This communication describes an efficient implementation of the non-local Dirichlet-to-Neumann (DtN) radiation boundary condition which arises in the solution of exterior problems in acoustics. Exterior problems in acoustics involve unbounded fluid domains whose finite element solution requires the
## Abstract We consider an inverse problem to recover a spaceβ and timeβdependent relaxation function of heat flux in a threeβdimensional body on the basis of the restriction of the DirichletβtoβNeumann operator of the related equation of heat flow onto a set of Dirichlet data of the form of a prod
