Fast and accurate multi-material model for the prediction of laser welded structural response

Waseem Arif, Hakim Naceur, Sajjad Miran, Nicolas Leconte, Eric Markiewicz

Purpose The purpose of this study is to develop an elasto-plastic multi-material shell model by which finite element analysis of laser welded joints is carried out at the interface of the heat-affected zone and base material. Design/methodology/approach The multi-material shell model is implemented…

Predefined-time convergence in fractional-order systems

Aldo-Jonathan Muñoz-Vázquez, Juan Diego Sanchez-Torres, Michael Defoort, Salah Boulaaras

The contribution of this paper is the design of a novel controller that enforces predefined-time convergence in fractional-order systems, which are defined by means of the Caputo derivative, whose order lays between zero and one. The controller is based on a dynamic extension, which induces an…

Weak Signal-Oriented Investigation of Ethical Dissonance Applied to Unsuccessful Mobility Experiences Linked to Human–Machine Interactions

Frédéric Vanderhaegen

Ethical dissonance arises from conflicts between beliefs or behaviors and affects ethical factors such as normality or conformity. This paper proposes a weak signal-oriented framework to investigate ethical dissonance from experiences linked to human–machine interactions. It is based on a systems…

Corticomuscular Coherence and Motor Control Adaptations after Isometric Maximal Strength Training

Dimitri Elie, Franck Barbier, Ghassan Ido, Sylvain Cremoux

Strength training (ST) induces corticomuscular adaptations leading to enhanced strength. ST alters the agonist and antagonist muscle activations, which changes the motor control, i.e., force production stability and accuracy. This study evaluated the alteration of corticomuscular communication and…

Experimental studies on evaporation kinetics of gold nanofluid droplets: Influence of nanoparticle sizes and coating on thermal performance

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

In this work, a series of experiments investigate the evaporation of gold nanofluid sessile droplets on a perfluorodecyltrichlorosilane (PFTS) silicon substrate heated to 77 °C. The evaporation processes of different nanofluid droplets of the same initial volume, all for a 1% Cv volume…

Thèse

Etude de la modulation des interactions corticomusculaires et intermusculaires induite par l'entraînement de force maximale chez le sujet sain, Study of the modulation of corticomuscular and intermuscular interactions induced by maximal strenght training in the healthy subject

Dimitri Elie

Les premières semaines d’entraînement conduisent à une augmentation rapide de la production de force maximale et/ou de la précision contrôle moteur. Ces adaptations comportementales sont supposées résulter d’adaptations neurophysiologiques puisque la structure musculaire reste inchangée. Ces…, The first few weeks of training lead to a rapid increase of the force production and / or motor control precision. These behavioral adaptations are believed to result from neurophysiological adaptations since muscle structure remains unchanged. These neurophysiological adaptations could be…
