Improvement of emotion recognition from facial images using deep learning and early stopping cross validation

Mohamed Bentoumi, Mohamed Daoud, Mohamed Benaouali, Abdelmalik Taleb-Ahmed

Inthis paper, we present a new approach for emotion recognition from facial images. The proposed method is based on the association of a pretrained convolutional neural network (CNN) model (VGG16, ResNet50) with a multilayer perceptron (MLP) classifier. The pretrained CNN model is used as a feature…

Statistical mechanics of rate-independent stick-slip on a corrugated surface composed of parabolic wells

Stefano Giordano

The stick-slip phenomenon, at the basis of friction, is crucial for several applications ranging from nanotechnology and biophysics to mechanics and geology. Deep understanding of friction mechanisms and, in particular, the methodologies for its reduction must be sought in its nanoscopic nature,…

Nano drone bioinspiré à ailes vibrantes

Marguerite de la Bigne, Mathieu R Colin, Sofiane Ghenna, Eric Cattan, Grondel Sébastien, Olivier Thomas

Cet exposé montre les derniers travaux sur le dimensionnement d’un nanodrone bio-inspiré à ailes vibrantes. Cette étude s’intègre à un projet qui a pour objectif de faire décoller le plus petit drone au monde. Son originalité réside dans les techniques de fabrication utilisées, puisque le drone est…

A multiline InP-TRL kit for sub-mmWave characterization of InP-HEMT

R. Younes, Nicolas Wichmann, Sylvie Lepilliet, Guillaume Ducournau, S. Bollaert

We investigate the development of on-wafer multiline Thru-Reflect-Line calibration kits to enable transistor characterization beyond 110 GHz. The final objective is to measure the S parameters of a HEMT having a very high cut-off frequency (up to THz range). A first kit design shows that the use of…

Traveling wave photomixers based on low-temperature-grown Gallium Arsenide reaching 50 mA/W under 1550 nm CW illumination

Charbel Tannoury, Vanessa Avramovic, Etienne Okada, Christophe Coinon, Jean-Francois Lampin, Emilien Peytavit

In this work we present an original design of a traveling-wave photomixer (TWP) based on low-temperature-grown GaAs layer (LT-GaAs) optimized for 1550 nm wavelength excitation. The optical wave is absorbed in the LT-GaAs through an integrated silicon nitride-based waveguide. The optical waveguide…

Split-ring resonators imaged by THz s-SNOM

Cristiane Santos, Theo Hannotte, Louis Thomas, Benjamin Walter, Melanie Lavancier, Sophie Eliet, Marc Faucher, Jean-Francois Lampin, Romain Peretti

Split-ring resonators (SRRs) are one of the most common building blocks to design metamaterials operating over a large range of frequencies in the electromagnetic spectrum. Here we acquire s-SNOM images with high signal-to-noise ratio on SRRs by scattering-type scanning near-field optical…
