Surface canal, squelette et espace des sphères

Jean-Paul Becar, Sylvie Chambon, Bastien Durix, Lionel Garnier, Géraldine Morin, Céline Roudet

Une surface canal est l'enveloppe d'une famille à un paramètre de sphères orientées. Connaissant les fonctions de centre et de rayon associées à celle-ci, il est aisé d'obtenir une paramétrisation de la surface. Nous étudions dans cet article l'opération inverse, c'est-à-..., A canal surface is the envelope of a one-parameter familly of oriented spheres. With the knowledge of center an radius functions associated to it, it is easy to compute a parametrisation of the surface. In this article, we study the inverse operation, which is the search for the spheres in the...

The Dirichlet problem for a prescribed anisotropic mean curvature equation

Chiara Corsato, Colette De Coster, Pierpaolo Omari

We discuss existence, uniqueness, regularity and boundary behaviour of solutions of the Dirichlet problem for the prescribed anisotropic mean curvature equation −div(∇u/1+|∇u|2)=−au+b/1+|∇u|2, where a,b>0 are given parameters and Ω is a bounded Lipschitz domain in RN. This equation appears in...

Development of flexible SAW sensors for non-destructive testing of structure

Rafatou Takpara, Marc Duquennoy, Christian Courtois, Maurice Gonon, Mohammadi Ouaftouh, Gregory Martic, Mohamed Rguiti, Frédéric Jenot, Laurent Seronveaux, Christine Pelegris

In order to accurately examine structures surfaces, it is interesting to use surface SAW (Surface Acoustic Wave). Such waves are well suited for example to detect early emerging cracks or to test the quality of a coating. In addition, when coatings are thin or when emergent cracks are precocious,...

Curvature properties of some class of warped product manifolds

Ryszard Deszcz, Małgorzata Głogowska, Jan Jełowicki, Georges Zafindratafa

We prove that warped product manifolds with p-dimensional base, p=1,2, satisfy some pseudosymmetry type curvature conditions. These conditions are formed from the metric tensor g, the Riemann–Christoffel curvature tensor R, the Ricci tensor S and the Weyl conformal curvature C of the considered...

Design of C2 algebraic-trigonometric pythagorean hodograph splines with shape parameters

Cindy González, Gudrun Albrecht, Marco Paluszny, Marianela Lentini

In this paper, we construct C2 Algebraic-Trigonometric Pythagorean Hodograph (ATPH) splines by solving a non-linear system of equations in complex variables. We compare these splines, which depend on several shape parameters, with their polynomial PH counterpart as well as with the well-known C2...

Predictive models of the energy consumption in intelligent buildings

M Fratu, Jean-Paul Becar, Jean-Charles Canonne

In this work we present a novel approach to energy saving in buildings through the identification of the relevant parameters and the application of Soft Computing techniques to generate predictive models of energy consumption in buildings. To verify the feasibility of this proposal, we apply our...

Piezoelectric composites of PU/PZT with 0–3 connectivity were prepared in the film form. Homogeneous dispersion of the ceramic PZT in polyurethane matrix has been obtained and has been verified by SEM analysis. Dielectric properties reveal that under an electrical field of 1000 V the remnant...
