Abstract. Refinement plays a crucial role in "top-down" styles of verification, such as the refinement calculus, but for probabilistic systems proof of refinement is a pa...
One of the major issues for user assistance systems consists of “providing help at an appropriate level”. In this paper we analyze the problem of modeling task experience — ...
We present a restriction of the solos calculus which is stable under reduction and expressive enough to contain an encoding of the pi-calculus. As a consequence, it is shown that ...
In this paper we explore how application-users can, in an interactive way, test properties about the state of GUI applications that can be classified as local state transition sys...
Abstract— This paper derives a novel property of the secondorder modes of discrete-time systems under variable transformation. This is the generalization of the theory presented ...
