Leveraging Efficient Models for Recognizing Drivers' Facial Expressions

Ibtissam Saadi, Douglas W Cunningham, Abdelmalik Taleb-Ahmed, Abdenour Hadid, Yassin El Hillali

Our new approach, ShuffViT-DFER, combines lightweight CNN and vision transformer models for efficient and accurate real-time driver facial expression recognition. By merging their features effectively, we outperform existing methods on benchmark datasets like KMU-FED and KDEF.

EME-CNTK: Infinite Limits of Convolutional Neural Network for Urban Electromagnetic Field Exposure Reconstruction

Mohammed Mallik, Benjamin Allaert, E. Egea-Lopez, D.P. Gaillot, J. Wiart, L. Clavier

Electromagnetic field (EMF) exposure has grown to be a critical concern as a consequence of the ongoing installation of fifth-generation cellular networks (5G). The lack of measurements makes it difficult to accurately assess the EMF in a specific urban area, as Spectrum cartography (SC) relies on...

Design and testing of a multi-electrode apodized acousto-optic filter for arbitrary polarized light

Samuel Dupont, Jean-Claude Kastelik, Jurgen Vanhamel

We present an original acousto-optic tunable filter that is able to filter visible light from 400 to 650 nm and is designed to interact simultaneously with two polarizations. The filter shows an adjustable optical bandwidth and apodization capabilities. These features make it suitable for practical...

Comparison of Impedance Matching Networks for Scanning Microwave Microscopy

Johannes Hoffmann, Sophie de Préville, Bruno Eckmann, Hung-Ju Lin, Benedikt Herzog, Kamel Haddadi, Didier Theron, Georg Gramse, Damien Richert, José Morán-Meza, François Piquemal

In this paper, a definition of the gain and added noise of impedance matching networks for scanning microwave microscopy is given. This definition can be used to compare different impedance matching techniques independently of the instrument used to measure the S-parameter. As a demonstration,..., Cet article donne une définition du gain et du bruit ajouté par les circuits d'adaptation d'impédance utilisés pour la microscopie en champ proche en hyperfréquences. Cette définition peut être utilisée pour comparer différentes techniques d'adaptation d'impédance indépendamment...

Boosting Gas-Phase TiO 2 Photocatalysis with Weak Electric Field Strengths of Volt/Centimeter

My Nghe Tran, Myriam Moreau, Ahmed Addad, Adrien Teurtrie, Thomas Roland, Vincent de Waele, Marc Dewitte, Louis Thomas, Gaëtan Lévêque, Chunyang Dong, Pardis Simon, Karima Ben Tayeb, David Mele, Vitaly Ordomsky, Bruno Grandidier

Among the semiconductor nanomaterials, titanium dioxide is at the forefront of heterogeneous photocatalysis, but its catalytic activity greatly suffers from the loss of photoexcited charge carriers through deleterious recombination processes. Here, we investigate the impact of an external electric...
