This article discusses some diculties in the implementation of combinatorial algorithms associated with the choice of all elements with certain properties among the elements of a set with great cardinality.The problem has been resolved by using multidimensional arrays. Illustrati...

The operation of substitution consists of replacing a vertex of a graph by another graph. This new graph is characterized through a function (of substitution) that can be self-definable. The purpose of this work is to construct evolution operators for orbit {wk(G)}, where each el...

This paper study the two unit warm stand by system in which the demand of items increases arbitrarily for some random amount of duration. Whenever demands of items to which the machines are producing is heavy the standby unit also starts operation and when the demand becomes Norm...

The most commonly used approach for ranking fuzzy numbers is ranking indices based on the centroids of fuzzy numbers. In this paper, we introduced a new ranking method which is based on multi-index such as relative dominance, priority weight and decision-makers preference. In add...

Ray tracing is a method to convert 3D image to high quality 2D realistic image. In traditional Ray tracing technique generating an image is an expensive process due to the large number of transmitted rays and the intersection tests of these rays with the scene primitives. This pa...
