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...

Well-posedness and stability results for nonlinear abstract evolution equations with time delays

Serge Nicaise, Cristina Pignotti

We consider abstract evolution equations with a nonlinear term depending on the state and on delayed states. We show that, if the C0 -semigroup describing the linear part of the model is exponentially stable, then the whole system retains this property under some Lipschitz continuity assumptions on...

Estimates of oscillatory integrals with stationary phase and singular amplitude: Applications to propagation features for dispersive equations

Florent Dewez

In this paper, we study time‐asymptotic propagation phenomena for a class of dispersive equations on the line by exploiting precise estimates of oscillatory integrals. We propose first an extension of the van der Corput Lemma to the case of phases which may have a stationary point of real order and...

Lagrangian submanifolds in the homogeneous nearly Kähler S3×S3

Bart Dioos, Luc Vrancken, Xianfeng Wang

In this paper, we investigate Lagrangian submanifolds in the homogeneous nearly Kähler S3×S3. We introduce and make use of a triplet of angle functions to describe the geometry of a Lagrangian submanifold in S3×S3. We construct a new example of a flat Lagrangian torus and give a complete...

Crystal structures of Na1.85Mg1.85In1.15(PO4)3 and Ag1 .69In1.31(PO4)3 with alluaudite-type structure

Ahmed Ould Saleck, Abderrazzak Assani, Mohamed Saadi, Cyrille Mercier, Claudine Follet, Lahcen El Ammari

Single crystals of two new phosphates, sodium magnesium indium(III) tris­(orthophosphate) and silver magnesium indium(III) tris­(orthophosphate), were obtained from solid-state reactions. The two phosphates are isotypic and exhibit alluaudite-type structures. They are characterized by a cationic...
