Points massiques, courbes de Bézier quadratiques et coniques : un état de l'art

Jean-Paul Becar, Lionel Garnier

Les courbes de Bézier quadratiques jouent un rôle fondamental pour la modélisation d'arc de coniques. L'utili-sation de points massiques permet de modéliser des demi-coniques dans le plan affine euclidien. A partir d'une courbe de Bézier de degré 2 donnée, il est possible de…, It is well known quadratic Bézier curves define conics. The use of massic points permits to define a semi-conic in the Euclidean plane. Moreover, from a given quadratic Bézier curve, we can determine the properties of the underlying conic. Moreover, the choice of an adequat non-degenerate…

Environmental Policy in a Dynamic Model with Heterogeneous Agents and Voting

Kirill Borissov, Thierry Bréchet, Stéphane Lambrecht

We consider a population of infinitely-lived households split into two: some agents have a high discount factor (the patients), and some others have a low one (the impatients). Polluting emissions due to economic activity harm environmental quality. The governmental policy consists in proposing…

Isotropic affine hypersurfaces of dimension 5

Olivier Birembaux, Luc Vrancken

We study affine hypersurfaces M which have isotropic difference tensor. Note that any surface always has isotropic difference tensor. Therefore, we may assume that n > 2. Such hypersurfaces have previously been studied by the first author and M. Djoric in [1] under the additional assumption that…

Ternary Zero Correlation Zone Sequence Sets for Asynchronous DS-CDMA

Benattou Fassi, Ali Djebbari, Abdelmalik Taleb-Ahmed

In this paper we propose a new class of ternary Zero Correlation Zone (ZCZ) sequence sets based on binary ZCZ sequence sets construction. It is shown that the proposed ternary ZCZ sequence sets can reach the upper bound on the ZCZ sequences. The performance of the proposed sequences set in…

On two optimal control problems for magnetic fields

Serge Nicaise, Simon Stingelin, Fredi Tröltzsch

Two optimal control problems for instationary magnetization processes are considered in 3D spatial domains that include electrically conducting and nonconducting regions. The magnetic fields are generated by induction coils. In the first model, the induction coil is considered as part of the…
