Based on a discrete version of this principle, a structure preserving time-stepping scheme is derived. It is shown that this respect for the mechanical structure (such as a reliable computation of the energy and momentum budget, without numerical dissipation) is retained when the system is reduced to its minimal dimension by the discrete null space method. Together with initial and final conditions on the configuration and conjugate momentum, the reduced time-stepping equations serve as nonlinear equality constraints for the minimisation of a given cost functional. The algorithm yields a sequence of discrete configurations together with a sequence of actuating forces, optimally guiding the system from the initial to the desired final state. The resulting discrete optimal control algorithm is shown to have excellent energy and momentum properties, which are illustrated by two specific examples, namely reorientation and repositioning of a rigid body subject to external forces and the reorientation of a rigid body with internal momentum wheels.}}, author = {{Leyendecker, Sigrid and Ober-Blöbaum, Sina and Marsden, Jerrold E. and Ortiz, Michael}}, booktitle = {{Volume 5: 6th International Conference on Multibody Systems, Nonlinear Dynamics, and Control, Parts A, B, and C}}, isbn = {{079184806X}}, title = {{{Discrete Mechanics and Optimal Control for Constrained Multibody Dynamics}}}, doi = {{10.1115/detc2007-34574}}, year = {{2007}}, } @inbook{16640, author = {{Monien, Burkhard and Preis, Robert}}, booktitle = {{Mathematical Foundations of Computer Science 2001}}, isbn = {{9783540424963}}, issn = {{0302-9743}}, title = {{{Upper Bounds on the Bisection Width of 3- and 4-Regular Graphs}}}, doi = {{10.1007/3-540-44683-4_46}}, year = {{2007}}, } @article{16648, author = {{Padberg, Kathrin and Hauff, Thilo and Jenko, Frank and Junge, Oliver}}, issn = {{1367-2630}}, journal = {{New Journal of Physics}}, pages = {{400--400}}, title = {{{Lagrangian structures and transport in turbulent magnetized plasmas}}}, doi = {{10.1088/1367-2630/9/11/400}}, year = {{2007}}, } @inproceedings{16651, author = {{Zukic, D. and Elsner, A. and Avdagic, Z. and Domik, Gitta and Schäfer, W. and Boskovic, D. }}, location = {{Bosnia Herzegovina}}, title = {{{Neural Networks in CT scan Visualization}}}, year = {{2007}}, } @inbook{16658, author = {{Preis, Robert and Monien, Burkhard and Schamberger, Stefan}}, booktitle = {{Handbook of Approximation Algorithms and Metaheuristics}}, isbn = {{9781584885504}}, issn = {{2154-4573}}, title = {{{Approximation Algorithms for Multilevel Graph Partitioning}}}, doi = {{10.1201/9781420010749.ch60}}, year = {{2007}}, } @inproceedings{16666, author = {{Schütze, Oliver and Talbi, El-ghazali and Pulido, Gregorio Toscano and Coello, Carlos Coello and Santana-Quintero, Luis Vicente}}, booktitle = {{2007 IEEE Swarm Intelligence Symposium}}, isbn = {{1424407087}}, title = {{{A Memetic PSO Algorithm for Scalar Optimization Problems}}}, doi = {{10.1109/sis.2007.368036}}, year = {{2007}}, } @article{1672, author = {{Krimphove, Dieter}}, journal = {{EuR Europarecht}}, number = {{Heft 5, Jg. 42}}, pages = {{597 ff.}}, title = {{{Gesetzgebung im Europäischen Bank- und Kapitalmarktrecht - eine ökonomisch-historische Betrachtung}}}, year = {{2007}}, } @inproceedings{16864, author = {{Schwier, M. and Domik, Gitta and Fricke, E. and Götz, F. and Fricke, H. and Weise, R. and Burchert, W.}}, location = {{Hannover}}, title = {{{Interaktive 2D-Transferfunktionen zur Visualisierung und Auswertung von CT/PET Datensätzen}}}, year = {{2007}}, } @inproceedings{16865, author = {{Fricke, H. and Schwier, M. and Weise, R. and Van den Hoff, J. and Fricke , E. and Burchert, W. and Domik, G.}}, booktitle = {{45.
