We try to find solutions -- in the context of data structure design- that are memory efficient and low power consumption in memory usage. We analyze various existing and creative new data structure implementations of a specific embedded application. Low memory cost, data accesses and power consumption are our main criteria during our data structure explorations. 2D and 3D Pareto curves are used to present the trade-off points of different data structure implementations. Thus, the relative optimal data structures can be discovered within the real-time constraints of the application.","PeriodicalId":408357,"journal":{"name":"2012 IEEE 15th International Symposium on Object/Component/Service-Oriented Real-Time Distributed Computing Workshops","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125277796","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}

Such heterogeneity is especially true of service-oriented systems, which are often dynamic in nature and composed of multiple interacting services. However, in order to establish user trust in such systems, there is a need to determine the validity and reliability of all the data sources that go into the making of a decision. This paper analyses the concept of provenance and discusses how the establishment of personalized provenance recording and retrieval systems can be used to increase the utility of data and engender user trust in complex service-based systems. An overview of current provenance research is presented, and a real-world project to address the abstract concepts of trust and data quality in industrial and clinical settings is presented. From this, we conclude that the addition of provenance into data processing and decision making systems can have a tangible benefit to improving the trust of system users.","PeriodicalId":408357,"journal":{"name":"2012 IEEE 15th International Symposium on Object/Component/Service-Oriented Real-Time Distributed Computing Workshops","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128283544","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}

It's a challenge to design accurate personalized QoS prediction approaches for Web service recommendation due to the unpredictable Internet environment and the sparsity of available historical QoS information. In this paper, we propose a novel landmark-based QoS prediction framework and then present two clustering-based prediction algorithms for Web services, named UBC and WSBC, aiming at enhancing the QoS prediction accuracy via clustering techniques. Hierarchical clustering is adopted based on the real-word Web service QoS dataset collected with PlanetLab1, which contains response-time values of 200 distributed service users and 1,597 Web services. The comprehensive experimental comparison and analysis show that our clustering-based approaches outperform other existing methods.","PeriodicalId":408357,"journal":{"name":"2012 IEEE 15th International Symposium on Object/Component/Service-Oriented Real-Time Distributed Computing Workshops","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122233457","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}

This paper introduces a spatiotemporal consistence language for real-time systems (Shortly, STeC). The consistence requires that a process do its tasks at the required location or time. Thus, this language provides a location-triggered specification for real-time systems. The interaction between real-time agents deals with agent2agent communications. STeC looks like an extension of precess algebra CSP. But, the execution-time of actions and status of agents are stressed. Two kinds of interrupts time and interaction break are considered. Following the Dijkstra's guard style, nondeterministic choice phase guarded by communications is introduced. After setting up the syntax, its operational semantics is introduced. As an example, the railroad crossing problem is specified in terms of this language STeC.","PeriodicalId":408357,"journal":{"name":"2012 IEEE 15th International Symposium on Object/Component/Service-Oriented Real-Time Distributed Computing Workshops","volume":"48 18","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132973805","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 literatures recommend the concept of Security-as-a-Service using unified threat management (UTM) for ensuring secured services on the cloud. Through the simulation results, this paper has demonstrated that UTM may not be a feasible approach to security implementation as it may become a bottleneck for the application clouds. The fundamental benefits of cloud computing (resources on demand and high elasticity) may be diluted if UTMs do not scale up effectively as per the traffic loads on the application clouds. Moreover, it is not feasible for application clouds to absorb the performance degradation for security and compliance because UTM will not be a total solution for security and compliance. Applications also share the vulnerabilities just like the systems, which will be out of UTM cloud's control.","PeriodicalId":408357,"journal":{"name":"2012 IEEE 15th International Symposium on Object/Component/Service-Oriented Real-Time Distributed Computing Workshops","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122702065","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}

Each SaaS application is typically shared by multiple (tens or hundreds) organizations (tenants). Each tenant may have hundreds or thousands of users. Thus, the number of concurrent accesses is high. Handling a large number of user requests effectively is critical for SaaS applications. Various aspects of SaaS can have a significant impact on its scalability, including levels of scalability mechanisms, automated migration, tenant awareness, workload support, fault-tolerance and recovery, software architecture and database access. This paper identifies scalability factors and discusses their impacts on the scalability of SaaS applications. Existing approaches for addressing the scalibility of SaaS applications are also analyzed, and this paper suggests some alternatives to improve SaaS scalability based on the factors identified.","PeriodicalId":408357,"journal":{"name":"2012 IEEE 15th International Symposium on Object/Component/Service-Oriented Real-Time Distributed Computing Workshops","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130863587","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}

They are data-intensive and also computational-intensive, because often a high number of iterations is required. FPGAs are predestined for the realization of these algorithms. They are very flexible, allow a scalable parallel processing and have a moderate power consumption, even in high-performance versions. Therefore, FPGAs are highly qualified to make these applications also real-time capable. Our goal was to implement an efficient parameterizable buffering and parallel processing scheme for such operations in FPGAs, to process them as fast as possible. We developed a generic VHDL template which allows a scalable parallelization and pipelining of 2D stencil code applications in relation to application and hardware constraints.","PeriodicalId":408357,"journal":{"name":"2012 IEEE 15th International Symposium on Object/Component/Service-Oriented Real-Time Distributed Computing Workshops","volume":"112 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133458250","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, several research efforts have addressed answering skyline queries efficiently on massive uncertain datasets. However, the research lacks methods to compute these queries on uncertain data, where each dimension of the uncertain object is represented as an interval or an exact value. In this paper, we extensively study the problem of skyline query on these interval based uncertain objects, which has never been studied before. We first model the problem of querying the skylines on interval datasets. Typically, we address two efficient algorithms with I/O optimal for the conventional interval skyline queries and constrained interval skyline queries, respectively.
