Relation usinabilité-topographie de la surface usinée. Analyse conventionnelle et par la théorie du chaos

Maxence Bigerelle, Jérome Gavois, Alain Iost

Cet article propose d'analyser l'usinabilité en tournage d'un acier martensitique en fonction de la vitesse de coupe par observation topographique de la surface. Nous décrivons d'abord une méthodologie pour chercher le paramètre de rugosité le plus pertinent afin de caractériser…

Evaluation of agent-based interactive systems : proposal of an electronic informer using Petri Nets

Chi Dung Tran, Houcine Ezzedine, Christophe Kolski

The evaluation of interactive systems has been an active subject of research for many years. Many methods and tools have been proposed but most of them do not take architectural specificities of agent-based interactive systems into account. In addition, electronic informers are popular evaluation…

Real time control of hybrid electric vehicle on a prescribed road

Saida Kermani, Sebastien Delprat, Thierry-Marie Guerra, Rochdi Trigui

Hybrid vehicles use two energy sources for their propelling. In order to investigate an optimal splitting of the power flows between the engine and the electric machine, an optimal control algorithm is recalled. A new formulation using maps allows a very fast solving this problem which then may be…

Predictive energy management of hybrid vehicle

Saida Kermani, Sebastien Delprat, Rochdi Trigui, Thierry-Marie Guerra

Hybrid vehicles use two energy sources for their propelling. Usually an Internal Combustion Engine (ICE) is used with one or more electric machine(s) (EM). The problem is then to split the driver power demand between the ICE and the EM in order to minimize a criterion, usually the fuel consumption…

Vers une modélisation des systèmes coopératifs

Serge Debernard, David Annebicque, Igor Crevits, Thierry Poulain

Dans le cadre de la coopération homme-homme, les agents humains construisent et maintiennent une représentation partagée de la situation par l'intermédiaire d'échanges verbaux. Cette représentation a été appelée Référentiel Commun, mais n'est que virtuelle. Dans le cadre de la…

Joint design and pricing on a network

Luce Brotcorne, Martine Labbé, Patrice Marcotte, Gilles Savard

To optimize revenue, service firms must integrate within their pricing policies the rational reaction of customers to their price schedules. In the airline or telecommunication industry, this process is all the more complex due to interactions resulting from the structure of the supply network. In…

Data aggregation in VANETs : the VESPA approach

Bruno Defude, Thierry Delot, Sergio Illari, Jose Luis Zechinelli Martini, Nicolas Cenerario

VESPA (Vehicular Event Sharing with a mobile P2P Architecture) is a system designed for vehicles to share information in vehicular ad-hoc networks (VANETs). The originality of VESPA is to support any type of event (e.g., available parking spaces, accidents, emergency braking, information relative…
