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…

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…

Arrayed Micro Needles for Mechanical Gene Insertion

A novel approach to realize arrays of out of plane micro needles is given. The exterior shape of the micro needles is realized by dry etching using a RIE. The exterior shape is realized in silicon by dry etching using a SF6 and Argon plasma that…

Nanometer Scale Patterning of Langmuir−Blodgett Films of Gold Nanoparticles by Electron Beam Lithography

Electron beam lithography on Langmuir−Blodgett films of alkanethiol-capped gold nanoparticles is shown to be a viable strategy to define nanometer scale structures of such particles. Sub-50 nm wide “nanowires”, the thickness of which is controlled…
