Book Description
Television in the Antenna Age is a brief, accessible, and engaging overview of the medium’s history and development in the US. Integrating three major concerns--television as an industry, a technology, and an art—the book is a basic primer on the complex, fascinating, and often overlooked story of television and its impact on American life. Covers the entire history of American television, from its urban, middle-class beginnings in the late 40s, to the contemporary impact of new technologies and consolidated corporate. Includes interview segments with industry insiders, pictures, and sidebars to illustrate important figures, trends, and events

Book Description
Frequently it is suggested that the ‘golden age' of television was during the period 1950-1960. It is true that television almost ruined Hollywood's fortunes during this period. But if this was the authentic golden age, then it was an age of black and white, somewhat limited creativity, poor reception, lack of competition (except in the United States) and – by and large – public service broadcasting. However, if we take 1950 as a generic ‘starting point' for modern television broadcasting, then we talk about a kind of prehistoric stage of the medium – in which it remained for the best part of three decades. The younger days of broadcasting were the 1980s; the time when commercial television started on a large scale and, in this youth, was getting younger in terms of programming. Luxembourg-based SES Astra appeared on the scene at exactly this time. Astra was instrumental in the dramatic developments in television that we have witnessed since then. This is the story we want to tell in this book. Without satellite technology and the success of satellite reception, without the resulting mass-market penetration of television sets and general economic prosperity we would not have the necessary base ingredients to make the great leap forward into digital, into HDTV, 3D-television, and the prospects of Ultra High Definition now in sight.

Book Description
Joe Carr has provided radio amateurs and short-wave listeners with the definitive design guide for sending and receiving radio signals with Antenna Toolkit 2nd edition.Together with the powerful suite of CD software, the reader will have a complete solution for constructing or using an antenna - bar the actual hardware! The software provides a simple Windows-based aid to carrying out the design calculations at the heart of successful antenna design. All the user needs to do is select the antenna type and set the frequency - a much more fun and less error prone method than using a conventional calculator to solve formulae. The new edition has been revised to include further cases of propagation, additional antennas and also two new chapters - Small Loop Antennas (a topic of considerable interest, which has been the subject of much recent debate in the amateur radio press); and Yagi Beam Antennas (widely used at HF and VHF). The CD software has also been updated.Joe Carr's expertise in the area of antenna design is legendary. Antenna designers, whether hobbyist or technician, can be assured they need look no further than Antenna Toolkit for the complete guide to understanding the practicalities of using and designing antennas today.A complete solution for antenna design in one package.Includes free CD-ROM with state of the art software for all design calculations.The definitive guide to antenna design for radio amateurs and short-wave listeners.

Book Description
Digital Currents explores the growing impact of digital technologies on aesthetic experience and examines the major changes taking place in the role of the artist as social communicator. Margot Lovejoy recounts the early histories of electronic media for art making - video, computer, the internet - in this richly illustrated book. She provides a context for the works of major artists in each media, describes their projects, and discusses the issues and theoretical implications of each to create a foundation for understanding this developing field. Digital Currents fills a major gap in our understanding of the relationship between art and technology, and the exciting new cultural conditions we are experiencing. It will be ideal reading for students taking courses in digital art, and also for anyone seeking to understand these new creative forms.

Book Description
Environmental Health: Ecological Perspectives is intended as an environmental health text for both undergraduate and graduate levels. This text provides balanced coverage of how humans are affected by the quality of air, water, and food as well as how humans affect these survival necessities. The evolution and prosperity of the human species has resulted in concerns about pollution, overpopulation, and several other issues that are having a harmful effect on humans and our environment. This knowledge, along with an understanding of the legislation and history of environmental issues, will help students to make positive changes in their behavior and in the world around them.

Book Description
This practical resource provides a current and comprehensive treatment of GPS/GNSS antennas, taking into account modernized systems and new and developing applications. The book presents a number of key applications, describing corresponding receiver architectures and antenna details. You find important discussions on antenna characteristics, including theory of operation, gain, bandwidth, polarization, phase center, mutual coupling effects, and integration with active components. Moreover, you get expert guidance on the design of adaptive arrays and signal processing techniques used to mitigate interference such as jamming. Addressing critical GNSS antenna high precision requirements, this in-depth book explains the relationships between antenna gain, satellite visibility, geometric dilution of precision, and the carrier-to-noise density ratio. The book delineates requirements for both dual-band and tri-band antennas. You get detailed coverage of a wide range of antenna designs, including microstrip patch, quadrafilar helix, axial mode helix, spiral, inverted L, and planar inverted F antennas. Moreover, you find a discussion on new magnetic metamaterialù substrates and other dielectric substrate materials. Further, this comprehensive book presents designs for very compact GNSS antennas for personal handheld devices and automobiles.
