Characterization of the generalized Calabi composition of affine hyperspheres

M. Antic, Z. Hu, C. C. Li, Luc Vrancken

In this paper, continuing with Hu-Li-Vrancken and the recent work of Antie-Dillen-Schoels Vrancken, we obtain a decomposition theorem which settled the problem of how to determine whether a given locally strongly convex affine hypersurface can be decomposed as a generalized Calabi composition of…

Développement de capteurs interdigités pour le contrôle de structures

Rafatou Takpara, Dame Fall, Marc Duquennoy, Mohammadi Ouaftouh, Christian Courtois, Mohamed Rguiti, M. Gonon, N. Maurye, Gregory Martic, Véronique Lardot, Laurent Seronveaux, J. Halleux, Christine Pelegris, Mohamed Guessasma

Ce travail porte sur la réalisation de capteurs interdigités (IDT) afin de caractériser la qualité des revêtements et les surfaces des structures. L’enjeu de cette étude est triple. Il s'agit premièrement de disposer de capteurs efficaces pour générer des ondes acoustiques de surface SAW (…

The multidimensional wave equation with generalized acoustic boundary conditions I: Strong stability

Zainab Abbas, Serge Nicaise

We study the wave equation on a domain of ℝd, d ≥ 2, with dynamical boundary control applied on a part of the boundary and a Dirichlet boundary condition on the remaining part. We prove the asymptotic stability and nonuniform stability of the associated semigroup.

Three-Dimensional Minimal CR Submanifolds of the Sphere S 6 (1) Contained in a Hyperplane

Miroslava Antić, Luc Vrancken

It is well known that the sphere S6(1) admits an almost complex structure J, constructed using the Cayley algebra, which is nearly Kähler. Let M be a Riemannian submanifold of a manifold (Formula Presented.) with an almost complex structure J. It is called a CR submanifold in the sense of Bejancu (…

Space-time residual-based a posteriori estimator for the A-phi formulation in eddy current problems

Roberta Tittarelli, Yvonnick Le Menach, Emmanuel Creusé, Serge Nicaise, Francis Piriou, Olivier Moreau, Olivier Boiteau

In this paper, an a posteriori residual error estimator is presented for the 3-D eddy current problem modeled by the space-time A - φ potential formulation. It is solved by the finite element method in space and the backward Euler scheme in time. Once the reliability as well as the efficiency of…

Source identification for the wave equation on graphs

Sergei Avdonin, Serge Nicaise

We consider source identification problems for the wave equation on graphs. The main advantage of our approach is its locality. Our algorithm reduces essentially to the resolution of linear integral Volterra equations of the second kind and is new even for an interval.

Thermal conductivity modeling of Alumina/Al functionally graded composites

Christine Pelegris, Nabil Ferguen, Willy Leclerc, Yannick Lorgouilloux, Stéphane Hocquet, Olivier Rigo, Mohamed Guessasma, Emmanuel Bellenger, Christian Courtois, Véronique Lardot, Anne Leriche

This paper describes a new manufacturing process for producing functionally graded ceramic‐metal composites with anisotropic properties for thermal management in automotive engine blocks. These composites are elaborated by producing a porosity gradient within an alumina matrix, subsequently…
