Le Contrôle-Santé Intégré (CSI) réduit les besoins d’inspections humaines grâce à une surveillance automatisée, réduit les coûts de maintenance grâce à la détection précoce des anomalies avant qu’elles ne dégénèrent et améliore la sécurité ainsi que la fiabilité des services. L’objectif de cette…, Structural Health Monitoring (SHM) reduces human inspection requirements through automated monitoring, reduces maintenance costs by early detection of defects before they escalate, and improves safety and reliability of services. The work presented in this thesis aims to design a wireless…

Stabilisation d’un laser Brillouin fibré non résonant pour la pompe : application à la génération de porteuse opto-RF ultra-pure

Gwennaël Danion, Ludovic Frein, Denis Bacquet, Gregoire Pillet, Stéphanie Molin, Loïc Morvan, Guillaume Ducournau, Marc Vallet, Pascal Szriftgiser, Mehdi Alouini

Nous présentons une nouvelle méthode de stabilisation d’un laser Brillouin fibré de faible largeur de raie dont la pompe est non résonante pour la cavité fibrée. Les sauts de mode sont supprimés au moyen d'une boucle à verrouillage de phase qui verrouille l’écart en fréquence entre l’onde de…

Understanding fluid transport through claystones from their 3D nanoscopic pore network

Yang Song, Catherine A. Davy, P. Bertier, David Troadec

This paper investigates the complex and nanoscopic pore network of claystones, after their retrieval from the geological layer, and their further conditioning and drying, as it is usually done to assess their fluid permeability (i.e. their transport properties). Following the leading research of…

Reverberation of flexural waves scattered by a local heterogeneity in a plate

Hossep Achdjian, Emmanuel Moulin, Farouk Benmeddour, Jamal Assaad, Lucie Dupont, Lynda Chehami

A statistical model is proposed to relate the scattering properties of a local heterogeneity in a plate to the statistical properties of scattered and reverberated flexural waves. The contribution of the heterogeneity is isolated through the computation of differential signals consisting of a…

Computation of correlation and cumulant 4 under FPGA architecture

Lamyae Maatougui, Laila Sakkila, Rahmad Sadli, Atika Rivenq

Higher Order Statistics are used in digital signal processing as a powerful analytical tool for the analysis of signals and systems. These statistics are very useful in problems where either non-Gaussianity or non-minimum phase. The computation of the fourth-order cross moments from incoming time-…

Polynomial approach for modeling a piezoelectric disc resonator partially covered with electrodes

L. Elmaimouni, Jean-Etienne Lefebvre, F.E. Ratolojanahary, J.G. Yu, P.M. Rabotovao, I. Naciri, Tadeusz Gryba, Mohamed Rguiti

The frequency spectrum of a partially metallized piezoelectric disc resonator was studied using Legendre polynomials. The formulation, based on three-dimensional equations of linear elasticity, takes into account the high contrast between the electroded and non-electroded regions. The mechanical…

Achievable rates for additive isotropic α-stable noise channels

Malcolm Egan, Mauro Lopes de Freitas, Laurent Clavier, Alban Goupil, Gareth W. Peters, Nourddine Azzaoui

Impulsive noise arises in many communication systems-ranging from wireless to molecular-and is often modeled via the alpha-stable distribution. In this paper, we investigate properties of the capacity of complex isotropic alpha-stable noise channels, which can arise in the context of wireless…

Gas Breakthrough Pressure (GBP) through Claystones: Correlation with FIB/SEM Imaging of the Pore Volume

Yang Song, Catherine A. Davy, David Troadec

This contribution uses six claystone samples imaged by FIB/SEM (Focused Ion Beam/Scanning Electron Microscopy), within micrometric volumes located in the clay matrix; their 3D connected pore network is identified down to 17-22 nm pore size. All samples are gently dried to minimize damage, and…

On-body calibration and measurements using personal radiofrequency exposimeters in indoor diffuse and specular environments

Reza Aminzadeh, Arno Thielens, Aliou Bamba, Lamine Kone, Davy Gaillot, M. Lienard, Luc Martens, Wout Joseph

For the first time, response of personal exposimeters (PEMs) is studied under diffuse field exposure in indoor environments. To this aim, both numerical simulations, using finite-difference time-domain method, and calibration measurements were performed in the range of 880–5875 MHz covering 10…
