The recent advances made in MEMS and particularly in RF MEMS technology are enabling new architectures for the integration of RF transceivers with improved performance and smaller size. Several fundamental building blocks benefit from the availability of h ...
This paper presents the modeling, detailed simulation, and test of an efficient medium-voltage adjustable-speed drive. The system consists of a three-level neutral-point-clamped inverter supplied by a 12-pulse rectifier. To achieve a motor-friendly supply, ...
Recent experimental progress in cavity optomechanics has allowed cooling of mesoscopic mechanical oscillators via dynamic backaction provided by the parametric coupling to either an optical or an electrical resonator. Here we analyze the occurrence of norm ...
The aim of this paper is to present a universal power quality conditioning system (UPQS) named after unified power quality conditioner, which is extended by adding a shunt active filter at the load side. Its main purpose is to compensate for both supply vo ...
Diffraction gratings integrated with micro-electro-mechanical-systems (MEMS) offer shot noise limited subnanometer displacement detection sensitivities but are limited in detection range for mechanical transducers. A two-wavelength readout method is develo ...

Wireless communication systems and handset devices are showing a rapid growth in consumer and military applications. Applications using wireless communication standards such as personal connectivity devices (Bluetooth), mobile systems (GSM, UMTS, WCDMA) an ...
The miniaturization of classical electromagnetic transformers raises certain problems such as manufacture both the coils and the magnetic core, increase in magnetic leak and especially electromagnetic pollution of the environment. One interesting solution ...

In the nanocomposite bone, inorganic material is combined with several types of organic molecules, and these complexes have been proposed to increase the bone strength. Here we report on a mechanism of how one of these components, human osteopontin, forms ...
Traffic loads combined with moisture variations are the most harmful for road structures. Even if the pavement is assumed to have an elastic behaviour, the partially saturated subsoil can present irreversible strains that endanger the integrity of the road ...
NMR-microprobes based on solenoids and Helmholtz coils have been microfabricated and NMR-spectra of mammalian cells have successfully been taken. The microfabrication technology developed for these probes consists of three electroplated copper levels for l ...
