ILC-Unet++ for Covid-19 Infection Segmentation

Fares Bougourzi, Cosimo Distante, Fadi Dornaika, Abdelmalik Taleb-Ahmed, Abdenour Hadid

Since the appearance of Covid-19 pandemic, in the end of 2019, Medical Imaging has been widely used to analysis this disease. In fact, CT-scans of the Lung can help to diagnosis, detect and quantify Covid-19 infection. In this paper, we address the segmentation of Covid-19 infection from CT-scans....

Monitoring saltwater corrosion of steel using ultrasonic coda wave interferometry with temperature control

Maxime Farin, Emmanuel Moulin, Lynda Chehami, Farouk Benmeddour, Cyril Nicard, Pierre Campistron, Olivier Bréhault, Lucie Dupont

Assessing corrosion is crucial in the petrochemical and marine industries. Usual ultrasonic methods based on pulse-echo and guided waves to detect corrosion lack of precision and struggle in structures with a complex shape. In this paper, a complementary and sensitive ultrasonic method based on...

Ultrasound WPC tomography of a nonlinear parameter

Yu. Pylnov, L. Krutyansky, V. Preobrazhensky, Philippe Pernod

A possibility of using a standard beam tomography procedure to reconstruct the two-dimensional distribution of the nonlinear parameter of a medium in ultrasonic systems with wave phase conjugation (WPC) is investigated. The mathematical model constructed for the confocal geometry of the ultrasonic...

Analyzing the Mechanism of Zinc Oxide Nanowires Bending and Bundling Induced by Electron Beam under Scanning Electron Microscope Using Numerical and Simulation Analysis

Basma El Zein, Ali Elrashidi, El Hadj Dogheche, Ghassan Jabbour

The bending effect of self-catalyst zinc oxide nanowires on a photoconducting behavior has been investigated by in-situ scanning electron microscope method and interpreted by analytical modeling. Zinc oxide NWs tend to incline due to geometric instability and because of the piezoelectric properties...

Investigation of luminescence centers inside InGaN/GaN multiple quantum well over a wide range of temperature and injection currents

Neslihan Ayarcı Kuruoğlu, Orhan Özdemir, Kutsal Bozkurt, Hanife Baş, Bandar Alshehri, Karim Dogheche, El Hadj Dogheche

InGaN/GaN multiple quantum well-based light-emitting diode LEDs were investigated over a wide range of injection currents (0.04 mA–0.1 A) and temperature (80–370 K)-dependent electroluminescence EL measurements. Two centers were identified for blue luminescence peaking at 2.9 eV and 3.0 eV, denoted...

Comprehensive model for ideal reverse leakage current components in Schottky barrier diodes tested in GaN-on-SiC samples

B. Orfao, G. Di Gioia, B. Vasallo, S. Pérez, J. Mateos, Yannick Roelens, E. Frayssinet, Y. Cordier, M. Zaknoune, T. González

A model to predict the ideal reverse leakage currents in Schottky barrier diodes, namely, thermionic emission and tunneling components, has been developed and tested by means of current–voltage–temperature measurements in GaN-on-SiC devices. The model addresses both current components and both...

Growth and design strategies of organic dendritic networks

Giuseppe Ciccone, Matteo Cucchi, Yanfei Gao, Ankush Kumar, Lennart Maximilian Seifert, Anton Weissbach, Hsin Tseng, Hans Kleemann, Fabien Alibart, Karl Leo

Abstract A new paradigm of electronic devices with bio-inspired features is aiming to mimic the brain’s fundamental mechanisms to achieve recognition of very complex patterns and more efficient computational tasks. Networks of electropolymerized dendritic fibers are attracting much interest because...

Imaging of THz photonic modes by scattering scanning near-field optical microscopy

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

We investigated the near-field distribution associated to the photonic mode of terahertz photonic micro-resonators by scattering scanning near-field optical microscopy. Probing individual THz microresonators concentrating electric field is important for high-sensitivity chemical and biochemical...
