Optimal control of some quasilinear Maxwell equations of parabolic type

Serge Nicaise, Fredi Tröltzsch

An optimal control problem is studied for a quasilinear Maxwell equation of nondegenerate parabolic type. Well-posedness of the quasilinear state equation, existence of an optimal control, and weak Gâteaux-different-iability of the control-to-state mapping are proved. Based on these results, first-…

From homotopy perturbation technique to reduced order model for multiparametric modal analysis of large finite element models

Franck Massa, Isabelle Massa-Turpin, Thierry Tison

The paper focuses on the definition of a reduced order model for linear modal analysis. The aim is to supply a suitable mathematical alternative tool compatible for multiparametric analysis of large finite element model considering numerous variable parameters, numerous mode shapes and significant…

Four-dimensional contact CR-submanifolds in S7(1)

Mirjana Djorić, Marian Ioan Munteanu, Luc Vrancken

The analogue of CR -submanifolds in (almost) Kählerian manifolds is the concept of contact CR -submanifolds in Sasakian manifolds. These are submanifolds for which the structure vector field ξ is tangent to the submanifold and for which the tangent bundle of M can be decomposed as T(M)=H(M)⊕E(M)⊕Rξ…

Usage des points massiques et des courbes de Bézier pour la modélisation des cubiques

Karine Serier, Jean-Paul Becar, Lionel Garnier

Cet article étend l'étude des points singuliers et des points d'inflexion des courbes rationnelles cubiques en s'ins-pirant de la méthode proposée par M. Sakai dans le cadre des points massiques. L'intérêt des points massiques est de généraliser le tracé des courbes admettant…

Planar Pythagorean-Hodograph B-Spline curves

Gudrun Albrecht, Carolina Vittoria Beccari, Jean-Charles Canonne, Lucia Romani

We introduce a new class of planar Pythagorean-Hodograph (PH) B-Spline curves. They can be seen as a generalization of the well-known class of planar Pythagorean-Hodograph (PH) Bézier curves, presented by R. Farouki and T. Sakkalis in 1990, including the latter ones as special cases. Pythagorean-…

Synthèse de dioxyde de titane déposé sur des supports macro-poreux SiBC et SiBCN pour la photo-catalyse, Synthesis of titanium dioxide coated on macroporous SiCB and SiBCN supports for photocatalysis

Mélanie Wynn

La photo-catalyse est une voie très prisée pour la dépollution de l’eau ou de l’air. Le photo-catalyseur le plus employé est le dioxyde de titane (TiO2) mais l’activité photo-catalytique peut fortement varier d’une poudre à l’autre. De plus, il est très avantageux, voire nécessaire, de le déposer…, Photocatalysis is a method of choice for water and air depollution. Titanium dioxide (TiO2) is the most used photocatalyst but photocatalytic activity can widely differ from one powder to another. Moreover, it is useful, or even necessary, to immobilize it on a support; in particular, a porous…
