Skin surface nanoscale topography by light interferometry

The skin is the first thing one perceives of a person. Unconsciously, its color, its radiance and its complexion give us a first impression of a person. This is why cosmetic care and makeup products are of great importance. But how to evaluate their…

Dispersion of electrical characteristics and short-circuit robustness of 600V E-mode GaN transistors

This paper presents an experimental study of the robustness of 600 V normally-off GaN High Electron Mobility Transistors (HEMT) submitted to Short-Circuits (SC) operations. The obtained results reveal a severe dispersal in terms of SC robustness:…

A Numerical Approach for the Mechanical Analysis of Superconducting Rutherford-Type Cables Using Bimetallic Description

Low-temperature superconductors are widely used in high-field magnets, mostly within Rutherford-type cables. The run for higher fields leads to greater forces on the conductor, which is pushed closer to its mechanical limit. Managing the higher…

Impact of thermal stress on the ageing behaviour of aluminum electrolytic capacitors for automotive applications

DC link filter capacitors used in electric drives for automotive applications are most of the time aluminum electrolytic capacitors. However their high sensitivity to temperature results in very weak components. So, a lot of studies have been made…

Robust Calibration of Radio Interferometers in Non-Gaussian Environment

The development of new phased array systems in radio astronomy, as the low frequency array (LOFAR) and the square kilometre array (SKA), formed of a large number of small and flexible elementary antennas, has led to significant challenges. Among…
