A weighted exponential discriminant analysis through side-information for face and kinship verification using statistical binarized image features

Oualid Laiadi, Abdelmalik Ouamane, Abdelhamid Benakcha, Abdelmalik Taleb-Ahmed, Abdenour Hadid

Side-information based exponential discriminant analysis (SIEDA) is more efficient than side-information based linear discriminant analysis (SILDA) in computing the discriminant vectors because it maximizes the Fisher criterion function. In this paper, we develop a novel criterion, named side-…

Single-charge effects in silicon nanocrystals probed by atomic force microscopy: From charge blinking to nanocrystal charging

Thierry Melin, D. Deresmes

We investigate the electrical properties of individual silicon nanocrystals (NCs) by means of atomic/electrostatic force microscopy at atmospheric pressure, with the sensitivity of the elementary charge. Using a tip bias close to the sample surface potential for the sample topography imaging, NCs…

Plasmonic layer as a localized temperature control element for surface plasmonic resonance-based sensors

Sivaramakrishnan Ganesan, Sophie Maricot, J.F. Robillard, Etienne Okada, Mohamed-Taieb Bakouche, Laurent Hay, Jean-Pierre Vilcot

Surface plasmon resonance (SPR) sensing is a well-established high-sensitivity, label-free and real-time detection technique for biomolecular interaction study. Its primary working principle consists of the measurement of the optical refractive index of the medium that is in close vicinity of the…

Monte Carlo analysis of the influence of surface charges on GaN asymmetric nanochannels: bias and temperature dependence

E. Pérez-Martín, I. Íñiguez-De-La-Torre, Christophe Gaquière, T. González, J. Mateos

In this paper, the occupancy of sidewall surface states having a clear signature in the performance of AlGaN/GaN-based self-switching diodes (SSDs) is analyzed using a semi-classical Monte Carlo (MC) simulator in a wide temperature ( T) range, from 100 to 300 K. Experimental I- V curves show an…

Enhancement of both optical and catalytic activity of copper-decorated porous silicon micro-particles

Abderrahmane Hamdi, Chohdi Amri, Rachid Ouertani, El Hadj Dogheche, Hatem Ezzaouia

To the best of our knowledge, this study is the first to investigate the effect of chemical vapour etching (CVE) combined with copper decoration on both the optical and catalytic activities of silicon micro-particles (SiμPs). After exposure to acid vapours emanating from a hot solution of hydrogen…
