Download or read book Electrical Machines and Drives written by Jan A. Melkebeek and published by Springer. This book was released on 2018-01-20 with total page 740 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book aims to offer a thorough study and reference textbook on electrical machines and drives. The basic idea is to start from the pure electromagnetic principles to derive the equivalent circuits and steady-state equations of the most common electrical machines (in the first parts). Although the book mainly concentrates on rotating field machines, the first two chapters are devoted to transformers and DC commutator machines. The chapter on transformers is included as an introduction to induction and synchronous machines, their electromagnetics and equivalent circuits. Chapters three and four offer an in-depth study of induction and synchronous machines, respectively. Starting from their electromagnetics, steady-state equations and equivalent circuits are derived, from which their basic properties can be deduced. The second part discusses the main power-electronic supplies for electrical drives, for example rectifiers, choppers, cycloconverters and inverters. Much attention is paid to PWM techniques for inverters and the resulting harmonic content in the output waveform. In the third part, electrical drives are discussed, combining the traditional (rotating field and DC commutator) electrical machines treated in the first part and the power electronics of part two. Field orientation of induction and synchronous machines are discussed in detail, as well as direct torque control. In addition, also switched reluctance machines and stepping motors are discussed in the last chapters. Finally, part 4 is devoted to the dynamics of traditional electrical machines. Also for the dynamics of induction and synchronous machine drives, the electromagnetics are used as the starting point to derive the dynamic models. Throughout part 4, much attention is paid to the derivation of analytical models. But, of course, the basic dynamic properties and probable causes of instability of induction and synchronous machine drives are discussed in detail as well, with the derived models for stability in the small as starting point. In addition to the study of the stability in the small, a chapter is devoted to large-scale dynamics as well (e.g. sudden short-circuit of synchronous machines). The textbook is used as the course text for the Bachelor’s and Master’s programme in electrical and mechanical engineering at the Faculty of Engineering and Architecture of Ghent University. Parts 1 and 2 are taught in the basic course ’Fundamentals of Electric Drives’ in the third bachelor. Part 3 is used for the course ’Controlled Electrical Drives’ in the first master, while Part 4 is used in the specialised master on electrical energy.

Download or read book Dynamic Modelling written by Alisson Brito and published by BoD – Books on Demand. This book was released on 2010-01-01 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: When talking about modelling it is natural to talk about simulation. Simulation is the imitation of the operation of a real-world process or systems over time. The objective is to generate a history of the model and the observation of that history helps us understand how the real-world system works, not necessarily involving the real-world into this process. A system (or process) model takes the form of a set of assumptions concerning its operation. In a model mathematical and logical assumptions are considered, and entities and their relationship are delimited. The objective of a model – and its respective simulation – is to answer a vast number of “what-if” questions. Some questions answered in this book are: What if the power distribution system does not work as expected? What if the produced ships were not able to transport all the demanded containers through the Yangtze River in China? And, what if an installed wind farm does not produce the expected amount of energyt? Answering these questions without a dynamic simulation model could be extremely expensive or even impossible in some cases and this book aims to present possible solutions to these problems.
Download or read book Operational Amplifiers written by Johan Huijsing and published by Springer Science & Business Media. This book was released on 2011-04-23 with total page 430 pages. Available in PDF, EPUB and Kindle. Book excerpt: Operational Amplifiers – Theory and Design, Second Edition presents a systematic circuit design of operational amplifiers. Containing state-of-the-art material as well as the essentials, the book is written to appeal to both the circuit designer and the system designer. It is shown that the topology of all operational amplifiers can be divided into nine main overall configurations. These configurations range from one gain stage up to four or more stages. Many famous designs are evaluated in depth. Additional chapters included are on systematic design of μV-offset operational amplifiers and precision instrumentation amplifiers by applying chopping, auto-zeroing, and dynamic element-matching techniques. Also, techniques for frequency compensation of amplifiers with high capacitive loads have been added. Operational Amplifiers – Theory and Design, Second Edition presents high-frequency compensation techniques to HF-stabilize all nine configurations. Special emphasis is placed on low-power low-voltage architectures with rail-to-rail input and output ranges. In addition to presenting characterization of operational amplifiers by macro models and error matrices, together with measurement techniques for their parameters it also develops the design of fully differential operational amplifiers and operational floating amplifiers. Operational Amplifiers – Theory and Design, Second Edition is carefully structured and enriched by numerous figures, problems and simulation exercises and is ideal for the purpose of self-study and self-evaluation.

Book excerpt: The outside world was misled to believe that all 550 people inside the hospital had been evacuated. No one knew they were there. They could hear the helicopters flying overhead and see the rescue attempts nearby at the Superdome. They shined flashlights out the window at night with the hope that someone would see them. Thirty-something people would gather and hold hands in prayer with the hope of even a word of rescue. They waited and waited. But no one came. They were cut off from the outside world-completely "Disconnected."
Download or read book Low Level Hell written by Hugh L. Mills, Jr. and published by Presidio Press. This book was released on 2009-01-16 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aeroscouts of the 1st Infantry Division had three words emblazoned on their unit patch: Low Level Hell. It was then and continues today as the perfect concise definition of what these intrepid aviators experienced as they ranged the skies of Vietnam from the Cambodian border to the Iron Triangle. The Outcasts, as they were known, flew low and slow, aerial eyes of the division in search of the enemy. Too often for longevity’s sake they found the Viet Cong and the fight was on. These young pilots (19-22 years old) “invented” the book as they went along. Praise for Low Level Hell “An absolutely splendid and engrossing book. The most compelling part is the accounts of his many air-to-ground engagements. There were moments when I literally held my breath.”—Dr. Charles H. Cureton, Chief Historian, U.S. Army Training and Doctrine (TRADOC) Command “Low Level Hell is the best ‘bird’s eye view’ of the helicopter war in Vietnam in print today. No volume better describes the feelings from the cockpit. Mills has captured the realities of a select group of aviators who shot craps with death on every mission.”—R.S. Maxham, Director, U.S. Army Aviation Museum

A cannon. A strap. A piece. A biscuit. A burner. A heater. A chopper. A gat. A hammer A tool for RULE Or, you can call it a gun. That’s what fifteen-year-old Will has shoved in the back waistband of his jeans. See, his brother Shawn was just murdered. And Will knows the rules. No crying. No snitching. Revenge. That’s where Will’s now heading, with that gun shoved in the back waistband of his jeans, the gun that was his brother’s gun. He gets on the elevator, seventh floor, stoked. He knows who he’s after. Or does he? As the elevator stops on the sixth floor, on comes Buck. Buck, Will finds out, is who gave Shawn the gun before Will took the gun. Buck tells Will to check that the gun is even loaded. And that’s when Will sees that one bullet is missing. And the only one who could have fired Shawn’s gun was Shawn. Huh. Will didn’t know that Shawn had ever actually USED his gun. Bigger huh. BUCK IS DEAD. But Buck’s in the elevator? Just as Will’s trying to think this through, the door to the next floor opens. A teenage girl gets on, waves away the smoke from Dead Buck’s cigarette. Will doesn’t know her, but she knew him. Knew. When they were eight. And stray bullets had cut through the playground, and Will had tried to cover her, but she was hit anyway, and so what she wants to know, on that fifth floor elevator stop, is, what if Will, Will with the gun shoved in the back waistband of his jeans, MISSES. And so it goes, the whole long way down, as the elevator stops on each floor, and at each stop someone connected to his brother gets on to give Will a piece to a bigger story than the one he thinks he knows. A story that might never know an END…if Will gets off that elevator. Told in short, fierce staccato narrative verse, Long Way Down is a fast and furious, dazzlingly brilliant look at teenage gun violence, as could only be told by Jason Reynolds.
Download or read book Leading from Behind written by Richard Miniter and published by St. Martin's Press. This book was released on 2012-08-21 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: Barack Obama has never been fully vetted—until now. In the New York Times bestselling Leading from Behind, investigative journalist Richard Miniter presents the first book to explore President Obama's abilities as a leader, by unearthing new details of his biggest successes and failures. Based on exclusive interviews and never-before-published material, Leading from Behind investigates the secret world of the West Wing and the combative personalities that shape historic events. Contrary to the White House narrative, which aims to define Obama as a visionary leader, Leading from Behind reveals a president who is indecisive, moody, and often paralyzed by competing political considerations. Many victories—as well as several significant failures—during the Obama presidency are revealed to be the work of strong women, who led when the president did not: then-Speaker Nancy Pelosi; Secretary of State Hillary Clinton; and Valerie Jarrett, his closest adviser and an Obama family confidante, whose unusual degree of influence has been a source of conflict with veteran political insiders. In Leading from Behind, you will learn: · Why Obama's relationship with Israel was poisoned years before he met Israel's prime minister Benjamin Netanyahu · The real reason for Valerie Jarrett's strong hold over both Barack and Michelle Obama · ObamaCare wasn't Obama's idea. It was House Speaker Nancy Pelosi's. And the real reason he danced to her tune. · Obama delayed and canceled the mission to kill Osama bin Laden three times and then committed an intelligence blunder that allowed dozens of high-level members of al Qaeda to escape. · Why Obama destroyed a secret budget deal with House Speaker John Boehner that would have reformed entitlements, slashed spending, and reduced the national debt—without raising taxes · Why Obama is determined to save Attorney General Eric Holder, even though he has mislead and stonewalled Congress about "Operation: Fast and Furious" · Why Obama decided to defy the Tea Party and ditch his plans to end earmarks In Leading from Behind, Richard Miniter's provocative research offers a dramatic, thoroughly sourced account of President Obama's White House during a time of intense domestic controversy and international turmoil.
