Synopsis

Random variation over space and time is one of the few attributes that might safely be predicted as characterizing almost any given complex system. Random fields or "distributed disorder systems" confront astronomers, physicists, geologists, meteorologists, biologists, and other natural scientists. They appear in the artifacts developed by electrical, mechanical, civil, and other engineers. They even underlie the processes of social and economic change. The purpose of this book is to bring together existing and new methodologies of random field theory and indicate how they can be applied to these diverse areas where a "deterministic treatment is inefficient and conventional statistics insufficient." Many new results and methods are included.

After outlining the extent and characteristics of the random field approach, the book reviews the classical theory of multidimensional random processes and introduces basic probability concepts and methods in the random field context. It next gives a concise amount of the second-order analysis of homogeneous random fields, in both the space-time domain and the wave number-frequency domain. This is followed by a chapter on spectral moments and related measures of disorder and on level excursions and extremes of Gaussian and related random fields.

After developing a new framework of analysis based on local averages of one-, two-, and n-dimensional processes, the book concludes with a chapter discussing ramifications in the important areas of estimation, prediction, and control. The mathematical prerequisite has been held to basic college-level calculus.

About this title

From the Inside Flap

Random variation is a fact of life that provides substance to a wide range of problems in the sciences, engineering, and economics. There is a growing need in diverse disciplines to model complex patterns of variation and interdependence using random fields, as both deterministic treatment and conventional statistics are often insufficient. An ideal random field model will capture key features of complex random phenomena in terms of a minimum number of physically meaningful and experimentally accessible parameters. This volume, a revised and expanded edition of an acclaimed book first published by the M I T Press, offers a synthesis of methods to describe and analyze and, where appropriate, predict and control random fields. There is much new material, covering both theory and applications, notably on a class of probability distributions derived from quantum mechanics, relevant to stochastic modeling in fields such as cosmology, biology and system reliability, and on discrete-unit or agent-based random processes.

Random Fields is self-contained and unified in presentation. The first edition was found, in a review in EOS (American Geophysical Union) to be "both technically interesting and a pleasure to read ]] the presentation is clear and the book should be useful to almost anyone who uses random processes to solve problems in engineering or science ]] and (there is) continued emphasis on describing the mathematics in physical terms."

Review

"Random Fields is a book which I found both technically interesting and a pleasure to read ... The presentation is clear and the book should be useful to almost anyone who uses random processes to solve problems in engineering or science ... I was particularly impressed with ... the emphasis on utility and the importance of local averages. Chapter 4, 'Spectral Parameters, Level Excursions, and Extremes', is an unusually clear and orderly treatment of these topics. It is also refreshing to read a work on stochastic processes where the author emphasizes that microscopic variations may be of no practical interest to the problem at hand!" ---- David J Thomson, Bell Laboratories, New Jersey, USA, in EOS (American Geophysical Union)

"The author explains in a clear and thorough way the intricacies of random field modeling. Every time I pick up the book, I discover something new and exciting. I especially like its lucid coverage of the effects of local averaging, which provides an excellent basis for describing the world around us." ---- Gordon A Fenton, Professor of Applied Mathematics, Dalhousie University, Canada

"As a researcher of the topic of laser beam propagation through random media for the last 35 years, I'm very familiar with random field theory. Vanmarcke's book on this highly complex topic is written in a way that makes the material very accessible. It is a key reference for my students." ---- Ronald L Phillips, Professor Emeritus, School of Electrical Engineering and Computer Science, University of Central Florida and Kennedy Space Center, Florida, USA
