“Big data” refers to our burgeoning ability to crunch vast collections of information, analyze it instantly, and draw sometimes profoundly surprising conclusions from it. This emerging science can translate myriad phenomena—from the price of airline tickets to the text of millions of books—into searchable form, and uses our increasing computing power to unearth epiphanies that we never could have seen before. A revolution on par with the Internet or perhaps even the printing press, big data will change the way we think about business, health, politics, education, and innovation in the years to come. It also poses fresh threats, from the inevitable end of privacy as we know it to the prospect of being penalized for things we haven’t even done yet, based on big data’s ability to predict our future behavior.In this brilliantly clear, often surprising work, two leading experts explain what big data is, how it will change our lives, and what we can do to protect ourselves from its hazards. Big Data is the first big book about the next big thing.www.big-data-book.com

    The constituent technologies discussed comprise neural networks, fuzzy logic, genetic algorithms, and a number of hybrid systems which include classes such as neuro-fuzzy, fuzzy-genetic, and neuro-genetic systems. The hybridization of the technologies is demonstrated on architectures such as Fuzzy-Back-propagation Networks (NN-FL), Simplified Fuzzy ARTMAP (NN-FL), and Fuzzy Associative Memories. The book also gives an exhaustive discussion of FL-GA hybridization. This book with a wealth of information that is clearly presented and illustrated by many examples and applications is designed for use as a text for courses in soft computing at both the senior undergraduate and first-year postgraduate engineering levels.

    This volume answers questions such as: Should I use low- or high-flanged hubs for touring * Should I spoke crossed-four or crossed-three? Are radially spoked wheels stiffer than crossed-four? * How can I build a 32-spoke crossed-two wheel? * Should I use butted or straight sookes? * Does tying and soldering give a rough ride?Based on years of experience, the author has divided the book into three parts. Part One, Theory, explains how wheels respond to loads. It discusses the merits of various designs and components, and explains what causes failures. Part Two, Practice, gives a step-by-step guide for building front and rear wheels and wheels with different patterns and numbers of spokes. Part Three, Data, contains test results and formulas for computing spoke lengths and other wheel dimensions.
