Merlin - The Power Behind the Spitfire, Mosquito and Lancaster: the Story of the Engine That Won the Battle of Britain and WWII... Merlin - The Power Behind the Spitfire, Mosquito and Lancaster: the Story of the Engine That Won the Battle of Britain and WWII (Paperback)
Graham Hoyland
R204 Discovery Miles 2 040 Ships in 12 - 17 working days

The most iconic planes of WWII, the Supermarine Spitfire, Hawker Hurricane, DeHavilland Mosquito and the Avro Lancaster, were all powered by one engine, the Rolls-Royce Merlin. The story of the Merlin is one of British ingenuity at its height, of artistry and problem-solving that resulted in a war-winning design. Published to coincide with the 75th anniversary of VE Day and the 80th anniversary of the start of the Battle of Britain, Merlin is the extraordinary story of the development of the Rolls-Royce engine that would stop Hitler from invading Britain and carry the war to the very heart of Germany. The story of the Merlin engine encompasses the history of powered flight, from the ingenuity of the Wright Brothers to the horrors of World War I, and from the first crossing of the Atlantic to the heady days of flying in the 1920s. There is also the extraordinary story of the Schneider Trophy - an international contest wherein nations poised on the precipice of war competed for engineering excellence in the name of progress. And at the heart of this story are the glamourous lives of the pilots, many of whom died in their pursuit of speed; the engineers, like Henry Royce of Rolls-Royce, who sketched the engine that would win WWII in the sand of his local beach; and perhaps most importantly the Lady Lucy Houston who after the Wall Street Crash singlehandedly funded the development of the engine and the iconic Spitfire. Never was so much owed by so many to so few - and without the Rolls-Royce Merlin engine, the few would have been powerless.

Whispers from the depths is more than just the story of the building of the Kariba Dam in the mid-1950s. Built in just five years against overwhelming odds, the dam is a monument to engineering excellence. Shrouded in political undertones, the construction of the dam was vital for the hydro-electric power it would provide for Zambia’s burgeoning copper industry. Little thought, however, appears to have been given to the future of the human and animal populations who lived in the valley that would be inundated when the dam was completed. The question has to be asked: Was this awe-inspiring man-made creation achieved at too high a cost in terms of the human suffering and environmental devastation it caused? Central to the story of Kariba was the fate of the Tonga people who had for centuries lived in the Gwembe valley, due to be flooded when the sluice gates were finally closed to halt the flow of the mighty Zambezi River. Approximately 57 000 people were forced to move from their ancestral homes, abandoning family graves and spiritual sites to the depths of Kariba's water. They became a dispersed people who have never been able to reunite as a cohesive society, never again been able to live peacefully on the banks of the river which gave them life. Animals, too, perished in their thousands despite the gallant efforts of wildlife personnel who mounted a hastily planned rescue mission known as Operation Noah. Whispers from the depths gives a voice to the all but forgotten BaTonga. It celebrates their unique culture but deplores the price they paid for progress – a price from which they themselves derived no benefit whatsoever.

'Thrilling ... High-definition history: tight, thrilling and beautifully researched' SUNDAY TIMES 'This book is a triumph' DAN SNOW 9.07 a.m., April 12, 1961. A top-secret rocket site in the USSR. A young Russian sits inside a tiny capsule on top of the Soviet Union's most powerful intercontinental ballistic missile - originally designed to carry a nuclear warhead - and blasts into the skies. His name is Yuri Gagarin and he is about to make history. Travelling at almost 18,000 miles per hour - ten times faster than a rifle bullet - Gagarin circles the globe in just 106 minutes. While his launch begins in total secrecy, within hours of his landing he has become a world celebrity - the first human to leave the planet. Beyond tells the thrilling story behind that epic flight on its sixtieth anniversary. It happened at the height of the Cold War as the US and USSR confronted each other across an Iron Curtain. Both superpowers took enormous risks to get a man into space first - the Americans in the full glare of the media, the Soviets under deep cover. Both trained their teams of astronauts to the edges of the endurable. In the end the race between them would come down to the wire. Drawing on extensive original research and the vivid testimonies of eyewitnesses, many of whom have never spoken before, Stephen Walker unpacks secrets that were hidden for decades and takes the reader into the drama - featuring the scientists, engineers and political leaders on both sides, and above all the American astronauts and their Soviet rivals battling for supremacy in the heavens.

Automation is undergoing a major transformation in scope and dimension and plays an increasingly important role in the global economy and in our daily lives. Engineers combine automated devices with mathematical and organizational tools to create complex systems for a rapidly expanding range of applications and human activities. The Springer Handbook of Automation incorporates these new developments and presents a widespread and well-structured conglomeration of new emerging application areas of automation. Besides manufacturing as a primary application of automation, the handbook contains new application areas such as medical systems and health, transportation, security and maintenance, service, construction and retail as well as production or logistics. This Springer Handbook is not only an ideal resource for automation experts but also for people new to this expanding field such as engineers, computer scientists, designers. It is edited by an internationally renowned and experienced expert.

Chapters in Part A explain the significant influence of automation on our life, on individuals, organizations, and society, in economic terms and context, and impacts of precision, accuracy and reliability with automatic and automated equipment and operations. The theoretical and scientific knowledge about the human role in automation is covered in Part B from the human-oriented and human-centered aspects of automation to be applied and operated by humans, to the human role as supervisor and intelligent controller of automation systems and platforms. This part concludes with analysis and discussion on the limits of automation to the best of our current understanding. Covering automation design from theory to building automation machines, systems, and systems-of-systems, Part C explains the fundamental elements of mechatronics, sensors, robots, and other components useful for automation, and how they are combined with control and automation software, including models and techniques for automation software engineering, and the automation of the design process itself. Chapters in Part D cover the basic design requirements for the automation and illustrate examples of how the challenging issues can be solved for the deign and integration of automation with respect to its main purpose: Continuous and discrete processes and industries, design techniques, criteria and algorithms for flow lines, and integrated automation. Concluding this part is the design for safety of automation, and of automation for safety. The main aspects of automation management are covered by the chapters in Part E: Cost effectiveness and economic reasons for the design, feasibility analysis, implementation, rationalization, use, and maintenance of particular automation; performance and functionality measures and criteria. Related also are the issues of how to manage automatically and control maintenance, replacement, and upgrading.

Economic issues arise in almost every water policy context. Water is of most concern when scarce, but physical scarcity is often overcome as human beings move water from place to place, sometimes creating monumental structures. The roles that cost and economic value play in water resource allocation are implicit, but often poorly understood. This second edition clarifies the role of economics and offers material that can be applied to water resource allocation problems around the world. Topics covered include: groundwater, floods and droughts, in situ uses of water, and institutions and law. New to the book is an exploration of water issues outside the United States as well as a new application of behavioral and experimental economics to the topic. A concise introduction to issues of water quality and quantity in both urban and agricultural settings, Water Resource Economics and Policy will be a valuable resource or text for students and researchers in the fields of agricultural economics, geography, law, and hydrology. Those involved in water resource agencies and private utilities will also find the book a useful reference. Acclaim for the first edition: 'This textbook is written for first-year graduate students and senior level undergraduates in economics. ... Graduate students in geography, water resources, and environmental management should also be interested. The well-done helpful diagrams and charts are those expected for a textbook in economics at this level. In every chapter many interesting real-world examples illustrate the concept being discussed. Some chapters have easy-to-read case studies set off from the text. ... I plan on keeping this excellent book as a shelf reference and would willingly adopt it for a class in water resource economics.' - Donald E. Agthe, Journal of the American Water Resources Association 'This is a much-needed book, which introduces the interested reader to the economics of water resource allocation, and analyzes relevant policy issues derived from all over the world. To the best of my knowledge, this is the first book which is focused on communicating the basic economic concepts that govern water resources allocation. ... The lively writing style of W. Douglass Shaw, which is enriched with excellent examples and case studies from various countries, makes this book an obvious choice for a textbook in relevant courses ... this excellent book should be a compulsory reading for all of us who work in the field of water resources management.' - Phoebe Koundouri, Ecological Economics

In 1981 the sudden collapse of two skywalks in Kansas City's Hyatt hotel killed 114 people and injured another 200. There never was a public trial, nor a full airing of everything that went wrong. Richard A. Serrano shared a Pulitzer Prize for his coverage of the disaster at the time; now he returns to the tragedy to learn all that went wrong, how it could have been avoided, and what lasting effects persist today-for engineering and the legal system, but most importantly those who suffered. Drawing on legal depositions, evidentiary material, and recollections from 240 survivors, first responders, and construction officials, Buried Truths and the Hyatt Skywalks is the story of this monumental catastrophe and what it teaches us today. The Friday evening Tea Dance was all the rage that summer of 1981. Each week the lobby filled with throngs of revelers, some celebrating atop the skywalks themselves. On July 17, without warning, the steel support systems buckled and the concrete and glass skywalks crashed onto the crowded lobby. The devastation reverberated far beyond the ruins. Firefighters, police officers, and paramedics suffered from deep depression, cycled through divorce, hit the bottle, and in some instances committed suicide. The hotel had been built using a new fast-track method with key construction decisions often made on the fly, including changing the skywalk design from six heavy hanger rods to twelve thinner poles. Within a year the skywalks were splintering inside. Even then the collapse could have been averted, but special inspection panels to check the hanging walkways were never opened. Though wholly avoidable, the Hyatt disaster did bring significant changes-some good and some problematic. Tougher industry guidelines were enforced for US construction projects. Police officers, firefighters, and health care workers are now treated for PTSD and other psychological trauma after working a tragic event. But the rush to settle all the Hyatt lawsuits helped usher in a controversial new era of nondisclosure agreements. Buried Truths and the Hyatt Skywalks explores America's worst structural engineering disaster. Though the world has moved on, survivors and witnesses still vividly recall that night. This is their story.
