HGS MathComp Curriculum & Events

The 2018 German Chapter Conference of the European Women in Mathematics, organized by UPSTREAM - The Network for Women in Maths, Heidelberg, and the Konstanz Women in Mathematics: Paths in Studies and Career (KWIM), is a space supporting women in their careers and giving them prominence and visibility, the conference follows the EWM tradition since its foundation in 1986.

The aim of this conference is to promote communication and networking between mathematicians from all research areas, offering in particular a platform to female mathematicians at all academic stages for presenting their mathematical results, sharing their experiences and discussing the challenges related to the gender gap in this field.

The scientific programme will consists of one-hour talks by four keynote speakers, shorter contributed talks to be presented in parallel thematic sessions, and a poster session with one-minute presentations for each poster. The programme will include an invited talk on gender balance in academia encouraging active discussion among the participants about this issue for mathematicians in Germany.

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.

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.

! Die Veranstaltung ist öffentlich. Der Eintritt ist frei. Um Anmeldung bis zum 1. Juli 2018 wird gebeten !

Laser scanning efficiently samples our urban and natural environment. LIDAR systems on tripods, cars, drones, planes and even backpacks are able to collect billions of 3D points in a few hours. What remains challenging is to automatically extract valid geometric information from these points clouds in a similarly efficient way. In the presentation issues with these point clouds will be discussed, followed by some overview of methods to extract geometric information on e.g. trees, traffic signs, tunnels or beaches in a robust and computationally efficient way.

The Molecular Sciences Software Institute (MolSSI) is a nexus for science, education, and cooperation serving the worldwide community of computational molecular scientists - a broad field including of biomolecular simulation, quantum chemistry, and materials science. The Institute focuses on the software infrastructure, education, standards, and best-practices that are needed to enable the molecular science community to open new windows on the next generation of scientific Grand Challenges, ranging from the simulation of intrinsically disordered proteins associated with a range of diseases to the design of new catalysts vital to the global chemical industry and climate change. The MolSSI is working to enable the computational molecular sciences community to work together to leverage its diverse capabilities that will reduce or eliminate the gulf that currently delays by years the practical realization of theoretical innovations. Ultimately, the Institute will enable computational scientists to tackle problems that are orders of magnitude larger and more complex than those currently within our grasp. This lecture will provide an overview of the Institute’s activities, goals, and vision.

Quasi-experiments offer opportunities for strong causal inference for evaluation of real-life programs and policies.

I will discuss major approaches and illustrate strengths and limitations with examples.

Vortrag anlässlich des 70. Geburtstags von Prof. Dr. Dr. h.c. mult. Hans Georg Bock.

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.

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.

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.

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.

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.

?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.

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.

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.

Prof. Fox is the most recently appointed Romberg Visiting Scholar at the HGS MathComp.

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.

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.
