Representation of thermal building simulation in virtual reality for sustainable building

2014

The importance of energy efficiency as well as integration of advances in sustainable buildingdesign and VR technology have lead this research to focus on thermal simulation results visualized in avirtual environment (VE). The emphasis is on the representation of thermal building simulation (TBS)results and on the perception of thermal data simulated in a VE. The current application of the designprocess through energy efficiency in VR systems is limited mostly to building performance predictionsand design review, as the issue of the data formats and the workflow used for 3D modeling, thermalcalculation and VR visualization.Different applications and tools involved to represent TBS in VE are…

Comment évaluer et mesurer la conflictualité liée aux usages de l'espace ? Eléments de méthode et de repérage

2010

Cet article a pour objet de présenter le travail réalisé depuis quelques années par une équipe pluridisciplinaire sur la question des conflits d’usage de l’espace et de révéler la méthodologie d’enquête et de collecte de données, ainsi que la structure de la base de données qui en est issue. Dans un premier temps nous procédons à une définition du champ des investigations, en donnant une définition de ces conflits, de leurs caractéristiques, des mobiles et des manifestations de la conflictualité, ainsi que des acteurs impliqués (I). Nous exposons ensuite notre méthode de repérage des conflits, fondée sur un diagnostic de zone et la mise en commun de différentes méthodes de recueil de donnée…

Urban densities and economic analyse of residentials choices

2016

The thesis is focused on urban growth control challenge through the Compact City model and its key spatial characteristic: the density. This work deals both with a theoretical, methodological and empirical approach. First, we place ourselves in the theoretical framework of Urban Economic addressing agents’ location choices. We mobilize these theories to identify the key determinants of residential location (employment center, spatial amenities, housing’s service) and analyze the spatial organization that follows (dense or spread). This literature leads us to consider different types of density: structural density, population density and social density. This thesis highlights various methodo…

Stochastic algorithms for robust statistics in high dimension

2016

This thesis focus on stochastic algorithms in high dimension as well as their application in robust statistics. In what follows, the expression high dimension may be used when the the size of the studied sample is large or when the variables we consider take values in high dimensional spaces (not necessarily finite). In order to analyze these kind of data, it can be interesting to consider algorithms which are fast, which do not need to store all the data, and which allow to update easily the estimates. In large sample of high dimensional data, outliers detection is often complicated. Nevertheless, these outliers, even if they are not many, can strongly disturb simple indicators like the me…

Survey sampling for functionnal data : building asymptotic confidence bands and considering auxiliary information

2011

When collections of functional data are too large to be exhaustively observed, survey sampling techniques provide an effective way to estimate global quantities such as the population mean function, without being obligated to store all the data. In this thesis, we propose a Horvitz–Thompson estimator of the mean trajectory, and with additional assumptions on the sampling design, we state a functional Central Limit Theorem and deduce asymptotic confidence bands. For a fixed sample size, we show that stratified sampling can greatly improve the estimation compared to simple random sampling. In addition, we extend Neyman’s rule of optimal allocation to the functional context. Taking into accoun…

Contribution of virtual reality to functional rehabilitation

2010

Virtual reality has grown immensely. Practical applications for the use of this technology encompass many fields in both engineering science and human science. In the field of medicine, one of the newest fields to benefit from the advances in VR technology, virtual reality has become a major new therapeutic tool not only in medicine and surgery but also for the treatment of psychological disorders and rehabilitation for impaired person. Our research presented in this thesis aims at developing utilities to aid in functional rehabilitation using virtual reality technology. The main research question of our work concerns the effect of virtual metaphors in learning and training human gestures f…

Classification par méthodes d’apprentissage supervisé et faiblement superviséd’images multimodales pour l’aide au diagnostic du lentigo malin en derm…

2021

Carried out in collaboration with the Saint-Étienne University Hospital, this work provides additional information to help the skin diagnosis by providing new decision methods on Lentigo Maligna and Lentigo Maligna Melanoma pathologies. To this end, the modalities regularly used in clinical conditions are made available to this work and are orchestrated within a multimodal process. Among image modalities, may be mentioned the clinical photography, the dermatoscopy, and the confocal reflectance microscopy. Initially, the first steps of this manuscript focus on reflectance confocal microscopy as the work in computer diagnostic assistance is relatively underdeveloped, in particular on the dete…
