The starting point in the formulation of any numerical problem is to take an intuitive idea about the problem in question and to translate it into precise mathematical language. This book provides step-by-step descriptions of how to formulate numerical problems and develops techniques for solving them. A number of engineering case studies motivate the development of efficient algorithms that involve, in some cases, transformation of the problem from its initial formulation into a more tractable form. Five general problem classes are considered: linear systems of equations, non-linear systems of equations, unconstrained optimization, equality-constrained optimization and inequality-constrained optimization. The book contains many worked examples and homework exercises and is suitable for students of engineering or operations research taking courses in optimization. Supplementary material including solutions, lecture slides and appendices are available online at www.cambridge.org/9780521

Multiagent systems combine multiple autonomous entities, each having diverging interests or different information. This overview of the field offers a computer science perspective, but also draws on ideas from game theory, economics, operations research, logic, philosophy and linguistics. It will serve as a reference for researchers in each of these fields, and be used as a text for advanced undergraduate or graduate courses. The authors emphasize foundations to create a broad and rigorous treatment of their subject, with thorough presentations of distributed problem solving, game theory, multiagent communication and learning, social choice, mechanism design, auctions, cooperative game theory, and modal logics of knowledge and belief. For each topic, basic concepts are introduced, examples are given, proofs of key results are offered, and algorithmic considerations are examined. An appendix covers background material in probability theory, classical logic, Markov decision processes and

Algorithmic Aspects of Graph Connectivity is the first comprehensive book on this central notion in graph and network theory, emphasizing its algorithmic aspects. Because of its wide applications in the fields of communication, transportation, and production, graph connectivity has made tremendous algorithmic progress under the influence of the theory of complexity and algorithms in modern computer science. The book contains various definitions of connectivity, including edge-connectivity and vertex-connectivity, and their ramifications, as well as related topics such as flows and cuts. The authors thoroughly discuss new concepts and algorithms that allow for quicker and more efficient computing, such as maximum adjacency ordering of vertices. Covering both basic definitions and advanced topics, this book can be used as a textbook in graduate courses in mathematical sciences, such as discrete mathematics, combinatorics, and operations research, and as a reference book for specialists i

This book presents a mathematical programming approach to the analysis of production frontiers and efficiency measurement. The authors construct a variety of production frontiers, and by measuring distances to them are able to develop a model of efficient producer behaviour and a taxonomy of possible types of departure from efficiency in various environments. Linear programming is used as an analytical and computational technique in order to accomplish this. The approach developed is then applied to modelling producer behaviour. By focusing on the empirical relevance of production frontiers and distances to them, and applying linear programming techniques to artificial data to illustrate the type of information they can generate, this book provides a unique study in applied production analysis. It will be of interest to scholars and students of economics and operations research, and analysts in business and government.

This 2000 book provides an introduction to the nature, occurrence, physical properties, propagation and uses of surfactants in the petroleum industry. It is aimed principally at scientists and engineers who may encounter or use surfactants, whether in process design, petroleum production, or research and development. The primary focus is on applications of the principles of colloid and interface science to surfactant applications in the petroleum industry, and includes attention to practical processes and problems. Applications of surfactants in the petroleum industry are of great practical importance and are also quite diverse, since surfactants may be applied to advantage throughout the petroleum production process: in reservoirs, in oil and gas wells, in surface processing operations, and in environmental, health and safety applications. In each case appropriate knowledge and practices determine the economic and technical successes of the industrial process concerned. The book inclu

The Soviet Union remains a superpower with global security interests and ambitions. The doctrines, practices, and capabilities of its still formidable armed forces are shaping world politics just at the same time that the future of the country that created them is in doubt. This book, first published in 1991, analyses the unprecedented changes, as well as the troubling continuities, that characterized Soviet military thinking during the early 1990s. The authors - a group of leading analysts in the US national security community - confront the range of Soviet military strengths, including intercontinental nuclear power, conventional ground, and naval forces and special operations. They address questions of Soviet weapons research and development, military planning and policy making, and the role of civilian critics on Soviet military objectives. Other chapters explore the Red Army's erosion in Eastern Europe as well as the lessons of Afghanistan.

To perform computer simulation successfully, two rather different sets of skills are required. One of these relates to programming: a simulation program should do what its author intends and do it efficiently. The other is concerned with the collection and analysis of data: statistical tools have to be used in order to obtain with a minimum of effort, accurate and reliable estimates for the desired performance measures. Dr Mitrani covers both of these aspects of the simulation method. The important topics of point and interval estimation, simulation efficiency and the analysis of simulation experiments are discussed in detail. This book, first published in 1982, will be useful to both undergraduate and postgraduate students taking courses on simulation in departments of computer science, operations research and statistics in universities and polytechnics. It will be of benefit also to practitioners in the field.

The partial differential equations that govern scalar and vector fields are the very language used to model a variety of phenomena in solid mechanics, fluid flow, acoustics, heat transfer, electromagnetism and many others. A knowledge of the main equations and of the methods for analyzing them is therefore essential to every working physical scientist and engineer. Andrea Prosperetti draws on many years' research experience to produce a guide to a wide variety of methods, ranging from classical Fourier-type series through to the theory of distributions and basic functional analysis. Theorems are stated precisely and their meaning explained, though proofs are mostly only sketched, with comments and examples being given more prominence. The book structure does not require sequential reading: each chapter is self-contained and users can fashion their own path through the material. Topics are first introduced in the context of applications, and later complemented by a more thorough present

Fishes is a practical introduction to the study of fish remains from archaeological sites, designed for archaeologists and archaezoologists working in the field and in the laboratory. It provides clear guidelines for the identification of remains and how to interpret them. The identification and analysis of fish remains unearthed in archaeological excavations are invaluable factors in the reconstruction of climate, economic strategy, diet and trade. In this manual the authors discuss the importance of fishes in past economies and in archaeological research. They describe methods of extraction, fish anatomy and classification with the aid of numerous line drawings. The book also includes a survey of fishes most likely to be represented in archaeological sites and describes the biology of fishes in order to help archaeozoologists make informed judgements about methods of exploitation, size of fish caught and meat yield. This study is unique in making a realistic assessment of both the po

Beginning with a brief introduction to algorithms and diophantine equations, this volume aims to provide a coherent account of the methods used to find all the solutions to certain diophantine equations, particularly those procedures which have been developed for use on a computer. The study is divided into three parts, the emphasis throughout being on examining approaches with a wide range of applications. The first section considers basic techniques including local methods, sieving, descent arguments and the LLL algorithm. The second section explores problems which can be solved using Baker's theory of linear forms in logarithms. The final section looks at problems associated with curves, mainly focusing on rational and integral points on elliptic curves. Each chapter concludes with a useful set of exercises. A detailed bibliography is included. This book will appeal to graduate students and research workers, with a basic knowledge of number theory, who are interested in solving diop

In this book, Professor Copson gives a rigorous account of the theory of partial differential equations of the first order and of linear partial differential equations of the second order, using the methods of classical analysis. In spite of the advent of computers and the applications of the methods of functional analysis to the theory of partial differential equations, the classical theory retains its relevance in several important respects. Many branches of classical analysing have their origins in the rigourous discussion of problems in applies mathematics and theoretical physics, and the classical treatment of the theory of partial differential equations still provides the best method of treating many physical problems. A knowledge of the classical theory is essential for pure mathematics who intend to undertake research in this field, whatever approach they ultimately adopt. The numerical analyst needs a knowledge of classical theory in order to decide whether a problem has a uni

Knowledge and Ignorance of Self in Platonic Philosophy is the first volume of essays dedicated to the whole question of self-knowledge and its role in Platonic philosophy. It brings together established and rising scholars from every interpretative school of Plato studies, and a variety of texts from across Plato's corpus - including the classic discussions of self-knowledge in the Charmides and Alcibiades I, and dialogues such as the Republic, Theaetetus, and Theages, which are not often enough mined for insights about this crucial philosophical topic. The rich variety of readings and hermeneutical methods (as well as the comprehensive research bibliography included in the volume) allows for an encompassing view of the relevant scholarly debates. The volume is intended to serve as a standard resource for further research on Plato's treatment of self-knowledge, and will highlight the relevance of Plato's thought to contemporary debates on selfhood, self-reflection and subjectivity.

Traditionally, there has been a disconnect between theoretical linguistics and pedagogical teacher training. This book seeks to bridge that gap. Using engaging examples from a wide variety of languages, it provides an innovative overview of linguistic theory and language acquisition research for readers with a background in education and teacher training, and without specialist knowledge of the field. The authors draw on a range of research to ground ideas about grammar pedagogy, presenting the notion of Virtual Grammar as an accessible label for unifying the complexity of linguistics. Organised thematically, the book includes helpful 'Case in point' examples throughout the text, to illustrate specific grammar points, and step-by-step training in linguistic methods, such as how to analyse examples, which educators can apply to their own teaching contexts. Through enriching language teachers' understanding of linguistic features, the book fosters a different perspective on grammar for e

Speaking from and to the growing movement among academics to become involved with 'socially-engaged' work, this volume presents first-person case studies of attempts to fix serious ethical problems in medical practice and research. It highlights the critical difference between the pundit approach to bioethics and the interventional approach - the talkers and the doers - and points to how abused and damaged the doers often end up. Chapters cover a diverse set of topics, including the troubling influence of for-profit businesses on public health policy, the politics of exposing histories of unjust medical research, the challenges of patient rights' work in sexuality and reproduction, collaborations between NGOs and academics, methods for changing entrenched yet harmful medical practices, engaging public policy through educating governmental leaders, and whistleblowing. The trending interest in the interplay of academia and advocacy and the growing importance of 'socially-engaged' work by

This new and completely updated edition gives a detailed description of radiative transfer processes at a level accessible to advanced students. The volume gives the reader a basic understanding of global warming and enhanced levels of harmful ultraviolet radiation caused by ozone depletion. It teaches the basic physics of absorption, scattering and emission processes in turbid media, such as the atmosphere and ocean, using simple semi-classical models. The radiative transfer equation, including multiple scattering, is formulated and solved for several prototype problems, using both simple approximate and accurate numerical methods. In addition, the reader has access to a powerful, state-of-the-art computational code for simulating radiative transfer processes in coupled atmosphere-water systems including snow and ice. This computational code can be regarded as a powerful educational aid, but also as a research tool that can be applied to solve a variety of research problems in environ

This modern and comprehensive guide to long-range dependence and self-similarity starts with rigorous coverage of the basics, then moves on to cover more specialized, up-to-date topics central to current research. These topics concern, but are not limited to, physical models that give rise to long-range dependence and self-similarity; central and non-central limit theorems for long-range dependent series, and the limiting Hermite processes; fractional Brownian motion and its stochastic calculus; several celebrated decompositions of fractional Brownian motion; multidimensional models for long-range dependence and self-similarity; and maximum likelihood estimation methods for long-range dependent time series. Designed for graduate students and researchers, each chapter of the book is supplemented by numerous exercises, some designed to test the reader's understanding, while others invite the reader to consider some of the open research problems in the field today.

Since their inception, the Perspectives in Logic and Lecture Notes in Logic series have published seminal works by leading logicians. Many of the original books in the series have been unavailable for years, but they are now in print once again. Stability theory was introduced and matured in the 1960s and 1970s. Today stability theory influences and is influenced by number theory, algebraic group theory, Riemann surfaces, and representation theory of modules. There is little model theory today that does not involve the methods of stability theory. In this volume, the fourth publication in the Perspectives in Logic series, Steven Buechler bridges the gap between a first-year graduate logic course and research papers in stability theory. The book prepares the student for research in any of today's branches of stability theory, and gives an introduction to classification theory with an exposition of Morley's Categoricity Theorem.

Questions about modular representation theory of finite groups can often be reduced to elementary abelian subgroups. This is the first book to offer a detailed study of the representation theory of elementary abelian groups, bringing together information from many papers and journals, as well as unpublished research. Special attention is given to recent work on modules of constant Jordan type, and the methods involve producing and examining vector bundles on projective space and their Chern classes. Extensive background material is provided, which will help the reader to understand vector bundles and their Chern classes from an algebraic point of view, and to apply this to modular representation theory of elementary abelian groups. The final section, addressing problems and directions for future research, will also help to stimulate further developments in the subject. With no similar books on the market, this will be an invaluable resource for graduate students and researchers working

The dwarf and mouse lemurs of Madagascar are two very species-rich lemur genera, yet there is a relative paucity of information on this primate family in published literature. In this first ever treatment of the Cheirogaleidae, international experts are brought together to review and integrate our current knowledge of the behaviour, physiology, ecology, genetics and biogeography of these species. A wide range of direct and indirect research methods that are currently used to study these cryptic nocturnal solitary foragers are described. By uniting often disparate research on captive and free-ranging taxa and synthesising recent methodological advances, this book provides new insights that will encourage further studies of this fascinating primate family. This synthesis will provide an incentive for more integrative studies of the Cheirogaleidae in captivity and in the wild, enabling the impacts of deforestation and other factors to be identified and directions for future conservation e

The history of the English language is a vast and diverse area of research. In this volume, a team of leading historians of English come together to analyse 'real' language, drawing on corpus data to shed new light on long-established issues and debates in the field. Combining synchronic and diachronic analysis, the chapters address the major issues in corpus linguistics – methodological, theoretical and applied – and place special focus on the use of electronic resources in the research of English and the wider field of digital humanities. Topics covered include polemical articles on the optimal use of corpus linguistic methods, macro-level patterns of text and discourse organisation, and micro-features such as interjections and hesitators. Covering Englishes from the past and present, this book is designed specifically for graduate students and researchers working in fields of corpus linguistics, the history of the English language, and historical linguistics.

Deliberative democracy is now an influential approach to the study of democracy and political behaviour. Its key proposition is that, in politics, it is not only power that counts, but good discussions and arguments too. This book examines the interplay between the normative and empirical aspects of the deliberative model of democracy. Jürg Steiner presents the main normative controversies in the literature on deliberation, including self-interest, civility and truthfulness. He then summarizes the empirical literature on deliberation and proposes methods by which the level of deliberation can be measured rather than just assumed. Steiner's empirical research is based in the work of various research groups, including experiments with ordinary citizens in the deeply divided societies of Colombia, Bosnia-Herzegovina and Belgium, as well as Finland and the European Union. Steiner draws normative implications from a combination of both normative controversies and empirical findings.

This book was first published in 1985. For those working in molecular biology, this book describes techniques in plant genetic research and the practical application of genetic engineering to important crop plants such as the potato. The various chapters detail methods used for the genetic modification of plants, including protoplast fusion and the use of Agrobacterium and viruses as vectors for plant genes. The types of agricultural and industrial processes that will be improved by these technologies are indicated throughout the book. The contributors to this volume have prepared a comprehensive and pertinent bibliography that is a key to the literature. Their scientific reports will enlighten advanced students, research workers and technicians in botany, biochemistry and biotechnology. All scientists in plant molecular biology, genetics, biochemistry and agriculture should find this book a valuable aid in their understanding of current techniques, principles and applications in plant

This two-volume work, co-authored by Edmund Gurney (1847–1888), Frederic W. H. Myers (1843–1901) and Frank Podmore (1856–1910), all leading members of the Society for Psychical Research, was first published in 1886. It documents over 700 case studies of ghost-seeing, and aimed to revolutionise thinking about ghosts by proposing a theory that explained ghost-seeing through the idea of telepathy. Volume 1 includes an introduction by Myers and an explanation of the analytical methods used in the study. It then focuses on hypnotism, the telepathic transference of ideas, mental pictures and emotional impressions, dreams, and hallucinations, and contains an impressive essay on the history of witchcraft. This pioneering study is an indispensable source for the history of psychical research. It provides detailed insights into the Victorian fascination with the occult and the supernatural, and is still the most extensive collection of ghost-seeing accounts available.

Originally published in 2005, this unique resource presents 27 easy-to-follow laboratory exercises for use in student practical classes in developmental biology. These experiments provide key insights into developmental questions, and many of them are described by the leaders in the field who carried out the original research. This book intends to bridge the gap between experimental work and the laboratory classes taken at the undergraduate and post-graduate levels. All chapters follow the same format, taking the students from materials and methods, through results and discussion, so that they learn the underlying rationale and analysis employed in the research. The book will be an invaluable resource for graduate students and instructors teaching practical developmental biology courses. Chapters include teaching concepts, discussion of the degree of difficulty of each experiment, potential sources of failure, as well as the time required for each experiment to be carried out in a clas

The study of permutation patterns is a thriving area of combinatorics that relates to many other areas of mathematics, including graph theory, enumerative combinatorics, model theory, the theory of automata and languages, and bioinformatics. Arising from the Fifth International Conference on Permutation Patterns, held in St Andrews in June 2007, this volume contains a mixture of survey and research articles by leading experts, and includes the two invited speakers, Martin Klazar and Mike Atkinson. Together, the collected articles cover all the significant strands of current research: structural methods and simple patterns, generalisations of patterns, various enumerative aspects, machines and networks, packing, and more. Specialists in this area and other researchers in combinatorics and related fields will find much of interest in this book. In addition, the volume provides plenty of material accessible to advanced undergraduates and is a suitable reference for projects and dissertati

Discover what you can do with R! Introducing the R system, covering standard regression methods, then tackling more advanced topics, this book guides users through the practical, powerful tools that the R system provides. The emphasis is on hands-on analysis, graphical display, and interpretation of data. The many worked examples, from real-world research, are accompanied by commentary on what is done and why. The companion website has code and datasets, allowing readers to reproduce all analyses, along with solutions to selected exercises and updates. Assuming basic statistical knowledge and some experience with data analysis (but not R), the book is ideal for research scientists, final-year undergraduate or graduate-level students of applied statistics, and practising statisticians. It is both for learning and for reference. This third edition expands upon topics such as Bayesian inference for regression, errors in variables, generalized linear mixed models, and random forests.

Methadone has been used successfully as a substitution agent for heroin dependency for more than 30 years. As a result of its success, other effective methods of treatment have been neglected. Established as a key text on all treatment options for drug misusers, Community Treatment of Drug Misuse: More Than Methadone has been highly praised for its practical orientation based on a solid research background. For the second edition, all the main evidence-based and more pragmatic treatment approaches are reviewed, not only in the management of opiate dependence, but across the range of drugs. It focuses extensively on developments in the last few years as a result of policy initiatives and research findings, including coverage of buprenorphine treatment, the systematic treatment of cocaine abuse and work with special patient groups. This is of direct relevance to medical as well as non-medical practitioners undertaking clinical work in the addictions.
