Stabilization of a system of anisotropic thermoelasticity by nonlinear boundary and internal feedbacks

We consider the stabilization of an anisotropic thermoelasticity system with a natural Neumann boundary condition on part of the boundary and combined nonlinear internal and boundary feedbacks. We then give an answer to a problem raised by Liu and Zuazua.

Rosai Dorfman disease diagnosed by fine‐needle aspiration cytology in a young man with HIV infection

RDD (Rosai Dorfman disease) is a rare and benign histiocytic proliferative disorder of unknown etiology. FNAC (Fine‐needle aspiration cytology) is a useful and reliable tool for the diagnosis of RDD, and as such, biopsy is avoidable.

Estimates Related to the Extended Spectral Control of the Wave Equation

In this work, we show through a numerical approach the extended spectral controllability of the wave equation over a portion of a regular domain, and that the spectrum obtained is quasi-symmetrical. Numerical simulations also verify the analytical estimates demonstrated in Niane and al.

Sur la controlabilité exacte de l’equation des plaques vibrantes

Is it possible to cancel singularities in a domain with corners and cracks

and the graphic illustrations relating to this spectral controllability were done.

Contrôlabilité exacte de l’équation des ondes dans des espaces de Sobolev non réguliers pour un ouvert polygonal

We define, for the trace of solution of vibrating plates equation, norms with initial conditions in no regular spaces. Then, we give the corresponding exact controllability results.
