Novel Centralized Pseudonym Changing Scheme for Location Privacy in V2X Communication

Ahmed Didouh, Yassin El Hillali, Atika Rivenq, Houda Labiod

Vehicular ad hoc networks allow vehicles to share their information for the safety and efficiency of traffic purposes. However, information sharing can threaten the driver’s privacy as it includes spatiotemporal information, and the messages are unencrypted and broadcasted periodically. Therefore,…

Objective assessment of covid-19 severity affecting the vocal and respiratory system using a wearable, autonomous sound collar

D. Ishac, S. Matta, S. Bin, H. Aziz, E. Karam, A. Abche, Georges Nassar

Introduction Since the outbreak began in January 2020, Covid-19 has affected more than 161 million people worldwide and resulted in about 3.3 million deaths. Despite efforts to detect human infection with the virus as early as possible, the confirmatory test still requires the analysis of sputum or…

Autoregressive Modeling Approach for Non-stationary Vehicular Channel Simulation

Marwan Yusuf, Emmeric Tanghe, Frederic Challita, Pierre Laly, Luc Martens, Davy Gaillot, M. Lienard, Wout Joseph

A framework is proposed for long-term vehicular channel simulation based on the vector time-frequency autoregressive (VTFAR) model for a sparse parametric description of nonstationary multivariate random processes. Based on vehicle-to-infrastructure tunnel measurements, we estimate the VTFAR model…

Colloidal II–VI—Epitaxial III–V heterostructure: A strategy to expand InGaAs spectral response

Adrien Khalili, Claire Abadie, Tung Huu Dang, Audrey Chu, Eva Izquierdo, Corentin Dabard, Charlie Gréboval, Mariarosa Cavallo, Huichen Zhang, Stefano Pierini, Yoann Prado, Xiang Zhen Xu, Sandrine Ithurria, Grégory Vincent, Christophe Coinon, L. Desplanque, Emmanuel Lhuillier

For short wave infrared (SWIR) sensing, InGaAs is the leading technology combining high carrier mobility, high homogeneity and complete control over n-top doping. In the meanwhile, numerous alternative materials have tried to compete with InGaAs. Among them, colloidal nanocrystals with narrow band…

Real-time multimode dynamics of terahertz quantum cascade lasers via intracavity self-detection: observation of self mode-locked population pulsations

Hua Li, Wenjian Wan, Ziping Li, J. Cao, Sylvie Lepilliet, Jean-Francois Lampin, Kevin Froberger, Lorenzo Columbo, Massimo Brambilla, S Barbieri

Mode-locking operation and multimode instabilities in Terahertz (THz) quantum cascade lasers (QCLs) have been intensively investigated during the last decade. These studies have unveiled a rich phenomenology, owing to the unique properties of these lasers, in particular their ultrafast gain medium…

Bubbles and liquid films resisting drainage, evaporation and nuclei-induced bursting

Aymeric Roux, Alexis Duchesne, Michael Baudoin

Soap bubbles are by essence fragile and ephemeral. Depending on their composition and environ- ment, bubble bursting can be triggered by gravity-induced drainage and/or the evaporation of the liquid and/or the presence of nuclei. They can also shrink due to the diffusion of the inner gas in the…

Quantization of Acoustic Modes in Dumbbell Nanoparticles

Zuyuan Wang, Hojin Kim, Maria Secchi, Maurizio Montagna, Eric Furst, Bahram Djafari-Rouhani, George Fytas

The vibrational eigenmodes of dumbbell-shaped polystyrene nanoparticles are recorded by Brillouin light spectroscopy (BLS), and the full experimental spectra are calculated theoretically. Different from spheres with a degeneracy of (2l + 1), with l being the angular momentum quantum number, the…

[Review] Intelligent on-demand design of phononic metamaterials

Yabin Jin, Liangshu He, Zhihui Wen, Bohayra Mortazavi, Hongwei Guo, Daniel Torrent, Bahram Djafari-Rouhani, Timon Rabczuk, Xiaoying Zhuang, Yan Li

With the growing interest in the field of artificial materials, more advanced and sophisticated functionalities are required from phononic crystals and acoustic metamaterials. This implies a high computational effort and cost, and still the efficiency of the designs may be not sufficient. With the…

A cost-effective technology to improve power performance of nanoribbons GaN HEMTs

Ali Soltani, Brahim Benbakhti, J.-C. Gerbedoen, Abdelkrim Khediri, Maher, Hassan, Jean-Paul Salvestrini, Abdallah Ougazzaden, Nour Eddine Bourzgui, Hassan Ali Barkad

A cost-effective fabrication process is developed to improve the power performance of AlGaN/GaN High Electron Mobility Transistors (HEMTs). This process uses nitrogen ion (N+) implantation to form multiple parallel NanoRibbons on AlGaN/GaN heterostructures, with thin buffer layer (AlGaN/GaN NR-…

Photocatalytic Performance of Perovskite and Metal–Organic Framework Hybrid Material for the Reduction of N2 to Ammonia

Masoumeh Chamack, Madjid Ifires, Sayed Ali Akbar Razavi, Ali Morsali, Ahmed Addad, Afsanehsadat Larimi, Sabine Szunerits, Rabah Boukherroub

The orthorhombic phase of KNbO3 perovskite has been applied for nitrogen (N-2) photoreduction to ammonia (NH3). However, this material suffers from a low surface area and low ammonia production efficiency under UV light irradiation. To eliminate these barriers, we used a metal-organic framework (…
