Mathematics of Discrete Structures for Computer Science

The idea of forecasting the weather by calculation was first dreamt of by Lewis Fry Richardson. He set out in this book a detailed algorithm for systematic numerical weather prediction. The method of computing atmospheric changes, which he mapped out in great detail in this book, is essentially the method used today. He was greatly ahead of his time because, before his ideas could bear fruit, advances in four critical areas were needed: better understanding of the dynamics of the atmosphere; stable computational algorithms to integrate the equations; regular observations of the free atmosphere; and powerful automatic computer equipment. Over the ensuing years, progress in numerical weather prediction has been dramatic. Weather prediction and climate modelling have now reached a high level of sophistication, and are witness to the influence of Richardson's ideas. This new edition contains a new foreword by Peter Lynch that sets the original book in context.

Although few dispute the computer's place as a pivotal twentieth century artefact, little agreement has emerged over whether the changes it has precipitated are generally positive or negative in nature, or whether we should be contemplating our future association with the computer more with enthusiasm or trepidation. Specifically with regard to the relationship between women and computers, a diverse body of commentary has embraced the views of those who have found grounds for expressing pessimism about this association and those who have favoured a more optimistic assessment of the current situation and its probable future development. This book undertakes a thorough evaluation of the legitimacy and predictive power of the optimistic commentary. Using a large body of original qualitative data, it interrogates the bases of what it identifies as three waves of optimism and in doing so provides answers to some of the key questions asked in this field today.

Equal parts medical mystery, cultural criticism, and rallying cry, writer Elissa Bassist shares her journey to reclaim her authentic voice in a culture that doesn't listen to women.Between 2016 and 2018, Elissa Bassist saw over twenty medical professionals for a variety of mysterious ailments. Bassist had what millions of American women had: pain that didn’t make sense to doctors, a body that didn’t make sense to science, a psyche that didn’t make sense to mankind. But then an acupuncturist suggested some of her physical pain could be caged fury finding expression, and that treating her voice would treat the problem. It did.Growing up, Bassist's family, boyfriends, school, work, and television had the same expectation for a woman’s voice: less is more. She was called dramatic and insane for speaking her mind; she was accused of overreacting and playing victim for having unexplained physical pain; she was ignored or rebuked like women throughout history for using her voice “inappropriat

Seismic Ray Theory presents a comprehensive treatment of the seismic ray method. This method plays an important role in seismology, seismic exploration, and in the interpretation of seismic measurements. Many concepts which extend the possibilities and increase the efficiency of the seismic ray method are included. The book has a tutorial character: derivations start with a relatively simple problem, in which the main ideas are easier to explain, and then advance to more complex problems. Most of the derived equations in the book are expressed in algorithmic form and may be used directly for computer programming. This book will prove to be an invaluable advanced textbook and reference volume in all academic institutions in which seismology is taught or researched. It will also be an invaluable resource in the research and exploration departments of the petroleum industry and in geological surveys.

While transnational conglomerates consolidate their control of the global mediascape, local communities struggle to create democratic media systems. This groundbreaking study of community media, first published in 2005, combines original research with comparative and theoretical analysis in an engaging and accessible style. Kevin Howley explores the different ways in which local communities come to make use of various technologies such as radio, television, print and computer networks for purposes of community communication and considers the ways these technologies shape, and are shaped by, the everyday lived experience of local populations. He also addresses broader theoretical and philosophical issues surrounding the relationship between communication and community, media systems and the public sphere. Case studies illustrate the pivotal role community media play in promoting cultural production and communicative democracy within and between local communities. This book will make a s

The world's coastlines, dividing land from sea, are geological environments that are unique in their composition and the physical processes affecting them. At the dynamically active intersection of land and the oceans, humans have been building structures throughout history. Initially used for naval and commercial purposes, more recently recreation and tourism have increased activity in the coastal zone dramatically. Shoreline development is now causing a significant conflict with natural coastal processes. This text on coastal engineering will help the reader understand these coastal processes and develop strategies to cope effectively with shoreline erosion. The book is organized in four parts: (1) an overview of coastal engineering, using case studies to illustrate problems; (2) hydrodynamics of the coastal zone, reviewing storm surges, water waves, and low frequency motions within the nearshore and surf zone; (3) coastal responses including equilibrium beach profiles and sediment

Burnout is a major psychological and physical health-related problem for workers in all fields, but especially for those in the fast-paced and rapidly changing world of healthcare. Burnout has severe consequences for patients, including medical error, and is a leading contributing cause of depression and suicide among healthcare workers. Organizational science is just beginning to be applied in earnest to physician burnout and patient safety, and holds several potential keys to addressing these concerns. The Burned Out Physician is for two groups: healthcare workers (especially physicians) and patients. Physicians will use this book to get an accurate picture of what they are experiencing and how to change it, and patients will use this book to see what their healthcare providers are experiencing and learn how to help and/or protect themselves. The volume includes a checklist of burnout symptoms, and crucially a list of solutions as part of an active effort to solve the burnout crisis.

Humans have been on the move for most of history. Even after the great urban advancement lured people into the great cities of Uruk, Babylon, Rome and Chang'an, most of us continued to live lightly on the move and outside the pages of history. But recent discoveries have revealed another story .. . Wandering people built the first great stone monuments, such as the one at Goebekli Tepe, seven thousand years before the pyramids.They tamed the horse, fashioned the composite bow, fought with the Greeks and hastened the end of the Roman Empire. They had a love of poetry and storytelling, a fascination for artistry and science, and a respect for the natural world rooted in reliance and their belief. Embracing multiculturalism, their need for free movement and open markets brought a glorious cultural flourishing to Eurasia, enabling the Renaissance and changing the human story.Reconnecting with our deepest mythology, our unrecorded antiquity and our natural environment, Nomads is the untold

Galois Theory, the theory of polynomial equations and their solutions, is one of the most fascinating and beautiful subjects of pure mathematics. Using group theory and field theory, it provides a complete answer to the problem of the solubility of polynomial equations by radicals: that is, determining when and how a polynomial equation can be solved by repeatedly extracting roots using elementary algebraic operations. This textbook contains a fully detailed account of Galois Theory and the algebra that it needs and is suitable both for those following a course of lectures and the independent reader (who is assumed to have no previous knowledge of Galois Theory). The second edition has been significantly revised and re-ordered; the first part develops the basic algebra that is needed, and the second a comprehensive account of Galois Theory. There are applications to ruler-and- compass constructions, and to the solution of classical mathematical problems of ancient times. There are new

Stochastic games have an element of chance: the state of the next round is determined probabilistically depending upon players' actions and the current state. Successful players need to balance the need for short-term payoffs while ensuring future opportunities remain high. The various techniques needed to analyze these often highly non-trivial games are a showcase of attractive mathematics, including methods from probability, differential equations, algebra, and combinatorics. This book presents a course on the theory of stochastic games going from the basics through to topics of modern research, focusing on conceptual clarity over complete generality. Each of its chapters introduces a new mathematical tool – including contracting mappings, semi-algebraic sets, infinite orbits, and Ramsey's theorem, among others – before discussing the game-theoretic results they can be used to obtain. The author assumes no more than a basic undergraduate curriculum and illustrates the theory with num

Gravitational lensing is a consequence of general relativity, where the gravitational force due to a massive object bends the paths of light originating from distant objects lying behind it. Using very little general relativity and no higher level mathematics, this text presents the basics of gravitational lensing, focusing on the equations needed to understand the phenomena. It then applies them to a diverse set of topics, including multiply imaged objects, time delays, extrasolar planets, microlensing, cluster masses, galaxy shape measurements, cosmic shear, and lensing of the cosmic microwave background. This approach allows undergraduate students and others to get quickly up to speed on the basics and the important issues. The text will be especially relevant as large surveys such as LSST and Euclid begin to dominate the astronomical landscape. Designed for a one semester course, it is accessible to anyone with two years of undergraduate physics background.

Mechanism design is an analytical framework for thinking clearly and carefully about what exactly a given institution can achieve when the information necessary to make decisions is dispersed and privately held. This analysis provides an account of the underlying mathematics of mechanism design based on linear programming. Three advantages characterize the approach. The first is simplicity: arguments based on linear programming are both elementary and transparent. The second is unity: the machinery of linear programming provides a way to unify results from disparate areas of mechanism design. The third is reach: the technique offers the ability to solve problems that appear to be beyond solutions offered by traditional methods. No claim is made that the approach advocated should supplant traditional mathematical machinery. Rather, the approach represents an addition to the tools of the economic theorist who proposes to understand economic phenomena through the lens of mechanism design.

The world around us, natural or man-made, is built and held together by solid materials. Understanding their behaviour is the task of solid mechanics, which is in turn applied to many areas, from earthquake mechanics to industry, construction to biomechanics. The variety of materials (metals, rocks, glasses, sand, flesh and bone) and their properties (porosity, viscosity, elasticity, plasticity) is reflected by the concepts and techniques needed to understand them: a rich mixture of mathematics, physics and experiment. These are all combined in this unique book, based on years of experience in research and teaching. Starting from the simplest situations, models of increasing sophistication are derived and applied. The emphasis is on problem-solving and building intuition, rather than a technical presentation of theory. The text is complemented by over 100 carefully-chosen exercises, making this an ideal companion for students taking advanced courses, or those undertaking research in th

Geometry provides a whole range of views on the universe, serving as the inspiration, technical toolkit and ultimate goal for many branches of mathematics and physics. This book introduces the ideas of geometry, and includes a generous supply of simple explanations and examples. The treatment emphasises coordinate systems and the coordinate changes that generate symmetries. The discussion moves from Euclidean to non-Euclidean geometries, including spherical and hyperbolic geometry, and then on to affine and projective linear geometries. Group theory is introduced to treat geometric symmetries, leading to the unification of geometry and group theory in the Erlangen program. An introduction to basic topology follows, with the Möbius strip, the Klein bottle and the surface with g handles exemplifying quotient topologies and the homeomorphism problem. Topology combines with group theory to yield the geometry of transformation groups,having applications to relativity theory and quantum mech

This book is an elementary introduction to the geometrical methods and notions used in special and general relativity. Particular emphasis is placed on the ideas concerned with the structure of spacetime and those which play a role in the Penrose–Hawking singularity theorems. Indeed, the author's prime purpose is to give a rigorous proof of the simplest of these theorems yet one which is representative of the whole. No previous exposure either to relativity theory or differential geometry is required to the reader, as necessary concepts are developed when needed, though in order to keep the presentation reasonably accessible, some restrictions are imposed on the types of space considered. Each chapter is liberally supplied with exercises and examples. The book will therefore be attractive to senior undergraduate and first year graduate students of mathematics and physics for independent study or courses preparatory to more advanced works.

He describes examples of planning and safety failures, provides forecasts of future disasters and proposes solutions for hazard mitigation. The book shows how billions of dollars and countless lives could be saved by adopting longer-term thinking for infrastructure planning and building, and argues that better communication is vital in reducing

Frank Podmore (1856–1910) published Modern Spiritualism in two volumes in 1902. It was the first comprehensive history of the Spiritualist movement. Podmore traces the historical development of Spiritualism from its earliest origins in animal magnetism and alchemy, to its apogee in the early nineteenth century and through to its decline from 1870 onwards, which Podmore associated with the growth of professional psychics and fraudsters. Volume 2, focusing on English and American Spiritualism, sets the movement in its cultural and intellectual context and includes a discussion of the relationship of Spiritualism to science. The volume includes invaluable accounts of scientific investigations into materialisations, spirit photographs, clairvoyance, hallucinations and automatism. It contains a summary and conclusion for the two volumes. Podmore was a leading member of the Victorian Society for Psychical Research and his work remains an indispensable source for the modern-day historian of n

Cognitive Developmental Change makes a fascinating contribution to the fields of developmental, cognitive and educational science by bringing together a uniquely diverse range of perspectives for analysing the dynamics of change. Connecting traditional Piagetian, information processing, and psychometric approaches with newer frameworks for the analysis of developmental change it provides the reader with an account of the latest theory and research at the time of publication. The contributors to the volume, all internationally respected experts, were asked when writing to consider three main aspects of cognitive change.

Is the human mind uniquely nonphysical or even spiritual, such that divine intentions can meet physical realities? As scholars in science and religion have spent decades attempting to identify a 'causal joint' between God and the natural world, human consciousness has been often privileged as just such a locus of divine-human interaction. However, this intuitively dualistic move is both out of step with contemporary science and theologically insufficient. By discarding the God-nature model implied by contemporary noninterventionist divine action theories, one is freed up to explore theological and metaphysical alternatives for understanding divine action in the mind. Sarah Lane Ritchie suggests that a theologically robust theistic naturalism offers a more compelling vision of divine action in the mind. By affirming that to be fully natural is to be involved with God's active presence, one may affirm divine action not only in the human mind, but throughout the natural world.
