Aimed at the problem of the diversity of quality evaluation as well as the description of the vagueness of the language, in view of the fuzziness and diversity of service evaluation attributes, this paper proposes a group-decision service composition method based on fuzzy numbers, which can realize service evaluation by triangular fuzzy numbers. Unified processing and quantitative description of service composition are carried out, and multi-attribute group decision-making method based on cut-set matrix evaluation is adopted to optimize service composition. Finally, it proves the reliability of the algorithm through the web services combination of case analysis and simulation experiment, and improves the service quality of the combination.","PeriodicalId":162067,"journal":{"name":"Proceedings of the 3rd International Conference on Computer Science and Application Engineering","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122471611","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The last decade has witnessed an explosion in the availability of terrain data with high resolutions. Hence, it is essential to develop efficient viewshed analysis system to process these data. This paper demonstrates the design and engineering of an interactive online viewshed analysis system named HiViewshed on massive grid terrains. HiViewshed takes advantage of hybrid parallel computing architectures with message-based and shared-memory parallelism, and it has overcome problems and deficiencies of the existing systems. The main features of the system include (a) MPI/OpenMP based parallel computing of total viewshed analysis for multiple observation points in a large region, (b) parallel DEM data access with multi-resolution strategy ensuring online analysis quality with limited bandwidth and computing resources, and (c) favorable parallel acceleration and scalability in cluster architecture. Experimental results have shown that, it can respond in an acceptable time with several hundreds of observation points simultaneously.","PeriodicalId":162067,"journal":{"name":"Proceedings of the 3rd International Conference on Computer Science and Application Engineering","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126989924","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditional research methods, which use spatial or semantic similarity to calculate the correlation between regions, have certain one-sidedness and limitations. The network topology can clearly represent the relationship between entities. However, semantic relationships are difficult to define, so there are few cases where network-related algorithms are used to solve the relevance of geographic entities. With the development of the Internet, web pages provide people with a huge amount of information, and geographical names as a key element are often ignored by researchers, and the rich semantic information contained in it needs further research. This study attempts to explore the geographic entity relevance of integrated semantics and spatial factors based on textual data from a network perspective. Based on the community mining algorithm, the experiment studies the aggregation characteristics of geographic entities and can find areas that are close to each other and tightly related, which is more satisfied with people's common sense.","PeriodicalId":162067,"journal":{"name":"Proceedings of the 3rd International Conference on Computer Science and Application Engineering","volume":"1156 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134254247","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In these digital signature schemes, the extended Euler-phi function is φ(n) = (p4 - 1) (q4 - 1) compared to the classical Euler-phi function φ(n)=(p-1)(q-1) where n is a product of two large primes p and q. The encryption exponent is chosen to be coprime to the extended Euler-phi function. Thus, the encryption exponents have more options, which provides more security than that of the classical case. The securities of digital signature schemes depend on the difficulty of factoring large integers into a product of primes, and logarithmic computations in the ring Z[e2πi/5] Some numerical examples are given.","PeriodicalId":162067,"journal":{"name":"Proceedings of the 3rd International Conference on Computer Science and Application Engineering","volume":"82 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115030159","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Taking the modeling of crowd protection/evacuation behavior in mass incidents as the application background, this paper proposed a novel containment control method with multi-dynamic leaders and global support trajectory and formation constraints. Our method can make the moving trajectories of multiple dynamic leader agents meet the constraint of support trajectories and desired formation, and drive the moving trajectories of the follower agents to converge to the dynamic convex hull composed of multiple leaders. On this basis, the models of crowd protection/evacuation behavior are constructed by introducing the community division algorithm.","PeriodicalId":162067,"journal":{"name":"Proceedings of the 3rd International Conference on Computer Science and Application Engineering","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124483677","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
