Sur la théorie spectrale locale des shifts à poids opérateurs

Nous étudions les propriétés spectrales locales du shift unilateral à poids opérateurs. Nous donnons une condition nécessaire et suffisante pour que l’adjoint satisfasse la propriété de l’extension unique (SVEP). Une condition suffisante pour satisfaire la propriété de Dunford (C) ainsi qu’une condition nécessaire pour satisfaire la condition de Bishop (β) seront données. Enfin, nous montrons q...

Utilisation de la théorie des graphes et de la distance d'édition pour la recherche d'information sur documents XML

Information retrieval on semi-structured documents like XML (SIR) allows the user to narrow his search down to the document element level. Queries and semi-structured documents could be seen as hierarchically nested elements. We consider that their structural proximity could be evaluated over their trees similarity. Our SIR approach combines both content and structure scores, the latter being b...

Une approche pour la simulation de comportements émotionnels fondée sur la théorie de la conservation des ressources

The simulation of believable behaviours for virtual agents requires to take human factors such as emotions into account. Most computational models dealing with this subject include emotion categories in their architecture. However, determining the number of categories to use and their influence on behaviour is a difficult task. In this paper, we present a model without emotion categories, cente...

Genèse de la théorie cellulaire

or represent aspects of nature or the language-user's own general or circumstantial experience. In his book Professor Bazerman rarely avoids assuming as obvious the distinction between language and that which language is about, so that statements like the following are typical: "Experimental reports attach themselves to the nature that surrounds the text through the representation of the doings...
