, inference algorithms, and learning strategies.
Finally I will illustrate and discuss applications of graphical models
in computer vision, informational retrieval and natural language process.

Here are the specific topics I am going to cover:

Lecture 1 : Representation: A unified view of BN and MRF
Lecture 2 : Exact Inference: HMM and CRF
Lecture 3 : Learning: Multivariate Gaussian models, Gaussian graphical
models
Lecture 4 : Complex Graphical Models: topic models for text, image, and

Good projects need money in order to be put into practice. In light of limited public funding, the securing of sources of financial support is an important task, especially in the academic sector.

Even though there is no garantueed path to reach the target, successful fundraising is not a coincidence. A prerequisite is an attractive project concept. In addition, professional skills and abilities are necessary in order to locate suitable funding sources and approach them with the right strategy.

Apart from ,,simple´ fluid mechanical or structural mechanics problems for which commercial standard solutions exist, one can find a variety of complex mathematical problems found in industrial environments. For many of these complex issues, there are generally no established simulation solutions. Appropriate mathematical and computational methods are developed in mathematical research in the industry.

In this 2-day compact course present this in more detail, starting from a variety of practical problems of industrial basic research in the field of mathematical
methods. Among other things, we will consider the following practical issues:
* Passenger flow simulation for the optimal evacuation
* The methods of the polynomial chaos
* Crack development in structures
* Topology optimization

ECTS: not yet determined

The aim for this seminar is to review a wide range of research on the subject of the title including both classical works and the work of the speaker’s research team over the past
decade. Definitions and descriptions of droplet arrays, groups, and sprays will be
presented. The classical works of the 1971-81 period will be reviewed briefly. Recent
research on transient burning and vaporization of finite arrays with Stefan convection will
be presented, including extensions to non-unitary Lewis number and multi-component,
liquid fuels. As important background information, recent results on transient, convective
burning of a single droplet will be examined. Research on transient convective burning of
infinite (doubly periodic and periodic) and finite droplet arrays will be discussed. Effects
of droplet deceleration due to aerodynamic drag, diameter decrease due to vaporization,
internal liquid circulation, and multi-step chemical kinetics will be discussed. Special
attention will be given to flame structure as a function of spacing between neighboring
droplets and Damkohler number: individual droplet flames versus group flames and wake
flames versus envelope flames. Potential future works on droplets moving in tandem,
staggered arrays, and stability of arrays will be briefly described.

Looking under the doormat - Recent ground-penetrating radar discoveries of buried structures surrounding the temples of Angkor, Cambodia
[ more ...]

Talk

Speaker: Till Sonnemann
Location: IWR, INF 368, Room 432
Link:

ECTS: 0

As part of the Greater Angkor Project, a multinational research group studying the diachronic archaeological landscape surrounding the temples of Angkor in Cambodia, ground-penetrating radar (GPR), has been extensively used in several research campaigns (2007-2010) to analyse subsurface features of the extensive water management system as well as the interior of temple enclosures.
GPR is a non-invasive geophysical survey method which offers, after the processing of data, a 3-dimensional view of the subsurface.
The survey has detected potential entry and exit channels of the giant reservoirs of Angkor, the baray, which sparked a new discussion on their function as part of the water management. Partly in combination with high resolution, but not ground-penetrating TerraSAR-X satellite radar data provided by the German DLR, the survey has revealed the existence of so far unmapped channels, enhancing our understanding of the water network at Angkor.
At Angkor Wat, a GPR survey in the enclosure has revealed the remains of a buried and demolished temple configuration that consisted of six definite and potentially as many as nine towers. They were enclosed by a rectangular wall in symmetrical alignment with the western entrance gate and the main axial causeway of Angkor Wat. Analysis of the GPR data was followed by excavations as part of the work of the Greater Angkor Project on occupation patterns in enclosures. The combined results now allow a discussion on the successive construction and demolition phases as well as occupation in the Angkor Wat enclosure.
The study indicates that the history of Angkor is not limited to its temples and what is visible on the ground. The presentation will include an introduction to the use of GPR and its functionality in Cambodia, and will provide interpretations to the most important discoveries of the survey.
Till Sonnemann (Dipl. geophys, Universität Münster, 2005) is member of the Greater Angkor Project at The University of Sydney, Australia, and PhD candidate at the university`s Department of Archaeology.

Speaker: Dr. Katharina Zweig, Dr. Sudarshan Iyengar
Location: IWR/HCI, Speyerer Straße 6, 69115 Heidelberg

ECTS: 4

In the last few years, a new interest in the understanding of networks has arisen, based on the surprising finding of some universal structures in very different networks: cooperation networks, metabolic, genetic, and protein-protein-interaction networks, electrical and neural networks, or acquaintance networks.
This course introduces the basic terminology and highlights some of the tools, methods, and measures with which networks can be characterized and analyzed. Important measures to characterize networks are, e. g., various centrality indices, the number and structure of significantly overrepresented subgraphs, or the distribution of cluster sizes. Based on these methods and measures, universal network structures and the network models that describe them will be discussed. Additionally, the behavior of some exemplary processes (disease spreading, cascading failures, robustness, etc.) in dependency of the structure will be discussed.
The course will help to understand how to characterize, describe, and model networks from all disciplines, ranging from graphical models as used in computer vision to biological or social networks.

This course is interdisciplinary and does not assume mathematical background. Thus, it is especially suitable for all students with a non-mathematical background. For those of the students with a deep interest in the mathematics behind network analysis, additional material will be available and can be discussed in detail.

Remark: The Course will be divided in two parts. Part 1 (26th-28th) will be held by K.Zweig; Part 2 (29th-30th) will be held by S.Iyengar and consist of an introduction on the topics of centrality indices and clustering algorithms.

ECTS: 2

This short course consists of two lecture series. Lecture series A provides
the fundamentals of state-space system identification to create mathematical
models from input-output measurements. In lecture series B numerical methods
for offline and online state and parameter estimation in systems of nonlinear
differential equations are presented.

The first part of lecture series A explains key linear state-space system
theory elements such as continuous and discrete-time state-space models, the
Markov parameters, observability, state estimation, various input-output
models, the Eigensystem Realization Algorithm (ERA), and the Observer/Kalman
filter Identification (OKID) method, and how these methods handle process and
measurement noises.

The second part of lecture series A deals with applications of state-space
system identification to High Performance Computing models, nonlinear system
identification with bilinear models, and identification by minimizing output
error.

Lecture series B introduces the Multiple Shooting method and the Gauss-Newton
Method for state and parameter identification in systems of nonlinear
differential equations. The Moving Horizon Estimator is presented as a
powerful method for online state and parameter estimation. Finally,
techniques for online optimal experimental design are introduced, where
incoming measurement data of a running experiment are used to plan the
remaining experiment such that the unknown parameters are determined with
minimum variances.

This short course is intended to be introductory, yet insights into these
concepts and techniques are provided whenever possible for research purpose.
No advanced knowledge on the subject is assumed.

Multiconfigurational Time-Dependent Hartree Methods: Past, Present, and Prospects
[ more ...]

Seminar

Speaker: Prof. Ofir E. Alon
Location: TC, PCI, INF 229, 1st floor, Room 108/110

ECTS: 0

The multiconfigurational time-dependent Hartree (MCTDH) method
is considered at present the most efficient wave-packet
propagation approach for systems of distinguishable
degrees-of-freedom, like molecular vibrations, etc. It was
invented in Heidelberg 20 years ago by H. D. Meyer, U. Manthe,
and L. S. Cederbaum, and has since led to a mirage of exciting
scientific advancements in "Quantum Dynamics". In recent years,
there have been ongoing scientific activities to extend the
MCTDH method to be applicable and efficient for physical
systems made of indistinguishable particles. For systems made
of electrons (fermions) the MCTDH for fermions (MCTDHF) was
developed whereas to describe the quantum dynamics of
interacting cold atoms (bosons) the MCTDH for bosons (MCTDHB)
was developed. These have opened the door to an intricate,
reliable, and accurate many-body non-equilibrium physics of
interacting particles beyond the classical text-book models of
the Hartree-Fock approximation for fermions and
Gross-Pitaevskii equation for bosons.

In my extended seminar at the HGS/MathComp I will open with a
general, unified description of multiconfigurational
time-dependent Hartree methods for systems of identical
particles and mixtures thereof, and elaborate on the utilization
of field operators, reduced-density matrices, and the
time-dependent variational principle to derive a compact and
efficient-to-work-with set of the equations of motion.

In the next part I will review some of the exciting applications
and breakthroughs achieved with MCTDHB in the prediction of
many-body phenomena of Bose-Einstein condensates. The concept of
condensate fragmentation will be defined and shown to dominate
the physics of Bose-Einstein condensates in many physical
scenarios, previously thought not to involve fragmentation at
all.

What lies ahead of us in the deciphering and description of
non-equilibrium dynamics of complex many-body quantum systems?

All quantum systems we have dealt with so far in my talk -- and
for which multiconfigurational time-dependent Hartree methods
have been developed and implemented -- assume the number of
particles (molecular vibrations, electrons, or cold atoms) in
the system to be conserved. However, there are many quantum
systems in which particles_ conversion, i.e., the
"transformation" of particles of one kind to another, governs
the basic behavior of the physical system under investigation.
These include "chemical reactions", transitions between
hyperfine states in ultracold atoms, and association and
dissociation of electrons to Cooper-pairs in solid-state
targets. Using the theoretical tools presented above I will
present the extension of the standard, particle-conserving
multiconfigurational time-dependent methods to systems with
particles_ conversion. I will conclude my seminar with a
discussion of prospects and future plans along the
"multiconfigurational time-dependent way" to researching the
quantum dynamics around us.

What is Software Engineering and how can it help me in developing better software? Software has become a solid part of research in many areas like physics, biology or medicine. It is used to simulate real world situations that are often too big or too small to be handles any other way. Error in Software can have an impact on research findings and at the end get very expensive. Researchers developing software for their own use would like to spend less time coding and concentrate on their research instead. They want to be able to trust the results the software is delivering.

Software Engineering is a profession and field of study dedicated to designing, implementing, and modifying software so that it is of higher quality, more affordable, maintainable, and faster to build (wikipedia). In this course you will learn about some essential Software Engineering principles and techniques. We will take a look at the different phases in a software development process (design, implementation, testing,…). You will learn to know the 10 software engineering practices (Version management, Issue Tracking,…) every scientific software project should use.

In the practical exercises we will take a look at some freeware Tools available to accomplish the benefits we have learned about in the lectures.

Information visualization can be invaluable in making sense
out of large data sets. However, traditional graph visualization methods
often fail to capture the underlying structural information, clustering,
and neighborhoods. Our algorithm for visualizing graphs as maps
provides a way to overcome some of the shortcomings with the help of the
geographic map metaphor. While graphs, charts, and tables often require
considerable effort to comprehend, a map representation is more
intuitive, as most people are very familiar with maps and even enjoy
carefully examining maps. The effectiveness of the algorithm is
illustrated with examples from several domains: TV shows, movies, books,
and music.

Public Talk

Speaker: Prof. Lloyd N. Trefethen
Location: KIP, Lecture Hall 2, INF 227
Link:

ECTS: 0

New date and place

For a long time there have been two kinds of mathematical computation: symbolic and numerical. Symbolic computing manipulates algebraic expressions exactly, but it is unworkable for many applications since the space and time requirements grow combinatorially. Numerical computing avoids the combinatorial explosion by rounding to 16 digits at each step, but it works just with individual numbers, not algebraic expressions.

This talk will describe a new kind of computing that aims combines the feel of symbolics with the speed of numerics. The starting idea was to represent functions by Chebyshev expansions whose length is determined adaptively to maintain an accuracy of close to machine precision. The chebfun system is implemented in object-oriented Matlab, with familiar vector operations such as sum and diff being overloaded to analogues for functions such as integration and differentiation. But by now, the capabilities of chebfun have developed far beyond what this short description may suggest -- including, for example, the high-precision automatic solution of linear and nonlinear differential equations by executing "backslash". Chebfun is a joint project with Rodrigo Platte, Nick Hale, Toby Driscoll, Ricardo Pachon, and others.

ECTS: 0

Scientific discoveries in the natural sciences are increasingly data-driven and computationally intensive, providing unprecedented data analysis and scientific computing challenges and opportunities. Scientific workflow systems and tools aim at simplifying the process of designing, executing, and maintaining complex "code aggregates", i.e., consisting of, e.g., a mix of simulation, data management, analysis, and visualization steps. Thus, scientific workflows target similar use cases as do scripting languages such as Perl or Python and can be seen as the "glue" for assembling and executing complex computational science experiments from pre-existing tools and programs. In addition, scientific workflow systems can provide further functionality, e.g., to capture the "provenance" (i.e., processing history and data lineage) of workflow outputs, thus allowing scientists to interpret, debug, and reproduce their computational experiments, or to provide fault-tolerance and scalability for well-designed scientific workflows.

In this talk, I will give an overview of this new and active research area, using real-world examples to illustrate the potential as well as current limitations of scientific workflow technology. At the end, I will also provide an overview of a course on scientific workflow management that will start one week after this talk. The course is aimed at both practitioners, i.e., computational scientists, bioinformaticians, etc. who would like to learn more about new (and possibly different) ways to think about their workflow automation tasks, and at computer scientists who are looking for application-oriented research problems that can make a difference for their colleagues in the natural sciences.

Speaker: Avshalom Karasik
Location: IWR, INF 368, Room 532

ECTS: not yet determined

The Computerized Archaeological Laboratory, at the Hebrew University of Jerusalem started to operate on January 1st 2010. Its purpose is to harness mathematical and computational methods to support archaeological research, documentation and visualization. The laboratory is equipped with modern, high precision scanners which provide digital three dimensional models of archaeological finds. We concentrated on ceramic and lithic artifacts, and developed several tools and algorithms which are used routinely as the standard procedure for their analysis and publications. The presentation shall summarize the main novel features which are relevant to ceramics:
1) Efficient, high precision data acquisition using 3D scanners.
2) A stable and reliable algorithm which automatically finds the symmetry axis of pottery fragments.
3) A user friendly interface which creates print quality drawings of the objects.
4) A new procedure for automatic typology and classification of ceramic assemblages, which is based on mathematical representations of the cross-section profiles.
These four steps of documentation and analysis are now the routine tasks in the lab. So far we have successfully tested the procedure for more than 10,000 fragments from a large variety of archaeological excavations.

ideals.
It turns out that all symbolic powers are Cohen-Macaulay if and only
if the associated simplicial complex is a matroid. This result leads

Soot Formation Modeling
[ more ...]

Talk

Speaker: Dr. Iliyana Naydenova
Location: IWR, INF 368, Room 532
Link:

ECTS: 0

Numerous mechanisms for soot formation are known, capable for describing soot formation under specific conditions, but just a few have been developed for describing soot formation in various combustion systems. A detailed kinetic model has been developed and validated against the experimentally obtained concentration profiles of the main gas-phase species, measured in shock tube experiments and soot particle characteristics.

For the application in a multi-dimensional computational fluid dynamics (CFD) code for turbine combustion simulation, merely simple empirical models with few variables must be used. Therefore, a two-equation model has been developed for simulation of time-dependent homogeneous reaction systems. The model has been calibrated by the reaction kinetics of the detailed chemical mechanism. The complex phenomenon of soot formation is described in terms of several global steps: inception, growth, coagulation and oxidation, where two differential equations are solved for the temporal change of soot concentration and soot volume fraction.

ECTS: 3

Mixed-Integer Nonlinear Programming (MINLP) is a sub-field of Mathematical Programming (MP) specializing in modelling and solving one of the most general (and hard) classes of optimization problems: namely, problems including both nonlinear terms and integer variables. There are countless applications: in energy production, chemical engineering, scheduling, software verification, quantum chemistry, geometry, bioinformatics, nuclear engineering, and water distribution, to name a few.

Small and medium scale MINLPs are currently solved using a Branch-and-Bound variant called "spatial Branch-and-Bound" (sBB), where branching is allowed on continuous as well as discrete variables that contribute to the gap between the original problem and its convex relaxation. For large-scale variants one must currently resort to heuristics, such as VNS, Feasibility Pump, Local Branching; or exploit the problem structure to derive special-purpose methods.

Such special-purpose methods need to be applied, when the processes to be optimized are time-dependent. Mixed-integer optimal control problems (MIOCPs) are formally more general than MINLPs, but after a certain way of discretization a subclass of MINLPs with specific features that need to be exploited.

We revise many of these methods in theoretical lectures and apply them to challenging problems in afternoon hands-on practical exercises in the computer pool.

Understanding Solid-Gas Interfaces and Developing Next-generation Electrodes
[ more ...]

Talk

Speaker: William C. Chueh
Location: IWR, INF 368, Room 532
Link:

ECTS: 0

Solid-gas interfaces are crucial in a wide variety of electrochemical systems,
such as fuel cells, electrolyzers, and air batteries. Electrode reactions occurring
in these devices involve ions, electrons and gas-phase species and take place
across multiple surfaces, such as those of metals, semiconductors, and ionic
conductors. Improving electrode reactions rate are critical for increasing energy
conversion efficiencies, lowering system costs, and eliminating the use of
precious materials. In the first half of the talk, I will discuss new insight into the
reaction pathways for nickel-doped cerium oxide composite fuel cell anodes.
Lithographically patterned thin film structures and two-dimensional electrostatickinetics
models were employed to decouple multi-phase reaction-diffusion
interactions. These insights enabled the design and fabrication of several highperformance
anode microstructures. In the second half of the talk, I will present a
novel cerium oxide-based thermochemical cycle for dissociating H2O and/or CO2
into H2, CO, CH4 or synthesis gas at record rates. In this cycle, cerium oxide is
first thermally reduced and then reoxidized by H2O and/or CO2 at a lower
temperature to produce fuel(s). The unfavorable deposition of carbon on the
surface of cerium oxide can be readily manipulated, in conjunction with a base
metal catalyst, to tune the selectivity of the products.

Multi-scale modeling and simulation of complex chemical reaction networks
[ more ...]

Compact Courses

Speaker: PD Dr. Dirk Lebiedz
Location: IWR, Room 432

ECTS: 4

Differential equation models involving detailed chemical reaction kinetics inherently share a multi-scale character and often a huge state space dimension. Reaction dynamics on multiple time scales generally couple to physical transport such as diffusion or convection. Realistic modeling and numerical simulation are necessary for mechanistic understanding, model-based optimization and control of chemical processes and require the use of highly efficient scientific computing methods exploiting the multi-scale character of these problems. Theoretical and numerical aspects as well as applications of multiple time scale chemical kinetic models will be discussed in the lecture course.

Computational Biology - One Modelling Formalism & Simulator is not enough!
[ more ...]

Lecture

Speaker: Professor Dr. rer. nat. Adelinde M. Uhrmacher
Location: IWR, INF 368, Room 432

ECTS: 0

Diverse modelling formalisms are applied in Computational Biology. Some describe the biological system in a continuous manner, others focus on discrete-event systems, or on a combination of continuous and discrete descriptions. Similarly, there are many simulators that support different formalisms and execution types of one and the same model.
The latter is often done to increase efficiency, sometimes at the cost of accuracy and level of detail. JAMES II has been developed to support different modelling formalisms and different simulators and their combinations. Its focus is on discrete event simulation and it is based on a plug-in concept which enables developers to integrate spatial and non-spatial modeling formalisms, simulation algorithms and supporting technologies into an existing framework. This eases method development and result evaluation in applied modelling and simulation as well as in modelling and simulation research. Based on different Gillespie variants it is shown how the plug-in concept in James II supports the implementation, evaluation, and on demand configuration of simulation algorithms.

Location: ICM, Warshaw, Polen

ECTS: 0

Due to the revolutionary new technologies that have arisen in the field of biological data collection, an enormous amount of information on a molecular and cellular scale has become available and much has been learned about the molecular components involved in signal transduction during normal and pathological development. Such progress is producing a growing need to quantitatively understand and manipulate this data and translate it into practical applications. Researchers in computational and theoretical biology are using a variety of mathematical approaches to understand and manipulate biological processes.

This workshop is devoted to multiscale aspects of mathematical modelling and analysis of transport processes and regulatory feedbacks in cell systems. Recent results and theoretical methods from multiscale analysis and nonlinear dynamics will be discussed in the context of applications to the study of the collective properties of biological systems.

The main topics to be studied are:
Models for cell differentiation and transformation
Models of the transport processes in a complex medium

The workshop is organised within the framework of the Polish-German Graduate College (Research Training Group 710), Heidelberg Graduate School of Mathematical and Computational Methods for the Sciences and International PhD Programme (MPD).

Finite-Time Lyapunov Timescale and Stability Analysis: Application to Optimal Control
[ more ...]

Lecture

Speaker: Prof. Dr. Ken Mease
Location: IWR, INF 368, Room 432

ECTS: 0

Hyper-sensitivity to unknown boundary conditions is a well-known issue for indirect shooting methods in solving optimal control problems. This feature may however imply an underlying geometric structure in the state-costate space for the flow of the corresponding Hamiltonian system. This geometric structure suggests a solution approximation strategy that eliminates the hyper-sensitivity. To exploit this opportunity requires placing initial and final points on certain invariant manifolds. Finite-time Lyapunov analysis is used to quantify the hyper-sensitivity and determine the tangent space geometry. Then the tangent space geometry is used to define properties of points on the invariant manifolds of interest. A simple example is used to illustrate the approach.

How a 12th Century Angkorian Monument in Cambodia undergoes restoration using traditional skills and innovative technology.

John Sanday is a British architect who has spent the last 35 years living and working in Asia. As one of the region’s leading architectural conservators, he has travelled and worked all over the sub-continent on a wide and varied assortment of archaeological sites, historic buildings, monasteries in the high Himalaya, palaces in India, and, since 1989, in the Angkor complex in Cambodia. For his long term dedication to architectural conservation and training in Asia, John was awarded the Order of the British Empire (OBE) by Her Majesty Queen Elizabeth II in the honours list of 2006.

The title of my contribution is “Mathematical Function Evaluation in High Performance Computing” :
- A new “Chebyshev Algebra”, yielding a comprehensive set of optimal polynomial approximations for the elementary functions;
- VML (Vector Math Library), a set of ITANIUM codes for mass production of elementary functions. These VLM codes were implemented as “two-core” codes, running two parallel threads for two arguments; adapting these codes for a multi-core computer with GPU-s seems obvious.

Geometry for Reassembling Fractured Objects
[ more ...]

Talk

Speaker: Dr. Michael Hofer
Location: IWR, INF 368, R. 520

ECTS: 0

In Archaeology it is often necessary to reassemble
fractured objects. Due to the large number of parts,
the size of the individual broken pieces, or a possible dislocation to different parts of the world
(excavation site, museums, ...), a digital reassembly
may be very useful. In this talk I will present a system for automatically reassembling broken 3D solids.
Using techniques that belong to geometry processing,
3D digital models of the fragments are first geometrically
analyzed. Then, using a variety of methods matching pieces are identified. Using constrained optimization
they are mutually registered into their respective spatial position in the unbroken object. Illustrative
examples showing the effectiveness of the algorithm
include matching pieces of the Forma Urbis Romae and the Octagon in Ephesus.

A Tale of Two Problems: Integer and Nonlinear Optimization
[ more ...]

Talk

Location: IWR, INF 368, 4th floor, room 432

ECTS: 0

Many scientific and engineering applications involve both discrete decisions and nonlinear dynamics that affect the optimality of the final design. Mixed-integer nonlinear programs (MINLPs) combine the difficulty of discrete variable sets with the challenges of nonlinear functions. The discrete components of an MINLP model phenomena such as fixed charges, dichotomies, and general logical relationships. Nonlinearities often describe phenomena such as covariance, economies of scale, or physical properties such as pressure, stress, and equilibrium. We survey recent advances in branch-and-cut methods that have resulted in the new solver FilMINT.

The dynamics of liquid droplets driven by induced polarization effects was studied both experimentally and theoretically. During experiments droplets were isolated from all other effects using microgravity environment. The evolution of droplets was captured using a high-speed movie camera. Theoretical analysis, which involved numerical simulation of the deforming droplet, was able to reproduce various stages of the deformation process in time up to the formation of Taylor cones.

ECTS: 3

In many areas of science and engineering numerical simulation is an
important tool for research and development. Current simulation
trends range from multiscale-/multiphysics modelling to the usage of
parallel machines with PetaFlops performance. The Distributed and
Unified Numerics Environment (DUNE) tries to fit these
heterogeneous requirements inside a single environment with novel
numerical techniques as well as state-of-the-art software development
methods.

By participating in this course scientists have the opportunity to get
a hands-on introduction to the DUNE framework. Main focus is to give a
detailed introduction to the DUNE core modules: the grid interface
including IO methods with its numerous grid implementations and the
iterative solver module ISTL. In the exercises elliptic and hyperbolic
model problems will be solved with various methods.

Acoustic Optimization of Plates and Shells
[ more ...]

Talk

Speaker: Sean Hardesty
Location: INF368, Room 532

ECTS: 0

Modeling of elastic shell structures coupled with acoustics in a way
that is suitable for optimization poses a multitude of challenges. For
the exterior problem, it is convenient to use shell elements in
conjunction with boundary elements so that shape updates can be
performed without modifying the mesh. In order to do so, the shell
code must be free of the so-called locking phenomenon, and the
boundary element code must be robust and reasonably fast. With the aim
of making the implementation of the coupling and adjoint equations as
simple as possible, we describe a scheme satisfying these criteria,
and present some numerical results.

Computation of Polarization Resistance in Samaria Doped Ceria
[ more ...]

Talk

Speaker: Francesco Ciucci
Location: IWR, Raum 532

ECTS: 0

Samarium Doped Ceria (SDC) electrodes are currently of great interest for SOFC applications. For example, ceria-containing anodes can be operated directly on hydrocarbons without coking, and in addition can be used at lower temperatures than Ni/YSZ. In order to design, optimize, and characterize electrodes, it is very useful to have models to aid in interpreting experimental results. In this work, we present a linear, time-independent model for the study of SDC. This model allows us to compute species concentrations, electric potential and currents under small bias conditions. A regular perturbation of the drift diffusion equations and Poisson’s equation is used to derive the model for the behavior of bulk of the material. We also include the kinetics of reactions occurring at the SDC-gas surface where the SDC is exposed to a spatially uniform hydrogen-water-argon mixture at fixed total pressure. The linear response to a small voltage input is computed at various hydrogen and water partial pressures.
The numerical procedure allows for fast computations and for the direct determination of fast and rate limiting steps. Polarization resistance curves are computed in the two dimensional case and a quantitative comparison between experimental (symmetric cell) and numerical results computations is presented.
The model can be naturally extended to the non-symmetric case, i.e. the case under which the two sides of the SDC assemblies are exposed to different atmospheres.

Automated 3D-Acquisition and Documentation of Archaeological Finds,
[ more ...]

Talk

Speaker: Hubert Mara
Location: INF 368, Raum 432

ECTS: 0

Abstract:
Motivated by the requirements of today’s archaeologists we are developing a system for documentation of daily finds of excavations using 3D-acquisition. The most widespread finds are fragments of ceramics, shortly called sherds. As ceramics have been produced for millenniums and found in vast numbers, their fragments are important for archaeological research, because their shape leads to information about ancient cultures.

We show the use of 3D-Scanners based on the principle of structured light for documentation. This enables an accurate and efficient way of in-situ acquisition. Using the common feature of rotational symmetry of ceramics typically produced on rotational wheels, we can automatically estimate proper orientated cross-sections (profiles) of the acquired sherds for archaeological publications and classification. Having 3D-models of ceramics we can also determine additional information about the manufacturing process, quality features or volume estimations for further classification.

Beside geometric features, ceramics and other objects of our Cultural Heritage have painted decoration and today’s 3D-scanners are able to acquire coloured (textured) surfaces. Future work requires to add texture-analysis and pattern recognition methods for 3D-documentation as well as high-resolution texture mapping and handling techniques e.g. from multi-spectral imaging. Pattern recognition will also help to organize the 3D-documenation using Semantics and Digital Libraries. We will show examples from several inter-disciplinary projects with archaeological partners in Austria, Israel, Italy, Germany and Peru.

Numerical simulation of a fully-nonlinear free-surface flow and its applications on the studies of microscale dynamics in the upper oceans
[ more ...]

Talk

Speaker: Dr. Li-Ping Hung
Location: INF 229, Seminar Room 108/110

ECTS: 0

A numerical model for simulating a three-dimensional flow bounded by a fully-nonlinear, free-surface boundary is developed. The free-surface boundary conditions are satisfied on the free-moving surface exactly without any approximation or linearization. The governing equations and the boundary conditions on the time-dependent, physical domain are transformed onto a regular domain for numerical computations. The solenoidal condition of the velocity field is satisfied by solving the transformed pressure Poisson equation. A modified secant method is used to accelerate the iterative solution of the non-separable Poisson equation. We first apply the numerical model to study the development and evolution of parasitic capillary ripples on a two-dimensional gravity-capillary wave. The simulation results reveal that strong vortices are shed from the troughs of the capillary ripples, convected backward, and form a strong boundary layer. As a result, energy dissipation is enhanced with the generation of parasitic capillaries. The model capabilities for resolving nonlinear interactions among the surface waves are then demonstrated by simulating the three-dimensional evolutions of the short-crested waves and the crescent waves. Finally, the developed model is applied to simulate a wind-driven turbulent boundary layer bounded by a dynamic water surface. The simulation results reveal fine surface structures, including parasitic capillary waves developed from the front face near the crest of the dominant gravity wave and streamwise velocity streaks on the back gravity-wave surface, which have been observed in the laboratory and field experiments.
