Introduction to Programming Concepts With Case Studies in Python

Thomas Carlyle (1795–1881) was one of the most influential authors of the nineteenth century. Eagerly studied at the highest level of intellectual society, his satirical essays and perceptive historical biographies caused him to be regarded for much of the Victorian period as a literary genius and eminent social philosopher. After graduating from Edinburgh University in 1814, he published his first scholarly work on German literature in 1824, before finding literary success with his history of the French Revolution in 1837. After falling from favour during the first part of the twentieth century, his work has more recently become the subject of scholarly re-examination. His introduction of German literature and philosophy into the British intellectual milieu profoundly influenced later philosophical ideas and literary studies. These volumes are reproduced from the 1896 Centenary Edition of his collected works. Volume 9 contains the fourth volume of Oliver Cromwell's Letters and Speeche

Mathematical modeling, analysis and simulation are set to play crucial roles in explaining tumor behavior, and the uncontrolled growth of cancer cells over multiple time and spatial scales. This book, the first to integrate state-of-the-art numerical techniques with experimental data, provides an in-depth assessment of tumor cell modeling at multiple scales. The first part of the text presents a detailed biological background with an examination of single-phase and multi-phase continuum tumor modeling, discrete cell modeling, and hybrid continuum-discrete modeling. In the final two chapters, the authors guide the reader through problem-based illustrations and case studies of brain and breast cancer, to demonstrate the future potential of modeling in cancer research. This book has wide interdisciplinary appeal and is a valuable resource for mathematical biologists, biomedical engineers and clinical cancer research communities wishing to understand this emerging field.

Neorealists argue that all states aim to acquire power and that state cooperation can therefore only be temporary, based on a common opposition to a third country. This view condemns the world to endless conflict for the indefinite future. Based upon careful attention to actual historical outcomes, this book contends that, while some countries and leaders have demonstrated excessive power drives, others have essentially underplayed their power and sought less position and influence than their comparative strength might have justified. Featuring case studies from across the globe, History and Neorealism examines how states have actually acted. The authors conclude that leadership, domestic politics, and the domain (of gain or loss) in which they reside play an important role along with international factors in raising the possibility of a world in which conflict does not remain constant and, though not eliminated, can be progressively reduced.

According to the Institute of Medicine (IOM) and U.S. Food and Drug Administration (FDA), 'developing new scientific approaches to detecting, understanding, predicting and preventing adverse events' was a critical path to the future of drug safety. This book brings together a collection of state-of-the-art chapters, written by experts in the drug safety field. It provides information on the present knowledge of drug side effects and their mitigation strategy during drug discovery, gives guidance for risk assessment and promotes evidence-based toxicology. Each specific area of toxicology relevant for drug discovery is discussed in detail, including theory, experimental approaches and data interpretation supported by comprehensive up-to-date references. Many chapters provide fascinating case studies, which are of general interest for those who have basic science training and are interested in how chemicals interact with the human body.

Homology theory is a powerful algebraic tool that is at the centre of current research in topology and its applications. This accessible textbook will appeal to mathematics students interested in the application of algebra to geometrical problems, specifically the study of surfaces (sphere, torus, Mobius band, Klein bottle). In this introduction to simplicial homology - the most easily digested version of homology theory - the author studies interesting geometrical problems, such as the structure of two-dimensional surfaces and the embedding of graphs in surfaces, using the minimum of algebraic machinery and including a version of Lefschetz duality. Assuming very little mathematical knowledge, the book provides a complete account of the algebra needed (abelian groups and presentations), and the development of the material is always carefully explained with proofs given in full detail. Numerous examples and exercises are also included, making this an ideal text for undergraduate courses

One of the most pressing issues confronting the multilateral trade system is the challenge posed by the rapid proliferation of preferential trade agreements. Plenty has been written about why governments might choose to negotiate preferentially or multilaterally, but until now it has been written almost exclusively from the perspective of governments. We know very little about how non-state actors view this issue of 'forum choice', nor how they position themselves to influence choices by governments about whether to emphasize PTAs or the WTO. This book addresses that issue squarely through case studies of trade policy-making and forum choice in eight developing countries: Chile, Colombia, Mexico, South Africa, Kenya, Jordan, Indonesia and Thailand. The case studies are based on original research by the authors, including interviews with state and non-state actors involved in the trade policy-making process in the eight countries of this study.

In the face of decreasing biodiversity and ongoing global changes, maintaining ecosystem functioning is seen both as a means to preserve biological diversity as well as for safeguarding human well-being by securing the services ecosystems provide. The concept today is prominent in many fields of ecology and conservation biology, such as biodiversity research, ecosystem management, or restoration ecology. Although the idea of ecosystem functioning is important, the concept itself remains rather vague and elusive. This book provides a novel analysis and integrated synthesis of different approaches to conceptualising and assessing ecosystem functioning. It links the natural sciences with methodologies from philosophy and the social sciences, and introduces a new methodology for a clearer and more efficient application of ecosystem functioning concepts in practice. Special emphasis is laid on the social dimensions of the concept and the ways it influences research practice. Several case st

This comprehensive introduction to the calculus of variations and its main principles also presents their real-life applications in various contexts: mathematical physics, differential geometry, and optimization in economics. Based on the authors' original work, it provides an overview of the field, with examples and exercises suitable for graduate students entering research. The method of presentation will appeal to readers with diverse backgrounds in functional analysis, differential geometry and partial differential equations. Each chapter includes detailed heuristic arguments, providing thorough motivation for the material developed later in the text. Since much of the material has a strong geometric flavor, the authors have supplemented the text with figures to illustrate the abstract concepts. Its extensive reference list and index also make this a valuable resource for researchers working in a variety of fields who are interested in partial differential equations and functional

Where was the chair of Mary Queen of Scots placed for her trial? How was Smithfield set up for public executions? How many paces did the King walk forward to meet a visiting ambassador in the Presence Chamber at Greenwich? How were spectators arranged at tournaments? And why did any of this matter? Janette Dillon adds a new dimension to work on space and theatricality by providing a comparative analysis of a range of spectacular historical events. She investigates in detail the claim that early modern court culture was always inherently performative, demonstrating how every kind of performance was shaped by its own space and place. Using a range of evidence, visual as well as verbal, and illustrated with some unfamiliar as well as better known images, Dillon leads the reader to general principles and conclusions via a range of minutely observed case studies.

From optical fundamentals to advanced applications, this comprehensive guide to micro-optics covers all the key areas for those who need an in-depth introduction to micro-optic devices, technologies, and applications. Topics covered range from basic optics, optical materials, refraction, and diffraction, to micro-mirrors, micro-lenses, diffractive optics, optoelectronics, and fabrication. Advanced topics, such as tunable and nano-optics, are also discussed. Real-world case studies and numerous worked examples are provided throughout, making complex concepts easier to follow, whilst an extensive bibliography provides a valuable resource for further study. With exercises provided at the end of each chapter to aid and test understanding, this is an ideal textbook for graduate and advanced undergraduate students taking courses in optics, photonics, micro-optics, microsystems, and MEMs. It is also a useful self-study guide for research engineers working on optics development.

Indispensable for students, invaluable for researchers, this comprehensive treatment of contemporary quasi–Monte Carlo methods, digital nets and sequences, and discrepancy theory starts from scratch with detailed explanations of the basic concepts and then advances to current methods used in research. As deterministic versions of the Monte Carlo method, quasi–Monte Carlo rules have increased in popularity, with many fruitful applications in mathematical practice. These rules require nodes with good uniform distribution properties, and digital nets and sequences in the sense of Niederreiter are known to be excellent candidates. Besides the classical theory, the book contains chapters on reproducing kernel Hilbert spaces and weighted integration, duality theory for digital nets, polynomial lattice rules, the newest constructions by Niederreiter and Xing and many more. The authors present an accessible introduction to the subject based mainly on material taught in undergraduate courses wi

Everyone working in and with organizations will, from time to time, experience frustrations and problems when trying to accomplish tasks that are a required part of their role. This is an unusual routine - a recurrent interaction pattern in which someone encounters a problem when trying to accomplish normal activities by following standard organizational procedures and then becomes enmeshed in wasteful and even harmful subroutines while trying to resolve the initial problem. They are unusual because they are not intended or beneficial, and because they are generally pervasive but individually infrequent. They are routines because they become systematic as well as embedded in ordinary functions. Using a wide range of case studies and interdisciplinary research, this book provides researchers and practitioners with a new vocabulary for identifying, understanding, and dealing with this pervasive organizational phenomenon, in order to improve worker and customer satisfaction as well as org

Responsible fisheries management is of increasing interest to the scientific community, resource managers, policy makers, stakeholders and the general public. Focusing solely on managing one species of fish stock at a time has become less of a viable option in addressing the problem. Incorporating more holistic considerations into fisheries management by addressing the trade-offs among the range of issues involved, such as ecological principles, legal mandates and the interests of stakeholders, will hopefully challenge and shift the perception that doing ecosystem-based fisheries management is unfeasible. Demonstrating that EBFM is in fact feasible will have widespread impact, both in US and international waters. Using case studies, underlying philosophies and analytical approaches, this book brings together a range of interdisciplinary topics surrounding EBFM and considers these simultaneously, with an aim to provide tools for successful implementation and to further the debate on EBF

The dictionary definition of tradition refers to beliefs and practices that have been transmitted from generation to generation, however, 'tradition' can rest simply on the claim that certain cultural elements are rooted in the past. Claim and documented historical reality need not overlap. In the domain of religion, historically verifiable traditions coexist with recent innovations whose origins are spuriously projected back into time. This book examines the phenomenon of 'invented traditions' in religions ranging in time from Zoroastrianism to Scientology, and geographically from Tibet to North America and Europe. The various contributions, together with an introduction that surveys the field, use individual case studies to address questions such as the rationale for creating historical tradition for one's doctrines and rituals; the mechanisms by which hitherto unknown texts can enter an existing corpus; and issues of acceptance and scepticism in the reception of dubious texts.

Human Rights and the Ethics of Globalization provides a balanced, thoughtful discussion of the globalization of the economy and the ethical considerations inherent in the many changes it has prompted. The book's introduction maps out the philosophical foundations for constructing an ethic of globalization, taking into account both traditional and contemporary sources. These ideals are applied to four specific test cases: the ethics of investing in China, the case study of the Firestone company's presence in Liberia, free-trade and fair-trade issues pertaining to the coffee trade with Ethiopia and the use of low-wage factories in Mexico to serve the US market. The book concludes with a comprehensive discussion of how to enforce global compliance with basic human rights standards, with particular attention to stopping abuses by multinational corporations through litigation under the Alien Tort Claims Act.

The sports business has become one of the fastest-growing industries in recent years. Sports organizations now have the potential to generate massive amounts of revenue through a variety of different channels, including broadcasting rights, advertising and branding. However, the rise of sports-related business has so far received relatively little attention from management scholars and social scientists. This book argues that we can no longer afford to ignore this important economic and social phenomenon. It presents a conceptual framework based on the concept of value creation to show how we can understand and explain the success and failure of sports organizations. Key concepts are illustrated with case studies of sporting organizations, including Real Madrid, FC Barcelona and the Americas Cup. Written by a team of authors from one of Spain's leading business schools, it provides a unique set of theoretical and practical insights for researchers and sports organization managers.

Econophysics is an emerging interdisciplinary field that takes advantage of the concepts and methods of statistical physics to analyse economic phenomena. This book expands the explanatory scope of econophysics to the real economy by using methods from statistical physics to analyse the success and failure of companies. Using large data sets of companies and income-earners in Japan and Europe, a distinguished team of researchers show how these methods allow us to analyse companies, from huge corporations to small firms, as heterogeneous agents interacting at multiple layers of complex networks. They then show how successful this approach is in explaining a wide range of recent findings relating to the dynamics of companies. With mathematics kept to a minimum, the book is not only a lively introduction to the field of econophysics but also provides fresh insights into company behaviour.

This new, fully-revised edition covers all the major topics of digital signal processing (DSP) design and analysis in a single, all-inclusive volume, interweaving theory with real-world examples and design trade-offs. Building on the success of the original, this edition includes new material on random signal processing, a new chapter on spectral estimation, greatly expanded coverage of filter banks and wavelets, and new material on the solution of difference equations. Additional steps in mathematical derivations make them easier to follow, and an important new feature is the do-it-yourself section at the end of each chapter, where readers get hands-on experience of solving practical signal processing problems in a range of MATLAB experiments. With 120 worked examples, 20 case studies, and almost 400 homework exercises, the book is essential reading for anyone taking DSP courses. Its unique blend of theory and real-world practical examples also makes it an ideal reference for practiti

One of the key questions in cognitive psychology is how people represent knowledge about concepts such as football or love. Some researchers have proposed that concepts are represented in human memory by the sensorimotor systems that underlie interaction with the outside world. These theories represent developments in cognitive science to view cognition no longer in terms of abstract information processing, but in terms of perception and action. In other words, cognition is grounded in embodied experiences. Studies show that sensory perception and motor actions support understanding of words and object concepts. Moreover, even understanding of abstract and emotion concepts can be shown to rely on more concrete, embodied experiences. Finally, language itself can be shown to be grounded in sensorimotor processes. This book brings together theoretical arguments and empirical evidence from several key researchers in this field to support this framework.

This 2004 book is an accessible and comprehensive introduction to machine vision. It provides all the necessary theoretical tools and shows how they are applied in actual image processing and machine vision systems. A key feature is the inclusion of many programming exercises that give insights into the development of practical image processing algorithms. The authors begin with a review of mathematical principles and go on to discuss key issues in image processing such as the description and characterization of images, edge detection, restoration and feature extraction, segmentation, texture and shape. They also discuss image matching, statistical pattern recognition, clustering, and syntactic pattern recognition. Important applications are described, including optical character recognition and automatic target recognition. Software and data used in the book can be found at www.cambridge.org/9780521830461. A useful reference for practitioners, the book is aimed at graduate students in

In 2002, an introductory workshop was held at the Mathematical Sciences Research Institute in Berkeley to survey some of the many directions of the commutative algebra field. Six principal speakers each gave three lectures, accompanied by a help session, describing the interaction of commutative algebra with other areas of mathematics for a broad audience of graduate students and researchers. This book is based on those lectures, together with papers from contributing researchers. David Benson and Srikanth Iyengar present an introduction to the uses and concepts of commutative algebra in the cohomology of groups. Mark Haiman considers the commutative algebra of n points in the plane. Ezra Miller presents an introduction to the Hilbert scheme of points to complement Professor Haiman's paper. Further contributors include David Eisenbud and Jessica Sidman; Melvin Hochster; Graham Leuschke; Rob Lazarsfeld and Manuel Blickle; Bernard Teissier; and Ana Bravo.

Originally published in 1995, Cohomology of Drinfeld Modular Varieties aimed to provide an introduction, in two volumes, both to this subject and to the Langlands correspondence for function fields. These varieties are the analogues for function fields of the Shimura varieties over number fields. The Langlands correspondence is a conjectured link between automorphic forms and Galois representations over a global field. By analogy with the number-theoretic case, one expects to establish the conjecture for function fields by studying the cohomology of Drinfeld modular varieties, which has been done by Drinfeld himself for the rank two case. The present volume is devoted to the geometry of these varieties, and to the local harmonic analysis needed to compute their cohomology. Though the author considers only the simpler case of function rather than number fields, many important features of the number field case can be illustrated.

In the celebrated words of Sir William Temple, the Dutch Republic of the United Provinces was 'the fear of some, the envy of others, and the wonder of all their neighbours'. This 1996 book looks at the history of the Dutch Republic from a comparative perspective, and provides a comparative study of key issues in Dutch history from the late sixteenth to the mid-nineteenth century. Contributors examine political, cultural, economic and social developments in the Netherlands in an interrelated way, and in doing so shed light on historical developments in other parts of west and central Europe. In contrast with previous comparative studies in European early modern history, this book concentrates on comparisons within the central belt of Europe running from north Italy through southern Germany, Flanders, the Dutch Republic and England. An editorial introduction and conclusion place the individual chapters within a coherent framework.

From the conversion of the emperor Constantine in the early fourth century, vast sums of money were spent on the building and sumptuous decoration of churches. The resulting works of art contain many of the greatest monuments of late antique and early medieval society. But how did such expenditure fit with Christ's message of poverty and simplicity? In attempting to answer that question, this 1998 study employs theories on the use of metaphor to show how physical beauty could stand for spiritual excellence. As well as explaining the evolving attitudes to sanctity, decorum and display in Roman and medieval society, detailed analysis is made of case studies of Latin biblical exegesis and gold-ground mosaics so as to counterpoint the contemporary use of gold as a Christian image in art and text.
