This book explores the growing importance of prisons, both lay and ecclesiastical, in western Europe between 1000 and 1300. It attempts to explain what captors hoped to achieve by restricting the liberty of others, the means of confinement available to them, and why there was an increasingly close link between captivity and suspected criminal activity. It discusses conditions within prisons, the means of release open to some captives, and writing in or about prison.

If you've been searching for a way to get up to speed on IEEE 802.11n and 802.11ac WLAN standards without having to wade through the entire specification, then look no further. This comprehensive overview describes the underlying principles, implementation details and key enhancing features of 802.11n and 802.11ac. For many of these features the authors outline the motivation and history behind their adoption into the standard. A detailed discussion of key throughput, robustness, and reliability enhancing features (such as MIMO, multi-user MIMO, 40/80/160 MHz channels, transmit beamforming and packet aggregation) is given, plus clear summaries of issues surrounding legacy interoperability and coexistence. Now updated and significantly revised, this 2nd edition contains new material on 802.11ac throughput, including revised chapters on MAC and interoperability, plus new chapters on 802.11ac PHY and multi-user MIMO. An ideal reference for designers of WLAN equipment, network managers, and researchers in the field of wireless communications.

On November 15, 1980, two young homebrewers opened a microbrewery in northern California, naming it after a nearby mountain range. Thirty years later, Sierra Nevada Brewing Co. is widely recognized as a leader of the craft brewing revolution that has changed American beer's reputation around the world. Rob Burton, professor of English at California State University, Chico, tells the story of the company's astonishing rise to success.
