Jonathan Crary's Techniques of the Observer provides a dramatically new perspective on the visual culture of the nineteenth century, reassessing problems of both visual modernism and social modernity. This analysis of the historical formation of the observer is a compelling account of the prehistory of the society of the spectacle. In Techniques of the Observer Jonathan Crary provides a dramatically new perspective on the visual culture of the nineteenth century, reassessing problems of both visual modernism and social modernity. Inverting conventional approaches, Crary considers the problem of visuality not through the study of art works and images, but by analyzing the historical construction of the observer. He insists that the problems of vision are inseparable from the operation of social power and examines how, beginning in the 1820s, the observer became the site of new discourses and practices that situated vision within the body as a physiological event. Alongside the sudden appearance of physiological optics, Crary points out, theories and models of "subjective vision" were developed that gave the observer a new autonomy and productivity while simultaneously allowing new forms of control and standardization of vision. Crary examines a range of diverse work in philosophy, in the empirical sciences, and in the elements of an emerging mass visual culture. He discusses at length the significance of optical apparatuses such as the stereoscope and of precinematic devices, detailing how they were the product of new physiological knowledge. He also shows how these forms of mass culture, usually labeled as "realist," were in fact based on abstract models of vision, and he suggests that mimetic or perspectival notions of vision and representation were initially abandoned in the first half of the nineteenth century within a variety of powerful institutions and discourses, well before the modernist painting of the 1870s and 1880s.

Reprinted with a new design and a number of never-before-seen images is the famed first monograph of two-time National Endownment for the Arts Fellow, Larry Fink. In an elegant exploration of two distinctly different cultures and classes, Frink captured a sense of stale emptiness lurking in the sensuous decadence of the upper crust of NYC, only to turn the tide and let loose with the often raucous, emotional and intimate photographs of the down-home folk of Martins Creek, Pennsylvania. Illustrated with 92 duotone photos.

In Friedrich Dürrenmatt’s experimental thriller The Assignment, the wife of a psychiatrist has been raped and killed near a desert ruin in North Africa. Her husband hires a woman named F. to reconstruct the unsolved crime in a documentary film. F. is soon unwittingly thrust into a paranoid world of international espionage where everyone is watched—including the watchers. After discovering a recent photograph of the supposed murder victim happily reunited with her husband, F. becomes trapped in an apocalyptic landscape riddled with political intrigue, crimes of mistaken identity, and terrorism. F.’s labyrinthine quest for the truth is Dürrenmatt’s fictionalized warning against the dangers of a technologically advanced society that turns everyday life into one of constant scrutiny. Joel Agee’s elegant translation will introduce a fresh generation of English-speaking readers to one of European literature’s masters of language, suspense, and dystopia. “The narrative is accelerated from the start. . . . As the novella builds to its horripilating climax, we realize the extent to which all values have thereby been inverted. The Assignment is a parable of hell for an age consumed by images.”—New York Times Book Review “His most ambitious book . . . dark and devious . . . almost obsessively drawn to mankind’s most fiendish crimes.”—Chicago Tribune “A tour-de-force . . . mesmerizing.”—Village Voice

The purpose of this fantastically useful book is to lay out an overview on possible tools for state reconstruction in nonlinear systems. Here, basic observability notions and observer structures are recalled, together with ingredients for advanced designs on this basis. The problem of state reconstruction in dynamical systems, known as observer problem, is crucial for controlling or even merely monitoring processes. For linear systems, the theory has been well established for several years, so this book attempts to tackle the problem for non-linear systems.

Observers are digital algorithms that combine sensor outputs with knowledge of the system to provide results superior to traditional structures, which rely wholly on sensors. Observers have been used in selected industries for years, but most books explain them with complex mathematics. Observers in Control Systems uses intuitive discussion, software experiments, and supporting analysis to explain the advantages and disadvantages of observers. If you are working in controls and want to improve your control systems, observers could be the technology you need and this book will give you a clear, thorough explanation of how they work and how to use them. Control systems and devices have become the most essential part of nearly all mechanical systems, machines, devices and manufacturing systems throughout the world. Increasingly the efficiency of production, the reliability of output and increased energy savings are a direct result of the quality and deployment of the control system. A modern and essential tool within the engineer's kit is the Observer which helps improve the performance and reduce the cost of these systems. George Ellis is the author of the highly successful Control System Design Guide (Second Edition). Unlike most controls books, which are written by control theorists and academics, Ellis is a leading engineer, designer, author and lecturer working in industry directly with the users of industrial motion control systems. Observers in Control Systems is written for all professional engineers and is designed to be utilized without an in-depth background in control theory. This is a "real-world" book which will demonstrate how observers work and how they can improve your control system. It also shows how observers operate when conditions are not ideal and teaches the reader how to quickly tune an observer in a working system. Software Available online: A free updated and enhanced version of the author's popular Visual ModelQ allows the reader to practice the concepts with Visual ModelQ models on a PC. Based on a virtual laboratory, all key topics are demonstrated with more than twenty control system models. The models are written in Visual ModelQ ,and are available on the Internet to every reader with a PC. - Teaches observers and Kalman filters from an intuitive perspective - Explains how to reduce control system susceptibility to noise - Shows how to design an adaptive controller based on estimating parameter variation using observers - Shows how to improve a control system's ability to reject disturbances - Key topics are demonstrated with PC-based models of control systems. The models are written in both MatLab® and ModelQ; models are available free of charge

For over a quarter of a century, high-gain observers have been used extensively in the design of output feedback control of nonlinear systems. This book presents a clear, unified treatment of the theory of high-gain observers and their use in feedback control. Also provided is a discussion of the separation principle for nonlinear systems; this differs from other separation results in the literature in that recovery of stability as well as performance of state feedback controllers is given. The author provides a detailed discussion of applications of high-gain observers to adaptive control and regulation problems and recent results on the extended high-gain observers. In addition, the author addresses two challenges that face the implementation of high-gain observers: high dimension and measurement noise. Low-power observers are presented for high-dimensional systems. The effect of measurement noise is characterized and techniques to reduce that effect are presented. The book ends with discussion of digital implementation of the observers. Readers will find comprehensive coverage of the main results on high-gain observers; rigorous, self-contained proofs of all results; and numerous examples that illustrate and provide motivation for the results. The book is intended for engineers and applied mathematicians who design or research feedback control systems.

A critical survey of nine documentary photographers who were at the cutting edge of this form of journalism during the second half of the 20th century, 'Engaged Observers' shows how since the sixties photographers such as Leonard Freed & Susan Meiselas have challenged the conventional objectivity of the newsroom.
