INTRODUCTION
Ball valves are most widely used valves for flow control in fluid flow lines for wide range of temperature changes (-200°C to 500°C).Most of the outlet valves of chemical plant storage were installed with ball valves for sudden closing and opening purposes. For petroleum and chemical plants it is very convenient to operate with ball valves.
Ball valves are used in situations where tight shut-off is required. The type of seat can vary with the valve pressure rating and m ....etc

A ball valve (like the butterfly valve, one of a family of valves called quarter turn valves) is a valve that opens by turning a handle attached to a ball inside the valve. The ball has a hole, or port, through the middle so that when the port is in line with both ends of the valve, flow will occur. When the valve is closed, the hole is perpendicular to the ends of the valve, and flow is blocked. The handle position lets you 'see' the valve's position.

Ball valves are durable and usually work to achieve perfect shutoff even after years of di ....etc

Abstract
An Algorithm is considered computationally secureif it can not be broken with standard resources, either currentor future. In this paper we have introduced a new block cipheralgorithm named X-MODDES. It is unique independentapproach which uses several computational steps along withstring of operators and randomized delimiter selections byusing some suitable mathematical logic. X-MODDES isspecially designed to produce different cipher texts by applyingsame key on same plain text. Thus a new protocol has been ....etc

ABSTRACT
The detection of moving object is important in many tasks, such as video surveillance and moving object tracking. Although there are some methods for the moving object detection, it is still a challenging area. In this paper, a new method which combines the Kirsch operator with the Optical Flow method (KOF) is proposed. On the one hand, the Kirsch operator is used to compute the contour of the objects in the video. On the other hand, the Optical Flow method is adopted to establish the motion vector field for ....etc

ABSTRACT
Selection operator is one of the important aspects in the GA process. There are several ways for selection.Some of them are Tournament selection, Ranking selection, and Proportional selection. There are manyways for proportional selection. The most popular are Roulette Wheel Selection (RWS), StochasticReminder Roulette Wheel Selection (SRRWS), and Stochastic Universal Sampling (SUS). In this paper amodified RWS method is proposed to increase the gain of resources, reliability and diversity; anddecrease the uncertainty in selec ....etc
