Over-wavelength pitch sized diffraction gratings for augmented reality applications

Valter Drazic, Oksana Shramkova, Bobin Varghese, Laurent Blondé, Vincent Brac de La Perrière, Jesse Schiffler, Patrice Twardowski, Sylvain Lecler, Benjamin Walter, Estelle Mairiaux, Fuanki Bavedila, Marc Faucher, Valérie Allié

Waveguide based optical combiners for augmented reality (AR) glasses are integrating several surface relief gratings (SRG) whose pitch sizes can be as small as 200 nm for the blue wavelength. All SRG components exploit the first diffraction order to couple in and out or to deviate the light. We...

Fault Detection and Isolation in Connected Multi-Robot Systems, Détection et isolation des défauts dans les systèmes multi-robots contrôlés

Anass Taoufik

Multi-Agent Systems (MASs) have attracted much popularity, since the previous decade due to their potential wide range of applications. Indeed, connected MASs are deployed in order to achieve more complex objectives that could otherwise not be achievable by a single agent. In distributed schemes,..., Les systèmes multi-agents (SMAs) ont beaucoup attiré depuis la décennie précédente en raison de leur large éventail d’applications. En effet, les SMAs connectés sont déployés afin d’atteindre un objectif plus complexe qui pourrait autrement ne pas être réalisable par un seul agent. Dans les...

Deep Gaussian Process for the Approximation of a Quadratic Eigenvalue Problem: Application to Friction-Induced Vibration

Jeremy Sadet, Franck Massa, Thierry Tison, El-Ghazali Talbi, Isabelle Turpin

Despite numerous works over the past two decades, friction-induced vibrations, especially braking noises, are a major issue for transportation manufacturers as well as for the scientific community. To study these fugitive phenomena, the engineers need numerical methods to efficiently predict the...
