Stabilization of some coupled systems involving (thermo-) viscoelastic/elastic transmission problems or telegraph equations in bounded domains or in networks, Stabilisation de quelques systèmes couplés impliquant problèmes de transmission (thermo-) viscoélastiques/élastiques ou équations télégraphiques dans des domaines bornés ou sur réseaux

Alaa Hayek

This thesis is concerned with the stabilization of some coupled systems that involves (thermo-) viscoelastic/elastic transmission problems and telegraph equations in bounded domains or in networks. First, we consider the stability of a system of weakly coupled wave equations with one or two local..., Cette thèse s’intéresse a la stabilisation de certains systèmes couples impliquant des problèmes de transmission (thermo-) viscoélastique/élastique et des équations télégraphiques dans des domaines bornes ou sur réseaux. Dans un premier temps, nous considérons la stabilité d’un système d’équations...

Four dimensional biharmonic hypersurfaces in nonzero space forms have constant mean curvature

Zhida Guan, Haizhong Li, Luc Vrancken

In this paper, through making careful analysis of Gauss and Codazzi equations, we prove that four dimensional biharmonic hypersurfaces in nonzero space forms have constant mean curvature. Our result gives the positive answer to the conjecture proposed by Balmuş–Montaldo–Oniciuc in 2008 for four...

Bone-like ceramic scaffolds designed with bioinspired porosity induce a different stem cell response

Silvia Panseri, Monica Montesi, Dominique Hautcoeur, Samuele Dozio, Shaan Chamary, Eamonn de Barra, Anna Tampieri, Anne Leriche

Abstract Biomaterial science increasingly seeks more biomimetic scaffolds that functionally augment the native bone tissue. In this paper, a new concept of a structural scaffold design is presented where the physiological multi-scale architecture is fully incorporated in a single-scaffold solution...

Experimental and Numerical Investigations for Quantifying Variability of NR Mechanical Properties after Thermal Aging

Andrés Malo Estepa, Franck Massa, Adnane Boukamel, Thierry Tison, Philippe Champagne, Stéphane Méo, Andreas Wolf

The evolution of mechanical properties of NR with carbon black fillers was examined after a thermal aging step through both experimentation and non-deterministic numerical simulations. A quantification of mechanical properties and associated variability is first proposed for a set of specimens...

Under pressure! Nudging electricity consumption within firms. Feedback from a field experiment

Christophe Charlier, Gilles Guerassimoff, Ankinée Kirakozian, Sandrine Selosse

Many economists and psychologists have studied the impact of nudges on households' pro-environmental behaviors. Interestingly, "private nudges'' can be imagined for companies. Yet, studies focusing on nudging employees' energy use are rare. The objective of our paper is to...

Every centroaffine Tchebychev hyperovaloid is ellipsoid

Xiuxiu Cheng, Zejun Hu, Luc Vrancken

We study locally strongly convex Tchebychev hypersurfaces, namely the centroaffine totally umbilical hypersurfaces, in the (n+1)-dimensional affine space Rn+1. We first make an ordinary-looking observation that such hypersurfaces are characterized by having a Riemannian structure admitting a...

Adaptation in a heterogeneous environment. I: Persistence versus extinction

François Hamel, Florian Lavigne, Lionel Roques

Understanding how a diversity of plants in agroecosystems affects the adaptation of pathogens is a key issue in agroecology. We analyze PDE systems describing the dynamics of adaptation of two phenotypically structured populations, under the effects of mutation, selection and migration in a two-...
