Collision Times of Random Walks and Applications to the Brownian Web

David Coupier, Kumarjit Saha, Anish Sarkar, Viet Chi Tran

Convergence of directed forests, spanning on random subsets of lattices or on point processes, towards the Brownian web has made the subject of an abundant literature, a large part of which relies on a criterion proposed by Fontes, Isopi, Newman and Ravishankar (2004). One of their convergence...

Characterization and extensive study of cubic and quintic algebraic trigonometric planar PH curves, Caractérisation et étude approfondie des courbes planes algébriques-trigonométriques à hodographe pythagorien

Isabelle Cattiaux-Huillard, Laura Saini

This paper deals with Pythagorean hodograph curves of the spaces of algebraic trigonometric functions and trigonometric polynomials, span {1, t, {cos (kt) , sin (kt)}k=1^m and span {1, {cos (kt) , sin (kt)}k=1^m , respectively. First, we propose a general characterization of planar PH curves in...

Sintering of BaTiO3 powder/sol composite thick films and their dielectric and piezoelectric properties

Jean-François Trelcat, Natanaël Basile, Maurice Gonon, Mohamed Rguiti, Christian Courtois, Anne Leriche

In this work, barium titanate thick films are produced at low-temperature using a modified sol–gel/ceramic powder technology named the composite route. In this process, a commercial BaTiO3 powder, doped or not by Li2O as sintering aid, is mixed with a stabilized titanium (IV) isopropoxide/barium...

Développement de capteurs interdigités à ondes acoustiques de surface pour l'estimation de l'humidité dans des structures en béton, Development of surface acoustic wave interdigitated sensors for humidity estimation in concrete structures

Saliou Ndao

Dans ce travail, nous avons développé des capteurs ultrasonores interdigités (IDT) d’humidité exploitant des ondes acoustiques de surface (SAW) de type Rayleigh. Ces capteurs SAWIDT sont destinés à suivre d’une part l’humidité ambiante dans les bétons du génie civil et d’autre part, le monitoring..., In this work, we have developed ultrasonic humidity interdigital (IDT) sensors exploiting Rayleigh type Surface Acoustic Waves (SAW). These SAW-IDT sensors are intended to monitor ambient humidity in civil engineering concretes and to monitor the refractory concretes drying at high temperatures (up...

Weighted-$L^2$ polynomial approximation in $\mathbb {C}$

Séverine Biard, John Erik Fornæss, Jujie Wu

We study the density of polynomials in H2(Ω, e−φ), the space of square integrable holomorphic functions in a bounded domain Ω in C, where φ is a subharmonic function. In particular, we prove that the density holds in Carath´eodory domains for any subharmonic function φ in a neighborhood of Ω. In...

A finite volume method for a convection- diffusion equation involving a Joule term

Caterina Calgaro, Emmanuel Creusé

This work is devoted to a Finite Volume method to approximate the solution of a convection-diffusion equation involving a Joule term. We propose a way 5 to discretize this so-called "Joule effect" term in a consistent way with the non linear diffusion one, in order to ensure some maximum...

Hassan Alhousseini, Marc Duquennoy, Christian Courtois, Mohammadi Ouaftouh, Nikolay Smagin, Frédéric Rivart, Marc Poorteman, Maurice Gonon, Gregory Matric, Mohamed Rguiti, Christine Peligris

For many years surface acoustic waves (SAW) have been used in manufacturing electronic components for industrial and sensing applications. Due to the absence of an embedded electronic system and the possibility of wireless communication this technology can offer a great solution for sensing in...

Mechanical properties of thermally sprayed porous alumina coating by Vickers and Knoop indentation

Ghailen Ben Ghorbal, Arnaud Tricoteaux, Anthony Thuault, H. Ageorges, F. Roudet, D. Chicot

Depending on the thermal spraying conditions, coatings obtained can present different defects, like pores, cracks and/or unmelted particles, and different surface roughnesses, that can affect the determination of the hardness and elastic modulus. The present work investigates the mechanical...
