Engineering component-based software systems in a distributed fashion is challenging. Particular issues to address include software process and work co-ordination, sharing and collaborative editing of component specifications, designs and implementations, and appropriate sharing of reusable components. This paper describes our approach to tool support for distributed component engineering. Seve...

Web services can be seen as a newly emerging research area for Service-oriented Computing and their implementation in Serviceoriented Architectures. Web services are self-contained, self-describing modular applications or components providing services. Web services may be dynamically aggregated, composed, and enacted as Web services Workflows.

The objective of this paper is to discuss how to use Information Technology to enable the staff at a mission-critical order packaging department to cope with a drastically increasing scale of operation. To reduce the risk of interrupting the production, a cultivation approach is adopted. We use co-ordination theory to analyse the current work setting and present a design proposal. The basic bui...

Macroinvertebrate communities and environmental variables were assessed seasonally for 1 year in a temporary river in South Portugal receiving an effluent with high conductivity, pH, sulphates, nitrates and low oxygen content. The usefulness of the ordination method canonical correspondence analysis (CCA) and the classification method cluster analysis (UPGMA) were examined to evaluate the pertu...
