Sur l'utilisation active de la diversité dans la construction d'ensembles de classifieurs. Application à la détection de fumées nocives sur site industriel, On the usability of diversity when training multiple classifier systems. Application to the detection of hazardous smokes on industrial facilities.

David Gacquer

L'influence de la diversité lors de la construction d'ensembles de classifieurs a soulevé de nombreuses discussions au sein de la communauté de l'Apprentissage Automatique ces dernières années. Une manière particulière de construire un ensemble de classifieurs consiste à sélectionner…, Discussions about the influence of diversity when designing Multiple Classifier Systems has been an active topic in Machine Learning overs recent years. One possible way of considering the design of Multiple Classifier Systems is to select the ensemble members from a large pool of classifiers…

WISDOM : Méthode d'aide à la conception de sites web basée sur la réutilisation conceptuelle et logicielle, WISDOM : a web site design method based on the reuse of design & software solutions

Etienne Cocquebert

La nature et les acteurs d'un site web ont considérablement évolués depuis leur apparition en 1996 : les premiers sites diffusaient de l'information statique et étaient réalisés de manière artisanale par peu d'acteurs, alors que désormais, ils sont devenus un vecteur privilégié d…, The nature and actors of a website have evolved since their emergence in 1996: the first sites displayed static information and were achieved by few designers, whereas they become the usual way to broadcast dynamic information, to collaborate between users and are made by team projects involving…

A behavioral multi-agent model for road traffic simulation

Arnaud Doniec, René Mandiau, Sylvain Piechowiak, Stéphane Espié

Multi-agent systems allow the simulation of complex phenomena that cannot easily be described analytically. Multi-agent approaches are often based on coordinating agents whose actions and interactions are related to the emergence of the phenomenon to be simulated. In this article, we focus on road…

An alternative to inverse dynamics joint torques estimation in human stance based on a Takagi-Sugeno unknown inputs observer in the descriptor form

Kevin Guelton, Sebastien Delprat, Thierry-Marie Guerra

An alternative to inverse dynamics joint torques estimation in human stance is proposed. This alternative is based on unknown-input observers which allow real-time estimation of joint torques and angular velocities from measurements of the angular positions. To design the aforementioned observer, a…

Propulsion and Braking in the Study of Asymmetry in Able-Bodied Men's Gaits

François Potdevin, Christophe Gillet, Franck Barbier, Yann Coello, Pierre Moretto

The present study was designed to test functional differences between both lower limbs in able-bodied gait according to fore-aft force impulse analyses and to assess the existence of a preferential lower limb for forward propulsion and braking. The leg that did more of the braking (Most Braking…

Does B.I.R.D foot control supply sensitivity disturbance induced by EMLA cream anaesthesia ?

Aurélien Descatoire, Pierre Moretto

Numerous studies on the development of new biofeedback device conception have already been undertaken. Patients with loss of protective pain sensation are unable to modify their gait when abnormal and excessive plantar pressure occurs. For this reason, _we have developed and tested a portable…

Turbocharged SI engine modelling and control strategy

Djamel Khiar, Jimmy Lauber, Thierry-Marie Guerra, Thierry Floquet, Guillaume Colin, Yann Chamaillard

This paper deals with the non-linear modelling and control of a turbocharged spark ignition engine. In the automotive industry, downsizing-based turbocharging is considered as a powerful technique to improve engine performances as fuel economy, pumping loss reduction to increase engine efficiency…

Eléments finis hybride déplacement perforés pour le calcul des structures aéronautiques rivetées

Nicolas Leconte

Dans le cadre de l'étude par éléments finis de structures aéronautiques soumises à l'impact, la prédiction des modes de ruine engendrés au sein ou au voisinage des assemblages rivetés, telle que la déchirure d'une tôle le long d'une ligne de rivets, s'avère, encore aujourd…, The prediction of rupture initiation and propagation in full-scale aeronautic structures subjected to impact is still nowadays troublesome. One main problem concerns the difference between the scale of the aeronautic structure and the one of the riveted assembly. Indeed, it seems that the modelling…

Optimisation des performances et de la consommation de puissance électrique pour architecture Intel ltanium/EPIC, Performance and Energy Optimization for Intel Itanium/EPIC architecture for Virtual Machine Support

Jamel Tayeb

Cette thèse propose, dans sa première partie, d’étendre l’architecture EPIC des processeurs de la famille Itanium par l’ajout d’une pile matérielle. L’idée principale est qu’il est possible de combler l’écart de performance entre une architecture généraliste et les circuits spécialisés pour…, This thesis proposes, in its first part, to extend the EPIC architecture of the Itanium processor family by providing a hardware stack. The principal idea defended here is that it is possible to close the existing performance gap between generic architectures and application specific designs to run…

Robust pole placement controller design in LMI region for uncertain and disturbed switched systems

Badr Mansouri, Noureddine Manamanni, Kevin Guelton, Mohamed Djemai

This paper concerns the state feedback control for continuous-time, disturbed and uncertain linear switched systems with arbitrary switching rules. The main result of this work consists in getting a LMI (Linear Matrix Inequalities) condition guaranteeing a robust pole placement according to some…
