W I T H the discovery of linkage and crossing over, geneticists acquired a technique for estimating the physical distances between genes on the chromosome. From the first, however, the accuracy of linkage maps has been viewed with reservation. Too many extraneous factors, including temperature (PLOUGH 1917) and maternal age (BRIDGES 1927), were shown to modify linkage values. Furthermore, both ...

As the development of the PSOR method (a point parallel SOR method by mesh domain partitioning proposed in [SIAM J. Sci. Comput., 20 (1999), pp. 2261–2281], this paper introduces a new mesh domain partition and ordering (the multitype partition and ordering), and proposes a new block parallel SOR (BPSOR) method for numerically solving 2-dimensional (2D) or three-dimensional (3D) elliptic bounda...

This paper describes a method for the numerical solution of linear systems of equations. The method is a two-parameter generalization of the Successive Overrelaxation (SOR) method such that when the two parameters involved are equal it coincides with the SOR method. Finally, a numerical example is given to show the superiority of the new method.

The study of the problem of Magneto Hydrodynamic viscous flow due to a shrinking sheet of Micropolar fluids has been solved numerically by using SOR method with Simpson (1/3) Rule. The similarity transformations have been used to reduce the highly nonlinear partial differential equations of motion to ordinary differential equations. The resulting equations are then integrated by using appropria...

OBJECTIVES The National Social Life, Health, and Aging Project (NSHAP) data contain multiple indicators of social connectedness, social participation, social support, and loneliness among older adults. We suggest that these indicators can be combined to measure two aspects of social isolation: social disconnectedness (i.e., physical separation from others) and perceived isolation (i.e., feeling...

For the augmented system of linear equations, Zhang and Lu (2008) recently studied the generalized symmetric SOR method (GSSOR) with two parameters. In this note, the optimal parameters of the GSSOR method are obtained, and numerical examples are given to illustrate the corresponding results. © 2014 Elsevier B.V. All rights reserved.

the present research is concerned with the determination of ductility, over-strength and response modification factors of coupled steel shear wall frames. three structural models with various numbers of stories, bay width and coupling beam height were analyzed using static pushover and incremental nonlinear dynamic analyses. the ductility, over-strength and response modification factors for the...
