LU-factorization and probability
Our initial motivation was to understand links beetween $\mathtt{WH}$-factorizations for random walks and $\mathtt{LU}$-factorizations for Markov chains has... -
Large deviations for self-intersection local times of random walks
In this thesis we are interested in the self-intersection local times of random walks. This quantity is defined as the $p$-norm to the power of $p$ of the local times... -
The number of generations entirely visited for recurrent random walks on rand...
In this paper we are interested in a random walk in a random environment on a super-critical Galton-Watson tree. We focus on the recurrent cases already studied by Y.... -
Modélisation Multi-échelle de l'infiltration chimique à partir de la phase va...
Ceramic matrix composites and carbon fiber reinforced carbon composites are dedicated to high temperature applications. They consist of a stacked fibrous arrangement,... -
Random walks and first-passage properties: Trajectory analysis and search opt...
First-passage properties in general, and the mean first-passage time (MFPT) in particular, are widely used in the context of diffusion-limited processes. Real... -

Dynamics in the Sherrington-Kirkpatrick Ising spin glass at and above T-g
A detailed numerical study is made of relaxation at equilibrium in the Sherrington-Kirkpatrick Ising spin glass (ISG) model, at and above the critical temperature T-g.... -
Statistical modeling of diffusive and thigmotactic random walks in heterogene...
Social insect nests are fascinating because, as complex and organized they may be, they are built in a self-organized way by insects who can be several orders of... -

Simulation of chemical vapor infiltration and deposition based on 3D images :...
A numerical solution for the simulation of chemical vapor infiltration (CVI) of ceramic matrix composites is presented. This computational model requires a 3D... -
Résolution numérique du problème de Dirichlet $\Delta u = a\,u^3$ à l'aide du...
In this paper, we are interested in numerical solution of some linear boundary value problems with Dirichlet boundary part, by the means of simulation of random walks.... -
Discriminative Parameter Estimation for Random Walks Segmentation: Technical ...
The Random Walks (RW) algorithm is one of the most e - cient and easy-to-use probabilistic segmentation methods. By combining contrast terms with prior terms, it... -
