Book Description
The notion of time plays an important role in modern science. In computer science and artificial intelligence, the parameter of time is of particular importance, e.g. for planning robot activity, natural language processing, and time-varying scene analysis. This work investigates the relationship between classic, first-order theories of point- and interval-based time structures, modal logics of corresponding structures, and their algorithmic representations. To make this relationship complete, a formalisation of Allen's famous algorithm, applicable to various structures of time, is presented along with its translation to modal logics. All in all, the book is a competent and comprehensive analysis of logical descriptions and algorithmic representations of time structures.

Book Description
This volume contains the proceedings of a NATO Advanced study Institute held at Geilo, Norway between 2 - 12 april 1991. This institute was the eleventh in a series held biannually at Geilo on the subject of phase transitions. It was intended to capture the latest ideas on selforgan ized patterns and criticality. The Institute brought together many lecturers, students and active re searchers in the field from a wide range of NATO and non-NATO countries. The main financial support came from the NATO scientific Affairs Divi sion, but additional support was obtained from the Norwegian Research Council for Science and the Humanities (NAVF) and Institutt for energi teknikk. The organizers would like to thank all these contributors for their help in promoting an exciting and rewarding meeting, and in doing so are confident that they echo the appreciation of all the parti cipants. In cooperative, equilibrium systems, physical states are described by spatio-temporal correlation functions. The intimate connection between space and time correlations is especially apparent at the critical point, the second order phase transition, where the spatial range and the decay time of the correlation function both become infinite. The salient features of critical phenomena and the history of the devel opment of this field of science are treated in the first chapter of this book.

Book Description
Electroacoustic music, a flourishing medium for over half a century, remains today, in a wide array of technological forms, one of the major areas of creative activity in music. However, it has long been overlooked in theoretical studies—possibly in part because it does away with traditional scores and notation. In this landmark collection, a group of distinguished composers and theorists who have actively worked in the field present detailed analyses of important electroacoustic works while also demonstrating some recent approaches to the analysis of the music of this medium. Included here are discussions of such significant works as Karlheinz Stockhausen's Gesang der Jünglinge (1955/56), Iannis Xenakis' Diamorphoses (1957), and Jean-Claude Risset's Contours (1982). Overall, the collection aims to elucidate the sonic design of each of the electroacoustic music works under investigation, using its best examples as a lens through which to examine an unduly neglected genre. Demonstrating recent techniques in the analysis of electroacoustic music, the volume also considers various compositional approaches as well as computer applications that have become an irreplaceable tool in the composing of this music. So little has been written about this 20th-century art form that Electroacoustic Music: Analytical Perspectives is at once a fresh, bold step forward in musicology and analysis.

Book Description
The volume offers a comprehensive introduction to the sociology of time. Based on selected contributions from leading writers, it illustrates the range of issues and perspectives which define the field. The volume traces distinct traditions of time analysis in social science and uses these to explain, for example, the development of capitalist time-consciousness, the ways we structure time in organizations and institutions, and how our time perceptions change in line with changes in culture. The book is for those who wish to understand how time comes to condition our everyday actions and affairs.

Book Description
By making use of the principles of systems science, the scientific community can explain many complicated matters of the world and shed new light on unsettled problems. Each real science has its own particular methodology for not only qualitative but also quantitative analyses, so it is important to understand the organic whole of systems research with operable mathematical methods. Systems Science: Methodological Approaches presents a mathematical explanation of systems science, giving readers a complete technical formulation of different systemic laws. It enables them to use a unified methodology to attack different problems that are hard, if not impossible, for modern science to handle. Following a brief history of systems science, the book explores: Basic concepts, characteristics, properties, and classifications of general systems Nonlinear systems dynamics and the theory of catastrophe Dissipative structures and synergistics Studies of chaos, including logistic mapping, phase space reconstruction, Lyapunov exponents, and chaos of general single relation systems Different aspects and concepts of fractals, including a presentation of L systems analysis and design Complex systems and complexity, with a discussion of how the phenomena of "three" and complexity are related, and how various cellular automata can be constructed to generate useful simulations and figurative patterns Complex adaptive systems and open complex giant systems, with introduction of the yoyo model and practical applications Complex networks and related concepts and methods The book concludes with several case studies that demonstrate how various concepts and the logic of systems can be practically applied to resolve real-life problems, such as the prediction of natural disasters. The book will be useful in directing future research and applications of systems science on a commonly accepted platform and playground.

Book Description
Thanks to Einstein's relativity theories, our notions of space and time underwent profound revisions about a 100 years ago. The resulting interplay between geometry and physics has dominated all of fundamental physics since then. This volume contains contributions from leading researchers, worldwide, who have thought deeply about the nature and consequences of this interplay. The articles take a long-range view of the subject and distill the most important advances in broad terms, making them easily accessible to non-specialists. The first part is devoted to a summary of how relativity theories were born (J Stachel). The second part discusses the most dramatic ramifications of general relativity, such as black holes (P Chrusciel and R Price), space-time singularities (H Nicolai and A Rendall), gravitational waves (P Laguna and P Saulson), the large scale structure of the cosmos (T Padmanabhan); experimental status of this theory (C Will) as well as its practical application to the GPS system (N Ashby). The last part looks beyond Einstein and provides glimpses into what is in store for us in the 21st century. Contributions here include summaries of radical changes in the notions of space and time that are emerging from quantum field theory in curved space-times (Ford), string theory (T Banks), loop quantum gravity (A Ashtekar), quantum cosmology (M Bojowald), discrete approaches (Dowker, Gambini and Pullin) and twistor theory (R Penrose).

Book Description
Our body's clocks make the difference between happiness and depression, health and illness, and even life and death. The brilliant scientist Paul Kelley makes a compelling case for all organisations to allow people to work and study the hours that suit their personal circadian rhythms. That way, Paul argues, we would all be more productive, a great deal of ill health would be avoided and the world would be a better and happier place.
