This book was released on 2012-10-09 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: Clear presentation of a new control process applied to induction machine (IM), surface mounted permanent magnet synchronous motor (SMPM-SM) and interior permanent magnet synchronous motor (IPM-SM) Direct Eigen Control for Induction Machines and Synchronous Motors provides a clear and consise explanation of a new method in alternating current (AC) motor control. Unlike similar books on the market, it does not present various control algorithms for each type of AC motor but explains one method designed to control all AC motor types: Induction Machine (IM), Surface Mounted Permanent Magnet Synchronous Motor (SMPM-SM) (i.e. Brushless) and Interior Permanent Magnet Synchronous Motor (IPM-SM). This totally new control method can be used not only for AC motor control but also to control input filter current and voltage of an inverter feeding an AC motor. Accessible and clear, describes a new fast type of motor control applied to induction machine (IM), surface mounted permanent magnet synchronous motor (SM-PMSM) and interior permanent magnet synchronous motor (I-PMSM) with various examples Summarizes a method that supersedes the two known direct control solutions – Direct Self Control and Direct Torque Control – to be used for AC motor control and to control input filter current and voltage of an inverter feeding an AC motor Presents comprehensive simulations that are easy for the reader to reproduce on a computer. A control program is hosted on a companion website This book is straight-forward with clear mathematical description. It presents simulations in a way that is easy to understand and to reproduce on a computer, whilst omitting details of practical hardware implementation of control, in order for the main theory to take focus. The book remains concise by leaving out description of sensorless controls for all motor types. The sections on “Control Process”, “Real Time Implementation” and “Kalman Filter Observer and Prediction” in the introductory chapters explain how to practically implement, in real time, the discretized control with all three types of AC motors. In order, this book describes induction machine, SMPM-SM, IPM-SM, and, application to LC filter limitations. The appendixes present: PWM vector calculations; transfer matrix calculation; transfer matrix inversion; Eigen state space vector calculation; and, transition and command matrix calculation. Essential reading for Researchers in the field of drive control; graduate and post-graduate students studying electric machines; electric engineers in the field of railways, electric cars, plane surface control, military applications. The approach is also valuable for Engineers in the field of machine tools, robots and rolling mills.

Download or read book Orientalism written by Edward W. Said and published by Vintage. This book was released on 2014-10-01 with total page 434 pages. Available in PDF, EPUB and Kindle. Book excerpt: A groundbreaking critique of the West's historical, cultural, and political perceptions of the East that is—three decades after its first publication—one of the most important books written about our divided world. "Intellectual history on a high order ... and very exciting." —The New York Times In this wide-ranging, intellectually vigorous study, Said traces the origins of "orientalism" to the centuries-long period during which Europe dominated the Middle and Near East and, from its position of power, defined "the orient" simply as "other than" the occident. This entrenched view continues to dominate western ideas and, because it does not allow the East to represent itself, prevents true understanding.

Download or read book Dimensions of Personality written by Martin Rein and published by Routledge. This book was released on 2018-02-06 with total page 406 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the original work on which Hans Eysenck's fifty years of research have been built. It introduced many new ideas about the nature and measurement of personality into the field, related personality to abnormal psychology, and demonstrated the possibility of testing personality theory experimentally. The book is the result of a concentrated and cooperative effort to discover the main dimensions of personality, and to define them operationally, that is, by means of strictly experimental, quantitative procedures. More than three dozen separate researches were carried out on some 10,000 normal and neurotic subjects by a research team of psychologists and psychiatrists. A special feature of this work is the close collaboration between psychologists and psychiatrists. Eysenck believes that the exploration of personality would have reached an advanced state much earlier had such a collaboration been the rule rather than the exception in studies of this kind. Both disciplines benefit by working together on the many problems they have in common. In his new introduction, Eysenck discusses the difficulty he had in conveying this belief to scientists from opposite ends of the psychology spectrum when he first began work on this book. He goes on to explain the basis from which Dimensions of Personality developed. Central to any concept of personality, he states, must be hierarchies of traits organized into a dimensional system. The two major dimensions he posited, neuroticism and extraversion, were in disfavor with most scientists of personality at the time. Now they form part of practically all descriptions of personality. Dimensions of Personality is a landmark study and should be read by both students and professionals in the fields of psychiatry, psychology, and sociology.

Download or read book Time in the Philosophy of Gabriel Marcel written by Helen Tattam and published by MHRA. This book was released on 2013 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gabriel Marcel (1889-1973) stands outside the traditional canon of twentieth-century French philosophers. Where he is not simply forgotten or overlooked, he is dismissed as a 'relentlessly unsystematic' thinker, or, following Jean-Paul Sartre's lead, labelled a 'Christian existentialist' - a label that avoids consideration of Marcel's work on its own terms. How is one to appreciate Marcel's contribution, especially when his oeuvre appears to be at odds with philosophical convention? Helen Tattam proposes a range of readings as opposed to one single interpretation, a series of departures or explorations that bring his work into contact with critical partners such as Henri Bergson, Paul Ricoeur and Emmanuel Lévinas, and offer insights into a host of twentieth-century philosophical shifts concerning time, the subject, the other, ethics, and religion. Helen Tattam's ambitious study is an impressively lucid account of Marcel's engagement with the problem of time and lived experience, and is her first monograph since the award of her doctorate from the University of Nottingham.
Download or read book State of World Aquaculture 2006 written by Food and Agriculture Organization of the United Nations. Inland Water Resources and Aquaculture Service and published by Food & Agriculture Org.. This book was released on 2006 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aquaculture is developing, expanding and intensifying in almost all regions of the world, except in sub-Saharan Africa. Although the sector appears to be capable of meeting the gap between future demand and supply for aquatic food, there are many constraints and challenges which must be addressed in order to at least maintain the present level of per capita consumption at the global level. Key issues are the need for enhanced enforcement of regulation and better governance of the sector, as well as greater producer participation in the decision-making and regulation process. This publication examines past trends in aquaculture development as well as the current global status, drawing on a number of national and regional reviews.
Download or read book Science Technology and Warfare written by Monte D. Wright and published by . This book was released on 1971 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: The nature of warfare has always been largely determined by contemporary technology. Instances of technological change undertaken for the sake of military advantage have also been relatively common in history. The relationships between science and warfare, however, have been much more variable and ambiguous. The papers and discussions of the Symposium investigate selected aspects of the complex relationships between science and technology on the one hand, and warfare on the other, from the Renaissance to the 1960s. In the first session, Professor Hall takes up in turn the possible areas of interaction between science (exterior ballistics, engineering, explosives, mechanics, and metallurgy) and military technology (edge weapons, cannons and mortars, fortification and siege warfare, and small arms) in the 15th, 16th, and 17th centuries. The notion that science is pursued for utilitarian ends, Hall finds, is an unhistorical projection backward from our own age." He excludes navigation and medicine from consideration, because they were civil as well as military concerns. In spite of the pleading of certain early propagandists of the Empire of Man over Nature," and in spite of the elaborate sketches of military engines in Leonardo's notebooks, military technology was largely innocent of scientific method. The developments in fortification required mathematical skills, but nothing more than elementary geometry and arithmetic. Mathematicians studied the ancient problem of the trajectory of projectiles, but their efforts affected neither the design nor the use of guns. The range tables they provided were not even usable with the guns of the time. The solution of the trajectory problem would await Benjamin Robins and the 18th century. Professor Hale supports Hall's conclusion with three arguments. In the 16th and 17th centuries, armies were so organized as to preclude any productive contact with the worlds of science and technology.
