Active control of the transmission of Lamb waves through an elastic metamaterial

W. Wang, B. Bonello, Bahram Djafari-Rouhani, X. Fang, Yan Pennec, J. Zhao, Y. Jin

We have numerically investigated the transmission of an antisymmetric Lamb wave through a line of silicon pillars erected onto a homogeneous silicon plate when the frequency is tuned to a resonant frequency of the pillars. For either a bending mode or a compressional mode, the resonators emit in…

Reference-free damage localization based on pump-probe measurements

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

Nondestructive testing is often based on comparison between experimental data measured on damaged and intact samples. However, properties of intact samples can change with time, temperature or other external factors. An alternative approach discussed here solely uses data obtained on a damaged…

Subcellular imaging during single cell mechanical characterization

Deniz Pekin, Gregoire Perret, Quentin Rezard, Jean Claude Gerbedoen, Samuel Meignan, Dominique Collard, Chann Lagadec, Mehmet Tarhan

We report a method for combining confocal microscopy with single-cell mechanical characterization. This method allows investigating the effect of subcellular deformation (e.g. membranes, cytoplasm, cytoskeleton and organelles as endoplasmic reticulum, mitochondria, and nucleus) on cell mechanical…

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…

Power-efficient reliable register file for aggressive-environment applications

Ihsen Alouani, Hamzeh Ahangari, Özcan Özturk, Smail Niar

In a context of increasing demands for on-board data processing, insuring reliability under reduced power budget is a serious design challenge for embedded system manufacturers. Particularly, embedded processors in aggressive environments need to be designed with error hardening as a primary goal,…

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…
