Received (to be inserted Revised by Publisher) Business environments have become exceedingly dynamic and competitive in recent times. This dynamism is manifested in the form of changing process requirements and time constraints. Workkow technology is currently one of the most promising elds of research in business process automation. However, workkow(More)

Current approaches to Business Process Management (BPM) and Operational Business Intelligence (BI) integration have been very limited and simply reduced to the problem of technical integration between BPM and BI systems. This research aims to demonstrate that further opportunities for business value creation could be discovered through systematic analysis(More)
Mycobacterium tuberculosis genome contains four related sets of an operon called mce (mce1-4). The disruption of one of these operons, mce1, causes M. tuberculosis to become hypervirulent, whereas the mce3 and mce4 operon mutants are attenuated in mice. This study examined the phenotype of the mce2 operon mutant. The deletion of mce2 operon in M.(More)
Despite obvious domination of asynchronous collaborative technologies, especially for virtual classrooms and distance education , the work presented in this paper is based on the assumption that some students will still prefer the experience of on-campus, face-to-face collaborative learning. For those students a new synchronous collaborative environment is(More)
The Mycobacterium tuberculosis genome contains four copies of an operon called mce (mce1-4). Previously we reported that M. tuberculosis disrupted in the mce1 operon is more virulent than wild-type M. tuberculosis in mice. We generated single deletion mutants in mce3 (Deltamce3) and mce4 (Deltamce4) operons and a double deletion mutant (Deltamce3/4).(More)
Primitive support for time management has been recognised as one of the most significant limitations of today's workflows. In this paper, we propose a new temporal model for production workflows. After introducing basic features of the temporal model, we describe two time visualisation concepts: the duration space and the instantiation space that are used(More)
