Additive Schwarz preconditioner for the finite volume element discretization of symmetric elliptic problems
Marcinkowski, Leszek; Rahman, Talal; Loneland, Atle; Valdman, Jan (Peer reviewed; Journal article, 2015-09-25)A symmetric and a nonsymmetric variant of the additive Schwarz preconditioner are proposed for the solution of a class of finite volume element discretization of the symmetric elliptic problem in two dimensions, with large ... -
Sparse-Data Based 3D Surface Reconstruction for Cartoon and Map
Wu, Bin; Rahman, Talal; Tai, Xue-Cheng (Chapter, 2018)A model combining the first-order and the second-order variational regularizations for the purpose of 3D surface reconstruction based on 2D sparse data is proposed. The model includes a hybrid fidelity constraint which ...
