webπ is a recent process calculus introduced to formally specify Web Services composition. It extends the π-calculus with timed workunits, namely an asynchronous and temporized m...
A timed extension of π-calculus with a transaction construct – the calculus webπ – is studied. The underlying model of webπ relies on networks of processes; time proceeds as...
Hierarchical graph definitions allow a modular description of graphs using modules for the specification of repeated substructures. Beside this modularity, hierarchical graph de...
Abstract. Component-oriented programming yields a tension between higherorder features (deployment, reconfiguration, passivation), encapsulation, and component sharing. We propose...

There is significant interest in the use of Z in conjunction with object-orientation. Here we present a new approach to structuring Z specifications in an object-oriented (OO) st...
