Dynamics of dissipative gravitational collapse.
In this study we generate the matching conditions for a spherically symmetric radiating star in the presence of shear. Two new exact solutions to the Einstein held equations are presented which model a relativistic radiating ...
A simulation modeling approach to aid research into the control of a stalk-borer in the South African Sugar Industry.
The control of the African stalk borer Eldana saccharina Walker (Lepidoptera: Pyralidae) in sugarcane fields of KwaZulu-Natal, South Africa has proved problematical. Researchers at the South African Sugarcane Research ...
Coagulation-fragmentation dynamics in size and position structured population models.
One of the most interesting features of fragmentation models is a possibility to breach
Character tables of the general linear group and some of its subgroups
The aim of this dissertation is to describe the conjugacy classes and some of the ordinary irreducible characters of the nite general linear group GL(n, q); together with character tables of some of its subgroups. We study ...
A comparative study of collocation methods for the numerical solution of differential equations.
The collocation method for solving ordinary differential equations is examined. A detailed comparison with other weighted residual methods is made. The orthogonal collocation method is compared to the collocation method ...
On the logics of algebra.
We present and consider a number of logics that arise naturally from universal algebraic considerations, but which are ‘inherently unalgebraizable’ in the sense of [BP89a], essentially because they have no theo- rems. Of ...
Embedding theorems and finiteness properties for residuated structures and substructural logics
Paper 1. This paper establishes several algebraic embedding theorems, each of which asserts that a certain kind of residuated structure can be embedded into a richer one. In almost all cases, the original structure has a ...
