In previous studies, the efficiency of the Half-Sweep Multigrid method has been shown to be very fast as compared with the standard Multigrid method. This is due to its ability to reduce computational complexity of the standard method. In this paper, the primary goal is to purpose the Half-Sweep Algebraic Multigrid (HSAMG) method using the HSCN finite(More)
BACKGROUND We conducted a retrospective cohort study to evaluate the clinical manifestations, laboratory findings, complications and treatment of brucellosis in the State of Qatar. METHODS The medical records of patients in Hamad Medical Corporation, Doha, Qatar were reviewed from January 2000 to December 2006. History, various socio-demographic features,(More)
The rotated fourth order iterative algorithm of O(h 4) accuracy applied to linear system arising from the discretization of two dimensional Poisson problem was introduced by Othman, et al., 2001 and it was shown to be the fastest as compared to the standard fourth order iterative algorithm, see Gupta, 1984. While the parallel standard fourth order iterative(More)
