Semiconductors and Modern Electronics is a brief introduction to the physics behind semiconductor technologies. Chuck Winrich explores the topic of semiconductors from a qualitative approach to understanding the theories and models used to explain semiconductor devices, which is intended to bring the advanced ideas behind semiconductors to a broader audience of students who will not major in physics. Applications of semiconductors are explored and understood through the models developed in the book. Much of the inspiration for this text comes from Winrich's experience teaching a general electronics course to students majoring in business. The goal of that class, and this work, is to bring forward the science behind semiconductors, and then to look at how that science affects the lives of people.
This third edition of Peter Bernath's successful Spectra of Atoms and Molecules is designed to provide advanced undergraduates and graduate students a working knowledge of the vast field of spectroscopy. Also of interest to chemists, physicists, astronomers, atmospheric scientists, and engineers, this volume emphasizes the fundamental principles of spectroscopy with the primary goal of teaching the interpretation of spectra. Features include a presentation of group theory needed to understand spectroscopy, detailed worked examples and a large number of excellent problems at the end of each chapter. Prof. Bernath provides a large number of diagrams and spectra which have been specifically recorded for this book. Molecular symmetry, matrix representation of groups, quantum mechanics, and group theory are among the topics covered; atomic, rotational, vibrational, electronic and Raman spectra are analyzed. Bernath's clear treatment of the confusing topic of line strengths as needed for quantitative applications is featured. This much-needed new edition has been updated to include the 2010 CODATA revision of physical constants, and a large number of corrections and clarifications. Responding to student requests, the main new feature is the addition of detailed worked examples in each chapter. Spectra of Atoms and Molecules, 3e will help demystify spectroscopy by showing readers the necessary steps in a derivation, as well as the final result.
Foundations of Engineering Acoustics takes the reader on a journey
from a qualitative introduction to the physical nature of sound,
explained in terms of common experience, to mathematical models and
analytical results which underlie the techniques applied by the
engineering industry to improve the acoustic performance of their
products. The book is distinguished by extensive descriptions and
explanations of audio-frequency acoustic phenomena and their
relevance to engineering, supported by a wealth of diagrams, and by
a guide for teachers of tried and tested class demonstrations and
laboratory-based experiments.
The nuclear Nonproliferation Treaty (NPT) is the cornerstone of nonproliferation and disarmament efforts, yet its negotiation and success was not inevitable. This book aims to address the developments that led to the negotiation of the treaty, examine its implementation, and address challenges that the NPT faces going forward. It begins with an overview of precursor efforts to establish international limits on nuclear weapons and why these efforts failed. It also looks at the changes in the political environment and technical advances, which together increased the threat of proliferation and drove states to negotiate the NPT. The second chapter considers the negotiation of the treaty itself and looks at the gap between US and Soviet positions on key areas like alliance control of nuclear weapons, and how the two governments found common ground on nonproliferation language. It also explores the critical role played by the non-aligned movement to push inclusion of disarmament provisions that would become the foundation for Article VI of the treaty and the hesitancy of nuclear-armed states to support disbarment language and timelines. Chapter 3 of the book focuses on implementation of the NPT and its initial successes in heading off states with nuclear weapons research programs. It addresses how the treaty responded to challenges like the dissolution of the Soviet Union and gaps identified by the illicit nuclear weapons programs in Iraq and North Korea in the early 1990s. Chapter 3 also includes a section on the debate in 1995 over extending the treaty indefinitely, and the compromises reached to satisfy the concerns of the non-nuclear weapon states. Finally, Chapter 4 addresses some of the outstanding challenges to the NPT that remain unresolved, such as the continued failure to convene a conference on the Middle East WMD-free zone and specify the consequences of withdrawing from the NPT, and repurposing civilian nuclear technology transferred under the treaty weapons purposes. It also looks at how the ban treaty under negotiations in the United Nations will support or undermine the NPT's objectives.

Nanogels are three-dimensional nanosized networks that are formed by physically or chemically cross-linking polymers. They have been explored as a drug-delivery system due to their biocompatibility, high stability, particle-size adjustment, drug-loading capability and modification of the surface for active targeting by cognate receptors on the target cells of tissues. Nanogels can respond to stimuli such as pH, temperature, light and redox, which results in the controlled release of drugs and targeting of site by environmental stimuli and prevents accumulation in non-target tissues, minimizing the side effects of the drug. This book aims to provide a general introduction to nanogels and the design of various stimuli-sensitive nanogels that can control drug release in response to specific stimuli.
Paleomagnetism is the study of the fossil magnetism in rocks. It
has been paramount in determining that the continents have drifted
over the surface of the Earth throughout geological time. The
fossil magnetism preserved in the ocean floor has demonstrated how
continental drift takes place through the process of sea-floor
spreading. The methods and techniques used in paleomagnetic studies
of continental rocks and of the ocean floor are described and then
applied to determining horizontal movements of the Earth's crust
over geological time. An up-to-date review of global paleomagnetic
data enables 1000 million
The Seventh International Conference series on Vision in Vehicles
was held in Marseilles in September 1997. This event was run in
conjunction with the Applied Vision Association, the Ergonomics
Society and with the participation of INRETS (Institut National de

Intended a both a textbook and a reference, Fourier Acoustics
develops the theory of sound radiation uniquely from the viewpoint
of Fourier Analysis. This powerful perspective of sound radiation
provides the reader with a comprehensive and practical
understanding which will enable him or her to diagnose and solve
sound and vibration problems in the 21st Century. As a result of
this perspective, Fourier Acoustics is able to present thoroughly
and simply, for the first time in book form, the theory of
nearfield acoustical holography, an important technique which has
revolutionised the measurement of sound. Relying little on material
outside the book, Fourier Acoustics will be invaluable as a
graduate level text as well as a reference for researchers in
academia and industry.
Elements of Photoionization Quantum Dynamics Methods focuses on the RMT approach for multiphoton quantum dynamics, which is employed to tackle the problem of laser-induced atomic dynamics. This recently developed formulation has shown the potential to become one of the mainstream ab initio theoretical approaches capable of describing the quantum dynamics of multielectron quantum systems exposed in ultrashort intense laser pulses lasting at the femtosecond timescale ( 10-15 sec). The method itself builds on the division-of-space concept and has evolved as an extension of the well-established atomic R-matrix method to incorporate time in its formulation. It is this way that its name was inherited, R-matrix with time incorporation (RMT), although no R-matrix appears anywhere in the formulation.
The progress in device technologies are surveyed in this volume. Included are Si/ (Si-Ge) heterojunctions for high-speed integrated circuits. Schottky-barrier arrays in Si and Si-Ge alloys for infrared imaging, III-V quantum-well detector structures operated in the heterodyne mode for high-data-rate communications, and III-V heterostructures and quantum-wells for infrared transmissions.

techniques and research in this area.
Electrostatic accelerators have been at the forefront of modern technology since 1932, when Sir John Cockroft and Ernest Walton developed the first accelerator. Although the electrostatic accelerator field is more than 90 years old, the field and the number of accelerators is growing more rapidly than ever. This book provides an overview of the basic science and technology that underlies the electrostatic accelerator field so it can serve as a reference guide and textbook for accelerator engineers as well as students and researchers who work with electrostatic accelerators.

Since the earliest days of human existence, the clash of thunder and trembling of the hills has struck fear into the hearts of seasoned warriors and tribal villagers alike. Great gods, demi-gods, and heroes were created to explain the awesome, mysterious, and incomprehensibly powerful forces of Nature in a feeble attempt to make sense of the world around them. To our advanced scientific minds today, these explanations seem childish and ridiculous; however, the power to flatten thousands of square miles of ancient forest, create massive holes in the Earth itself, and cause mountains to tremble to their very roots are more than enough reason to believe. Indeed, perhaps our scientific advancement has caused us to not fully or completely appreciate the awesome scale and power that Nature can wield against us. The study of shock wave formation and dynamics begins with a study of waves themselves. Simple harmonic motion is used to analyze the physical mechanisms of wave generation and propagation, and the principle of superposition is used to mathematically generate constructive and destructive interference. Further development leads to the shock singularity where a single wave of immense magnitude propagates and decays through various media. Correlations with the fields of thermodynamics, meteorology, crater formation, and acoustics are made, as well as a few special applications. Direct correlation is made to events in Arizona, Siberia, and others. The mathematical requirement for this text includes trigonometry, differential equations, and large series summations, which should be accessible to most beginning and advanced university students. This text should serve well as supplementary material in a course covering discrete wave dynamics, applied thermodynamics, or extreme acoustics.
Our understanding of subatomic particles developed over many years, although a clear picture of the different particles, their interactions and their inter-relationships only emerged in the latter part of the twentieth century. The first subatomic particles to be investigated were those which exhibit readily observable macroscopic behavior, specifically these are the photon, which we observe as light and the electron, which is manifested as electricity. The true nature of these particles, however, only became clear within the last century or so. The development of the Standard Model provided clarification of the way in which various particles, specifically the hadrons, relate to one another and the way in which their properties are determined by their structure. The final piece, perhaps, of the final model, that is the means by which some particles acquire mass, has just recently been clarified with the observation of the Higgs boson. Since the 1970s it has been known that the measured solar neutrino flux was inconsistent with the flux predicted by solar models. The existence of neutrinos with mass would allow for neutrino flavor oscillations and would provide an explanation for this discrepancy. Only in the past few years, has there been clear experimental evidence that neutrinos have mass. The description of particle structure on the basis of the Standard Model, along with recent discoveries concerning neutrino properties, provides us with a comprehensive picture of the properties of subatomic particles. Part I of the present book provides an overview of the Standard Model of particle physics including an overview of the discovery and properties of the Higgs boson. Part II of the book summarizes the important investigations into the physics of neutrinos and provides an overview of the interpretation of these studies.

"This volume deals with the interaction of acoustic fields with bubbles in liquids, with emphasis on the principles of cavitation--the generation of bubbles in liquids by rapid changes, such as those introduced by ultrasound. When cavity bubbles implode they produce shock waves in the liquid. If cavitation is induced by turbulent flow, components can be damaged. These phenomena have important implications, particularly in underwater acoustics, one of the fastest growing fields in acoustics research. The Acoustic Bubble skillfully explains the physical processes involved in cavitation both by analogy and formulation, making the concepts accessible to those with a minimal background in mathematics. This book willbe of great interest to those engaged in research in a wide range of areas, from sonochemistry to the sensitization of explosives.
Since 1965, Advances in Magnetic and Optical Resonance has provided researchers with timely expositions of fundamental new developments in the theory of, experimentation with, and application of magnetic and optical resonance. |
