Book Description
Harmonic distortion problems include equipment overheating, motor failures, capacitor failure and inaccurate power metering. The topic of power system harmonics was covered for the first time 20 years ago and the first edition has become a standard reference work in this area. Unprecedented developments in power electronic devices and their integration at all levels in the power system require a new look at the causes and effects of these problems, and the state of hardware and software available for harmonic assessment. Following the successful first edition, this second edition of Power System Harmonics maintains the practical approach to the subject and discusses the impact of advanced power electronic technology on instrumentation, simulation, standards and active harmonic elimination techniques. Features include: A new chapter on modern digital instrumentation techniques. Added sections on active filters and modern distorting devices such as FACTS devices, multilevel conversion, current source, voltage source inverters and turn-OFF-related power electronic devices. References to international standards for harmonics and inter-harmonics. Numerical examples of technique application. Offering a comprehensive understanding of power systems, this book is an asset to power engineers involved in the planning, design and operation of power system generation, transmission and distribution. Researchers and postgraduate students in the field will also benefit from this useful reference.

Book Description
Sixteen-year-old, music- and sound design-obsessed Drea doesn't have friends. She has, as she's often reminded, issues. Drea's mom and a rotating band of psychiatrists have settled on "a touch of Asperger's." Having just moved to the latest in a string of new towns, Drea meets two other outsiders. And Naomi and Justin seem to actually like Drea. The three of them form a band after an impromptu, Portishead-comparison-worthy jam after school. Justin swiftly challenges not only Drea's preference for Poe over Black Lab but also her perceived inability to connect with another person. Justin, against all odds, may even like like Drea. It's obvious that Drea can't hide behind her sound equipment anymore. But just when she's found not one but two true friends, can she stand to lose one of them? Harmonic Feedback is a 2011 Bank Street - Best Children's Book of the Year.

Book Description
Modular forms and Jacobi forms play a central role in many areas of mathematics. Over the last 10–15 years, this theory has been extended to certain non-holomorphic functions, the so-called “harmonic Maass forms”. The first glimpses of this theory appeared in Ramanujan's enigmatic last letter to G. H. Hardy written from his deathbed. Ramanujan discovered functions he called “mock theta functions” which over eighty years later were recognized as pieces of harmonic Maass forms. This book contains the essential features of the theory of harmonic Maass forms and mock modular forms, together with a wide variety of applications to algebraic number theory, combinatorics, elliptic curves, mathematical physics, quantum modular forms, and representation theory.

Book Description
An exploration of musical harmony from its ancient fundamentals to its most complex modern progressions, addressing how and why it resonates emotionally and spiritually in the individual. W. A. Mathieu, an accomplished author and recording artist, presents a way of learning music that reconnects modern-day musicians with the source from which music was originally generated. As the author states, "The rules of music--including counterpoint and harmony--were not formed in our brains but in the resonance chambers of our bodies." His theory of music reconciles the ancient harmonic system of just intonation with the modern system of twelve-tone temperament. Saying that the way we think music is far from the way we do music, Mathieu explains why certain combinations of sounds are experienced by the listener as harmonious. His prose often resembles the rhythms and cadences of music itself, and his many musical examples allow readers to discover their own musical responses.

Book Description
Harmonics, Power Systems, and Smart Grids, Second Edition compiles the most relevant aspects of harmonics in a way that the unfamiliar reader can better grasp the subject matter and the experienced reader can directly access specific subjects of interest. The text begins with a definition of harmonics, along with analytical expressions for electrical parameters under nonsinusoidal situations, and then: Discusses important and widely used industry standards to control harmonic distortion levels Describes methods to mitigate the effects of harmonics, detailing the operation principles and design of passive filters and active filter fundamentals Presents alternative methods, such as stiffer AC sources, power converters with increased number of pulses, series reactors, and load reconfiguration Reviews the elements that play a role in the study of the propagation of harmonic currents in a distribution network Explains how to determine power losses in electrical equipment attributed to harmonic waveform distortion Covers harmonics from solar and wind power converters and power electronics in FACTS and HVDC technologies Explores harmonics from electric vehicles connected to the grid, superconductive fault current limiters, and electric vehicle charging stations Featuring three new chapters, a number of new examples and figures, and updates throughout, Harmonics, Power Systems, and Smart Grids, Second Edition provides a comprehensive reference on harmonic current generation, propagation, and control in electrical power networks, including the broadly cited smart grid.

Book Description
Aiming at a better understanding of power system harmonics, this text presents a discussion of this issue, providing a quantitative analysis when possible. Pertinent equations are developed. 80 practical case studies based on real-life work experience come with the text. These are analysed providing the results and commenting on the output. Furthermore, 80 end-of-chapter problems are provided. A detailed solution manual is available. The book can be used as a textbook for undergraduate and graduate students, in short-courses offered by consultants and institutes, as well as a tutorial, reference, or self-study course for practising engineers in the industry and electric utility.
