Although the emergence of this kind of intelligent technology improves the efficiency of working, the most are accomplished based on the software, and high voltage power supply itself is lack of controlling for the process of high pressure gradient, so that it can't focus on the process of data collection well. Demand on above, we put forward design of the linear gradient of dc high voltage power supply based on X-ray machine, the system of high voltage sccurce starts from hardware and software and solves the previous problem very well at the same time. The high-voltage source uses technology of PID control (Proportional-Integral-Differential Controller), it has the function of the automatic linear gradient of and the slope of process of high pressure gradient is adjustable, and it can get the feedback all the time, the precision and ripple of output are maintained within 0.1%. The development based on the function have been put forward and is in the research, its actual value is relatively significant.","PeriodicalId":237256,"journal":{"name":"2014 IEEE/ACIS 13th International Conference on Computer and Information Science (ICIS)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123249925","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}

A drawback of traditional user-item systems is that most recommenders ignore connections consistent with the real world recommendations. Furthermore, trust-based approaches ignore the group modeling and do not respect the users' individualities in a group recommendation set. In this paper, we propose a conceptual architecture which uses the social trust consensus from users to improve the accuracy of the trust-based recommender systems. It is based on an existent model and integrates user's trust relations and item's factors into a generic latent factor model. One advantage of our model is the possibility to bias the users' similarity computation according to a trust consensus that assists in the formation of groups, such as the group of individuals who share the same content. The proposal represents the first steps towards the development of a group recommender system model. We provide an evaluation of our method with the Epinions dataset and compare our approach against other state-of-the-art techniques.","PeriodicalId":237256,"journal":{"name":"2014 IEEE/ACIS 13th International Conference on Computer and Information Science (ICIS)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123456152","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}

As an open-source implementation of MapReduce, Hadoop presents an attractive usage system for many enterprises. There are some drawbacks in a traditional Hadoop cluster deployed with a large scale of physical machines, such as burdensome cluster management and fluctuating resource utilization. Virtualized Hadoop cluster not only simplifies cluster management, but also facilitates cost-effective workload consolidation for resource utilization. In Hadoop system, the data locality is a critical factor impacting on performance of MapReduce applications. However, existing task scheduling approaches to improving data locality of virtualized Hadoop are not effective because of two levels distribution of data: virtual machines and physical servers. In this paper, we deploy virtualized Hadoop cluster in which computing node and storage node are placed in respective virtual machines to improve flexibility. We propose a novel task scheduling approach which aims to improve data locality for virtualized Hadoop cluster through migrating the virtual machine acted as computing node to the physical server running virtual machine acted as storage node that holds a data replica needed by that computing node. We evaluated our approach's efficiency on a virtualized Hadoop cluster with the aforementioned deployment for 11 computing nodes and 12 storage nodes. Our experiment results show that our approach improves performance of 86% typical MapReduce applications in our benchmark suite at varying degrees.","PeriodicalId":237256,"journal":{"name":"2014 IEEE/ACIS 13th International Conference on Computer and Information Science (ICIS)","volume":"103 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124752509","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 Web navigation patterns, termed throughout-surfing patterns (TSPs) as defined in this paper, are a superset of Web traversal patterns that effectively display the trends toward the next visited Web pages in a browsing session. TSPs are more expressive for understanding the purposes of website visitors. In this report, we first introduce the concept of throughout-surfing patterns and then present an efficient method for mining the patterns. We propose a compact graph structure, termed a path traversal graph, to record information about the navigation paths of website visitors. The graph contains the frequent surfing paths that are required for mining TSPs. In addition, we devised a graph traverse algorithm based on the proposed graph structure to discover the TSPs. This website will be hosted in a server, where we will be introducing the concept of automatic reconfiguration of storage systems. This system will be providing a master slave server where even if the master server crashes the replica of the data will be stored in the slave server dynamically and the slave server will be automatically configured as the master server. In this case the end user doesn't have to face issues with server crash, data loss, or delay of data.","PeriodicalId":237256,"journal":{"name":"2014 IEEE/ACIS 13th International Conference on Computer and Information Science (ICIS)","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130857191","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}
