Cost and scalability benefits of Cloud storage services are apparent. However, selecting a single storage service provider limits availability and scalability to the selected provider and may further cause a vendor lock-in effect. In this paper, we present MetaStorage, a federated Cloud storage system that can integrate diverse Cloud storage providers. MetaStorage is a highly available and scalable distributed hash table that replicates data on top of diverse storage services. MetaStorage reuses mechanisms from Amazon's Dynamo for cross-provider replication and hence introduces a novel approach to manage consistency-latency tradeoffs by extending the traditional quorum (N,R,W) configurations to an (N_P,R,W) scheme that includes different providers as an additional dimension. With MetaStorage, new means to control consistency-latency tradeoffs are introduced.

Consumption of business processes provided in form of Web sites have become a part of our daily life for attending our personal and business needs. In order to obtain the best solution for a particular task, users often combine several Web sites. However, currently the composition of Web sites, coordination of the execution of such Web sites compositions is done completely manually. In this paper, we present an approach that allows users to automatically compose generic solutions by combining appropriate Web sites and invoke the generic solutions with appropriate parameters whenever required, thus relieving them from a lot of manual coordination effort. We show how Web sites and their compositions can be formalized as processes, how the formal descriptions of Web sites can be automatically composed to obtain generic solutions and how such generic solution can be executed inside a common Web browser with automatic flow of data among different parties despite heterogeneous data.

Initiatives of making government data open are continuously gaining interest recently. While this presents immense benefits for increasing transparency, the problem is that the data are frequently offered in heterogeneous formats, missing clear semantics that clarify what the data describe. The data are displayed in ways, which are not always clearly understandable to a broad range of user communities that need to make informed decisions. We address these problems and propose an overall approach, in which raw statistical data independently gathered from the different government institutions are formally and semantically represented, based on an ontology that we present in this paper. We further introduce the approach deployed in publishing these data in alignment with Linked Data principles, as well as present the methods implemented to query single or combined dataset and visualize the results in understandable ways. The introduced approach enables data integration, leading to vast opportunities for information exchange, analysis on combined datasets, simplicity to create mashups, and exploration of innovative ways to use these data creatively.

This paper presents the application of Wavelet based State Dependent Parameter (WSDP) models to the identification of a Continuous Stirred-Tank Reactor (CSTR). Here, in order to characterize the process dynamics which is highly nonlinear and multi-variable dependent, 2-D WSDP model is used. The simulation results demonstrate the effectiveness and advantages of the identified model.
