What started out as a minor Project in 1987, blew out like the national debt so with all this accumulated info, it seemed worthwhile to produce the first book, here now is the Latest Online Edition. The sources and references have been many and varied and although the utmost care was taken, the Lists are far from complete and may contain errors. The original Codes etc were designed principally for marine use as this was the field in which radio was initially developed. The majority retain this influence but many have been modified and modernized to cover land and air applications. Technical terms have also varied as technology has changed however most abbreviations of the computer age have been omitted. These are specialist terms of that mode, not often encountered in telegraphy.

This book explores the strikingly similar ways in which information is encoded in nonverbal man-made signals (e.g., traffic lights and tornado sirens) and animal-evolved signals (e.g., color patterns and vocalizations). The book also considers some coding principles for reducing certain unwanted redundancies and explains how desirable redundancies enhance communication reliability. Jack Hailman believes this work pioneers several aspects of analyzing human and animal communication. The book is the first to survey man-made signals as a class. It is also the first to compare such human-devised systems with signaling in animals by showing the highly similar ways in which the two encode information. A third innovation is generalizing principles of quantitative information theory to apply to a broad range of signaling systems. Finally, another first is distinguishing among types of redundancy and their separation into unwanted and desirable categories. This remarkably novel book will be of interest to a wide readership. Appealing not only to specialists in semiotics, animal behavior, psychology, and allied fields but also to general readers, it serves as an introduction to animal signaling and to an important class of human communication.

Pussyhats, typically crafted with yarn, quite literally created a sea of pink the day after Donald J. Trump became the 45th president of the United States in January 2017, as the inaugural Women’s March unfolded throughout the U.S., and sister cities globally. But there was nothing new about women crafting as a means of dissent. Crafting Dissent: Handicraft as Protest from the American Revolution to the Pussyhats is the first book that demonstrates how craft, typically involving the manipulation of yarn, thread and fabric, has also been used as a subversive tool throughout history and up to the present day, to push back against government policy and social norms that crafters perceive to be harmful to them, their bodies, their families, their ideals relating to equality and human rights, and their aspirations. At the heart of the book is an exploration for how craft is used by makers to engage with the rhetoric and policy shaping their country’s public sphere. The book is divided into three sections: "Crafting Histories," Politics of Craft," and "Crafting Cultural Conversations." Three features make this a unique contribution to the field of craft activism and history: The inclusion of diverse contributors from a global perspective (including from England, Ireland, India, New Zealand, Australia) Essay formats including photo essays, personal essays and scholarly investigations The variety of professional backgrounds among the book’s contributors, including academics, museum curators, art therapists, small business owners, provocateurs, artists and makers. This book explains that while handicraft and craft-motivated activism may appear to be all the rage and “of the moment,” a long thread reveals its roots as far back as the founding of American Democracy, and at key turning points throughout the history of nations throughout the world.

Implementing new architectures and designs for the magnetic recording read channel have been pushed to the limits of modern integrated circuit manufacturing technology. This book reviews advanced coding and signal processing techniques and architectures for magnetic recording systems. Beginning with the basic principles, it examines read/write operations, data organization, head positioning, sensing, timing recovery, data detection, and error correction. It also provides an in-depth treatment of all recording channel subsystems inside a read channel and hard disk drive controller. The final section reviews new trends in coding, particularly emerging codes for recording channels.
