Geography of bilinearized Legendrian contact homology

Frédéric Bourgeois, Damien Galant

We study the geography of bilinearized Legendrian contact homology for closed, connected Legendrian submanifolds with vanishing Maslov class in 1-jet spaces. We show that this invariant detects whether the two augmentations used to define it are DGA homotopic or not. We describe a collection of…

Performance of a dual piezoceramic cantilever for low frequency energy harvesting applications: modeling and experiment verification

Madiha Yessari, Najoua Fangachi, Imane Salhi, Mohamed Rguiti, Abdelowahed Hajjaji

Vibration-based energy harvesting is a growing field for generating low-power electricity to use in wireless electronic devices. These applications are usually in an environment of abundant low frequency vibration, which can be collected through an appropriate energy conversion structure. However,…

Un système local de prévision et alerte des submersions côtières centré sur les besoins des utilisateurs et utilisant des techniques de métamodélisation

Déborah Idier, Axel Aurouet, François Bachoc, Audrey Baills, José Daniel Betancourt, Fabrice Gamboa, Thierry Klein, Sylvestre Le Roy, Andrés F. López-Lopera, Jessie Louisor, Rodrigo Pedreros, Jérémy Rohmer, Alexandre Thibault

Il est désormais possible de modéliser correctement les inondations côtières. Néanmoins, ces modèles sont trop coûteux en temps de calcul pour permettre leur utilisation pour la prévision-alerte. Ce travail vise à développer et à tester une méthode rapide et robuste, capable de prévoir des…

STUDY OF THE FIRST BOULOGNE-SUR-MER CEMENTS USED FOR A HISTORIC AQUEDUCT FROM THE 19TH CENTURY

Marwa Jebbawy, Vincent Thiéry, Myriam Bouichou, Elisabeth Marie-Victoire, Catherine Davy, Laurent Izoret, Cyrille Albert-Mercier, Myriam Moreau

Natural and Roman cements are generally considered as the first binders of the 19th century concrete but their widespread usage was short-lived as they were quickly replaced by artificial cements (Portland), still the most important and predominant today. The Boulogne-Sur-Mer area in the North of…

Hermite interpolation by planar cubic-like ATPH, Interpolation de Hermite par des courbes ATPH pseudo-cubiques planes

Thierry Bay, Isabelle Cattiaux-Huillard, Laura Saini

This paper deals with the construction of the Algebraic Trigonometric Pythagorean Hodograph (ATPH) cubic-like Hermite interpolant. A characterization of solutions according to the tangents at both ends and a global free shape parameter α is performed. Since this degree of freedom can be used for…

Influence of calcium substitution on structural, morphological and electrical conductivity properties of La1- xCaxNi0.5Ti0.5O3 (x = 0.0, x = 0.2) compounds for energy storage devices

Sirine Gharbi, Ahmadou Ly, Essebti Dhahri, Régis Barillé, Driss Lahem, Marc Debliquy, Mohamed Rguiti

This paper explores the effect of calcium insertion on the physicochemical properties of La1-xCaxNi0.5Ti0.5O3 (x = 0.0 (LNTO), x = 0.2 (LCNTO)) compounds fabricated by the sol–gel process. The samples crystallize in an orthorhombic distorted structure with the Pnma space group. The purity and…
