Parallel normalized preconditioned conjugate gradient type methods based on normalized approximate finite element inverse matrix techniques are investigated for the efficient solution of sparse linear systems. Application of the proposed methods on a three dimensional boundary value problems is discussed and numerical results are given. The parallel implementation of the normalized precondition...

We developed a fast numerical method for complex symmetric shifted linear systems, which is motivated by the quantum-mechanical (electronicstructure) theory in nanoscale materials. The method is named shifted Conjugate Orthogonal Conjugate Gradient (shifted COCG) method. The formulation is given and several numerical aspects are discussed.

Treatment methods for breast cancer are not specific and each one has its own drawbacks. For this reason, scientists are seeking ways in which specifically affect cancer cells. Photothermal therapy is a method that uses near-infrared (NIR) laser energy to create sufficient heat to destroy cancer cells. In this study, the photothermal effect of gold nanorods (GNRs) was investigated for breast ca...

2 [email protected] ________________________________________________________________________________ ABSTRACT We propose a new algorithm for removing a fast motion blur from an image. The term "iterative met hod" refers to a wide range of techniques which use successive approximations to obtain more accurate solutions .In this paper an attempt to solve systems of linear equations of the form ...

The solution of large sparse systems of linear equations is one of the most compu-tationally intensive parts of nite element simulations. In order to solve these systems of linear equations, we have implemented a parallel conjugate gradient solver on the SPMD-programmable MUSIC-system. We outline the conjugate gradient method, give a formal speciication in Maple, and describe a data-parallel pr...
