The invention relates to a device comprising a conductive surface (12) and electrical contacts (14) by which an electric current is able to be passed. Said electrical contacts (14) comprise conductive seeds (16) deposited on the conductive surface (12), an ...
This paper presents a general analytical model for predicting the magnetic field of slotless permanent-magnet machines. The model takes into account the effect of eddy currents in conductive regions and notably in conductive permanent magnets without negle ...
This paper presents a microelectronic emulation approach for high-speed power system computation. First, the problems of existing power system simulators are detailed. This shows that microelectronic emulation is a possible solution for solving the speed p ...
This paper joins a series of papers dealing with high-speed power system emulators. It clarifies the last details about the system level of the AC emulation approach by analyzing and quantifying the systematic errors introduced during modeling. Thereby a n ...
This paper introduces a special mx3 matrix converter connected between the stator of a poly-phased synchronous generator and a power grid. Some commutations of the chosen switching scheme induce voltage surges due to leakage inductances of the generator. T ...

Faraday rotation is a fundamental magneto-optical phenomenon used in various optical control and magnetic field sensing techniques. Recently, it was shown that a giant Faraday rotation can be achieved in the low-THz regime by a single monoatomic graphene l ...
Nowadays many consumer electronic devices are using small engines (micromotors). Thanks to technological innovation, the components can be imbedded into numerous portable systems. The key factors for a nomadic integration are: reduction of power consumptio ...
A novel charge pulse detection circuit is presented, consisting of a continuous reset resistor in series with the charge pulse generator, followed by a simple amplifier and pulse shaping circuit. Realization with a 0.18 μm CMOS process (UMC) will result in ...
Asymmetric cell division is an evolutionarily conserved process that gives rise to daughter cells with different fates. In one-cell stage C. elegans embryos, this process is accompanied by asymmetric spindle positioning, which is regulated by anterior-post ...
The present invention concerns a permeable-magnetocaloric material for a magnetic refrigerator, a heat pump or a power generator comprising at least a magnet assembly for the generation of a magnetic field, a body disposed at least partially in said magnet ...
