Roughness multiscale analysis of wear mechanisms in polymer abrasion

Robin Guibert, Julie Lemesle, Frédéric Robache, Maxence Bigerelle

Polymers are essential for the automotive industry, the aircraft industry and medical devices due to their combination of lightness and strength. However, performance of polymers might decrease with their degradation and wear studies become necessary to ensure both usefulness and safety during…

Drivers' behavior modeling in a traffic surrounding an autonomous vehicle, Modélisation du comportement des conducteurs dans un trafic environnant un véhicule autonome

Daniel Cisneros Lombera

The validation of autonomous vehicles is a complex task, because to cover all the possible and potential cases that need to be validated, it will require drives of several tens of millions of kilometers, as required by the regulations. This is very costly, but also, and above all, will require…, La validation des véhicules autonomes est une tâche complexe, car pour couvrir tous les cas possibles et potentiels qui doivent être validés, cela demandera des roulages de centaines de millions de kilomètres, comme l'exige la réglementation. Ce qui est très coûteux, mais aussi, et surtout,…
