The augmentation of urban spaces with technology, commonly referred to as Media Architecture, has found increasing interest in the scientific community within the last few years. At the same time architects began to use digital media as a new material apart from concrete, glass or wood to create buildings and urban structures. Simultaneously, Human-Computer Interaction (HCI) researchers began to exploit the interaction opportunities between users and buildings and to bridge the gaps between interface, information medium and architecture. As an example, they extended architectural structures with interactive, light-emitting elements on their outer shell, thereby transforming the surfaces of these structures into giant public screens. At the same time the wide distribution of mobile devices and the coverage of mobile internet allow manifold interaction opportunities between open data and citizens, thereby enabling the internet of things in the public domain. However, the appropriate distribution of information to all citizens is still cumbersome and a mutual dialogue not always successful (i.e. who gets what data and when?). In this book we therefore provide a deeper investigation of Using Information and Media as Construction Material with media architecture as an input and output medium.

Convergence proposes the enhancement of the Internet with a novel, content-centric, publish–subscribe service model based on the versatile digital item (VDI): a common container for all kinds of digital content, including digital representations of real-world resources. VDIs will serve the needs of the future Internet, providing a homogeneous method for handling structured information, incorporating security and privacy mechanisms. CONVERGENCE subsumes the following areas of research: · definition of the VDI as a new fundamental unit of distribution and transaction; · content-centric networking functionality to complement or replace IP-address-based routing; · security and privacy protection mechanisms; · open-source middleware, including a community dictionary service to enable rich semantic searches; · applications, tested under real-life conditions. This book shows how CONVERGENCE allows publishing, searching and subscribing to any content. Creators can publish their content by wrapping it and its descriptions into a VDI, setting rights for other users to access this content, monitor its use, and communicate with people using it; they may even update or revoke content previously published. Access to content is more efficient, as search engines exploit VDI metadata for indexing, and the network uses the content name to ensure users always access the copy closest to them. Every node in the network is a content cache; handover is easy; multicast is natural; peer-to-peer is built-in; time/space-decoupling is possible. Application developers can exploit CONVERGENCE’s middleware and network without having to resort to proprietary/ad hoc solutions for common/supporting functionality. Operators can use the network more efficiently, better controlling information transfer and related revenues flows. Network design, operation and management are simplified by integrating diverse functions and avoiding patches and stopgap solutions. Whether as a text for graduate students working on the future of the Internet, or a resource for practitioners providing e-commerce or multimedia services, or scientists defining new technologies, CONVERGENCE will make a valuable contribution to the future shape of the Internet.

Model-Driven Development (MDD) has become an important paradigm in software development. It uses models as primary artifacts in the development process. This book provides an outstanding overview as well as deep insights into the area of model-driven development of user interfaces, which is an emerging topic in the intersection of Human-Computer-Interaction and Software-Engineering. The idea of this book is based on the very successful workshop series of "Model-Driven Development of Advanced User Interfaces (MDDAUI)". It has been written by the leading researchers and practitioners in the field of model-driven development of user interfaces and offer a variety of solutions and examples for * Architectures and environments for the generation of user interfaces * User interface development for specific domains and purposes * Model-driven development in the context of ambient intelligence * Concepts supporting model-driven development of user interfaces

ETAPS 2001 is the fourth instance of the European Joint Conferences on Theory and Practice of Software. ETAPS is an annual federated conference that was established in 1998 by combining a number of existing and new conferences. This year it comprises ve conferences (FOSSACS, FASE, ESOP, CC, TACAS), ten satellite workshops (CMCS, ETI Day, JOSES, LDTA, MMAABS, PFM, RelMiS, UNIGRA, WADT, WTUML), seven invited lectures, a debate, and ten tutorials. The events that comprise ETAPS address various aspects of the system - velopment process, including speci cation, design, implementation, analysis and improvement. The languages, methodologies and tools which support these - tivities are all well within its scope. Di erent blends of theory and practice are represented, with an inclination towards theory with a practical motivation on one hand and soundly-based practice on the other. Many of the issues involved in software design apply to systems in general, including hardware systems, and the emphasis on software is not intended to be exclusive.

In this book, Hussmann builds a bridge between the pragmatic methods for the design of information systems and the formal, mathematical background. Firstly, the principal feasibility of an integration of the different methods is demonstrated. Secondly, the formalism is used as a systematic semantic analysis of the concepts in SSADM, a British standard structured software engineering method. Thirdly, a way of obtaining a hybrid formal-pragmatic specification using a combination of SSADM notations and formal (SPECTRUM) specifications is shown. This well-written book encourages scientists and software engineers to apply formal methods to practical software development problems.

Der dritte Workshop "Software Engineering im Unterricht der Hochschulen (SEUH)" findet am 24. und 25. Februar 1994 in Munchen statt. Nach zwei SEUH- Workshops (1992 Stuttgart, 1993 Hamburg), in denen ein Erfahrungsaustausch auf breiter Basis im Vordergrund stand, behandelt dieser Workshop zusatzlich zu der Diskussion uber didaktische Konzepte das Schwerpunktthema "Anforderungen an SEUH aus Sicht der Industrie". Um dieses Thema kompetent diskutieren zu koennen, wurden Referenten aus verschiedenen Firmen eingeladen, die Erfahrungen mit der Integration von Hochschulabsolventen in die betriebliche Prws haben (W. Altrnann (K&A), U. Bittner (START), R. Haggenmuller (SNI), G. Mathy (Allianz), J. Wolle (Rohde & Schwarz)). Weitere wichtige Themen werden in zwei Arbeitsgruppen behandelt, denen auf diesem Workshop viel Zeit eingeraumt wird. Ziel der Arbeitsgruppen ist es, einen Entwurf eines Software-Engineering-Curriculums und Handlungsempfehlungen zum Einsatz von CASE-Werkzeugen in der Lehre zu erarbeiten. In beiden Fallen ist das Ergebnis der Diskussion als Grundlage fur eine kontinuierliche Zusammenarbeit uber den Workshop hinaus gedacht. Dieser Tagungsband enthalt zu beiden Arbeitsgruppen jeweils eine "Agenda", die als Diskussionsgrundlage dienen soll sowie schriftliche Ausarbeitungen von Kurzvortragen in der jeweiligen Gruppe. Den organisatorischen Rahmen dieses Workshops bildeten wieder die GI- Fachgruppen 2.1.1 (Software Engineering) und 4.3.1 (Requirements Engineering) sowie das German Chapter of the ACM. Mitglieder des Programmkomitees waren: H. Hussmann (TU Munchen), E. Jaus (Ploenzke Informatik), B. Paech (TU Munchen), J. Raasch (FH Hamburg), G.
