This graduate-level text's primary objective is to demonstrate the expression of the equations of the various branches of mathematical physics in the succinct and elegant form of variational principles (and thereby illuminate their interrelationship). Its related intentions are to show how variational principles may be employed to determine the discrete eigenvalues for stationary state problems and to illustrate how to find the values of quantities (such as the phase shifts) that arise in the theory of scattering. Chapter-by-chapter treatment consists of analytical dynamics; optics, wave mechanics, and quantum mechanics; field equations; eigenvalue problems; and scattering theory. 1966 edition. Bibliography.

Fracture is a major cause of failure in metallic and non-metallic materials and structures. An understanding of the micro- and macro- mechanisms of fracture enables materials scientists to develop materials with high fracture resistance, which in turn helps engineers and designers to ensure the soundness and integrity of structures made from these materials. The International Congress on Fracture is held every four years and is an occasion to take stock of the major achievements in the broad field of fracture, to honour those who have made lasting contributions to this field, and to reflect on the future directions. ICF9 is published in six volumes covering the areas of:-- Failure Analysis, Remaining Life Assessment, Life Extension and Repair- Failure of Multiphase and Non-Metallic Materials- Fatigue of Metallic and Non-Metallic Materials and Structures- Theoretical and Computational Fracture Mechanics and New Directions- Testing and Characterization Methods, and Interfacial Fracture Mechanics- High Strain Rate Fracture and Impact Mechanics.
Written during her twenty-eight-day stay in a small cabin in the remote mountain forests of Northern California, author B. L. Bruce chronicles the daily life of a writer at work. In the wake of her award-winning poetry collection, The Weight of Snow, 28 Days of Solitude moves the focus away from the creative work and toward the often-overlooked creator. Offering insights into her personal thoughts of the craft and its importance in her life before and during her residency, Bruce’s memoir aims to give readers a glimpse into the psyche of a writer.
This exposition is devoted to a consistent treatment of quantization problems, based on appealing to some nontrivial items of functional analysis concerning the theory of linear operators in Hilbert spaces. The authors begin by considering quantization problems in general, emphasizing the nontriviality of consistent operator construction by presenting paradoxes to the naive treatment. It then builds the necessary mathematical background following it by the theory of self-adjoint extensions. By considering several problems such as the one-dimensional Calogero problem, the Aharonov-Bohm problem, the problem of delta-like potentials and relativistic Coulomb problemIt then shows how quantization problems associated with correct definition of observables can be treated consistently for comparatively simple quantum-mechanical systems. In the end, related problems in quantum field theory are briefly introduced. This well-organized text is most suitable for students and post graduates interested in deepening their understanding of mathematical problems in quantum mechanics. However, scientists in mathematical and theoretical physics and mathematicians will also find it useful.
In this case study of police racism and police reform in Australia, the author provides a critical assessment of police initiative in response to the problem of police/minorities relations.
Physical Metallurgy elucidates the microstructure, transformation and properties of metallic materials by means of solid state physics and chemical thermodynamics. Experimental methods of physical metallurgy are also treated. This third edition includes new sections on the permeation of hydrogen in metals, the Landau theory of martensitic transformation, and order hardening and plasticity of intermetallics. Numerous other sections have been brought up to date in the light of new developments (e.g. scanning tunnelling microscopy, CALPHAD-method, diffusion in glasses, DIGM, recrystallisation). New artwork and references have also been added. Professor Haasen's clear and concise coverage of a remarkably wide range of topics will appeal both to physics students at the threshold of their metallurgical careers, and to metallurgists who are interested in the physical foundation of their field.
Has the neuromuscular junction been over-exposed or is it perhaps already a closed book? I asked myself this at a recent International Congress when an American colleague complained that the Journal of Physiology had articles on nothing but the neuromuscular junction, while another colleague asked why I was editing a volume on a subject about which everything was already known. It is worrying to think that these views may be shared by other people. I hope that this volume will convince my two colleagues and other readers that the neuromuscular junction is very much alive and continues to attract the interest of many workers from a variety of fields; strange as it may seem, the synapse between a motor nerve ending and muscle fibre, with its relatively simple architecture, is one of the most inter esting sites in the body-I do hope we have done it justice. The various chapters of this volume present a cross section of knowledge as viewed by a group of 13 individuals, actively engaged in research. Multi-author volumes such as this are frequently criticised on the grounds that chapters or sec tions overlap. I believe that such criticium is only valid where the overlap is repetitious. Where it results in the reader having available discussions of material from differing stand-points, overlap becomes a valuable feature of this type of publication.
Exploring NATO’s post-Cold War determination to support democracy abroad, this book addresses the alliance’s adaptation to the new illiberal backlashes in Eastern Europe, the Western Balkans and Afghanistan after the alleged ‘return of history’. The book engages the question of what has driven NATO to pursue democratisation in face of the significant region-specific challenges and what can explain policy expansion or retrenchment over time. Explaining NATO’s adaptation from the perspective of power dynamics that push for international change and historical experience that informs grand strategy allows wider inferences not only about democratisation as a foreign policy strategy but also about the nature of the transatlantic alliance and its relations with a mostly illiberal environment. Larsen offers a theoretical conception of NATO as a patchwork of one hegemonic and several great power interests that converge or diverge in the formulation of common policy, as opposed to NATO as a community of universal values. This volume will appeal to researchers of transatlantic relations, NATO’s functional and geographical expansion, hegemony and great power politics, democracy promotion, lessons of the past, (Neoclassical) Realism, alliance theory, and the crisis of the liberal world order.
This is the first of two volumes written to celebrate the 40th Anniversary of EFMD. Through an open-ended interview research process, it seeks to explore the perspectives and views of a wide range of experts drawn not only from the European environment but also from the United States and other global players in the management education field.
Derived from the renowned multi-volume International Encyclopaedia of Laws, this practical analysis of the law of contracts in Singapore covers every aspect of the subject – definition and classification of contracts, contractual liability, relation to the law of property, good faith, burden of proof, defects, penalty clauses, arbitration clauses, remedies in case of non-performance, damages, power of attorney, and much more. Lawyers who handle transnational contracts will appreciate the explanation of fundamental differences in terminology, application, and procedure from one legal system to another, as well as the international aspects of contract law. Throughout the book, the treatment emphasizes drafting considerations. An introduction in which contracts are defined and contrasted to torts, quasi-contracts, and property is followed by a discussion of the concepts of ‘consideration’ or ‘cause’ and other underlying principles of the formation of contract. Subsequent chapters cover the doctrines of ‘relative effect’, termination of contract, and remedies for non-performance. The second part of the book, recognizing the need to categorize an agreement as a specific contract in order to determine the rules which apply to it, describes the nature of agency, sale, lease, building contracts, and other types of contract. Facts are presented in such a way that readers who are unfamiliar with specific terms and concepts in varying contexts will fully grasp their meaning and significance. Its succinct yet scholarly nature, as well as the practical quality of the information it provides, make this book a valuable time-saving tool for business and legal professionals alike. Lawyers representing parties with interests in Singapore will welcome this very useful guide, and academics and researchers will appreciate its value in the study of comparative contract law.
Understanding the biotransformations of aromatic compounds and how they metabolize in animals, plants, and microbes, is central to the applications in a wide range of industries, such as the design and testing of natural and synthetic pharmaceuticals, oil refining, the development of agrochemicals, bioremediation, and for use in functional genomics
Covering the general theory of linear stochastic evolution systems with unbounded drift and diffusion operators, this book sureys Ito's second-order parabolic equations and explores filtering problems for processes whose trajectories can be described by them.
In keeping with the spirit of an Advanced Series in the Agricultural Sciences, we have attempted to address herein most of the current research areas being used to characterize, describe and manage salt-affected soils. Because of a certain amount of personal bias inherent in our individual viewpoints and backgrounds, some areas have been accorded more emphasis than others. It has been our goal, however, to provide either detail about, or at least a recent reference to, each major area of current soil salinity research. This information, coupled with what we hope to be a rather logical progression from descriptive material on equilibrium or near-equilibrium soil chemistry, through transport processes, to eventual management practices including some elementary economic decisions, should enable the reader to bridge the gap from introductory soil chemistry or soil physics texts to the basic literature of this area. The text will be perceived by the astute reader as somewhat uneven in its treatment of respective sections. We feel that this is to a certain extent appropriate, for it thus portrays the unevenness of progress to date in the corresponding areas of research. The management of saline and sodic soils remains largely an empirical semi-science or even art, whereas transport phenomena are normally dealt with in a much more theoretical (and also a much more highly mathematical) vein. Equilibrium soil chemistry has historically occupied an intermediate position with respect to its mix of empiricism and theoretical rigor.
Artificial neural networks possess several properties that make them particularly attractive for applications to modelling and control of complex non-linear systems. Among these properties are their universal approximation ability, their parallel network structure and the availability of on- and off-line learning methods for the interconnection weights. However, dynamic models that contain neural network architectures might be highly non-linear and difficult to analyse as a result. Artificial Neural Networks for Modelling and Control of Non-Linear Systems investigates the subject from a system theoretical point of view. However the mathematical theory that is required from the reader is limited to matrix calculus, basic analysis, differential equations and basic linear system theory. No preliminary knowledge of neural networks is explicitly required. The book presents both classical and novel network architectures and learning algorithms for modelling and control. Topics include non-linear system identification, neural optimal control, top-down model based neural control design and stability analysis of neural control systems. A major contribution of this book is to introduce NLq Theory as an extension towards modern control theory, in order to analyze and synthesize non-linear systems that contain linear together with static non-linear operators that satisfy a sector condition: neural state space control systems are an example. Moreover, it turns out that NLq Theory is unifying with respect to many problems arising in neural networks, systems and control. Examples show that complex non-linear systems can be modelled and controlled within NLq theory, including mastering chaos. The didactic flavor of this book makes it suitable for use as a text for a course on Neural Networks. In addition, researchers and designers will find many important new techniques, in particular NLq emTheory, that have applications in control theory, system theory, circuit theory and Time Series Analysis.
This book presents the basic theory and application of the Monte Carlo method to the electronic structure of atoms and molecules. It assumes no previous knowledge of the subject, only a knowledge of molecular quantum mechanics at the first-year graduate level. A working knowledge of traditional ab initio quantum chemistry is helpful, but not essential.Some distinguishing features of this book are:
My interest in ancient Maya agriculture began late in the year of 1971 when William M. Denevan encouraged me to pursue the topic. Our interests had been perked by reports from Joseph W. Ball, JaCk Eaton, and Irwin Rovner of the presence of terrace-like features throughout the Rio Bee region of the soutnern Yucatan Peninsula. Denevan maintained a long-term interest in pre-Hispanic agriculture and population in the New World. Our studies with the emerging Rio Bee research group at the University of Wisconsin led to the conclusion that the then dominant themes of Maya agriculture were in need of reevaluation and that a number of remains of intensive forms of agriculture were likely to be found in the Central Maya lowlands of Mexico, Peten (Guatemala), and Belize, particularly wetland or raised fields in addition to the reported terraces. Our interests were heightened at this time by notification from Alfred Siemens of the finds of wetland fields in the vicinity of the Rio Bee region in the Chetumal, Mexico-northern Belize area.
Hong Kong under British rule was a prime example of exceptionalism in many aspects — economic, political, and even social. It was governed under a colonial structure and yet had enjoyed a large degree of social and economic freedom, as well as fiscal self-sufficiency and autonomy from London. After returning to Chinese rule in 1997, Hong Kong has continued to thrive as a relatively resilient city-state still known for efficiency and effectiveness despite tensions and scepticism about its political future. This book carries decades of academic observations and the author’s personal political experience. It reviews and reflects on the past trajectory of governance and administration, identifying strengths and capabilities as well as constraints and vulnerabilities of Hong Kong as a polity and society, while charting its course of ‘exceptionalism’ within a new context and under changing conditions. As this book concludes, the exceptionalism of Hong Kong not only hinges on institutional arrangements and historical inheritance but also on the statecraft of the administration of the day. ********************************************************* “… This is a text for deep reading, reflection, and deliberation.” – Professor LUI Tai-lok Chair Professor of Hong Kong Studies, Director of the Academy of Hong Kong Studies, Director of the Centre for Greater China Studies, and Former Vice President (Research & Development) at The Education University of Hong Kong “… a gem … whatever your political stand is, you have to admire Professor Cheung’s thorough observations and profound ideas on what made this city tick…” – Mr LAM Woon-kwong Former Secretary for the Civil Service and Secretary for Home Affairs, and Former Convenor of Non-Official Members of the Executive Council (2012–2017) “… a compelling addition to the literature on Hong Kong.” – Professor Darryl S.L.

This book provides a solid overview of the important metallurgical concepts related to the microstructures of irons and steels, and it provides detailed guidelines for the proper metallographic techniques used to reveal, capture, and understand microstructures. This book provides clearly written explanations of important concepts, and step-by-step instructions for equipment selection and use, microscopy techniques, specimen preparation, and etching. Dozens of concise and helpful “metallographic tips” are included in the chapters on laboratory practices and specimen preparation. The book features over 500 representative microstructures, with discussions of how the structures can be altered by heat treatment and other means. A handy index to these images is provided, so the book can also be used as an atlas of iron and steel microstructures.
The genus Verticillium Nees represents one of the world's major fungal pathogens, affecting crop plants mostly in the cool and warm temperate regions, it also occurs in sub-tropical and tropical areas. There are some six species which cause severe wilting in trees, herbaceous plants and plantation crops. Other species are responsible for non-wilt diseases of banana and mushroom, another species infects insects.The monograph provides a comprehensive reference source on Verticillium, enabling research workers to see what has already been achieved and to identify the many new areas of research in which original contributions could be made to further the understanding and control of this important pathogen and the disease it causes.
