Stitching of 3D Elementary Topographies for Roughness Multiscale Analysis: Development, Optimization and Applications, Stitching de Topographies 3D Elémentaires pour l'Analyse Multi-Echelle de Rugosité : Développement, Optimisation et Applications

Robin Guibert

Surface roughness is linked to numerous physical phenomena, involved both in manufacturing (friction, visual aspect ...) and in day-to-day life (walking, object gripping ...). Roughness multiscale analysis is notably a powerful tool allowing the isolation of physical phenomena by their scale of…, La rugosité de surface est liée à de nombreux phénomènes physiques, ayant des implications tant d’un point de vue industriel (frottement, aspect visuel ...) que quotidien (marche, préhension des objets ...). L’analyse multiéchelle de la rugosité est notamment un puissant outil permettant l’…

Thèse

Détermination biomécanique d’indicateurs de dégradation précoce de la locomotion chez des patients présentant une Sclérose en Plaques, Determination of biomechanical markers characterizing early deterioration of locomotion in patients with Multiple Sclerosis

Caroline Massot

En dépit des plaintes des patients, la prise en charge rééducative de la Sclérose en Plaques (SEP) précoce se heurte à la difficulté d’objectiver les troubles locomoteurs par les tests cliniques. L’objectif général de ce travail de thèse était d’apporter une réponse à ce verrou clinique en…, Despite patients complaints, the rehabilitation of people with Multiple Sclerosis (MS) at an early stage of the disease is challenging due to the difficulty of describing locomotor disorders through clinical tests. The general objective of this thesis work was to provide an answer to this clinical…

A global approach to fault detection in multi-agent systems with switching topologies subject to cyber-attacks

Anass Taoufik, Michael Defoort, Mohamed Djemai, Krishna Busawon

In this paper, a distributed methodology is proposed for attack detection and isolation in multi-agent systems (MAS) with high order integrator dynamics. The proposed methodology is capable of detecting an attack on a node/agent and on an edge/communication link anywhere in the fleet and identify…

Nanofluids dynamic viscosity evolution using high-frequency acoustic waves: application applied for droplet evaporation

Ibrahim Zaaroura, Malika Toubal, Julien Carlier, Souad Harmand, Bertrand Nongaillard

Many interests are shown on nanofluids as it's suitable for cooling applications. Knowing the physical properties of nanofluids such as viscosity plays a key role in practical heat transfer situations. The main goal of this work is to measure the dynamic viscosity of Gold nanofluids during…

Study of the evaporation kinetics of pure and binary droplets: volatility effect

Walid Foudhil, Pin Chen, Kamel Fahem, Souad Harmand, Sadok Ben Jabrallah

This work presents a study on the evaporation of a volatile liquid droplet placed on a substrate and surrounded by air. We consider in this work the case of a pure liquid droplet (water, ethanol and butanol), and the case of a binary mixture droplet (water-ethanol and water-butanol). The aim of…
