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…

Braided algebras and their applications to Noncommutative Geometry

Dimitri Gurevich, Pavel Saponov

We introduce the notion of a braided algebra and study some examples of these. In particular, R-symmetric and R-skew-symmetric algebras of a linear space V equipped with a skew-invertible Hecke symmetry R are braided algebras. We prove the “mountain property” for the numerators and denominators of…

Processing and properties of biphasic calcium phosphates bioceramics obtained by pressureless sintering and hot isostatic pressing

Michel Descamps, Laurent Boilet, Gérard Moreau, Arnaud Tricoteaux, Jianxi Lu, Anne Leriche, Véronique Lardot, Francis Cambier

Calcium phosphate powders were obtained from coprecipitation method using diammonium phosphate and calcium nitrate solutions. The adjustment of experimental parameters and Ca/P initial ratio allowed synthesizing stoichiometric HA and β-TCP powders and four biphasic calcium phosphates (BCP) with…

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…

New tools for animation and design : a haptic-based system for stop motion camera animation and curve design by algebraic-trigonometric Pythagorean Hodograph curves, Nouveaux outils pour l'animation et le design : système d'animation de caméra pour la stop motion, fondée sur une interface haptique et design de courbes par des courbes algébriques-trigonométriques à hodographe pythagorien

Laura Saini

In the first part, we present a new system that allows to create realistic cameramovements for a stop motion animation. The system improves traditional 3D software animation programs (for example Maya and 3D Studio Max) for creatingstop motion camera movements by using an haptic interface. After…, Dans la première partie de la thèse, nous présentons un nouveau système permettant de produire des mouvements de caméra réalistes pour l’animation stopmotion. Le système permettra d’enrichir les logiciels d’animation 3D classiques (comme par exemple Maya et 3D Studio Max) afin de leur faire…
