Compatibility of web services states the fitness of services that interact with each other, and closely related to substitutability of service peers. Compatibility includes both static features and dynamic behaviors of service peers. However, most researches in dealing with compatibility are limited in static checking and in synchronous communication(More)
In designing and developing large complex products, people use models to describe and organize interrelated elements in both product systems (architecture, use cases, constraints...) and process systems (activities, deliverables, roles...). However, exchanged information is often incomplete, vague and not entirely determined at the beginning of the project(More)
MDA is an approach that using modeling languages such as UML or BON to establish requirement models for the complementary of software specification, as well as for further implementation. However, models of complex information systems always require multiple views, such as static views and dynamic views to describe different perspectives of the system, thus(More)
Workflow management systems have been widely used in business processes. It facilitates the creation of new business processes and modification of existing processes. It is sensible to resolve the potential errors and conflicts in build-time to prevent the costly failures at run-time. This paper proposed an approach with corresponding algorithms to detect(More)
This article has conducted the research to the food supply chain's security problem from the supply chain risk management perspective. The article has constructed food quality safe early warning model by the using of the BP neural network method, and has carried out the simulation testing to the model. The result has confirmed that the model is ideal and(More)
Problems often encountered in karst at Mountain city construction and other infrastructure construction. to find out the genesis model of karst is important to prevent accidents. But in many areas, there is few research about karst development pattern, such as dabashan mountain area described in this article.Through our study on the genetic model about(More)
Model driven development is an approach that using modeling languages such as UML or BON to establish requirement models for the complementary of software specification, as well as for further implementation. How ever, a model of a complex systems is always consist of multiple views, such as static views and dynamic views to describe different perspectives(More)
OBJECTIVE To establish a comprehensive analytical method based on SPE-UPLC-MS for the simultaneous determination of bisphenol A (BPA), nonylphenol (NP), and octylphenol (OP) in urine samples. METHODS Sixty urine samples collected from healthy subjects were analyzed for BPA, NP, and OP concentrations. The samples were de-conjugated by adding(More)
