Wireless Traffic Steering For Green Cellular Networks
by Shan Zhang Ning Zhang Sheng Zhou Zhisheng Niu Xuemin Sherman ShenThis book introduces wireless traffic steering as a paradigm to realize green communication in multi-tier heterogeneous cellular networks. By matching network resources and dynamic mobile traffic demand, traffic steering helps to reduce on-grid power consumption with on-demand services provided. This book reviews existing solutions from the perspectives of energy consumption reduction and renewable energy harvesting. Specifically, it explains how traffic steering can improve energy efficiency through intelligent traffic-resource matching. Several promising traffic steering approaches for dynamic network planning and renewable energy demand-supply balancing are discussed. This book presents an energy-aware traffic steering method for networks with energy harvesting, which optimizes the traffic allocated to each cell based on the renewable energy status. Renewable energy demand-supply balancing is a key factor in energy dynamics, aimed at enhancing renewable energy sustainability to reduce on-grid energy consumption. Dynamic network planning adjusts cell density with traffic variations to provide on-demand service, which reduces network power consumption with quality of service provisioning during off-peak hours. With intra- or inter-tier traffic steering, cell density is dynamically optimized with regards to the instant traffic load for conventional homogeneous and multi-tier heterogeneous cellular networks, respectively. This book is beneficial for researchers and graduate students interested in traffic management and future wireless networking.

Wirelessly Powered Sensor Networks and Computational RFID
by Joshua R. SmithThe Wireless Identification and Sensing Platform (WISP) is the first of a new class of RF-powered sensing and computing systems. Rather than being powered by batteries, these sensor systems are powered by radio waves that are either deliberately broadcast or ambient. Enabled by ongoing exponential improvements in the energy efficiency of microelectronics, RF-powered sensing and computing is rapidly moving along a trajectory from impossible (in the recent past), to feasible (today), toward practical and commonplace (in the near future). This book is a collection of key papers on RF-powered sensing and computing systems including the WISP. Several of the papers grew out of the WISP Challenge, a program in which Intel Corporation donated WISPs to academic applicants who proposed compelling WISP-based projects. The book also includes papers presented at the first WISP Summit, a workshop held in Berkeley, CA in association with the ACM Sensys conference, as well as other relevant papers. The book provides a window into the fascinating new world of wirelessly powered sensing and computing.
Wiring the World: The Social and Cultural Creation of Global Telegraph Networks (Columbia Studies in International and Global History)
by Simone MüllerThe successful laying of a transatlantic cable in 1866 remade world communications. A message could travel across the ocean in minutes, shrinking the space between continents, cultures, and nations. An eclectic group of engineers, entrepreneurs, politicians, and media visionaries then developed this technology into a telecommunications system that spread a particular vision of civilization—but not everyone wanted to wire the world the same way. Wiring the World is a cultural and social history that explores how the large Anglo-American cable companies won out over alternative visions. Bitter rivalries emerged over telegram prices, visions for world peace, scientific innovation, and the role of the nation-state. Such struggles determined the growth of cable technology, which in turn influenced world history. Filled with fascinating characters and new insights into pivotal events, Wiring the World traces globalization's diverse paths and close ties to business and politics.

Wissenschaftskommunikation, neu sortiert: Eine Systematisierung der externen Kommunikationen der Wissenschaft
by Peer PasternackDer Ausgangspunkt dieser Neusortierung ist: Wissenschaftskommunikation ist die Kontaktaufnahme und -pflege der Wissenschaft mit der Nichtwissenschaft, also mit ihrer Umwelt. Damit wird das Verständnis von Wissenschaftskommunikation sowohl eingeschränkt als auch erweitert: eingeschränkt auf die externe Kommunikation der Wissenschaft, erweitert auf jegliche Kontaktaufnahmen und -pflege der Wissenschaft mit der Nichtwissenschaft.Es zeigt sich, dass es sehr viel mehr Wissenschaftskommunikation gibt, als man gemeinhin denkt, darunter zahlreiche Varianten, die noch gar nicht als Wissenschaftskommunikation erkannt werden. Zugleich zeigt sich: Gemessen an der Verarbeitbarkeit der Angebote findet zu viel Wissenschaftskommunikation statt, und gemessen an der Wirksamkeit der Angebote findet zu wenig effektive, d. h. zielerreichende Wissenschaftskommunikation statt. Um das zu ändern, bedarf es eines deutlichen Bildes davon, was Wissenschaftskommunikation ist, wie sie von anderen Kommunikationen abgegrenzt ist und wie sie intern differenziert ist. Dieses Bild wird hier gezeichnet.
With the Beatles
by Lewis LaphamHalfway between the summer of love and the Tet offensive, the Beatles went to India to study with the Maharishi--and Lewis Lapham, esteemed Harper's editor and award-winning writer, was there. WITH THE BEATLES is a remarkable book of cultural commentary on that seminal '60s moment.The ashram in Rishikesh, India was the ultimate '60s scene: the Beatles, Donovan, Mia Farrow, a stray Beach Boy and other '60s icons gathered along the shores of the Ganges--amidst paisley and incense and flowers and guitars--to meditate at the feet of the Maharishi Mahesh Yogi. The February 1968 gathering received such frenzied, world-wide attention that it is still considered a significant, early encounter between Western pop culture and the mystical East. And Lewis Lapham was the only journalist allowed inside.And what went on inside the compound has long been the subject of wild speculation and rampant rumor. The Beatles said they wrote some of their greatest songs there . . . and yet they also came away bitterly disillusioned. In WITH THE BEATLES, Lewis Lapham finally tells the whole story.
Within the Veil: Black Journalists, White Media
by Pamela NewkirkWinner of the National Press Club Prize for Media CriticismUnmasks race-related conflicts in the newsrooms and the push for more equitable coverage of racial minorities Thirty years ago, the Kerner Commission Report made national headlines by exposing the consistently biased coverage afforded African Americans in the mainstream media. While the report acted as a much ballyhooed wake-up call, the problems it identified have stubbornly persisted, despite the infusion of black and other racial minority journalists into the newsroom. In Within the Veil, Pamela Newkirk unmasks the ways in which race continues to influence reportage, both overtly and covertly. Newkirk charts a series of race-related conflicts at news organizations across the country, illustrating how African American journalists have influenced and been denied influence to the content, presentation, and very nature of news. Through anecdotes culled from interviews with over 100 broadcast and print journalists, Newkirk exposes the trials and triumphs of African American journalists as they struggle in pursuit of more equitable coverage of racial minorities. She illuminates the agonizing dilemmas they face when writing stories critical of blacks, stories which force them to choose between journalistic integrity, their own advancement, and the almost certain enmity of the black community.Within the Veil is a gripping front-line report on the continuing battle to integrate America's newsrooms and news coverage.Companion website: http://www.nyupress.nyu.edu/authors/veil.html
Without a Trace: The Life of Sierra Phantom

Without a Trace drops readers into the California mountain town of Bishop alongside the man locals call Sierra Phantom just as he surrenders to life with an address, and searches for a renewed purpose and community with which to share it.
Without Compromise: The Brave Journalism that First Exposed Donald Trump, Rudy Giuliani, and the American Epidemic of Corruption
by Wayne BarrettA collection of groundbreaking investigations by Wayne Barrett, the intrepid, muckraking Village Voice journalist who exposed corruption in New York City and beyond.With piercing moral clarity and exacting rigor, Wayne Barrett tracked political corruption in the pages of the Village Voice fact by fact, document by document for 40 years. The first to report on the scams and crooked deals that fueled the rise of Donald Trump in 1979, Barrett went on to expose the shady dealings of small-time slum lords and powerful New York City politicians alike, from Ed Koch to Rudy Giuliani to Michael Bloomberg.Without Compromise is the first anthology of Barrett's investigative work, accompanied by essays from colleagues and those he trained. In an age of lies, fog, and propaganda, when the profession of journalism is degraded by the White House and the industry is under financial threat, Barrett reminds us that facts, when clearly accumulated, are our best defense of democracy.Featuring essays by:Joe ConasonKim Phillips-FeinErrol LouisGerson BorreroTom RobbinsTracie McMillanPeter NoelAdam FifieldJarrett MurphyAndrea BernsteinJennifer GonnermanMac Barrett
