Since the turn of this century (and even earlier), a plethora of projects have arisen to promise us bold new interactive adventures and immersive travel into the past with digital environments (using mixed, virtual or augmented reality, as well as computer games). In Playing with the Past: Into the Future Erik Champion surveys past attempts to communicate history and heritage through virtual environments and suggests new technology and creative ideas for more engaging and educational games and virtual learning environments.This second edition builds on and updates the first edition with new game discussions, surveys, design frameworks, and theories on how cultural heritage could be experienced in digital worlds, via museums, mobile phones, or the Metaverse. Recent games and learning environments are reviewed, with provocative discussion of new and emerging promises and challenges.

Mit Fertigungsinseln wird eine interessante M|glichkeit zur wirtschaftlichenund humanen Gestaltung des Fertigungsbereiches vorgestellt, die zunehmenden Eingang in die industrielle Einzel-, Klein- und Mittelserienfertigung findet. Dabei wendet sich dieser Band vornehmlich an kleine und mittlere Unternehmen, denn er zeigt Wege, bei geringem Investment mittels Nutzung fortschrittlicher betrieblicher Informationstechnik zu leistungsf{higen Organistionsstrukturen zu gelangen. Fertigungsinseln als Organisationsform versprechen bei h|herer Termintreue eine Verringerung der Durchlaufzeiten und eine Verbesserung der Fertigungsqualit{t. Dieses Buch betrachtet Fertigungsinseln aber nicht nur als isolierte betriebliche Organisationsstruktur. Es werden vielmehr M|glichkeiten der Integration in }bergeordnete CIM-Strukturen aufgezeigt, wobei der Koordination mehrerer Inseln besondere Bedeutung zukommt. Neben den grundlegenden Ausf}hrungen zum Thema macht eine Reihe vonrealisierten Beispielen das Buch zum Handwerkszeug f}r den industriellen Praktiker.

This book not only presents the state-of-the-art research on knowledge modelling, knowledge retrieval and knowledge reuse, but also elaborates the Collaborative Knowledge Management (CKM) paradigm and the architecture for the next generation of knowledge management systems. Although knowledge management has been extensively studied, particularly in the fields of business management and engineering design, there is a lack of systematic methodologies for addressing the integrated and collaborative dimension of knowledge management during the collaborative process of designing and developing complex systems, products, processes and services. The rapid development of information technologies, together with their applications in engineering and management, has laid the foundation for a Collaborative Knowledge Management (CKM) paradigm. The book specifically discusses this paradigm from a computational perspective.By exploring specific research findings underpinning further CKM research and applications and describing methods related to hot research topics and new research areas, the book appeals to professionals, researchers and graduate students who are interested in knowledge management and related topics and who have a basic understanding of information technologies, computational methods, and knowledge management.

In recent years, both Networks-on-Chip, as an architectural solution for high-speed interconnect, and power consumption, as a key design constraint, have continued to gain interest in the design and research communities. This book offers a single-source reference to some of the most important design techniques proposed in the context of low-power design for networks-on-chip architectures.

SEAFOOD 2009: Enabling Global Partnerships to Deliver on Business Needs Companies have been outsourcing areas of software development work for many years, either because of the engineering challenges or because the outsourced aspect is not central to their core business. A profound transformation has been a?ecting this model over recent years: a massive transfer of development - tivities from the USA and Europe to a skilled labor force in service-providing countries. This transformation has been driven by the demands of a global bu- ness climate seeking to increase the value delivery of IT investment. However, the ability to realize this value can prove problematic in practice. Of particular concern are the hidden costs of globally distributed models of working, such as understanding and communicating the true business needs across organizational and cultural boundaries. To address such issues, o?shore outsourcing requires di?erent support from in-housedevelopmentandthismeansadaptingfamiliartechniques,processesand tools to this setting, as well as perhaps creating innovative new ones. Coupled with this industry transformation there is hence a pressing need to re-examine thosesoftwareengineeringapproachesthateither facilitate orimpede this model of working. With an inevitable focus on the economy in 2009, business decisions regarding the sourcing of software development projects will come under close scrutiny. It will become increasingly critical to design global partnerships that both clarify cost/bene?ts and enable delivery on business needs.

We are presently observing a paradigm change in designing complex SoC as it occurs roughly every twelve years due to the exponentially increasing number of transistors on a chip. This design discontinuity, as all previous ones, is characterized by a move to a higher level of abstraction. This is required to cope with the rapidly increasing design costs. While the present paradigm change shares the move to a higher level of abstraction with all previous ones, there exists also a key difference. For the ?rst time shrinking geometries do not leadtoacorrespondingincreaseofperformance. InarecenttalkLisaSuofIBM pointed out that in 65nm technology only about 25% of performance increase can be attributed to scaling geometries while the lion share is due to innovative processor architecture [1]. We believe that this fact will revolutionize the entire semiconductor industry. What is the reason for the end of the traditional view of Moore's law? It is instructive to look at the major drivers of the semiconductor industry: wireless communications and multimedia. Both areas are characterized by a rapidly increasingdemandofcomputationalpowerinordertoprocessthesophisticated algorithmsnecessarytooptimallyutilizethepreciousresourcebandwidth. The computational power cannot be provided by traditional processor architectures and shared bus type of interconnects. The simple reason for this fact is energy ef?ciency: there exist orders of magnitude between the energy ef?ciency of an algorithm implemented as a ?xed functionality computational element and of a software implementation on a processor.
