A fuzzy/possibility approach for area coverage in wireless sensor networks

Adda Boualem, Cyril de Runz, Marwane Ayaida, Herman Akdag

The literature approaches, devoted to sensor improve network coverage, are deterministic in terms of deployment environment and node configuration parameters. Nevertheless, this type of approaches has not proven to be very successful in uncertain deployment environments. This paper aims to deal...

Fiber-tip spintronic terahertz emitters

Felix Paries, Nicolas Tiercelin, Geoffrey Lezier, Mathias Vanwolleghem, Felix Selz, Maria-Andromachi Syskaki, Fabian Kammerbauer, Gerhard Jakob, Martin Jourdan, Mathias Kläui, Zdenek Kaspar, Tobias Kampfrath, Tom Seifert, Georg von Freymann, Daniel Molter

Spintronic terahertz emitters promise terahertz sources with an unmatched broad frequency bandwidth that are easy to fabricate and operate, and therefore easy to scale at low cost. However, current experiments and proofs of concept rely on free-space ultrafast pump lasers and rather complex...

Acoustic Wave Generation in Nanofluids: Effect of the Kapitza Resistance on the Thermophone to Mechanophone Generation Mechanism Transition

Stefano Giordano, Michele Diego, Francesco Banfi

High frequency, short wavelength acoustic wave generation in fluids, by means of immersed nanotransducers, is key to applications ranging from the biomedical to the ICT sector, all the way to investigating fundamental aspects of the mechanics of fluids. In this context, the commonly adopted...

Thermodynamics of a single mesoscopic phononic mode

Ilya Golokolenov, Arpit Ranadive, Luca Planat, Martina Esposito, Nicolas Roch, Xin Zhou, Andrew Fefferman, Eddy Collin

In recent decades, the laws of thermodynamics have been pushed down to smaller and smaller scales, within the field of stochastic thermodynamics and state-of-art experiments performed on mesoscopic systems. But these measurements concern mostly thermal properties of electrons and photons. Here we...

The Role of Ferromagnetic Layer Thickness and Substrate Material in Spintronic Emitters

Arseniy Buryakov, Pavel Avdeev, Dinar Khusyainov, Nikita Bezvikonnyy, Andreas Coclet, Alexey Klimov, Nicolas Tiercelin, Sergey Lavrov, Vladimir L. Preobrazhensky

In this article, we investigate optically induced terahertz radiation in ferromagnetic FeCo layers of varying thickness on Si and SiO2 substrates. Efforts have been made to account for the influence of the substrate on the parameters of the THz radiation generated by the ferromagnetic FeCo film....

Explainable root cause and pathway analysis with robust and adaptive statistics

Mohamed Amine Atoui, Vincent Cocquempot

Accurate detection of faults is desired to reduce risks and costs. The identification of the propagation path of faults and the system’s variables responsible of faulty operating conditions is also paramount. This paper presents a new alternative to a well-known Bayesian network-based approach to...

Compact localized boundary states in a quasi-1D electronic diamond-necklace chain

S. Kempkes, Pierre Capiod, S. Ismaili, J. Mulkens, L. Eek, I. Swart, C. Morais Smith

Zero-energy modes localized at the ends of one-dimensional (1D) wires hold great potential as qubits for fault-tolerant quantum computing. However, all the candidates known to date exhibit a wave function that decays exponentially into the bulk and hybridizes with other nearby zero-modes, thus...

Silicon Based Suspended Thermometry Device Fabrication for Phonon Ballistic and Coherent Regimes Study

J. Canosa Diaz, H. Ikzibane, B. Brisuda, C. Polanco Garcia, L. Saminadayar, N. Mingo, Olivier Bourgeois, Emmanuel Dubois, J.F. Robillard

This works addresses the current experimental gap in thermal transport regimes and phonon transport at low temperatures and small scales. We have fabricated a (SOI based) suspended thermal sensor platform functional from room-T down to 20 mK. The device will be used for the study phonon transport...

Oscillations and Cavity Modes in the Circular Hydraulic Jump

Aurélien Goerlinger, Michael Baudoin, Farzam Zoueshtiagh, Alexis Duchesne

We report spontaneous oscillations of circular hydraulic jumps created by the impact of a submillimeter water jet on a solid disk. The jet flow rate is shown to condition the occurrence of the oscillations while their period is independent of this parameter. The period, however, varies linearly...

A self-purifying microfluidic system for identifying drugs acting against adult schistosomes

Vincent Girod, Robin Houssier, Karin Sahmer, Marie-José Ghoris, Stéphanie Caby, Oleg Melnyk, Colette Dissous, Vincent Senez, Jérôme Vicogne

The discovery of novel antihelmintic molecules to combat the development and spread of schistosomiasis, a disease caused by several Schistosoma flatworm species, mobilizes significant research efforts worldwide. With a limited number of biochemical assays for measuring the viability of adult worms...
