Multi-Channel Generative Framework and Supervised Learning for Anomaly Detection in Surveillance Videos

Tuan-Hung Vu, Jacques Boonaert, Sébastien Ambellouis, Abdelmalik Taleb-Ahmed

Recently, most state-of-the-art anomaly detection methods are based on apparent motion and appearance reconstruction networks and use error estimation between generated and real information as detection features. These approaches achieve promising results by only using normal samples for training…

UWB radar detection theory

Laila Sakkila, C. Tatkeu, Atika Rivenq, J. Zaidouni, Michael Bocquet

In this paper, a study of UWB receivers in terms of detection theory is presented. The UWB radar which is presented in many works previously [1]-[3] has many applications. For road UWB radar application, the receiver based on correlation is the optimum receiver [4]. In fact, it maximizes the…

Concept Extraction Based on Semantic Models Using Big Amount of Patents and Scientific Publications Data

Vasilii Kaliteevskii, Arthur Deder, Nemanja Peric, Leonid Chechurin

Formalisation of heuristic methods for supporting the conceptual design stage of product and technology development has been extensively evolved in industry during the last half of the century and gradually more formally appears in academic context nowadays. Due to the considerable interest from…

Two-tone intermodulation performance of a 300GHz power amplifier MMIC

B. Schoch, A. Tessmann, A. Leuther, P. Szriftgiser, Guillaume Ducournau, I. Kallfass

Intermodulation effects play a decisive role in any system relying on the linear transmission of signals, such as highspeed wireless communication. For the first time, this paper presents measured third-order and fifth-order intermodulation performance of a 300GHz monolithic integrated circuit with…

Acoustic Tamm states in slender tubes

S. Khattou, M. Amrani, A. Mouadili, E.H. El Boudouti, Bahram Djafari-Rouhani

We present an analytical and numerical study of the possibility of existence of surface localized modes, the so-called Tamm states, in a one-dimensional (1D) comb-like phononic crystal (PnC). The structure is made out of periodic array of stubs of lengths d2grafted along a waveguide and separated…

A generalized deep learning-based framework for assistance to the human malaria diagnosis from microscopic images

Ziheng Yang, Halim Benhabiles, Karim Hammoudi, Feryal Windal, Ruiwen He, Dominique Collard

Malaria is an infectious disease caused by Plasmodium parasites and is potentially human life-threatening. Children under 5 years old are the most vulnerable group with approximately one death every two minutes, accounting for more than 65% of all malaria deaths. The World Health Organization (WHO…

Temperature Sensitivity of Surface Phononic Crystals modes (SPnC) based on Ni Pillars array deposited on LiNBO3

Abdelkrim Talbi, Ghizlane Boussatour, Aurelien Mazzamurro, Cécile Ghouila-Houri, Olivier Boumatar, Philippe Pernod

This work focuses on the theoretical and experimental investigation of acoustic waves sensors based on 2D Surface Phononic Crystals (PnC). We investigated the temperature coefficient of frequency (TCF) for surface localized modes in 2D PnCs composed of Ni pillars deposited on Y-cut LiNBO3 substrate…

Thermoacoustic wave generation in multilayered thermophones with cylindrical and spherical geometries

Pierre Guiraud, Stefano Giordano, Olivier Bou Matar, Philippe Pernod, Raphael Lardat

A thermoacoustic sound generation model, based on the classical balance equations of the continuum mechanics, is here developed for the cylindrical and the spherical thermoacoustic wave generation. In both geometries, the model considers an arbitrary multilayered structure, where each layer can be…

Growth temperature effect on physical and mechanical properties of nitrogen rich InN epilayers

Z. Benzarti, T. Sekrafi, A. Khalfallah, Zahia Bougrioua, D. Vignaud, M. Evaristo, A. Cavaleiro

A set of N-polar InN epilayers has been grown at different temperatures by plasma-assisted molecular beam epitaxy (PA-MBE) on GaN/AlN/Al2O3(0001) templates. The purpose is to understand how the variation of crucial factor, such as the temperature, impacts the growth process and the resulting…

Bias-dependence of surface charge at low temperature in GaN self-switching diodes

E. Perez-Martin, I. Iniguez-De-La-Torre, T. Gonzalez, Christophe Gaquière, J. Mateos

In this work, with the help of a semi-classical two-dimensional Monte Carlo (MC) simulator, we study the DC current-voltage curves of Self-Switching Diodes (SSDs) fabricated on an AlGaN/GaN heterostructure from 100 K up to room temperature. Due to the very narrow channel of the SSDs, the presence…
