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...

Classes de Steinitz d'extensions galoisiennes à groupe de Galois un 2-groupe

Bouchaïb Sodaïgui

Let k be a number field and Cl(k) its class group. Let Γ be a finite group and |Γ | its order. Let R(k,Γ) (resp. Rm(k,Γ)) be the subset of Cl(k) consisting of those classes which are realizable as Steinitz classes of Galois extensions (resp. tamely ramified Galois extensions) of k with Galois group..., Soient k un corps de nombres et Cl(k) son groupe de classes. Soient Γ un groupe fini et |Γ | son ordre. Soit R(k,Γ) (resp.Rm(k,Γ)) le sous-ensemble de Cl(k) formé par les éléments qui sont réalisables par les classes de Steinitz d’extensions galoisiennes (resp. galoisiennes et modérément ramifiées...

Cohomologie de Dolbeault feuilletée de certaines laminations complexes, Cohomology of some complex laminations

Rochdi Ben Charrada

Dans cette thèse, nous nous s’intéressons au calcul des groupes de cohomologie de Dolbeault feuilletée H0∗L (M) de certaines laminations complexes. Ceci revient à résoudre le problème du ∂ le long des feuilles ∂Lα = ω. (Ici M est un espace métrique ou une variété dans le cas où L est un feuilletage..., In this thesis, we are interested in computing the foliated Dolbeault cohomology groups H0∗L (M) for some complex laminations. This amounts to solving the problem of the ∂ along the leaves ∂Lα = ω. (Here M is a metric space or a differentiable manifold if L is a foliation F.) Three situations were...

Stabilization and approximation of some distributed systems by either dissipative or inde, Stabilisation et approximation de certains systèmes distribués par amortissement dissipatif et de signe indéfini

Farah Abdallah

In this thesis, we study the approximation and stabilization of some evolution equations, using semigroup theory and some spectral analysis. This Ph.D. thesis is divided into two main parts. In the first part, as in [3, 4], we consider the approximation of second order evolution equations modeling..., Dans cette thèse, nous étudions l'approximation et la stabilisation de certaines équations d'évolution, en utilisant la théorie des semi-groups et l'analyse spectrale. Cette thèse est divisée en deux parties principales. Dans la première partie, comme dans [3, 4], nous considérons l...

Algebraic functor calculus and commutator theory

Manfred Hartl

Classically, Lie algebras can be considered as linearizations of groups in several ways, and thus provide key tools in group theory. With the emergence of more and more other non-linear algebraic structures the problem arises to generalize the relations between groups and Lie algebras to a much...

Residual Based a Posteriori Error Estimators for Harmonic A/φ and T/Ω Formulations in Eddy Current Problems

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

For eddy current problems, potential formulations are widely used nowadays. In this paper, residual based a posteriori error estimators are introduced to evaluate the discretization error in the finite element calculation in both case of A /φ and T /Ω harmonic formulations. A device with eddy...

Development of superhydrophilic and superhydrophobic polyester fabric by growing Zinc Oxide nanorods

Anne Perwuelz, Munir Ashraf, Christine Campagne, Philippe Champagne, Anne Leriche, Christian Courtois

ZnO nanorods were grown on microfibers of Polyethylene terephthalate (PET) fabric by seeding method to develop hierarchical roughness structure. XRD and XPS analysis show the presence of crystalline ZnO and chemical Zn species at the fiber surface at each stage of the process. Five series of...

On actions and strict actions in homological categories

Manfred Hartl, Bruno Loiseau

Let $G$ be an object of a finitely cocomplete homological category $\mathbb C$. We study actions of $G$ on objects $A$ of $\mathbb C$ (defined by Bourn and Janelidze as being algebras over a certain monad $\mathbb T_G$), with two objectives: investigating to which extent actions can be described in...

Approximation of the two-dimensional Dirichlet problem by one-dimensional continuous and discrete problems on one-dimensional networks

Maryse Bourlard-Jospin, Serge Nicaise, Juliette Venel

We show that the solution of the two-dimensional Dirichlet problem set in a plane domain is the limit of the solutions of similar problems set on a sequence of one-dimensional networks as their size goes to zero. Roughly speaking this means that a membrane can be seen as the limit of rackets made...
