Stochastic model for an uncertain rigid body of a multibody dynamical system
This research is devoted to the construction of a stochastic model for an uncertain rigid body of a multibody dynamical system. Sometimes the mass distribution of a... -
MaxEnt approach for the probabilistic modeling of matrix-valued random fields...
This work is devoted to the construction of a class of prior stochastic models for non-Gaussian positive-definite matrix-valued random fields, having recourse to the... -
A stochastic multiscale approach to deal with the homogenization of random no...
we address the construction of random macroscopic constitutive laws by homogenization of random nonlinear heterogeneous materials for which a high number of random... -
Sub-ballistic random walk in Dirichlet environment
We consider random walks in Dirichlet environment (RWDE) on $\Z ^d$, for $ d \geq 3 $, in the sub-ballistic case. We associate to any parameter $ (\alpha_1, \dots,... -
Identification of the probabilistic model for a non-homogeneous cortical bone...
The mean elasticity properties of the cortical bone in the thickness is not a constant but have spatial fluctuations due to damages in the cortical bone microstructure... -
Multibody system dynamics with uncertain rigid bodies
The mass, the center of mass and the tensor of inertia which describe the rigid body are uncertain and are then modeled by random variables. The probability... -
Experimental identification in the ultrasonic range of a probabilistic model ...
The probabilistic model is constructed by using the information theory and the maximum entropy principle. This probabilistic model exhibits a minimum number of... -

Identification of polynomial chaos representations in high dimension
The usual identification methods of polynomial chaos expansions in high dimension are based on the use of a series of truncations that induce numerical bias. We first... -
