A preconditioning method for the finite element stiffness matrix is given in this paper. The triangulation is refined in a subregion; the preconditioning process is composed of resolution of two ...
This paper concerns the reconstruction of a penetrable obstacle embedded in a waveguide using the scattered data due to point sources, which is formulated as an optimization problem. We propose a fast ...
