During the Vietnam War, the U.S. Army deployed electronic sensors along the Ho Chi Minh Trail in Laos, Cambodia, North Vietnam, and South Vietnam in order to detect and track troop and vehicle movements. At approximately 8,100 miles in length, monitoring this sophisticated logistics network_consisting of roads, trails, vehicle parks, petroleum pipelines, and storage areas_was no mean task. Since the work was classified as 'Secret' until only recently, a comprehensive story of the electronic sensors used in Southeast Asia has never been completely told. Wiring Vietnam: The Electronic Wall relates the history of the electronic detection system that was deployed during the Vietnam War. Author Anthony Tambini covers everything from the sensors used to detect seismic signals from nearby troop and vehicle movements to audio sensors that were deployed to pick up conversations of troops as well as traffic noise of vehicles to engine ignition detectors. Beginning with the conception, development, and implementation of these sensors, Tambini then relates how, ultimately, the various signals the sensors collected were transmitted to orbiting aircraft that would process and retransmit the signals onward to a base in Thailand. There the data underwent further analysis for possible targets that could be attacked from the air. Anthony Tambini, a member of the 25th Tactical Fighter Squadron based at Ubon, Thailand in the late 1960s, was part of an organization that dropped these sensors. His firsthand perspective, along with rarely seen photographs of the actual sensors used, will provide those interested in the Vietnam War and modern warfare with a clear picture of an undocumented side of history.

This book outlines issues related to massive integration of electric and plug-in hybrid electric vehicles into power grids. Electricity is becoming the preferred energy vector for the next new generation of road vehicles. It is widely acknowledged that road vehicles based on full electric or hybrid drives can mitigate problems related to fossil fuel dependence. This book explains the emerging and understanding of storage systems for electric and plug-in hybrid vehicles. The recharging stations for these types of vehicles might represent a great advantage for the electric grid by facilitating integration of renewable and distributed energy production. This book presents a broad review from analyzing current literature to on-going research projects about the new power technologies related to the various charging architectures for electric and plug-in hybrid vehicles. Specifically focusing on DC fast charging operations, as well as, grid-connected power converters and the full range of energy storage systems. These key components are analyzed for distributed generation and charging system integration into micro-grids. The authors demonstrate that these storage systems represent effective interfaces for the control and management of renewable and sustainable distributed energy resources. New standards and applications are emerging from micro-grid pilot projects around the world and case studies demonstrate the convenience and feasibility of distributed energy management. The material in this unique volume discusses potential avenues for further research toward achieving more reliable, more secure and cleaner energy.
