Development of a dual temporal-spatial chirp method for the generation of broadband surface acoustic waves

Marc Duquennoy, Dame Fall, Mohammadi Ouaftouh, Farouk Benmeddour, Salah-Eddine Hebaz, Nikolay Smagin, Bogdan Piwakowski, Frédéric Jenot

This study deals with the optimization of transducers for Rayleigh-type Surface Acoustic Waves (SAW) generation. These transducers are based on Interdigital Transducers (IDT) and are specifically developed to characterize properties of thin layers, coatings, and functional surfaces. In order to…

Computation of dispersion curves of guided waves using discontinuous Galerkin finite element method: Application to functionally graded materials

Salah-Eddine Hebaz, Farouk Benmeddour, Emmanuel Moulin, Jamal Assaad, Marc Duquennoy, Mohammadi Ouaftouh

The study of dispersive behavior of guided waves is of great interest in non-destructive testing and development of inspection systems. In this work, a semi-analytical numerical formulation for the computation of dispersion curves and mode shapes in plate-like structures is presented. The…

Eigen frequencies and directivity patterns of a spherical acoustic transducer

Daher Diab, Fabrice Lefebvre, Georges Nassar, Nikolay Smagin, Adnan Naja, Fawaz El Omar

In this work, a spherical acoustic sensor has been developed, and is composed of two Plexiglas half-spheres and a PZ26 piezoelectric ring that can be either used as an exciter or as a sensor. The resonance of the spherical shell is studied analytically, numerically by finite elements modeling in…

Designing a camera placement assistance system for human motion capture based on a guided genetic algorithm

Azeddine Aissaoui, Abdelkrim Ouafi, Philippe Pudlo, Christophe Gillet, Zine-Eddine Baarir, Abdelmalik Taleb-Ahmed

In multi-camera motion capture systems, determining the optimal camera configuration (camera positions and orientations) is still an unresolved problem. At present, configurations are primarily guided by a human operator’s intuition, which requires expertise and experience, especially with complex…

Rapid in-memory matrix multiplication using associative processor

Mohamed Ayoub Neggaz, Hasan Erdem Yantir, Smail Niar, Fadi Kurdahi, Ahmed Eltawil

Memory hierarchy latency is one of the main problems that prevents processors from achieving high performance. To eliminate the need of loading/storing large sets of data, Resistive Associative Processors (ReAP) have been proposed as a solution to the von Neumann bottleneck. In ReAPs, logic and…

L'Ecosse sous Theresa May: résurgence des enjeux constitutionnels en réaction au Brexit

Edwige Camp-Pietrain

Le référendum sur le Brexit a provoqué la résurgence des enjeux constitutionnels en Écosse, en trois étapes distinctes jusqu’à la fin de l’année 2017. Nicola Sturgeon, forte du soutien de la majorité des électeurs et des élus écossais, a tout d’abord tenté de proposer l’adhésion à l’EEE afin de…

Flat almost complex surfaces in the nearly Kähler S3 × S3

Luc Vrancken

In this talk we show how to study almost complex submanifolds of S3 × S3. Compact 6-dimensional non-K¨ahler nearly K¨ahler manifolds do not admit 4-dimensional almost complex submanifolds, so the almost complex submanifolds are surfaces. Previously, a classification of the totally geodesic almost…

On Convective Heat Transfer and Flow Dynamics Through a Straight T-Bifurcating Channel

Abdelhak Lakehal, Nora Nait Bouda, Julien Pellé, Souad Harmand

Both experimental and numerical studies of a turbulent flow in a bifurcating channel are performed to characterize the dynamical behavior of the flow and its impact on the convective heat transfer on the sides of the branch. This configuration corresponds to the radial vents placed in the stator…

Speaker Identification Based On Vocal Cords Vibrations signal: Effect Of The Window

Dany Ishac, Antoine Abche, Elie Karam, Georges Nassar, Dorothée Debavelaere-Callens

A new speaker identification technique was proposed and presented. It is based on the acquisition of the individual’s signal of its vocal cords’ vibrations by attaching a piezoelectric transducer element to a collar and wrapping it around the neck. Having collected the signal, the Short Term…
