The first book devoted to laser techniques in the generation and reception of ultrasonic waves in materials, Laser Ultrasonics: Techniques and Applications provides a full description of the state of the art in all fields involving both lasers and ultrasonics. This practical book focuses mainly on the possible applications of the techniques, yet theory is discussed wherever necessary. After an introduction to ultrasonics and laser technology, the book reviews acousto-optics, various acousto-optic devices, and noninterferometric optical methods of measuring ultrasonic displacements. The authors then describe opto-acoustic techniques, discussing laser interferometry, including reference-beam, velocity, and Fabry-Perot systems, and their application to ultrasonic measurement on different surfaces. The authors also detail the generation of ultrasound as a consequence of the absorption of laser light in material. The book proceeds to discuss applications of laser-generated ultrasound, both by itself and in combination with laser interferometric reception to form an entirely remote and non-contact measurement and testing system. Comparisons with nonoptical techniques for ultrasonic generation and detection are made where appropriate. The book concludes with a discussion of the future developments and uses of laser techniques in ultrasonics, with particular reference to nondestructive testing.

Covering all aspects of the subject, Signal Recovery from Noise in Electronic Instrumentation, Second Edition examines the interference involved with instruments that employ electronic techniques to measure physical quantities, including random fluctuations from thermal or background sources and systematic signal drift or offset. In the case of random noise, the book fully analyzes 1/f as well as white noise. It also discusses the theory and practice of baseline correction, low-pass filtering, multiple time averaging, and phase-sensitive detection. The author explores the best way of measuring the amplitude or the time of occurrence of a signal of known shape. New to this edition are an additional chapter, frequency measurement, and tutorial questions with answers to test understanding of the subject matter. This book will be indispensable to advanced electronics undergraduates, nonspecialist postgraduates using electronic instrumentation, and applied scientists.

Graphene is giving new impetus to the electronics industry because its band structure allows its properties to be dramatically altered and modified by chemical or electrochemical doping methods. This book provides a comprehensive source of information about graphene as a phenomenon, its physics and its mechanical and chemical properties in the light of the latest scientific and technological discoveries. The major focus of the book is on military and special applications since that is where the biggest investments are made.

The book opens with a description of the smooth transition from Newtonian to Einsteinian behaviour from electrons as their energy is progressively increased, and this leads directly to the relativistic expressions for mass, momentum and energy of a particle.

Provides the essential principles and results of special relativity as required by undergraduates. The text uses a geometric interpretation of space-time so that a general theory is seen as a natural extension of the special theory. Although most results are derived from first principles, complex and distracting mathematics is avoided and all mathematical steps and formulae are fully explained and interpreted, often with explanatory diagrams.; The emphasis throughout the text is on understanding the physics of relativity. The structure of the book is designed to allow students of different courses to choose their own route through the short self-contained sections in each chapter. The latter part of the book shows how Einstein's theory of gravity is central to unraveling fundamental questions of cosmology.

The opportunity to present the physics of radioactive processes in some detail apart from topics such as instrumentation which conventionally compete with it for spacer is most welcome. The material is intended to give a fairly complete introduction to radiation physics to those who which to have more than a descriptive understanding of the subject. Although it is possible to work one's way through much of the subject matter without having any previous physics background, some prior acquaintance with modern physics is desirable. A familiarity with calculus and differential equations is also assumed. Volume I begins with a brief description of classical physics, it's extension to special relativity and quantum mechanics, and an introduction to basic atomic and nuclear concepts. A thorough discussion of atomic structure follows with emphasis on the theory of the multielectron atom, characteristic X-rays, and the Auger effect. Volume II treats the subjects of nuclear structure, nuclear decay processes, the interaction of radiation with matter, and the mathematics of radioactive decay.

Current understanding of different phases as well as the phase transitions between them has only been achieved following recent theoretical advances on the effects of dimensionality in statistical physics. P S Pershan explains the connection between these two separate areas and gives some examples of problems where the understanding is still not complete. The most important example is the second order phase transition between the nematic and smectic-A phase. Others include the relation between the several hexatic phases that have been observed and the first order restacking transitions between phases that were all previously identified as smectic-B, but which should more properly be identified as crystalline-B. Some relatively recent experimental developments on the discotic phase, liquid crystal surfaces and lyotropic phases are also included. The book includes 41 major reprints of some of the recent seminal work on the structure of liquid crystals. They are introduced by a brief review of the symmetries and other properties of liquid crystalline phases. In addition, there is a discussion of the differences between true liquid crystalline phases and others that were described as liquid crystalline in the early literature, but which have since been shown to be true three-dimensional crystals. The progression from the isotropic fluid, through the nematic, smectic, and various crystalline phases can be understood in terms of a systematic decrease in symmetry, together with an accompanying variation in structure is explained. A guide to the selected reprints and a sort of "Rosetta Stone" for these various phases is provided. The goal of this book is to explain the systematics of this progression to students and others that are new to this field, as well as to provide a useful handbook for people already working in the field.

The book contains a comprehensive review of the physics, modelling and simulation of electron transport at interfaces in semiconductor devices.

The vital interconnections that rivers share with the land, the sky, and us Rivers are essential to civilization and even life itself, yet how many of us truly understand how they work? Why do rivers run where they do? Where do their waters actually come from? How can the same river flood one year and then dry up the next? Where the River Flows takes you on a majestic journey along the planet's waterways, providing a scientist's reflections on the vital interconnections that rivers share with the land, the sky, and us. Sean Fleming draws on examples ranging from common backyard creeks to powerful and evocative rivers like the Mississippi, Yangtze, Thames, and Congo. Each chapter looks at a particular aspect of rivers through the lens of applied physics, using abundant graphics and intuitive analogies to explore the surprising connections between watershed hydrology and the world around us. Fleming explains how river flows fluctuate like stock markets, what "digital rainbows" can tell us about climate change and its effects on water supply, how building virtual watersheds in silicon may help avoid the predicted water wars of the twenty-first century, and much more. Along the way, you will learn what some of the most exciting ideas in science--such as communications theory, fractals, and even artificial life--reveal about the life of rivers. Where the River Flows offers a new understanding of the profound interrelationships that rivers have with landscapes, ecosystems, and societies, and shows how startling new insights are possible when scientists are willing to think outside the disciplinary box.

Semiconducting oxides and nitrides are becoming the most important s- jects in materials science. In particular, zinc oxide (ZnO), gallium nitride (GaN), and related compounds form a novel class of semiconductors which possess unique properties in terms of crystallography, crystal growth, op- cal properties, electrical properties, magnetic properties, and so forth. These uniquepropertiesmakethesematerialsquiteimportantinoptoelectronicsand electronics. Although for more than three decades oxide and nitride semiconductors have been known to possess unique properties, it is only recently that these materials have been exploited to fabricate novel electronic and optical - vices, which havenever been possible with other semiconductors. It should be mentioned that revolutionary breakthroughs in materials science have been madebeforethe remarkabledevelopmentofsuchdevices.In particular, recent breakthrough and advance in epitaxy, bulk growth, and synthesis of nan- tructures coupled with exploration and investigation on structural, optical, and electrical properties, enabled us to achieve novel display, general lig- ing, optical storage, high-speed, -temperature and -power electronics, bio and environmental sensors, and energy generating and saving devices.

This book features a comprehensive review of experimental gravitation. It is a textbook based on the graduate courses on "Experimental Gravitation" given by the authors at their respective universities in Rome: Sapienza and Tor Vergata. A number of different research topics in the field are covered: from the torsion pendulum (still today the tool of choice for measuring small forces or torques) to the large interferometers developed to observe gravitational waves. Techniques that are still under development are also discussed, like the pulsar timing array and space-based detectors of the future. This book is written by experimentalists for experimentalists. While the background physics is summarized for less experienced readers, the emphasis is certainly on experimental verifications: the strategy, the apparatuses, the data analysis and the results of many cornerstone experiments are analyzed and discussed in depth. This textbook serves as a useful resource for both graduate students and professionals working in the increasingly vibrant field of experimental gravity.
