In 1991 AD Gunawardena et al. reported that the convergence rate of the Gauss-Seidel method
with a preconditioning matrix I + S is superior to that of the basic iterative method. In this …

We extend the modified Gauss-Seidel method introduced by AD Gunawardena et al. Some
numerical examples show that our method is able to improve the rate of convergence …

Several preconditioned iterative methods reported in the literature have been used for
improving the convergence rate of the Gauss–Seidel method. In this article, on the basis of …

It has recently been reported that the convergence of the preconditioned Gauss-Seidel method
which uses a matrix of the type (I + U) as a preconditioner is faster than the basic iterative …

We provide an algorithmic characterization of H-matrices. When A is an H-matrix, this algorithm
determines a positive diagonal matrix D such that AD is strictly row diagonally dominant. …

In 1991, Gunawardena et al. (Linear Algebra Appl. 154–156 (1991) 123) have reported the
modified Gauss–Seidel method with a preconditioner (I+S). In this article, we propose to use …

In recent years, a number of preconditioners have been applied to linear systems [AD
Gunawardena, SK Jain, L. Snyder, Modified iterative methods for consistent linear systems, Linear …

As well know, a bicycle is a high efficiency vehicle and is suitable for aging society in the future.
In the practical use, however, the bicycle is not always stable and the motion stabilization …

The anti-xerostomia effects of muscarinic agonists (cholinomimetics) are reviewed.
Cevimeline (cevimeline monohydrochloride hemihydrate) is a novel muscarinic agonist that …

A micro-level method of finance called tanomoshi, a type of lending circle, was used in Japan
whereby people acting cooperatively could realize a set amount of capital. For example, …
