Engineers face many challenges in systems design and research. Modeling and Approximation in Heat Transfer describes the approach to engineering solutions through simplified modeling of the most important physical features and approximating their behavior. Systematic discussion of how modeling and associated synthesis can be carried out is included - in engineering practice, these steps very often precede mathematical analysis or the need for precise results.
Introduction to heat and mass transfer for advanced undergraduate and graduate engineering students, used in classrooms for over 38 years and updated regularly. Topics include conduction, convection, radiation, and phase-change. 2019 edition.
Presents a comprehensive introduction to the selection,operation, and testing of infrared devices, including adescription of modern detector assemblies and theiroperation This book discusses how to use and test infrared and visibledetectors. The book provides a convenient reference for thoseentering the field of IR detector design, test or use, those whowork in the peripheral areas, and those who teach and train othersin the field. Chapter 1 contains introductory material. Radiometry is coveredin Chapter 2. The author examines Thermal detectors in Chapter 3;the “Classical” photon detectors – simplephotoconductors and photovoltaics in Chapter 4; and “ModernPhoton Detectors” in Chapter 5. Chapters 6 through 8consider respectively individual elements and small arrays ofelements the “readouts” (ROICs) used with large imagingarrays; and Electronics for FPA Operation and Testing. The Test Setand The Testing Process are analyzed in Chapters 9 and 10, withemphasis on uncertainty and trouble shooting. Chapters 11 through15 discuss related skills, such as Uncertainty, Cryogenics, Vacuum,Optics, and the use of Fourier Transforms in the detector business.Some highlights of this new edition are that it Discusses radiometric nomenclature and calculations, detectormechanisms, the associated electronics, how these devices aretested, and real-life effects and problems Examines new tools in Infrared detector operations,specifically: selection and use of ROICs, electronics for FPAoperation, operation of single element and very small FPAs,microbolometers, and multi-color FPAs Contains five chapters with frequently sought-after informationon related subjects, such as uncertainty, optics, cryogenics,vacuum, and the use of Fourier mathematics for detectoranalyses Fundamentals of Infrared and Visible Detector Operation andTesting, Second Edition, provides the background and vocabularynecessary to help readers understand the selection, operation, andtesting of modern infrared devices.
Modern is a word much used, but hard to pin down. In Inventing Modern, John H. Lienhard uses that word to capture the furious rush of newness in the first half of 20th-century America. An unexpected world emerges from under the more familiar Modern. Beyond the airplanes, radios, art deco, skyscrapers, Fritz Lang's Metropolis, Buck Rogers, the culture of the open road--Burma Shave, Kerouac, and White Castles--lie driving forces that set this account of Modern apart. One force, says Lienhard, was a new concept of boyhood--the risk-taking, hands-on savage inventor. Driven by an admiration of recklessness, America developed its technological empire with stunning speed. Bringing the airplane to fruition in so short a time, for example, were people such as Katherine Stinson, Lincoln Beachey, Amelia Earhart, and Charles Lindbergh. The rediscovery of mystery powerfully drove Modern as well. X-Rays, quantum mechanics, and relativity theory had followed electricity and radium. Here we read how, with reality seemingly altered, hope seemed limitless. Lienhard blends these forces with his childhood in the brave new world. The result is perceptive, engaging, and filled with surprise. Whether he talks about Alexander Calder (an engineer whose sculptures were exercises in materials science) or that wacky paean to flight, Flying Down to Rio, unexpected detail emerges from every tile of this large mosaic. Inventing Modern is a personal book that displays, rather than defines, an age that ended before most of us were born. It is an engineer's homage to a time before the bomb and our terrible loss of confidence--a time that might yet rise again out of its own postmodern ashes.
Outstanding undergraduate text provides a thorough understanding of fundamentals and creates the basis for higher-level courses. Numerous examples and extensive exercise sections of varying difficulty, plus answers to selected exercises. 1990 edition.
An uncommonly clear and cogent investigation and correlation of key aspects of theoretical nuclear physics by leading experts: the nucleus, nuclear forces, nuclear spectroscopy, two-, three- and four-body problems, nuclear reactions, beta-decay and nuclear shell structure.
The phase-integral method in mathematics, also known as the Wentzel-Kramers-Brillouin (WKB) method, is the focus of this introductory treatment. Author John Heading successfully steers a course between simplistic and rigorous approaches to provide a concise overview for advanced undergraduates and graduate students in mathematics and physics. Since the number of applications is vast, the text considers only a brief selection of topics and emphasizes the method itself rather than detailed applications. The process, once derived, is shown to be one of essential simplicity that involves merely the application of certain well-defined rules. Starting with a historical survey of the problem and its solutions, subjects include the Stokes phenomenon, one and two transition points, and applications to physical problems. An appendix and bibliography conclude the text.
Nobel Laureate's lucid treatment of kinetic theory of gases, elementary particles, nuclear atom, wave-corpuscles, atomic structure and spectral lines, much more. Over 40 appendices, bibliography.
In How Invention Begins, Lienhard reconciles the ends of invention with the individual leaps upon which they are built, illuminating the vast web of individual inspirations that lie behind whole technologies. He traces, for instance, the way in which thousands of people applied their combined inventive genius to airplanes, railroad engines, and automobiles. As he does so, it becomes clear that a collective desire, an upwelling of fascination, a spirit of the times--a Zeitgeist--laid its hold upon inventors. The thing they all sought to create was speed itself. Likewise, Lienhard shows that when we trace the astonishingly complex technology of printing books, we come at last to that which we desire from books--the knowledge, the learning, that they provide. Can we speak of speed or education as inventions? To do so, he concludes, is certainly no greater a stretch than it is to call radio or the telephone an "invention." Throughout this marvelous volume, Lienhard illuminates these webs of insight or inspiration by weaving a fabric of anecdote, history, and technical detail--all of which come together to provide a full and satisfying portrait of the true nature of invention.
In this sequel to The Way to Nicaea, Fr John Behr turns his attention to the fourth century, the era in which Christian theology was formulated as the Nicene faith, the common heritage of most Christians to this day. Engaging the best of modern scholarship, Behr provides a series of original, comprehensive, and insightful sketches of the theology of the key protagonists of the Nicene faith, presenting a powerful vision of Christian theology, centered upon Christ and his Passion. Part One, True God of True God, opens with a reflection on the nature of Christian theology, challenging common presuppositions, and an analysis and survey of the fourth century controversies, followed by studies of Alexander, Arius, the Council of Nicaea, and, Athanasius. Part Two, One of the Holy Trinity, provides analyses of the work of Basil of Caesarea, Gregory of Nazianzus, and Gregory of Nyssa, together with their opponents, in particular Eunomius and Apollinarius.
