Fusing transformed deep and shallow features (FTDS) for image-based facial expression recognition

Fares Bougourzi, Fadi Dornaika, K. Mokrani, Abdelmalik Taleb-Ahmed, Yassine Ruichek

In this paper, we propose combining between the transformed hand-crafted and deep features using PCA to recognize the six-basic facial expressions from static images. To evaluate our approach, we use three popular databases (CK+, CASIA and MMI). We introduce the use of the Pyramid Multi Level (PML…

Properties of nanocrystalline silicon probed by optomechanics

Daniel Navarro-Urrios, Martín F Colombano, Jeremie Maire, Emigdio Chávez-Ángel, Guillermo Arregui, Néstor E Capuj, Arnaud Devos, Amadeu Griol, Laurent Bellieres, Alejandro Martínez, Kestutis Grigoras, Teija Häkkinen, Jaakko Saarilahti, Tapani Makkonen, Clivia M Sotomayor-Torres, Jouni Ahopelto

Nanocrystalline materials exhibit properties that can differ substantially from those of their single crystal counterparts. As such, they provide ways to enhance and optimize their functionality for devices and applications. Here, we report on the optical, mechanical and thermal properties of…

Self-organized synchronization of mechanically coupled resonators based on optomechanics gain-loss balance

P. Djorwe, Yan Pennec, Bahram Djafari-Rouhani

We investigate self-organized synchronization in a blue-detuned optomechanical cavity that is mechanically coupled to an undriven mechanical resonator. By controlling the strength of the driving field, we engineer a mechanical gain that balances the losses of the undriven resonator. This gain-loss…

The impact of dislocations on AlGaN/GaN Schottky diodes and on gate failure of high electron mobility transistors

Sven Besendörfer, Elke Meissner, F Medjdoub, Joff Derluyn, Jochen Friedrich, Tobias Erlbacher

GaN epitaxially grown on Si is a material for power electronics that intrinsically shows a high density of dislocations. We show by Conductive Atomic Force Microscopy (C-AFM) and Defect Selective Etching that even for materials with similar total dislocation densities substantially different…

Library of Two-Dimensional Hybrid Lead Halide Perovskite Scintillator Crystals

Aozhen Xie, Francesco Maddalena, Marcin Witkowski, Michal Makowski, Benoit Mahler, Winicjusz Drozdowski, Stuart Victor Springham, Philippe Coquet, Christophe Dujardin, Muhammad Danang Birowosuto, Cuong Dang

Two-dimensional (2D) hybrid lead halide perovskites are potential candidates for high light yield scintillators as they have small band gaps between 3 and 4 eV and large exciton-binding energy. Here, we discuss the scintillation properties from a total of 11 organic/inorganic hybrid perovskite…

Superelement modelling of elastic metamaterials: Complex dispersive properties of three-dimensional structured beams and plates

Domenico Tallarico, Gwenael Hannema, M. Miniaci, Andrea Bergamini, Armin Zemp, Bart van Damme

In this article, we offer a fast calculation method for the dispersive properties of three-dimensional micro-structured solids with one-dimensional and two-dimensional translation symmetry. We review mathematical methods to obtain the complex dispersion diagram for such structures (i.e. the Bloch…

Acousto-optique et composants associés, Acousto-optics and acousto-optical components

Jean-Claude Kastelik, Vincent Laude

L’acousto-optique exploite le phénomène de diffraction de la lumière par les ondes acoustiques. Les composants acousto-optiques sont généralement construits autour d’un milieu solide transparent qui supporte la propagation d’ondes élastiques pour des fréquences de quelques dizaines de mégahertz à…, Acousto-optics refers to the diffraction of light by acoustic waves. Acousto-optical devices are generally designed around a transparent solid supporting the propagation of elastic waves at frequencies ranging from a few tens of MHz to a few GHz. Elastic waves are generated by a transducer driven…
