Introduction to Python Programming And Data Structure By Liang

Concise and self-contained, this textbook gives a graduate-level introduction to the physical processes that shape planetary systems, covering all stages of planet formation. Writing for readers with undergraduate backgrounds in physics, astronomy, and planetary science, Armitage begins with a description of the structure and evolution of protoplanetary disks, moves on to the formation of planetesimals, rocky, and giant planets, and concludes by describing the gravitational and gas dynamical evolution of planetary systems. He provides a self-contained account of the modern theory of planet formation and, for more advanced readers, carefully selected references to the research literature, noting areas where research is ongoing. The second edition has been thoroughly revised to include observational results from NASA's Kepler mission, ALMA observations and the JUNO mission to Jupiter, new theoretical ideas including pebble accretion, and an up-to-date understanding in areas such as disk

This enduringly popular undergraduate textbook has been thoroughly reworked and updated, and now comprises twelve chapters covering the same breadth of topics as earlier editions, but in a substantially modernized fashion to facilitate classroom teaching. Covering both theoretical and applied aspects of geophysics, clear explanations of the physical principles are blended with step-by-step derivations of the key equations and over 400 explanatory figures to explain the internal structure and properties of the planet, including its petroleum and mineral resources. New topics include the latest data acquisition technologies, such as satellite geophysics, planetary landers, ocean bottom seismometers, and fibre optic methods, as well as recent research developments in ambient noise interferometry, seismic hazard analysis, rheology, and numerical modelling - all illustrated with examples from the scientific literature. Student-friendly features include separate text boxes with auxiliary exp

In this book, self-defence against non-state actors is examined by three scholars whose geographical, professional, theoretical, and methodological backgrounds and outlooks differ greatly. Their trialogue is framed by an introduction and a conclusion by the series editors. The novel scholarly format accommodates the pluralism and value changes of the current era, a shifting world order and the rise in nationalism and populism. It brings to light the cultural, professional and political pluralism which characterises international legal scholarship and exploits this pluralism as a heuristic device. This multiperspectivism exposes how political factors and intellectual styles influence the scholarly approaches and legal answers and the trialogical structure encourages its participants to decentre their perspectives. By explicitly focussing on the authors' divergence and disagreement, a richer understanding of self-defence against non-state actors is achieved, and the legal challenges and

Finite-state methods are the most efficient mechanisms for analysing textual and symbolic data, providing elegant solutions for an immense number of practical problems in computational linguistics and computer science. This book for graduate students and researchers gives a complete coverage of the field, starting from a conceptual introduction and building to advanced topics and applications. The central finite-state technologies are introduced with mathematical rigour, ranging from simple finite-state automata to transducers and bimachines as 'input-output' devices. Special attention is given to the rich possibilities of simplifying, transforming and combining finite-state devices. All algorithms presented are accompanied by full correctness proofs and executable source code in a new programming language, C(M), which focuses on transparency of steps and simplicity of code. Thus, by enabling readers to obtain a deep formal understanding of the subject and to put finite-state methods t

Technology entrepreneurship has been receiving growing importance as an effective instrument to promote national economic growth, both from empirical researchers and policymakers. India has emerged as the third largest base for high-tech start-ups in the world. Although there is a surge in start-up creation rates in India, little is known about factors required for these start-ups to survive, sustain and grow into large enterprises, particularly in the context of emerging economies like India. This book reviews the entrepreneurial, firm-specific and external environment-specific aspects that influence the key lifecycle stages of high-tech start-ups and identifies the key factors that influence each milestone. Existing literature in this subject has limited studies on the structure of the high-tech start-up sector and processes and strategies adapted by them. This book aims to address this gap, analyzing case studies and empirical data, and provides a multidimensional framework to under

This unique text provides a thorough, yet accessible, grounding in the mathematics, statistics, and programming that students need to master for coursework and research in climate science, meteorology, and oceanography.

Computational techniques are integrated to demonstrate how to visualize, analyze, and apply climate data, with R code featured in the book and both R and Python code available online. Exercises are provided at the end of each chapter with selected solutions available to students to aid self-study and further solutions provided online for instructors only. Additional online supplements to aid classroom teaching include datasets, images, and animations. Guidance is provided on how the book can support a variety of courses at different levels, making i

An accessible and thorough introduction to implicatures, a key topic in all frameworks of pragmatics. Starting with a definition of the various types of implicatures in Gricean, neo-Gricean and post-Gricean pragmatics, the book covers many important questions for current pragmatic theories, namely: the distinction between explicit and implicit forms of pragmatic enrichment, the criteria for drawing a line between semantic and pragmatic meaning, the relations between the structure of language (syntax) and its use (pragmatics), the social and cognitive factors underlying the use of implicatures by native speakers, and the factors influencing their acquisition for children and second language learners. Written in non-technical language, Implicatures will appeal to students and teachers in linguistics, applied linguistics, psychology and sociology, who are interested in how language is used for communication, and how children and learners develop pragmatic skills.

Sickles and Valentin Zelenyuk provide a comprehensive approach to productivity and efficiency analysis, covering its theoretical underpinnings and its empirical implementation, paying particular attention to the implications of neoclassical economic theory. A distinct feature of the book is that it presents a wide array of theoretical and empirical methods utilized by researchers and practitioners who study productivity issues. An accompanying website includes methods, programming codes that can be used with widely available software like MATLAB® and R, and test data for many of the productivity and efficiency estimators discussed in the book. It will be valuable to upper-level undergraduates, graduate students, and professional

What is a focus group? Why do we use them? When should we use them? When should we not? Focus Groups for the Social Science Researcher provides a step-by-step guide to undertaking focus groups, whether as a stand-alone method or alongside other qualitative or quantitative methods. It recognizes the challenges that focus groups encounter and provides tips to address them. The book highlights three unique, inter-related characteristics of focus groups. First, they are inherently social in form. Second, the data emerge organically through conversation; they are emic in nature. Finally, focus groups generate data at three levels of analysis: the individual, group, and interactive level. The book builds from these three characteristics to explain when focus groups can usefully be employed in different research designs. This is an essential text for students and researchers looking for a concise and accessible introduction to this important approach to data collection.

Recent years have witnessed an explosion in the volume and variety of data collected in all scientific disciplines and industrial settings.

The book provides a general introduction to blockchains as both a regulatable and a regulatory technology and outlines the interaction between distributed ledger technology and specific areas of EU law, such as the General Data Protection Regulation. It should be read by anyone interested in EU law, the relationship between law, innovation and technology, and technology governance.

During the 1970s and early 1980s, Egypt experienced swift economic growth resulting from a regional oil boom. Oddly, this economic growth hardly registered in Egyptian public discourse, which continuously claimed that the country was experiencing multiple economic, social, and cultural crises. This book sets out to investigate this discrepancy and to offer a revisionist history of the period. It documents the massive socio-economic mobility in Egypt by analysing relevant statistical data and ethnographic evidence, indicating the changes in the employment structure and the spread of mass consumption. Relli Shechter further examines a wide array of cultural resources, such as Egyptian academic writing, the press, the cinema, and the literature, in which critics lamented 'what went wrong' in Egypt. By doing so, he offers a local version of a wider Middle Eastern and international story: the global formation of middle-class societies whose members strove for respectable lives with only par

This volume provides a practical introduction to the method of maximum likelihood as used in social science research. Ward and Ahlquist focus on applied computation in R and use real social science data from actual, published research. Unique among books at this level, it develops simulation-based tools for model evaluation and selection alongside statistical inference. The book covers standard models for categorical data as well as counts, duration data, and strategies for dealing with data missingness. By working through examples, math, and code, the authors build an understanding about the contexts in which maximum likelihood methods are useful and develop skills in translating mathematical statements into executable computer code. Readers will not only be taught to use likelihood-based tools and generate meaningful interpretations, but they will also acquire a solid foundation for continued study of more advanced statistical techniques.

Do you use language corpora in your research or study, but find that you struggle with statistics?

The book gives step-by-step guidance through the process of statistical analysis and provides multiple examples of how statistical techniques can be used to analyse and visualise linguistic data. It also includes a useful selection of discussion questions and exercises which you can use to check your understanding. The book comes with a Companion website, which provides additional materials (answers to exercises, datasets, advanced materials, teaching slides etc.) and Lancaster Stats Tools online (http://corpora.lancs.ac.uk/stats), a free click-and-analyse statistical tool for easy calculation of the statistical measures discussed in the book.

Environmental problems are firmly on the political agenda. The stark threat to the planet from climate change, biodiversity loss and pollution can no longer be ignored by governments, political parties, businesses or individuals. Responding to the considerable developments of the last decade, Neil Carter has updated his popular textbook thoroughly, while retaining the existing structure of previous editions. The Politics of the Environment continues to analyse the relationship between 'green ideas' and other political doctrines, the development of green parties and public policymaking, and environmental issues at international, national and local levels. It provides students with a comprehensive comparative introduction to ideas, activism and policy. New to this edition are discussions on climate justice, climate legislation and recent environmental struggles, such as demonstrations against fracking. It employs a variety of global examples and includes pedagogical features such as boxe

Clays and clay minerals are the most abundant natural reactive solids on the Earth's surface.

These examples are supported by quantitative field data, including numerical and graphical depictions of clay and clay mineral occurrences. The book concludes by covering Critical Zone clay geochemistry and clay sequences, including the industrial, synthetic

This book explores the fundamentals of computer music and functional programming through the Haskell programming language. Functional programming is typically considered difficult to learn. This introduction in the context of creating music will allow students and professionals with a musical inclination to leverage their experience to help understand concepts that might be intimidating in more traditional computer science settings. Conversely, the book opens the door for programmers to interact with music by using a medium that is familiar to them. Readers will learn how to use the Euterpea library for Haskell (http://www.euterpea.com) to represent and create their own music with code, without the need for other music software. The book explores common paradigms used in algorithmic music composition, such as stochastic generation, musical grammars, self-similarity, and real-time interactive systems. Other topics covered include the basics of signal-based systems in Haskell, sound synt

All humans share certain components of tooth structure, but show variation in size and morphology around this shared pattern. This book presents a worldwide synthesis of the global variation in tooth morphology in recent populations. Research has advanced on many fronts since the publication of the first edition, which has become a seminal work on the subject. This revised and updated edition introduces new ideas in dental genetics and ontogeny and summarizes major historical problems addressed by dental morphology. The detailed descriptions of 29 dental variables are fully updated with current data and include details of a new web-based application for using crown and root morphology to evaluate ancestry in forensic cases. A new chapter describes what constitutes a modern human dentition in the context of the hominin fossil record.

Book VI of the Histories is one of Herodotus' most varied books, beginning with the final collapse of the Ionian Revolt and moving on to the Athenian triumph at Marathon (490 BC); it also includes fascinating material on Sparta, full of court intrigue and culminating in Kleomenes' grisly death, and there is comedy too, with Alkmeon's cramming clothes, boots, and even cheeks with gold dust, then Hippokleides 'dancing away his marriage'. In Herodotus' time, Marathon was already reaching almost legendary status, commemorated in epigrams and monuments, and in this edition a substantial introduction discusses Herodotus' relation to these other memorials. It also explores the place of the book in the Histories' overall structure, and pays particular attention to Herodotus' treatment of impiety. A new text is then accompanied by a full commentary, covering literary and historical aspects and offering help with translation. The volume is suitable for undergraduates, graduate students, teachers

Algebraic groups play much the same role for algebraists as Lie groups play for analysts. This book is the first comprehensive introduction to the theory of algebraic group schemes over fields that includes the structure theory of semisimple algebraic groups, and is written in the language of modern algebraic geometry. The first eight chapters study general algebraic group schemes over a field and culminate in a proof of the Barsotti–Chevalley theorem, realizing every algebraic group as an extension of an abelian variety by an affine group. After a review of the Tannakian philosophy, the author provides short accounts of Lie algebras and finite group schemes. The later chapters treat reductive algebraic groups over arbitrary fields, including the Borel–Chevalley structure theory. Solvable algebraic groups are studied in detail. Prerequisites have also been kept to a minimum so that the book is accessible to non-specialists in algebraic geometry.

This book opens with a simple introduction to financial markets, attempting to understand the action and the players of Wall Street by comparing them to the action and the players of main street. Firstly, it explores the definition of a security by its function, the departure from the buyer beware environment of corporate law and the entrance into the seller disclose environment of securities law. Secondly, it shows that the cost of disclosure rules is justified by their capacity to combat irrationalities, fads, and panics. The third section explains how the structure of class actions is designed to improve deterrence. Next it explores the economic harm from insider trading and how the law fights it. In sum, the book shows how all these parts of securities law serve the virtuous cycle from liquidity to accurate prices and more trading and how the great recession showed that our securities regulation reacted mostly adequately to the crisis.

Intended for practitioners of resilience engineering with a background in probability, this book offers a balanced blend of background, theor

Critical realism is a philosophy of science that positions itself against the major alternative philosophies underlying contemporary sociology. This book offers a general critique of sociology, particularly sociology in the United States, from a critical realist perspective. It also acts as an introduction to critical realism for students and scholars of sociology. Written in a lively, accessible style, Douglas V. Porpora argues that sociology currently operates with deficient accounts of truth, culture, structure, agency, and causality that are all better served by a critical realist perspective. This approach argues against the alternative sociological perspectives, in particular the dominant positivism which privileges statistical techniques and experimental design over ethnographic and historical approaches. However, the book also compares critical realism favourably with a range of other approaches, including poststructuralism, pragmatism, interpretivism, practice theory, and rela

Plato's Theaetetus and Sophist are two of his most important dialogues, and are widely read and discussed by philosophers for what they reveal about his epistemology and particularly his accounts of belief and knowledge. Although they form part of a single Platonic project, these dialogues are not usually presented as a pair, as they are in Christopher Rowe's new and lively translation. Offering a high standard of accuracy and readability, the translation reveals the continuity between these dialogues and others in the Platonic corpus, especially the Republic. The supporting introduction and notes help the reader to follow the arguments as they develop, explaining their structure, context and interpretation. This new edition challenges current scholarly approaches to Plato's work and will pave the way for fresh interpretations both of Theaetetus and Sophist and of Plato's writings in general.

Software is pervasive in our lives. We are accustomed to dealing with the failures of much of that software - restarting an application is a very familiar solution. Such solutions are unacceptable when the software controls our cars, airplanes and medical devices or manages our private information. These applications must run without error. SPARK provides a means, based on mathematical proof, to guarantee that a program has no errors. SPARK is a formally defined programming language and a set of verification tools specifically designed to support the development of software used in high integrity applications. Using SPARK, developers can formally verify properties of their code such as information flow, freedom from runtime errors, functional correctness, security properties and safety properties. Written by two SPARK experts, this is the first introduction to the just-released 2014 version. It will help students and developers alike master the basic concepts for building systems with

Democracy has provided opportunities for political representation and accountability, but it has also created incentives for creating and maintaining clientelistic networks. Why has clientelism consolidated with the introduction of democracy? Drawing on network analysis, Mobilizing Poor Voters answers this question by describing and explaining the emergence, maintenance, and disappearance of political, partisan, and social networks in Argentina. Combining qualitative and quantitative data gathered during twenty-four months of field research in eight municipalities in Argentina, Mobilizing Poor Voters shows that when party leaders distribute political promotions to party candidates based only on the number of voters they mobilize, party leaders incentivize the use of clientelistic strategies among candidates competing to mobilize voters in poor neighborhoods. The logic of perverse incentives examined in this book explains why candidates who use clientelism succeed in getting elected and
