This study examines the evolution of the functional properties of two hemp concretes formulated with two different binders over 2 years in different environmental conditions. Stable environmental conditions (50% RH - 20°C) have been applied to hemp concretes to obtain the reference aging AREF. An accelerated aging process AWD is chosen, consisting ...
Proton exchange membrane fuel cells are promising energy conversion solutions for both stationary and transportation applications. However, for the latter application, durability still needs to be improved in order to compete with internal combustion engine. Therefore, many researches have been carried out to improve their design, materials, reliab...

Ce travail de synthèse présente un recueil des travaux que j'ai effectués depuis les années 1990 et qui s';inscrit au carrefour des domaines de la psychologie cognitive du handicap, de la neuropsychologie et de la psycho-ergonomie. Il est centré sur la notion d'adaptation. Cette notion est très ancienne, elle remonte à la théorie de l'évolution mai...
Electro-mobility is increasing significantly in the urban public transport and continues to face important challenges. Electric bus fleets require high performance and extended longevity of lithium-ion battery at highly variable temperature and in different operating conditions. On the other hand, bus operators are more concerned about reducing ope...
Contexte : Selon l'Organisation Mondiale de la Santé, le nombre de personnes de plus de 60 ans devrait doubler d'ici 2050, représentant 22% de la population mondiale (« OMS | Vieillissement et santé », 2018). Le vieillissement de la population et de l'allongement de l'espérance de vie représente un enjeu majeur en termes de santé et de mobilité. Ce...

This article aims to understand better the mechanical properties and behavior of organic matrix composite materials under elevated temperature conditions. Two specific specimens of cured RTM6 epoxy resin are tested with DMA analysis: one being unaged and the other one aged for 5000 h at 130 °C under ambient air. Anti-plasticization effects seem to ...
Les scénarios de rupture des digues sont basés sur des hypothèses d'enchaînement de dégradations ou de ruptures partielles de différentes parties des ouvrages. Ainsi, pour qu'une défaillance intervienne sur un tronçon de digue, il faut que certaines parties d'ouvrage arrivent à la limite de leur 'bon' fonctionnement et que leurs propriétés passent ...
