Sujet de thèse : Combinatoire des tableaux escaliers

Les tableaux de permutation sont des objets récents introduits par L. Williams (Harvard) [22]. Ils sont une sous-classe des Γ -diagrammes introduits A. Postnikov (MIT) [19] pour l’énumération des cellules totalement positives ou nulles de la Grasmannienne. Voulant généraliser des travaux de E. Duchi (LIAFA, Paris 7) et G. Schaeffer (LIX) [11], R. Brak et al. [1] ont travaillé sur les aspects co...

Masters Topic (Sujet de Stage Master 2005)

General Presentation of the Research Domain The focus of the REVES research group is on image and sound synthesis for virtual environments. Our research is on the development of new algorithms to treat complex scenes in real time, both for image rendering (for example the capture and rendering of trees using an image-based technique [1]) or for sound (for example using perceptual masking and cl...

Sujet de thŁse de doctorat Model Ageing Fuel cell System

Context A wide deployment of the fuel cell systems (FCS) cannot be achieved unless these systems are competitive with conventional solutions in terms of performance, cost and lifetime. As a matter of fact, the FCS must offer good performance and reliability at acceptable cost. Therefore, it is necessary to develop robust systems that are tolerant to faults with a minimal ageing rate. It is ther...

Nonparametric Techniques for Bayesian Filtering Proposition de sujet de recherche

1 Résumé Stochastic filtering refers to an issue for estimating the latent variables from the observations using a stochastic model. Since it was developed in early 1940s, filtering has been one of the most practical tools in the science and engineering field. One of the best known filtering algorithms is a class of Gaussian Filters. However, its gaussian assumption for posterior distribution s...
