Book excerpt: Abstract: "We describe exploratory efforts to design and verify a compiler for a formally verified microprocessor as one aspect of the eventual goal of building totally verified systems. Together with a formal proof of correctness for the microprocessor, this yields a precise and rigorously established link between the semantics of the source language and the execution of compiled code by the fabricated microchip. we describe, in particular: (1) how the limitations of real hardware influenced this proof; and (2) how the general framework provided by higher-order logic was used to formalize the compiler correctness problem for a hierarchially structured language."

Available in PDF, EPUB and Kindle. Book excerpt: This volume contains the proceedings of the third International Workshop on Computer Aided Verification, CAV '91, held in Aalborg, Denmark, July 1-4, 1991. The objective of this series of workshops is to bring together researchers and practitioners interested in the development and use of methods, tools and theories for automatic verification of (finite) state systems. The workshop provides a unique opportunity for comparing the numerous verification methods and associated verification tools, and the extent to which they may be utilized in application design. The emphasis is not only on new research results but also on the application of existing results to real verification problems. The papers in the volume areorganized into sections on equivalence checking, model checking, applications, tools for process algebras, the state explosion problem, symbolic model checking, verification and transformation techniques, higher order logic, partial order approaches, hardware verification, timed specification and verification, and automata.

This book was released on 2012-12-06 with total page 499 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes the partially completed correctness proof of the Viper 'block model'. Viper [7,8,9,11,23] is a microprocessor designed by W. J. Cullyer, C. Pygott and J. Kershaw at the Royal Signals and Radar Establishment in Malvern, England, (henceforth 'RSRE') for use in safety-critical applications such as civil aviation and nuclear power plant control. It is currently finding uses in areas such as the de ployment of weapons from tactical aircraft. To support safety-critical applications, Viper has a particulary simple design about which it is relatively easy to reason using current techniques and models. The designers, who deserve much credit for the promotion of formal methods, intended from the start that Viper be formally verified. Their idea was to model Viper in a sequence of decreasingly abstract levels, each of which concentrated on some aspect ofthe design, such as the flow ofcontrol, the processingofinstructions, and so on. That is, each model would be a specification of the next (less abstract) model, and an implementation of the previous model (if any). The verification effort would then be simplified by being structured according to the sequence of abstraction levels. These models (or levels) of description were characterized by the design team. The first two levels, and part of the third, were written by them in a logical language amenable to reasoning and proof.

Download or read book New Essays in Free Logic written by Edgar Morscher and published by Springer Science & Business Media. This book was released on 2001-12-31 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: Free logic - i.e., logic free of existential presuppositions in general and with respect to singular terms in particular- began to come into its own as a field of research in the 1950s. As is the case with so many developments in Western philosophy, its roots can be traced back to ancient Greek philo sophy. It is only during the last fifty years, however, that it has become well established as a branch of modern logic. The name of Karel Lambert is most closely connected with this development: he gave it its name and its profile as a well defined field of research. After a development of fifty years, it is time to look back and take stock while at the same time scanning for new perspectives. This is the purpose of the papers collected in this volume. The first paper is written by Karel Lambert himself who also comments on all the papers of the other authors. In an introductory essay we give a survey of the present status of and new directions in free logic.

Download or read book Biohybrid Systems written by Ranu Jung and published by John Wiley & Sons. This book was released on 2011-11-30 with total page 231 pages. Available in PDF, EPUB and Kindle. Book excerpt: The discipline of neurodesign is a highly interdisciplinary one, while at the same time in the process of maturing towards real-life applications. The breakthrough about to be achieved is to close the loop in communication between neural systems and electronic and mechatronic systems and actually let the nervous system adapt to the feedback from the man-made systems. To master this loop, scientists need a sound understanding of neurology, from the cellular to the systems scale, of man-made systems and how to connect the two. These scientists comprise medical scientists, neurologists and physiologists, engineers, as well as biophysicists. And they need the topics in a coherently written work with chapters building upon another.

Download or read book Mathematics of Program Construction written by Jan L.A. van de Snepscheut and published by Springer Science & Business Media. This book was released on 1989-06-07 with total page 436 pages. Available in PDF, EPUB and Kindle. Book excerpt: The papers included in this volume were presented at the Conference on Mathematics of Program Construction held from June 26 to 30, 1989. The conference was organized by the Department of Computing Science, Groningen University, The Netherlands, at the occasion of the University's 375th anniversary. The creative inspiration of the modern computer has led to the development of new mathematics, the mathematics of program construction. Initially concerned with the posterior verification of computer programs, the mathematics have now matured to the point where they are actively being used for the discovery of elegant solutions to new programming problems. Initially concerned specifically with imperative programming, the application of mathematical methodologies is now established as an essential part of all programming paradigms - functional, logic and object-oriented programming, modularity and type structure etc. Initially concerned with software only, the mathematics are also finding fruit in hardware design so that the traditional boundaries between the two disciplines have become blurred. The varieties of mathematics of program construction are wide-ranging. They include calculi for the specification of sequential and concurrent programs, program transformation and analysis methodologies, and formal inference systems for the construction and analysis of programs. The mathematics of specification, implementation and analysis have become indispensable tools for practical programming.

Download or read book System Architecture written by Wolfgang J. Paul and published by Springer. This book was released on 2016-10-04 with total page 517 pages. Available in PDF, EPUB and Kindle. Book excerpt: The pillars of the bridge on the cover of this book date from the Roman Empire and they are in daily use today, an example of conventional engineering at its best. Modern commodity operating systems are examples of current system programming at its best, with bugs discovered and fixed on a weekly or monthly basis. This book addresses the question of whether it is possible to construct computer systems that are as stable as Roman designs. The authors successively introduce and explain specifications, constructions and correctness proofs of a simple MIPS processor; a simple compiler for a C dialect; an extension of the compiler handling C with inline assembly, interrupts and devices; and the virtualization layer of a small operating system kernel. A theme of the book is presenting system architecture design as a formal discipline, and in keeping with this the authors rely on mathematics for conciseness and precision of arguments to an extent common in other engineering fields. This textbook is based on the authors' teaching and practical experience, and it is appropriate for undergraduate students of electronics engineering and computer science. All chapters are supported with exercises and examples.

Download or read book Physics and Contemporary Needs written by Riazuddin and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 586 pages. Available in PDF, EPUB and Kindle. Book excerpt: These proceedings cover the lectures delivered at the Fourth International Summer College on Physics and Contemporary Needs held from June 16 - July 4, 1979 at Nathiagali, one of the scenic hill resorts in the northern part of Pakistan. The college was organised by Pakistan Atomic Energy Commission (PAEC) and co-sponsored by the International Centre for Theoretical Physics, Trieste (ICTP), Italy. It also received a financial grant from the University Grants Commi ssion for the participation of physicists from various universities of Pakistan. The college was attended by 16 lecturers and invited seminar speakers. It was attended by 186 participants from 28 coun tries and consisted of 15 concentrated days of lectures, seminars and informal discussions. These proceedings contain only regular lectures delivered at Nathiagali but the seminars held there are listed in the Appendix. This year the college put special emphasis on various energy systems, including their long term implications, and computer software. However, the lectures delivered at the college also covered a wide spectrum of physics. The series of the colleges of which the present college is the fourth one are an attempt to remove the barrier of isolation for the physicists working in developing coun tries, far removed from active centres of research. Thus these colleges could help to fill the important gap in communication between the physicists of developing and advanced countries.
