Résolution d'un problème de contact avec frottement en présence de variabilités paramétriques

Franck Massa, Thierry Tison, Hai Do, Olivier Cazier, Bertrand Lallemand

Cet article présente une stratégie permettant de résoudre un problème de contact avec frottement en présence de variabilités paramétriques. Pour ce faire, la recherche de l'ensemble des comportements extrêmes des solutions mécaniques, telles que les déplacements ou les efforts de contact, vis-…

Stability analysis of switching TS models using α-samples approach

Zsofia Lendek, Jimmy Lauber, Thierry-Marie Guerra, Paula Raica

In this paper we consider stability analysis of discrete-time switching systems represented by Takagi-Sugeno fuzzy models. For the analysis we use a switching Lyapunov function defined on the switches. In order to develop stability conditions, we consider the variation of this function along…

Upgrade of Corrosiveness Nature of Fish Waste Bio-Oil Using a Hybrid Catalyst (MgO/Na2CO3) Optimization Process

Nadia Mrad, Fethi Aloui, Mohand Tazerout

In this work, catalytic cracking of waste fish oil (WFO) to bio-fuel for ă diesel engine was studied over hybrid catalysts (Sodium carbonate ă Na2CO3/Magnesium oxide). The experiments were conducted using a fix-bed ă reactor. The effect of catalyst-to-WFO ratio and the amount of each ă catalyst…

Control of Haptic Systems with Time-varying Delay

Quoc Viet Dang, Laurent Vermeiren, Antoine Dequidt, Michel Dambrine

This paper addresses the stable implementation of high stiffness interactions of objects in the virtual environment. The virtual wall is modeled as a mechanical system including a linear spring characterized by a virtual stiffness and a damper with a virtual damping in parallel. A novel approach…

Vers la modélisation des assemblages rivetés par super-éléments finis en dynamique rapide

Claire Hennuyer, Nicolas Leconte, Bertrand Langrand, Eric Markiewicz

Lorsqu'une structure aéronautique est soumise à des sollicitations de dynamique rapide, des phénomènes de localisation des contraintes apparaissent au niveau des assemblages rivetés. L'analyse par éléments finis du comportement de la structure complète de l'avion implique…

Alternative Action Plan Generator (A2PG) for elaboration an anticipated feedback

Wided Ben Yahia, Nicolas Tricot, Philippe Polet, Frédéric Vanderhaegen

This paper proposes an original Alternative Action Plan Generator – A2PG, which predicts possible alternatives of the human action plans in which the human operators do not respect the safety rules. These alternatives build an anticipated feedback. Five parameters characterize A2PG. The creation of…

Liquid hydrocarbon fuels from fish oil industrial residues by catalytic cracking

Nadia Mrad, Maria Paraschiv, Fethi Aloui, Edwin Geo Varuvel, Mohand Tazerout, Sassi Ben Nasrallah

In the present work, catalytic cracking of fish oil industrial residue was investigated to study the effect of temperature, type of catalyst and the heating rate on the yield of organic liquid fraction (OLF) and its acid value. The highest bio-oil yield of 72% (wt.) was obtained at temperature…

Sociotechnical systems resilience : a dissonance engineering point of view

Jean-René Ruault, Frédéric Vanderhaegen, Christophe Kolski

Resilience deals with the capacity to adjust itself face disturbing events, to cope with unforeseeable conditions. Resilience is based upon the dynamic process of "visual piloting". The gap between the specified task and the done activity generates dissonance between beliefs and…

Investigation of the performance of modified TCM scheme for the protection of SPIHT-based compressed images over fading channel

Mohamed Ben Aissa, Abdesselam Bassou, Mohammed Beladgham, Abdelmalik Taleb-Ahmed, Abdelmounaim Moulay Lakhdar

In this paper, a new variant of trellis-coded modulation with Ungerboeck-Gray mapping 'TCM-UGM' is presented for spectral efficiency of 2 bit/s/Hz. The performance of this encoding scheme is investigated over Rayleigh fading channel. The simulation result, using 16-state TCM-UGM encoder,…
