Regression Analysis Techniques with Fuzzy Concepts
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.
- The Reseach of the Vehicle Tracking and Illegal Trajectory Discriminant
Based on Video
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.
- Effective Load Balancing for Wireless Sensor Networks with Multiple Mobile
Abstract: Effective Load Balancing for Wireless Sensor Networks with Multiple Mobile Sinks
Author Keiichi EndoShingo YanoDai Okan
In this paper, we propose a method that extends the lifetime of wireless sensor networks by using multiple mobile sink nodes. The proposed method determines the positions of multiple sink nodes based on remaining battery levels of sensor nodes. When a sink node is moved, the new position of the sink node is determined considering the distance to other sink nodes and the distance to the sensor node with the lowest remaining battery level. The proposed method also considers remaining battery levels in constructing routing tables. We conduct a comparative evaluation of the existing and proposed methods via simulation to demonstrate the effectiveness of the proposed method.
- Decision-making Software Architecture; the Visualization and Data Mining
Abstract: Decision-making Software Architecture; the Visualization and Data Mining Assisted Approach
Author A. Mosav
Multiple Criteria Decision Making (MCDM) is considered as a combined task of optimization and decision-making. Yet in solving real-life MCDM problems often most attention is paid to finding the complete Pareto-optimal set of the associated multiobjective optimization (MOO) problem and less to decision-making. In this paper, along with the presentation of two case studies, an interactive procedure has been suggested which involves the decision-maker (DM) in the optimization process helping to choose a single solution at the end. Our proposed method on the basis of reactive search optimization (RSO) algorithm and its novel software architecture packages of LIONsolver and Grapheur are capable of handling the big data often associated with MCDM problems. The two considered case studies are; firstly, a series of MCDM problems in construction workers’ management and secondly, the well-known MOO and decision-making problem of welded beam design.
- Simulation Study on Regulation Effects of the Mobile Market
Abstract: Simulation Study on Regulation Effects of the Mobile Market
Author Huan GuoXia JinWen Zhen
Based on the Swarm platform and adaptive agent of complex adaptive system, the simulation model of mobile telecommunications market’s regulation has been developed with the aim to simulate the effects of regulatory policies. Through the different simulation results, the implementation of regulatory policies having impact on the mobile telecommunications market can be analyzed, which provides theoretical support and basis for the future development of mobile telecommunications market’s regulatory policy, in order to avoid the unpredictable and potential risk of the regulatory policies in the effective implementation process.
- Automatic Anti-overflow Alarm Device Design of Electric Cooker
Abstract: Automatic Anti-overflow Alarm Device Design of Electric Cooker
Author Lanhua ZhangZhaojun LiuHaitao DuXiaoyan MaXiaoyan FanJinchi Zhan
In order to solve the spillover of electric cooker, a kind of automatic anti-overflow alarm device was designed to warn by different alert sounds. The small integrated assistant sensor can easily be embedded on the lid of the pot; and by hot sensor switch automatic anti-overflow alarm function was implemented. The theoretical and practical results implied that it is feasible and effective to embed the assistant device on the electric cooker pot to achieve the automatic anti-overflow alarm.
