Download or read book A History of Control Engineering 1930 1955 written by Stuart Bennett and published by IET. This book was released on 1993 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: Traces the consolidation of a specialty, as the various feedback control devices used in the 1930s for aircraft and ships, the telephone system, and analogue computers, were brought together during World War II to form what is now known as the classical frequency response methods of analysis and design, and applied to non-linear, sampled-data, and stochastic systems. Follows the field's development through the post-war addition of the root locus method to the introduction of the state-space methods of modern control. Distributed by INSPEC.

Book excerpt: "A fascinating history of the unexpected intersection of science, technology and show business." -John Steele Gordon, author of Hamilton's Blessing "Once upon a time, American know-how flourished through show-how: spectacular demonstrations by ever resourceful technological entrepreneurs. David Lindsay brings back these glorious (and sometimes infamous) theatricals in a delightful, witty, narrative with a serious point: the American inventor, now relegated to endless rehearsals, needs to resume a rightful place on the national center stage. For admirers and critics of technology and for veteran and inspiring inventors, Madness in the Making will give pleasure and inspire debate." -Edward Tenner. Author of Why Things Bite Back
Download or read book Articulation and Intelligibility written by Jont B. Allen and published by Springer Nature. This book was released on 2022-05-31 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: Immediately following the Second World War, between 1947 and 1955, several classic papers quantified the fundamentals of human speech information processing and recognition. In 1947 French and Steinberg published their classic study on the articulation index. In 1948 Claude Shannon published his famous work on the theory of information. In 1950 Fletcher and Galt published their theory of the articulation index, a theory that Fletcher had worked on for 30 years, which integrated his classic works on loudness and speech perception with models of speech intelligibility. In 1951 George Miller then wrote the first book Language and Communication, analyzing human speech communication with Claude Shannon's just published theory of information. Finally in 1955 George Miller published the first extensive analysis of phone decoding, in the form of confusion matrices, as a function of the speech-to-noise ratio. This work extended the Bell Labs' speech articulation studies with ideas from Shannon's Information theory. Both Miller and Fletcher showed that speech, as a code, is incredibly robust to mangling distortions of filtering and noise. Regrettably much of this early work was forgotten. While the key science of information theory blossomed, other than the work of George Miller, it was rarely applied to aural speech research. The robustness of speech, which is the most amazing thing about the speech code, has rarely been studied. It is my belief (i.e., assumption) that we can analyze speech intelligibility with the scientific method. The quantitative analysis of speech intelligibility requires both science and art. The scientific component requires an error analysis of spoken communication, which depends critically on the use of statistics, information theory, and psychophysical methods. The artistic component depends on knowing how to restrict the problem in such a way that progress may be made. It is critical to tease out the relevant from the irrelevant and dig for the key issues. This will focus us on the decoding of nonsense phonemes with no visual component, which have been mangled by filtering and noise. This monograph is a summary and theory of human speech recognition. It builds on and integrates the work of Fletcher, Miller, and Shannon. The long-term goal is to develop a quantitative theory for predicting the recognition of speech sounds. In Chapter 2 the theory is developed for maximum entropy (MaxEnt) speech sounds, also called nonsense speech. In Chapter 3, context is factored in. The book is largely reflective, and quantitative, with a secondary goal of providing an historical context, along with the many deep insights found in these early works.
Download or read book Power Speed and Form written by David P. Billington and published by Princeton University Press. This book was released on 2022-11-29 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Power, Speed, and Form is the first accessible account of the engineering behind eight breakthrough innovations that transformed American life from 1876 to 1939—the telephone, electric power, oil refining, the automobile, the airplane, radio, the long-span steel bridge, and building with reinforced concrete. Beginning with Thomas Edison's system to generate and distribute electric power, the authors explain the Bell telephone, the oil refining processes of William Burton and Eugene Houdry, Henry Ford's Model T car and the response by General Motors, the Wright brothers' airplane, radio innovations from Marconi to Armstrong, Othmar Ammann's George Washington Bridge, the reinforced concrete structures of John Eastwood and Anton Tedesko, and in the 1930s, the Chrysler Airflow car and the Douglas DC-3 airplane. These innovations used simple numerical ideas, which the Billingtons integrate with short narrative accounts of each breakthrough—a unique and effective way to introduce engineering and how engineers think. The book shows how the best engineering exemplifies efficiency, economy and, where possible, elegance. With Power, Speed, and Form, educators, first-year engineering students, liberal arts students, and general readers now have, for the first time in one volume, an accessible and readable history of engineering achievements that were vital to America's development and that are still the foundations of modern life.

Download or read book Theory and Synthesis of Linear Passive Time Invariant Networks written by Dante C. Youla and published by Cambridge University Press. This book was released on 2015-11-05 with total page 655 pages. Available in PDF, EPUB and Kindle. Book excerpt: Exploring the overlap of mathematics and engineering network synthesis, this book presents a rigorous treatment of the key principles underpinning linear lumped passive time-invariant networks. Based around a series of lectures given by the author, this thoughtfully written book draws on his wide experience in the field, carefully revealing the essential mathematical structure of network synthesis problems. Topics covered include passive n-ports, broadband matching, the design of passive multiplexes and two-state passive devices. It also includes material not usually found in existing texts, such as the theoretical behavior of transverse electromagnetic (TEM) coupled transmission lines. Introducing fundamental principles in a formal theorem-proof style, illustrated by worked examples, this book is an invaluable resource for graduate students studying linear networks and circuit design, academic researchers, and professional circuit engineers.
Download or read book Chance and Design written by Alan Hodgkin and published by Cambridge University Press. This book was released on 1994-01-28 with total page 432 pages. Available in PDF, EPUB and Kindle. Book excerpt: Alan Hodgkin believes that - contrary to popular conviction - chance plays quite as large a role as design in scientific discovery. This engaging autobiography charts the balance of the two in his own life. Beginning starts with an account of his childhood in an extended Quaker family. Not a great success at school, he nevertheless won a scholarship to Trinity College, Cambridge, and he writes informatively of the climate of university opinion in the thirties when he was an undergraduate and came to abandon the pacifist ideals of his upbringing. A chance observation on frog nerve led to a Trinity Fellowship and a year at the Rockefeller Institute in New York (where he met his future wife), to the Nobel Prize in 1963, and ultimately to the Presidency of the Royal Society. His experiments on nerve conduction seemed almost at the point of success when everything had to be abandoned on the outbreak of war in 1939, and for six years Hodgkin worked on the concept and design of airborne radar, described in the central section of the book as Flight Trials and Tribulations. The account of his return to civilian life and the resumption of experimentation includes two chapters of solid detail of Starting Again - for this is a book for any reader interested in the origin and development of a dedicated scientist.
