Supervised by Erwin Stein, "Verteilte Algorithmen für h-, p- und d-adaptive Berechnungen in der nichtlinearen Strukturmechanik", Hannover, June 2001

The overall goal of this work is to bring together a number of problem solutions in the areas of computer science, numerical methods, and mechanics to an h-, p-, and d-adaptive dynamically load balanced and completley parallelised Finite Element Program.

Supervised by Karsten Steffens, "Partitionen unendlicher Mengen", Hannover, May 1993.

The central focus of this work is a proof of the theorem: For any partition {p0, p1} of NxN there exists an infinite subset M of N such that either p0 or p1 contains MxM.

Highly Recommended Award 2010 from EmeraldLiteratiNetwork for the paper "Multi-scale modelling of heterogeneous structures with inelastic constitutive behavior. Part II - software coupling implementation aspects" in the journal Engineering Computations vol. 26,1 and 2, 2009

"Verfahren zur komprimierten Speicherung von Triangulationsdaten", DE10116275A1, 17.10.2002

This procedure reduces the memory amount for the connectivity of a triangular mesh below one bit per triangle.
