Etude numérique d'équations aux dérivées partielles non linéaires et dispersives

2011

Numerical analysis becomes a powerful resource in the study of partial differential equations (PDEs), allowing to illustrate existing theorems and find conjectures. By using sophisticated methods, questions which seem inaccessible before, like rapid oscillations or blow-up of solutions can be addressed in an approached way. Rapid oscillations in solutions are observed in dispersive PDEs without dissipation where solutions of the corresponding PDEs without dispersion present shocks. To solve numerically these oscillations, the use of efficient methods without using artificial numerical dissipation is necessary, in particular in the study of PDEs in some dimensions, done in this work. As stud…

Study of students' motivation to perform learning tasks using the educational virtual environment Silva Numerica

2022

This document presents the modalities of realization and the results of two experiments of the use of the EVE Silva Numerica with students of 1st technological STAV. It shows the impact of different scenarios of use of this EVE with regard to a scenario using a video resource on the regulation of student motivation during a teaching/learning session concerning concepts relating to forest development (environment and competition). It is based on the model developed by the self-determination theory - SDT (Deci and Ryan, 1971, 1975, 1985, 1991) and reworked by Vallerand et al. (1989) in the context of the development of the educational motivation scale (EMS), a tool on which we based our data …

Experimental and numerical study on composites laminates subjected to multi-impacts

2019

Composite carbon/epoxy materials are widely used in the industrial field as aeronautics and as land transport. These materials are often subjected to increasingly stringent conditions of use. They must withstand multiple impacts, the impact of objects such as hailstones, ballast, or even birds.In order to offer designers of composite structures relevant designing elements, we are interested in the first experimental time of the multi-impact tolerance of different stratifications (QIQH45, QIQH60, AERO) of different energies (10J, 15J, 20J). The study of these two parameters made it possible to define a hierarchy among the stratifications studied with the level of damage.The evaluation of the…

Espace public numérique et participation politique

2015

International audience; L’arrivée massive des technologies de l’information et de la communication et la démocratisation d’Internet dans la vie quotidienne ont restructuré notre société. La relation aux autres se trouve reconfigurée par l’émergence de nouvelles formes de communication interpersonnelle et communautaire, désormais fréquemment « assistée par ordinateur ». La différence réside dans l’échelle des valeurs engendrées (nombre d’individus en contact, pluralité des individus, nature des informations…) et particulièrement dans la puissance du canal de communication qui brouille les frontières de l’espace public, modifie les temporalités et réinterroge la participation politique et cit…

L’amour aux temps d’Internet : raison et émotion dans la recherche de partenaire en ligne des Chiliens

2017

This study analyzes the pages of online dating, more specifically, the interpretation that Chilean surfers perform these virtual spaces; interactions that occur within these web portals; and the sense that national users associate with their interactions. To answer these objectives not only a number of methods of collection and analysis of information is used, but in turn, the data generated is inserted in a wide theoretical discussion about love and relationships. Thus, in the first part of this work, the imagery of love is analyzed from its main myths and stories. Subsequently the historical and sociological constitution of relationships is analyzed. Epistemological, methodological and et…

Recherche d'information dans les documents numériques : vers une variation des modalités d'exécution procédurale

2011

National audience; L'objectif de la recherche présentée est de tester l'efficacité cognitive d'un nouveau système technique facilitant la recherche d'information dans les documents numériques. Ce système utilise un dispositif de prévisualisation par transparence permettant à l'utilisateur de consulter aisément des pages en profondeur. Une étude expérimentale a été conduite auprès de 36 participants, dont 26 étudiants et 10 personnes âgées. La tâche de recherche d'information consistait à trouver un appartement cible possédant un ou plusieurs critères spécifiques dans un site web d'agence immobilière spécialement conçu et contrôlé pour l'étude. Deux versions de ce site ont été testées. L'une…
