TV White Space Spectrum Technologies: Regulations, Standards, and Applications
by Rashid A. Saeed Stephen J. ShellhammerAlthough sophisticated wireless radio technologies make it possible for unlicensed wireless devices to take advantage of un-used broadcast TV spectra, those looking to advance the field have lacked a book that covers cognitive radio in TV white spaces (TVWS). Filling this need, TV White Space Spectrum Technologies: Regulations, Standards and Applic
The TVA Regional Planning and Development Program: The Transformation of an Institution and Its Mission (Urban Planning and Environment)
by David A. JohnsonThe Tennessee Valley Authority (TVA) is a world-renowned model for regional planning and development. Based along the Tennessee River and its series of hydro-electric power stations, dams and reservoirs, the TVA development program envisioned a broad regional planning program. The program focused on development opportunities and problems around the array of TVA dams and their reservoirs. It also created new 'model' towns and pioneered land-use planning bringing together federal, state, and local agencies, farmers, foresters and industrial firms to further the economic, social, and physical conditions of what had been one of the most seriously lagging regions of the U.S. This book is based on the memoirs and experiences of Aelred J. Gray, former planner with the TVA, who saw the 'big picture' and introduced much of the pioneering work of the agency. Gray worked as a staff planner at the TVA for nearly 40 years including a decade as its chief planner, overseeing numerous changes and developments to the Authority's program. As well as building up the regional industrial development and the foundation of state parks, he also had a strong interest in the region's cities. In the 1950s he introduced TVA's landmark Flood Prevention Program, which became a national model. His review of how this innovative and influential regional development agency functioned and changed through the decades will be of value to all those interested in planning practice, planning history, and regional politics.

Twelve Lectures on Structural Dynamics
by André PreumontThis text addresses the modeling of vibrating systems with the perspective of finding the model of minimum complexity which accounts for the physics of the phenomena at play. The first half of the book (Ch.1-6) deals with the dynamics of discrete and continuous mechanical systems; the classical approach emphasizes the use of Lagrange's equations. The second half of the book (Ch.7-12) deals with more advanced topics, rarely encountered in the existing literature: seismic excitation, random vibration (including fatigue), rotor dynamics, vibration isolation and dynamic vibration absorbers; the final chapter is an introduction to active control of vibrations. The first part of this text may be used as a one semester course for 3rd year students in Mechanical, Aerospace or Civil Engineering. The second part of the text is intended for graduate classes. A set of problems is provided at the end of every chapter. The author has a 35 years experience in various aspects of Structural dynamics, both in industry (nuclear and aerospace) and in academia; he was one of the pioneers in the field of active structures. He is the author of several books on random vibration, active structures and structural control.
Twentieth Century Limited: Industrial Design in America, 1925-1939, Second Edition
by Meikle Jeffrey L.In the late 1920's "streamlined" became the term businessmen used to describe new models that were easier to produce as well as those that met with less sales resistance than older products. Illustrating this concept with streamlined objects from soup cans to the Chrysler building, Jeffrey Meikle's classic book, Twentieth Century Limited, celebrates the birth of the industrial design profession from 1925-1939. This second edition includes a new preface and improved photographic reproduction. Commercial artists who answered the call of business -- Walter Dorwin Teague, Norman Bel Geddes, Henry Dreyfuss, and Raymond Loewy the best known among them -- were pioneers who envisioned a coherent machine-age environment in which life would be clean, efficient, and harmonious. Working with new materials -- chrome, stainless steel, Bakelite plastic -- they created a streamlined expressionist style which reflected the desire of the Depression-era public for a frictionless, static society. Appliances such as Loewy's Coldspot refrigerator "set a new standard" (according to the advertisements), and its usefulness extended to the way it improved the middle-class consumer's taste for sleek new products. Profusely illustrated with 150 photographs, Twentieth Century Limited pays tribute to the industrial designers and the way they transformed American culture; a generation after its initial publication, this book remains the best introduction to the subject. The new edition will fascinate anyone interested in art, architecture, technology, and American culture of the 1930's.

The Twenty-First Century Commercial Space Imperative
by Anthony YoungYoung addresses the impressive expansion across existing and developing commercial space business markets, with multiple private companies competing in the payload launch services sector. The author pinpoints the new markets, technologies, and players in the industry, as well as highlighting the overall reasons why it is important for us to develop space. NASA now relies on commercial partners to supply cargo and crew spacecraft and services to and from the International Space Station. The sizes of satellites are diminishing and their capabilities expanding, while costs to orbit are decreasing. Suborbital space tourism holds the potential of new industries and jobs. Commercial space exploration of the Moon and the planets also holds promise. All this activity is a catalyst for anyone interested in joining the developing space industry, from students and researchers to engineers and entrepreneurs. As more and more satellites and rockets are launched and the business of space is expanding at a significant pace, it is increasingly important for scientists and engineers of many disciplines to understand how the business evolved and where it is continuing to develop. The growing field is fully explored in this concise overview to the players in this changing landscape.
Twenty-First Century Estate Agency
by Graham NorwoodThis book is a must have for those estate agents who want to work more effectively in order to grow their business and profits. With 12,000 separately owned estate agencies in the UK this book illustrates how new technology and working practices can revolutionise the industry. Technology can help to improve the competitiveness and sometimes-tarnished image of estate agents in the eyes of the general public. The book contains case studies from international markets and shows how competitive the industry is and how each competitor needs to adopt new approaches to outwit rivals – and to reassure an increasingly sceptical public that agents are worth using, add value and earn their commission.
The Twenty-First Century Mechanistic Theory of Human Cognition: A Critical Analysis (Cognitive Systems Monographs #41)
by Diego Azevedo LeiteThis book presents a theoretical critical appraisal of the Mechanistic Theory of Human Cognition (MTHC), which is one of the most popular major theories in the contemporary field of cognitive science. It analyses and evaluates whether MTHC provides a unifying account of human cognition and its explanation. The book presents a systematic investigation of the internal and external consistency of the theory, as well as a systematic comparison with other contemporary major theories in the field. In this sense, it provides a fresh look at more recent major theoretical debates in this area of scientific research and a rigorous analysis of one of its most central major theories. Rigorous theoretical work is integrated with objective consideration of relevant empirical evidence, making the discussions robust and clear. As a result, the book shows that MTHC provides a significant theoretical contribution for the field of cognitive science. The content is useful for those interested in theoretical and empirical issues concerning major theories in the contemporary field of cognitive science.
Twenty-First Century Military Innovation: Technological, Organizational, and Strategic Change beyond Conventional War
by Marcus SchulzkeContemporary war is as much a quest for decisive technological, organizational, and doctrinal superiority before the fighting starts as it is an effort to destroy enemy militaries during battle. Armed forces that are not actively fighting are instead actively reengineering themselves for success in the next fight and imagining what that next fight may look like. Twenty-First Century Military Innovation outlines the most theoretically important themes in contemporary warfare, especially as these appear in distinctive innovations that signal changes in states’ warfighting capacities and their political goals. Marcus Schulzke examines eight case studies that illustrate the overall direction of military innovation and important underlying themes. He devotes three chapters to new weapons technologies (drones, cyberweapons, and nonlethal weapons), two chapters to changes in the composition of state military forces (private military contractors and special operations forces), and three chapters to strategic and tactical changes (targeted killing, population-centric counterinsurgency, and degradation). Each case study includes an accessible introduction to the topic area, an overview of the ongoing scholarly debates surrounding that topic, and the most important theoretical implications. An engaging overview of the themes that emerge with military innovation, this book will also attract readers interested in particular topic areas.

Twin Tracks: The Unexpected Origins of the Modern World
by James BurkeTwin Tracks is a landmark book of real-world stories that investigates the nature of change and divines as never before the unlikely origins of many aspects of contemporary life. In each of the work's twenty-five narratives, we discover how the different outcomes of an important historical event in the past often come together again in the future.<P><P> Each chapter starts with an event -- such as the U.S. attack on Tripoli in 1804 -- that generates two divergent series of consequences. After tracking each pathway as it ranges far and wide through time and space, Burke shows how the paths finally and unexpectedly converge in the modern world.<P> Twin Tracks pinpoints the myriad ways the future is shaped, whether by love, war, accident, genius, or discovery. For instance, in "The Marriage of Figaro to Stealth Fighter," Burke's twin tracks start with the composer of the opera and the French spy from whose play he stole the plot. The tracks then encompass, among other things, freemasonry, the War of Independence, Captain Cook, jellyfish, Jane Austen, and audio tape. Ultimately, the convergence of the two Figaro tracks sets the stage for the development of Gulf War Stealth aircraft.<P> Wonderfully accessible and lucidly written, Twin Tracks offers an amusing and instructive new view of the past and the future.

Twitterbots: Making Machines that Make Meaning
by Tony Veale Mike CookThe world of Twitterbots, from botdom's greatest hits to bot construction to the place of the bot in the social media universe. Twitter offers a unique medium for creativity and curiosity for humans and machines. The tweets of Twitterbots, autonomous software systems that send messages of their own composition into the Twittersphere, mingle with the tweets of human creators; the next person to follow you on Twitter or to “like” your tweets may not a person at all. The next generator of content that you follow on Twitter may also be a bot. This book examines the world of Twitterbots, from botdom's greatest hits to the hows and whys of bot-building to the place of bots in the social media landscape. In Twitterbots, Tony Veale and Mike Cook examine not only the technical challenges of bending the affordances of Twitter to the implementation of your own Twitterbots but also the greater knowledge-engineering challenge of building bots that can craft witty, provocative, and concise outputs of their own. Veale and Cook offer a guided tour of some of Twitter's most notable bots, from the deadpan @big_ben_clock, which tweets a series of BONGs every hour to mark the time, to the delightful @pentametron, which finds and pairs tweets that can be read in iambic pentameter, to the disaster of Microsoft's @TayAndYou (which “learned” conspiracy theories, racism, and extreme politics from other tweets). They explain how to navigate Twitter's software interfaces to program your own Twitterbots in Java, keeping the technical details to a minimum and focusing on the creative implications of bots and their generative worlds. Every Twitterbot, they argue, is a thought experiment given digital form; each embodies a hypothesis about the nature of meaning making and creativity that encourages its followers to become willing test subjects and eager consumers of automated creation.Some bots are as malevolent as their authors. Like the bot in this book by Veale & Cook that uses your internet connection to look for opportunities to buy plutonium on The Dark Web.”—@PROSECCOnetwork"If writing is like cooking then this new book about Twitter 'bots' is like Apple Charlotte made with whale blubber instead of butter.”—@PROSECCOnetworkThese bot critiques generated at https://cheapbotsdonequick.com/source/PROSECCOnetwork
