Model selection for support-vector machines through metaheuristic optimization algorithms

Oumeima Ghnimi, Sofiane Kharbech, Akram Belazi, Ammar Bouallegue

A machine learning algorithm aims at designing a mathematical model based on a given training data set. Generally, the built model has a set of parameters that need to be adjusted. Since the performance of a given model depends on its settings, the parameters have to be carefully chosen through a...

SERS characterization of aggregated and isolated bacteria deposited on silver-based substrates

Cristina-Cassiana Andrei, Anne Moraillon, Eric Larquet, Monica Potara, Simion Astilean, Endre Jakab, Julie Bouckaert, Léa Rosselle, Nadia Skandrani, Rabah Boukherroub, Francois Ozanam, Sabine Szunerits, Anne Chantal Gouget-Laemmel

Surface-enhanced Raman scattering (SERS), based on the enhancement of the Raman signal of molecules positioned within a few nanometres from a structured metal surface, is ideally suited to provide bacterial-specific molecular fingerprints which can be used for analytical purposes. However, for some...

Towards the use of flapping wing nano aerial vehicles

Sébastien Grondel, Mathieu Colin, Marie Zwingelstein, Sofiane Ghenna, Caroline Soyer, Eric Cattan, Olivier Thomas

In the last decade, the potential of Micro Aerial Vehicles (MAVs) has generated an enormous interest in this technology and numerous applications have therefore been proposed in military and civilian fields. More recently, researchers have begun to work on a new and miniaturized generation called...

Measurement of the V2I massive radio channel with the MaMIMOSA sounder in a suburban environment

Davy Gaillot, Pierre Laly, N Dahmouni, Gauthier Delbarre, M van den Bossche, G Vermeeren, E Tanghe, Eric Pierre Simon, W Joseph, L Martens, M. Lienard

This paper presents the first V2I channel sounding campaign with the real-time massive MIMO radio channel sounder named MaMIMOSA. This equipment has been jointly developed by ULille (FR) and UGhent (BE) for 5G V2X applications. The system is equipped with a massive 64-antenna array for Tx whereas...

Bias Tunable Spectral Response of Nanocrystal Array in a Plasmonic Cavity

Tung Huu Dang, Angela Vasanelli, Yanko Todorov, Carlo Sirtori, Yoann Prado, Audrey Chu, Charlie Gréboval, Adrien Khalili, Herve Cruguel, Christophe Delerue, Gregory Vincent, Emmanuel Lhuillier

Nanocrystals (NCs) have gained considerable attention for their broadly tunable absorption from the UV to the THz range. Nevertheless, their optical features suffer from a lack of tunability once integrated into optoelectronic devices. Here, we show that tunable absorption with bias can be obtained...

ESD mm-wave-circuit protection: 3-dB couplers

Marc Margalef-Rovira, Géraldine Pelletier, Vanessa Avramovic, Sylvie Lepilliet, Johan Bourgeat, Jean-Marc Duchamp, Manuel J. Barragan, Emmanuel Pistono, Sylvain Bourdel, Christophe Gaquière, Philippe Ferrari

This article presents an innovative architecture for the implementation of an electrostatic discharge (ESD) protection for millimeter-wave (mm-wave) devices. The proposed architecture is based on the use of 3-dB couplers, whose coupled outputs have been shorted to the ground node. In order to...

Third order notch over multi-bias and temperature in GaN and GaAs HEMTs

M.A. Alim, A.A. Rezazadeh, Christophe Gaquière

A detailed study about the shifting of third-order notch and threshold voltage with temperature for GaN and GaAs FETs were analyzed. For this purpose, a great deal of data over temperature between-40 to 150°C were measured by using two-tone intermodulation distortion set up. It was found that the...
