Latent Curve Models: A Structural Equation Perspective (Wiley Series in Probability and Statistics)

Latent Curve Models: A Structural Equation Perspective (Wiley Series in Probability and Statistics)
Wiley-Interscience | ISSN: 047145592X | 2005-12-23 | PDF | 312 Pages | 6,6 Mb

This volume represents a comprehensive treatment of a model sometimes referred to as latent curve or growth curve models. Latent Curve Models analyzes LTMs from the perspective of structural equation modeling (SEM) with latent variables. Although the authors discuss simple regression-based procedures that are helpful in the early stages of LTM, most of the presentation will use SEMs as a driving tool throughout the text.

Mathematical Discourse: Language, Symbolism And Visual Images

Kay L. O'Halloran “Mathematical Discourse: Language, Symbolism And Visual Images"
Continuum International Publishing Group | 2005-01-30 | ISBN: 0826468578 | 226 pages | PDF | 11,7 MB

This book develops a theory of mathematics as a multi-semiotic discourse from the perspective of M. A. K. Halliday's systemic functional linguistics. From this perspective mathematical discourse is seen to involve the use of the three semiotic resources of language, visual images and mathematical symbolism. These semiotic resources are considered as functional sign systems which are organised grammatically. O'Halloran suggests that mathematical texts represent specific semiotic choices from the available grammatical systems. From this she articulates the ways in which a social semiotic perspective can inform mathematics teaching and learning.

Completeness Theory for Propositional Logics (Studies in Universal Logic)

Completeness Theory for Propositional Logics (Studies in Universal Logic)
Birkhäuser Basel | Pages: 178 | 2008 | ISBN: 3764385170 | 2 MB | PDF

The book develops the theory of one of the most important notions in the methodology of formal systems. Particularly, completeness plays an important role in propositional logic where many variants of the notion have been defined. Global variants of the notion mean the possibility of getting all correct and reliable schemata of inference. Its local variants refer to the notion of truth given by some semantics. A uniform theory of completeness in its general and local meaning is carried out and it generalizes and systematizes some variety of the notion of completeness such as Post-completeness, structural completeness and many others. This approach allows also for a more profound view upon some essential properties (e.g. two-valuedness) of propositional systems. For these purposes, the theory of logical matrices, and the theory of consequence operations is exploited.

Generalized Curvatures

Jean-Marie Morvan “Generalized Curvatures"
Springer | 2008-06 | ISBN: 354073791X | 266 pages | PDF | 5,2 Mb

The intent of this book is to set the modern foundations of the theory of generalized curvature measures. This subject has a long history, beginning with J. Steiner (1850), H. Weyl (1939), H. Federer (1959), P. Wintgen (1982), and continues today with young and brilliant mathematicians. In the last decades, a renewal of interest in mathematics as well as computer science has arisen (finding new applications in computer graphics, medical imaging, computational geometry, visualization …).

Following a historical and didactic approach, the book introduces the mathematical background of the subject, beginning with curves and surfaces, going on with convex subsets, smooth submanifolds, subsets of positive reach, polyhedra and triangulations, and ending with surface reconstruction. We focus on the theory of normal cycle, which allows to compute and approximate curvature measures of a large class of smooth or discrete objects of the Euclidean space. We give explicit computations when the object is a 2 or 3 dimensional polyhedron.

This book can serve as a textbook to any mathematician or computer scientist, engineer or researcher who is interested in the theory of curvature measures.]]> free book city Thu, 15 May 2008 23:55:26 +0430 Handbook of Dynamical Systems : Volume 1A http://www.freebookcity.com/2008/05/15/handbook-of-dynamical-systems-volume-1a.html http://www.freebookcity.com/2008/05/15/handbook-of-dynamical-systems-volume-1a.html

The presentation attains coherence through a major introductory survey by the editors that organizes the entire subject, and by ample cross-references between individual surveys.
The volumes are a valuable resource for dynamicists seeking to acquaint themselves with other specialties in the field, and to mathematicians active in other branches of mathematics who wish to learn about contemporary ideas and results dynamics. Assuming only general mathematical knowledge the surveys lead the reader towards the current state of research in dynamics.]]> free book city Thu, 15 May 2008 22:58:47 +0430 The Mobius Strip: Dr. August Mobius's Marvelous Band in Mathematics, Games, Literature, Art, Technology, and Cosmology http://www.freebookcity.com/2008/05/04/the-mobius-strip.html http://www.freebookcity.com/2008/05/04/the-mobius-strip.html

The Mobius Strip: Dr. August Mobius's Marvelous Band in Mathematics, Games, Literature, Art, Technology, and Cosmology

The road that leads from the Möbius strip—a common-sense-defying continuous loop with only one side and one edge, made famous by the illustrations of M.C. Escher—goes to some of the strangest spots imaginable. It takes us to a place where the purely intellectual enters our daily world: where our outraged senses, overloaded with grocery bills, the price of gas, and what to eat for lunch, are expected to absorb really bizarre ideas. And no better guide to this weird universe exists than the brilliant thinker Clifford A. Pickover, the 21st century's answer to Buckminster Fuller. Come along as Pickover traces the origins of the Möbius strip from the mid-1800s, when the visionary scientist Dr. August Möbius became the first to describe the properties of one-sided surfaces, to the present, where it is an integral part of mathematics, magic, science, art, engineering, literature, and music. It has become a metaphor for change, strangeness, looping, and rejuvenation. Touching on everything from molecules and metal sculptures to postage stamps, architectural structures, and models of our entire universe, The Möbius Strip is lavishly illustrated and gives readers a glimpse into other worlds and new ways of thinking as Pickover reaches across cultures and dimensions.]]> free book city Sun, 04 May 2008 07:46:52 +0430 Stochastic Processes http://www.freebookcity.com/2008/04/30/stochastic-processes.html http://www.freebookcity.com/2008/04/30/stochastic-processes.html

SAS for Forecasting Time Series

John C., Ph.D. Brocklebank, David A. Dickey “SAS for Forecasting Time Series"
SAS Publishing | 2003-04-18 | ISBN: 1590471822 | 420 pages | PDF | 5,3 Mb

In this second edition of the indispensable SAS for Forecasting Time Series, Brocklebank and Dickey show you how SAS performs univariate and multivariate time series analysis. Taking a tutorial approach, the authors focus on the procedures that most effectively bring results: the advanced procedures ARIMA, SPECTRA, STATESPACE, and VARMAX. They demonstrate the interrelationship of SAS/ETS procedures with a discussion of how the choice of a procedure depends on the data to be analyzed and the results desired. With this book, you will learn to model and forecast simple autoregressive (AR) processes using PROC ARIMA, and you will learn to fit autoregressive and vector ARMA processes using the STATESPACE and VARMAX procedures. Other topics covered include detecting sinusoidal components in time series models, performing bivariate cross-spectral analysis, and comparing these frequency-based results with the time domain transfer function methodology. New and updated examples in the second edition include retail sales with seasonality, ARCH models for stock prices with changing volatility, vector autoregression and cointegration models, intervention analysis for product recall data, expanded discussion of unit root tests and nonstationarity, and expanded discussion of frequency domain analysis and cycles in data.]]> free book city Wed, 30 Apr 2008 10:10:47 +0430 Pattern Recognition http://www.freebookcity.com/2008/04/30/pattern-recognition.html http://www.freebookcity.com/2008/04/30/pattern-recognition.html

Twenty-Four Hours of Local Cohomology

Srikanth B. Iyengar, Graham J. Leuschke, Anton Leykin, Claudia Miller, Ezra Miller “Twenty-Four Hours of Local Cohomology"
American Mathematical Society | 2007-12-06 | ISBN: 0821841262 | PDF | 282 pages | 1,7 Mb

This book is aimed to provide an introduction to local cohomology which takes cognizance of the breadth of its interactions with other areas of mathematics. It covers topics such as the number of defining equations of algebraic sets, connectedness properties of algebraic sets, connections to sheaf cohomology and to de Rham cohomology, Gröbner bases in the commutative setting as well as for $D$-modules, the Frobenius morphism and characteristic $p$ methods, finiteness properties of local cohomology modules, semigroup rings and polyhedral geometry, and hypergeometric systems arising from semigroups. The book begins with basic notions in geometry, sheaf theory, and homological algebra leading to the definition and basic properties of local cohomology. Then it develops the theory in a number of different directions, and draws connections with topology, geometry, combinatorics, and algorithmic aspects of the subject.]]> free book city Tue, 29 Apr 2008 10:43:57 +0430
