Principes et étude de cas d'adaptation d'IHM dans les SI en fonction du contexte d'interaction de l'utilisateur

Mohamad-Anas Hariri, Sophie Lepreux, Dimitri Tabary, Christophe Kolski

La mobilité a engendré de nouveaux besoins informatiques. Les téléphones portables, assistants personnels et autres moyens de communications sont désormais utilisés pour l’ensemble des tâches effectuées par les utilisateurs. Les utilisateurs souhaitent utiliser les services spécifiques liés à cette…, With the mobility, new needs have been found. From now on, the cellular phone, the personal assistant and other modern communication means are used by users for realizing their tasks. The users wish using services specific to this mobility and also applications used usually at office. The user…

Baropodometric information return device for foot unloading

Aurélien Descatoire, André Thévenon, Pierre Moretto

Numerous studies on the development of new biofeedback device conception have already been undertaken. The devices are used for some methods of compensation for the data loss on sensors set. Patients with loss of protective pain sensation are unable to modify their gait when abnormal and excessive…

Control Law Proposition for the Stabilization of Discrete Takagi-Sugeno Models

Thierry-Marie Guerra, Alexandre Kruszewski, Miguel Bernal

This paper deals with the stabilization of a class of discrete nonlinear models, namely those in the Takagi-Sugeno form; its main goal is to reduce conservatism of existing stabilization conditions using a special class of candidate Lyapunov functions and an enhanced control law. It is shown that…

Improved convergent heuristics for the 0-1 multidimensional knapsack problem

Saïd Hanafi, Christophe Wilbaut

At the end of the seventies, Soyster et al. (Eur. J. Oper. Res. 2:195-201, 1978) proposed a convergent algorithm that solves a series of small sub-problems generated by exploiting information obtained through a series of linear programming relaxations. This process is suitable for the 0-1 mixed…

Step-to-step reproducibility and asymmetry to study gait auto-optimization in healthy and cerebral palsied subjects, Intérêt de la reproductibilité du pas et de l'asymétrie pour étudier l'auto-optimisation de la marche chez des sujets sains et atteints de paralysie cérébrale

A. Descatoire, Virginie Femery, Francois J Potdevin, Pierre Moretto

ObjectiveThe purpose of our study was to compare plantar pressure asymmetry and step-to-step reproducibility in both able-bodied persons and two groups of hemiplegics. The relevance of the research was to determine the efficiency of asymmetry and reproducibility as indexes for diagnosis and…, Objectif - Le but de notre étude était de comparer l’asymétrie des pressions plantaires et la reproductibilité pas-à-pas chez des personnes valides et dans deux groupes de sujets hémiplégiques en vue de déterminer la pertinence des indices d’asymétrie ou de reproductibilité dans les processus de…

TLR2-dependent eosinophil interactions with mycobacteria: role of alpha-defensins.

Virginie Driss, Fanny Legrand, Emmanuel Hermann, Sylvie Loiseau, Yann Guerardel, Laurent Kremer, Estelle Adam, Gaëtane Woerly, David Dombrowicz, Monique Capron

Peripheral blood and tissue eosinophilia are a prominent feature in allergic diseases and during helminth infections. Eosinophil recruitment also frequently occurs upon mycobacterial infections, particularly in lung granuloma. However, the mechanism by which eosinophils interact with mycobacteria…

Discrete Tagaki-Sugeno models for control: Where are we?

Thierry-Marie Guerra, Alexandre Kruszewski, Jimmy Lauber

This work deals with relaxed conditions for stability and stabilization of discrete-time Takagi–Sugeno (TS) models. It recalls classical results found in the literature which use quadratic Lyapunov functions leading to very conservative conditions, and various extensions based on piecewise and non-…

Discrete-time normal form for left invertibility problem

Mohamed Djemai, Jean-Pierre Barbot, Inam Belmouhoub

This paper deals with the design of quadratic and higher order normal forms for the left invertibility problem. The linearly observable case and one-dimensional linearly unobservable case are investigated. The interest of such a study in the design of a delayed discrete-time observer is examined.…
