Current configuration detection in hybrid systems: Application to a conjunction–disjunction mechatronics system

Fayssal Arichi, Cherki Brahim, Mohamed Djemai

This paper deals with the problem of detecting the current conﬁgurations of hybrid mechatronic systems, where theevolution of the discrete part is governed by a Petri net. The considered class of systems may have several subsystems,with diﬀerent dimensions, evolving at the same time. The current…

Active modes and switching instants identification for linear switched systems based on Discrete Particle Swarm Optimization

Sahbi Boubaker, Mohamed Djemai, Noureddine Manamanni, Faouzi M'Sahli

n this paper, a methodology for identifying switching sequences and switching instants of switched linear systems (SLS) is derived. The identification problem of a SLS is a challenging and non-trivial problem. In fact, it involves interaction between binary, discrete and real-valued variables. A…

Roughness statistical influence on cell adhesion using profilometry and multiscale analysis

Sylvain Giljean, Maxence Bigerelle, Karine Anselme

In this study, two series of 11 samples of TiAl6V4 titanium alloy and 316L stainless steel have been polished in an isotropic manner at different levels in order to quantify the influence of biomaterial roughness on cell behavior. Topography was measured by a tactile profilometer and a multiscale…

Full Body Adjustment Using Iterative Inverse Kinematic and Body Parts Correlation

Ahlem Bentrah, Abdelhamid Djeffal, Mc Babahenini, Christophe Gillet, Philippe Pudlo, Abdelmalik Taleb-Ahmed

In this paper, we present an iterative inverse kinematic method that adjust 3D human full body pose in real time to new constraints. The input data for the adjustments are the starting posture and the desired end effectors positions -constraints-. The principal idea of our method is to divide the…

A multiple-metric QoS-aware implementation of the optimized link state routing protocol

Patrick Sondi, Dhavy Gantsou, Sylvain Lecomte

The optimised link state routing (OLSR) protocol is one of the most promising for mobile ad hoc networks (MANETs). Despite numerous proposals for quality of service in MANET, there is a lack of OLSR implementations that efficiently support applications with stringent QoS constraints like VoIP or…

Etude des imaginaires suscités par des jeux vidéo de premières générations, Study of players imaginary related to first generations of video games

Julian Alvarez, Sylvain Haudegond

Dans la perspective d’étudier l’usage et l’évaluation associés au Serious Game dans un contexte d’enseignement, il convient de vérifier entre autres si les joueurs de différentes générations expriment des imaginaires différents lorsqu’ils sont exposés à des objets vidéoludiques. En effet, un…, In view to study the use and evaluation associating Serious Games in the context of education, should one consider whether players from different generations have different imaginaries when they are exposed to video games. Indeed, a teacher, because he has known video games from first generations,…

An experimental analysis and modeling of the work-softening transient due to dynamic recrystallization

Eli Saúl Puchi-Cabrera, M.H. Staia, Jean-Dominique Guerin, Jacky Lesage, Mirentxu Dubar, Didier Chicot

The flow softening brought about by dynamic recrystallization (DRX) during the plastic deformation of metals and alloys under hot-working conditions is of a great practical significance for the computation of the loads, torques and power consumption required in industrial hot forming operations.…

Adaptation de l'ergonomie prospective aux systèmes à longue durée de vie

Jean-René Ruault, Emmanuel Gardinetti, Christophe Kolski, Frédéric Vanderhaegen

L’ergonomie prospective dont l’objectif est d’anticiper les besoins et activités des humains dans le but de créer de nouveaux artefacts, complète les concepts, méthodes et outils de l’ergonomie corrective et de l’ergonomie préventive pour répondre aux enjeux actuels des artefacts innovants et des…

Toward the modelling of riveted assemblies by super-elements in fast dynamics

Claire Hennuyer, Nicolas Leconte, Bertrand Langrand, Eric Markiewicz

The finite element analysis of the behaviour of airframes subjected to crash or impact loadings requires the use of suitable finite elements, in particular for the modelling of riveted assemblies. In order to predict the structure survivability, it is indeed necessary to focus on these areas…, L’analyse par éléments finis du comportement des structures aéronautiques soumises au crash ou à l’impact requiert l’utilisation d’éléments finis adaptés, en particulier pour la représentation des assemblages rivetés. Afin de prédire la survivabilité de la structure, il est en effet nécessaire de s…

COMMON FRAMEWORK : A HYBRID APPROACH TO INTEGRATE CROSS-PLATFORM COMPONENTS IN MOBILE APPLICATION

Joachim Perchat, Mikael Desertot, Sylvain Lecomte

There is a multitude of mobile OS: iOS android, Windows Phone 8 and each OS provides its own standards and tools. This heterogeneity in the mobile domain forces developers to implement an application for each mobile platform. To achieve that, developers need to master several languages (Java,…
