Containing the edited research papers resulting from an ambitious, cross-disciplinary research project, this volume examines the spatiality of virtual inhabited 3D worlds - virtual reality and cyberspace. (Three other volumes look at Interaction, Staging and Methodology.) It is about the communication spaces emerging at the Internet and supported by special 3D interfaces. It is also about the virtual spaces created by virtual reality hardware (CAVEs, panoramic screens, head mounted display systems etc.) and software. Virtual Space: Spatiality in Virtual Inhabited 3D Worlds is interdisciplinary. It deals with philosophical, psychological, communicational, technological and aesthetic aspects of space. While philosophy raises the question concerning the ontology of space - what is space - psychology deals with our perception of space. Communication theory looks at the way in which space supports communication (i.e. that space is a medium for communication), and finally aesthetic analyses exemplify the use of virtual space in virtual cities, in museums and in art.

Lars Qvortrup The world of interactive 3D multimedia is a cross-institutional world. Here, researchers from media studies, linguistics, dramaturgy, media technology, 3D modelling, robotics, computer science, sociology etc. etc. meet. In order not to create a new tower of Babel, it is important to develop a set of common concepts and references. This is the aim of the first section of the book. In Chapter 2, Jens F. Jensen identifies the roots of interaction and interactivity in media studies, literature studies and computer science, and presents definitions of interaction as something going on among agents and agents and objects, and of interactivity as a property of media supporting interaction. Similarly, he makes a classification of human users, avatars, autonomous agents and objects, demon strating that no universal differences can be made. We are dealing with a continuum. While Jensen approaches these categories from a semiotic point of view, in Chapter 3 Peer Mylov discusses similar isues from a psychological point of view. Seen from the user's perspective, a basic difference is that between stage and back-stage (or rather: front-stage), i. e. between the real "I" and "we" and the virtual, representational "I" and "we". Focusing on the computer as a stage, in Chapter 4 Kj0lner and Lehmann use the theatre metaphor to conceptualize the stage phenomena and the relationship between stage and front-stage.

On the way towards the Information Society, global networks such as the Internet, together with mobile computing, have made wide-area computing over virtual communities a reality. Digital city projects, with the goal of building platforms to support community networking, are going on worldwide. This is the first book devoted to digital cities. It is based on an international symposium held in Kyoto, Japan, in September 1999. The 34 revised full papers presented were carefully selected for inclusion in the book; they reflect the state of the art in this exciting new field of interdisciplinary research and development. The book is divided into parts on design and analysis, digital city experiments, community network experiments, applications, visualization technologies, mobile technologies, and social interaction and communityware.

Additive manufacturing has the potential to positively affect human spaceflight operations by enabling the in-orbit manufacture of replacement parts and tools, which could reduce existing logistics requirements for the International Space Station and future long-duration human space missions. The benefits of in-space additive manufacturing for robotic spacecraft are far less clear, although this rapidly advancing technology can also potentially enable space-based construction of large structures and, perhaps someday, substantially in the future, entire spacecraft. Additive manufacturing can also help to reimagine a new space architecture that is not constrained by the design and manufacturing confines of gravity, current manufacturing processes, and launch-related structural stresses. The specific benefits and potential scope of additive manufacturing remain undetermined. The realities of what can be accomplished today, using this technology on the ground, demonstrate the substantial gaps between the vision for additive manufacturing in space and the limitations of the technology and the progress that has to be made to develop it for space use. 3D Printing in Space evaluates the prospects of in-space additive manufacturing. This report examines the various technologies available and currently in development, and considers the possible impacts for crewed space operations and robotic spacecraft operations. Ground-based additive manufacturing is being rapidly developed by industry, and 3D Printing in Space discusses government-industry investments in technology development. According to this report, the International Space Station provides an excellent opportunity for both civilian and military research on additive manufacturing technology. Additive manufacturing presents potential opportunities, both as a tool in a broad toolkit of options for space-based activities and as a potential paradigm-changing approach to designing hardware for in-space activities. This report makes recommendations for future research, suggests objectives for an additive manufacturing roadmap, and envisions opportunities for cooperation and joint development.

We live in a time of great change. In the electronics world, the last several decades have seen unprecedented growth and advancement, described by Moore’s law. This observation stated that transistor density in integrated circuits doubles every 1. 5–2 years. This came with the simultaneous improvement of individual device perf- mance as well as the reduction of device power such that the total power of the resulting ICs remained under control. No trend remains constant forever, and this is unfortunately the case with Moore’s law. The trouble began a number of years ago when CMOS devices were no longer able to proceed along the classical scaling trends. Key device parameters such as gate oxide thickness were simply no longer able to scale. As a result, device o- state currents began to creep up at an alarming rate. These continuing problems with classical scaling have led to a leveling off of IC clock speeds to the range of several GHz. Of course, chips can be clocked higher but the thermal issues become unmanageable. This has led to the recent trend toward microprocessors with mul- ple cores, each running at a few GHz at the most. The goal is to continue improving performance via parallelism by adding more and more cores instead of increasing speed. The challenge here is to ensure that general purpose codes can be ef?ciently parallelized. There is another potential solution to the problem of how to improve CMOS technology performance: three-dimensional integrated circuits (3D ICs).
