The IT industry traditionally offers system services to user companies. The services which integrate software and hardware products are geared toward product-based business models. However, with the emergence of cloud computing, users’ in-house systems and applications are virtualized on the net, and are replaced with ones provided through(More)
Identity federation is a powerful scheme that links accounts of users maintained distinctly by different business partners. The concept of network identity is a driver for accelerating automation of Web Services on the Internet for users on their behalf while protecting privacy of their personally identifiable information. Although users of Web Services(More)
The identification of a series of compounds that specifically inhibit efflux by the MexAB-OprM pump system in Pseudomonas aeruginosa is described. Synthesis and in vitro structure-activity relationships (SARs) are outlined. Early leads lacked activity in animal models, and efforts to improve solubility and reduce serum protein binding by the introduction of(More)
This paper proposes a framework, which integrates the development and operation environments for cloud applications. Adopting perspectives on lifecycle management, the framework is equipped with tools and platforms, which seamlessly integrate lifetime phases: requirement analysis, architecture design, application implementation, operation and improvement.(More)
In today's fast and ever changing business environments, it is very important to quickly adapt business processes to new business requirements, and to optimize their performance. From this viewpoint, business process performance prediction plays a key role in directing the business. Previous studies have shown that a network queuing model is able to predict(More)
This paper presents an approach to automate modification of development assets - both test programs and system codes in continuous service development. This approach is attained by metadata, which describes structural behavior and used for transmitting updates among design model, test components, and system under test. This mechanism is illustrated with a(More)
While a streaming-XPath engine provides a more efficient XPath evaluation performance than a DOM based engine, it still requires time to parse a whole XML document at least once. Taking into consideration that XPath is used to extract data from Web service messages, the target element may be in the first part of documents, such as the SOAP headers.(More)
In this paper, we present an approach for maintaining consistency among design models, system under test, and test components. Our approach provides an automatic updating technique to deal with changes that happen frequently in agile software development. Consistency reflection by automatic updating allows us to cut off manual tasks required in maintaining(More)
