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...

Linear Multifractional Stable Motion: fine path properties

Antoine Ayache, Julien Hamonier

Linear Multifractional Stable Motion (LMSM), denoted by $\{Y(t):t\in\R\}$, has been introduced by Stoev and Taqqu in 2004-2005, by substituting to the constant Hurst parameter of a classical Linear Fractional Stable Motion (LFSM), a deterministic function $H(\cdot)$ depending on the time variable $...

Classes de Steinitz dʼextensions galoisiennes à groupe de Galois de centre non trivial

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. R m(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...

On Some Holomorphic Cohomological Equations

Aziz El Kacimi Alaoui

Let Σ be a non compact Riemann surface and γ:Σ⟶Σ an automorphism acting freely and properly such that the quotient M = Σ/γ is a non compact Riemann surface. Using the fact that Σ and M are Stein manifolds, we prove that, for any holomorphic function g:Σ⟶C and any λ∈C , there exists a holomorphic...
