Inducing dispersion curves with negative group velocity in inertially amplified phononic crystals through the application of an external state of prestress

M. Miniaci, M. Mazzotti, A. Amendola, F. Fraternali

In this paper, we report about the effect of the application of a state of prestress on the band structure of a periodic phononic crystal characterized by an inertial amplification mechanism. Through a numerical example, we show the possibility of inducing negative group velocity in an isolated...

L'infini au cours des siècles

Stefano Giordano, Manon Benedito

The fascinating history of the concept of infinity is indissolubly associated with the development of religions, philosophies, mathematics and natural sciences. At the time of the first Greek philosophers, the infinity, or áperion, was a negative concept to be avoided in all rigorous statements....

Eve, you shall not get access! A cyber-physical blockchain architecture for electronic toll collection security

Ahmed Didouh, Anthony Bahadir Lopez, Yassin El Hillali, Atika Rivenq, Mohammad Abdullah Al Faruque

Cooperative intelligent transportation system (C-ITS) applications are generally susceptible to position spoofing-dependent attacks such as Sybil and DDoS attacks due to a lack of established solutions. This paper presents a novel cyber-physical blockchain cryptographic architecture to help prevent...

Frequency-domain simulation of power electronic systems based on multi-topology equivalent sources modelling method

Stephane Vienot, Arnaud Videt, Nadir Idir, Lamine Kone, Sebastien Weiss, Frederic Lafon

ElectroMagnetic Interference (EMI) simulation of power converters helps engineers in the design process. In this paper, we describe a frequency-domain simulation method based on the Multi-Topology Equivalent Sources (MTES) model. The aim is to reproduce the non-linear behavior of power switches for...

Smart way to adjust Schottky barrier height in 130 nm BiCMOS process for sub-THz applications

Vincent Gidel, Frederic Gianesello, Pascal Chevalier, Gregory Avenier, Nicolas Guitard, Michel Buczko, Cyril Luxey, Guillaume Ducournau

In this paper, an innovative Schottky diode architecture is proposed and implemented in 130 nm BiCMOS technology. A state-of-the-art 1 THz cut-off frequency is measured and an innovative way to modify the height of the Schottky barrier is proposed. This smart way could enable zero-bias high-...

Effect of substrate moisture content on sound absorption by green systems

Emmanuel Attal, Nicolas Côté, Takafumi Shimizu, Bertrand Dubus

Sound and noise reflections from acoustically rigid materials constituting buildings and roads contribute strongly to acoustic environment in urban areas. Building envelope greening which improves noticeably sound absorption, may be a solution for acoustic protection in cities when applied in a...

Development of High Frequency Interdigital Transducers for NDT of Thin Films

Tahar Kadi, Marc Duquennoy, Mohammadi Ouaftouh, Nikolay Smagin, Frédéric Jenot

Various engineering systems components suffer destructive effects on their surfaces, like wear, fatigue, or corrosion during their operation. Protecting the surface by hardening treatments or applying coatings is a widespread way to extend their life and improve the product quality. Important...
