Optimisation d'un électromyostimulateur intelligent pour le reconditionnement musculaire

2017

This project aims to optimize smart electromyostimulators for the muscular reeducation. The electrostimulator optimization aims to improve the electrostimulation sessions (EMS) by obtaining informations on the muscular electical stimulations and the control application in real time in order to control the muscular response. Various control methods of the muscular force are been developed and applied on an accurate model. In first, the techniques will be applied on the partial model without taking into account the muscular fatigue then in second in taking into account the presence of fatigue and its effects. Theses control methods act on the stimulation parameters in frequency and in amplitu…

Les pratiques pédagogiques des enseignants du secondaire: l'éclairage des comparaisons internationales

2017

International audience; L'objectif de cet article est de comparer, à l'appui des données de l'enquête internationale TALIS, les pratiques pédagogiques des enseignants du second degré de plusieurs systèmes éducatifs (France, Royaume-Uni, Corée du Sud et Finlande) et de proposer des modèles d'analyse de la structure de ces pratiques. Nous montrons qu'il existe une hétérogénéité des pratiques pédagogiques et que les différentes composantes des pratiques entretiennent entre elles des liens statistiquement forts, susceptibles de varier d'un système à l'autre.

Penalization and data reduction of auxiliary variables in survey sampling

2012

Survey sampling techniques are quite useful in a way to estimate population parameterssuch as the population total when the large dimensional auxiliary data setis available. This thesis deals with the estimation of population total in presenceof ill-conditioned large data set.In the first chapter, we give some basic definitions that will be used in thelater chapters. The Horvitz-Thompson estimator is defined as an estimator whichdoes not use auxiliary variables. Along with, calibration technique is defined toincorporate the auxiliary variables for sake of improvement in the estimation ofpopulation totals for a fixed sample size.The second chapter is a part of a review article about ridge re…

Estimation de la relation de salaires de Mincer : choix de specification et enjeux économétriques

2012

In the present doctoral thesis, we estimated Mincer’s (1974) semi logarithmic wage function for the French and Pakistani labour force data. This model is considered as a standard tool in order to estimate the relationship between earnings/wages and different contributory factors. Despite of its vide and extensive use, simple estimation of the Mincerian model is biased because of different econometric problems. The main sources of bias noted in the literature are endogeneity of schooling, measurement error, and sample selectivity. We have tackled the endogeneity and measurement error biases via instrumental variables two stage least squares approach for which we have proposed two new instrum…

Contribution to the study of the recovery of wast heat : study and optimization of Stirling engines

2012

Several machines currently used, internal combustion engines for the car industry or thermal power plants in energy, exhaust a considerable amount of heat. Generally this heat is dispersed in the atmosphere and its energy lost. So we took a special interest in external heat engines which primary energy is heat energy, and more particularly in Stirling engines. One of its main characteristics is the used of energy from heat produced externally like energy source. This allows Stirling engines to be multi-fuel and even to use natural heat energy.The study carried out is made up of two parts. First, a three zones zero dimensional finite-time thermodynamic model has been developed. It takes into…

Numerical modelling of low velocity multi-impact test on different stacking sequences

2019

The use of composite materials in the industrial field has been growing significantly for many years. This increase is explained by the fact that the industry, especially aeronautics which was pioneering in this field, is interested in the lightening of structures in order to be able to take up the new environmental challenges. Whether in the aeronautical field or in the land transport sector, structural elements may undergo multi-impactsor impact. Even at low velocitypose a threat to the integrity of the material and the structure itself. The objective of this work is to propose a numerical model to determine the damage within a composite structure subjected to low energy multi-impact. The…

Cinq facteurs clés pour comprendre les territoires sportifs

2006

Pour expliquer la répartition spatiale des activités sportives et la création de territoires sportifs, cet article envisage cinq facteurs clés qui sont les fondements nécessaires de toute analyse. La répartition de la population introduit un effet de masse sous-jacent à toute pratique d’une activité sportive ; le milieu physique, s’il n’en demeure pas moins indispensable pour comprendre la localisation de certains sports, subit un processus d’artificialisation ; la diffusion spatiale introduit une dimension historique obligatoire ; même contestée, l’influence de l’espace social au sens large se fait ressentir à condition d’utiliser la bonne échelle d’analyse ; enfin, la dynamique spatiale i…
