Development of PZT-based 18 MHz 2D pMUT array with PDMS waveguide

Xu-Bo Wang, Le-Ming He, Wen-Juan Liu, Shu-Ren Song, Wei-Jiang Xu, Qian Cheng, Antoine Riaud, Jun-Yan Ren, Jia Zhou

For high-resolution ultrasonic imaging, an 18 MHz lead zirconate titanate (PZT) based two-dimensional (2D) piezoelectric micromachined ultrasonic transducers (pMUTs) array with polydimethylsiloxane (PDMS) waveguide are developed. The array is composed of 8 x 16 elements with a pitch of 75 mu m and…

Atomic Structure of Glassy GeTe 4 as a Playground to Assess the Performances of Density Functional Schemes Accounting for Dispersion Forces

Pier Luigi Silvestrelli, Évelyne Martin, Mauro Boero, Assil Bouzid, Guido Ori, Carlo Massobrio

The atomic structure of glassy GeTe4 is obtained in the framework of first-principles molecular dynamics (FPMD) by considering five different approaches for the description of the electronic structure within density functional theory (DFT). Among these schemes, one is not corrected by accounting…

Multiple sequential constraint removal algorithm for channel estimation in vehicular environment

Soheyb Ribouh, Yassin El Hillali, Atika Rivenq

Since the vehicular environment is highly mobile, the transmitted messages are affected by the wireless channel effect. This makes channel estimation one of the important tasks in Vehicle-To-Everything (V2X) communications. In this paper, we propose a novel Multiple Sequential Constraint Removal (…

Validating the CorrectWearing of Protection Mask by Taking a Selfie: Design of a Mobile Application “CheckYourMask” to Limit the Spread of COVID-19

Karim Hammoudi, Adnane Cabani, Halim Benhabiles, Mahmoud Melkemi

In a context of a virus that is transmissive by sputtering, wearing masks appear necessary to protect the wearer and to limit the propagation of the disease. Currently, we are facing the 2019–2020 coronavirus pandemic. Coronavirus disease 2019 (COVID-19) is an infectious disease with first symptoms…
