A novel data partitioning method adapted to a distributed parallel streams processing system for power industry is proposed. This method uses change-aware sampling algorithm that can guarantee low error to describe the distribution characteristics of the data-values first. And then it uses an improved heuristic constructing equal depth histograms algorithm to generate approximate partition vector efficiently. Experiments results on actual data prove that the proposed method is efficient, practical and suitable for time-varying data streams processing

Migrating workflow is an effective resolution to solve the problems of incomplete specification of business process and frequent changes of environment in workflow management community. Communication mechanism between different instances is one of the most important components to enable effective negotiation and cooperation in an autonomous alliance. However, existing communication schemes are not suitable for the dynamic and prompt self-organization of migrating instance alliance. In this paper, a reliable asynchronous communication model based on existing forwarding proxy and mailbox methods is provided to deal with such problems. The model captures the primary features on configuration and task execution of migrating workflow and balances between reliability and performance of the system. A series of algorithms are also presented to support reliable and asynchronous communication, efficient location tracking and timely proxy update. Moreover, original simulations show that the model can ensure reliable inter-instances communication, and keep overheads at reasonably low

A key challenge in Web services security is the design of effective access control schemes that can adequately meet the unique security challenges posed by the Web services paradigm. Despite the recent advances in Web based access control approaches applicable to Web services, there remain issues that impede the development of effective access control models for Web services environment. Amongst them are the lacks of context-aware models for access control, and do not deal with composite Web service. In this paper, we present a context-aware role-based access control model (CGRBAC) to addresses these issues. The proposed approach introduces global roles which are used in the mapping to local roles of other services providers. We outline the configuration mechanism needed to apply our model to the Web services environment

The computing grid is becoming the platform of choice for large-scale distributed data-intensive applications. Performance measurement, analysis and prediction have become increasingly important in a grid environment, mainly due to resource's geographic distribution, heterogeneity, dynamic, distributed ownership with different policies and priorities, varying loads, reliability, and availability conditions. Resource management and scheduling based on performance prediction can allocate more availably resources and schedule tasks to meet user's performance requirement. Resource performance includes many factors. A performance prediction model is put forwards to deal with task running times. The model is based on host load and can online predict the running time of tasks on candidate hosts. The system is evaluated using over 3000 randomized test cases. The experimental result shows that the model is practical and effective and its precision is preferable

EPCglobal network is aimed to capture the real-time dynamic information about the flow of goods in the global supply chain. The global data synchronization network (GDSN) can automatically synchronize the static product information among trading partners. To maximize the efficiency of the global supply chain and further increase the market share and revenues of companies, these two technologies must be integrated to support full and highly-efficient collaboration among trading partners. This paper proposes a model to integrate these two networks, and discusses the key issues and technologies for implementation of the integration model. Intelligent e-catalog matching is at the heart of this integration. Because of lack of unified e-catalog standards, we propose to use ontology to solve the e-catalog matching problems and introduce a matching algorithm to maximize the accuracy of product searching in product sourcing operations

In recent years, enterprises of different sizes are faced with the challenges of efficiently integrating their business functions and associated systems. With the advent of service-oriented architecture (SOA), these enterprises are exploring the development of business integration solutions based on SOA. A service is defined as a particular business or IT function that is accessible by independent users and systems through a standardized interface. With their very nature, the results of using a business or IT service can be non-deterministic, i.e., one can't predict ahead of time the outcomes of invoking a business or IT service. For instance, a business service might provide a result short of the original expectation, which would require the use of another business service to compensate for the shortfalls. In this paper, we are going to propose a framework for service-oriented business integration under uncertainties. In this framework, we describe how to achieve better business and IT integration results by composing a set of appropriate business and IT services through a service composition model with uncertainties. The framework furthermore provides a structure of how the service composition model with uncertainties can be established and maintained

Web services are increasingly used to enable interoperability and flexible integration of e-business systems. In this paper we focus on measurement-based performance analysis of an e-commerce application which uses Web services components to execute business operations. In our experiments we use a session-oriented workload generated by a tool developed accordingly to the TPC-W specification. The empirical results are obtained for two different user profiles, Browsing and Ordering, under different workload intensities. Unlike the previous work which was focused on the overall server response time and throughput, we present Web interaction, software architecture, and hardware resource level analysis of the system performance. In particular, we propose a method for extracting component level response times from the application server logs and study the impact of Web services and other components on the server performance. The results show that the response times of Web services components increase significantly under higher workload intensities when compared to other components. From the hardware resource measurements it is obvious that the higher response times of Web services components are due to parsing XML messages and contention for database resources. The results of our study identify software components and hardware resources which are potential bottlenecks in the system and thus provide valuable information for capacity planning of e-commerce applications

Cost and efficiency are important incentives for academic oriented collaboratories, where researchers and analysts can work and experiment with advanced remote equipment. Such collaboratories are not suitable for industrial use, because they include experimental instruments instead of of-the-shelf instruments, and because industry requires other security and reliability implementation. This paper presents an industrial collaboratory that aims to support the daily work of material analysts. It supports natural collaboration between analysts and with customers and supports remote control of sophisticated of-the-shelf instruments. The paper includes a sketch of the technical architecture and elaborates on business models for commercial exploitation of the collaboratory

Designing a dialogue strategy for speech-enabled mobile commerce is a significant challenge due to the context. This paper introduces a hybrid dialogue strategy to overcome the inflexibility of application-directed interactions while avoiding the significant recognition difficulty of a full mixed-initiative style. The system uses N-gram grammars to govern the recognition at the request segment of a dialogue, and employs an application-directed strategy at the clarification discourse segment. The paper also details generating a corpus for the N-gram grammar through a case-based reasoning approach, and constructing application-directed dialogues with decision trees. Our preliminary testing indicates the strategy is a feasible and effective solution for voice-enabling mobile commerce applications
