Being instrumental in electric energy data collection for energy data collection and supervisory systems, the reliability of an electric energy collector not only affects the reliability of the system, but also directly influences users' satisfaction. With the objective of addressing the problem of reliability assessment of an electric energy data collector, the failure mechanism of the data collector...
This paper proposed a new concept named EMC reliability to describe the capability of electromagnetic compatibility from the perspective of probability and statistics. Based on the model of EMC stress and EMC strength, an interference model between them is established to obtain the EMC reliability. The results show that this method could not only forecast the level of electromagnetic compatibility...
In this paper, we propose a novel framework WSCRec, in which historical information (i.e., execution logs) are utilized to facilitate the process of Web service composition. According to the execution logs of composite services, appropriate services which have been proved to be more reliable and robust and have higher probability to fulfill users' demands are located.
Automatic web services composition approaches aim at automatically composing services to satisfy users' request according to the information of users' input. As the number of web services is increasing, the performance of automatic service composition is faced with challenges. In this paper, we propose an approach based on backward chaining method to compose web services with high performance and...
The march-fight transform equipment pull rod is the key component for some type anti-aircraft gun. If the pull rod is broken, the safety of operation staff will be seriously threatened, and normal combat readiness training will be affected. In addition, the firing stability and movement flexibility of the anti-aircraft gun will be affected. Firstly, based on the army survey, five hypothesis of failure...
Functional verification plays a more and more important role in the design flow of intellectual property cores and embedded systems because of the increasing trends in complexity and integrity of embedded systems. To meet the demands of quality assurance and time to market, EDA companies are developing verification methods and tools that involve high-level hardware description language, reusable verification...
Urban subway is an important underground transportation facility, settlement monitoring and settlement analysis as well as settlement prediction are usually carried out in the construction process. In order to obtain a better settlement analysis and effect on predictions, the reliability of monitoring data should be first tested and analyzed. For the problem of data preprocessing in settlement monitoring,...
With the development of internet technology, the entire amount of data on the internet has shown the explosive growth. Some researchers have paid their attention to find an effective way to store and manage these data. In this paper, we introduce a load rebalancing algorithm to solve the load balancing problem among all chunk servers(compute nodes) in the distributed file system; it also ensures that...
Using the documentation, questionnaire, Delphi Method, mathematical statistics, logical analysis and so on, this paper developed the measuring list from the teaching evaluation in the practical course of physical education for three types who are leaders, teachers and students. Through the trial assessment and experimental verification, the reliability and validity for the measurement and assessment...
