Effect of moisture uptake on flax-reinforced composite laminates: influence on dynamic and quasi-static properties
2016
International audience; This study proposes to investigate the effect of moisture uptake on a wide spectrum of mechanical behaviours of unidirectional flax fibre-reinforced epoxy laminates. It includes tensile monotonic and fatigue testing. Results show that UD flax-epoxy composites, whenexposed to hygrothermal conditioning at 70°C and 85% RH, exhibit a diffusion kinetic which follows a one dimensional Fickian behaviour. The mass uptake at equilibrium is approximately 3.3 % and the diffusion coefficient 6.5 10-6 m2.s-1. Water vapour sorption is shown to induce a significant change in the shape of the tensile stress-strain curve. Contrary to all expectations, water saturation does not degrad…

Fast Optimization Scheme for the Muscular Response to FES Stimulation to Design a Smart Electrostimulator
2022
In this article, we present the design of a smart electrostimulator for muscle rehabilitation or reinforcement, using fast computations, in order to control the muscular force. The Ding and al. model allows to predict and to optimize the muscular force response to functional electrical stimulation. [1]. We analyze the estimation of the Ding and al. parameters using an approximation of the force response [6] which depends upon the 6 parameters of the Ding's model and we derive optimization scheme which bypass the time computational expensive integration of the dynamics of the Ding and al. equations.
Prédiction de cycle et stratégie de gestion énergétique basée sur une méthode d’optimisation globale
2017
International audience; La nécessité de prédire le cycle de conduite d’un automobiliste afin d’améliorer sa gestion énergétique et ainsi réduire la consommation de carburant a été démontré (Debert, Quigley). Dès lors, il serait aisé d’appliquer une méthode d’optimisation globale, telle que la Programmation Dynamique (DP en anglais), pour obtenir la stratégie optimale. Cette méthode est déjà utilisée dans de nombreuses applications (Sciarretta), mais au quotidien nombreux sont les facteurs environnants qui peuvent perturber les conditions de circulation (météo, travaux, accidents....) et impacter le cycle de conduite. Il est donc nécessaire d’élaborer une stratégie adaptative en temps réel. …
A multi-agent based cooperative control model applied to the management of vehicles-trains
2017
The use of individual vehicles is becoming more and more important in inner cities, leading to many side problems such as traffic jam, air pollution and accidents. Intelligent vehicles have been studied so as to overcome these problems. Some solutions provided by these works are already available to the general public market such as city safety systems, lane assists,... Many research works are focusing on finding suitable and acceptable solutions to these problems and dealing with traffic jam management. The proposal can tackle the traffic jam problem whether on system level or on individual vehicle providing better control and perception systems aimed at reducing time response and/or at in…
