Johannes Kepler Symposium on Mathematics

As part of the Johannes Kepler symposium on mathematics Prof. Dr. Ralf Kornhuber, Institut für Mathematik II, FB Mathematik und Informatik, Freie Universität Berlin, will give a public talk (followed by a discussion) on Wed, Dec. 12, 2007 at 15:45 o'clock at HS 9 on the topic of "First steps towards the human gait" . The organziers of the symposium,

O.Univ.-Prof. Dr. Ulrich Langer,
Univ.-Prof. Dr. Gerhard Larcher
A.Univ.-Prof. Dr. Jürgen Maaß, and
die ÖMG (Österreichische Mathematische Gesellschaft),

hereby cordially invite you.

Series A - General Colloquium:

The intention is to present general information not only to experts, but also to students and guests from outside the mathematical institutes.

First steps towards the human gait

A precise prediction of loads and forces within human joints would support surgical decisions and thus increase the overall success of surgery procedures. However, in vivo measurements are hardly possible and credible numerical simulation is demanding task. In this talk, we consider 3D finite element models of the human knee and particularly concentrate on efficient and reliable multigrid solvers for the arising two body contact problems, heterogeneous domain decomposition methods for the coupling/decoupling of bones and ligaments and contact-stabilized time discretizations.
