Effet de l'insertion d'un blindage électromagnétique sur la propagation des ondes de Lamb dans un composite à renforts de fibres de verre = Effect on the insertion of an electromagnetic shielding on the propagation of Lamb wave in GFRP

Dans cette étude, la propagation des ondes de Lamb dans deux matériaux composites, l'un à renforts de fibres de verre et l'autre composé de plis de verre avec une insertion d'un grillage métallique ont été étudiés. Comprendre les caractéristiques…

Spatio-temporal adaptive detector in non-homogeneous and low-rank clutter

Reducing the number of secondary data used to estimate the Clutter Covariance Matrix (CCM) for Space Time Adaptive Processing (STAP) techniques is still an active research topic. Low rank CCM estimates have already been proposed but only for…

Design of a 2.45 GHz rectenna using a global analysis technique

This paper presents the conception and the analysis of RF-DC conversion circuits at 2.45 GHz with microstrip line access, for a direct application on rectennas structures. To obtain accurate results, a global simulation which associate…

Dimensionnement de transformateurs intercellulaires pour un convertisseur flyback multicellulaire de forte puissance

The simplicity of the flyback converter is attractive but this topology is not used in high power converters because of the efficiency limitation due to the coupled inductor. This drawback can be eliminated in high power multicell flyback converters…

Comparative Study of Switched Reluctance Motors Performances for Two Current Distributions and Excitation Modes

This paper presents a 3-phase, 6-slot, and 4-pole Mutually Coupled Switched Reluctance Motor (MCSRM 6/4) with new current distribution. This kind of SRMs has both the merits of conventional SRMs and Fully Pitched SRMs, i.e. shorter end-windings and…

Comparison between Lead-Acid and Li-Ion Accumulators in Stand-Alone Photovoltaic System Using the Gross Energy Requirement Criteria

The high economic (and energetic) cost of storage accumulator system is still limiting the proliferation of SAPV system. Presently, due to its technical maturity and its low economical investment cost, the storage system universally used in SAPV…

Open-Loop Nash Strategy for Linear-Quadratic games via Matrix Pencil Approach

This paper deals with solving non-symmetric algebraic Riccati systems (NARS) and non-symmetric algebraic Riccati equations (NARE), from Nash strategy with an open-loop information structure applied on linear-quadratic games. A matrix pencil method…
