XML-GL, a graphical query language for XML document, has the advantage of structuring and defining itself. By incorporating UML, an XML document can become object-oriented and can be represented by graphical means. This paper proposes an efficient query modelling of XML-GL using UML class diagram and OCL. In order to restrict properly the modeled object the Object Constraint Language(OCL) is used. By using proposed technique, we can store and manage XML documents as object-oriented data. And, we search XML documents more efficiently by a proposed query modeling technique using UML class diagram.","PeriodicalId":333607,"journal":{"name":"2009 Seventh ACIS International Conference on Software Engineering Research, Management and Applications","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115554616","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}

Due to the fact that they have to endure a big number of concurrent requests, the performance of service applications running under specific arrival rate of requests should be assessed. To measure the performance of a service application, Multi-party testing context is needed to simulate a number of concurrent requests and collect the responses. TTCN-3 is a test description language; it provides basic language elements for multi-party testing context that can be used in performance tests. This paper proposes a general approach of using TTCN-3 in multi-party performance testing service application. To this aim, a model of service application is presented, and performance testing framework for service applications is discussed. This testing framework is realized for a typical application by developing a reusable TTCN-3 abstract test suite.","PeriodicalId":333607,"journal":{"name":"2009 Seventh ACIS International Conference on Software Engineering Research, Management and Applications","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128881289","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 host-based file protection system resides the critical modules in monitored system, which is easily explored and destroyed by malwares. Moreover, in order to protect the multiple operation systems running on the same platform, it is necessary to install independent file protection system for each of them, which greatly wastes computing resources and brings serious performance overhead. In this paper, a novel VM-based real-time file protection system, named VRFPS, is proposed to solve these problems. First, virtual machine monitor introspects all file operations of guest OS. Then, semantic gap between disk block and logic files is narrowed by blktap. Finally, a virtual sandbox is implemented in privileged domain to prevent protected files in guest domain from modifying illegally. Our approach is highly isolated, transparent and without modification on virtual machine monitor and guest OS. The experimental results show that the presented system is validate and of low performance overhead.","PeriodicalId":333607,"journal":{"name":"2009 Seventh ACIS International Conference on Software Engineering Research, Management and Applications","volume":"43 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130851665","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}

Autonomous TPA means that, all tasks should be (re)planned and (re)allocated automatically according to the synthesis constraints and the dynamic environment aspects, such as the changing mission, status of each member, and topology, etc. In this article, the formal descriptions of hierarchical tasks and models of logic constraints are studied firstly. And then, some new methods are proposed to evaluate the efficiency of synthesis constraints. Moreover, the key elements, e.g. task allocation vector (TAV), are designed with the theory of genetic algorithm (GA), and a TPA problem can be mapped to the solving model of GA. Based on above, the crossover and mutation operators of GA are optimized with the domain knowledge to perfect the solving efficiency and quality while ensuring the randomicity of evolution. The simulation results show that the solving quality and velocity are improved with studied methods.","PeriodicalId":333607,"journal":{"name":"2009 Seventh ACIS International Conference on Software Engineering Research, Management and Applications","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114169760","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}
