Sublinearity of the number of semi-infinite branches for geometric random trees

David Coupier

The present paper addresses the following question: for a geometric random tree in R-2, how many semi-infinite branches cross the circle C-r centered at the origin and with a large radius r? We develop a method ensuring that the expectation of the number X-r of these semi-infinite branches is o (r...

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...

Lagrangian submanifolds in the homogeneous nearly Kahler S3×S3 with constant sectional curvature

Luc Vrancken

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...

HOW ROBOTICS VISION AND COMPUTER VISION IMPROVE INTERDISCIPLINARITY

Jean-Paul Becar, Jean-Charles Canonne, Laurent Vermeiren, Abdelmalik Taleb-Ahmed

Since a decade, the academic syllabus for bachelors in Electrical Engineering domain is reserving a wide area for projects. The projects represent about ten percent of the final marks for the diploma validation after two years courses in theoretical, technical domains and its applications. The...

Processing of PVDF-based electroactive/ferroelectric films: importance of PMMA and cooling rate from the melt state on the crystallization of PVDF beta-crystals

Alexandre de Neef, Cédric Samuel, Grégory Stoclet, Mohamed Rguiti, Christian Courtois, Philippe Dubois, Jérémie Soulestin, Jean-Marie Raquez

Poly(vinylidene difluoride) (PVDF) displays attractive ferroelectric/piezoelectric properties and its polar β-crystals are specifically targeted for achieving electroactive applications. However, their direct crystallization from the melt state represents a challenging task that has never been...

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 -semigroup describing the linear part of the model is exponentially stable, then the whole system retains this property under some Lipschitz continuity assumptions on...

A prescribed anisotropic mean curvature equation modeling the corneal shape: A paradigm of nonlinear analysis

Chiara Corsato, Colette De Coster, Franco Obersnel, Pierpaolo Omari, Alessandro Soranzo

In this paper we survey, complete and refine some recent results concerning the Dirichlet problem for the prescribed anisotropic mean curvature equation (Equation Presented), in a bounded Lipschitz domain Ω ⊂ RN, with a, b > 0 parameters. This equation appears in the description of the geometry...
