Binary sessile drops evaporation: IR and acoustic methods for alcohol concentration tracking at the interface and the surface

Pin Chen, Malika Toubal, Julien Carlier, Souad Harmand, Bertrand Nongaillard, Maxence Bigerelle

Evaporation process of droplets of three pure liquids (water, 1-butanol, and ethanol) and four binary solutions (5 wt % 1-butanol water-based solution and 5, 25, and 50 wt % ethanol−water-based solutions) deposited on hydrophobic silicon substrate was studied under ambient condition. An optical…

Cross-layer design (PHY/MAC/NET) for vehicular ad-hoc networks (VANETs)

Andy Triwinarko, Iyad Dayoub

The MAC protocol of IEEE 802.11p dedicated to vehicular ad-hoc networks (VANETs) is using Distributed Coordination Function (DCF) that prohibits simultaneous transmissions in the same detection area in order to avoid interference between neighboring vehicles. This prohibition causes a temporary…

Interaction of ultrasonic waves with damage by exploiting the transmission of digital data using guided waves: application to smart vehicle

Rudy Bahouth, Farouk Benmeddour, Emmanuel Moulin, Jamal Assaad

This work aims to compromise between Structural Health Monitoring and information transmission through solid channels mainly for the application of smart vehicles. The purpose of such idea is to transmit digital data of a sensor without using any wires in one hand, and, inspecting defects in many…

Micro-transducers matrix design for structural health monitoring

Hala El Rammouz, Farouk Benmeddour, Jamal Assaad, Emmanuel Moulin, Youssef Zaatar, Ziad Herro

In this work, a two-dimensional (2D) Lithium Niobate (LiNbO3) 36°Y-cut micro-transducers (μTs) matrix design is presented. Two main steps define the fabrication process: electrode deposition and photolithography. These steps are preceded by the optical mask conception, which defines the 2D matrix…

Développement de transducteurs à ondes acoustiques de surface (IDT-SAW) dédiés à la caractérisation ultrasonore des structures revêtues

Tahar Kadi

Les ondes de Rayleigh sont devenues très populaires dans le domaine des essais non destructifs par ultrasons en tant que moyen d’inspecter différentes structures. La présence de défauts, de contraintes résiduelles, et d’autres défauts matériels peuvent être détectés en analysant l’atténuation et la…

Channel estimation schemes for V2X communications based on ITS-G5

Soheyb Ribouh, Atika Rivenq, Yassin El Hillali

In recent years many research projects in Europe such as InterCor, Scoop, Corridor, and C-Roads have focused on cooperative intelligent transport systems (C-ITS). The C-ITS consist of connecting vehicles to each other (V2V) and to infrastructures (V2I) in order to decrease the accident rate in the…

Internet of things system for healthcare applications

Prasaja Wikanta, Andy Triwinarko, Iyad Dayoub, El Hadj Dogheche

The IoT sensor networks used by patients, could support medical staff to diagnose and to monitor continuously. The human body and movement can cause interference which make the sensors retransmit the data. This will increase packet error ratio (PER). Our cross layer protocol take advantages of…

Baseline-free repetitive pump-probe experiment for structural health monitoring

Marina Terzi, Lynda Chehami, Emmanuel Moulin, Nikolay Smagin, Vladislav Aleshin

Baseline-free damage localization methods in structural health monitoring are of interest. We conducted a pump-probe experiment on metal plate. PZT patch generates a probe wave at 20 kHz, a continuous pump of 1 Hz is produced by a shaker. The aim was localization of a steel ball pressed against…
