To gain a bigger market share in competition and more reputation and brand value in development, distance education and training institutions must pay great attention to the satisfaction and acceptation of its students for its teaching. The rapid development of modern Information Technology (IT) brings new opportunities to promote the quality of distance education services. In this paper, we design an evaluation index system based on an \"IT application fields - service quality promotion\" two dimensions framework. The dimension of IT application fields includes academic and non-academic student support services. The dimension of service quality promotion includes tangibles, reliability, responsiveness, assurance and empathy. The quality of student support services is measured by the SERVPERF method. Finally, we also provide a case study from The Open University of China(http://ouchn.edu.cn/) to validate our assumptions.","PeriodicalId":256842,"journal":{"name":"2012 IEEE Asia-Pacific Services Computing Conference","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122025499","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}

However, despite its technical advances, cloud computing introduces many new security challenges that need to be addressed well. This is because, data owners, under such new setting, loss the control over their sensitive data. To keep the confidentiality of their sensitive data, data owners usually outsource the encrypted format of their data to the untrusted cloud servers. Several approaches have been provided to enable searching the encrypted data. However, the majority of these approaches are limited to handle either a single keyword search or a Boolean search but not a multikeyword ranked search, a more efficient model to retrieve the top documents corresponding to the provided keywords. In this paper, we propose a secure multi-keyword ranked search scheme over the encrypted cloud data. Such scheme allows an authorized user to retrieve the most relevant documents in a descending order, while preserving the privacy of his search request and the contents of documents he retrieved. To do so, data owner builds his searchable index, and associates with each term document with a relevance score, which facilitates document ranking. The proposed scheme uses two distinct cloud servers, one for storing the secure index, while the other is used to store the encrypted document collection. Such new setting prevents leaking the search result, i.e. the document identifiers, to the adversary cloud servers. We have conducted several empirical analyses on a real dataset to demonstrate the performance of our proposed scheme.","PeriodicalId":256842,"journal":{"name":"2012 IEEE Asia-Pacific Services Computing Conference","volume":"43 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132896366","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}

How to broadcast live gaming services to large-scale Internet users is still a big problem. Traditional schemes, based on Peer-to-Peer (P2P) live-streaming and based on TV shows, have poor user experiences (good graphic quality with high resolution) and need big bandwidth or TV set support. In order to avoid network congestion, a small number of solutions propose an alternative approach based on game data content instead of video content to provide game live services. At present, all of them who use client/server framework do not emphasize the design of system architecture, so the number of users is constrained and the system is hard to expand. In this paper, we introduce PKTV, a P2P game battle observing system, which is now optimized specially for War craft 3. PKTV system broadcasts game data content to reduce bandwidth overhead, maintains a P2P overlay for each gaming channel and uses a reliable UDP protocol to break the limitation of the TCP connections, decentralizes servers to enhance system's availability and scalability. Furthermore, tests and simulations show that PKTV also have robust functionality and good performance: low-latency, low bandwidth consumption and very considerable bandwidth savings for servers.","PeriodicalId":256842,"journal":{"name":"2012 IEEE Asia-Pacific Services Computing Conference","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114528458","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 scalability and compatibility of existing systems are relatively poor. The idea of Modelica provides a good opportunity for the unification of the modelling of multi-discipline VEs (MDVE). However, Modelica is an original multi-domain modelling method for scientific research, instead of for VE education. There are some obvious gaps to bring it into a MDVE platform (MDVEP), especially, if it is designed to support massive users and parallel modelling and resolving. This paper presents a new virtual experiment distributed task management system (VETMS) for MDVEP, which can improve the efficiency, stability and availability of the platform. It uses hierarchical design method to decouple the different modules and also provides a set of Application Programming Interfaces (APIs) for external calls. Besides, the system performance is also considered. A Modelica-oriented mechanism is proposed to tackle service failures. A parallelized Twisted framework is presented to overcome the problem of limitation of concurrent requests. Meanwhile, a NAT (Network Address Translator) traversal module of TCP based STUNT protocol is added to reduce the amount of data through master node. Experiment results show that the system can serve as a task management service for MDVEP with good performance.","PeriodicalId":256842,"journal":{"name":"2012 IEEE Asia-Pacific Services Computing Conference","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129190382","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}
