info  Women in Optimization Prof. Dr. Katja Mombaur March 2-4, 2015 ECTS-Points: 0
Abstract, registration & information:
The workshop targets female junior researchers, PhD students and students of Mathematics with a focus on optimization. The goal of the workshop is to provide advanced scientific training in the field of optimization as well as an opportunity for networking in the optimization community. By lectures of invited speakers working in all areas of optimization in academia and industry we want to present on the one hand a wide scientific spectrum of topics in mathematical optimization as well as different possible career models in this field. In addition to these lectures there will be ample opportunities for discussions and an exchange of experiences. All participants are invited to actively participate in poster presentations.

Abstract, registration & information:
Targeted Audience: MS & PhD students in the beginning semesters of their research (Dissertation/thesis)

Workshop Objectives:
- To introduce to the participants the objectives of MS/PhD research in order to enable them in targeting these objectives more cautiously and from the outset of their study programme.
- To share the various processes and timeframes which are crucial to understand for a smooth beginning and completion. For example the process and time frames for degree programme, research project, research write-up.
- The workshop also aims at sharing useful tips in pushing through different stages and challenges and in pointing out certain pitfalls that every researcher must avoid. Moreover, it will draw attention towards some essential skills needed by a researcher at this level.

Workshop Nature & Plan:
- A multimedia / presentation based interactive workshop interspersed with classroom questioning and discussion.
- One hour and thirty minutes will be dedicated to Resource Person led inputs in the session.
- Final thirty minutes will be devoted to questions from the audience.

info  Bilevel Optimal Control - Combining Theoretical and Numerical Approaches Various Speakers October 20-22, 2014 ECTS-Points: 0
Abstract, registration & information:
The workshop is concerned with the theory and the numerics of bilevel optimal control problems, which are optimal control problems, mainly in ordinary differential equations, with two levels of optimization. We intend to discuss theoretical aspects like optimality conditions and stationarity concepts of this problem class, but we are also concerned with the development of efficient solution algorithms and the corresponding convergence theory. Furthermore, challenging applications from fields like image processing, medicine or robotics are presented.

Abstract, registration & information:
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.

info  A discrete variational approach to hybrid dynamical systems and optimal control Prof. Sigrid Leyendecker 16 October 2014, 14:15h ECTS-Points: 0
Abstract, registration & information:
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.
