Business process modelling and workflow process execution are often conducted in diverse environments and described using diverse process definition languages. Such systems often underpin distributed collaboration systems, but there is a current need to allow developers to use existing and familiar design methodologies and tools to design these systems.(More)
Museum and recent collections of raccoon hair were used to assess whether temporal or spatial trends existed in MMHg distributions in south Florida. The hypothesis that MMHg in raccoon hair had remained the same since 1947 could not be rejected. Some sampling regions showed increases while others did not. However, large differences existed between sites,(More)
Since the late 1980s, elevated levels of mercury have been reported in the tissues of the Florida panther (Puma concolor coryi) from the Florida Everglades. The extent, degree, and length of time of mercury contamination in the Florida panther are unknown. The objective of this study was to determine the historical and other patterns of monomethyl and(More)
Formal Concept Analysis (FCA) is a concept clustering approach that has been widely applied in ontology learning. In our work, we present an innovative approach to generating information context from a tentative domain specified scientific corpus and mapping a concept lattice to a formal ontology. The application of the proposed approach to Semantic Web(More)
Existing software systems designed to support learning do not adequately provide for vicarious learning in a cross-institutional collaborative environment. We have developed an architecture based on role-based access control, which provides the necessary security, robustness, flexibility, and explicit formulation of policy. Such an architecture is general(More)
Presents initial findings in evaluating specific requirements for software process improvement in geographically distributed processes and suggests possible solution approaches. A case study was designed with the purpose of identifying key issues of successful software development in a geographically distributed environment. The results of the case study(More)
