Three-phase AC-AC Power Converters Based on Matrix Converter Topology

by Paweł Szcześniak

AC voltage frequency changes is one of the most important functions of solid state power converters. The most desirable features in frequency converters are the ability to generate load voltages with arbitrary amplitude and frequency, sinusoidal currents and voltages waveforms; the possibility of providing unity power factor for any load; and, finally, a simple and compact power circuit. Over the past decades, a number of different frequency converter topologies have appeared in the literature, but only the converters with either a voltage or current DC link are commonly used in industrial applications. Improvements in power semiconductor switches over recent years have resulted in the development of many structures of AC-AC converters without DC electric energy storage. Such converters are an alternative solution for frequently recommended systems with DC energy storage and are characterized by a lower price, smaller size and longer lifetime. Most of the these topologies are based on the structure of the matrix converter. Three-Phase AC-AC Power Converters Based On Matrix Converter Topology: Matrix-reactance frequency converters concept presents a review of power frequency converters, with special attention paid to converters without DC energy storage. Particular attention is paid to nine new converters named matrix-reactance frequency converters which have been developed by the author and the team of researchers from Institute of Electrical Engineering at the University of Zielona Góra. The topologies of the presented matrix-reactance frequency converters are based on a three-phase unipolar buck-boost matrix-reactance chopper with source or load switches arranged as in a matrix converter. This kind of approach makes it possible to obtain an output voltage greater than the input one (similar to that in a matrix-reactance chopper) and a frequency conversion (similar to that in a matrix converter). Written for researchers and Ph.D. students working in the field of power electronics converters and drive systems, Three-Phase AC-AC Power Converters Based On Matrix Converter Topology: Matrix-reactance frequency converters concept will also be valuable to power electronics converter designers and users; R&D centers; and readers needing industry solutions in variable speed drive systems, such as automation and aviation.

Threshold: Emergency Responders On The U.S. - Mexico Border

by Ieva Jusionyte

Emergency responders on the US-Mexico border operate at the edges of two states. They rush patients to hospitals across country lines, tend to the broken bones of migrants who jump over the wall, and put out fires that know no national boundaries. Paramedics and firefighters on both sides of the border are tasked with saving lives and preventing disasters in the harsh terrain at the center of divisive national debates. <P><P> Ieva Jusionyte’s firsthand experience as an emergency responder provides the background for her gripping examination of the politics of injury and rescue in the militarized region surrounding the US-Mexico border. Operating in this area, firefighters and paramedics are torn between their mandate as frontline state actors and their responsibility as professional rescuers, between the limits of law and pull of ethics. From this vantage they witness what unfolds when territorial sovereignty, tactical infrastructure, and the natural environment collide. Jusionyte reveals the binational brotherhood that forms in this crucible to stand in the way of catastrophe. Through beautiful ethnography and a uniquely personal perspective, Threshold provides a new way to understand politicized issues ranging from border security and undocumented migration to public access to healthcare today.

Through Optimization of Aerospace Vehicle Trajectories by the Pontryagin Maximum Principle (Studies in Systems, Decision and Control #579)

by Alexander S. Filatyev Vyacheslav G. Petukhov

This monograph investigates the trajectory optimization problems of low- and finite-thrust aerospace vehicles and spacecraft using an indirect method based on the Pontryagin maximum principle, providing a methodological basis for the construction of numerical techniques that are superior in versatility and accuracy to direct methods. This book provides a theoretical explanation of the approaches used and also an extensive gallery of the results of practical numerical studies. The problem of boundary value problem convergence has been largely overcome, which has made it possible to practically automate the optimization of trajectories and to achieve a qualitative generalization with a number of fundamentally new results. Examples of practical optimization of branching trajectories of complex dynamics systems with finite and continual sets of branches, in deterministic and stochastic statements, with control constraints and phase constraints of various orders are demonstrated. An emphasis is placed on the consistent application of methods of numerical continuation with respect to a parameter to solve various problems in the flight mechanics of spacecraft with an electric propulsion system (EPS). The problems considered include the optimization of direct interplanetary flights of spacecraft with thrusters having limited power or limited thrust, of interplanetary flights of such spacecraft using gravity assisted maneuvers, of multi-orbit interorbital transfers of spacecraft with limited-thrust EPS. As a result, it was possible to develop a set of numerical continuation methods for solving a wide range of optimization problems for spacecraft trajectories with EPS with improved characteristics in terms of convergence and performance. This monograph also contains a description of many pitfalls in solving a wide range of problems of optimizing the trajectories of aerospace vehicles and recipes for effectively overcoming them.

Through the Glass Ceiling to the Stars: The Story of the First American Woman to Command a Space Mission

by Jonathan H. Ward Col. Eileen M. Collins Usaf

The long-awaited memoir of a trailblazer and role model who is telling her story for the first time. <p><p> Eileen Collins was an aviation pioneer her entire career, from her crowning achievements as the first woman to command an American space mission as well as the first to pilot the space shuttle to her early years as one of the Air Force's first female pilots. She was in the first class of women to earn pilot's wings at Vance Air Force Base and was their first female instructor pilot. She was only the second woman pilot admitted to the Air Force's elite Test Pilot Program at Edwards Air Force Base. NASA had such confidence in her skills as a leader and pilot that she was entrusted to command the first shuttle mission after the Columbia disaster, returning the US to spaceflight after a two-year hiatus. Since retiring from the Air Force and NASA, she has served on numerous corporate boards and is an inspirational speaker about space exploration and leadership. <p><p> Eileen Collins is among the most recognized and admired women in the world, yet this is the first time she has told her story in a book. It is a story not only of achievement and overcoming obstacles but of profound personal transformation. The shy, quiet child of an alcoholic father and struggling single mother, who grew up in modest circumstances and was an unremarkable student, she had few prospects when she graduated from high school, but she changed her life to pursue her secret dream of becoming an astronaut. She shares her leadership and life lessons throughout the book with the aim of inspiring and passing on her legacy to a new generation.

Through-the-Wall Radar Imaging

by Moeness G. Amin

Through-the-wall radar imaging (TWRI) allows police, fire and rescue personnel, first responders, and defense forces to detect, identify, classify, and track the whereabouts of humans and moving objects. Electromagnetic waves are considered the most effective at achieving this objective, yet advances in this multi-faceted and multi-disciplinary technology require taking phenomenological issues into consideration and must be based on a solid understanding of the intricacies of EM wave interactions with interior and exterior objects and structures. Providing a broad overview of the myriad factors involved, namely size, weight, mobility, acquisition time, aperture distribution, power, bandwidth, standoff distance, and, most importantly, reliable performance and delivery of accurate information, Through-the-Wall Radar Imaging examines this technology from the algorithmic, modeling, experimentation, and system design perspectives. It begins with coverage of the electromagnetic properties of walls and building materials, and discusses techniques in the design of antenna elements and array configurations, beamforming concepts and issues, and the use of antenna array with collocated and distributed apertures. Detailed chapters discuss several suitable waveforms inverse scattering approaches and revolve around the relevance of physical-based model approaches in TWRI along with theoretical and experimental research in 3D building tomography using microwave remote sensing, high-frequency asymptotic modeling methods, synthetic aperture radar (SAR) techniques, impulse radars, airborne radar imaging of multi-floor buildings strategies for target detection, and detection of concealed targets. The book concludes with a discussion of how the Doppler principle can be used to measure motion at a very fine level of detail. The book provides a deep understanding of the challenges of TWRI, stressing its multidisciplinary and phenomenological nature. The breadth and depth of topics covered presents a highly detailed treatment of this potentially life-saving technology.

Throwing Rocks at the Google Bus

by Douglas Rushkoff

Why doesn't the explosive growth of companies like Facebook and Uber deliver more prosperity for everyone? What is the systemic problem that sets the rich against the poor and the technologists against everybody else? When protesters shattered the windows of a bus carrying Google employees to work, their anger may have been justifiable, but it was misdirected. The true conflict of our age isn't between the unem­ployed and the digital elite, or even the 99 percent and the 1 percent. Rather, a tornado of technological improvements has spun our economic program out of control, and humanity as a whole--the pro-testers and the Google employees as well as the shareholders and the executives--are all trapped by the consequences. It's time to optimize our economy for the human beings it's supposed to be serving. In this groundbreaking book, acclaimed media scholar and author Douglas Rushkoff tells us how to combine the best of human nature with the best of modern technology. Tying together disparate threads--big data, the rise of robots and AI, the increasing participation of algorithms in stock market trading, the gig economy, the collapse of the eurozone--Rushkoff provides a critical vocabulary for our economic moment and a nuanced portrait of humans and commerce at a critical crossroads.From the Hardcover edition.

Thunderstruck

by Erik Larson

A true story of love, murder, and the end of the world&’s &“great hush.&”In Thunderstruck, Erik Larson tells the interwoven stories of two men—Hawley Crippen, a very unlikely murderer, and Guglielmo Marconi, the obsessive creator of a seemingly supernatural means of communication—whose lives intersect during one of the greatest criminal chases of all time.Set in Edwardian London and on the stormy coasts of Cornwall, Cape Cod, and Nova Scotia, Thunderstruck evokes the dynamism of those years when great shipping companies competed to build the biggest, fastest ocean liners; scientific advances dazzled the public with visions of a world transformed; and the rich outdid one another with ostentatious displays of wealth. Against this background, Marconi races against incredible odds and relentless skepticism to perfect his invention: the wireless, a prime catalyst for the emergence of the world we know today. Meanwhile, Crippen, &“the kindest of men,&” nearly commits the perfect murder.With his unparalleled narrative skills, Erik Larson guides us through a relentlessly suspenseful chase over the waters of the North Atlantic. Along the way, he tells of a sad and tragic love affair that was described on the front pages of newspapers around the world, a chief inspector who found himself strangely sympathetic to the killer and his lover, and a driven and compelling inventor who transformed the way we communicate.

Thyroid Systems Engineering: A Primer in Mathematical Modeling of the Hypothalamus-Pituitary-Thyroid Axis

by Simon Goede Melvin Khee-Shing Leow

In recent years, a considerable amount of effort has been devoted, both in industry and academia, towards the behavioral modeling, evaluation and prediction of the hypothalamus pituitary thyroid system.Thyroid Systems Engineering targets an optimal treatment of people suffering from thyroid hormone disorders. The content is motivated by in-depth observations of such patients whose rich data supported the theoretical framework arising from formal mathematical reasoning, guided by the nature of thyroid physiology. Leveraging on the insights emerging from the unique combination of an electrical engineer working with a clinical thyroidologist, and both being scientists skilled in mathematics, the authors introduce this new discipline and field of scientific investigation aptly designated as Thyroid Systems Engineering.Readers will discover that mathematics can indeed model the behavior of the hypothalamus-pituitary-thyroid (HPT) axis. Focused on modeling, each of the eighteen chapters gives the reader a notion of the application of relevant mathematics to pertinent issues encountered in mainstream thyroidology. Many cellular processes resemble the flux of variables and states in a complex multi-parameter space through time analogous to current flow in electrical networks. It is then logical to apply the principles and physical laws of electrodynamics, electrical network theory, control systems theory and signal theory to many of the biological phenomena encountered in endocrinology. Such an approach is used liberally throughout the book and successfully yields elegant solutions to a number of models presented within.This book can serve as a reference to mathematical modeling in other aspects of endocrine physiology, and as the starting point for a fundamental course in medical modeling. It will appeal to postgraduates in electrical engineering, academic physicians and biomedical researchers. Further, readers equipped with advanced calculus, electrical network theory, control theory and signal theory should be able to follow the mathematical expositions that describe thyrotropic control. They represent a new discipline based on mathematical modeling in physiology applicable to medical diagnostics, measurement and treatment to cooperate in the clinical team and realize an optimized treatment for patients.

Thysanoptera: An Identification Guide, 2nd Edition

by Laurence Mound Geoffrey Kibby

A number of species of Thysanoptera (thrips) are increasingly important crop pests in many parts of the world, as well as in some cases being vectors of plant disease. Communicating the known information about a species of organism is dependent on our ability to recognise or identify it accurately. This book is a completely revised and rewritten edition of the standard, widely used manual on these minute flying insects written by J M Palmer, L A Mound and G J du Heaume and published in 1989 as CIE Guides to Insects of Importance to Man 2. Thysanoptera, which provides a practical identification guide on a worldwide scale. The previous version posed problems for students in terms of fluency in English & knowledge of dichotomous keys. However, this thoroughly updated edition incorporates a new set of pictorial keys, which have been developed and used very successfully for training courses at the International Institute of Entomology and which will greatly enhance the ability of the non-specialist to identify thrips to species. Individuals of these insects can usually be identified only by examination under a microscope, often at high power. Within each species, individuals can vary in size, colour and shape and their appearance can be altered by techniques used in preparation. This booklet describes techniques used in the preparation of thrip specimens onto slides for identification and the means of identifying slide-mounted specimens most commonly encountered. It also introduces students to the biological diversity that is found amongst the Thysanoptera, their economic importance in terms of both damaging and beneficial effects, new identification techniques, additional information and taxa, glossary of technical terms, notes on each genus (described alphabetically within their families and subfamilies). Supplementary keys to species are also given within four genera that include several pest species (Caliothrips, Frankliniella, Scirtothrips and Thrips) along with new distribution records which have occurred since the publication of the first edition. It is an essential tool for applied entomologists and crop protection specialists involved in the control of crop pest thrips, and thrip taxonomists.

Ticker: The Quest to Create an Artificial Heart

by Mimi Swartz

It wasn’t supposed to be this hard. If America could send a man to the moon, shouldn’t the best surgeons in the world be able to build an artificial heart? In Ticker, Texas Monthly executive editor and two time National Magazine Award winner Mimi Swartz shows just how complex and difficult it can be to replicate one of nature’s greatest creations. Part investigative journalism, part medical mystery, Ticker is a dazzling story of modern innovation, recounting fifty years of false starts, abysmal failures and miraculous triumphs, as experienced by one the world’s foremost heart surgeons, O.H. “Bud” Frazier, who has given his life to saving the un-savable. His journey takes him from a small town in west Texas to one of the country’s most prestigious medical institutions, The Texas Heart Institute, from the halls of Congress to the animal laboratories where calves are fitted with new heart designs. The roadblocks to success —medical setbacks, technological shortcomings, government regulations – are immense. Still, Bud and his associates persist, finding inspiration in the unlikeliest of places. A field beside the Nile irrigated by an Archimedes screw. A hardware store in Brisbane, Australia. A seedy bar on the wrong side of Houston. Until post WWII, heart surgery did not exist. Ticker provides a riveting history of the pioneers who gave their all to the courageous process of cutting into the only organ humans cannot live without. Heart surgeons Michael DeBakey and Denton Cooley, whose feud dominated the dramatic beginnings of heart surgery. Christian Barnaard, who changed the world overnight by performing the first heart transplant. Inventor Robert Jarvik, whose artificial heart made patient Barney Clark a worldwide symbol of both the brilliant promise of technology and the devastating evils of experimentation run amuck. Rich in supporting players, Ticker introduces us to Bud’s brilliant colleagues in his quixotic quest to develop an artificial heart: Billy Cohn, the heart surgeon and inventor who devotes his spare time to the pursuit of magic and music; Daniel Timms, the Brisbane biomedical engineer whose design of a lightweight, pulseless heart with but a single moving part offers a new way forward. And, as government money dries up, the unlikeliest of backers, Houston’s furniture king, Mattress Mack. In a sweeping narrative of one man’s obsession, Swartz raises some of the hardest questions of the human condition. What are the tradeoffs of medical progress? What is the cost, in suffering and resources, of offering patients a few more months, or years of life? Must science do harm to do good? Ticker takes us on an unforgettable journey into the power and mystery of the human heart.
