Numerical Approach Based on the Composition of One-Step Time-Integration Schemes For Highly Deformable Interfaces

In this work, we propose a numerical approach for simulations of large deformations of interfaces in a level set framework. To obtain a fast and viable numerical solution in both time and space, temporal discretization is based on the composition of

A Finite Element Approach For Modeling Biomembranes In Incompressible Power-Law Flow

Autor: Laadhari, Aymen, Deeb, Ahmad

We present a numerical method to model the dynamics of inextensible biomembranes in a quasi-Newtonian incompressible flow, which better describes hemorheology in the small vasculature. We consider a level set model for the fluid-membrane coupling, wh

Nonexistence of global weak solutions to semilinear wave equations involving time-dependent structural damping terms

Autor: Kirane, Mokhtar, Fino, Ahmad, Kerbal, Sebti, Laadhari, Aymen

We consider a semilinear wave equation involving a time-dependent structural damping term of the form $\displaystyle\frac{1}{{(1+t)}^{\beta}}(-\Delta)^{\sigma/2} u_t$. Our results show the influence of the parameters $\beta,\sigma$ on the nonexistenc

Modélisation numérique de la dynamique des globules rouges par la méthode des fonctions de niveau

Autor: Laadhari, Aymen

Ce travail, à l'interface entre les mathématiques appliquées et la physique, s'articule autour de la modélisation numérique des vésicules biologiques, un modéle pour les globules rouges du sang. Pour cela, le modéle de Canham et Helfrich est
