Multioutput Gaussian processes with functional data: A study on coastal flood hazard assessment

Andrés F. López-Lopera, Déborah Idier, Jeremy Rohmer, François Bachoc

Surrogate models are often used to replace costly-to-evaluate complex coastal codes to achieve substantial computational savings. In many of those models, the hydrometeorological forcing conditions (inputs) or flood events (outputs) are conveniently parameterized by scalar representations,…

Legendre Polynomial Modeling of a Piezoelectric Transformer

Derandraibe Jeannot Falimiaramanana, Hassna Khalfi, Joli Randrianarivelo, Faniry Emilson Ratolojanahary, Lahoucine Elmaimouni, I. Naciri, Mohamed Rguiti

A polynomial approach is used for solving wave propagation to forecast the performance of piezoelectric transformers (PTs). The method consists in integrating straightforwardly into the equation of motion via a delta function the continuity and boundary conditions. Resonance and anti-resonance…

Stability results for some hyperbolic systems with direct or indirect local dampings, Résultats de stabilité pour certains systèmes hyperboliques avec amortissements locaux directs ou indirects

Haidar Badawi

In this thesis, we study the indirect stability of some coupled systems with different kinds of local discontinuous dampings. We also study the stability and the instability results of the Kirchhoff plate equation with delay terms on the boundary or dynamical boundary controls. First, we…, Dans cette thèse, nous étudions la stabilité indirecte de certains systèmes couplés avec différents types d'amortissements locaux discontinus. Nous étudions également des résultats de stabilité et d'instabilité de l'équation des plaques de Kirchhoff avec des termes de retard à la…

Ceramic powder-based hybrid binder jetting system, Procédé hybride de fabrication additive par projection de liant sur lit de poudre céramique

Qirong Chen

Binder jetting (BJ) is an additive manufacturing process in which powders are selectively joined by a binder to reproduce an object layer by layer. Despite numerous advantages, BJ is still plagued by two main limitations. Ceramics printed with BJ remain very porous after sintering and exhibit poor…, Le Binder Jetting (BJ) ou projection de liant est un procédé de fabrication additive dans lequel des poudres sont sélectivement liées par un liant pour reproduire un objet couche par couche. Malgré ses nombreux avantages, le BJ souffre encore de deux limitations principales. Les céramiques…

On Levi flat hypersurfaces with transversely affine foliation

Séverine Biard, Masanori Adachi

We prove the non-existence of real analytic Levi flat hypersurface whose complement is 1-convex and Levi foliation is transversely affine in a compact Kähler surface.

Polydopamine treatment of chitosan nanofibers for the conception of osteoinductive scaffolds for bone reconstruction

Syrine Dimassi, Nicolas Tabary, Feng Chai, Cedric Zobrist, Jean-Christophe Hornez, Frederic Cazaux, Nicolas Blanchemain, Bernard Martel

We report the influence of treatment time of electrospun chitosan nanofibers (CHT NFs) in dopamine hydrochloride bath (2 mg.mL−1 in 10 mM Tris buffer, pH 8.5) on the extent of the polydopamine (pDA) coating on NFs surface. The reaction was characterized by FTIR and SEM analysis and the…

The influence of the physical coefficients of a Bresse system with one singular local viscous damping in the longitudinal displacement on its stabilization

Mohammad Akil, Haidar Badawi

In this paper, we investigate the stabilization of a linear Bresse system with one singular local frictional damping acting in the longitudinal displacement, under fully Dirichlet boundary conditions. First, we prove the strong stability of our system. Next, using a frequency domain approach…

The coupled heat Maxwell equations with temperature-dependent permittivity

Tonia-Maria Alam, Luc Paquet

We consider the heat equation coupled with the Maxwell system, the Ampère- Maxwell equation being coupled to the heat equation by the permittivity, which depends on the temperature due to thermal agitation, and the heat equation being coupled to the Maxwell system by the volumic heat source term.…
