Electromagnetic levitation is commonly associated with transport applications, principally 'MagLev' trains. However, the technology has many potential applications across engineering, particularly where there is a requirement to improve efficiency of electrical products and devices, propelled by the desire to minimise frictional and bearing losses and ohmic losses in conductors, which are the major causes of machine inefficiency.
Fundamentals of Electromagnetic Levitation: Engineering sustainability through efficiency is an introductory text encompassing the enabling electrical technologies associated with magnetic levitation, electrostatic suspension, diamagnetic levitation and superconduction, high frequency magnetic levitation, high frequency electric suspension, and levitation using microwave pressure. It aims to make aspiring and existing electrical engineers aware of the efficiency implications of frictionless machines and hence, of how important this may be in a post-fossil fuel world in which the energy available from renewable sources is strictly limited.
Fundamentals of Ethics
John Finnis Georgetown University Press, 1983 Library of Congress BJ1012.F526 1983 | Dewey Decimal 170
Are we entitled to be confident that our moral judgements can be objective? Can they express insights into aspects of reality, rather than mere feelings, tastes, desires, decisions, upbringing, or conventions? Why must we consider some of our choices to be free, and how do our free choices matter? How far should our moral judgements be based on assessments of expected consequences? Can utilitarianism, and other consequentialist or proportionalist theories, be anything more than the rationalization of positions taken on other grounds?
The main theme of this book is the challenge to ethics from philosophical scepticism and from contemporary forms of consequentialism. But in seeking to meet this challenge, the book develops a sustained philosophical argument about many of the central questions of ethics. It reviews classical positions, and challenges some long-influential interpretations of those positions. It also reviews and participates in some recent developments and controversies in Anglo-American ethical theory.
The activity of ethical theorizing itself is shown to be a matter of free and intelligent decision, in pursuit of intelligible good; it thus provides a test-case for any ethical theory.
This is a standard reference for FAA and military air traffic control engineers and maintenance technicians focused on ground-based radar systems. With the evolution and increasing sophistication of modern radar systems, now more than ever a single-source reference is needed that contains simply understandable information on MTI, MTD, and Air Traffic Control Radar Beacon systems. There is a downside to the drive away from knowledge-based problem solving...massive increases in costs and waste inherent in the idea of lowest replaceable units. Fewer technicians are expected to manage more systems while knowing less about their equipment. This unique training and reference text will not only provide answers for day-to-day tasks, it will also help allay cost increases and waste.
Despite a prolonged slump in the housing market, the demand for residential green building remains strong. More than ever, professionals need reliable information about how to construct or retrofit livable, sustainable, and economical homes. With Fundamentals of Sustainable Dwellings, Avi Friedman provides that resource. While other books on residential green building are often either superficial or overly technical, Friedman gets it just right, delivering an illustrated, accessible guide for architects, developers, home builders, codes officials, and students of architecture and green design.
Friedman charts a new course for residential building—one in which social, cultural, economic, and environmental values are part of every design decision. The book begins with a concise overview of green building principles, covering topics such as sustainable resources and common certification methods. Each following chapter examines a critical aspect of green home construction, from siting to waste management options. Friedman provides basics about energy-efficient windows and heating and cooling systems. And he offers innovative solutions like edible landscaping and green roofs.
Friedman knows that in green building, ideas are only as good as their execution. So in each chapter valuable data is assembled and a contemporary project in which designers strove to achieve sustainability while adhering to real-world constraints is featured. The result is a practical guide for every professional in the burgeoning field of residential green building.

Tree-ring dating (dendrochronology) is a method of scientific dating based on the analysis of tree-ring growth patterns. As author James Speer notes, trees are remarkable bioindicators. Although there are other scientific means of dating climatic and environmental events, dendrochronology provides the most reliable of all paleorecords. Dendrochronology can be applied to very old trees to provide long-term records of past temperature, rainfall, fire, insect outbreaks, landslides, hurricanes, and ice storms--to name only a few events.
This comprehensive text addresses all of the subjects that a reader who is new to the field will need to know and will be a welcome reference for practitioners at all levels. It includes a history of the discipline, biological and ecological background, principles of the field, basic scientific information on the structure and growth of trees, the complete range of dendrochronology methods, and a full description of each of the relevant subdisciplines.
Individual chapters address the composition of wood, methods of field and laboratory study, dendroarchaeology, dendroclimatology, dendroecology, dendrogeomorphology, and dendrochemistry. The book also provides thorough introductions to common computer programs and methods of statistical analysis. In the final chapter, the author describes "frontiers in dendrochronology," with an eye toward future directions in the field. He concludes with several useful appendixes, including a listing of tree and shrub species that have been used successfully by dendrochronologists. Throughout, photographs and illustrations visually represent the state of knowledge in the field.
Fundamentals of Wave Phenomena
Akira Hirose The Institution of Engineering and Technology, 2010 Library of Congress QC157.H56 2010 | Dewey Decimal 531.1133
This textbook is written for use in any university course related to the physics of waves, wave theory, and electromagnetic waves in departments such as Physics, Electrical Engineering, Mechanical Engineering, Civil Engineering, and Mathematics. The only prerequisite knowledge is a course in calculus. This textbook provides a unified treatment of waves that either occur naturally or can be excited and propagated in various media. This includes both longitudinal and transverse waves. The book covers both mechanical and electrical waves, which are normally covered separately due to their differences in physical phenomena. This text focuses more on the similarities of all waves, mechanical orelectromagnetic, and therefore allows the reader to formulate a unified understanding of wave phenomena in its totality. This second edition contains extensive updates and advances in the understanding of wave phenomena since the publication of the first edition (1985). Numerous additional problems are now present and several chapters have been rewritten and combined. This is the first book in the Mario Boella Series on Electromagnetism in Information and Communication. Key features include: A unified treatment of wave phenomena; Numerical techniques using MATLAB; Both mechanical and electrical waves are described; Necessary mathematics required to understand the material summarized within; Only prerequisite is an introductory course in calculus.
Fundamentals of World Organization was first published in 1950. Minnesota Archive Editions uses digital technology to make long-unavailable books once again accessible, and are published unaltered from the original University of Minnesota Press editions.
This book offers fresh insight into the possibility of one peaceful world. It stresses pragmatic realities; it does not rest on formulation of the ideal.
Anti-democratic forces can be prevented from controlling the future course of world events only if plans are made now for a realistic world organization. The plans must be based on recognition and knowledge of all the problems involved.
Dr. Levi's approach to the broad subject of world organization is analytical, in contrast to most previous studies, which have been historical or descriptive.
With the calm, dispassionate viewpoint of a social scientist, the author upsets such common fallacies as the belief that world tension is caused primarily by clashes of ideologies or that world public opinion is effective in shaping the foreign policies of nations.
The need to improve the reliability and robustness of power systems and smart grids makes protection of sensitive equipment and power transmission and distribution lines against lightning-related effects a primary concern.

How important are foreign affairs in the grand scheme of civilization? Do defenses against the invasion of strangers influence the evolution of culture? Drawing on decades of experience in government as well as in the academy, William R. Polk offers a uniquely informed, comprehensive view of foreign relations. Bridging academic disciplines he treats foreign affairs as they occur in the real world. Instead of separating diplomacy, intelligence and espionage, defense and warfare, trade and aid, intervention and law from one another, he shows how they interact and together form a whole pattern with which we must deal if we are to move safely into the 21st century. But Neighbors and Strangers is not just a guide to the future; Polk draws upon all recorded history, and indeed upon studies of animal and primitive social behavior, and from the entire world for vivid examples to illuminate for the general reader the underlying principles and consistencies that characterize relations with foreigners.
Indeed, going deeper into the human experience, Polk documents "fear of the foreigner" as a visceral response so deep-seated and so pervasive that it transcends human memory, individual experience and even logical analysis. More generally, he shows that the tension created by having to live as neighbors with those who, in the definition of contemporaries, were irredeemably alien has been one of the major causes of the rise of civilizations.
Accessible and engaging, Neighbors and Strangers is a revelatory look at how foreign affairs are a profound reflection of human nature.
Based on scientific understanding and empirical evidence of how humans understand and interact with robotic and autonomous systems, the author reviews the concerns that have been raised around the deployment of AI and robots in human society, and the potential for disruption and harm. He explains why transparency ought to be a fundamental design consideration for Human Computer Interaction (HCI) and artificial intelligent systems. Starting with a survey of global research in the field and what transparency means in the wider context of trust, control and ethics, the author then introduces a transparent robot control architecture, and the impact of transparency using real-time displays. He presents a case study of a muttering robot, and covers current and upcoming standards for transparency, as well as future perspectives for the design, manufacture and operation of autonomous robotic systems.
Specifically, chapters cover transparency in the wider context of trust; a transparent robot control architecture, the impact of transparency using real-time displays, transparency using audio - the Muttering Robot, the effects of appearance on transparency, synthesis and further work, and several examples of Instinct reactive planner commands.
This book provides key insights into transparency in robots and autonomous systems for industry, academic researchers and engineers working on intelligent autonomous system design, human robot interaction, AI, and machine ethics. It also offers points of interest for professionals developing governmental or organisational policies and standards for the design of intelligent autonomous and AI systems, and government and standard bodies working in the emerging applications of AI.
