PIV measurements in a turbulent wall jet over a backward-facing step in a three-dimensional, non-confined channel

Thien Duy Nguyen, Souad Harmand

A study of a turbulent wall jet over a backward-facing step is especially of interest because it shows a rich phenomenon flow and a mechanism to alter the flow characteristics downstream of the step. However, studies on this flow configuration are rare. In this paper, we considered this flow...

Multiscale finite element modelling of ductile damage behaviour of the human femur under dynamic loading

Hakim Naceur, Jamila Rahmoun, Julien Halgrin, Patrick Chabrand

In this paper, we propose a new multiscale finite element methodology based on a recently developed micromechanical damage model for the modelling of the human bone behaviour under dynamic loading. The damage is carried out by the framework of the limit analysis based on the MCK (Monchiet,...

Study of fatigue failure in Al-chip-metallization during power cycling

Camille Durand, Markus Klingler, Daniel Coutellier, Hakim Naceur

This paper studies the failure mechanisms occurring in the chip-metallization of a new power module using a copper clip soldered on the top side of the chip, instead of aluminum wire bonds. Both power cycling tests and thermo-mechanical Finite Elements simulations are performed. Simulations of...

Anti-windup based dynamic output feedback controller design with performance consideration for constrained Takagi–Sugeno systems

Tran Anh-Tu Nguyen, Antoine Dequidt, Michel Dambrine

This paper proposes an LMI-based method to guarantee the closed-loop regional stability and performance for Takagi-Sugeno systems that are subject to input saturation, state constraints and also amplitude-bounded disturbance. Based on Lyapunov stability tool, the proposed method provides conditions...

Message forwarding based on vehicle trajectory history in Fully Distributed Traffic Information Systems

Alain Gibaud, Philippe Thomin

Fully Distributed Traffic Information Systems (fdtis) are based on vehicle-to-vehicle wireless data transmission that enables traffic self-organization. For instance, alert messages transmitted by vehicles in poor traffic conditions allow receivers to avoid congested roads and reduce travel time....

Étude de stratégies de groupement au sein d’un cross dock de l’Internet Physique

Yves Sallez, Thierry Berger, Thérèse Bonte, Damien Trentesaux

L’Internet Physique est basé sur l’encapsulation du fret via l’adoption de containers standardisés (nommés PI-containers) et l’usage de protocoles standards pour le routage de containers, entre les acteurs de la logistique. Pour que l’approche Internet Physique devienne une réalité, une gestion...

Etude numérique et expérimentale d'un modèle de balayage dans un moteur 2-temps à allumage spontané

Stéphanie Cagin, Nachida Bourabaa, Xavier Fischer, Eric Delacourt, Céline Morin, Daniel Coutellier, Bertrand Carre, Sylvain Loumé

Cet article présente une modélisation numérique 3D de l’aérodynamique interne d’un moteur 2 temps durant la phase de balayage. Cette modélisation est ensuite confrontée à des essais en soufflerie grâce à une maquette à l’échelle 1 du cylindre moteur pour 2 positions du piston et plusieurs...

Spectroscopic studies of carbon monoxide: application for detection in flames

Olivier Carrivain, Mikael Orain, Nelly Dorval, Céline Morin, Guillaume Legros

In this study, we investigated both experimentally and numerically two-photon laser-induced fluorescence from carbon monoxide (CO-TPLIF) in order to determine the applicability of this technique for imaging CO concentration in aircraft combustion chamber. Experiments were carried out in an optical...

Recherche d'information dirigée par les interfaces utilisateur : approche basée sur l'utilisation des ontologies de domaine, User interface-driven information retrieval : an ontology-based approach

Amir Zidi

Ce mémoire porte sur l'utilisation des ontologies dans les systèmes de recherche d'information SRI dédiés à des domaines particuliers. Il se base sur une approche à deux niveaux, à savoir la formulation et la recommandation des requêtes. La formulation consiste à assister l'..., This thesis study the using of ontologies in information retrieval systemdedicated to a specific domain. For that we propose a two-level approach to deal with i) the query formulation that assists the user in selecting concepts and properties of the used ontology ; ii) the query recommendation that...
