Book Description
The full history of St. Patrick's day is captured here for the first time in The Wearing of the Green. Illustrated with photos, the book spans the medieval origins, steeped in folklore and myth, through its turbulent and troubled times when it acted as fuel for fierce political argument, and tells the fascinating story of how the celebration of 17th March was transformed from a stuffy dinner for Ireland's elite to one of the world's most public festivals. Looking at more general Irish traditions and Irish communities throughout the world, Mike Cronin and Daryl Adair follow the history of this widely celebrated event, examining how the day has been exploited both politically and commercially, and they explore the shared heritage of the Irish through the development of this unique patriotic holiday. Highly informative for students of history, cultural studies and sociology, and an absolute delight for anyone interested in the fascinating and unique culture of Ireland.

Book Description
Telecommunication systems and human-machine interfaces have begun using multiple microphones and loudspeakers to render interaction more lifelike, and more efficient. This raises acoustic signal processing problems under multiple-input multiple-output (MIMO) scenarios, encompassing distant speech acquisition, sound source localization and tracking, echo and noise control, source separation and speech dereverberation, and many others. The book opens with an acoustic MIMO paradigm, establishing fundamentals, and linking acoustic MIMO signal processing with classical signal processing and communication theories. The second part of the book presents a novel analysis of acoustic applications carried out in the paradigm to reinforce the fundamentals of acoustic MIMO signal processing.
