Source identification for the wave equation on graphs, Identification de sources pour l'équation des ondes sur des graphes

Sergei Avdonin, Serge Nicaise

We consider source identification problems for the wave equation on an interval and on trees. The main advantage of our approach is its locality. Our algorithm reduces essentially to the resolution of a linear integral Volterra equation of the second kind and is new even for an interval., Nous considérons un problème d'identification de sources pour l'équation des ondes sur un intervalle ou sur des arbres. L'avantage principal de notre approche est sa localité. Notre algorithme se réduit essentiellement à la résolution d'une équation intégrale de Volterra du...

EXAMPLE BASED LEARNING FOR VIRTUAL PROTOTYPING ENGINEERING

Jean-Paul Becar, Mariana Fratu, Aurel Fratu, Jean-Charles Canonne

The paper deals with a method used many years for example based learning for the virtual prototyping. The authors collaborate since ten years in Erasmus background. It means four french students a year in the bachelor of technology course got a three months placement in Romania supervised by the...

Well-posedness and spectral properties of heat and wave equations with non-local conditions

Delio Mugnolo, Serge Nicaise

We consider the one-dimensional heat and wave equations but – instead of boundary conditions – we impose on the solution certain non-local, integral constraints. An appropriate Hilbert setting leads to an integration-by-parts formula in Sobolev spaces of negative order and eventually allows us to...

Classical and Relaxor Ferroelectric Behavior of Titanate of Barium and Zirconium Ceramics

Amina Tachafine, A. Aoujgal, Mohamed Rguiti, M.P.F. Graca, L.C. Costa, Abdelkader Outzourhit, Jean-Claude Carru

BaZrxTi1-xO3 (BZT) (x = 0 to 1) and BaZr0.05Ti0.95-y(Zn1/3Nb2/3)yO3 (BZT(ZnNb)) (y = 0 to 0.1) ceramics were prepared by the conventional solid-solid reaction method. The structural, ferroelectric and dielectric properties of BZT ceramics were studied as well as the dielectric properties of the BZT...

On Steinitz classes of nonabelian Galois extensions and p-ary cyclic Hamming codes

Maya Farhat, Bouchaïb Sodaïgui

Let k be a number field and Cl(k) its class group. Let Γ be a finite group. Let Rt(k,Γ) be the subset of Cl(k) consisting of those classes which are realizable as Steinitz classes of tamely ramified Galois extensions of k with Galois group isomorphic to Γ. Let p be a prime number. In the present...

Algebraic-trigonometric Pythagorean-hodograph curves and their use for Hermite interpolation

Lucia Romani, Laura Saini, Gudrun Albrecht

In this article we define a new class of Pythagorean-Hodograph curves built-upon a six-dimensional mixed algebraic-trigonometric space, we show their fundamental properties and compare them with their well-known quintic polynomial counterpart. A complex representation for these curves is introduced...
