Harald Biller studied mathematics and physics at Darmstadt, London, and Würzburg. In 1999, he received his PhD from Stuttgart University, specializing in functional analysis, topology, and Lie theory. He worked as a lecturer at Darmstadt University until 2004, when he became a ... En savoir plus
Thomas Herrmannsdörfer got his PhD in experimental physics from the University of Bayreuth in 1994. In 1995, he received the Research Award of the Emil-Warburg-Foundation while he worked at the DFG-Graduiertenkolleg Bayreuth. From 1995 – 1998 he worked as a scientist at Hahn-Meitner ...

Particle-particle interactions are usually neglected when considering the behaviour of magnetic particle's so called magnetic beads in e.g. a microfluidic device. However, if the particle density exceeds a critical limit, this assumption might not lead to proper results anymore. In this ... En savoir plus
Cogging torque in permanent magnet motors and generators is characterized by a torque ripple. These torque fluctuations cause vibrations, noise and speed fluctuations. This paper presents finite element (FE) analyses results that show a previously unaddressed low frequency modulation of ... En savoir plus
Finite element modeling of three-phase induction machines requires the solution of coupled circuit and field equations. This work aims to solve this problem using a strong coupling approach. This work includes circuit field coupling and proper air-gap meshing, using the AC/DC Module of ... En savoir plus
A simple proximity sensing circuit is made using magnets actuating reed switches; these switches are wired into a larger circuit that performs auxiliary functions. The success or failure of such systems is a function of their position. A simulation using COMSOL Multiphysics is conducted ... En savoir plus
Tunnels and their detection have been a problem in warfare since the ancient world. Recent events have highlighted the ongoing problems of tunnels and the difficulties in locating them, not only in military situations, but also in law enforcement and homeland security applications as ...

This paper describes the automatic optimization of an electromagnetic actuator using a genetic algorithm. The actuator modeled here is dedicated for charge changing valve actuation in internal combustion engines. In the first step of the simulation, several operating points are ... En savoir plus
In this paper an electromagnetic solenoid actuator (EMVA) consisting of an upper and lower electromagnet, a linear moving armature and two preloaded springs is considered as a potential approach in Variable Valve Actuation (VVA) Systems for Internal Combustion Engines. In opposition to ... En savoir plus
Markus Zahn received all his education at MIT, was a professor in the Department of Electrical Engineering at the University of Florida, Gainesville from 1970-1980, and then joined the MIT Department of Electrical Engineering and Computer Science faculty in 1980. He works in the ... En savoir plus
