On Process-Algebraic Extensions of Metric Temporal Logic,tion of alphabetised parallel composition and fixpoint operators. We use one-clock Timed Propositional Temporal Logic (TPTL(1)) as a technical tool for the decidability results and show that { TPTL(1)} with fixpoints provides a logical characterisation of the class of languages accepted by one-clock timed alternating automata.

Instead, weadvocate types refined with first-order logic formulas as a basis for behavioural type systems, and general purpose automated theorem provers

Forward with Hoare, paper introduced Hoare Logic, which is still the basis for program verification today, but is now mechanised inside sophisticated verification systems. We aim here to give an accessible introduction to methods for proving Hoare formulae based both on the forward computation of postconditions and on

The Operational Principle and Problem Frames,s on certain ideas of structure and simplicity, including a general recommendation that composition should be postponed until the parts to be composed are well understood in their preliminary isolated forms. These ideas are discussed in the light of Michael Polanyi’s notion of the. of a machine or.,

The Role of Auxiliary Variables in the Formal Development of Concurrent Programs,hey can undermine the hard won property of “compositionality”. This paper explores the issue of auxiliary variables and tries to set concerns about overuse in a wider context; it concludes with an attempt to recommend constraints on their use.
