Zusammenfassung: This textbook concentrates on processes, activities and results related to software architectures. It describes the separation of architecture artefacts corresponding to their nature, their logical or their modeling level on one hand and at the same time emphasizes their integration based on their mutual relations. Design or development processes demand for integration, as different artifacts must be elaborated, which are mutually dependent and need to be in a consistent form. The book is structured in four parts. The introductory Part I deals with the relevance of architectures, the central role of the design subprocess both in development or maintenance, and the importance of the decisions and artefacts in the overall result. Another topic is the spectrum of views an architecture language has to offer, and that there are different architectures to be regarded, from abstract and static to detailed, technical, and specific. Part II then discusses "important topics" on the architecture level. It deals with adaptability especially for embedded systems, with integrating styles/ pattern notations, with different reuse forms and how to find them, with the role of architectures for integrating different existing systems, and with reverse and reengineering of legacy systems. Next, Part III covers architecture modeling and its relation to surrounding activities, as well as architectures to surrounding other results. The single chapters are on transformation between requirements and architectures, architectures and programming, architectures and project management and organization, as well as architectures and their relations to quality assurance or documentation. Eventually, Part IV summarizes the main messages and presents open problems, both for every single chapter and across chapters. Every chapter focuses on a specific problem it addresses, a question it answers, the attention it demands, a message it conveys, and further open questions it raises. The chapters are mostly independent, which implies a certain redundancy, yet it allows lecturers (and their students) to either use the book as the basis of teaching software architecture or design, or to just pick those aspects that need special attention in a more advanced course
This book shows how children's work can take on widely differing forms; and how it can both harm and benefit children. Differing in approach from most other work in the field, it endeavours to understand working children from their own perspective.
Software engineering research has di?erent pro?les in Europe and North Am- ica.WhileinNorthAmericathere isalotofknowhowinthepractical,technical, and organizational aspects of software engineering, in Europe the work conc- trates more on foundations and formal modeling of software engineering issues. Bothapproacheshavetheirindividualstrengthsandweaknesses. Researchdriven solelyby practice insoftware engineering runs in the danger ofdevelopinginto a shallow ?eld failing to ?nd a solid scienti?c basis or to contribute substantially to the progress in software engineering. Work concentrating on formal aspects alone is in the danger of becoming too theoretical and isolated from practice so that any transfer into practical application will fail. Substantial progress in software engineering can be achieved, however, by bringing together pragmatic and foundational work in software engineering - search. This can provide a step towards a common scienti?c basis for software engineering that allows us to integrate the various research results, leading to fruitful synergetic e?ects. It will also help to identify critical research paths and to develop an adequate paradigm for the scienti?c discipline of software en- neering. In software and systems engineering it is necessary to distinguish the en- mous di?erence between the dynamics in development we refer to and the l- ited scope assumed by manyof today’ssoftware managerswho stilluse outdated techniques. Many of the unsolved problems associated with the old techniques are symptoms of a lack of formalization and a lack of automation support. It was the goal of this workshop to bring together experts from science and practice in software and systems engineering from North America and Europe.
Hauke provides a tour de force study of the history and basic characteristics of modern feminism. Hauke presents an objective, detailed study of the facts of feminist theology around the world, using their own words and writings. He looks at the distinctiveness of feminist theology, what its image of man is as a fundamental point of departure, its basis from the experience of women as "formal principle", its views of the image of God, Christ, Mary, the Church, liturgy, ecology and eschatology. After carefully describing what the feminist position is, Hauke gives a critique from the point of view of the Catholic tradition. "The purpose of the present work is to provide, not a kind of "encyclopedia" on feminist theology, but an introduction and representative survey of central themes that will enable one to form a personal opinion. Addressed here are not just specialists in theology but all women and men who desire to inform themselves further about the powerful historical current that is feminist theology." -Manfred Hauke
Vienna's historical center was recently named a UNESCO World Heritage landmark, and Manfred Wehdorn's new guide takes the visitor on a tour of the historical streets and busy urban squares as well as the quiet hidden courtyards that make Vienna unique. This architecturally and culturally rich metropolis comes alive as the stories behind the buildings and palacesnbsp;-- their builders, architects, and often illustrious inhabitantsnbsp;-- are revealed in Wehdorn's illuminating text. The guide itself is a useful and systematic compendium containing fifty maps that make navigating the city and locating the individual sites a breeze. For anyone interested in, or planning to visit, this beloved European capital, Vienna: A City Guide is essential reading.
This fascinating book explores the connections between chaos theory, physics, biology, and mathematics. Its award-winning computer graphics, optical illusions, and games illustrate the concept of self-similarity, a typical property of fractals. The author -- hailed by Publishers Weekly as a modern Lewis Carroll -- conveys memorable insights in the form of puns and puzzles. 1992 edition.
In today’s dynamic business world, the success of a company increasingly depends on its ability to react to changes in its environment in a quick and flexible way. Companies have therefore identified process agility as a competitive advantage to address business trends like increasing product and service variability or faster time to market, and to ensure business IT alignment. Along this trend, a new generation of information systems has emerged—so-called process-aware information systems (PAIS), like workflow management systems, case handling tools, and service orchestration engines. With this book, Reichert and Weber address these flexibility needs and provide an overview of PAIS with a strong focus on methods and technologies fostering flexibility for all phases of the process lifecycle (i.e., modeling, configuration, execution and evolution). Their presentation is divided into six parts. Part I starts with an introduction of fundamental PAIS concepts and establishes the context of process flexibility in the light of practical scenarios. Part II focuses on flexibility support for pre-specified processes, the currently predominant paradigm in the field of business process management (BPM). Part III details flexibility support for loosely specified processes, which only partially specify the process model at build-time, while decisions regarding the exact specification of certain model parts are deferred to the run-time. Part IV deals with user- and data-driven processes, which aim at a tight integration of processes and data, and hence enable an increased flexibility compared to traditional PAIS. Part V introduces existing technologies and systems for the realization of a flexible PAIS. Finally, Part VI summarizes the main ideas of this book and gives an outlook on advanced flexibility issues. The book’s target groups include researchers, PhD students and Master students in the field of information systems. After reading the book, they will better understand PAIS flexibility aspects. To support the easy use as a textbook, a series of exercises is provided at the end of each chapter and slides and further teaching material are available on the book’s web site www.flexible-processes.com. Professionals specializing in business process management (BPM) who want to obtain a good understanding of flexibility challenges in BPM and state-of-the-art solutions will also benefit from the presentations of open source as well as commercial process management systems and related practical scenarios.

The papers are organized in topical sections on Web applications; data structures and data bases; engineering applications; agent-oriented and functional programs and distribution; object- and aspect-oriented systems; natural languages: processing and structuring; reengineering; reuse and integration; modeling languages; bioinformatics; and multimedia, picture, and visual languages.
During its 30-year existence, the International Workshop on Graph-Theoretic Concepts in Computer Science has become a distinguished and high-quality computer science event. The workshop aims at uniting theory and practice by demonstrating how graph-theoretic concepts can successfully be applied to v- ious areas of computer science and by exposing new theories emerging from applications. In this way, WG provides a common ground for the exchange of information among people dealing with several graph problems and working in various disciplines. Thereby, the workshop contributes to forming an interdis- plinary research community. The original idea of the Workshop on Graph-Theoretic Concepts in C- puter Science was ingenuity in all theoretical aspects and applications of graph concepts, wherever applied. Within the last ten years, the development has strengthened in particular the topic of structural graph properties in relation to computational complexity. This workshop has become pivotal for the c- munity interested in these areas.An aimspeci?c to the 30thWG was to support the central role of WG in both of the prementioned areas on the one hand and on the other hand to promote its originally broader scope. The 30th WG was held at the Physikzentrum Bad Honnef, which serves as the main meeting point of the German Physical Society. It o?ers a secluded setting for research conferences, seminars, and workshops, and has proved to be especiallystimulatingforfruitful discussions.Talksweregiveninthenewlecture hall with a modern double rear projection, interactive electronic board, and full video conferencing equipment.
