Blind Channel Equalization Using Constrained Generalized Pattern Search Optimization and Reinitialization Strategy

Abdelouahib Zaouche, Iyad Dayoub, Jean-Michel Rouvaen, Charles Tatkeu

We propose a global convergence baud-spaced blind equalization method in this paper. This method is based on the application of both generalized pattern optimization and channel surfing reinitialization. The potentially used unimodal cost function relies on higher- order statistics, and its...

Thin chitosan films as a platform for SPR sensing of ferric ions

Holly A. Mcilwee, Caroline L. Schauer, Vera G. Praig, Rabah Boukherroub, Sabine Szunerits

Homogeneous chitosan films of various thicknesses (10–65 nm) were deposited on thin gold films through spin coating. The resulting interfaces were characterized using surface plasmon resonance (SPR), AFM, profilometry and cyclic voltammetry. The strong chelating properties of chitosan films to Fe...

Magnetically Actuated Microvalves for Active Flow Control

Olivier Ducloux, Yves Deblock, Abdelkrim Talbi, Leticia Gimeno, Nicolas Tiercelin, Philippe Pernod, Vladimir L. Preobrazhensky, Alain Merlen

This paper describes the design, fabrication and characterization of silicon based, high flow rate microvalves for the active control of separated air flows. The fabricated system provides pulsed microjets with an outlet speed reaching 150 m/s at an actuation frequency ranging from static actuation...

Directional beam pattern from a double metal quantum cascade laser with a TEM-horn antenna

Tahsin Akalin, Wilfried Maineult, Emilien Peytavit, P. Jellie, Jean-Francois Lampin, Carlo Sirtori, Stefano Barbieri

We present the operation and the far field radiation pattern of a 2.9 THz double metal quantum cascade laser (QCL) with a micro TEM-horn antenna. An improvement of both the radiation pattern and the collected power level (typically a factor of 2 with f/1 optics) are observed in comparison with the...

Enhanced directional optical transmission

L. Dobrzynski, Abdellatif Akjouj

The system presented here enables transmission of almost all the light intensities injected in four input channels into one output channel. It is conceived in the form of a metallic wire with one central hole and four other holes parallel to the central one. The incident light is injected in the...
