Uniform boundary observability with Legendre-Galerkin formulations of the 1-D wave equation

Autor: Ludovick Gagnon, José M. Urquiza

Publikováno v: Evolution Equations & Control Theory. 10:129-153

We study the boundary observability of the 1-D homogeneous wave equation when using a Legendre-Galerkin semi-discretization method. It is already known that spurious high frequencies are responsible for its lack of uniformity with respect to the disc

Penalty: finite element approximation of Stokes equations with slip boundary conditions

Autor: José M. Urquiza, Ibrahima Dione

Publikováno v: Numerische Mathematik. 129:587-610

We consider the finite element approximation of the stationary Stokes equations with slip boundary conditions on a domain with a smooth curved boundary. The slip boundary condition is imposed weakly with the penalty method on polygonal domains approa

Finite element approximations of the Lamé system with penalized ideal contact boundary conditions

Autor: Ibrahima Dione, José M. Urquiza

Publikováno v: Applied Mathematics and Computation. 223:115-126

We consider finite element approximations of the Lame system of elasticity with ideal contact boundary conditions imposed with the penalty method. For a polygonal or polyhedral boundary, we prove convergence estimates in terms of both the penalty and

Self-thinning dynamics in experimental scallop populations

Publikováno v: Aquaculture International. 21:539-551

Self-thinning-related mortality has been encountered in extensively cultured scallop populations. Here we report an experiment aimed at studying actual population dynamics of scallops undergoing self-thinning and develop a model of the process. Scall

Common variable immunodeficiency (CVID), the most frequent primary immunodeficiency characterized by loss of B-cell function, depends partly on genetic defects, and epigenetic changes are thought to contribute to its aetiology. Here we perform a high
