Les professionnels de l'information traversent actuellement une période de redéfinition de leur profession provoquée par la transformation de l'information et des processus informationnels vers un mode de plus en plus électronique. Les systèmes d'information Web (SIW) — c'est-à-dire des systèmes…

"The discrepancy between [our personal experiences] and our idealizations of knowledge leads us into counterproductive strategies for learning and thinking" (Papert 1993). This discrepancy has driven most research towards understanding how people fail to accomplish a task, while few researchers…

(cont.) to variations in the way functional elements interact with verbal roots. Overall, my work not only contributes to our understanding of how events are syntactically represented, but also explicates interactions at the syntax-semantics interface, clarifying the relationship between surface…

Well-known methods for solving the shape-from-shading problem require knowledge of the reflectance map. Here we show how the shape-from-shading problem can be solved when the reflectance map is not available, but is known to have a given form with some…

(cont.) in the ECS signal, no definitive method for sensing blade vibration using an ECS has yet been developed., High cycle fatigue (HCF) cracks generated by compressor blade vibrations are a common source of failure in gas turbine engines. Current…

Well-known methods for solving the shape-from-shading problem require knowledge of the reflectance map. Here we show how the shape-from-shading problem can be solved when the reflectance map is not available, but is known to have a given form with some…

Morphological analysis requires knowledge of the stems, affixes, combnatory patterns, and spelling-change processes of a language. The computational difficulty of the task can be clarified by investigating the computational characteristics of specific models of morphologial processing. The use of finite-state…

Le développement accéléré des technologies de communication, de saisie et de traitement de l’information durant les dernières années décennies ouvre la voie à de nouveaux moyens de contrôle social. Selon l’auteur Gary Marx ceux-ci sont de nature non coercitive et…
