Journal ArticleDOI
The boundary-element method for the determination of a heat source dependent on one variable
Adrian Farcas,Daniel Lesnic +1 more
TL;DR: In this article, the inverse problem of determining a heat source in the parabolic heat equation using the usual conditions of the direct problem and a supplementary condition, called an overdetermination, is investigated.
Journal ArticleDOI
A survey of applications of the MFS to inverse problems
TL;DR: The method of fundamental solutions (MFS) is a relatively new method for the numerical solution of boundary value problems and initial/boundary value problems governed by certain partial differential equations as discussed by the authors.
Journal ArticleDOI
The Cauchy problem for Laplace’s equation via the conjugate gradient method
Dinh Nho Hào,Daniel Lesnic +1 more
TL;DR: In this article, a variational formulation of the Cauchy problem for the Laplace equation is studied and an efficient conjugate gradient method based on an optimal-order stopping criterion is presented together with its numerical implementation.
Journal ArticleDOI
Determination of a spacewise dependent heat source
Tomas Johansson,Daniel Lesnic +1 more
TL;DR: In this article, the authors investigated the inverse problem of determining a spacewise dependent heat source in the parabolic heat equation using the usual conditions of the direct problem and information from a supplementary temperature measurement at a given single instant of time.
Journal ArticleDOI
The method of fundamental solutions for the Cauchy problem associated with two-dimensional Helmholtz-type equations
Liviu Marin,Daniel Lesnic +1 more
TL;DR: In this article, the application of the method of fundamental solutions to the Cauchy problem associated with two-dimensional Helmholtz-type equations is investigated, where the resulting system of linear algebraic equations is ill-conditioned and therefore its solution is regularized by employing the first-order Tikhonov functional, while the choice of the regularization parameter is based on the L-curve method.
