Effect of die metallization layer ageing in the case of power semiconductor devices

The paper describes ageing mechanisms of the metallization layer deposited on the chips of power semiconductor devices, and the effects of its ageing on the electrical characteristics of a COOLMOSTM Transistor. We have tried to link the changes in…

Une méthode de réduction exacte pour la segmentation par graph cuts

From now on, graph cuts are a standard in the computer vision community. However, their huge memory consumption remains a challenging problem since underlying graphs contains billions of nodes and even more edges. Except some exact methods [14, 10,…

Object Tracking based on Particle Filtering with Multiple Appearance Models

In this paper, we propose a novel method to track an object whose appearance is evolving in time. The tracking procedure is performed by a particle filter algorithm in which all possible appearance models are explicitly considered using a mixture…

Design and realization of a microfluidic device devoted to the application of ultra-short pulses of electrical field to living cells

In this paper, we present a novel microfluidic system dedicated to the application of ultra short pulses (i.e. nanopulses) on cells and the visualization of their effects. Cell plasma membranes can be rendered permeable by the use of nanosecond…
