Book Description
This is the first comprehensive book on hypermedia and the World Wide Web that includes features of the second generation systems. Definitions, history, current technology and problems, leading-edge initiatives, future applications, all these are seen as an unfolding of a millenial communication medium that is not only serving but also involving even the non-technical person in a very technical world. Much of the promise of hypermedia lies in its applications to education, and this receives prominence in the book. The new hypermedia system HyperWave is described in detail. The book's vision, organization, and easy-to-read style make it suitable as a source of information for the practitioner and the general reader. It may also serve both as a reference book for researchers and as a textbook.

Book Description
Software systems play an increasingly important role in modern societies. Smart cards for personal identi?cation, e-banking, software-controlled me- cal tools, airbags in cars, and autopilots for aircraft control are only some examples that illustrate how everyday life depends on the good behavior of software. Consequently, techniques and methods for the development of hi- quality, dependable software systems are a central research topic in computer science. A fundamental approach to this area is to use formal speci?cation and veri?cation. Speci?cation languages allow one to describe the crucial p- perties of software systems in an abstract, mathematically precise, and implementation-independent way. By formal veri?cation, one can then prove that an implementation really has the desired, speci?ed properties. Although this formal methods approach has been a research topic for more than 30 years, its practical success is still restricted to domains in which devel- ment costs are of minor importance. Two aspects are crucial to widen the application area of formal methods: – Formal speci?cation techniques have to be smoothly integrated into the software and program development process. – The techniques have to be applicable to reusable software components. This way, the quality gain can be exploited for more than one system, thereby justifying the higher development costs. Starting from these considerations, Peter Muller ̈ has developed new te- niques for the formal speci?cation and veri?cation of object-oriented so- ware. The speci?cation techniques are declarative and implementati- independent. They can be used for object-oriented design and programming.

Book Description
This volume contains the conference proceedings of the 4th International S- posium on Leveraging Applications of Formal Methods, Veri?cation and Vali- tion, ISoLA 2010, which was held in Greece (Heraklion, Crete) October 18–21, 2010, and sponsored by EASST. Following the tradition of its forerunners in 2004, 2006, and 2008 in Cyprus and Chalchidiki, and the ISoLA Workshops in Greenbelt (USA) in 2005, in Poitiers (France) in 2007, and in Potsdam (Germany) in 2009, ISoLA 2010 p- vided a forum for developers, users, and researchers to discuss issues related to the adoption and use of rigorous tools and methods for the speci?cation, ana- sis, veri?cation, certi?cation, construction, testing, and maintenance of systems from the point of view of their di?erent application domains. Thus, the ISoLA series of events serves the purpose of bridging the gap between designers and developers of rigorous tools, and users in engineering and in other disciplines, and to foster and exploit synergetic relationships among scientists, engineers, software developers, decision makers, and other critical thinkers in companies and organizations. In particular, by providing a venue for the discussion of c- mon problems, requirements, algorithms, methodologies, and practices, ISoLA aims at supporting researchers in their quest to improve the utility, reliability, ?exibility, and e?ciency of tools for building systems, and users in their search for adequate solutions to their problems.

Book Description
This thesis is set in the field of formal methods, more precisely in the domain of deductive program verification. Our working context is the Why3 framework, a set of tools to implement, formally specify, and prove programs usingoff-the-shelf theorem provers. Why3 features a programming language,called WhyML, designed with verification in mind. An important feature of WhyML is ghost code: portions of the program that are introduced for the sole purpose of specification andverification. When it comes to get an executable implementation, ghost code is removed by an automatic process called extraction. One of the main contributions of this thesis is the formalization and implementation of Why3's extraction. The formalization consists in showing that the extracted program preserves the same operational behavior as the original source code, based on a type and effect system. The new extraction mechanism has been successfully used to get correct-by-construction OCaml modules, which are part of averified OCaml library of data structures and algorithms. This verification effort led to two other contributions of this thesis.The first is a systematic approach to the verification ofpointer-based data structures using ghost models of fragments of the heap. A fully automatic verification of a union-find data structure was achieved using this technique. The second contribution is a modular way to reason about iteration, independently of the underlying implementation. Several cursors and higher-orderiterators have been specified and verified with this approach.

Book Description
The correct development of large / com plex pieces of software demands a thorough structuring of the design process. In a first phase the requirements engineering is relevant for capturing the relevant functionality and its adequate formalization in precise mathematical definitions. Prototyping can can be used as a means for checking the functional behaviour at this early stage of development. The ade quate specification resulting from the first phase is then the basis for the second phase which comprises the derivation of an implementation. This phase requires the use of formal methods and tools to verify/validate the implementation. A prerequisite for applying this approach is to have a suitable mechanical support. This volume contains the proceedings of the International Workshop Tool Support for System Specification, Development and Verification organized June 1 - 4, 1998, in Malente, Germany. This workshop is the third in a series of events devoted to this topic. The first two workshops were held in 1994 in Kiel and 1996 in Bremen, Germany. The aim of this workshop is to provide a forum for researchers interested in the use and development of tools which support the use of mathematical techniques for the specification, development and verification of systems. The workshop covers the spectrum from verification tools to graphical editors and compilers. The program of the workshop included an invited lecture and 26 talks. The invited lecture was given by F.W. von Henke (University ofUlm) on Mechanized formal methods and system design.

Book Description
This book investigates the design of compilers for procedural languages, based on the algebraic laws which these languages satisfy. The particular strategy adopted is to reduce an arbitrary source program to a general normal form, capable of representing an arbitrary target machine. This is achieved by a series of normal form reduction theorems which are proved algebraically from the more basic laws. The normal form and the related reduction theorems can then be instantiated to design compilers for distinct target machines. This constitutes the main novelty of the author's approach to compilation, together with the fact that the entire process is formalised within a single and uniform semantic framework of a procedural language and its algberaic laws. Furthermore, by mechanising the approach using the OBJ3 term rewriting system it is shown that a prototype compiler is developed as a byproduct of its own proof of correctness.
