This work intends to study and analysis all operations used in water jet technology and their related applications. This work aimed to study the abrasive machining by forcing the abrasive particles, or grains, into the surface of the workpiece. Testing abrasive jet which uses a mixture of water and abrasive to more effectively cut through materials. Studying material response to impact either as ductile or brittle erosion. Ductile erosion is relevant to metals and similar materials that are capable of significant plastic deformation. Brittle erosion applies to ceramics, glasses, and hard metals that crack and fragment under impact. The paper aims to Analyze and study the most important variables in impact erosion, i.e., impact velocity and impact angle affecting material removal the main objectives of the study is to study the abrasive machining by forcing the abrasive particles, or grains, into the surface of the workpiece. Testing abrasive jet which uses a mixture of water and abrasive to more effectively cut through materials. Studying material response to impact either as ductile or brittle erosion. Analyze and study the impact velocity which considered as the most important variable in impact erosion.

Through the parametric design and FEA function of CATIA, we build 3D model and finite element modal of Vibro Ripper gear. Meanwhile, we make modal analysis of gear and get natural frequency and modal shape of it.The analysis shows when the gear rolls at a high speed, gear will create a centrifugal stiffening effect on account of the centrifugal elastic deformation. Besides, the natural frequency increases with gear's speed and some modal shape changed. Moreover, the radius and thickness of block have a great impact on gear's modal analysis, and radius impactsfrequency more intricate than thickness.

Crime has carved its new way through unorganized urban life and changing city fabric. The urban fabric of any city can be reason for the crime to happen and at the same time it can contribute for its prevention. It has been always a question in the research works of many designers, planners, criminologists to get advanced in terms of design which will curb crime in different parts of the cities. This paper discusses about the establish important relationship between nature of crime and urban fabric by the researchers and presents a model in the form of five parameter of urban form which indicates that by emphasizing on these parameters can solve the problem of crime in the city. These parameters changes with nature of the city as it further adapts the variables engraved in each fabric of the city. The proposed parameters for Raipur city are: accessibility, legibility, occupancy rate, territoriality and natural surveillance.

 

Key words: Urban form, crime, fear, accessibility, legibility, surveillance, territoriality.

Through the analysis of the contradiction between the research results and the exploration of the sedimentary system of the former, it is believed that there is a lack of understanding of the source system in the north-east of Ansai area. In this paper, from the single factor, such as the color of mudstone, the distribution of carbonaceous mudstone, characteristics of heavy minerals, detrital component and the maximum particle diameter, the source system of Chang 63 sand formation in Ansai Oilfield are analyzed. Studies have shown that Chang 63 sand formation in Ansai Oilfield exists two different provenance system, which north-west region of sediment sources come from the northern provenance system, and sediment sources in the south-east region from north-east provenance system.

This paper aims to present a suggestion to construct a hybrid power plant that can generate continuously power all the time. The plant depends mainly in using traditional generators using diesel or gas as the source of power, on the other hand renewable sources of energy are adopted. In the usual case when there is no wind or solar sources, the plant can generate the power using gas or diesel. It is found that the power generated from such firms depends mainly on both number of photovoltaic panels and wind speed. Also on the solar radiation of that area. As the speed of the wind increases the power generated increases. Also the power increases as the number of photovoltaic increases the power also increases.

Keywords: power plants, renewable energy, solar, wind energy.

This paper presents a study of the bad components of the Jordanian cement and its effects on the quality of the constructions compared with standards or international cements. As the bad components increases the quality of the cement decreases. This study focuses on reveal such components and studying their effects on the cement quality and their future effects on the concrete construction. It is found that as the percent of bad components of cement (like gypsum) increases the quality of cement decrease and so the quality of constructions decreases.

The present study considers the idealized failure configuration of two cylindrical concrete specimens, geometrically and physically analogous under the action of an axial compressive load. Geometric analysis of two cylindrical specimens with different aspect ratios after failure allows introducing a concept of fracture angle, which is assumed to be constant for the same concrete grade, and its value is a function of concrete strength. Knowing the angle of the fracture plane, two equations were proposed to estimate the mechanical properties of concrete. The practical significance of the prediction value of the fracture angle and the equations presented for tensile and shear strength of concrete is verified through theoretical analysis and the results of test data.

Reservoir heterogeneity is an important basis of exploration and development strategy, so a comprehensive reservoir evaluation can lay a reliable geological foundation of the formulation and adjustment of the development plan considering the influence of different parameters on the reservoir properties, cluster analysis is adopted to reasonably optimize the geologic and development parameters that can reflect the reservoir property. By using the comprehensive quantitative classification method of principal component analysis, we can determine the weight of each influencing factor, and then calculate the comprehensive evaluation index. At last, we can determine the classification boundary according to the cumulative- probability distribution curve, and finally complete the comprehensive classification evaluation of reservoirs.

Outsourcing is a management practice which largely dominates today's global economy. It is often defined as the "transfer of an organization business function to an external vendor". Currently, an increasing number of organizations are outsourcing part or their entire IT portfolio. The main reasons firms choose to outsource is the need to focus on their core business and to reduce costs. This paper analyzes the state of information systems outsourcing in some African countries, focusing on challenges they are facing along with strength and advantages that will help them overcome those challenges.
