Abstract: Managing Software Project Risks (Planning Phase) with Proposed Fuzzy Regression Analysis Techniques with Fuzzy Concepts
Author abdelrafe elzamlyBurairah Hussi
Regardless how much effort we put for the success of software projects, many software projects have a very high failure rate. Tthe failure risk is not always avoidable, but it could be controllable through software development phases. The aim of this paper is to present the fuzzy regression analysis modelling techniques to mitigate the risks in a software development project in planning phase. Top ten software risk factors in the planning phase and the best thirty risk management techniques were presented to respondents. All selected risks in software projects (planning phase) were siginificance in software project manager's perspective, whereas all risk management techniques are used most of the time, and often. The study has been conducted on a group of software project managers in software development companies. Fuzzy multiple regression analysis techniques had shown that are effective in mitigating the occurrence of each software risk factor. Successful software project risk management will greatly improve the probability of project success.
- Construction of Cutting Tool Life-cycle Information Management Platform
Abstract: Construction of Cutting Tool Life-cycle Information Management Platform
Author Jing ShengYadong Fan
To improve process capability in manufacture industry, the information of cutting tool life-cycle is vital. The cutting tool life-cycle management was presented. Some key technolo¬gies were investigated, including cutting tool resource classification and code technology, etc.. Further more, the cutting tools life-cycle management system was analyzed and designed through IDEF (Integrated computer aided manufacturing definition method ) methodology, and then the key page of TLMS (tool life-cycle management system) was employed according to J2EE (java 2 platformenterprise edition (j2ee)) mode. The information management platform of the cutting tool life-cycle is an effective way to solve its shortage of resources during manufacture.

Abstract: The Reseach of the Vehicle Tracking and Illegal Trajectory Discriminant Based on Video
Author Jun GuZhenghua ZhangMin Xi
The single Meanshift tracing with RGB model always loses its target under complex condition. The Meanshift and the prediction of kalman combined in tracking moving targets could improve it. According to the initial location, Meanshift and the prediction of kalman are combined to confirm the new location being the starting point of next tracking, then the trajectories of vehicles are shown. The trajectory of vehicle can distinguish whether the vehicles break rules and regulations. Experimental results show that improved tracking algorithm under complex condition has a certain degree of improvement, and the trajectory tracking has a smooth effect, which doesn’t take too much time, and still meets the requirement of real-time. Extraction of vehicle trajectory provides the basis of illegal discrimination. The lanes and the light determine whether the vehicle has run a red light or illegal turn. The detection method can accurately discriminate illegal vehicles to make video surveillance more intelligent.
