Abstract: |
This paper presents a new improved meshless numerical scheme to solve the nonhomogeneous backward heat conduction problems. Fundamental solutions of heat equations and radial basis functions of both and are employed to obtain a numerical ill-conditioned, the Tikhonov regularization method is adopted to solve the resulting system of linear equations. Therefore, generalized cross-validation (GCV) method is used to choose a regularization parameter. The accuracy and efficiency of our proposed method is illustrated by several typical 1-D and 2-D numerical examples. |
