Feedback stabilization of a simplified model of fluid-structure interaction on a tree
Kaïs Ammari, Farhat Shel, Muthusamy Vanninathan
In this paper we study the dynamic feedback stability for a simplified model of fluid-structure interaction on a tree. We prove that, under some conditions, the energy of the solut…
Stability of a tree-shaped network of strings and beams
Kaïs Ammari, Farhat Shel
In this paper we study the stability of a tree-shaped network of elastic strings and beams with some feedbacks at the ends. The whole system is asymptotically stable. Moreover, the…
Determining the potential in a wave equation without a geometric condition. Extension to the heat equation
Kais Ammari, Mourad Choulli, Faouzi Triki
We prove a logarithmic stability estimate for the inverse problem of determining the potential in a wave equation from boundary measurements obtained by varying the first component…
A remark on observability of the wave equation with moving boundary
K. Ammari, A. Bchatnia, K. El Mufti
We deal with the wave equation with assigned moving boundary () upon which Dirichlet or mixed boundary conditions are specified, here is assumed to move slower tha…
Logarithmic stability in determining a boundary coefficient in an ibvp for the wave equation
Kais Ammari, Mourad Choulli
In [2] we introduced a method combining together an observability inequality and a spectral decomposition to get a logarithmic stability estimate for the inverse problem of determi…
Determining a boundary coefficient in a dissipative wave equation: Uniqueness and directional lipschitz stability
Mourad Choulli, Kaïs Ammari
We are concerned with the problem of determining the damping boundary coefficient appearing in a dissipative wave equation from a single boundary measurement. We prove that the uni…
