Generally, the test data of the low voltage switchgear are very few. In order to assess the reliability more accurately, historical data are used to maximum the capacity of the test data. The premise of using the prior information is the prior data and test data should approximately come from the same overall. This is just the problem of compatibility check. In this paper, the method of fitting data and the law of testing the distribution are used to analyze both the priori and test data. Furthermore, we present a novel method of using Wilcoxon rank sum test to check the compatibility of the prior and test data of the low voltage switchgear. Both methods lead to the conclusion that the prior and the test data of the low voltage switchgear are compatible.
In this paper, the process of acid extracting pectin from Guangyechu white bast and subsequent ammonium sulfate pulping was optimized by condition test. Under optimal conditions, the pectin yield was 3.99%, the screened pulp yield was 52.61%, KMnO4 value was 9.84 and whiteness was 51.7%ISO. And chemical compositions of Guangyechu white bast in each treatment stage were compared and analyzed.
To meet the requirements of enterprises in different developing phases, often using the latest technology under the circumstances that lead to existing many and various hardware, operating systems, middleware, programming languages, data storage, reusable redundant code in the enterprise. Service-Oriented Architecture (SOA)[1] is naturally chose as an application architecture by many enterprises because of its innate loose coupling and co-operating. In this paper you will see the Web service development tools supplied by WebSphere platform and you will also see that Web service function which is supplied by J2EE can easily build up SOA system [2] and visit the the existing business process.
In previous work, the ontology-based algorithm of bipartite graph matching semantic web service discovery was presented. But in these algorithms, the problem of finding augment path was not resolved very well. It will affect the recall rate and precision rate of web service discovery. In order to resolve these problems, this paper proposes an ontology-based bipartite graph matching semantic web service discovery algorithm, which extends the optimal bipartite graph matching algorithm. It uses the slack function to find the augment path in the equivalent sub graph. The algorithm also contributes to the improvement of the recall rate and precision rate of the service discovery.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
