Serial interference cancellation for improving uplink in LoRa-like networks

Angesom Ataklity Tesfay, Eric Pierre Simon, Guillaume Ferré, Laurent Clavier

In this paper, we present a new receiver design, which significantly improves performance in the Internet of Things networks such as LoRa, i.e., having a chirp spread spectrum modulation. The proposed receiver is able to demodulate multiple users simultaneously transmitted over the same frequency…

Toward the growth of self-catalyzed ZnO nanowires perpendicular to the surface of silicon and glass substrates, by pulsed laser deposition

Basma El Zein, Yingbang Yao, Ahmad S. Barham, El Hadj Dogheche, Ghassan E. Jabbour

Vertically-oriented zinc oxide (ZnO) nanowires were synthesized on glass and silicon substrates by Pulsed Laser Deposition and without the use of a catalyst. An intermediate c-axis oriented nanotextured ZnO seed layer in the form of nanowall network with honey comb structure allows the growth of…

New Bacteriocins from Lacticaseibacillus paracasei CNCM I-5369 Adsorbed on Alginate Nanoparticles Are Very Active against Escherichia coli

Yanath Belguesmia, Noura Hazime, Isabelle Kempf, Rabah Boukherroub, Djamel Drider

Lacticaseibacillus paracasei CNCM I-5369, formerly Lactobacillus paracasei CNCM I-5369, produces bacteriocins that are remarkably active against Gram-negative bacteria, among which is the Escherichia coli-carrying mcr-1 gene that is involved in resistance to colistin. These bacteriocins present in…

Near-field measurement and far-field characterization of a J-band antenna based on an electro-optic sensing

Shintaro Hisatake, Yusuke Tanaka, Cybelle Belem-Gonçalves, Cyril Luxey, Frédéric Gianesello, Guillaume Ducournau, Akihiko Hirata

In this paper, we present a near-field pattern measurement based on an electro-optic sensing at 300 GHz band. The measurement system is based on a self-heterodyne technique and non-polarimetric frequency down-conversion technique. The far-field radiation pattern of a horn antenna calculated from…

Mechanisms of a rectifying TiN gate contact for AlGaN/GaN HEMTs on silicon substrate

Hassane Ouazzani Chahdi, Brahim Benbakhti, Maghnia Mattalah, Jean Claude Gerbedoen, Abdelatif Jaouad, Nour Eddine Bourzgui, Ali Soltani

Rectifying Titanium Nitride (TiN) gate contact technology is developed for AlGaN/GaN based micro and nanometer HEMTs. A high compressive strain occurring in thinner TiN films (ranging from 5 nm to 60 nm), deposited by sputtering, leads to a reduction in tensile strain at the surface of AlGaN…

Application of the GPR and ERT methods for non-invasive examination of a flood dike

Tomislaw Golebiowski, Bogdan Piwakowski, Michal Cwiklik

As part of the NAWA-EMMAT project, geophysical surveys were carried out on selected sites in Poland, i.e. on the flood dike and in the surrounding of the concrete water dam. The goal of the surveys was the non-invasive detection of loose zones in the flood dike and fractured zones located in the…
