Optimal stopping and stochastic control differential games for jump diffusions

Fouzia Baghery, Sven Haadem, Bernt Oksendal, Isabelle Turpin

We study stochastic differential games of jump diffusions driven by Brownian motions and compensated Poisson random measures, where one of the players can choose the stochastic control and the other player can decide when to stop the system. We prove a verification theorem for such games in terms…

Robustness study and reliability growth based on exploratory design of experiments and statistical analysis: a case study using a train door test bench

Laurent Cauffriez, Pierre Loslever, Nathalie Caouder, Fabien Turgis, Reynald Copin

This paper presents a methodology to improve the reliability/robustness of a complex mechatronic system for passenger access, which is greatly stressed over its life cycle. The proposed methodology aims to weed out design problems during the development phase and to test the robustness of the…

Pyroelectric power harvesting using a lead-lanthanum-zirconate-titanate (7/60/40 PLZT) pyroelectric cell

Mounir Amokrane, Arnaud Baysse, Bertrand Nogarede, Mohamed Rguiti

The aim of this work is to study the ability of harvesting energy using a lead-Ianthanum-zirconate-titanate (7/60/40 PLZT) pyroelectric cell. For this purpose, the active element is subjected to temperature variations. The pyroelectric cell is directly connected to a load to realize a resistive…

Robust residual a posteriori error estimators for the Reissner-Mindlin eigenvalues system

Emmanuel Creusé, Serge Nicaise, Emmanuel Verhille

We consider a conforming finite element approximation of the Reissner-Mindlin eigenvalue system, for which a robust a posteriori error estimator for the eigenvector and the eigenvalue errors is proposed. For that purpose, we first perform a robust a priori error analysis without strong regularity…

Plateforme automobile à autonomie augmentée et pilotée sous Zig-Bee

Fabrice Robert, Jean-Paul Becar, Franck Dardy

Le présent papier présente une maquette pédagogique de plateforme automobile pilotée par un système sans fil et assu-rant son autonomie énergétique. C’est précisément l’autonomie énergétique des robots explorateurs sur Mars qui a nour-ri à la fois les questionnements d’étudiants et les idées des…

Robots Collision Avoidance Using Learning through Imitation

Aurel Fratu, Jean-Paul Becar

This paper deals with the collision avoidance of the cooperative robots using the learning through imitation. Each physical robot acts fully independently, communicating with corresponding virtual prototype and imitating her behavior. Each physical robot reproduces the motion of her virtual…

Time-domain study of the Drude–Born–Fedorov model for a class of heterogeneous chiral materials

Serge Nicaise

We deal with the well-posedness of the transient Maxwell equations in a particular class of heterogeneous isotropic chiral material modeled by the Drude-Born-Fedorov constitutive relations with different boundary conditions. A new formulation of the underlying evolution problems allows us to…

A Resonant-Superlinear Elliptic Problem Revisited

Mabel Cuesta, Colette De Coster

We consider the resonant-superlinear elliptic problem−∆u=λ1u+(u+)q+f(x), withDirichlet boundary conditions on a bounded regular domain ofRN. We assume that 1<q<N+1N−1,f∈Ls(Ω) withs>Nsatisfies∫Ωfφ1<0 and (λ1,φ1) is the first eigenpair of−∆onH10(Ω). We apply a non-well ordered lower and…

A locking-free discontinuous Galerkin method for linear elasticity in locally nearly incompressible heterogeneous media

Daniele Antonio Di Pietro, Serge Nicaise

In this work we consider the problem of numerical locking in composite materials featuring quasi-incompressible and compressible sections. More specifically, we start by extending a classical regularity estimate for the $H^1$-norm of the divergence of the displacement field to the heterogeneous…
