Building, sharing and exploiting spatio- temporal aggregates in vehicular networks

Dorsaf Zekri, Bruno Defude, Thierry Delot

This article focuses on data aggregation in vehicular ad hoc networks (VANETs). In such networks, data produced by sensors or crowdsourcers are exchanged between vehicles in order to warn or inform drivers when an event occurs (e.g., an accident, a traffic congestion, a parking space released, a…

Folk-IS : Opportunistic Data Services in Least Developed Countries

Nicolas Anciaux, Luc Bouganim, Thierry Delot, Sergio Ilarri, Leila Kloul, Nathalie Mitton, Philippe Pucheral

According to a wide range of studies, IT should become a key facilitator in establishing primary education, reducing mortality and supporting commercial initiatives in Least Developed Countries (LDCs). The main barrier to the development of IT services in these regions is not only the lack of…

Optimized Hybrids

Sebastien Delprat, Christian Fontaine, Sebastien Paganelli

Today, hybrids are on the road, from affordable micro hybrids providing mostly the stop&start feature, up to more expensive systems with signifi - cant pure electric mode range. One of the challenges is to improve the control algorithms to reach better fuel economy and reduce emissions.…

Identification of heat partition in grinding related to process parameters, using the inverse heat flux conduction model

Eduardo García, Damien Méresse, Iñigo Pombo, Souad Harmand, José Antonio Sánchez

Grinding is an abrasive machining process characterized by producing high quality components for high added-value industries. Thermal damage is an undesired phenomenon that may ruin nearly finished products. The study of thermal damage requires understanding the mechanisms of heat partition between…

Representation of the Agent Environment for Traffic Behavioral Simulation.

Feirouz Ksontini, Stéphane Espié, Zahia Guessoum, René Mandiau

The aim of this paper is to improve the validity of traffic simulations in (sub-)urban context, with a better consideration of driver behavior in terms of anticipation of positioning on the lanes and occupation of space. We introduce a model based on a multi-agent approach and the emergence concept…

Fracture mechanics in new designed power module under thermo‐mechanical loads

Camille Durand, Markus Klingler, Daniel Coutellier, Hakim Naceur, Arian Grams, Olaf Wittler

Thermo-mechanically induced failure is a major reliability issue in the microelectronic industry. On this account, a new type of Assembly Interconnected Technology used to connect MOSFETs in power modules has been developed. The reliability is increased by using a copper clip soldered on the top…
