  abstract=      "Circus is a new notation that may be used to specify both
     data and behaviour aspects of a system, and has an
     associated refinement calculus. Although a few case studies
     are already available in the literature, the industrial fire
     control system presented in this paper is, as far as we
     know, the largest case study on the Circus refinement
     strategy. We describe the refinement and present some new
     laws that were needed. Our case study makes extensive use of
     mutual recursion; a simplified notation for specifying such
     systems and proving their refinements is proposed here."
