Robustness to imperfect CSI of power allocation policies in cognitive relay networks

Yacine Benatia, Romain Negrel, Anne Savard, E Veronica Belmega

In this paper, the aim is to study the robustness against imperfect channel state information (CSI) of the power allocation policies maximizing the constrained and non-convex Shannon rate problem in a relay-aided cognitive radio network. The primary communication is protected by a Quality of...

Modélisation Physique d'Interrupteur Moléculaire, Physikalische Modellierung von molekularen Schaltern, Physical Modeling of molecular Switches

Christophe Krzeminski

Cette modeste communication scientifique présente les résultats de modélisation théorique menés sur différentes classes d’interrupteur moléculaire. Initialement, la définition d'un interrupteur moléculaire est un composé bistable c'est-à-dire existant sous la forme de deux états distincts..., This modest communication presents the results of the theoretical modelling of various molecular switches. Initialy, a molecular switch was defined as a bistable compound existing in two different states (open) or (closed) with the influence of a optical stimuli allowing the modulation of the...

Horloges atomiques microondes et optiques à microcellule

Clément Carlé, Anthony Gusching, Moustafa Abdel Hafiz, Shervin Keshavarzi, Ivan Ryger, Vincent Maurice, Nicolas Passilly, Rodolphe Boudot

Nous présentons en premier lieu des travaux visant au développement d’horloges atomiques microondes à microcellule de haute stabilité, basées sur le phénomène de piégeage cohérent de population (CPT). Nous démontrons l’implémentation de séquences d’interrogation impulsionnelles avancées permettant...

[Invited] Challenges to measure RF noise and intermodulation performances of mmW/THz devices

Francois Danneville, Haitham Ghanem, Joao Carlos Azevedo Gonçalves, Sylvie Lepilliet, Daniel Gloria, Guillaume Ducournau

Applications in millimetre wave range and terahertz frequencies keep on increasing. In this context, drastic challenges are faced at measurement level, in particular to extract noise performance and nonlinear properties of devices and circuits used to build the required systems. The aim of this...

Optimization with Quantum Annealing Machines

Samuel Deleplanque

Quantum annealing is a method based on simulated annealing where temperature variations are replaced by quantum fluctuations that cause qubit state transitions. ISING problems and Quadratic Unconstrained Binary Optimization problems (QUBO) can be tackled by quantum annealing-based machines. We can...

Figure of merit and sensitivity enhancement of biosensor LSPR in investigated for visible and near infrared

Mohamed El Barghouti, Oumaima Haidar, Abdellatif Akjouj, Abdellah Mir

We have proposed new localized surface plasmon (LSP) hybrid nanostructures, based on gold nanowires form T (AuNWs-T) deposited on a glass substrate (substrate/AuNWs) or on a graphene-coated Au film (substrate/Au film/graphene/AuNWs). The results have shown that by optimizing the parameters of...

Morphological, structural, electrical, and piezoelectric analysis of hydrothermally grown ZnO nanowires on various substrates

Abderrahmane Hamdi, Ahmad Hamieh, Mervat Alamri, Karim Dogheche, M.M. Saj Mohan, Rachel Desfeux, Denis Remiens, El Hadj Dogheche

In this present work, we have successfully fabricated a piezoelectric structure based on ZnO nanowires (ZnO NWs) using a simple, low cost and environmentally friendly hydrothermal method. This structure forms the basis to fabricate vertically integrated nanogenerator device. This paper attempts to...

Knowledge-based tensor subspace analysis system for kinship verification

I. Serraoui, O. Laiadi, A. Ouamane, F. Dornaika, Abdelmalik Taleb-Ahmed

Most existing automatic kinship verification methods focus on learning the optimal distance metrics between family members. However, learning facial features and kinship features simultaneously may cause the proposed models to be too weak. In this work, we explore the possibility of bridging this...
