,Halting Still Standing – Programs versus Specifications,pecification. We identify where his argument fails..Hehner claims that assuming a well-defined Halting Function for specifications leads to a contradiction by a very similar argument as assuming a computable Halting Function for programs does. In the case of programs, this argument leads to concludi

Probabilistic Choice, Reversibility, Loops, and Miracles,pretation of non-deterministic choice. Our formulation is introduced as an extension of the Prospective Values formalism we have developed to describe the results from a backtracking search. Significant features are that probabilistic choice is governed by feasibility, and non-termination is strict.

Towards a Pomset Semantics for a Shared-Variable Parallel Language,mset semantics lifts the transition trace semantics to the non-interleaving setting, where parallel events in a pomset transition trace are labeled by . actions. Most of the important laws from the interleaving setting also hold in the non-interleaving setting. Similarities and differences with othe

Generating Denotational Semantics from Algebraic Semantics for Event-Driven System-Level Language,erriding and delta-cycle. We have explored the denotational semantics [15] for SystemC using . (abbreviated as UTP) [6], where algebraic laws can be achieved based on the denotational model..In this paper, we consider the inverse work; i.e., generating the denotational semantics from algebraic seman

Obligatory

A Formal Approach to Analyzing Interference Problems in Aspect-Oriented Designs,cted by calculating the weakest preconditions. Furthermore, the calculation also provides informative guidelines on how to solve the conflicts it found. Early detecting and removing conflicts in aspect-oriented design models can improve their qualities and save plenty of costs.

Unifying Theories in Isabelle/HOL,a framework that will allow us to deal with formal methods that are semantically based, partly or totally, on UTP, for instance CSP and . . The theories presented here will allow us to make proofs about such specifications and to apply verified transformations on them, with the objective of assisting refinement and test generation.
