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…

Experimental study of nitrogen flow rate effect on olives pomaces wastes pyrolysis using thermogravimetric analysis

Emna Berrich, Mansoura Salhi, Mehrez Romdhane, Fethi Aloui

Olives pomaces wastes (OPW) pyrolysis behaviour was studied using thermogravimetric analysis under inert conditions. Nitrogen flow effect on OPW thermal degradation was illustrated and discussed. Thermal residence time, peaks numbers, the maximum temperatures and the conversion rates were…

Designing human–system cooperation in industry 4.0 with cognitive work analysis: a first evaluation

Marie-Pierre Pacaux-Lemoine, Quentin Berdal, Clément Guerin, Philippe Rauffet, Christine Chauvin, Damien Trentesaux

One objective of Industry 4.0 is to reach a better system performance as well as to have a better consideration of humans. This would be done by benefiting from knowledge and experience of humans, and balancing in a reactive way some complex or complicated tasks with intelligent systems. Several…

Distributed time-varying formation tracking of multi-quadrotor systems with partial aperiodic sampled data

Syed Ali Ajwad, Emmanuel Moulay, Michael Defoort, Tomas Menard, P. Coirault

In this article, a distributed formation tracking controller is proposed for Multi-Agent Systems (MAS) consisting of quadrotors. It is considered that each quadrotor in the MAS only shares its translation position information with its neighbors. Moreover, position information is transmitted at…

Adaptive Backstepping Integral Sliding Mode Control Combined with Super-Twisting Algorithm For Nonlinear UAV Quadrotor System

Yakoub Nettari, Moussa Labbadi, Serkan Kurt

Quadrotors are extremely agile UAVs with many uncertainties related to their moment of inertia, drag coefficients, and mass. Besides aerodynamic turbulence, the quadrotor is rich in non-linearity due to its underactuated mechanical system. These last two factors lead to problems that require…

Robust flight control for a quadrotor under external disturbances based on generic second order sliding mode control

Abdellah Benaddy, Moussa Labbadi, Mostafa Bouzi

This paper presents a novel robust second order sliding mode control (RSOSMC) for tracking controller of a quadrotor with external disturbances. In addition, in order to perform the position and attitude tracking control of the quadrotor perfectly, the dynamical model of the quadrotor is divided…

Obstacle avoidance in highly automated cars: can progressive haptic shared control make it safer and smoother?

Béatrice Pano, Philippe Chevrel, Fabien Claveau, Chouki Sentouh, Franck Mars

Haptic shared control has proven to be an effective method to assist a driver in controlling a vehicle. This method is now being considered for use in developing strategies for smooth transitions between manual and autonomous driving modes. This paper has two objectives. First, it proposes to adapt…

Two-Step Validation of a New Wireless Inertial Sensor System: Application in the Squat Motion

Mathias Blandeau, Romain Guichard, Rémy Hubaut, Sébastien Leteneur

The use of Inertial Measurement Units (IMUs) can provide embedded motion data to improve clinical application. The objective of this study was to validate a newly designed IMU system. The validation is provided through two main methods, a classical sensor validation achieved on a six-degrees-of-…

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…
