One of the major challenges of modern space mission design is the orbital mechanics - determining how to get a spacecraft to its destination using a limited amount of propellant. Recent misions such as Voyager and Galileo required gravity assist maneuvers at several planets to accomplish theiir objectives. Today's students of aerospace engineering face the challenge of calculating these types of complex spacecraft trajectories. This classroom-tested textbook takes its title from an elective course which has been taught to senior undergraduates and first-year graduate students for the past 22 years. The subject of orbital mechanics is developed starting from the first principles, using Newton's laws of motion and the law of gravitation to prove Kepler's empirical laws of planetary motion. Unlike many texts the authors also use first principles to derive other important results including Kepler's equation, Lambert's time-of-flight equation, the rocket equation, the...

This is a concise solid state physics textbook written for undergraduate students majoring in materials science, electronics, and physics. It clarifies the philosophy underlying the various branches of solid state physics, explores the exciting and original ideas of great scientists, demonstrates the significance of the neat assumptions in a theory by means of detailed mathematical computations, and exposes the complicated nature of solid state experiments. This book aims to guide students through a journey for the beauty amidst complexity, without missing the delicate thoughts contained in theories. The book covers the basic concepts, theories, and experiments about the structure of solids and their electrical, magnetic, thermal, sonic, and optical properties. It also traces the history of solid state physics and discusses chemical bond, crystal formation, lattice vibration, magnetism, and dielectric constant. A basic science textbook as it is, this book can also be of...

This book describes how modern quantum field theory is capable of treating not only quantum field particles, but also objects with classical and quantum mechanical degrees of freedom, including thermal degrees of freedom. It thus provides a unified overviw of many areas of physics on the basis of the concept of macroscopic quantum vacuum. - This text refers to an out of print or unavailable edition of this title.

Issues of movement – of people, things, information and ideas – are central to people?s lives and to most organisations. From oil wars to SMS texting, from airport expansion controversies to the decline of walking, from slave–trading to global terrorism, from global warming to teleworking, issues of ‘mobility’ are centre–stage upon many academic and policy agendas. These topics and issues are increasingly analysed as part of a concern with ‘mobility’ which this wide–ranging book both describes and seeks to develop. John Urry has been at the centre of these debates and he draws upon an extensive array of new research and material to develop what he calls the ‘new mobilities paradigm’ for the social sciences. He shows how this paradigm makes comprehensible social phenomena which were previously opaque. He examines how ‘mobilities’ each presuppose a ‘system’ that permits predictable and relatively risk–free repetition. The book outlines various such systems and then analyses their...

The hydrogen impurity in silicon is a very important defect, and has been studied both theoretically and experimentally for a considerable time. It has a wide range of physical effects, and is often deliberately introduced to saturate dangling bonds and hence improve the quality of interfaces such as with Si/Si02. It also has a number of less desirable effects, such as passivating both acceptor and donor defects (i.e. it is amphoteric) and can also enhance the diffusion of oxygen - another common defect. Since it has such significant effects, it is important to have a thorough microscopic understanding of the structure and properties of this defect. Формат: 16,5 см x 24 см.

The emergence of nanoelectronics has led us to renew the concepts of transport theory used in semiconductor device physics and the engineering community. It has become crucial to question the traditional semi-classical view of charge carrier transport and to adequately take into account the wave-like nature of electrons by considering not only their coherent evolution but also the out-of-equilibrium states and the scattering effects. This book gives an overview of the quantum transport approaches for nanodevices and focuses on the Wigner formalism. It details the implementation of a particle-based Monte Carlo solution of the Wigner transport equation and how the technique is applied to typical devices exhibiting quantum phenomena, such as the resonant tunnelling diode, the ultra-short silicon MOSFET and the carbon nanotube transistor. In the final part, decoherence theory is used to explain the emergence of the semi-classical transport in nanodevices.

"In a world of huge, interconnected networks that can be completely blacked out by disturbances, POWER SYSTEM PROTECTION offers you an improved understanding of the requirements necessary for prompt and accurate corrective action. P. M. Anderson, a noted expert on power systems, presents an analytical and technical approach to power system protection. His discussion shows how abnormal system behavior can be detected before damage occurs, and points to effective control action to limit system outages. Advance your knowledge of power system protection through a better understanding of: Protective devices and controls Protection concepts Transmission protection Apparatus protection System aspects of protective systems Reliability analysis of protective systems POWER SYSTEM PROTECTION is expressly written for practicing engineers and advanced graduate-level student engineers who need a comprehensive resource on the...

Recent improvements in LED technology have made them as ubiquitous as cell phones. In fact, LEDs light up almost all cell phones screens. The technology’s myriad applications and low energy use have made it nearly impossible to get through daily chores without coming in contact with LEDs. Probable advances include increased ability of the technology to support more efficient lighting and enhanced communications. With balanced coverage of the basics and future developments, Introduction to Light Emitting Diode Technology and Applications takes you on a tour of the LED evolution. The book begins with a brief history of the effort to enable the device that generates light through modern organic LEDs and reviews the fundamentals and principles of light prior to a detailed explanation of how LEDs generate different colors. After forming this basic foundation, the book examines the key LEDs in lighting and communications. It then discusses the latest opportunities and...

The Magnus effect is the phenomenon whereby a spinning object flying in a fluid creates a whirlpool of fluid around itself, and experiences a force perpendicular to the line of motion. The overall behaviour is similar to that around an aerofoil (see lift force) with a circulation which is generated by the mechanical rotation, rather than by aerofoil action.
