The design of key nonlinear systems often requires the use of expensive blackbox
simulations presenting inherent discontinuities whose positions in the variable space cannot …

This article introduces an hp hp‐adaptive multi‐element stochastic collocation method,
which additionally allows to re‐use existing model evaluations during either hh‐or pp …

This article focuses on the stochastic modeling of nonlinear systems featuring discontinuities
in their response surface. More specifically, original developments are presented to improve …

All shallow water hydro-sediment-morphodynamic (SHSM) models are prone to uncertainty
arising from inadequate representation of the underlying physics and error in input …

A non-intrusive method to get a multi-element Polynomial Chaos model is developed. This
method is called ME-ACD, for Multi-Element based on Agglomerative Clustering on …

In the study of dynamical and physical systems, the input parameters are often uncertain or
randomly distributed according to a measure $\varrho $. The system's response $ f $ pushes …

Un système mécanique non linéaire est dit non régulier lorsque ses champs de vitesses ou
d'accélérations présentent des discontinuités. Tout système mécanique dont des …

Flight Dynamics aims at studying the motion of an aircraft modelled as a solid. The
equations of motion are gathered in a dynamical system of coupled Ordinary Differential …

Les travaux de doctorat présentés dans ce mémoire ont permis de développer deux
méthodes dédiées à la modélisation stochastique des roues aubagées dans des contextes …

La thèse s' intéresse à une problématique concrète de sécurité des aéronefs. Le domaine
de vol post-décroché est un domaine aérodynamiquement complexe où l'écoulement autour …
