Bisimulations for a Calculus of Broadcasting Systems
We develop a theory of bisimulation equivalence for the broadcast calculus CBS. Both the strong and weak versions of bisimulation congruence we study are justi ed in terms of a cha...

Model order reduction of nonuniform transmission lines using integrated congruence transform
This paper presents a new algorithm based on Integrated Congruence transform for the analysis of both uniform and nonuniform transmission lines. The key advantage of the proposed ...

Is Observational Congruence Axiomatisable in Equational Horn Logic?
It is well known that bisimulation on µ-expressions cannot be finitely axiomatised in equational logic. Complete axiomatisations such as those of Milner and Bloom/´Esik necessar...

Using Tractable and Realistic Churn Models to Analyze Quiescence Behavior of Distributed Protocols
Large-scale distributed systems are subject to churn, i.e., continuous arrival, departure and failure of processes. Analysis of protocols under churn requires one to use churn mod...
