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…

Usage des points massiques et des courbes de Bézier pour la modélisation des cubiques

Karine Serier, Jean-Paul Becar, Lionel Garnier

Cet article étend l'étude des points singuliers et des points d'inflexion des courbes rationnelles cubiques en s'ins-pirant de la méthode proposée par M. Sakai dans le cadre des points massiques. L'intérêt des points massiques permet de représenter une boucle c'est à dire…

Design and Construction of a Multifunction Piezoelectric Transformer

Adil Eddiai, Mounir Meddad, Mohamed Rguiti, Aïda Chérif, Christian Courtois

In recent years, piezoelectric materials have particularly found advantageous field of application in electrical energy’s conversion. Especially, the piezoelectric transformers are becoming more and more usable in electrical devices owing to several advantages such as small size, high efficiency,…

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…

New System to Harvest Road Energy Using Piezoelectric Polymers

Chouaib Ennawaoui, Houda Lifi, Abdelowahed Hajjaji, Az-Eddine Azim, Abdessamad Elballouti, Mohamed Rguiti

Green energy is regarded as an essential element for energy production, sustainable development, technological, industrial, and governmental innovations in the world. An increase in the green energy consumption often provides a positive impact on economic growth and social development. A great deal…

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…

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…

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…
