Reproducing topography and roughness of osteoconductive materials in a microfluidic device for bone tissue engineering

This paper is in the framework of tissue engineering, based on bioreactor for cultivating bone-forming cells on biomimetic materials, such as coral scaffold. In order to optimize such process and to have a better understanding of biophysical and…

Energy Recovery Power Supply for Piezoelectric Actuator

Piezoelectric actuators are used successfully to enable locomotion of micro-robot such as micro air vehicle with flapping wings. However, the use of piezoelectric actuators presents a major challenge for power electronic design: the input…

Extended braking stiffness estimation based on a switched observer, with an application to wheel-acceleration control

In the context of hybrid anti-lock brake systems (ABS), a closed-loop wheel-acceleration controller based on the observation of the extended braking stiffness (XBS) is provided. Its objective is to improve the system's robustness with respect to…

Context-based vector fields for multi-object tracking in application to road traffic

In this contribution, we propose to use road and lane information as contextual cues in order to increase the precision of multi-object object tracking. For tracking, we employ a Monte Carlo implementation of a Probability Hypothesis Density (PHD)…

SuperFAST: Model-Based Adaptive Corner Detection for Scalable Robotic Vision

— In this study, we propose a novel solution to regulate the amount of interest points extracted from an image without significant additional computational cost. Our method acts at the very beginning of the detection process by using a corner…

Low Computational-cost determination of Vibrational Behavior: Application to Five-phase Flux-Switching Permanent-Magnet Motor

This paper presents a study of the vibrational behavior of a five-phase flux-switching permanent-magnet (FSPM) motor with a low computational-cost. Magnetic and mechanical models are sequentially considered to predict the acoustic noise generated by…

Étude du comportement thermique d'un composant GaN de puissance

Nous nous intéressons dans cet article au comportement thermique des transistors GaN du puissance fabriqués par EPC (eGaN FET) afin de pouvoir estimer précisément leurs pertes par commutation. Après avoir présenté l'évolution des caractéristiques…
