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...

Single-pole-double-throw RF switches based on monolayer MoS₂

Myungsoo Kim, Emiliano Pallecchi, Henri Happy, Deji Akinwande

Recently, low-power analog switches have been enjoying rapidly growing interest owing to their proliferation in mobile and reconfigurable communication and connectivity systems often with multiple-input-multiple-output architecture [1] , [2] . To develop this ideal switch, non-volatile switches...

Evolution of localized surface plasmon resonance made of gold nanowire chain embedded in WS2multilayers

Z. Oumekloul, Y. Achaoui, A. Mir, Abdellatif Akjouj

Recently, the transition metal dichalcogenides (TMDs) have emerged as a new class of building blocks for engineering enhanced plasmonic sensors. This class of materials can be made with a low production cost and can be easily hybridized with metallic nanoparticles whereby desired molecules are...

Piezoresistance in defect-engineered silicon

Heng Li, Abel Thayil, Chris Lew, Marcel Filoche, Brett Johnson, Jeff Mccallum, S. Arscott, Alistair C. H. Rowe

The steady-state, space-charge-limited piezoresistance (PZR) of defect-engineered, silicon-on-insulator device layers containing silicon divacancy defects changes sign as a function of applied bias. Above a punch-through voltage (Vt) corresponding to the onset of a space-charge-limited hole current...

Radiation environment and doses on Mars at Oxia Planum and Mawrth Vallis: support for exploration at sites with high biosignature preservation potential

F. da Pieve, G. Gronoff, J. Guo, C. J. Mertens, L. Neary, B. Gu, N. E. Koval, J. Kohanoff, A. C. Vandaele, F. Cleri

The first human missions on MARS will likely involve several astrobiology‐driven science operations, at sites with high biosignature preservation potential. Here, we present a study of the radiation environment induced by Galactic Cosmic Rays and Solar Energetic Particles at OXIA PLANUM, landing...

Optimization of Reactive-Ion Etching (RIE) parameters to maximize the lateral etch rate of silicon using SF6/N2 gas mixture: An alternative to etching Si in MEMS with Au components

Munique Kazar Mendes, Cécile Ghouila-Houri, Serria Hammami, Thomas Arnoult, Philippe Pernod, Abdelkrim Talbi

In this work, the effects of the N2 addition to the SF6 plasma used in the isotropic silicon etching of Microelectromechanical systems (MEMS) with Au components are investigated. A four-variables Doehlert design was implemented for optimizing the etching parameters (power, pressure, gas flow rate,...
