Lighter tableware ceramic by controlling porosity: Effect of porosity on mechanical properties

Benjamin Verhaeghe, Christian Courtois, F. Petit, F. Cambier, Jean-Dominique Guerin, Anne Leriche, Stuart Hampshire

Reduction in weight of ceramics has been achieved by using a specific porous agent, starch, to achieve porosity ranging from 10% to 35%. Two incorporation routes of the porous agent have been investigated. For different levels of weight reduction, ceramics are characterized by microstructural…

Sliding subspace design based on linear matrix inequalities

Alan Tapia, Raymundo Márquez Borbόn, Miguel Bernal, Joaquín Cortez

In this work, an alternative for sliding surface design based on linear and bilinear matrix inequalities is proposed. The methodology applies for reduced and integral sliding mode control, both continuous- and discrete-time; it takes advantage of the Finsler's lemma to provide a greater degree…

Environmental Policy in a Dynamic Model with Heterogeneous Agents and Voting

Kirill Borissov, Thierry Bréchet, Stéphane Lambrecht

We consider a population of infinitely-lived households split into two: some agents have a high discount factor (the patients), and some others have a low one (the impatients). Polluting emissions due to economic activity harm environmental quality. The governmental policy consists in proposing…

Fertilisation croisée entre interaction personne-système et IA

Christophe Kolski, Guy Andre Boy, Guy Melançon, Magalie Ochs, Jean Vanderdonckt

L'IA est d'une certaine manière au coeur des sciences du traitement de l'information. Ce troisième volume a pour objet l'examen des interfaces de l'IA avec différents champs de recherche de l'informatique, tant théorique qu'appliquée, comme les bases de données,…

Dynamic evolution of interface roughness during friction and wear processes

K. J. Kubiak, Maxence Bigerelle, T. Mathia, André Dubois, Laurent Dubar

Dynamic evolution of surface roughness and influence of initial roughness (Sa = 0.282–6.73 µm) during friction and wear processes has been analyzed experimentally. The mirror polished and rough surfaces (28 samples in total) have been prepared by surface polishing on Ti–6Al–4V and AISI 1045 samples…

Expérimentation autour des imaginaires suscités par du rétrogaming, Experimentation around the imaginations aroused by retrogaming

Julian Alvarez, Sylvain Haudegond

Cette communication tente d’étudier si les joueurs pionniers qui ont découvert le jeu vidéo à ses débuts, avec des représentations graphiques très minimalistes, partagent un imaginaire plus riche que les joueurs plus jeunes lorsqu’ils sont exposés à des titres datant des années 1977 à 1984., This communication attempts to study whether pioneer players who discovered video games in their early days, with very minimalist graphic representations, share a richer imagination than younger players when they are exposed to titles dating from 1977 to 1984.

Stochastic Runge-Kutta methods with the constant elasticity of variance (CEV) diffusion model for pricing option

Rajae Aboulaich, Abdelilah Jraifi, Medarhri Ibtissam

In order to solve numerically the constant elasticity of variance (CEV) model for pricing of European call option, we propose in this work the Stochastic Runge-Kutta method. We compare the obtained results using this approache, with those given by the Monte Carlo method in Broadie-Kaya [4]. Further…

On two optimal control problems for magnetic fields

Serge Nicaise, Simon Stingelin, Fredi Tröltzsch

Two optimal control problems for instationary magnetization processes are considered in 3D spatial domains that include electrically conducting and nonconducting regions. The magnetic fields are generated by induction coils. In the first model, the induction coil is considered as part of the…

Ternary Zero Correlation Zone Sequence Sets for Asynchronous DS-CDMA

Benattou Fassi, Ali Djebbari, Abdelmalik Taleb-Ahmed

In this paper we propose a new class of ternary Zero Correlation Zone (ZCZ) sequence sets based on binary ZCZ sequence sets construction. It is shown that the proposed ternary ZCZ sequence sets can reach the upper bound on the ZCZ sequences. The performance of the proposed sequences set in…

Dynamically Reconfigurable Embedded Architectures for Safe Transportation Systems

Naim Harb, Smail Niar, Mazen Saghir

Embedded system designers are increasingly relying on Field Programmable Gate Arrays (FPGAs) as target design platforms. Today's FPGAs provide high levels of logic density and rich sets of embedded hardware components. They are also inherently flexible and can be easily and quickly modified to…
