Despite many years of ubiquitous computing (ubicomp) middleware research, deployment of such systems has not been widespread. We suggest this is in part because we lack a shared mo...
We describe an agent-based situation-aware survivable architecture for the discovery and composition of web services. Our architecture provides for proofs that guaranteethe consis...
The world-wide-web does not support referential integrity, i.e. dangling references do exist. This can be very annoying; in particular, if a user pays for some service in the form...
The process of design search and optimisation is characterised by its computationally intensive operations, which produce a problem well suited to Grid computing. Here we present a...
