Book Description
Principal component analysis is probably the oldest and best known of the It was first introduced by Pearson (1901), techniques ofmultivariate analysis. and developed independently by Hotelling (1933). Like many multivariate methods, it was not widely used until the advent of electronic computers, but it is now weIl entrenched in virtually every statistical computer package. The central idea of principal component analysis is to reduce the dimen sionality of a data set in which there are a large number of interrelated variables, while retaining as much as possible of the variation present in the data set. This reduction is achieved by transforming to a new set of variables, the principal components, which are uncorrelated, and which are ordered so that the first few retain most of the variation present in all of the original variables. Computation of the principal components reduces to the solution of an eigenvalue-eigenvector problem for a positive-semidefinite symmetrie matrix. Thus, the definition and computation of principal components are straightforward but, as will be seen, this apparently simple technique has a wide variety of different applications, as weIl as a number of different deri vations. Any feelings that principal component analysis is a narrow subject should soon be dispelled by the present book; indeed some quite broad topics which are related to principal component analysis receive no more than a brief mention in the final two chapters.

A Gravity's Rainbow Companion
Author: Steven C. Weisenburger
Publisher: University of Georgia Press
ISBN: 0820337641
Category : Literary Criticism
Languages : en
Pages : 433
Book Description
Adding some 20 percent to the original content, this is a completely updated edition of Steven Weisenburger's indispensable guide to Thomas Pynchon's Gravity's Rainbow. Weisenburger takes the reader page by page, often line by line, through the welter of historical references, scientific data, cultural fragments, anthropological research, jokes, and puns around which Pynchon wove his story. Weisenburger fully annotates Pynchon's use of languages ranging from Russian and Hebrew to such subdialects of English as 1940s street talk, drug lingo, and military slang as well as the more obscure terminology of black magic, Rosicrucianism, and Pavlovian psychology. The Companion also reveals the underlying organization of Gravity's Rainbow--how the book's myriad references form patterns of meaning and structure that have eluded both admirers and critics of the novel. The Companion is keyed to the pages of the principal American editions of Gravity's Rainbow: Viking/Penguin (1973), Bantam (1974), and the special, repaginated Penguin paperback (2000) honoring the novel as one of twenty "Great Books of the Twentieth Century."

Contouring Human Development
Author: Mukunda Mishra
Publisher: Springer Nature
ISBN: 9811540837
Category : Business & Economics
Languages : en
Pages : 387
Book Description
This book acquaints readers with a range of techniques to help them effectively identify, record, map, analyze and report on patterns in various dimensions of human development (HD) with spatial scales down to the village level. It is impossible to capture HD at the local and global scale with only a single index, because differences in HD at the international scale are caused by ‘general’ factors, whereas local-scale differences are influenced by ‘specific’ factors. This book offers a variety of methods for scientifically mapping HD at any spatial scale. It covers how to rationally select variables; how to test the models; how to validate the results, and how to analyze them. For this purpose, it employs a case study on an Indian district. The socio-economic factors regulating the patterns of HD are now more complex than they were only a few decades ago, making it essential to incorporate newer models in order to successfully ‘replicate’ the real-world situation. Accordingly, the book offers essential methodological tools & techniques for mapping HD. It sheds new light on a handful of statistical multivariate analysis and machine learning algorithms that are rarely used in the social sciences when dealing with HD, yet have sound mathematical and statistical bases. These techniques can be successfully used for predictive analysis in the earth & natural sciences, decision sciences and management disciplines, and are equally effective in terms of capturing, predicting and projecting the composite HD ‘landscape.’ This book will especially benefit two groups of readers: firstly, HD practitioners who want to find out ‘why some areas are doing better than others’ by exploring the complex interactions of spatially linked variables with different HD parameters. And secondly, practitioners in other branches of the social sciences who are not concerned with HD but are looking for ‘hands-on training’ with techniques they can apply in their respective field of spatial investigations.

The Remote Sensing of Tropospheric Composition from Space
Author: John P. Burrows
Publisher: Springer Science & Business Media
ISBN: 3642147917
Category : Technology & Engineering
Languages : en
Pages : 576
Book Description
The impact of anthropogenic activities on our atmospheric environment is of growing public concern and satellite-based techniques now provide an essential component of observational strategies on regional and global scales. The purpose of this book is to summarise the state of the art in the field in general, while describing both key techniques and findings in particular. It opens with an historical perspective of the field together with the basic principles of remote sensing from space. Three chapters follow on the techniques and on the solutions to the problems associated with the various spectral regions in which observations are made. The particular challenges posed by aerosols and clouds are covered in the next two chapters. Of special importance is the accuracy and reliability of remote sensing data and these issues are covered in a chapter on validation. The final section of the book is concerned with the exploitation of data, with chapters on observational aspects, which includes both individual and synergistic studies, and on the comparison of global and regional observations with chemical transport and climate models and the added value that the interaction brings to both. The book concludes with scientific needs and likely future developments in the field, and the necessary actions to be taken if we are to have the global observation system that the Earth needs in its present, deteriorating state. The appendices provide a comprehensive list of satellite instruments, global representations of some ancillary data such as fire counts and light pollution, a list of abbreviations and acronyms, and a set of colourful timelines indicating the satellite coverage of tropospheric composition in the foreseeable future. Altogether, this book will be a timely reference and overview for anyone working at the interface of environmental, atmospheric and space sciences.

Ocean Energy
Author: R. H. Charlier
Publisher: Springer Science & Business Media
ISBN: 3540779329
Category : Science
Languages : en
Pages : 270
Book Description
Engineers’ dreams and fossil energy replacement schemes can come true. Man has been tapping the energy of the sea to provide power for his industries for centuries. Tidal energy combined with that of waves and marine winds rank among those most successfully put the work. Large scale plants are capital intensive but smaller ones, particularly built in China, have proven profitable. Since the initiation of the St Malo project in France, similar projects have gone into active service where methods have been devised to cut down on costs, new types of turbines developed and cost competitiveness considerably improved. Tidal power has enormous potential. The book reviews recent progress in extracting power from the ocean, surveys the history of tidal power harnessing and updates a prior publication by the author.

Travel in the Byzantine World
Author: Ruth Macrides
Publisher: Taylor & Francis
ISBN: 1351877674
Category : History
Languages : en
Pages : 316
Book Description
This latest volume in the SPBS series makes a notable contribution to our understanding both of the evidence for travel, and of the realities and perceptions of communications in the Byzantine world. Four aspects of travel in the Byzantine world, from the 6th to the 15th century, are examined: technicalities of travel on land and sea, purposes of travel, foreign visitors' perceptions of Constantinople, and the representation of the travel experience in images and in written accounts. Sources used to illuminate these aspects include descriptions of journeys, pilot books, bilingual word lists, shipwrecks, monastic documents, but as the opening paper shows the range of such sources can be far wider than generally supposed. The contributors highlight road and travel conditions for horses and humans, types of ships and speed of sea journeys, the nature of trade in the Mediterranean, the continuity of pilgrimage to the Holy Land, attitudes toward travel. Patterns of communication in the Mediterranean are revealed through distribution of ceramic finds, letter collections, and the spread of the plague.
