Ce mémoire porte sur les différences entre les genres sur l'adoption des nouvelles technologies en utilisant le modèle TAM (technology acceptance model), nous analysons ces différentes variables et le genre. De plus, nous avons redéfini le modèle du TAM, en y intégrant certaines variables supplémentaires que nous avons trouvé dans la littérature traitant du TAM et de ces variantes. Les variables testées sont l'auto-efficacité, l'expertise informatique, l'anxiété informatique, la perception de facilité d'utilisation, la perception d'utilité et l'intention future d'utilisation. Nous avons utilisé un questionnaire en ligne et avons fait passer un tutoriel sur un logiciel de dessin. En effectuant une série de test statistique, nous pouvons observer que la différence entre les femmes et les hommes n'est pas significative sur toutes les variables, et que l'interaction entre les différentes variables peut fortement interagir sur les différences de genre.
Développer les compétences numériques des étudiants est une tâche importante de l’université d’aujourd’hui. Pour soutenir et motiver les étudiants dans cette optique, nous travaillons à la création d’un système ayant deux objectifs : aider les étudiants à choisir leurs outils informatiques selon leurs activités d’apprentissage et les aider à démarrer leurs tâches de travail avec les outils choisis. Cet article explicite les motivations et les résultats obtenus, tant pédagogiques que technologiques, pour chacune des composantes principales de ce système d’aide. Une collection de fiches sur les tâches de travail des étudiants et leurs outils TIC est le cœur de notre système en matière de ses contenus. Ces fiches doivent pouvoir être utilisées « à la carte » au travers de cours-ateliers ou d’un apprentissage en autonomie. Notre perspective pédagogique principale est d’augmenter le niveau de culture numérique des étudiants et de les aider à mieux réussir leurs études. Il s’agit aussi de valoriser l’importance des compétences transversales développées durant un cursus universitaire.

An important problem that many large organizations face today concerns the support and evolution of their large (legacy) information systems. In this paper we present an approach for migrating large and interdependent legacy information systems to CORBA based platforms. Our approach allows continuous availability of the information systems, minimal manpower for the implementation and preservation of the autonomy of the independent information systems. The information systems of ABB AG serve as case study for the presentation of our approach.
The most important problem that decision makers face in today's ever increasing information flux is how to find efficiently and fast the useful information. Hypermedia Electronic Publishing systems, supporting active information distribution and offering hypertext browsing facilities, provide a promising solution to this problem. Nevertheless several issues, like value added services, retrieval and access mechanism, information marketing as well as financial and security aspects should be resolved before Hypermedia Electronic Publishing systems can be accepted by the information consumers and producers
Cell, a model for strongly Distributed Object Based systems is discussed. Its components, the nucleus and the membrane, are presented and their characteristics are described. The notions of trading and type transparency in the context of the Cell model are described and issues related to their design and implementation are presented.
One of the most important part of the Distributed Musical Rehearsal project was the evaluation of the overall system performance. This task required the development of precise methodology, based on both subjective and objective performance measurements. The results of the evaluation are presented in the report in their raw form and from these we draw our conclusion concerning the quality, usability and possible improvement of the Distributed Rehearsal System.
Hovering information is a new concept denoting information that stays attached to a specific geographical location rather than to a specific host. As a result, when deployed over a mobile set of peers, hovering information than ”hovers” from host to host in order to remain attached to its location. This paper describes the hovering information concept and its characteristics, and then highlights dependability requirements related to this type of information dissemination.
This paper introduces the Spatial Memory concept which defines any geographical location as a memory where information can be stored and retrieval by user-applications. The Hovering Information Middleware is also introduced as a constrained implementation of the Spatial Memory concept. This middleware is based on results presented on previous works related with Hovering Information. Two main modules of the middleware are discussed and evaluated, the Storage and the Retrieval Modules. The evaluation is done by simulations using both random-way-point and real mobility patterns. Real mobility patterns are generated with the SLAW real mobility model. The simulations evaluate current storage and retrieval algorithms and outlines the major drawbacks and potential improvements for next milestones.
