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...

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,...

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...

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...

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...

Uniform a priori estimates for elliptic problems with impedance boundary conditions

Théophile Chaumont-Frelet, Serge Nicaise, Jérôme Tomezyk

We derive stability estimates in H2 for elliptic problems with impedance boundary conditions that are uniform with respect to the impedance coefficient. Such estimates are of importance to establish sharp error estimates for finite element discretizations of contact impedance and high-frequency...

Spark Plasma Sintering and tribological behavior of Ti3SiC2–Ti5Si3–TiC composites

Abdessabour Benamor, Youcef Hadji, Nabil Chiker, Adel Haddad, Bendiba Guedouar, Mohamed Labaiz, Maamar Hakem, Arnaud Tricoteaux, Christelle Nivot, Jean-Pierre Erauw, Riad Badji, Mohamed Hadji

Herein, we study the effect of TiC content on the tribological behavior of four Ti3SiC2/Ti5Si3/TiC composites, prepared through Spark Plasma Sintering. The tribological properties were investigated under dry sliding, against Al2O3 counterpart at room temperature, under different normal loads and...

Nanotechnology to improve the performances of hydrodynamic surfaces

Ali Ahmed Alshehri, Philippe Champagne, Laurent Keirsbulck, El Hadj Dogheche

ure continues to inspire scientists to adapt solutions in order to satisfy human needs, mainly in the maritime domain with metallic surface corrosion and its mechanical friction. In this research, the source of innovation comes from the lotus leaf and its well-known super-hydrophobicity. In this...
