Time series with mixed spectra are characterized by hidden periodic components buried in random noise. Despite strong interest in the statistical and signal processing communities, no book offers a comprehensive and up-to-date treatment of the subject. Filling this void, Time Series with Mixed Spectra focuses on the methods and theory for the statistical analysis of time series with mixed spectra. It presents detailed theoretical and empirical analyses of important methods and algorithms. Using both simulated and real-world data to illustrate the analyses, the book discusses periodogram analysis, autoregression, maximum likelihood, and covariance analysis. It considers real- and complex-valued time series, with and without the Gaussian assumption. The author also includes the most recent results on the Laplace and quantile periodograms as extensions of the traditional periodogram. Complete in breadth and depth, this book explains how to perform the spectral analysis of time series data to detect and estimate the hidden periodicities represented by the sinusoidal functions. The book not only extends results from the existing literature but also contains original material, including the asymptotic theory for closely spaced frequencies and the proof of asymptotic normality of the nonlinear least-absolute-deviations frequency estimator.

CoCo: The Colorful History of Tandy's Underdog Computer is the first book to document the complete history of the Tandy Color Computer (CoCo), a popular 8-bit PC series from the 1980s that competed against the era's biggest names, including the Apple II, IBM PC, and Commodore 64. The book takes you inside the interesting stories and people behind this unique, underdog computer. Both noted computer science and technology advocates, authors Pitre and Loguidice reveal the story of a pivotal period in the home computing revolution from the perspective of Tandy's CoCo. As these computers were sold in Radio Shack stores throughout the United States and other countries, they provide a critical point of reference for key events in the unprecedented evolutionary period for the PC industry in the 1980s. The book also features first-hand accounts from the people who created and promoted the CoCo, from the original Tandy executives and engineers to today's active product creators and information keepers. The CoCo impacted many lives, and this book leaves no stone unturned in recounting this fascinating slice of the PC revolution that is still in play today. From early telecommunications experiments to engineering and budgetary challenges, it covers all the aspects that made the CoCo a truly personal, useful computing experience in as small and inexpensive a package as possible.

Microcomputers are an increasingly important tool in all aspects of development as the need to handle and assimilate vast quantities of information becomes ever more critical for both the international development community and the developing countries. In addition, the microcomputer represents the first significant technological advance that a developing country can assimilate and exploit with a relatively low capital investment and without prior knowledge or involvement in other technologies. Unfortunately this new technology represents not only an opportunity if properly exploited but a threat if ignored. The widespread and increasing incorporation of microcomputers into all aspects of the developed countries represents a major technological advance and an inevitable social change. If a developing country fails to take advantage of the opportunity that microcomputer technology represents, its level of development in relation to developed countries will be significantly lowered. Organized by the Board on Science and Technology for International Development in response to a request from the U.S. Agency for International Development, this book is an overview of microcomputer applications in developing countries and the issues associated with their use and abuse. The first section of the book is an assessment of the need for microcomputers in development. Written primarily for those in the development field and other computer-literate individuals, the second part is divided into applications in agriculture, health, energy, and municipal management. Policy concerns are addressed in the final section. It discusses the technology transfer that takes place as countries try to establish national computer policies that meet local needs while encouraging creative and useful applications.

Have we resigned ourselves to a cyber-future that has been decided behind our backs? Why is technology - and our understanding of it - central to the concerns of critical social theory? In developing the PC technologists have borrowed ideas from the human sciences about what people are like, about the nature of meaning and the desirability of some experiences over others. Yet, to date, the academic disciplines most concerned with these ideas have offered neither resistance nor debate. In this book, Graeme Kirkpatrick shows why it is crucial that we initiate that debate. Offering a revealing critique of PC design and the social assumptions that underlie it, Kirkpatrick argues that it relies on a particular conception of a capitalistic society that expects its technology to come pre-packaged, mass-marketed and "user-friendly". Anyone who is critical of such a society and its commodification of human achievement should, he suggests, be suspicious. Kirkpatrick argues that the computer is a contested space within which major social conflicts are played out. On the one hand, there is a narrative of flexibility and human empowerment, and on the other a sense of a "system" that controls our lives, leaving us in thrall to the computer corporations, and at constant risk from phishers and hackers. The outcomes of these conflicts are extremely important as they will shape our future experience of technology, society and politics. Critical Technology is a lively, provocative and often radical book, which forces us to reflect on the meaning of an artefact that is central to our daily lives, yet that we too often take for granted.

This second edition of Compact Numerical Methods for Computers presents reliable yet compact algorithms for computational problems. As in the previous edition, the author considers specific mathematical problems of wide applicability, develops approaches to a solution and the consequent algorithm, and provides the program steps. He emphasizes useful applicable methods from various scientific research fields, ranging from mathematical physics to commodity production modeling. While the ubiquitous personal computer is the particular focus, the methods have been implemented on computers as small as a programmable pocket calculator and as large as a highly parallel supercomputer. New to the Second Edition Presents program steps as Turbo Pascal code Includes more algorithmic examples Contains an extended bibliography The accompanying software (available by coupon at no charge) includes not only the algorithm source codes, but also driver programs, example data, and several utility codes to help in the software engineering of end-user programs. The codes are designed for rapid implementation and reliable use in a wide variety of computing environments. Scientists, statisticians, engineers, and economists who prepare/modify programs for use in their work will find this resource invaluable. Moreover, since little previous training in numerical analysis is required, the book can also be used as a supplementary text for courses on numerical methods and mathematical software.
