Non-efficacité et non-gaussianité asymptotiques d'un estimateur du maximum de vraisemblance à fort rapport signal sur bruit

En théorie de l'estimation, dans le cas d'observations indépendantes de mêmes densités de probabilité, l'efficacité asymptotique en le nombre T d'observations de la méthode du Maximum de Vraisemblance (MV) est un résultat bien connu qui permet d…

Le redresseur MLI en absorption sinusoïdale de courant

Les convertisseurs à découpage, fonctionnant en absorption sinusoïdale de courant, restent assez peu traités dans notre littérature bien qu'avec l'évolution des normes sur la pollution harmonique, ceux-ci soient amenés à se généraliser. Cet article…

Optimization Material Distribution in Electromagnetic Actuators

In this paper, a new approach for Optimization Material Distribution is proposed. The principle behind this approach is to use a surface genetic algorithm in order to determine material distribution in a fixed Finite Element Computation mesh. The…

3D Modeling of a Magneto-Optic Imager by a Dyadic Green’s Functions Approach

A 3D semi‐analytical model based on dyadic Green’s functions is proposed to solve the forward problem for a magneto‐optic imager with a simplified eddy‐current excitation. The normal component of the magnetic field is evaluated in place of the…

Magnetic properties of nanocomposites containing Fe-Ni or Fe dispersed in a Mn-Zn ferrite matrix

Composites have been prepared from Mn-Zn and Fe or Fe/sub 25/Ni/sub 75/ nanostructured powders, by melting in a planetary mill, compaction, and subsequent annealing. A solid state oxido-reduction reaction between iron and ferrite degrades the…

Conception, modélisation et optimisation des actionneurs polyentrefers à bobinages globaux : Application aux structures linéaires multi-tiges

The aim of this thesis is the study and the conception of splited structures of global coil synchronous machines for the maximisation of specific torque or thrust. This concept of machine, called multi-airgap, is more precisely applied to the…
