This book provides a comprehensive overview of magnetic levitation (Maglev) technologies, from fundamental principles through to the state-of-the-art, and describes applications both realised and under development. It includes a history of Maglev science and technology showing the various milestones in its advancement. The core concepts, operating principles and main challenges of Maglev applications attempted across various fields are introduced and discussed. The principle difficulties encountered when applying Maglev technology to different systems, namely air gap control and stabilization, are addressed in detail. The book describes how major advancements in linear motor and magnet technologies have enabled the development of the linear-motor-powered Maglev train, which has a high speed advantage over conventional wheeled trains and has the potential to reach speed levels achieved by aircraft. However, many expect that Maglev technology to be a green technology that is applied not only in rail transportation, but also in diverse other fields; to ensure clean transfer in LCD manufacturing, in ropeless high speed elevators, small capacity rail transportation, space vehicle launchers, missile testers, energy storage, and so on. These potential applications and their unique challenges and proposed technological solutions are introduced and discussed in depth. The book will provide readers from academia, research institutes and industry with insights on where and how to apply Maglev technology, and will serve as a guide to the realization of their Maglev applications.

A century ago, Celtic groups descending from the famed Hermetic Order of the Golden Dawn pioneered a fascinating form of ceremonial magic invoking Pagan Celtic powers instead of relying on the more commonly used Judeo-Christian names and symbols. Those groups disappeared many decades ago, and their teachings were lost. But today, their legacy has been reborn. Respected occult author and Grand Archdruid John Michael Greer has re-created a complete magical system based on the Celtic Golden Dawn traditions. This new book provides students with a complete curriculum of Druidical magic and occult wisdom, including training in ceremonial magic, meditation, pathworking, divination, geomancy, and herbal alchemy, allowing self-initiation into the three degrees of Ovate, Bard, and Druid. Structured to resemble a long-lost correspondence course, The Celtic Golden Dawn presents a series of knowledge lectures, meditations, and rituals leading to mastery of the most important magical techniques.

Has the future a future? Are we bringing history to an end? Observing any one of several individual but critical trends suggests that, without rapid and positive action, history may have only a very short way to run. Whether it is the growth of world population, of greenhouse gas concentrations and the accelerating rate of climate change, the running down of oil and natural gas reserves, growing shortages of fresh water for agriculture, industry and domestic use, or the increasing difficulty in controlling epidemic diseases we are facing a mounting global crisis that will peak in less than a generation, around the year 2030. Taken together, these trends point to a potentially apocalyptic period, if not for the planet itself then certainly for human societies and for humankind. In this compelling book, and update to The 2030 Spike, Colin Mason explains in clear and irrefutable terms what is going on largely below the surface of our daily or weekly news bulletins. The picture he paints is stark, and yet it is not bleak. Being forewarned, we are forearmed, and he draws on his own extensive political experience to describe how much we can do as individuals, and above all collectively, not merely to avert crisis but to engineer thoroughgoing change that can usher in genuinely sustainable and valuable alternatives to the way we live now.

This book features the latest advances and future trends in water science and technology. It also discusses the scientific popularization and quantitative resolution of a variety of mysterious properties of water and ice from the perspective of hydrogen-bond cooperativity in response to stimuli such as chemical contamination, electrification, magnetification, mechanical compression, molecular undercoordination, and thermal excitation. Anomalies include the floating of ice, the Hofmeister effect in solutions, regelation of ice, slipperiness of ice, water’s tough skin, the Mpemba paradox, and the floating bridge. It also addresses the superfluidity of microchannels, hydrogen bond potentials, nanodroplet and bubble thermodynamics, quasisolidity and supersolidity, controlling superhydrophobicity–superhydrophilicity transition, and high-pressure ice formation. The target audience for this book includes students, senior scholars, engineers and practitioners in the area of physical chemistry, biology, as well as aqueous and colloid solutions.

This book shows how transit assignment models can be used to describe and predict the patterns of network patronage in public transport systems. It provides a fundamental technical tool that can be employed in the process of designing, implementing and evaluating measures and/or policies to improve the current state of transport systems within given financial, technical and social constraints. The book offers a unique methodological contribution to the field of transit assignment because, moving beyond “traditional” models, it describes more evolved variants that can reproduce:• intermodal networks with high- and low-frequency services;• realistic behavioural hypotheses underpinning route choice;• time dependency in frequency-based models; and• assumptions about the knowledge that users have of network conditionsthat are consistent with the present and future level of information that intelligent transport systems (ITS) can provide. The book also considers the practical perspective of practitioners and public transport operators who need to model and manage transit systems; for example, the role of ITS is explained with regard to their potential in data collection for modelling purposes and validation techniques, as well as with regard to the additional data on network patronage and passengers’ preferences that influences the network-management and control strategies implemented. In addition, it explains how the different aspects of network operations can be incorporated in traditional models and identifies the advantages and disadvantages of doing so. Lastly, the book provides practical information on state-of-the-art implementations of the different models and the commercial packages that are currently available for transit modelling. Showcasing original work done under the aegis of the COST Action TU1004 (TransITS), the book provides a broad readership, ranging from Master and PhD students to researchers and from policy makers to practitioners, with a comprehensive tool for understanding transit assignment models.
