The closure of fractured mudstone is resulted from the deformation under the changing of stress condition, also decreased the permeability of formation, as well as shrinking the production of oil and gas wells to zero. The focus of the study is how to quantify the effect of stress change on crack closure, and the selection of the appropriate characterization parameters. We see from the obvious level, the fractures of mudstone are influenced by the change of stress, the most apparent change among parameters is the formation permeability. If we make the permeability as the parameter to characterize the degree of mudstone fracture closure, then the concentration should be the specific value we quantified to distinguish the stress leading to closure in this value, it is what my research would focusing on. In this essay, we have stimulated underground fractured mudstone conditions by artificial fracture to study the natural core of mudstone, also applied the method of displacement pressure with the experimental study of mudstone fracture closure.

SQL injection vulnerability is the one of the most common web-based application vulnerabilities that can be exploited by SQL injection attack to gain access to restricted data, bypass authentication mechanism, and execute unauthorized data manipulation language. Defensive coding is a simple and affordable way to tackle this problem, however there are some issue regarding use of defensive coding which makes the system in effective, less resistant and resilience to attack. In this paper we provide detailed background of SQLIA (SQL Injection Attack), classified defensive coding to different categories, reviewed existing technique that are related to each techniques, state strength and weakness of such technique, evaluate such technique based on number of attacks they were able to stop and evaluate each category of approach based on its deployment requirements related to inheritance. The goal of this paper is to provide programmers with common issues that need to be considered before choosing a particular technique and to raise awareness of issues related to such techniques as many of those techniques were not meant for the purpose of protection of SQLIA. In addition, we hope to provide researchers by shedding light on how to develop good SQLI (SQL Injection) protection tools as most of the SQLI protection tools were developed using combination a of two or more defensive coding techniques. Lastly we provide recommendations on to avoid such issues.

Rotational effects influence the aerodynamic performance of wind turbine rotor severely. The objective of this research attempted to study the rotational effects in the vicinity of the wind turbine blade surface. Detailed flow measurements on wind turbine blade were performed in a wind tunnel. The test wind turbine has a three-bladed rotor with a radius of 1.2m. Each blade is twisted and tapered as same as commercial wind turbine blade. The maximum power coefficient of the test wind turbine is 0.43 at the tip speed ratio of 5.2. The measured velocities around blade section were detected using a Laser Doppler Velocimetry (LDV) while the pressure distributions on blade surface were detected using 32 pressure sensors for the rotating condition. All experiments were conducted for an optimum tip speed ratio. As a result, it is clarified that the rotational effects appear obviously on the inboard of the blade. The axial and tangential velocity components indicate strong velocity gradients on the leading edge and trailing edge. The rotational effects increase the sectional lift force and delays transition point in the inboard.

In this paper we present the development of own laser diode excitation system. This system is compose by software and hardware. The purpose of this system is to excitation- control of laser diode with 532nm of wavelength. The selection of this diode laser is because weworkedon previous investigations related with amplitude and frequency phase function. With this we starting to obtain results, considering the stability of laser diode for the amplitude modulation. We presents the analysis and electronic designto monitoring the responses of optical intensity. With this paper we want to emphasize that is NOT necessary to user the owner software to control the system, you can use a free software to develop a custom systems.

A case study of the transformation of a job shop production orientation to a cellular production orientation for a family of pole-mounted conveyor belt cleaning products is described. Quick response manufacturing ideas drive the transformation primarily by minimizing customer lead time as opposed to efficiency and high utilization of equipment. The case study shows that the corporate target lead time of one day can be met by the cellular approach. In addition to the elimination of finished goods inventory, several benefits of the cellular approach were identified including minimizing the use of material handling equipment, record keeping, and worker retraining as well as increasing production agility in response to large orders.

According to the analysis of structural evolution,the fault system in Wuerxun sag was divided into four types:early extensional faults,interim strike-slip faults, early extensional—interim strike-slip faults,and early extensional—interim strike-slip—late reversed faults.In terms of the relationship of superposed faulting, early extensional—interim strike-slip—late reversed faults played a role of adjustment to hydrocarbon accumulation.At the same time,the research which includes sand distribution and its relation with faults helps us understand that the matching of "fault-sand" controled the Damoguaihe hydrocarbon accumulation.
