Influence de la rugosité de surfaces de parois sur les instabilités hydrodynamiques d'un écoulement de Couette-Taylor et de Couette-Taylor-Poiseuille, Influence of surface irregularities on hydrodynamic instabilities in Couette-Taylor and Couette-Taylor-Poiseuille flow

Lamia Gaied

Ce travail porte sur l’étude numérique et expérimentale d’un écoulement de Couette-Taylor dans une géométrie à surfaces rugueuses, afin de détecter l’effet de la rugosité sur les instabilités hydrodynamiques. Dans un premier temps, nous avons effectué une étude de simulation numérique (CFD) 3D dans…, : This work deals with a numerical and experimental study of the Couette-Taylor flow where the geometry contains rough surfaces, in order to detect the effect of these irregularities on the hydrodynamic instabilities. Firstly, we carried out a 3D mumerical simulation study (CFD) in the case of a…

Minimising the User’s Effort during Wheelchair Propulsion using an Optimal Control Problem

Ouazna Oukacha, Chouki Sentouh, Philippe Pudlo

This paper proposes a study of the optimal control problem with state constraint, using two types of a power-assist wheelchair propulsion. The cost function is given by the metabolic function, which represented by acompromise between the work exerted by the joints muscles (mechanical effect) and an…

Effect of sensory stimulation applied under the great toe on postural ability in patients with fibromyalgia

Frédéric Viseux, Daniel Martins, Philippe Villeneuve, Pascal Charpentier, Leandra de Sant’anna E Silva, Afonso Salgado, Antoine Lemaire

Fibromyalgia (FM) is a chronic pain syndrome, characterised by several symptoms. One of the most prevalent symptoms in FM is balance impairment that compromise the autonomy, function and performance status of patients. Purpose: The main objective of the present study was to evaluate the effect of…

Toward real-time road detection for autonomous vehicles.

Yazid Lachachi, Mohamed Ouslim, Smail Niar, Abdelmalik Taleb-Ahmed

Road detection is a vital task for autonomous vehicles, as it has a direct link to passengers’ safety. Given its importance, researchers aimed to improve its accuracy and robustness. We look at the task from a holistic point of view, where we aim to balance computation and accuracy. A multimodal…

Privacy stochastic games in distributed constraint reasoning.

Julien Savaux, Julien Vion, Sylvain Piechowiak, René Mandiau, Toshihiro Matsui, Katsutoshi Hirayama, Makoto Yokoo, Shakre Elmane, Marius Silaghi

In this work, we approach the issue of privacy in distributed constraint reasoning by studying how agents compromise solution quality for preserving privacy, using utility and game theory. We propose a utilitarian definition of privacy in the context of distributed constraint reasoning, detail its…

Exponential stability criteria for neural network based control of nonlinear systems

Ayush Kumar Jain, Christophe Fiter, Denis Berdjag, Philippe Polet

This paper investigates the problem of exponential stability of neural network controlled sampled-data systems. The stability of the closed loop system is formulated using Lyapunov-Krasovskii approach. Using a time-dependent Lyapunov function, novel conditions are proposed to guarantee the…

A non-triangular hub location problem

Jack Brimberg, Nenad Mladenovic, Raca Todosijević, Dragan Urošević

Hub location problems generally assume that the triangle inequality applies on the edges of a complete graph. Hence the flow between any pair of nodes requires at most two hubs for the transfer process. Here we relax the triangle inequality restriction and present two new formulations of the…
