Processing and Characterization of Polyamide/Lead Zirconium Titanate Composite for Sensing and Actuating Applications

Rida Farhan, Mohamed Rguiti, Adil Eddiai, M’hammed Mazroui, Mounir Meddad, Christian Courtois

Piezoelectric composites made from at low percentage of lead zirconium titanate (PZT) particles as filler and a polyamide-6 as the matrix were prepared by solutions casting and studied for their piezoelectric, dielectric, mechanical and structural properties. It was found that the incorporation of…

Effect of fillers size on the dielectric and piezoelectric characteristics of a piezoelectric composite

Sarah Aboubakr, Abdelowahed Hajjaji, Mohamed Rguiti, Khalil Benkhouja, Christian Courtois, Y. Boughaleb

Recent trends in electromechanical conversion using alternative materials, have demonstrated the advantages of using piezoelectric composites for energy generation. There have been several papers on ceramic/polymer composites in which the fillers have high piezoelectric constant. Basically, the…

Algebraic-trigonometric Pythagorean hodograph curves for solving planar and spatial interpolation problems and their use for visualizing dental information within 3D tomographic volumes, Les courbes algébriques trigonométriques à hodographe pythagorien pour résoudre des problèmes d'interpolation deux et trois-dimensionnels et leur utilisation pour visualiser les informations dentaires dans des volumes tomographiques 3D

Cindy González

Interpolation problems have been widely studied in Computer Aided Geometric Design (CAGD). They consist in the construction of curves and surfaces that pass exactly through a given data set, such as point clouds, tangents, curvatures, lines/planes, etc. In general, these curves and surfaces are…, Les problèmes d'interpolation ont été largement étudiés dans la Conception Géométrique Assistée par Ordinateur. Ces problèmes consistent en la construction de courbes et de surfaces qui passent exactement par un ensemble de données. Dans ce cadre, l'objectif principal de cette thèse est…

Dental information along curved slices

Cindy González, Ma. I. Pérez, Marianela Lentini, D. Ríos, Gudrun Albrecht, Marco Paluszny

Within the family of ruled surfaces, the developable curved slices have a special property: they may be flattened without deformation. In this paper we introduce a technique to visualize information encoded in a 3D tomographic volume along such a curved slice. This property is deemed useful in…

Influence of the w/c ratio on the hydration process of a magnesium phosphate cement and on its retardation by boric acid

Hugo Lahalle, Céline Cau Dit Coumes, Cyrille Mercier, David Lambertin, Céline Cannes, Sylvie Delpech, sandrine Gauffinet

Magnesium potassium phosphate cements (MKPCs) are prepared using calcined magnesia (MgO) and an acidic solution of potassium dihydrogen phosphate (KH2PO4). Their fast setting and high heat of hydration can be problematic when large volumes of materials are produced. Boric acid (B(OH)(3)) is thus…

Stabilization of a Drude/Vacuum Model

Serge Nicaise

We analyze the stability of a dispersive medium immersed in vacuum (with Silver–Müller boundary condition in the exterior boundary) or vice versa. The dispersive medium model corresponds to the coupling between Maxwell’s system and a first order ordinary differential equation (of parabolic type).…

Properties of the nearly kähler S3×S3

Marilena Moruz, Luc Vrancken

We show how the metric, the almost complex structure and the almost product structure of the homogeneous nearly Kahler S3 × S3 can be recovered from a submersion π : S3 × S3 × S3 → S3 × S3. On S3 × S3 × S3 we have the maps obtained either by changing two coordinates, or by cyclic permutations. We…
