Hand-based biometrics identifies users by unique features in their hands, such as fingerprints, palmprints, hand geometry, and finger and palm vein patterns. This book explores the range of technologies and methods under development and in use for hand-based biometrics, with evaluations of the advantages and performance of each. The inclusion of significant material on the relevant aspects of the physiology of the hand is a particularly useful and innovative feature.

During the 1980s the worldwide interest in electromagnetic compatibility (EMC) grew rapidly with the introduction of legislation to control the growing interference problems generated by the increased use of electronic equipment in industry and in the home. The European directive harmonising EMC measurements gave particular impetus to manufacturers and importers of electrical and electronic equipment in Europe to understand EMC design techniques and verification procedures. This book explains how equipment can be verified by testing. It discusses the nature of EMC standards world wide and describes in detail testing methods and their conduct and accuracy. In addition to standard EMC testing, topics including electrostatic discharge, nuclear electromagnetic pulse and lightning are also discussed.

In 1918, the U.S. Army Signal Corps sent 223 women to France at General Pershing’s explicit request. They were masters of the latest technology: the telephone switchboard. While suffragettes picketed the White House and President Wilson struggled to persuade a segregationist Congress to give women of all races the vote, these courageous young women swore the army oath and settled into their new roles. Elizabeth Cobbs reveals the challenges they faced in a war zone where male soldiers wooed, mocked, and ultimately celebrated them.

The army discharged the last Hello Girls in 1920, the year Congress ratified the Nineteenth Amendment. When they sailed home, they were unexpectedly dismissed without veterans’ benefits and began a sixty-year battle that a handful of survivors carried to triumph in 1979.

“What an eye-opener! Cobbs unearths the original letters and diaries of these forgotten heroines and weaves them into a fascinating narrative with energy and zest.”
—Cokie Roberts, author of Capital Dames

“This engaging history crackles with admiration for the women who served in the U.S. Army Signal Corps during the First World War, becoming the country’s first female soldiers.”
—New Yorker

“Utterly delightful… Cobbs very adroitly weaves the story of the Signal Corps into that larger story of American women fighting for the right to vote, but it’s the warm, fascinating job she does bringing her cast…to life that gives this book its memorable charisma… This terrific book pays them a long-warranted tribute.”
—Christian Science Monitor

“Cobbs is particularly good at spotlighting how closely the service of military women like the Hello Girls was tied to the success of the suffrage movement.”

A dominating theme of the 21st Century will be the transmission and processing of information as the global network of communication channels continues to develop. The emergence of today's digital communications technology owes much to the growth of telegraphy in the 19th and 20th Centuries. The realisation of cheap long-distance communication using telegraphy stimulated the initial design and development of coded transmissions that proved vital in both World Wars for use on land, sea, and in the air. Methods of data compaction, coding and encryption in modern communication systems all have their origins in the techniques used by the telegraph pioneers. In fact the two main phases of telegraph development - cable-based techniques that began in the early 19th Century and wireless transmission in the 20th Century - parallel the changes in voice and information communications seen recently.

An innovative approach to the relationship between filmmaking and society during Hollywood's golden age. The 1910s and 1920s witnessed the inception of a particular brand of negotiation between filmdom and its public in the United States. Hollywood, its proponents, and its critics sought to establish new connections between audience and industry, suggesting means by which Hollywood outsiders could become insiders. Hollywood Outsiders looks at how four disparate entities--the Palmer Photoplay correspondence school of screenwriting, juvenile series fiction about youngsters involved in the film industry, film appreciation and character education programs for high school students, and Catholic and Protestant efforts to use and influence filmmaking--conceived of these connections, and thus of the relationship of Hollywood to the individual and society. Anne Morey's exploration of the diverse discourses generated by these different conjunctions leads to a fresh and compelling interpretation of Hollywood's place in American cultural history. In its analysis of how four distinct groups, each addressing constituencies of various ages and degrees of social authority, defined their interest in the film industry, Hollywood Outsiders combines concrete discussions of cultural politics with a broader argument about how outsiders viewed the film industry as a vehicle of self-validation and of democratic ideals. Anne Morey is assistant professor of English and performance studies at Texas A&M University.

“So you’re the one getting this gift? Lucky you! Someone who knows you has visited the museum. They searched out things they thought you would care about, and they took photos and left messages for you.” This is the welcoming message for the Gift app, designed to create a very personal museum visit. Hybrid Museum Experiences use new technologies to augment, expand or alter the physical experience of visiting the museum. They are designed to be experienced in close relation to the physical space and exhibit. In this book we discuss three forms of hybridity in museum experiences: incorporating the digital and the physical, creating social, yet personal and intimate experiences, and exploring ways to balance visitor participation and museum curation. The book reports on a three-year cross-disciplinary research project in which artists, design researchers and museum professionals have collaborated to create technology-mediated experiences that merge with the museum environment.
