Exponential stability and exact controllability of a system of coupled wave equations by second-order terms (via Laplacian) with only one non-smooth local damping

Mohammad Akil, Zayd Hajjej

The purpose of this work is to investigate the exponential stability of a second-order coupled wave equations by Laplacian with one locally internal viscous damping. The strong stability is established by combining a unique con- tinuation result and a Carleman estimate. Besides, the exponential...

A N-dimensional elastic$$\backslash $$viscoelastic transmission problem with Kelvin–Voigt damping and non smooth coefficient at the interface

Mohammad Akil, Ibtissam Issa, Ali Wehbe

We investigate the stabilization of a multidimensional system of coupled wave equations with only one Kelvin–Voigt damping. Using a unique continuation result based on a Carleman estimate and a general criteria of Arendt–Batty, we prove the strong stability of the system in the absence of the...

Stability results on the Kirchhoff plate equation with delay terms on the dynamical boundary controls

Mohammad Akil, Haidar Badawi, Serge Nicaise, Ali Wehbe

In this paper, we consider the Kirchhoff plate equation with delay terms on the dynam- ical boundary controls. We prove its well-posedness, strong stability, non-exponential stability, and polynomial stability under a multiplier geometric control condition.

Minimal δ(2)-ideal Lagrangian submanifolds and the quaternionic projective space

Kristof Dekimpe, Joeri van der Veken, Luc Vrancken

We construct an explicit map from a generic minimal δ(2)-ideal Lagrangian submanifold of Cn to the quaternionic projective space HPn−1, whose image is either a point or a minimal totally complex surface. A stronger result is obtained for n=3, since the above mentioned map then provides a one-to-one...

Hyperbolic Radial Spanning Tree

David Coupier, Lucas Flammant, Viet Chi Tran

We define and analyze an extension to the d-dimensional hyperbolic space of the Radial Spanning Tree (RST) introduced by Baccelli and Bordenave in the two-dimensional Euclidean space (2007). In particular, we will focus on the description of the infinite branches of the tree. The properties of the...

Insight into the interactions of albumin with TiO2 nanomaterials and calcium phosphate-based biomaterials by kinetic adsorption and spectroscopic studies

Ina Erceg, Vida Strasser, Nicolas Somers, Marta Jurković, Jasminka Kontrec, Damir Kralj, Rinea Barbir, Ivana Vinković Vrček, Marie Lasgorceix, Anne Leriche, Maja Dutour Sikirić

Among key factors determining the fate of biomaterials in vivo are their interactions with blood serum proteins, which can lead to either successful integration or rejection/encapsulation. Although there are a number of studies investigating the interactions between proteins and bioimplants,...

Well-posedness and polynomial energy decay rate of a transmission problem for Rayleigh beam model with heat conduction

Mohammad Akil, Mouhammad Ghader, Zayd Hajjej, Mohamad Ali Sammoury

In this paper, we investigate the stability of the transmission problem for Rayleigh beam model with heat conduction. First, we reformulate our system into an evolution equation and prove our problem’s well-posedness. Next, we demonstrate the resolvent of the operator is compact in the energy space...

Combination of indirect stereolithography and gel casting methods to shape ceramic dental crowns

Pierre Grimaud, Fabrice Petit, Laurent Boilet, Marie Lasgorceix, Florian Jean, Anne Leriche, Pascal Laurent, Philippe Champagne

Dental crowns are among the modern tools used in dentistry to restore physiological function such as phonation or mastication. They are currently mainly manufactured by machining pre-sintered disk but this technique has some drawbacks such as risks of damage to the part or some geometric...

Macroporous biphasic calcium phosphate materials for bone substitute applications

Danielle Madefo Tchuyassi, Marie Lasgorceix, Stephane Hocquet

Ceramic stereolithography (SLA) is a 3D printing technology that offers one of the highest resolutions currently available. SLA is particularly suitable for the design of bone substitutes which must have a very complex geometric shape and an interconnected macroporous internal structure, ideally...
