Finding Your Way Through Formal Verification


Book Description

There are already many books on formal verification, from academic to application-centric, and from tutorials for beginners to guides for advanced users. Many are excellent for their intended purpose; we recommend a few at the end of this book. But most start from the assumption that you have already committed to becoming a hands-on expert (or in some cases that you already are an expert). We feel that detailed tutorials are not the easiest place to extract the introductory view many of us are looking for - background, a general idea of how methods work, applications and how formal verification is managed in the overall verification objective. Since we're writing for a fairly wide audience, we cover some topics that some of you may consider elementary (why verification is hard), some we hope will be of general interest (elementary understanding of the technology) and others that may not immediately interest some readers (setting up a formal verification team). What we intentionally do not cover at all is how to become a hands-on expert.




Systems of Formal Logic


Book Description

The present work constitutes an effort to approach the subject of symbol ic logic at the elementary to intermediate level in a novel way. The book is a study of a number of systems, their methods, their rela tions, their differences. In pursuit of this goal, a chapter explaining basic concepts of modern logic together with the truth-table techniques of definition and proof is first set out. In Chapter 2 a kind of ur-Iogic is built up and deductions are made on the basis of its axioms and rules. This axiom system, resembling a propositional system of Hilbert and Ber nays, is called P +, since it is a positive logic, i. e. , a logic devoid of nega tion. This system serves as a basis upon which a variety of further sys tems are constructed, including, among others, a full classical proposi tional calculus, an intuitionistic system, a minimum propositional calcu lus, a system equivalent to that of F. B. Fitch (Chapters 3 and 6). These are developed as axiomatic systems. By means of adding independent axioms to the basic system P +, the notions of independence both for primitive functors and for axiom sets are discussed, the axiom sets for a number of such systems, e. g. , Frege's propositional calculus, being shown to be non-independent. Equivalence and non-equivalence of systems are discussed in the same context. The deduction theorem is proved in Chapter 3 for all the axiomatic propositional calculi in the book.




Non-Formal Education


Book Description

This is the first full study of non-formal education on an international scale since the 1980s. The book describes the emergence of the concept in the context of development and educational reform. It traces the debate about non-formal education from its origins in 1968 to the mid 1980s, and looks at the issues that this debate raised. It then describes a number of programmes in different parts of the world which call themselves ‘non-formal’, pointing out the wide range of different views about what is and what is not non-formal. Rogers asks whether we should drop the term altogether or try to reconceptualise it in terms of flexible schooling or participatory education. This is an important new book by a well-established author. It deals with complex issues, but is written in a clear style. It contains an important new analysis of the development paradigms in which the controversies surrounding non-formal education grew up, and which shaped its purpose and impacts. The author’s call for a reformulation of the concept will find echoes not only in developing societies, but also in Western circles, where the language of non-formal education is being used increasingly within the context of lifelong learning. The book grew out of the teaching of non-formal education in which Professor Rogers has been engaged for the last 20 years. It is intended for teachers and students in comparative education courses in higher education institutions, and for researchers and others with an interest in the field.




Formal Theory in Sociology


Book Description

A group of renowned sociological theorists analyze why the attempts to make sociological theory formal in the 1960s and early 1970s failed. This becomes not only an unusual and interesting analysis in the sociology of knowledge, but several of the articles move to the level of analyzing the entire discipline, explaining why positivism did not take hold and what are the distinctive characteristics of sociology as a discipline. Anyone interested in sociology as a discipline and more specifically sociological theory will find interesting analytical models.




The Post-formal Reader


Book Description

This volume argues that while twentieth century educational psychology has made important advances, a time for reassessment has arrived. Recent years have seen the rise of neo-Vygotskian analysis and situated cognition within the discipline of cognitive psychology. The authors of Post-Formal Reade have picked up where these theories leave off to more fully develop the specific connections between the social and the psychological dimensions of learning theory and educational psychology.




FME 2002: Formal Methods - Getting IT Right


Book Description

This book constitutes the refereed proceedings of the international symposium Formal Methods Europe, FME 2002, held in Copenhagen, Denmark, in July 2002. The 31 revised full papers presented together with three invited contributions were carefully reviewed and selected from 95 submissions. All current aspects of formal methods are addressed, from foundational and methodological issues to advanced application in various fields.




Introduction to Formal Languages


Book Description

Covers all areas, including operations on languages, context-sensitive languages, automata, decidability, syntax analysis, derivation languages, and more. Numerous worked examples, problem exercises, and elegant mathematical proofs. 1983 edition.




Formal Methods and Software Engineering


Book Description

This book constitutes the refereed proceedings of the 5th International Conference on Formal Engineering Methods, ICFEM 2003, held in Singapore in November 2003. The 34 revised full papers presented together with 3 invited contributions were carefully reviewed and selected from 91 submissions. The papers are organized in topical sections on testing and validation, state diagrams, PVS/HOL, refinement, hybrid systems, Z/Object-Z, Petri nets, timed automata, system modelling and checking, and semantics and synthesis.




Formal Ethics


Book Description

Formal Ethics is the study of formal ethical principles. The most important of these, perhaps even the most important principle of life, is the golden rule: "Treat others as you want to be treated". Although the golden rule enjoys support amongst different cultures and religions in the world, philosophers tend to neglect it. Formal Ethics gives the rule the attention it deserves. Modelled on formal logic, Formal Ethics was inspired by the ethical theories of Kant and Hare. It shows that the basic formal principles of ethics, like the golden rule, are very similar to principles of logic, and gives a firm basis for our ethical thinking. As an introduction to moral rationality, Formal Ethics also considers non-formal elements, and is applied to areas of practical concern such as racism and moral education




Formal Techniques for Computer Systems and Business Processes


Book Description

This book constitutes the refereed proceedings of two colocated international workshops EPEW 2005 (European Performance Engineering Workshop) and WS-FM 2005 (Web Services and Formal Methods) held in Versailles, France in September 2005. The 20 revised full papers presented were carefully reviewed and selected from 59 submissions. For EPEW 2005 only 10 papers - of the 32 submitted - were accepted for presentation; they deal with queueing theory, bounding techniques, stochastic model checking, communication schemes analysis for high-speed LAN, QOS analysis in wireless ad-hoc networks and optical networks analysis. The main topics of the 10 papers accepted for WS-FM 2005 - from 27 submissions - include: protocols and standards for WS (SOAP, WSDL, UDDI, etc.); languages and description methodologies for Choreography/Orchestration/Workflow (BPML, XLANG and BizTalk, WSFL, WS-BPEL, etc.); coordination techniques for WS (transactions, agreement, coordination services, etc.); semantics-based dynamic WS discovery services (based on Semantic Web/Ontology Techniques or other semantic theories); security, performance evaluation and quality of service of WS; semi-structured data and XML related technologies; comparisons with different related technologies/approaches.
