Introduction to Python Programming And Data Structure By Liang

'Language attrition' describes the loss of, or changes to, grammatical and other features of a language as a result of declining use by speakers who have changed their linguistic environment and language habits. In such a situation there may, for example, be simplification in the tense system or in certain properties of subordinate clauses; some vocabulary items might fall into disuse and phonetic features may be restructured. These changes can be affected by features of the speaker's environment, but also by his or her attitudes and processes of identification. This book provides a detailed and up-to-date introduction to the way in which language attrition can affect language, as well as to the extra- and sociolinguistic features involved. It also familiarizes the reader with experimental approaches to attrition and data analysis techniques and provides hands-on guidelines on how to apply them.

The instability of fluid flows is a key topic in classical fluid mechanics because it has huge repercussions for applied disciplines such as chemical engineering, hydraulics, aeronautics, and geophysics. This modern introduction is written for any student, researcher, or practitioner working in the area, for whom an understanding of hydrodynamic instabilities is essential. Based on a decade's experience of teaching postgraduate students in fluid dynamics, this book brings the subject to life by emphasizing the physical mechanisms involved. The theory of dynamical systems provides the basic structure of the exposition, together with asymptotic methods. Wherever possible, Charru discusses the phenomena in terms of characteristic scales and dimensional analysis. The book includes numerous experimental studies, with references to videos and multimedia material, as well as over 150 exercises which introduce the reader to new problems.

This is a 1958 study of the scattering of particles which occurs when atomic nuclei collide. It provides one of the main lines of attack in exploring the forces within the nuclei themselves. Using the particle accelerators which were then available, the authors design experiments in which the less complex particles collide under controlled conditions, yielding quantitative data from which information about nuclear forces can be deduced. This book describes the physics of nuclear scattering, including the experimental results and their interpretation in terms of nuclear forces and nuclear structure. On the experimental side, standard equipment has been discussed only in the special context of scattering technique. The theoretical discussion assumes a general acquaintance with quantum mechanics and with elementary scattering formulae encountered elsewhere in relation to the scattering of electrons by atoms.

Azoles are five-membered cyclic compounds containing one or more heteroatoms in the ring, at least one of which must be nitrogen. The rings contain the maximum number of non-cumulative double bonds consistent with the normal valencies of the ring atoms. This 1976 volume sets out in detail the structure and properties of these compounds and their derivatives. After an introduction and a section dealing with general physical properties there is an extensive discussion of electrophilic and nucleophilic substitution reactions. This is followed by a description of the types of reaction which modify the nucleus of the azole family. A short section on photochemical reactions compares those reactions which are not easy to classify with the thermolyses discussed in the previous chapter. To complete the work there is an extensive discussion of the properties of functional side groups and an extensive bibliography detailing about 1500 publications on azole chemistry.

This 2002 introduction to the use of radar for remote sensing of natural surfaces provides the reader with a thorough grounding in practical applications, focusing particularly on terrestrial studies that may be extended to other planets. An historical overview of the subject is followed by an introduction to the nomenclature and methodology pertaining to radar data collection, image interpretation and surface roughness analysis. The author then presents a summary (illustrated with black and white examples from the natural environment) of theoretical explanations for the backscatter properties of continuous rough surfaces, collections of discrete objects, and layered terrain. Case studies of radar surveys of the Moon, Mercury, Venus and Mars complete the book. The level is appropriate for students and professionals across a broad range of scientific disciplines including Earth and planetary sciences, electrical engineering, and remote sensing. Particular emphasis is given to practical

This book investigates the relationship between the character of political regimes in Russia's subnational regions and the structure of earnings and income. Based on extensive data from Russian official sources and surveys conducted by the World Bank, the book shows that income inequality is higher in more pluralistic regions. It argues that the relationship between firms and government differs between more democratic and more authoritarian regional regimes. In more democratic regions, business firms and government have more cooperative relations, restraining the power of government over business and encouraging business to invest more, pay more and report more of their wages. Average wages are higher in more democratic regions and poverty is lower, but wage and income inequality are also higher. The book argues that the rising inequality in postcommunist Russia reflects the inability of a weak state to carry out a redistributive social policy.

One of the nine canonical Greek lyric poets, Pindar (c. 522–443 BCE) has enjoyed a brilliant reputation since antiquity. Notoriously challenging but widely respected, Pindar's poetry has been increasingly studied in modern times. In the late nineteenth century, C. A. M. Fennell (1843–1916), a classicist and Fellow of Jesus College, Cambridge, turned his attention to Pindar's Nemean and Isthmian odes. First published in 1883 but released in a new edition in 1899, this book features an introduction focusing on the practical aspects of the pentathlon, which sets a good grounding for the comprehension of the odes themselves. Touching on metrical structure, this edition then presents each ode in its original Greek, accompanied by an individual, detailed introduction and full commentary. This fascinating work will be of value to advanced students of Greek grappling with the intricacies of Pindar's complex poetry.

He also describes emerging technologies critical to cloud computing. The book also covers the fundamentals of enterprise computing, including a technical introduction to enterprise architecture, so it will interest programmers aspiring to become software architects and serve as a re

Richard Bird takes a radical approach to algorithm design, namely, design by calculation. These 30 short chapters each deal with a particular programming problem drawn from sources as diverse as games and puzzles, intriguing combinatorial tasks, and more familiar areas such as data compression and string matching. Each pearl starts with the statement of the problem expressed using the functional programming language Haskell, a powerful yet succinct language for capturing algorithmic ideas clearly and simply. The novel aspect of the book is that each solution is calculated from an initial formulation of the problem in Haskell by appealing to the laws of functional programming. Pearls of Functional Algorithm Design will appeal to the aspiring functional programmer, students and teachers interested in the principles of algorithm design, and anyone seeking to master the techniques of reasoning about programs in an equational style.

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 2004 book is an accessible and comprehensive introduction to machine vision.

Linguistics, neurocognition, and phenomenological psychology are fundamentally different fields of research. Helmut Schnelle provides an interdisciplinary understanding of a new integrated field in which linguists can be competent in neurocognition and neuroscientists in structure linguistics. Consequently the first part of the book is a systematic introduction to the function of the form and meaning-organising brain component - with the essential core elements being perceptions, actions, attention, emotion and feeling. Their descriptions provide foundations for experiences based on semantics and pragmatics. The second part is addressed to non-linguists and presents the structural foundations of currently established linguistic frameworks. This book should be serious reading for anyone interested in a comprehensive understanding of language, in which evolution, functional organisation and hierarchies are explained by reference to brain architecture and dynamics.

The electroweak theory unifies two basic forces of nature: the weak force and electromagnetism. This 2007 book is a concise introduction to the structure of the electroweak theory and its applications. It describes the structure and properties of field theories with global and local symmetries, leading to the construction of the standard model. It describes the particles and processes predicted by the theory, and compares them with experimental results. It also covers neutral currents, the properties of W and Z bosons, the properties of quarks and mesons containing heavy quarks, neutrino oscillations, CP-asymmetries in K, D, and B meson decays, and the search for Higgs particles. Each chapter contains problems, stemming from the long teaching experience of the author, to supplement the text. This will be of great interest to graduate students and researchers in elementary particle physics.

As real estate forms a significant part of the asset portfolios of most investors and lenders, it is crucial that analysts and institutions employ sound techniques for modelling and forecasting the performance of real estate assets. Assuming no prior knowledge of econometrics, this book introduces and explains a broad range of quantitative techniques that are relevant for the analysis of real estate data. It includes numerous detailed examples, giving readers the confidence they need to estimate and interpret their own models. Throughout, the book emphasises how various statistical techniques may be used for forecasting and shows how forecasts can be evaluated. Written by a highly experienced teacher of econometrics and a senior real estate professional, both of whom are widely known for their research, Real Estate Modelling and Forecasting is the first book to provide a practical introduction to the econometric analysis of real estate for students and practitioners.

These lively narrative poems, attributed in antiquity to Homer, are works of great charm. Composed for recitation at festivals in honour of the gods, they tell of Apollo's birth on the island of Delos and his foundation of the Delphic oracle; Hermes' invention of the lyre and theft of his brother Apollo's cattle; and Aphrodite's love affair with the mortal Anchises. This edition offers a new text of these poems. The Introduction discusses among other things the nature and purpose of the poems in general, their origins, their structure and themes. The Commentary brings out the individual character of each Hymn, by analyzing in depth its language and literary qualities, and also its religious and historical aspects. The aim is to make these Hymns more accessible to students of Greek literature, and help them to appreciate the poems more fully as major works of early Greek poetry.

This 1994 book analyses wage hierarchy in market and planning theory, and how these theories can be used as a basis for the comparison of wage structures in Western and Soviet-type systems. The author analyses statistical data from ten countries in both systems at the beginning of the eighties, and attempts to account for wage dispersion by examining such factors as education and training, discrimination against women, and market structure, as well as the influence of systemic factors. Professor Redor asserts that systemic differences are not the most significant determinants of wage inequality (the Soviet Union is found to have been on a par with the United Kingdom for example), and argues that similarities between the two systems in the dispersion of wages are due to similar patterns of work organisation and wage policies within firms, and that many determinants of wage inequality are in fact common to both systems.

Karl Brugmann originally intended to include a volume on syntax in his comparative grammar of Indo-European, but as that ambitious project expanded, he and his publisher enlisted Berthold Delbrück (1842–1922) to take on the treatment of syntax. Delbrück's three volumes on inflection and phrase and sentence structure appeared between 1893 and 1900 and remain the fullest treatment of Indo-European syntax to this day. In this, his first volume, Delbrück gives an overview of the prevailing academic positions in the field of Indo-European comparative syntax of his day. He applies the Neogrammarian methodology used by Brugmann, and meticulously presents data relating to nouns, the case system, adjectives, pronouns, numerals, adverbs and prepositions, giving particular attention to the ablative and the dative in a number of Indo-European languages.

Theodor Koch-Grünberg (1872–1924) was a noted German ethnologist and explorer whose work on the indigenous peoples of Brazil and Venezuela is still consulted by anthropologists, ethnologists and linguists today. His most important publication was this five-volume account of his expedition of 1911–1913 from the sandstone mountains bordering Brazil, Venezuela and Guyana through uncharted territory westwards to the Orinoco. Volume 5 contains 185 photographs of individuals and groups selected from around 350 taken by the author. His intention was to provide data on the physical characteristics of the tribes he encountered before the distinctions between them became blurred or vanished. Exact measurements and precise ages are not provided, but the author explains how individuals are related, gives their indigenous and 'Christian' names and social status, and provides a 'pen-portrait' for people he came to know personally. A short introduction provides contextualising information about geogr
