Barkhausen Noise for Nondestructive Testing and Materials Characterization in Low Carbon Steels presents a balanced approach, reviewing the disadvantages and advantages of using this technique and its comparison over other magnetic testing techniques. In addition, the book looks towards future applications of this technique, in particular, its industrial applications as a method for pipeline inspection, current advantages, and barriers to implementation. The book is suitable for materials scientists, researchers and engineers, and may be applicable for those working in metallurgical plants. Not only does the book discuss fundamentals, it reviews recent discoveries, such as the correlation between magnetocrystalline energy and Barkhausen noise, the modeling of this relationship, and the application of this technique in the characterization of magnetic materials.

The book contains the contributions presented at the NATO ARW on Ferrimagnetic Nano-crystalline and Thin Film Magnetooptical and Microwave Materials (short title: Nano-crystalline and Thin Film Magnetic Oxides) which took place in Sozopol, Bulgaria, Sept. 27 - Oct. 3, 1998. The program of the ARW was consistent with three main areas in the magnetic oxides for microwave and magnetooptical applications : thin films and nano-crystalline ferroxides; magnetic behaviour and applications of oxides with perovskite structures; and nano-sized materials and modeling. The development of planar devices for high-density magnetic and magneto- optical recording and microwave integral technologies has led to a substantial growth of the scientific interest in nano-crystallline and thin film magnetic oxides, such as ferrites, manganates and cuprates. The Workshop organizers embarked on the ambitious task to attract the scientists' attention to key problems related to the nano-crystalline state of magnetic oxides and their magnetic, electrical, and optical behaviour. The knowldege of interactions between charge carriers, with phonons, the spin and dipole magnetic moments and the role of the microstructure and magnetic anisotropy is much theoretically studied for magnetic oxides. The workshop program touched not only upon the theoretical aspects, but on the technology and experiments as well. A review of nano-particle technology and future trends was presented. The possibilities of investigating and modeling the domain structure of the magnetic oxide films were demonstrated and discussed. Microwave and magnetooptical applications of ferroxides were also explored, including a discussion on new types of components with nano-size structure.

Electromagnetic waves and their role in probing the earth are important for the exploration of the earth's deep crust. This book is not only for scientists in geophysics a useful source of information, but also for professionals in oil and gas exploration, geophysicists and engineers alike.

These Proceedings of a NATO-ARW (HTECH ARW 97 1843) held at the Oreanda Hotel, Yalta, Ukraine from April 29 till May 2, 1998 resulted from many discussions between various workers, concerning the need for a gathering of all (if possible) who were concerned with the subject of symmetry of the order parameter and pairing states for superconductivity. We applied ourselves in particular to High critical Temperature Superconductors (HTS), but also studied other unconventional superconductors. The study of HTS is one of the most prominent research subjects in solid state sciences. The understanding of the role of symmetry and pairing conditions are also thought to be necessary before technological applications since these features may be influenced by external fields. The workshop discussions have touched upon theoretical and experimental aspects, but also on related topics. These served as initiators for a very great amount of discussions with many comments from the audience. More than thirty "long lectures" and one on going "poster session" were held. Private discussions went unrecorded but obviously took place at many locations: lecture halls, staircases, cafes, bedrooms, bars, beach, bus, plane... Arguments openly reported for the first time were often quite sharp ones, -and this is an understatement."

The series of texts on Classical Theoretical Physics is based on the highly successful series of courses given by Walter Greiner at the Johann Wolfgang Goethe University in Frankfurt am Main, Germany. Intended for advanced undergraduates and beginning graduate students, the volumes in the series provide not only a complete survey of classical theoretical physics but also an enormous number of worked examples and problem to show students clearly how to apply the abstract principles to realistic problems.

The International Workshop on "Intersubband Transitions in Quantum Wells:: Physics and Applications," was held at National Cheng Kung University, in Tainan, Taiwan, December 15-18, 1997. The objective of the Workshop is to facilitate the presentation and discussion of the recent results in theoretical, experimental, and applied aspects of intersubband transitions in quantum wells and dots. The program followed the tradition initiated at the 1991 conference in Cargese-France, the 1993 conference in Whistler, B. C. Canada, and the 1995 conference in Kibbutz Ginosar, Israel. Intersubband transitions in quantum wells and quantum dots have attracted considerable attention in recent years, mainly due to the promise of various applications in the mid- and far-infrared regions (2-30 J. lm). Over 40 invited and contributed papers were presented in this four-day workshop, with topics covered most aspects of the intersubband transition phenomena including: the basic intersubband transition processes, multiquantum well infrared photodetector (QWIP) physics, large format (640x480) GaAs QWIP (with 9. 0 J. lffi cutoff) focal plane arrays (FPAs) for IR imaging camera applications, infrared modulation, intersubband emission including mid- and long- wavelength quantum cascade (QC) lasers such as short (A. "" 3. 4 J. lm) and long (A. "" 11. 5 J. lm) wavelength room temperature QC lasers, quantum fountain intersubband laser at 15. 5 J. lm wavelength in GaAs/AIGaAs quantum well, harmonic generation and nonlinear effects, ultra-fast phenomena such as terahertz (THz) intersubband emission and detection. The book divides into five Chapters.

Catalytic reactions on metals are still nowadays involved in more than half of the chemical industrial processes. The winter school held at "I 'Ecole de in March 1996, 13 years after the first one, accounts Physique des Houches" for an evolution of the field in several directions. First, the emulation between theoretical chemistry and solid state physics has emerged on heuristic concepts, leading not only to explanations of the observed phenomena but, for the first time, to predictions of the reactivity of catalytic systems and of the reaction pathways. The second domain which during these years has become of primary importance is the abatement of the pollution. It concerns not only the conversion of polluting effluents but more and more major modifications of the processes to avoid the production of undesired products. Two striking examples are the necessary catalytic conversion of the 100 000 cubic meter of hydrogen that would be produced in a major incident of a nuclear power plant and the replacement of the CFC. The valorization of agricultural supplies can already be considered as one of the major achievement of catalysis. Indeed, the carbon of biosustainable raw materials represents more than 2 orders of magnitude the amount extracted from fossil fuels each year. Moreover, the molecules are already highly functionalised in contrast with hydrocarbons which require costly steps to be converted to the same products. They are now of current use in the elaboration of cosmetics, vitamins, polymers, etc.

This book provides an introductory yet comprehensive account of James Clerk Maxwell's (1831-79) physics and world view. The argument is structured by a focus on the fundamental themes that shaped Maxwell's science: analogy and geometry, models and mechanical explanation, statistical representation and the limitations of dynamical reasoning, and the relation between physical theory and its mathematical description. This approach, which considers his physics as a whole, bridges the disjunction between Maxwell's greatest contributions: the concept of the electromagnetic field and the kinetic theory of gases. Maxwell's work and ideas are viewed historically in terms of his indebtedness to scientific and cultural traditions, of Edinburgh experimental physics, and of Cambridge mathematics and philosophy of science, which nurtured his career. Peter M. Harman is Professor of the History of Science at Lancaster University. He has published primarily on the history of physics and natural philosophy in the 18th and 19th centuries, the period from Newton to Maxwell. His previous books include Energy, Force, and Matter (Cambridge, 1982), The Investigation of Difficult Things (Cambridge, 1992), After Newton: Essays on Natural Philosophy (Variorum, 1993), The Scientific Letters and Papers of James Clerk Maxwell, volume 1 (Cambridge, 1990), volume 2 (Cambridge, 1995).

Physics on Your Feet (2nd Edition) is a significantly expanded collection of physics problems covering the broad range of topics in classical and modern physics that were, or could have been, asked at oral PhD exams at University of California at Berkeley.

Detailed solutions are provided, from which the reader is guaranteed to learn a lot about the physicists' way of thinking. The book is also packed full of cartoons and dry humor to help take the edge off the stress and anxiety surrounding exams. This is a helpful guide for students preparing for their exams, as well as a resource for university lecturers looking for good instructive problems. No exams are necessary to enjoy the book!

Market: Scientists, engineers, and graduate students in atomic physics, astrophysics, spectroscopy, atmospheric and solid state physics, and semiconductor research. Drawn from the author's lectures to undergraduates at Oxford University, this 1955 work features probing analyses of many problems in atomic physics, plasma physics, spectroscopy, atmospheric and solid state physics. By emphasizing fundamental concepts and the limitations of treatments rather than the details of theories, this book has become a valued reference tool both in academia and among professionals in the scientific community.

This volume contains four sections in addition to the previous sections of electrodynamics II, which were concerned with the two-particle problem, and applications to hydrogenic atoms, positronium, and muonium. Although the major objective here is an improved treatment of the electron magnetic moment, attention is also given to the effect of string magnetic fields, to an extended treatment of photon propagation function, and to a confrontational discussion on the pion decay into two photons.

This work presents a comprehensive theory describing atomic diffusion in silicon crystals under strong nonequilibrium conditions caused by ion implantation and interaction with the surface or other interfaces. A set of generalized equations that describe diffusion of impurity atoms and point defects are presented in a form suitable for solving numerically. Based on this theory, partial diffusion models are constructed, and the simulation of many doping processes used in microelectronics is carried out.Coupled Diffusion of Impurity Atoms and Point Defects in Silicon Crystals is a useful text for researchers, engineers, and advanced students in semiconductor physics, microelectronics, and nanoelectronics. It helps readers acquire a deep understanding of the physics of diffusion and demonstrates the practical application of the theoretical ideas formulated to find cheaper solutions in the course of manufacturing semiconductor devices and integrated microcircuits.

The experimental discovery of the fractional quantum Hall effect (FQHE) at the end of 1981 by Tsui, Stormer and Gossard was absolutely unexpected since, at this time, no theoretical work existed that could predict new struc tures in the magnetotransport coefficients under conditions representing the extreme quantum limit. It is more than thirty years since investigations of bulk semiconductors in very strong magnetic fields were begun. Under these conditions, only the lowest Landau level is occupied and the theory predicted a monotonic variation of the resistivity with increasing magnetic field, depending sensitively on the scattering mechanism. However, the ex perimental data could not be analyzed accurately since magnetic freeze-out effects and the transitions from a degenerate to a nondegenerate system complicated the interpretation of the data. For a two-dimensional electron the positive background charge is well separated from the two gas, where dimensional system, magnetic freeze-out effects are barely visible and an analysis of the data in the extreme quantum limit seems to be easier. First measurements in this magnetic field region on silicon field-effect transistors were not successful because the disorder in these devices was so large that all electrons in the lowest Landau level were localized. Consequently, models of a spin glass and finally of a Wigner solid were developed and much effort was put into developing the technology for improving the quality of semi conductor materials and devices, especially in the field of two-dimensional electron systems."

This monograph presents electric therapy for the reduction of pain in a different way than the classical well known manner to use electric currents of various kinds for this purpose. It started when Melzack and Wall published their theory of pain. But contrary to most researchers, the author looked for a proof which objectively could demonstrate, that electric current would have an influence on nerve fibers conducting pain. Starting from this model of demonstration, an optimal type of current could be selected as well as optimal electrode positions and sizes of electrodes. It is an absolute new approach presenting the results of applying the type of current to more than 17.000 patients suffering from any kind of pain. Anatomic sketches and photo-documentation of electrode positions for many conditions allow the reader to obtain identical degree of pain reduction as the author describes from his great experience. In addition, a brief theoretical introduction and discussion of the influence of weather on pain is given. Practical forms for the management of pain are presented in an appendix. 256 references and a table of suitable apparatus with their essential technical characteristics facilitates correct application of this new principle.

Lightning Physics and Lightning Protection presents a comprehensive and up-to-date review of lightning, including its hazards and protection techniques. The authors first discuss the effectiveness of conventional protective measures, supply technical advice and practical recommendations, and explore the prospects for the preventive control of a lightning leader, followed by a discussion of the initiation of a leader and return stroke and subsequent components. After including measurements useful for understanding lightning and its effects, the book describes the mechanism of lightning discharge processes. It then examines the effects of large aircraft, high-voltage lines, and other high-altitude constructions on lightning trajectory and leader attraction. The book concludes by studying the action of lightning's electrical and magnetic fields and the lightning current on industrial premises, power transmission lines, underground communications, aircraft and their electrical circuits, and the induction of a dangerous overvoltage. A clear, straightforward, and systematic presentation of complicated material, Lightning Physics and Lightning Protection provides deep insight into the physics of lightning, simple analytical estimates, and a detailed illustration of effects by computer simulation, making this resource essential for those who investigate lightning phenomena and who have to solve practical protection problems.

The Humanities and Human Flourishing series publishes edited volumes that explore the role of human flourishing in the central disciplines of the humanities, and whether and how the humanities can increase human happiness. The contributors to this volume of essays investigate the question: what do literary scholars contribute to social scientific research on human happiness and flourishing? Of all humanities disciplines, none is more resistant to the program of positive psychology or the prevailing discourse of human flourishing than literary studies. The approach taken in this volume of essays is neither to gloss over that antagonism nor to launch a series of blasts against positive psychology and the happiness industry. Rather, the contributors reflect on how their literary research-work to which they are personally committed-might become part of an interdisciplinary conversation about human flourishing. The contributors' areas of research are wide ranging, covering literary aesthetics, book history, digital humanities, and reader reception, as well as the important "inter-disciplines" of gender and sexuality studies, disability studies, and black studies-fields in which issues of stigma and exclusion are paramount, and which have critiqued the discourse of human flourishing for its failure to grapple with structural inequality and human difference. Literary scholars are drawn more readily to the problematic than to the decidable, but by dwelling on the trouble spots in a field of inquiry still largely confined to the sciences, Literary Studies and Human Flourishing provides the groundwork for new and more productive forms of interdisciplinary collaboration and exchange.

Professor Dobbs provides an elegant and clear account of the subject, leading the student from electrostatics through to Maxwell's equations and electromagnetic waves, covering all the material needed by a student taking courses on electricity and magnetism and electromagnetic waves.

Our life is a highly nonlinear process. It starts with birth and ends with death; in between there are a lot of ups and downs. Quite often, we believe that stable and steady situations, probably easy to capture by linearization, are paradisiacal, but already after a short period of everyday routine we usually become bored and seek change, that is, nonlinearities. If we reflect for a while, we notice that our life and our perceptions are mainly determined by nonlinear phenomena, for example, events occurring suddenly and unexpectedly. One may be surprised by how long scientists tried to explain our world by models based on a linear ansatz. Due to the lack of typical nonlinear patterns, although everybody experienced nonlinearities, nobody could classify them and, thus, . study them further. The discoveries of the last few decades have finally provided access to the world of nonlinear phenomena and have initiated a unique inter disciplinary field of research: nonlinear science. In contrast to the general tendency of science to become more branched out and specialized as the result of any progress, nonlinear science has brought together many different disciplines. This has been motivated not only by the immense importance of nonlinearities for science, but also by the wonderful simplicity ohhe concepts. Models like the logistic map can be easily understood by high school students and have brought revolutionary new insights into our scientific under standing."

This booklet presents a study of one-dimensional waves in solids which can be modelled by nonlinear wave equations of different types. The factorization method is the main tool in this analysis. It allows for an exact or at least asymp totic decomposition of the wave(s) under consideration in terms of first order multipliers. Chapter 1 provides a general introduction. It presents some well-known results on characteristics, Riemann invariants, simple waves, etc. The main result of Chap. 1 is Theorem 1.3.2. (Sect. 1.3.2) which establishes the possibility of exact factorization of the nonlinear wave equation EPa(a) 1 EPa _ 0 Ij(l-u- x2 with constant coefficients. This theorem permits one to construct further factor izations of more complicated wave equations which the reader will meet in the following chapters. Chapter 2 is devoted to short wave processes in inhomogeneous media, the main result being the uniform asymptotic factorization of nonlinear wave equa tions with variable coefficients and the description of corresponding single-wave processes without the usual assumption of a small wave amplitude."
