This study describes the improvement of the reliability and effectiveness of the straight flow used in piston compressors, valves, and by modeling the flow of gas and the movement of plate valve. This model distributes the gas pressure and distortions plate valve as a flexible plate to be determined. This modeling test gas flow through the valve in the static measurements in addition to dynamic measurements of the end plate valve movement in the compressor has checksum where the comparison between numerical results and experimental results measured.

Ship collision accidents are considered of the most serious incidents, due to the subsequent disastrous results both in terms of economic losses in ships and cargo, and the loss of human life as well as the great environmental pollution caused by i t. Therefore, continuous efforts are being made by research centers in order to understand the structural response of the hull as a result of these incidents and accurately analyzed. This research is interested in assessing the residual structural strength of a ship exposed to collision through the internal energy and the various structural stresses generated within it. The case is modeled for an oil tanker exposed to collision by the bulbous bow of another vessel moves at different speeds and different angles. The structural strength of the middle section of the struck ship was analyzed based on the numerical methods using Ansys Dynamic Explicit program. Which allowed the development of a clear vision for the structural changes and internal stresses energy with time during the collision process.
The research aims to find a way to calculate the hydrodynamic and thermal characteristics of devices absorption foam used in the wet roads to clean the combustion products of SO2 to increase the effectiveness of these methods and economic. For it h as been studied heat exchange and hydrodynamic device absorption with bilateral phase moving layer (foam) with different models of contact devices, and on the basis of experimental data and mathematical analysis have been obtained equations that allow assessment of the impact of contextual factors in the core layer foam variables. It was also stressed that the heat exchange in the field of foam layer is characterized by high efficiency heat exchange between the gas and the liquid in the foam layer and between the foam layer and the surface submerged, and give the temperature coefficient depends on the initial conditions of gaseous and liquid phase and the temperatures of the dew point of the gas and liquid teams at the entrance device absorption. As for the effectiveness of cleaning the combustion gases from the cleaning degree of SO2 in the upper border of the foam system up to (95,95%) on stage touches one. The study also allowed increase reliability for wet cleaning system by selecting the optimum poisoning and on the basis of data obtained.
This work aims to find approximate relationships to calculate the static durability of ball valve disc valves, based on material resistance and flexibility theory. Three groups were obtained, and these groups represent three mathematical charts, each of which corresponds to specific relationships obtained to calculate the stresses generated in the dish.
Software engineering is an important concept for the development of information systems, which is more than coding or writing of programs, that it includes quality, scheduling, economics and knowledge of the application of principles. Software is s ubject to errors in manufacturing and operation and needs to be evaluated like any other product. In this research paper, we present a development of the traditional programmatic model of software engineering using the CRISP-DM methodology, which is primarily used in data extraction engineering systems, that aims to improve software quality. We study the effect of introducing this methodology in terms of reducing the number of errors discovered in software and its impact on error detection at an early stage of the software life cycle. The results showed that the use of this methodology helped to reduce the errors discovered in the software after the development process. It also helped to detect a greater percentage of errors in the early stages of the software life cycle, which helps to increase the quality of the software, compared to a relatively low number of lines. Code because of applying the proposed methodology.
There are many of Formal Methods for testing security protocols detecting being safe or not. Including Avispa, Casper, ProVerif, Scyther. Previously a comparisons using two of mentioned methods (ProVerif, Scyther). In this, research a comparison b etween the four mentioned methods in terms of the same used parameters in the previous comparison: working style, the modeling language, user interface, input, and output. As a result, the user provided with options to choose the appropriate method depending on the desired parameter. Six different of security protocols have been tested and finally the results have been compared; these protocols are Kao Chow Authentication Protocol, 3-D Secure Protocol, Needham-Schroeder Public Key Protocol, Diffie–Hellman key exchange, Andrew Secure RPC Protocol, and Challenge Handshake Authentication Protocol
