We revisit the approach deened in 2] for the formal veriication of cryptographic protocols so as to allow for some mechanization in the veriication process. In the original approach veriication uses theorem proving. Here we show that for a wide range of practical situations and properties it is possible to perform the veriication on a nite and safe abstract model.

It is well-known that many relevant aspects of everyday reasoning based on natural language cannot be adequately expressed in classical rst-order logic. In this paper we address two of the problems, rstly that of so-called presuppositions, expressions from which it is possible to draw implicit conclusion, which classical logic normally does not warrant, and secondly the related problem of parti...

The significance of Behaviourism is examined in relation to its far conceptual roots, i.e. comparative animal studies initiated by Darwin, mechanistic physiological thinking initiated by Descartes and empiricist associationism. The Behaviourist anti-mentalist position induced neuromechanistic interpretations based on Pavlovian reflexes, stimulus-response connectionism and the very first hypothe...

We present an empirical study of mathematical proofs by diagonalization, the aim is their mechanization based on proof planning techniques. We show that these proofs can be constructed according to a strategy that (i) nds an indexing relation, (ii) constructs a diagonal element, and (iii) makes the implicit contradiction of the diagonal element explicit. Moreover we suggest how diagonal element...

It is widely recognized that the diagnostic clinical laboratory has been revolutionized during recent years by extraordinary progress and instrumentation in automation. The microbiology and immunology laboratories have not developed until quite recently a sophisticated instrumentation and automation methodology. However, such advances are dependent on both modification and expansion of conventi...
