We argue that socio-technical systems can be understood as complex adaptive systems, that is, systems containing component sub-systems interacting such that they co-evolve This vie...
We argue that recent hypervisor-vs-microkernel discussions completely miss the point. Fundamentally, the two classes of systems h in common, and provide similar abstractions. We a...
We introduce a formal language for multi-agent systems based on new modal operators. The modal operators express concurrency at the syntactic level. Operators containing quantifie...
We give a coalgebraic formulation of timed processes and their operational semantics. We model time by a monoid called a "time domain", and we model processes by "t...
Three modular reduction algorithms for large integers are compared with respect to their performance in portable software: the classical algorithm, Barrett’s algorithm and Montgo...
