Still relevant decades after its 1950 publication, this legendary reference text on aircraft stress analysis is considered the best book on the subject. It emphasizes basic structural theory, which remains unchanged with the development of new materials and construction methods, and the application of the elementary principles of mechanics to the analysis of aircraft structures.
Suitable for undergraduate students, this volume covers equilibrium of forces, space structures, inertia forces and load factors, shear and bending stresses, and beams with unsymmetrical cross sections. Additional topics include spanwise air-load distribution, external loads on the airplane, joints and fittings, deflections of structures, and special methods of analysis. Topics involving a knowledge of aerodynamics appear in final chapters, allowing students to study the prerequisite aerodynamics topics in concurrent courses.

An introduction to developments in chaos and related topics in nonlinear dynamics, including the detection and quantification of chaos in experimental data, fractals, and complex systems. Most of the important elementary concepts in nonlinear dynamics are discussed, with emphasis on the physical concepts and useful results rather than mathematical proofs and derivations. While many books on chaos are purely qualitative and many others are highly mathematical, this book fills the middle ground by giving the essential equations, but in the simplest possible form. It assumes only an elementary knowledge of calculus. Complex numbers, differential equations, and vector calculus are used in places, but those tools are described as required. The book is aimed at the student, scientist, or engineer who wants to learn how to use the ideas in a practical setting. It is written at a level suitable for advanced undergraduate and beginning graduate students in all fields of science and engineering.

This work gives an up-to-date account of the theory of dielectrics suitable for graduates and final-year undergraduates in physics, chemistry, electrical engineering and materials science. There is a concentration on the basic principles of the subject, without a detailed discussion of experimental data. The macroscopic behaviour of dielectric materials receives most attention; nevertheless an adequate introduction to the microscopic theory of dielectrics is given. The treatment is necessarily mathematical, but sufficient verbal explanations are given so that the physical ideas are not hidden beneath a morass of mathematical symbols. Detailed derivations of key results are provided in appendices, together with extensive lists of references and further general reading.

Since their rapid proliferation in the late 1960s and early 1970s, quadrupole mass spectrometers have had a profound impact across the physical sciences. Geometrically simple, yet behaviorally complex, these dynamic mass analyzers continue to facilitate remarkable breakthroughs in fields ranging from biochemical analysis to process control technology. Long regarded as the standard introduction to the field, Quadrupole Mass Spectrometry and Its Applications provides today's engineers and scientists with an authoritative, wide-ranging overview of the development and uses of quadrupoles. Beginning with the basic operating principles of quadrupole devices, the book moves from general explanations of the actions of radio-frequency fields to descriptions of their utilization in quadrupole mass filters, monopoles, three-dimensional quadrupole ion traps, and various time-of-flight spectrometers. A concluding series of chapters examines early applications of quadrupoles in atomic physics, gas chromatography, upper atmospheric research, medicine, and environmental studies. Superb writing from the field's foremost scientists along with the continued central role of quadrupoles in contemporary research make this volume as timely and relevant as ever.

Market: Those involved in the design and use of UHV component systems. Written 25 years ago, this book explains both the design and use of UHV systems and components, as well as the underlying physical principles on which the performance of the equipment depends. Because of its close association of these underlying physical principles with the practical problems inherent in UHV equipment, the book retains its value to this day.

Many books treat the physics of superconductivity; very few until now have covered the engineering. Superconducting Magnets meets this need, providing a complete theoretical basis for the quantitative engineering design of superconducting magnet systems, ranging from the small instrument magnets, now in everyday use as research tools, to the very large magnet systems used for work on thermonuclear fusion and magnetohydrodynamic power generation. Wilson devotes particular attention to the problem of stabilization, a crucial factor in the design process because of its bearing on the overall reliability of the completed system. He also describes the essential features of field and stress calculation, although in less detail, since they are covered extensively in other works. Other topics considered are measurement techniques, current supply (with emphasis on heat exchanging cryogenic current leads), superconducting materials, the major applications of superconducting magnets, and some practical techniques of magnet manufacture.

This volume represents a collection of authoritative reviews by internationally recognized experts in the field of middle infrared (mid-IR) coherent sources and their applications. The compilation describes the fundamental principles and state-of-the-art of practical solid-state sources in the mid-IR regions of the spectrum covering the 2-50 Am range. The described sources include, along with more traditional heterojunction semiconductor lasers, optical parametric oscillators, difference frequency generators, as well as the most recently developed broadband crystalline, quantum cascade and fiber lasers. The rapid advances in mid-IR science and technology have made these sources indispensable tools for a variety of applications in environmental monitoring and pollution control, agriculture and life sciences, and non-invasive disease diagnosis through breath analysis. Coherent mid-IR sources also offer important technologies for atmospheric chemistry, free-space communication, imaging, rapid detection of explosives, chemical and biological agents, narcotics, as well as for applications in air- and sea-borne security. In comparison to the previous volume on this subject in 2003, which focused mainly on the design and development of mid-IR sources, the emphasis in the present volume is shifted towards applications. The instructive nature of the book makes it an excellent text for practicing engineers, physicists and graduate students, who intend to develop or use mid-IR laser sources in various applications.

Engineers and scientists who develop and install electronic devices and circuits need to have a solid understanding of electromagnetic theory and the electromagnetic behavior of devices and circuits. In particular, they must be well-versed in electromagnetic compatibility, which minimizes and controls the side effects of interconnected electric devices. Designed to entice the practical engineer to explore some worthwhile mathematical methods, and to reorient the theoretical scientist to industrial applications, Electromagnetic Theory for Electromagnetic Compatibility Engineers is based on the author's courses taught in industrial settings. The book is a mathematically rigorous exposition of electromagnetic theory with applications in electromagnetic compatibility and high-speed digital design. The topics-ranging from Maxwell's theory and multi-conductor transmission line theory to S-matrix, antenna theory, and dielectric breakdown-were chosen because they have direct relevance to current electromagnetic compatibility problems encountered in the real world. With many worked examples and problem sets, the book relates the theory to practical experiences faced by practitioners. It is written both for physicists and mathematicians new to the field of electromagnetic compatibility and high-speed digital design, as well as established researchers in the field. It is also designed as an advanced undergraduate textbook for a course in electromagnetic theory.

This text provides the reader with a comprehensive understanding of the key ideas behind the physics of particle accelerators.

This book provides a challenging and stimulating introduction to the contemporary topics of complexity and criticality, and explores their common basis of scale invariance, a central unifying theme of the book.Criticality refers to the behaviour of extended systems at a phase transition where scale invariance prevails. The many constituent microscopic parts bring about macroscopic phenomena that cannot be understood by considering a single part alone. The phenomenology of phase transitions is introduced by considering percolation, a simple model with a purely geometrical phase transition, thus enabling the reader to become intuitively familiar with concepts such as scale invariance and renormalisation. The Ising model is then introduced, which captures a thermodynamic phase transition from a disordered to an ordered system as the temperature is lowered in zero external field. By emphasising analogies between percolation and the Ising model, the reader's intuition of phase transitions is developed so that the underlying theoretical formalism may be appreciated fully. These equilibrium systems undergo a phase transition only if an external agent finely tunes certain external parameters to particular values.Besides fractals and phase transitions, there are many examples in Nature of the emergence of such complex behaviour in slowly driven non-equilibrium systems: earthquakes in seismic systems, avalanches in granular media and rainfall in the atmosphere. A class of non-equilibrium systems, not constrained by having to tune external parameters to obtain critical behaviour, is addressed in the framework of simple models, revealing that the repeated application of simple rules may spontaneously give rise to emergent complex behaviour not encoded in the rules themselves. The common basis of complexity and criticality is identified and applied to a range of non-equilibrium systems. Finally, the reader is invited to speculate whether self-organisation in non-equilibrium systems might be a unifying concept for disparate fields such as statistical mechanics, geophysics and atmospheric physics.Visit for animations for the models in the book (available for Windows and Linux), solutions to exercises, as well as a list with corrections.

Albert Einstein may be best known as the wire-haired whacky physicist who gave us the theory of relativity, but that's just one facet of this genius's contribution to human knowledge and modern science. As Jozsef Illy expertly shows in this book, Einstein had an eminently practical side as well. As a youth, Einstein was an inveterate tinkerer in the electrical supply factory his father and uncle owned and operated. His first paid job was as a patent examiner. Later in life, Einstein contributed to many inventions, including refrigerators, microphones, and instruments for aviation. In published papers, Einstein often provided ways to test his theories and fundamental problems of the scientific community of his times. He delved deeply into a variety of technological innovations, most notably the gyrocompass, and consulted for industry in patent cases and on other legal matters. Einstein also provided explanations for common and mundane phenomena, such as the meandering of rivers. In these and other hands-on examples culled from the Einstein Papers, Illy demonstrates how Einstein enjoyed leaving the abstract world of theories to wrestle with the problems of everyday life. While we may like the idea of Einstein as a genius besotted by extra dimensions and too out-of-this-world to wear socks, The Practical Einstein gives ample evidence that this characterization is both incomplete and an unfair representation of a man who sought to explore the intricacies of nature, whether in theory or in practice.

This book provides an introduction to quantum cascade lasers, including the basic underlying models used to describe the device. It aims at giving a synthetic view of the topic including the aspects of the physics, the technology, and the use of the device. It should also provide a guide for the application engineer to use this device in systems. The book is based on lecture notes of a class given for Masters and beginning PhD students. The idea is to provide an introduction to the new and exciting developments that intersubband transitions have brought to the use of the mid-infrared and terahertz region of the electromagnetic spectrum. The book provides an introductory part to each topic so that it can be used in a self-contained way, while references to the literature will allow deeper studies for further research.

Advances in technology often rely on a world of photons as the basic units of light. Increasingly one reads of photons as essential to enterprises in Photonics and Quantum Technology, with career and investment opportunities. Notions of photons have evolved from the energy-packet crowds of Planck and Einstein, the later field modes of Dirac, the seeming conflict of wave and particle photons, to the ubiquitous laser photons of today. Readers who take interest in contemporary technology will benefit from learning what photons are now considered to be, and how our views of photons have changed - in learning about the various operational definitions that have been used for photons and their association with a variety of quantum-state manipulations that include Quantum Information, astronomical sources and crowds of photons, the boxed fields of Cavity Quantum Electrodynamics and single photons on demand, the photons of Feynman and Glauber, and the photon constituents of the Standard Model of Particle Physics. The narrative points to contemporary photons as causers of change to atoms, as carriers of messages, and as subject to controllable creation and alteration - a considerable diversity of photons, not just one kind. Our Changing Views of Photons: A Tutorial Memoir presents those general topics as a memoir of the author's involvement with physics and the photons of theoretical Quantum Optics, written conversationally for readers with no assumed prior exposure to science. It offers lay readers a glimpse of scientific discovery - of how ideas become practical, as a small scientific community reconsiders its assumptions and offers the theoretical ideas that are then developed, revised, and adopted into technology for daily use. For readers who want a more detailed understanding of the theory, three substantial appendices provide tutorials that, assuming no prior familiarity, proceed from a very elementary start to basics of discrete states and abstract vector spaces; Lie groups; notions of quantum theory and the Schroedinger equation for quantum-state manipulation; Maxwell's equations for electromagnetism, with wave modes that become photons, possibly exhibiting quantum entanglement; and the coupling of atoms and fields to create quasiparticles. The appendices can be seen as a companion to traditional textbooks on Quantum Optics.

This work gives accounts of non-quantum optical phenomena and of instruments and technology based on them, at a level suitable for the last two years of an honours degree in physics and for graduates starting out. Topics covered include the conventional (diffraction, coherence, thin films, holography) and the less conventional (etendue, Gaussian beams, laser cavities, CD reader, confocal microscope) which belong in today's university courses, for example, to support laser physics. Even the conventional material has frequently been given a fresh presentation by giving a tidier-than-usual route through a calculation, or finding insightful connections with other parts of physics, or simply avoiding common errors. Problems offer opportunities for checking the reader's basic understanding, or for taking a careful route through reasoning, or for checking orders of magnitude. But most problems contain exploratory and critical material: investigating possible alternative approaches, asking searching questions about fundamentals, or solving apparent paradoxes.

Spatial change occurs whenever objects possess different spatial attributes at different times. This book discusses in detail the ingredients for a theory of qualitative spatial change: time, space, objects, their spatial attributes, and how these can vary. It provides a solid formal and theoretical basis for the computational modelling of spatial change.

Man versteht unter Technologie u. a. die Verarbeitung von Werk- stoffen zu betriebssicheren Produkten. Ein MaB fiir Betriebssicherheit ist z. B. die Lebensdauer, die ein Erzeugnis, das keiner Reparatur zuganglich ist, erreichen muB. Extreme Forderungen sind dabei urn so schwerer zu erfUllen, je vielgestaltiger das Produkt ist. Ein besonders komplexes Gebilde, an das hochste Anspriiche beziig- lich Lebensdauer gestellt werden, ist die Elektronenrohre. Sie ist fUr die Vakuumelektronik seit vielen Jahren von besonderer Bedeutung, und manche Pionierarbeit auf dem Weg zur modernen Technologie war an ihr zu leisten. Wenn sie oft nur noch als Dberbleibsel aus alten Zeiten angesehen wird, mag dies beziiglich der im taglichen Leben offen zutageliegenden Anwendung von Elektronik zutreffen. Doch dort, wo sie ihre Dienste mehr "im Verborgenen" zu verrichten hat, ist sie auch heute noch von "kriiftigem Leben" erfU11t. Wenn wir z.

Damit ist sie ausgezeichnetes Objekt fUr die Erorterung eines Querschnitts durch dieses Gebiet. Man kann sicher sein, dabei viele niitzliche und verwertbare Hinweise fUr andere Gebiete der Vakuumelektronik zu geben. Der Zweck dieses Buches ist, gewonnene Erfahrungen von den Grund- lagen her in moglichst verstandlicher Form weiterzugeben.
