New decision rules for Fisher discriminant analysis : applied to fault diagnosis

Mohamed Amine Atoui, Vincent Cocquempot

A novel framework for fault diagnosis is proposed. New rules are presented to enhance decisions making under a Bayesian latent mixture model. The proposed decision rules improve Fisher discriminant analysis based scheme. These rules allow it to deal with known and not acknowledged faults.…

An effective thermal conductivity model for architected phase change material enhancer: theoretical and experimental investigations

Romain Hubert, Olivier Bou Matar, Jerome Foncin, Philippe Coquet, Dunlin Tan, Hongling Li, Edwin Hang Tong Teo, Thomas Merlet, Philippe Pernod

Phase Change Materials (pcm) have been widely used for thermal energy storage due to their high latent heat of fusion. However, PCMs suffer from their very low thermal conductivity which limits heat spreading around the heat source. Without proper thermal conductivity enhancement, melting would…

First-principles thermal transport in amorphous Ge 2 Sb 2 Te 5 at the nanoscale

Thuy-Quynh Duong, Assil Bouzid, Carlo Massobrio, Guido Ori, Mauro Boero, Évelyne Martin

Achieving a precise understanding of nanoscale thermal transport in phase change materials (PCMs), such as Ge 2 Sb 2 Te 5 (GST), is the key of thermal management in nanoelectronics, photonic and neuromorphic applications using non-volatile memories. By resorting to a first-principles approach to…

Theoretical analysis of the effect of the interfacial MoSe$_2$ layer in CIGS-based solar cells

Adama Sylla, N’guessan Armel Ignace, Touré Siaka, Jean-Pierre Vilcot

The aim of this work is to analyze the influence of the interfacial MoSe$_2$ layer on the performance of a /n-ZnO/i-ZnO/n-Zn(O,S)/p-CIGS/p⁺-MoSe₂/Mo/SLG solar cell. In this investigation, the numerical simulation software AFORS-HET is used to calculate…

Double-side effect of B/C ratio on BDD electrode detection for heavy metal ion in water

J. Pei, X. Yu, S. Wei, Rabah Boukherroub, Y. Zhang

BDD (Boron-doped Diamond) electrode may hold a promising application to detect heavy metal ions for actual water monitoring and early warning, but a poor understanding of influence mechanism of B/C ratio on detection performance is in the way of its fabrication and application. This work is…

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…

Vertical Engineering for Large Brillouin Gain in Unreleased Silicon-Based Waveguides

L. Mercadé, A.V. Korovin, Yan Pennec, J. Ahopelto, Bahram Djafari-Rouhani, A. Martínez

Strong acousto-optic interaction in high-index waveguides and cavities generally requires the releasing of the high-index core to avoid mechanical leakage into the underlying low-index substrate. This complicates fabrication, limits thermalization, reduces the mechanical robustness, and hinders…
