In this book, the issues regarding the theory of optics and quantum optics of spherical multilayered systems are studied. In such systems the spatial scale of layers becomes comparable with the wavelength of radiation, which complicates the analysis of important quantities such as reflectivity and transmission. Often, a large amount of time is spent on performing numerical calculations and simulation to elucidate the behavior of such electromagnetic properties. The author has written down the calculation details of important properties of multilayered microspheres in a more comprehensive manner, so that undergraduates and practitioners can follow them freely.From a skill-oriented point of view the book covers the following: electrodynamics of multilayered environments in the spherical geometry; methods of calculating both reflection and transmission coefficients from an alternating stack; calculations of eigenfrequencies and quality factors of electromagnetic oscillations; radial distribution of the electromagnetic field in a spherical cavity; computer methods of calculations with C++ as basic languages and construction of the graphic user interface (GUI); the object-oriented approach as a basis of the modern methods of calculation.

Engineering represents an ordered activity of creative design and inventive manufacture of ingenious devices. Its practitioners have thereby stimulated individuals, enlivened communities, enriched civilizations, and contributed to the shaping of cultures.The authors of this innovative text develop a systematic framework for engineering in time, making extensive use of adaptive heterogeneous progressions. When combined with considerations of feedback, feedforward, recursion, and branching, an evolving and comprehensive characterization of engineering becomes evident. It is in this blending of chronology, emerging theory, and professional practice that engineering finds its foundational role in innovative design, device reliability, intellectual property, technology risks, public safety, professional ethics, material accounting, and other recurring themes relevant to contemporary engineering. Engineering clearly emerges as a complex and increasingly important profession.The authors introduce concepts and methods — including a critical definition of engineering -and selectively adapt symbolic-mathematical relations. The technical level of analysis is suitable for the undergraduate curriculum commonly encountered in colleges of engineering.

This book provides a summary of the various aspects of corneal transplantation — the clinical, experimental (including multimedia display of the surgical techniques), immunological, therapeutic and prosthetic components — in one volume. The interested specialist in one field can thus have access to information from the other fields and develop a broad concept of the challenges to be faced in achieving the ultimate goal, i.e. an optically clear, visually satisfactory, functioning corneal graft which is tolerated in the long term without the need for systemic immunosuppression. A second purpose of the book is to provide information regarding current immunological concepts of the process of corneal graft rejection. In particular, recent work in the fields of innate versus adaptive immunity, novel therapeutics and corneal xenografts is presented.

This book presents a practical guide to the analysis of materials and includes a thorough description of the underlying theories and instrumental aberrations caused by real experiments. The main emphasis concerns the analysis of thin films and multilayers, primarily semiconductors, although the techniques are very general. Semiconductors can be very perfect composite crystals and therefore their study can lead to the largest volume of information, since X-ray scattering can assess the deviation from perfection.The description is intentionally conceptual so that the reader can grasp the real processes involved. In this way the analysis becomes significantly easier, making the reader aware of misleading artifacts and assisting in the determination of a more complete and reliable analysis. The theory of scattering is very important and is covered in such a way that the assumptions are clear. Greatest emphasis is placed on the dynamical diffraction theory including new developments extending its applicability to reciprocal space mapping and modelling samples with relaxed and distorted interfaces.A practical guide to the measurement of diffraction patterns, including the smearing effects introduced to the measurement, is also presented.

This book describes a search for geological evidence of meteorite impact structures in Britain. The statistics of impact structures indicate that Britain should have Phanerozoic impact structures up to tens of kilometres in diameter. A constant theme is the importance of atmospheric break-up of small asteroids and comets. These fragmenting bodies produce anomalously shallow craters with low rims and central peaks; three British structures of this type are identified.Analysis of fireball statistics implies that damaging fireball explosions occur over the British Isles on a time-scale of decades. On a time-scale of millennia, however, more damage is done by Atlantic impact tsunami.

The discovery of superconductivity at 30 K by Bednorz and Müller in 1986 ignited an explosion of interest in high temperature superconductivity. The initial development rapidly evolved into an intensive worldwide research effort — which still persists after more than a decade — to understand the phenomenon of cuprate superconductivity, to search for ways to raise the transition temperature and to produce materials which have the potential for technological applications.During the past decade of research on this subject, significant progress has been made on both the fundamental science and technological application fronts. A great deal of experimental data is now available on the cuprates, and various properties have been well characterized using high quality single crystals and thin films. Despite this enormous research effort, however, the underlying mechanisms responsible for superconductivity in the cuprates are still open to question.This book offers an understanding from the phase transition point of view, surveys and identifies thermal and quantum fluctuation effects, identifies material-independent universal properties and provides constraints for the microscopic description of the various phenomena. The text is presented in a format suitable for use in a graduate level course.

The fact that the World Health Organization has declared tuberculosis a “global emergency” indicates the serious inadequacy of the ways in which the control methods at our disposal are used. Several books on tuberculosis have been published in recent years, but none have taken a deep and detailed look at the “holistic” aspects of global tuberculosis control, even though international agencies are increasingly aware of the importance of the numerous factors other than the design and efficacy of therapeutic drug regimens. This unique book fills that gap. Although it deals specifically with tuberculosis, the principles outlined and discussed are relevant to many other areas of global medicine, including the ever-growing problem of HIV/AIDS.The book is aimed principally at those involved in the design, establishment and management of disease control programmes at international, national and local levels, and also at a more general readership of epidemiologists, public health officers, community psychologists, and others interested in understanding the human dimension of disease control.

As the first in the “Clinical Talk” series, the philosophy of this book is to have a set of question-based sections to help a final-year medical student prepare for exams. These sections include multiple choice questions (MCQs), extended matching questions (EMQs) and case studies. The idea is to have not just a “test yourself” book, but one which students can work through as a learning exercise as well as for revision purposes. For that reason, the answers and explanations provided here are just as important as the questions themselves.Stansby and Goldberg have structured this book such that it complements one of their bestselling textbooks, Surgical Talk: Revision in Surgery.

This textbook introduces the tools and language of modern geometric mechanics to advanced undergraduate and beginning graduate students in mathematics, physics, and engineering. It treats the dynamics of rotating, spinning and rolling rigid bodies from a geometric viewpoint, by formulating their solutions as coadjoint motions generated by Lie groups. The only prerequisites are linear algebra, multivariable calculus and some familiarity with Euler-Lagrange variational principles and canonical Poisson brackets in classical mechanics at the beginning undergraduate level.Variational calculus on tangent spaces of Lie groups is explained in the context of familiar concrete examples. Through these examples, the student develops skills in performing computational manipulations, starting from vectors and matrices, working through the theory of quaternions to understand rotations, and then transferring these skills to the computation of more abstract adjoint and coadjoint motions, Lie-Poisson Hamiltonian formulations, momentum maps and finally dynamics with nonholonomic constraints.The 120 Exercises and 55 Worked Answers help the student to grasp the essential aspects of the subject, and to develop proficiency in using the powerful methods of geometric mechanics. In addition, all theorems are stated and proved explicitly. The book's many examples and worked exercises make it ideal for both classroom use and self-study.

Britain was the first country to exploit atomic energy on a large scale, and at its peak in the mid-1960s, it had generated more electricity from nuclear power than the rest of the world combined.The civil atomic energy programme grew out of the military programme which produced plutonium for atomic weapons. In 1956, Calder Hall power station was opened by the Queen. The very next year, one of the early Windscale reactors caught fire and the world's first major nuclear accident occurred.The civil programme ran into further difficulty in the mid-1960s and as a consequence of procrastination in the decision-making process, the programme lost momentum and effectively died. No nuclear power stations have been built since Sizewell B in the late 1980s.This book presents a study of Government papers that have recently become available in the public domain. For the first time in history, the research reactor programme is presented in detail, along with a study of the decision-making by the Government, the Atomic Energy Authority (AEA), and the Central Electricity Board (CEGB). This book is aimed at both specialists in nuclear power and the interested public as a technical history on the development and ultimate failure of the British atomic energy programme.

Engineering structures considered include bars, columns, struts, tubes, vessels, beams, springs and frames. The loadings imposed upon them are, typically, tension, compression and shear, bending, torsion and pressure, separately and in combination. The mechanics of such structures examine the manner in which they each bear their respective loading in a safe predictable way. This aids design considerations upon choice of material and its physical shape when seeking, say, a safe design with low weight.The presentation of chapters is intended to guide the reader from a basic to more advanced understanding of common engineering structures. Thus, the consideration of stress and strain under elastic and plastic conditions is required for a full understanding of a structure that may bend, twist and buckle as it is deflected by its loading. The approach adopted is to intersperse theory with examples and exercises that emphasise practical application. Standard analytical techniques including stress transformation, energy methods and yield criteria precede a final chapter on finite element analysis.Worked examples and exercises have been devised and compiled by the author to support the topics within each chapter. Some have been derived, with a conversion to SI units, from past examination papers set by institutions with which the author has been associated, namely: Brunel, Kingston and Surrey Universities and the Council of Engineering Institutions.The contents should serve most courses in mechanical, civil, aeronautical and materials engineering.

Communication networks and computer systems research is entering a new phase in which many of the established models and techniques of the last twenty years are being challenged. The research community is continuing to free itself from past intellectual constraints so that it may fully exploit the convergence of computing and communications. Evaluating the performance of emerging communications and computer systems constitutes a huge challenge. Thus, current research provides a set of heterogeneous tools and techniques embracing the uncertainties of time and space varying environments when the requests for diverse services are made in real time, and with very different quality of service expectations.These novel techniques will lead to fast and economic service deployment and effective dynamic resource management, and hence to new business strategies and infrastructures that will facilitate the emergence of future services and applications.This volume contains contributions and presentations made by leading international researchers at a workshop which was held in April 2004 to honour Professor Erol Gelenbe on the occasion of his inaugural lecture as the Dennis Gabor Chair at Imperial College London.

The last decade has seen major advances in our understanding of the basic scientific principles that underpin clinical neurology. Many of these advances have already had a major impact on routine clinical practice, and this is likely to continue in the future. Although this makes it an exciting time to practice neurology, it also presents new challenges. How can established general neurologists keep up-to-date with clinically relevant scientific advances, and how can the specialist remain competent outside his own field? What should trainee neurologists learn to prepare themselves for the future career?Written by experts in the field, this timely book presents the scientific principles behind neurology. It aims to take the reader from the human genome, through gene expression, to molecular and cellular pathology, and subsequently to contemporary clinical investigations and clinical trials. Each contribution includes a discussion about the future of the field and highlights areas of potential growth and their relevance to routine clinical practice over the next decade. The succinctly written chapters will be easily accessible to both neurologists and trainees who have no expertise in the area.Many of the chapters are co-written by a clinician and a basic scientist, and each has been subject to peer review — both by experts in the field and a “jobbing” general neurologist. This has ensured that the contributions reflect contemporary scientific thinking which is presented in a way that is easy to digest. The book includes generous use of diagrams to help explain difficult concepts, a glossary explaining the terminology, and provides information on links to web-based resources for further information.

This book is based on lectures presented over many years to second and third year mathematics students in the Mathematics Departments at Bedford College, London, and King's College, London, as part of the BSc. and MSci. program. Its aim is to provide a gentle yet rigorous first course on complex analysis.Metric space aspects of the complex plane are discussed in detail, making this text an excellent introduction to metric space theory. The complex exponential and trigonometric functions are defined from first principles and great care is taken to derive their familiar properties. In particular, the appearance of π, in this context, is carefully explained.The central results of the subject, such as Cauchy's Theorem and its immediate corollaries, as well as the theory of singularities and the Residue Theorem are carefully treated while avoiding overly complicated generality. Throughout, the theory is illustrated by examples.A number of relevant results from real analysis are collected, complete with proofs, in an appendix.The approach in this book attempts to soften the impact for the student who may feel less than completely comfortable with the logical but often overly concise presentation of mathematical analysis elsewhere.

An essential graduate level text on the asymptotic analysis of ordinary differential equations, this book covers all the important methods including dominant balance, the use of divergent asymptotic series, phase integral methods, asymptotic evaluation of integrals, and boundary layer analysis. The construction of integral solutions and the use of analytic continuation are used in conjunction with the asymptotic analysis, to show the interrelatedness of these methods. Some of the functions of classical analysis are used as examples, to provide an introduction to their analytic and asymptotic properties, and to give derivations of some of the important identities satisfied by them. There is no attempt to give a complete presentation of all these functions. The emphasis is on the various techniques of analysis: obtaining asymptotic limits, connecting different asymptotic solutions, and obtaining integral representation.

Building on the material learned by students in their first few years of study, this book presents an advanced level course on statistical and thermal physics. It begins with a review of the formal structure of statistical mechanics and thermodynamics considered from a unified viewpoint. After a brief revision of non-interacting systems, emphasis is laid on interacting systems. First, weakly interacting systems are considered, where the interest is in seeing how such interactions cause small deviations from the non-interacting case. Second, systems are examined where interactions lead to drastic changes, namely phase transitions. A number of specific examples are given, and these are unified within the Landau theory of phase transitions. The final chapter of the book looks at non-equilibrium systems and the way these evolve towards equilibrium. Here, fluctuations play a vital role, as is formalized in the Fluctuation-Dissipation theorem.

Atomic clusters are the bridge between molecules and the bulk matter. Following two key experiments — the observation of electronic shells in metallic clusters and the discovery of the C60 fullerence — the field of atomic clusters has experienced a rapid growth, and is now considered a mature field. The electrons of the cluster are confined to a small volume, hence, quantum effects are manifested on many properties of the clusters. Another interesting feature is that the properties often change in a non-smooth way as the number of atoms in the cluster increases. This book provides an updated overview of the field, and presents a detailed description of the structure and electronic properties of different types of clusters: Van der Waals clusters, metallic clusters, clusters of ionic materials and network clusters. The assembling of clusters is also considered, since specially stable clusters are expected to play a role in the future design and synthesis of new materials.

The book presents exact results for one-dimensional models (including quantum spin models) of strongly correlated electrons in a comprehensive and concise manner. It incorporates important results related to magnetic and hybridization impurities in electron hosts and contains exact original results for disordered ensembles of impurities in interacting systems. These models describe a number of real low-dimensional electron systems that are widely used in nanophysics and microelectronics.An important method of modern theoretical and mathematical physics — the Bethe's Ansatz (BA) — is introduced to readers. This book presents different forms of the BA for periodic and open quantum chains. Other forms dealt with are the co-ordinate BA, thermodynamic BA, nested BA, algebraic BA, and thermal BA. The book also contains a compact description of other theoretical methods such as scaling, conformal field theory, Abelian and non-Abelian bosonizations.The book is suitable for use as a textbook by graduate students in non-perturbative methods of low-dimensional quantum many-body theory. It will also be a useful source of reference for qualified physicists, as well as non-experts in low-dimensional physics, as it explores material necessary for further studies in the fields of exactly solvable quantum models and low-dimensional correlated electron systems.

This book provides an introduction to representations of both finite and compact groups. The proofs of the basic results are given for the finite case, but are so phrased as to hold without change for compact topological groups with an invariant integral replacing the sum over the group elements as an averaging tool. Among the topics covered are the relation between representations and characters, the construction of irreducible representations, induced representations and Frobenius reciprocity. Special emphasis is given to exterior powers, with the symmetric group Sn as an illustrative example. The book concludes with a chapter comparing the representations of the finite group SL2(p) and the non-compact Lie group SL2(P).

Ultrafiltration is a pressure-driven, membrane-based separation process, which is used for a broad variety of applications, ranging from the processing of biological macromolecules to wastewater treatment. It has significant advantages over competing separation technologies. Food and biotechnological applications account for nearly 40% of the current total usage of ultrafiltration membranes. Protein bioseparation is an important component of this application segment. Ultrafiltration is used for protein concentration, desalting, clarification and fractionation (i.e. protein-protein separation). Concentration, desalting and clarification are technologically less demanding and have been in used in the bioprocess industry for some time. Protein fractionation, on the other hand, is a challenging proposition and is definitely a more recent development. This book focuses primarily on protein fractionation.

Colossal magnetoresistance materials, to which manganites and conventional ferromagnetic semiconductors belong, draw great attention because of their intriguing physical properties and the excellent prospects for their practical applications in electronic devices. In addition, magnetic semiconductors are basic materials for high-temperature conductors, and it is impossible to construct a theory of the latter without elucidating properties of the former.This book presents theoretical and experimental results on manganites and conventional magnetic semiconductors, with emphasis on the former. It is addressed mainly to researchers dealing with manganites or high-temperature superconductors, but is also useful for undergraduate and graduate students.
