XFIRM: un Modèle Flexible de Recherche d'Information pour le stockage et l'interrogation de documents XML

Users looking for precise information do not want it to be drowned by noisy subjects, as it can be the case in long documents. Thanks to their structure, XML documents allow Information Retrieval (IR) systems to retrieve information units, that are not necessarily whole documents. Two main approaches have been proposed in the literature : database-oriented approaches and IR-oriented approaches,...

Expression of alternatively spliced mRNA variants at specific stages of development or in specific cells and tissues contributes to the functional diversity of the human genome. Aberrations in alternative splicing were found as a cause or a contributing factor to the development, progression, or maintenance of numerous diseases. The use of antisense oligonucleotides (ON) to modify aberrant expr...

Modern technologies allow to access to more and more detailed information on human interactions. In this context, the SocioPatterns collaboration has allowed to develop an infrastructure based on radio-identi cation devices, that records human proximity patterns at a ne grained resolution, among voluntary individuals. This infrastructure has been deployed in diverse contexts, such as scienti c ...

In this document we address the problem of autonomous navigation in dynamic unknown environments. The key of the problem is to guarantee safety for all the agents moving in the space (people, vehicles and the robot itself) while moving toward a predefined goal. In contrast with static or controlled environments, high dynamic environments present many difficult issues: the detection and tracking...
