A simulation is reliable when the simulation time is much longer than the relaxation time of the quantities in question. The aim of this work is to address the question when Molecular Dynamics (MD) simulation is reliable and how it depends on the integration algorithms and optimal time step. There were certain problems related to the choice of integration algorithms on Molecular Dynamics simula...

As the speed and payload of Wheeled Mobile Robots (WMRs) increases and the clearances between obstacles and docking error tolerances decreases, methods for reducing tracking errors become increasingly important for a successful application. In this paper techniques and results are presented for improved tracking control of a WMR through the generation and dynamic simulation of paths with and wi...
