Study of Shear Strength Behaviour of Soil With Kaolinite Mixture
Abstract: An experimental testing program was undertaken for evaluating the effect of kaolinite on the strength properties of locally available sand and soil. Strength depends principally upon the content of (1) water, (2) clastic materials and (3) plastic materials. Soils are primarily of two types (1) cohesionless soils in which the strength this produced mainly by the friction of clastic particles against one another, and (2) cohesive soils in which the …

Optimization of Compressive Strength of Segmental Interlocking Stones
Abstract: The failure of most segmental interlocking stones used as pavement materials is traceable to lack of knowledge of the mix ratios that would optimize the compressive strength of the end products. In this study, the compressive strength was optimized based on Scheffe’s simplex lattice approach. The reliability of model developed was investigated using F-statistic and was found to be adequate. A computer program written in basic language was used to …

A Study on OpenMP and Irregular Programming
Abstract: Programmers need better, more reliable techniques to build parallel programs. In the task-parallel programming paradigm, the programmer defines independent pieces of work, called tasks that may run in parallel. Geometric algorithms are wonderful examples for programming, because they are deceptively easy to do with your eyes, yet much harder to implement for a machine. The goal of parallel algorithm design is to develop parallel computational methods that run very fast …
