The transport properties of a coherent wave in a disordered medium are inherently determined by interference of multiple scattering paths, which can lead to spatial localization and absence of diffusion. This effect, known as Anderson localization, was first predicted for electrons in disordered crystals and then extended to classical waves, which permitted its observation in a variety of syste...

Modélisation de la Structure Complexe des Faits et des Mesures

Decision support system (DSS) goal is to help decision-makers. They are modeled mainly in a multdimiensional way, that means activity analysis subjects, called facts, with their measures are represented as the center of a star with dimensions and their parameters around. Several models have been devoted to DSS representation, but they handle only relationships between dimensions and their param...

Indexation et représentation comparative : application au discours électoral
