The paper deals with the modeling and analysis of low voltage (LV) power distribution networks feeding residential, commercial and small industrial consumers including distributed generation units and storage systems. It focuses on an optimization model for the energy management system of the experimental microgrid built at the University of Applied Sciences and Arts of Western Switzerland, HES-SO...
The overlapping time of double-contact circuit breakers is defined as the time delay elapsing between the opening of the nominal and the arcing contact pairs. It is an important criteria for the circuit breaker lifetime. It is usually determined indirectly on live breakers, e.g. derived from the number of switching operations and interrupted current amplitudes, or directly during the breaker overhaul,...

In this paper, we exemplify the power reduction that can be achieved by using analogue rather than digital signal processing. This reduction is illustrated with an FSK demodulation. The power reduction is achieved using conventional off-the-shelf discrete electronics components rather than through an ASIC implementation. The power consumption is reduced by a factor of more than ten; more specifically,...
Replica detection is a prerequisite for the discovery of copyright infringement and detection of illicit content. For this purpose, content-based systems can be an efficient alternative to watermarking. Rather than imperceptibly embedding a signal, content-based systems rely-on image similarity. Certain content-based systems use adaptive classifiers to detect replicas. In such systems, a suspect image...
