Ultrasonic imaging of contact defects under low frequency loading, Imagerie ultrasonore de défaut de contact sous sollicitations basse fréquence

Marina Terzi

In structural health monitoring, acoustic methods without use of a reference intact sample are nowadays of great interest due to variability of environmental and operational conditions. This thesis presents an acoustic reference-free method for detecting and localizing defects in thin plates. The…, Le contrôle-qualité de matériaux par méthodes acoustiques sans référence suscite aujourd’hui un grand intérêt en contrôle santé intégré (CSI) au vu de la variabilité des conditions environnementales et opérationnelles. Dans ce manuscrit, nous proposons une méthode de détection synchrone/non…

Investigation of the effect of Sr-substitution on the structural, morphological, dielectric, and energy storage properties of BaTiO3-based perovskite ceramics

Rafik Moussi, Amira Bougoffa, Abdessalem Trabelsi, Essebti Dhahri, M.P.F. Graça, M.A. Valente, R. Barille, Mohamed Rguiti

In this work, Ba1-xSrxTiO3 (x = 0 and x = 0.3) samples, abbreviated respectively BT and BST, have been prepared by conventional solid state reaction. The pure phase formation and crystal structure were approved by X-ray powder diffraction analysis. The morphology of these samples were inspected by…

Efficient Hybrid Algorithm Solution for Optimal Reactive Power Flow Using the Sensitive Bus Approach

Zahir Sahli, Abdellatif Hamouda, Samir Sayah, Damien Trentesaux, Abdelghani Bekrar

This paper presents the design and application of an efficient hybrid algorithm for solving the Optimal Reactive Power Flow (ORPF) problem. The ORPF is formulated as a nonlinear constrained optimization problem where the active power losses must be minimized. The proposed approach is based on the…

The contribution of static and dynamic tests to the assessment of visuospatial abilities among adult males

Hatem Ben Mahfoudh, Bachir Zoudji, Antonio Pinti

Visuospatial abilities (VSA) reflect individuals' aptitude to deal with visual elements presented in space. VSA are considered to involve different abilities that can be measured with various tests. However, the number and types of tests to be considered are still being debated, especially for…

Stability results for some hyperbolic systems with direct or indirect local dampings, Résultats de stabilité pour certains systèmes hyperboliques avec amortissements locaux directs ou indirects

Haidar Badawi

In this thesis, we study the indirect stability of some coupled systems with different kinds of local discontinuous dampings. We also study the stability and the instability results of the Kirchhoff plate equation with delay terms on the boundary or dynamical boundary controls. First, we…, Dans cette thèse, nous étudions la stabilité indirecte de certains systèmes couplés avec différents types d'amortissements locaux discontinus. Nous étudions également des résultats de stabilité et d'instabilité de l'équation des plaques de Kirchhoff avec des termes de retard à la…

A techno-economic analysis of small-scale trigenerative compressed air energy storage system

Mohamad Cheayb, Mylène Marin Gallego, Mohand Tazerout, Sébastien Poncet

New advances in CAES have demonstrated the benefits of trigenerative concept (T-CAES), especially in off-grid sites. Many studies focused on thermodynamic optimization of design and operation parameters of the system. They underlined the importance of extending research objectives to techno-…

CFD modelling of the flow in zero-secondary flow ejectors: a sensitivity analysis to numerical parameters

Ala Bouhanguel, Valérie Lepiller, Philippe Desevaux

This paper presents a sensitivity study of various CFD simulation parameters conducted in the case of a 2D axisymmetric ejector operating without induced flow. The influence of numerical parameters (solver, discretisation scheme, mesh and turbulence model) is investigated by comparing the various…

The coupled heat Maxwell equations with temperature-dependent permittivity

Tonia-Maria Alam, Luc Paquet

We consider the heat equation coupled with the Maxwell system, the Ampère- Maxwell equation being coupled to the heat equation by the permittivity, which depends on the temperature due to thermal agitation, and the heat equation being coupled to the Maxwell system by the volumic heat source term.…
