Improvement of HepG2/C3a cell functions in a microfluidic biochip.

Current developments in tissue engineering and microtechnology fields allow the use of microfluidic biochip as microtools for in vitro investigations. In the present study, we describe the behavior of HepG2/C3a cells cultivated in a poly…

High insulation Power supply for high-power IGBT gate drivers in a multilevel converter

Actually in ALSTOM’s locomotives, the power train is supplied by a heavy 25kV/3kV transformer. To reduce the weigh and volume of the system, a multilevel converter directly linked to the catenary, is intended to be developed. So, each component of…

Insulated gold micro singularities for high density cell trapping based on dielectrophoresis

Dielectrophoresis (DEP) is broadly used in microfluidic systems for the cell therapies or medical diagnostics [1] because of its capability to handle and sort biological cells [2,3]. In this paper, a new method to trap cells on-chip with high…

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…
