A Block Turbo Phase Synchronization Scheme

This letter presents an original phase synchronization scheme designed for block turbo coded systems. This is a low-complexity scheme. It copes with low signal-to-noise ratios, taking complete advantage of the turbo coding possibilities. We display…

Fiabilité des composants de puissance dans des environnements hautes températures

La thématique de recherche abordée dans cet article est motivée par l'utilisation croissante de l'électricité dans le domaine des transports, avec la recherche d'une réduction de la consommation d'énergie et de l'émission des gaz polluants. Cette…

Surface and aerodynamic roughness in arid and semiarid areas andtheir relation to radar backscatter coefficient

Surface roughness is a key parameter for surface-atmosphere exchanges of mass andenergy. Only a few field measurements have been performed in arid or semiarid areaswhere it is an important control of the aeolian erosion threshold. An intensive…

Eddy current imager for the detection of buried flaws in large metallic structures

The authors present a prototype of an eddy current imager dedicated to the high speed inspection of aeronautic riveted lap joints. The system provides high resolution images of the complex magnetic field distribution at the surface of the inspected…

A Stackelberg Game Approach to Mixed $H_2/H_\infty$ Control

The $H_2/H_\infty$ robust control problem is formulated as a Stackelberg differential game where the leader minimizes an $H_2$criterion while the follower deals with the $H_\infty$ constraint. For a closed loop information structure in the game, the…

A modular approach to two-photon absorbing organic nanodots: brilliant dendrimers as an alternative to semiconductor quantum dots?

Nanoscopic fluorescent dendrimers having up to 96 two-photon chromophores and showing giant two-photon absorption crosssections (up to 56 000 GM) were designed as a complementary "organic" alternative to quantum dots.

Nanoneedle fields for biological interaction with cells

In this paper a new nanostructured support for the culture of cells is presented. The support is constituted of fields of shar p and high-aspect ratio nanoneedles. The support is obtained through a specifically developed process that allows…
