Excerpt: ...problem whether a maximum of a minimum occurs, or neither. For instance, if the problem is to determine the speed at which the efficiency of a motor is a maximum, the solution: speed=0, obviously is not a maximum but a mimimum, as at zero speed the efficiency is zero. If the problem is, to find the current at which the output of an alternator is a maximum, the solution i = 0 obviously is a minimum, and of the other two solutions, ii and t2, the larger value, %%, again gives a minimum, zero output at short-circuit current, while the intermediate value i gives the maximum. 101. The extremes of a function, therefore, are determined by equating its differential quotient to zero, as is illustrated by the following examples: Example 4. In an impulse turbine, the speed of the jet (steam jet or water jet) is Si. At what peripheral speed S2 is the output a maximum. The impulse force is proportional to the relative speed of the jet and the rotating impulse wheel; that is, to (S1-S2). The power is impulse force times speed S2; hence, P = kS2Sy-S2), (3) and is an extreme for the value of S2, given by-r-r = 0; hence, do 2 Si-2S2=0 and S2=y: (4) that is, when the peripheral speed of the impulse wheel equals half the jet velocity. Example 5. In a transformer of constant impressed e.m.f. Co = 2300 volts; the constant loss, that is, loss which is independent of the output (iron loss), is Pt-= 500 watts. The internal resistance (primary and secondary combined) is r = 20 ohms. At what current i is the efficiency of the transformer a maximum; that is, the percentage loss, X, a minimum? The loss is P= Pt +ri2 = 500+20i2 (5) The power input is Pi =et = 2300i;.... (6) hence, the percentage loss is, x P, ei' n and this is an extreme for the value of current i, ..

Download or read book When Computers Were Human written by David Alan Grier and published by Princeton University Press. This book was released on 2013-11-01 with total page 423 pages. Available in PDF, EPUB and Kindle. Book excerpt: Before Palm Pilots and iPods, PCs and laptops, the term "computer" referred to the people who did scientific calculations by hand. These workers were neither calculating geniuses nor idiot savants but knowledgeable people who, in other circumstances, might have become scientists in their own right. When Computers Were Human represents the first in-depth account of this little-known, 200-year epoch in the history of science and technology. Beginning with the story of his own grandmother, who was trained as a human computer, David Alan Grier provides a poignant introduction to the wider world of women and men who did the hard computational labor of science. His grandmother's casual remark, "I wish I'd used my calculus," hinted at a career deferred and an education forgotten, a secret life unappreciated; like many highly educated women of her generation, she studied to become a human computer because nothing else would offer her a place in the scientific world. The book begins with the return of Halley's comet in 1758 and the effort of three French astronomers to compute its orbit. It ends four cycles later, with a UNIVAC electronic computer projecting the 1986 orbit. In between, Grier tells us about the surveyors of the French Revolution, describes the calculating machines of Charles Babbage, and guides the reader through the Great Depression to marvel at the giant computing room of the Works Progress Administration. When Computers Were Human is the sad but lyrical story of workers who gladly did the hard labor of research calculation in the hope that they might be part of the scientific community. In the end, they were rewarded by a new electronic machine that took the place and the name of those who were, once, the computers.

Download or read book Creators of Mathematical and Computational Sciences written by Ravi P Agarwal and published by Springer. This book was released on 2014-11-11 with total page 514 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book records the essential discoveries of mathematical and computational scientists in chronological order, following the birth of ideas on the basis of prior ideas ad infinitum. The authors document the winding path of mathematical scholarship throughout history, and most importantly, the thought process of each individual that resulted in the mastery of their subject. The book implicitly addresses the nature and character of every scientist as one tries to understand their visible actions in both adverse and congenial environments. The authors hope that this will enable the reader to understand their mode of thinking, and perhaps even to emulate their virtues in life.
Download or read book Fiber Optics Engineering written by Mohammad Azadeh and published by Springer Science & Business Media. This book was released on 2009-08-05 with total page 378 pages. Available in PDF, EPUB and Kindle. Book excerpt: Within the past few decades, information technologies have been evolving at a tremendous rate, causing profound changes to our world and our ways of life. In particular, fiber optics has been playing an increasingly crucial role within the telecommunication revolution. Not only most long-distance links are fiber based, but optical fibers are increasingly approaching the individual end users, providing wide bandwidth links to support all kinds of data-intensive applications such as video, voice, and data services. As an engineering discipline, fiber optics is both fascinating and challenging. Fiber optics is an area that incorporates elements from a wide range of techno- gies including optics, microelectronics, quantum electronics, semiconductors, and networking. As a result of rapid changes in almost all of these areas, fiber optics is a fast evolving field. Therefore, the need for up-to-date texts that address this growing field from an interdisciplinary perspective persists. This book presents an overview of fiber optics from a practical, engineering perspective. Therefore, in addition to topics such as lasers, detectors, and optical fibers, several topics related to electronic circuits that generate, detect, and process the optical signals are covered. In other words, this book attempts to present fiber optics not so much in terms of a field of “optics” but more from the perspective of an engineering field within “optoelectronics.
Download or read book An American Engineer in Stalin s Russia written by Zara Witkin and published by Univ of California Press. This book was released on 2023-11-10 with total page 444 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1932 Zara Witkin, a prominent American engineer, set off for the Soviet Union with two goals: to help build a society more just and rational than the bankrupt capitalist system at home, and to seek out the beautiful film star Emma Tsesarskaia. His memoirs offer a detailed view of Stalin's bureaucracy—entrenched planners who snubbed new methods; construction bosses whose cover-ups led to terrible disasters; engineers who plagiarized Witkin's work; workers whose pride was defeated. Punctuating this document is the tale of Witkin's passion for Tsesarskaia and the record of his friendships with journalist Eugene Lyons, planner Ernst May, and others. Witkin felt beaten in the end by the lethargy and corruption choking the greatest social experiment in history, and by a pervasive evil—the suppression of human rights and dignity by a relentless dictatorship. Finally breaking his spirit was the dissolution of his romance with Emma, his "Dark Goddess." In his lively introduction, Michael Gelb provides the historical context of Witkin's experience, details of his personal life, and insights offered by Emma Tsesarskaia in an interview in 1989.
Download or read book Mathematicians Fleeing from Nazi Germany written by Reinhard Siegmund-Schultze and published by Princeton University Press. This book was released on 2009 with total page 501 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on archival sources that have never been examined before, the book discusses the preeminent emigrant mathematicians of the period, including Emmy Noether, John von Neumann, Hermann Weyl, and many others. The author explores the mechanisms of the expulsion of mathematicians from Germany, the emigrants' acculturation to their new host countries, and the fates of those mathematicians forced to stay behind. The book reveals the alienation and solidarity of the emigrants, and investigates the global development of mathematics as a consequence of their radical migration.
Download or read book What s Next written by Dylan Thurston and published by Princeton University Press. This book was released on 2020-07-07 with total page 436 pages. Available in PDF, EPUB and Kindle. Book excerpt: William Thurston (1946-2012) was one of the great mathematicians of the twentieth century. He was a visionary whose extraordinary ideas revolutionized a broad range of mathematical fields, from foliations, contact structures, and Teichm ller theory to automorphisms of surfaces, hyperbolic geometry, geometrization of 3-manifolds, geometric group theory, and rational maps. In addition, he discovered connections between disciplines that led to astonishing breakthroughs in mathematical understanding as well as the creation of entirely new fields. His far-reaching questions and conjectures led to enormous progress by other researchers. What's Next? brings together many of today's leading mathematicians to describe recent advances and future directions inspired by Thurston's transformative ideas. Including valuable insights from his colleagues and former students, What's Next? discusses Thurston's fundamental contributions to topology, geometry, and dynamical systems and includes many deep and original contributions to the field. This incisive and wide-ranging book also explores how he introduced new ways of thinking about and doing mathematics, innovations that have had a profound and lasting impact on the mathematical community as a whole.

Available in PDF, EPUB and Kindle. Book excerpt: A free ebook version of this title is available through Luminos, University of California Press’s Open Access publishing program. Visit www.luminosoa.org to learn more. When China’s War of Resistance against Japan began in July 1937, it sparked an immediate health crisis throughout China. In the end, China not only survived the war but emerged from the trauma with a more cohesive population. Intimate Communities argues that women who worked as military and civilian nurses, doctors, and midwives during this turbulent period built the national community, one relationship at a time. In a country with a majority illiterate, agricultural population that could not relate to urban elites’ conceptualization of nationalism, these women used their work of healing to create emotional bonds with soldiers and civilians from across the country. These bonds transcended the divides of social class, region, gender, and language.

Available in PDF, EPUB and Kindle. Book excerpt: Empire of the Air tells the story of three American visionaries—Lee de Forest, Edwin Howard Armstrong, and David Sarnoff—whose imagination and dreams turned a hobbyist's toy into radio, launching the modern communications age. Tom Lewis weaves the story of these men and their achievements into a richly detailed and moving narrative that spans the first half of the twentieth century, a time when the American romance with science and technology was at its peak. Empire of the Air is a tale of pioneers on the frontier of a new technology, of American entrepreneurial spirit, and of the tragic collision between inventor and corporation.
