The generic term "graph-grammars" refers to a variety of methods for specifying (possibly infinite) sets of graphs or sets of maps. The area of graph-grammars originated in the late 60s motivated by considerations concerning pattern recognition - since then the list of areas which have interacted with the development of graph-grammars has grown quite impressively. It includes pattern recognition, software specification and development, VLSI layout schemes, data bases, lambda-calculus, analysis of concurrent systems, massively parallel computer architectures, incremental compilers, computer animation, complexity theory, developmental biology, music composition, representation of physical solids, and many others. This volume is based on the contributions presented at the third international workshop on graph-grammars and their applications, held in Warrenton, Virginia, USA in December 1986. Aiming at the best possible representation of the field not all of the papers presented at the meeting appear in this volume and some of the papers from this volume were not presented at the workshop. The volume consists of two parts: Part I presents tutorial introductions to a number of basic graph and map rewriting mechanisms. Part II contains technical contributions. This collection of papers provides the reader with an up-to-date overview of current trends in graph-grammars.

This volume, "Petri Net Technology for Communication-Based Systems," is a state-of-the-artreportin the seriesAdvances in Petri Nets. It showshowvarious well-established and new Petri net notions and techniques can be used for m- elingcommunication-basedsystems,withspecialfocusonwork?owmanagement and business processes. In the last 6 years this topic has been studied by the DFG Forschergruppe Petri Net Technology in Berlin in close cooperation with the international c- munity. The main results of this cooperation were presented at the 1st and 2nd InternationalColloquiaonPetriNetTechnologiesforModelingCommunication- Based Systems, held in Berlin in 1999 and 2001,respectively. A careful selection of contributions by members of the DFG Forschergruppe and by international experts in this ?eld are presented in this volume. Taking into account the fru- ful discussions during the two colloquia and the cross-refereeing process for the accepted papers, a high degree of common understanding was achieved, leading to a highly comprehensive presentation in this volume. The topics of the papers in this volume can be roughly classi?ed into the following two areas: - Petri net technology and - application to communication-based systems.Since most papers comprise aspects of both areas, we chose an alphabetic order. However, in the following we give a rough overview of the contributions in both areas according to the main focus of the corresponding papers.

This volume is a documentation of the main results in the research area "In- gration of Software Speci?cation Techniques for Applications in Engineering". On one hand it is based on the Priority Program "Integration von Techniken der Softwarespezi?kation fur .. ingenieurwissenschaftliche Anwendungen", short Soft- Spez,oftheGermanResearchCouncil(DFG). Ontheotherhanditcontainsnew contributions of international experts in this research area, some of which were presented at the third international workshop INT 2004 on "Integration of Sp- i?cation Techniques for Applications in Engineering". INT 2004 was launched as a satellite event of ETAPS in Barcelona, the "European Joint Conferences on Theory and Practice of Software". The Priority Program SoftSpez was initiated by W. Brauer, M. Broy, H. Ehrig, H. J. Kreowski, H. Reichel, and H. Weber concerning di?erent aspects from computer science, and by E. Schnieder and E. Westk. amper concerning two main application areas in engineering, namely "Tra?c Control Systems" and "Production Automation". After acceptance of SoftSpez by the German Research Council for the period of 1998-2004 a call for speci?c projects within this priority program was launched, where 11 projects from about 75 project proposals were accepted for a period of two years.Since 1998 each year the main research proposals and results of the projects have been presented at an annual colloquium of the priority program, and every two years the projects have been evaluated by an independent group of referees appointed by the G- man Research Council. At this point we would like to thank A.

ICGT 2004 was the 2nd International Conference on Graph Transformation, following the ?rst one in Barcelona (2002), and a series of six international workshops on graph grammars with applications in computer science between 1978 and 1998. ICGT 2004 was held in Rome (Italy), Sept. 29-Oct. 1, 2004 under the auspices of the European Association for Theoretical Computer S- ence (EATCS), the European Association of Software Science and Technology (EASST), and the IFIP WG 1.3, Foundations of Systems Speci?cation. The scope of the conference concerned graphical structures of various kinds (like graphs, diagrams, visual sentences and others) that are useful when - scribing complex structures and systems in a direct and intuitive way. These structures are often augmented with formalisms that add to the static descr- tion a further dimension, allowing for the modelling of the evolution of systems via all kinds of transformations of such graphical structures. The ?eld of graph transformation is concerned with the theory, applications, and implementation issues of such formalisms.The theory is strongly related to areas such as graph theory and graph - gorithms, formal language and parsing theory, the theory of concurrent and distributed systems, formal speci?cation and veri?cation, logic, and semantics. The application areas include all those ?elds of computer science, information processing,engineering,andthe naturalsciences wherestatic anddynamicm- elling using graphical structures and graph transformations, respectively, play important roles. In many of these areas tools based on graph transformation technology have been implemented and used.

Graphs are widely used to represent structural information in the form of objects and connections between them. Graph transformation is the rule-based manipulation of graphs, an increasingly important concept in computer science and related fields. This is the first textbook treatment of the algebraic approach to graph transformation, based on algebraic structures and category theory.Part I is an introduction to the classical case of graph and typed graph transformation. In Part II basic and advanced results are first shown for an abstract form of replacement systems, so-called adhesive high-level replacement systems based on category theory, and are then instantiated to several forms of graph and Petri net transformation systems. Part III develops typed attributed graph transformation, a technique of key relevance in the modeling of visual languages and in model transformation. Part IV contains a practical case study on model transformation and a presentation of the AGG (attributed graph grammar) tool environment. Finally the appendix covers the basics of category theory, signatures and algebras.The book addresses both research scientists and graduate students in computer science, mathematics and engineering.

ICGT 2006 was held in Natal (Rio Grande do Norte, Brazil) on September 17-23, 2006, co-located with the Brazilian Symposium on Formal Methods (SBMF 2006), under the auspices of the BrazilianComputer Society (SBC), the EuropeanAssociation of Software Science and Technology (EASST), the European Association for Theoretical Computer Science (EATCS) and the IFIP WG 1.3 on Foundations of Systems Speci?cation. The conference obtained partial support from Formal Methods Europe and IFIP TC 1 on Foundations of Computer Science. The scope of the conference concerned graphical structures of various kinds (like graphs, diagrams and visual sentences) that are useful when describing complex structures and systems in a direct and intuitive way. These structures are often enriched with formalisms that model their evolution via suitable kinds of transformations. The ?eld of the conference was concerned with the theory, applications, and implementation issues of such formalisms.

Since their introduction nearly 40 years ago, research on Petri nets has diverged in many different directions. Various classes of Petri net, motivated either by theory or applications, with its own specific features and methods of analysis, have been proposed and studies in depth.These successful developments have led to a very heterogeneous landscape of diverse models, and this, in turn, has stimulated research on concepts and approaches that contribute to unifying and structuring the diverse landscape. This state-of-the-art survey presents the most relevant approaches to unifying Petri nets in a systematic and coherent way. The 14 chapters written by leading researchers are organized in topical sections on application-oriented approaches, unifying frameworks, and theoretical approaches.

Skickas inom 10-15 vardagar
Two important new concepts, module specifications and constraints, are introduced in this second volume of a three-volume set on fundamentals of algebraic specification. These concepts are motivated by problems in practical software development and are studied here from a theoretical point of view. Modularization is one of the main structuring principles in software development. Modules and module specifications can be seen as the basic building blocks which are used in modularization of software systems and software system specification. Constraints are introduced to increase the expressive power of algebraic specifications in order to make them more useful for practical applications. The book is suitable both as a textbook for graduate courses in formal specification of data types and software systems and as a reference for researchers and system developers.

Graphs are among the simplest and most universal models for a variety of s- tems, not just in computer science, but throughout engineering and the life sciences. When systems evolve we are interested in the way they change, to p- dict, support, or react to their evolution. Graph transformation combines the idea of graphs as a universal modelling paradigm with a rule-based approach to specify their evolution. The area is concerned with both the theory of graph transformation and their application to a variety of domains. The biannual International Conferences on Graph Transformation aim at bringingtogetherresearchersandpractitionersinterestedin the foundations and applicationsof graphtransformation.The ?fth conference,ICGT 2010,was held at the University of Twente (The Netherlands) in September/October 2010, alongwith severalsatellite events.It continuedthe line ofconferences previously held in Barcelona (Spain) in 2002, Rome (Italy) 2004, Natal (Brazil) in 2006 and Leicester (UK) in 2008, as well as a series of six International Workshops on Graph Transformation with Applications in Computer Science from 1978 to 1998. Also, ICGT alternates with the workshop series on Application of Graph Transformation with Industrial Relevance (AGTIVE). The conference was held under the auspices of EATCS and EASST.

Fundamentals of Algebraic Specification 2
Module Specifications and Constraints
Häftad, Engelska, 2011

Skickas inom 10-15 vardagar
Since the early seventies concepts of specification have become central in the whole area of computer science. Especially algebraic specification techniques for abstract data types and software systems have gained considerable importance in recent years. They have not only played a central role in the theory of data type specification, but meanwhile have had a remarkable influence on programming language design, system architectures, arid software tools and environments. The fundamentals of algebraic specification lay a basis for teaching, research, and development in all those fields of computer science where algebraic techniques are the subject or are used with advantage on a conceptual level. Such a basis, however, we do not regard to be a synopsis of all the different approaches and achievements but rather a consistently developed theory. Such a theory should mainly emphasize elaboration of basic concepts from one point of view and, in a rigorous way, reach the state of the art in the field. We understand fundamentals in this context as: 1. Fundamentals in the sense of a carefully motivated introduction to algebraic specification, which is understandable for computer scientists and mathematicians. 2. Fundamentals in the sense of mathematical theories which are the basis for precise definitions, constructions, results, and correctness proofs. 3. Fundamentals in the sense of concepts from computer science, which are introduced on a conceptual level and formalized in mathematical terms.
