Detection of cyber-attacks on Wi-Fi networks by classification of spectral data

Jonathan Villain, Virginie Deniau, Anthony Fleury, Christophe Gransart, Eric Pierre Simon

In many areas, communications or computer networks include both wired and wireless sections. In this research, we are interested in the wireless network sections. This part of the networks can targeted by denial of service attacks, affecting the reception quality of communication signals, or by...

Detection and evaluation of macro-cracks and micro-cracking by using automated surface wave non-contact scanners

Charles Ciccarone, Bogdan Piwakowski, Frédéric Skoczylas, Radoslaw Drelich, Jean-Marie Henault

The goal of the presented work is the detection and evaluation of cracks, in the VeRCoRs mock-up which constitutes the double-wall containment building of a Nuclear Power Plant in scale 1/3. The experiments are conducted in situ, on the inner wall of the VeRCoRs mock-up. The detection is performed...

An ultra-high bandwidth nano-electronic interface to the interior of living cells with integrated fluorescence readout of metabolic activity

Dandan Ren, Zahra Nemati, Chia-Hung Lee, Jinfeng Li, Kamel Haddadi, Douglas C. Wallace, Peter J. Burke

We present the first ever broadband, calibrated electrical connection to the inside of a cell. The interior of a vital, living cell contains multiple dynamic and electrically active organelles such as mitochondria, chloroplasts, lysosomes, and the endoplasmic reticulum. However, little is known...

Characterization of 1-3 Piezocomposite Using Lamb Waves Propagation

Rémi Rouffaud, Anne-Christine Hladky, Dominique Certon, Antoine Balé, Franck Levassort

Due to their enhanced electromechanical properties with respect to conventional piezoelectric ceramics, 1-3 piezocomposite (1-3PC) materials are predominant in high performance ultrasonic array. Their complete effective electroelastic modulus (EEM) has a significant importance for numerical...

Experimental observation and modeling of the impact of traps on static and analog/HF performance of graphene transistors

Anibal Pacheco-Sanchez, Nikolaos Mavredakis, Pedro C. Feijoo, Wei Wei, Emiliano Pallecchi, Henri Happy, David Jimenez

The trap-induced hysteresis on the performance of a graphene field-effect transistor is experimentally diminished here by applying consecutive gate-to-source voltage pulses of opposing polarity. This measurement scheme is a practical and suitable approach to obtain reproducible device...

Long-range electron transport in Prussian blue analog nanocrystals

Roméo Bonnet, Stéphane Lenfant, Sandra Mazérat, Talal Mallah, Dominique Vuillaume

We report electron transport measurements through nano-scale devices consisting of 1 to 3 Prussian blue analog (PBA) nanoparticles connected between two electrodes. We compare two types of cubic nanoparticles, CsCoIIIFeII (15 nm) and CsNiII...

A superheterodyne 300 GHz wireless link for ultra-fast terahertz communication systems

Iulia Dan, Guillaume Ducournau, Shintaro Hisatake, Pascal Szriftgiser, Ralf-Peter Braun, Ingmar Kallfass

A superheterodyne transmission scheme is adopted and analyzed in a 300 GHz wireless point-to-point link. This was realized using two different intermediate frequency (IF) systems. The first uses fast digital synthesis which provides an IF signal centered around a carrier frequency of 10 GHz. The...

Cyclostationary-based vital signs detection using microwave radar at 2.5 GHz

Fatima Sekak, Kawtar Zerhouni, Fouzia Elbahhar, Madjid Haddad, Christophe Loyez, Kamel Haddadi

Non-contact detection and estimation of vital signs such as respiratory and cardiac frequencies is a powerful tool for surveillance applications. In particular, the continuous wave bio-radar has been widely investigated to determine the physiological parameters in a non-contact manner. Since the RF...

Demonstrating full integration process for electroactive polymer microtransducers to realize soft microchips

Lauréline Seurre, Kätlin Rohtlaid, Giao T. M. Nguyen, Caroline Soyer, Sofiane Ghenna, Sébastien Grondel, Frederic Vidal, Barthelemy Cagneau, Cedric Plesse, Eric Cattan

Actuation and sensing with electroactive polymers should be a chance for flexible MEMS but their micromachining and integration are still not mature. Some innovative materials and microfabrication processes are still expected. In this paper, a first full elaboration of polymeric microtransducers (...

Distributed clique-based neural networks for data fusion at the edge

Benoit Larras

Distributed smart sensors are more and more used in applications such as biomedical or domestic monitoring. However, each sensor broadcasts data wirelessly to the others or to an aggregator, which leads to energy-hungry sensors not ensuring data privacy. To tackle both challenges, this work...
