Analyse non standard du bruit

Analyse non standard du bruit

Noises: a nonstandard analysis. Thanks to the nonstandard formalization of fast oscillating functions, due to P. Cartier and Y. Perrin, an appropriate mathematical framework is derived for new non-asymptotic estimation techniques, which do not necessitate any statistical analysis of the noises corrupting any sensor. Various applications are deduced for multiplicative noises, for the length of t...

Étude du bruit dans une analyse M -bandes en arbre dual

In this work, we study the properties of an additive noise undergoing a dual-tree M -band wavelet analysis. We express the relationships governing noise coefficients both in the primal and the dual tree. The knowlegde of the noise statistical properties is particularly useful for the design of efficient denoising methods in the framework of a dual-tree wavelet analysis. Our main contribution co...

Analyse Automatique Du Doigté Au Piano

Le choix d’un doigté a une influence certaine sur le jeu au piano. S’il est généralement un compromis entre des contraintes physiques et interprétatives, la composante physique a la priorité quand il s’agit de passages musicaux très rapides et techniques. Cet article présente une méthode originale pour trouver automatiquement le doigté optimal d’une mélodie dans ce contexte. En se fondant sur d...

Analyse territoriale du bien-être avec HyperAtlas

This paper questions the definition and analysis of sustainable wellfare indicators. We first present the context and issues of such matter. Then, we compare HyperAtlas, a generic tool for multiscalar territorial analysis that we have developed, with the existing softwares that deal with spatial analysis and, among them, some that specifically address wellfare indicators. Therefore, we identify...
