This book provides a chronological literature review of optical wireless communication, followed by a detailed blueprint of a visible light communication (VLC) setup with the key characteristics of LEDs and photodetectors. Next, the optical channel impulse response and its description for different possible topologies is presented together with a description of the optical and electrical setup for both optical transmitters (oTx) and optical receivers (oRx). Different single carrier and multi-carrier modulations particularly applied in visible light communication setups are also presented. Both the optical and electrical modules of oTx and oRx are simulated and then prototyped and tested as embedded devices in an underground positioning and monitoring system for a continuous real time identification of the personnel on the main underground galleries where the illumination network is already installed. Presents a comprehensive look at visible light communication technology, both in description and application; Shows where and how VLC has been launched on the market as an alternative or partner technology to the existing wireless communication technologies based on radio frequency; Includes special focus on underground positioning and monitoring with embedded VLC.
Timely and pathbreaking, Securing the Peace is the first book to explore the complete spectrum of civil war terminations, including negotiated settlements, military victories by governments and rebels, and stalemates and ceasefires. Examining the outcomes of all civil war terminations since 1940, Monica Toft develops a general theory of postwar stability, showing how third-party guarantees may not be the best option. She demonstrates that thorough security-sector reform plays a critical role in establishing peace over the long term. Much of the thinking in this area has centered on third parties presiding over the maintenance of negotiated settlements, but the problem with this focus is that fewer than a quarter of recent civil wars have ended this way. Furthermore, these settlements have been precarious, often resulting in a recurrence of war. Toft finds that military victory, especially victory by rebels, lends itself to a more durable peace. She argues for the importance of the security sector--the police and military--and explains that victories are more stable when governments can maintain order. Toft presents statistical evaluations and in-depth case studies that include El Salvador, Sudan, and Uganda to reveal that where the security sector remains robust, stability and democracy are likely to follow. An original and thoughtful reassessment of civil war terminations, Securing the Peace will interest all those concerned about resolving our world's most pressing conflicts.
The Foreign Relations of the United States series presents the official documentary historical record of major foreign policy decisions and significant diplomatic activity of the United States Government. Part of a subseries of the State Department's Foreign Relations of the United States (FRUS) series that documents the most important issues in the foreign policy of the administrations of Richard M. Nixon and Gerald R. Ford, this volume documents U.S. policy towards Iran and Iraq from 1973 to 1976. The volume's six chapters are divided into two chronological sections. The first section documents the increasingly close political, economic, and strategic relationship, which developed between the U.S. and Iran during the mid-1970s. The second section covers Washington's somewhat more distant interactions with Iraq, with whom the United States did not maintain formal diplomatic relations following the 1967 Arab-Israeli war. Historians, researchers, and students in high school and above, including debate teams, may want to use this resource for the chronological timeframes for U.S. involvement with Iran druing the mid-1970s. High school, public, community college, and academic/university libraries will want to include this primary source reference work in their Middle East reference collections.

What is women's empowerment, and how and why does it matter for women's health? Despite the rise of a human rights-based approach to women's health and increasing awareness of the synergies between women's health and empowerment, a lack of consensus remains as to how to measure empowerment and successfully intervene in ways that improve health. Women's Empowerment and Global Health provides thirteen detailed, multidisciplinary case studies from across the globe and through the course of a woman's life to show how science and advocacy can be creatively merged to enhance the agency and status of women. Accompanying short videos provide background about programs on the ground in India, the United States, Mexico, Nicaragua, Zimbabwe, and South Africa. Women's Empowerment and Global Health explores the promises and limits of programmatic, scientific, and rights-based work in real-world settings and provides the next generation of researchers and practitioners, as well as students in global and public health, sociology, anthropology, women's studies, law, business, and medicine, with cutting edge and inspirational examples of programs that point the way toward achieving women's equality and fulfilling the right to health."--Provided by publisher.
