La vague dans la matrice, The Wave in the Matrix

Gaëtan Robillard, Caterina Calgaro, Emmanuel Creusé

La Vague dans la matrice examine la relation entre mathématiques et environnement, en particulier la façon dont les sciences du climat inscrivent de nouveaux signes dans le monde. Le travail se matérialise dans un réseau de surfaces en cuivre et de processeurs qui simulent un champ de vagues généré...

Synthesis, crystal structure and magnetic behavior of a new calcium magnesium and iron orthophosphate Ca2MgFe2(PO4)4

Ahmed Ould Saleck, Cyrille Albert-Mercier, Claudine Follet-Houttemane, Olivier Mentré, Abderrazzak Assani, M. Saadi, L. El Ammari

The structure of the new calcium magnesium iron orthophosphate, Ca2MgFe2(PO4)4 was determined from single crystal X-ray diffraction data. It crystallizes in the orthorhombic system, space group Pbca, with all atoms in general positions among which two sites are disordered. The crystal structure of...

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...

Qualitative analysis of a curvature equation modeling MEMS with vertical loads

Chiara Corsato, Colette De Coster, Franco Obersnel, Pierpaolo Omari

We investigate existence, multiplicity and qualitative properties of the solutions of the Dirichlet problem for the singularly perturbed prescribed mean curvature equation - (1 - bu) div(\frac{\nabla u}{\sqrt{1 + |\nabla u|^2}}\Big) = frac{a}{(u-R)^2} +\frac{b}{\sqrt{1 + |\nabla u|^2}}, in \Omega,...

Nonexistence of Levi flat hypersurfaces with positive normal bundle in compact Kähler manifolds of dimension ≥3

Séverine Biard, Andrei Iordan

Let [Formula: see text] be a compact connected Kähler manifold of dimension [Formula: see text] and [Formula: see text] a [Formula: see text] Levi flat hypersurface in [Formula: see text]. Then the normal bundle to the Levi foliation does not admit a Hermitian metric with positive curvature along...

A combined finite volume - finite element scheme for a low-Mach system involving a Joule term

Caterina Calgaro, Claire Colin, Emmanuel Creusé

In this paper, we propose a combined finite volume-finite element scheme, for the resolution of a specific low-Mach model expressed in the velocity, pressure and temperature variables. The dynamic viscosity of the fluid is given by an explicit function of the temperature, leading to the presence of...

Development of Surface Acoustic Wave pressure sensors for monitoring concrete structures

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...

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...
