In this paper, we present a fast algorithm to compute the shortest path based on the last step shortest path maps. Firstly, we locate the dividing-points quickly in the two adjacent polygons, which can reduce amounts of iteratively computation. Then, we convert this problem to solving the shortest path of visiting the disjoint line segments sequence which makes the solution much simpler. Furthermore, we analyze the complexity of new algorithm and obtain that it is superior to the previous solution. Finally, we implement this algorithm and show that it is correct.","PeriodicalId":163433,"journal":{"name":"2017 6th International Conference on Computer Science and Network Technology (ICCSNT)","volume":"1996 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128206487","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 this paper, we propose Dynamic Multi-tiered Storage (DMS), which efficiently combines multi-tiered storage and deduplication based on variable-sized chunks. DMS has a high Data Elimination Ratio (DER), optimizing the storage performance of Multi-tiered storage with data elimination. We also present and implement the Dynamic Adaptive Replacement Cache (D-ARC) which bears the merits of higher efficiency, scalability, compatibility.

The system provides basic functions of data organization, data representation, query and retrieval for the coastal zone management, as well as decision-making basis for further marine environment detection, protection and area planning. The system integrates a variety of databases, to achieve the visualization of sea data management, so that information query and access are more intuitive. Marine function zoning management, analysis of coastline evolution and simulation of sea level rising are taken as three typical examples to introduce the applications of 3D coastal zone management system. The result shows that coastal zone management system makes the management of sea area more intuitive and standardized.","PeriodicalId":163433,"journal":{"name":"2017 6th International Conference on Computer Science and Network Technology (ICCSNT)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132799545","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}

Recently, Google released some new interfaces to obtain GNSS measurements which provide application developers a new option to calculate position on Android phones. In this research, the measurements are collected in Google Nexus 9 operating on Android 7.0 OS. First, some aspects, such as VSN (Visible Satellite Number), HDOP (Horizontal Dilution of Precision) and CNR (Carrier to Noise Ratio), are assessed. Then, estimated position and velocity are calculated and assessed. Finally, the precision of position generated from integrating the velocity information into estimated position with KF (Kalman Filter) is also evaluated. We believe our assessments will give application developers guidance when they use Android GNSS measurements in positioning.","PeriodicalId":163433,"journal":{"name":"2017 6th International Conference on Computer Science and Network Technology (ICCSNT)","volume":"115 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133601092","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 single sign-on (SSO) mechanism is usually exploited for user login and access control to achieve unified management and authorization. However, existing SSO can only control users' access to main coarse-grained resources of each application module. It is incapable of controlling authorized users' access to fine-grained data of specific application modules. This paper therefore introduced the cross-platform unified resource access control system (CURAC) based on URI of various resources, which includes resource-based authentication and data-based authentication mechanisms for controlling users' access to both coarse-grained resources like web pages or data tables and fine-grained data resources like column fields of a data table. Such resources are usually deployed on different platforms. Creative development and extensive deployment practices show that our cross-platform unified resource access control system (CURAC) can effectively control the access to various resources of application systems on different application platforms.","PeriodicalId":163433,"journal":{"name":"2017 6th International Conference on Computer Science and Network Technology (ICCSNT)","volume":"104 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131793463","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}

So, software reliability test is on the basis of the statistics of software practical usage.

However, the confidence parameters in this algorithm are usually chosen empirically, which has a great influence on the accuracy of engineering evaluation. In this paper, in order to improve the accuracy of the algorithm, a so-called confidence dispersion technical parameter is proposed to describe the influences of the sample data on confidence parameters in attribute recognition model. The numerical dispersion characteristics and the statistical distribution of the optimal confidence intervals are analyzed and the validity of confidence dispersion index has been proved by empirical model derivation and experimental simulation. Then a data-driven attribute recognition evaluation method is proposed based on the proposed confidence dispersion technical parameter, with the confidence parameters adaptive to sample data. According to contrastive simulation results on the technical design evaluation database of 220kV overhead line engineering projects, it has been verified that the proposed algorithm is feasible and effective, which also provides a new idea for the future design quality evaluation tasks of over-head line engineering projects.","PeriodicalId":163433,"journal":{"name":"2017 6th International Conference on Computer Science and Network Technology (ICCSNT)","volume":"151 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115316365","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}
