L’introduction des jeux-vidéo sérieux comme soutiens pédagogiques dans le domaine de l’enseignement est un processus de plus en plus démocratisé. En parallèle de cette introduction, la recherche en ”game studies” représente une discipline académique très active qui s’intéresse à l’analyse des systèmes vidéoludiques complexes, notamment en ce qui concerne la compréhension de l’expérience des jou...

In ebXML the choreography of a business process should be modeled by UMM (UN/CEFACT Modeling Methodology) and is finally expressed in BPSS (Business Process Specification Schema). Our analysis of UMM and BPSS by workflow patterns shows that their expression power is not always equivalent. We use the workflow patterns to specify the transformation from UMM to BPSS where possible. Furthermore, th...

Alternate-level-of-care (ALC) days represent hospital beds that are taken up by patients who would more appropriately be cared for in other settings. ALC days have been found to be costly and may result in worse functional outcomes, reduced motor skills and longer lengths of stay in rehabilitation. This study examines the factors that are associated with acute care ALC days among patients with ...

Ce mémoire de thèse porte sur la conception, la validation, et l’application du codage canal en mode relais dans le candre de système WiFi. A cette fin, le modèle de transmission coopératif est introduit dans le chapitre 1. Pour l’application d’une diversité de coopération, il est nécessaire de mettre en oeuvre le codage et le décodage de code spatiotemporel. C’est l’objet du chapitre 2 qui se ...

In this Note, we consider the 1-dimensional wave equation, discretized by means of Glimm’s random choice method. We prove that for almost every choice of the random parameter, the observability estimate is true asymptotically, uniformly with respect to the discretization parameters. To cite this article: J.-M.

A total of 1752 strains of osrnophilic yeasts were isolated from honey and po]]ens. Fody-three strains Gf esmophilic yeasts produced po]yols, among whieh 6 strains produced erythritol in good yields. On the other hand, 52 osmophilic yeasts converted sucrose te fin]etooligosaccharides, among which 8 strains produced both extra and intracel]ular P-fructofuranosidase, which conyerted sucrose to fr...

Many species of tachinid flies are viewed as generalist parasitoids because what is apparently a single species of fly has been reared from many species of caterpillars. However, an ongoing inventory of the tachinid flies parasitizing thousands of species of caterpillars in Area de Conservación Guanacaste, northwestern Costa Rica, has encountered >400 species of specialist tachinids with only a...

Aggressive signals should predict whether the sender of the signal will attack the receiver, yet this criterion has been little studied. We conducted experiments with male House Wrens (Troglodytes aedon) in northcentral Illinois in 2009 to test the hypothesis that rates of song delivery and wing-quivering (putative aggressive signals) signal aggressive intent. We simulated a conspecific territo...
