Reflecting the increasing demand for efficient conversion and control of electrical power, it considers the latest power devices, circuits, and control schemes that continue to extend power electronics technology to new applications areas. Presents material methodically - first establishing the background theory before going on to specific applications. Familiarizes readers with the analysis and operation of various power conversions circuits that have applications at high power levels, and formulates equations that govern the behavior of these circuits. Discusses the application of power electronic devices in uncontrolled and controlled single phase rectifiers, inverters, ac voltage controllers, cycloconverters, and dc choppers, and demonstrates voltage and current waveform analysis for the output, starting with a simple resistive load to more practical inductive loads. Includes many worked examples, basic formulas, and an abundance of illustrations and diagrams.

    Their lives are hard—regulated by the seasons and by the ceaseless annual labours of hoeing and digging, planting and harvesting. But it is also a life of peace, lived in a well-knit community of wise elders and caring—though sometimes overbearing—neighbours and relatives. This peace is shattered when Kevi, a young hunter, lithe and possessed of an animal magnetism, better looking than any other man in the village, comes to them at harvest time offering help and a hunk of venison. Kevi falls in love with Atuonuo and proposes marriage. Atuonuo, young in years and unsure of her heart, turns him down. But love becomes menacing when Kevi, angered by the rejection, viciously turns on Atuonuo, and reveals a side of himself that neither mother nor daughter could have imagined in their worst nightmares.With grace and in restrained, lyrical prose, Easterine Kire draws upon legend and a profound understanding of human nature to weave a compelling tale of love and the demons it sometimes conjures.

    The Chapters in the book deal with thermodynamic concepts such as the P-V-T behaviour of fluids, the phase behaviour of pure materials and solutions. It also explains the concepts such as density, heat capacity, latent heat, heat of reaction, calorific values, vapour pressure, humidity, etc. This book is intended as a textbook for undergraduate courses in chemical engineering and related disciplines such as biotechnology, polymer technology, petrochemical engineering, electrochemical engineering, environmental engineering, safety engineering and industrial chemistry.

    

    Now The BLDGBLOG Book distills author Geoff Manaugh's unique vision, offering an enthusiastic, idea-filled guide to the future of architecture, with stunning images and exclusive new content. From underground exploration to the novels of J.G. Ballard, from artificial glaciers in the mountains of Pakistan to weather control in Olympic Beijing, The BLDGBLOG Book is "part conceptual travelogue, part manifesto, part sci-fi novel," according to Joseph Grima, executive director of New York's Storefront for Art and Architecture."BLDGBLOG is something new and substantially different from anything else I have seen," says Errol Morris, Director of Fast, Cheap & Out of Control and the Academy Award-winning documentary Fog of War. "Secretly, I had always hoped it would become a book. Geoff Manaugh has provided the reader with an excursion into a new world—part digital fantasy, part reality at the intersection of art, architecture, landscape design, and pure ideas. Like the blog, the book is personal, idiosyncratic, and, best of all, incredibly interesting."

    The consequences of this gathering may be enormous. In this new ebook, experts Patrick J. Michaels and Paul C. Knappenberger assess the issues sure to drive the debate before, during, and after the Paris meeting.

    The calls to ban it were more or less instant.Re:cyclists is the tale of what happened next, of how we have spent two centuries wheeling our way about town and country on bikes--or on two-wheeled things that vaguely resembled what we now call bikes. Michael Hutchinson picks his way through those 200 years, discovering how cycling became a kinky vaudeville act for Parisians, how it became an American business empire, and how it went on to find a unique home in the British Isles. He considers the penny-farthing riders exploring the abandoned and lonely coaching roads during the railway era, and the Victorian high-society cyclists of the 1890s bicycle craze--a time when no aristocratic house party was without bicycles and when the Prince of Wales used to give himself an illicit thrill on a weekday afternoon by watching the women's riding-school in the Royal Albert Hall.Re:cyclists looks at how cycling became the sport, the pastime and the social life of millions of ordinary people, how it grew and how it suffered through the 1960s and '70s, and how at the dawn of the twenty-first century it rose again, much changed but still ultimately just someone careering along on two wheels.

    During the lend-lease agreement with the USA, the RAF and Fleet Air Arm operated several American designs, each of which was tested to evaluate its potential.This book looks at the key area of fighter aircraft and includes the test results and pilot's own first-hand accounts of flying seventeen different models, designed in the UK, America and Germany. The reader will learn of the possibilities of air superiority offered by these types and also their weaknesses. Types included are The Hawker Hurricane, Supermarine Spitfire, Boulton Paul Defiant, Hawker Tempest and Typhoon, Bell Airacobra, Messerschmitt Bf 109, Focke-Wulf Fw 190, Brewster Buffalo, Curtiss Tomahawk, North American Mustang, Grumman Martlet, Republic Thunderbolt, and Vought Corsair. All aircraft that saw a great deal of action throughout the War and which are now part of legend.

    Groundbreaking in every way when first published, this book is a simple, straightforward, direct calculus text. It's popularity is directly due to its broad use of applications, the easy-to-understand writing style, and the wealth of examples and exercises which reinforce conceptualization of the subject matter. The author wrote this text with three objectives in mind. The first was to make the book more student-oriented by expanding discussions and providing more examples and figures to help clarify concepts. To further aid students, guidelines for solving problems were added in many sections of the text. The second objective was to stress the usefulness of calculus by means of modern applications of derivatives and integrals. The third objective, to make the text as accurate and error-free as possible, was accomplished by a careful examination of the exposition, combined with a thorough checking of each example and exercise.

    • Mercury thermometers are prohibited on airplanes for a crucial reason.• Kryptonite bicycle locks are easily broken.“Things fall apart” is more than a poetic insight—it is a fundamental property of the physical world. Why Things Break explores the fascinating question of what holds things together (for a while), what breaks them apart, and why the answers have a direct bearing on our everyday lives.When Mark Eberhart was growing up in the 1960s, he learned that splitting an atom leads to a terrible explosion—which prompted him to worry that when he cut into a stick of butter, he would inadvertently unleash a nuclear cataclysm. Years later, as a chemistry professor, he remembered this childhood fear when he began to ponder the fact that we know more about how to split an atom than we do about how a pane of glass breaks.In Why Things Break, Eberhart leads us on a remarkable and entertaining exploration of all the cracks, clefts, fissures, and faults examined in the field of materials science and the many astonishing discoveries that have been made about everything from the explosion of the space shuttle Challenger to the crashing of your hard drive. Understanding why things break is crucial to modern life on every level, from personal safety to macroeconomics, but as Eberhart reveals here, it is also an area of cutting-edge science that is as provocative as it is illuminating.“An engaging personal account not just of the physics and chemistry of materials but of the ethics, economics, and politics of innovation, with delightful bonuses on topics from the origins of ‘ghostly’ noises in old houses to the amazing coevolution of armor and armor-piercing projectiles. If it ain’t broke, Mark Eberhart can tell you why—and explain equally well why a shatterproof world remains beyond our reach.”—Edward Tenner, author of Our Own Devices and Why Things Bite Back“I don’t remember a book that has taught me so much, nor previously encountering a teacher like the marvelous Mark Eberhart, who in Why Things Break provides enlightening and thoroughly captivating scientific explanations of subjects ranging from the structural failures leading to the sinking of the Titanic to everyday, no-less-fascinating topics such as the reason why, even at the same temperature, winter days always seem so much colder in Boston than in Denver.”—Richard Restak, M.D., author of Mozart’s Brain and The Fighter Pilot“Eberhart brings his insights to the reader by weaving personal anecdotes—from his childhood fear that cutting a stick of butter would release the energy of the atoms within to his arrival in Boston for an interview with MIT without a suitable winter coat—into a fascinating discussion of the forces that hold atoms and molecules together. A lively, unvarnished look at chemistry on the cutting edge.” —Kirkus Reviews

    These "cowboys of the skies," as one journalist called them, were the structural ironworkers who walked steel beams -- no wider, often, than the face of a hardcover book -- hundreds of feet above ground, to raise the soaring towers and vaulting bridges that so abruptly transformed America in the twentieth century.Many early ironworkers were former sailors, new Americans of Irish and Scandinavian descent accustomed to climbing tall ships' masts and schooled in the arts of rigging. Others came from a small Mohawk Indian reservation on the banks of the St. Lawrence River or from a constellation of seaside towns in Newfoundland. What all had in common were fortitude, courage, and a short life expectancy. "We do not die," went an early ironworkers' motto. "We are killed."High Steel is the stirring epic of these men and of the icons they built -- and are building still. Shifting between past and present, Jim Rasenberger travels back to the earliest iron bridges and buildings of the nineteenth century; to the triumph of the Brooklyn Bridge and the 1907 tragedy of the Quebec Bridge, where seventy-five ironworkers, including thirty-three Mohawks, lost their lives in an instant; through New York's skyscraper boom of the late 1920s, when ironworkers were hailed as "industrial age heroes." All the while, Rasenberger documents the lives of several contempor-ary ironworkers raising steel on a twenty-first-century skyscraper, the Time Warner building in New York City.This is a fast-paced, bare-knuckled portrait of vivid personalities, containing episodes of startling violence (as when ironworkers dynamited the Los Angeles Times building in 1910) and exhilarating adventure. In the end, High Steel is also a moving account of brotherhood and family. Many of those working in the trade today descend from multigenerational dynasties of ironworkers. As they walk steel, they follow in the footsteps of their fathers, grandfathers, and great-grandfathers.We've all had the experience of looking at a par-ticularly awe-inspiring bridge or building and wondering, How did they do that? Jim Rasenberger asks -- and answers -- the question behind the question: What sort of person would willingly scale such heights, take such chances, face such danger? The result is a depiction of the American working class as it has seldom appeared in literature: strong, proud, autonomous, enduring, and utterly compelling.
