Convergence analysis of an hp finite element method for singularly perturbed transmission problems in smooth domains

Serge Nicaise, Xenophontos Christos

We consider a two-dimensional singularly perturbed transmission problem with two different diffusion coefficients, in a domain with smooth (analytic) boundary. The solution will contain boundary layers only in the part of the domain where the diffusion coefficient is high and interface layers along...

Elaboration and characterization of a low frequency and wideband piezoceramic generator for energy harvesting

Mohamed Rguiti, A. Hajjaji, Sophie d'Astorg, Christian Courtois, Anne Leriche

The aim of this work was to efficiently convert the mechanical vibrations into electrical energy by using direct piezoelectric effect. Most mechanical vibrations occur at low frequencies varying from 50 to 120 Hz. As piezoelectric converters provide maximum energy conversion when their natural...

Regularity results for elliptic problems with measure

Sadjiya Ariche, Colette De Coster, Serge Nicaise

In this work, we study the solution of the Laplace equation: \[ -\Delta u =g \delta_\sigma\;\;\;\hbox{ in } Q\subseteq \mathbb{R}^3, \] where \(\delta_\sigma\) is the Dirac mass on a crack \(\sigma\) of \(Q\) and \(g\in L^2(\sigma)\). First, we discuss the existence and the uniqueness of a solution...

Geometric modeling of thick and closed surfaces : application to pelvic organs

Thierry Bay

Although surgery is often used to treat disorders coming from physiological changes in the spatial configuration of the pelvic organs, the process is poorly reproductible and controllable from one patient to another. The work described below consists in developping a realistic geometric modeling,...

A posteriori error estimator for harmonic A‐φ formulation

Zuqi Tang, Yvonnick Le Menach, Emmanuel Creusé, Serge Nicaise, Francis Piriou, Nicolas Nemitz

Purpose - In this paper, the aim is to propose a residual-based error estimator to evaluate the numerical error induced by the computation of the electromagnetic systems using a finite element method in the case of the harmonic A-? formulation. Design/methodology/approach - The residual based error...

Reflection Equation Algebra and its applications to Noncommutative Geometry

Dimitri Gurevich

Reflection Equation Algebra (REA) is one of the central objects of Braided Geometry. By Braided Geometry I mean a theory related to a braiding, i.e. a solution to the Quantum Yang-Baxter Equation. I’ll exhibit properties of the REA related to different types of braidings. Also, I’ll explain the...
