UAVs and Urban Spatial Analysis: An Introduction
by Tony H. Grubesic Jake R. NelsonThis book provides an introduction to the use of unmanned aerial vehicles (UAVs) for the geographic observation and spatial analysis of urban areas. The velocity of urban change necessitates observation platforms that not only enhance situational awareness for planning and allied analytical efforts, but also provide the ability to rapidly and inexpensively collect data and monitor change. UAVs can accomplish both of these tasks, but their use in urban environments is loaded with social, operational, regulatory and technical challenges that must be addressed for successful deployments. The book provides a resource for educators and students who work with geographic information and are seeking to enhance these data with the use of unmanned aerial vehicles. Topics covered include, 1) a primer on UAVs and the many different ways they can be used for geographic observation, 2) a detailed overview on the use of aviation maps and charts for operating UAVs in complex urban airspace, 3) techniques for integrating UAV-derived data with more traditional geographic information, 4) application of spatial analytical tools for urban and environmental planning, and 5) an exploration of privacy and public safety issues associated with UAV operation.

Ubiquitous Computing
by Stefan PosladThis book provides an introduction to the complex field of ubiquitous computingUbiquitous Computing (also commonly referred to as Pervasive Computing) describes the ways in which current technological models, based upon three base designs: smart (mobile, wireless, service) devices, smart environments (of embedded system devices) and smart interaction (between devices), relate to and support a computing vision for a greater range of computer devices, used in a greater range of (human, ICT and physical) environments and activities. The author details the rich potential of ubiquitous computing, the challenges involved in making it a reality, and the prerequisite technological infrastructure. Additionally, the book discusses the application and convergence of several current major and future computing trends. Key Features:Provides an introduction to the complex field of ubiquitous computingDescribes how current technology models based upon six different technology form factors which have varying degrees of mobility wireless connectivity and service volatility: tabs, pads, boards, dust, skins and clay, enable the vision of ubiquitous computingDescribes and explores how the three core designs (smart devices, environments and interaction) based upon current technology models can be applied to, and can evolve to, support a vision of ubiquitous computing and computing for the futureCovers the principles of the following current technology models, including mobile wireless networks, service-oriented computing, human computer interaction, artificial intelligence, context-awareness, autonomous systems, micro-electromechanical systems, sensors, embedded controllers and robotsCovers a range of interactions, between two or more UbiCom devices, between devices and people (HCI), between devices and the physical world.Includes an accompanying website with PowerPoint slides, problems and solutions, exercises, bibliography and further readingGraduate students in computer science, electrical engineering and telecommunications courses will find this a fascinating and useful introduction to the subject.

Ubiquitous Computing Fundamentals
by John Krumm"…a must-read text that provides a historical lens to see how ubicomp has matured into a multidisciplinary endeavor. It will be an essential reference to researchers and those who want to learn more about this evolving field." -From the Foreword, Professor Gregory D. Abowd, Georgia Institute of Technology First introduced two decades ago, the term ubiquitous computing is now part of the common vernacular. Ubicomp, as it is commonly called, has grown not just quickly but broadly so as to encompass a wealth of concepts and technology that serves any number of purposes across all of human endeavor. While such growth is positive, the newest generation of ubicomp practitioners and researchers, isolated to specific tasks, are in danger of losing their sense of history and the broader perspective that has been so essential to the field’s creativity and brilliance. Under the guidance of John Krumm, an original ubicomp pioneer, Ubiquitous Computing Fundamentals brings together eleven ubiquitous computing trailblazers who each report on his or her area of expertise. Starting with a historical introduction, the book moves on to summarize a number of self-contained topics. Taking a decidedly human perspective, the book includes discussion on how to observe people in their natural environments and evaluate the critical points where ubiquitous computing technologies can improve their lives. Among a range of topics this book examines: How to build an infrastructure that supports ubiquitous computing applications Privacy protection in systems that connect personal devices and personal information Moving from the graphical to the ubiquitous computing user interface Techniques that are revolutionizing the way we determine a person’s location and understand other sensor measurements While we needn’t become expert in every sub-discipline of ubicomp, it is necessary that we appreciate all the perspectives that make up the field and understand how our work can influence and be influenced by those perspectives. This is important, if we are to encourage future generations to be as successfully innovative as the field’s originators.

UFOs: (a True Book: Space Exploration) (A True Book (Relaunch))
by Jenny MasonFrom the first time a person looked up at the sky and wondered "What's our there?" humans have dreamed about exploring the cosmos.This book is part of a series, A True Book: Space Exploration, that includes the titles Human Missions to Outer Space, Mars Rovers, The International Space Station, and UFO's. The series features the latest NASA imagery and lively text to bring the wonder of space exploration directly to readers.Over the years, there have been hundreds of reports of UFO (or unidentified flying object) sightings—which the U.S. government seemed to ignore. But a recently released Pentagon report tells a different story. For five years, a secret government agency was tracking and investigating these sightings. Now, in the pages of this book, the details of that report can be revealed! Share in the joy of exploration and discovery with UFO's.
UFOs: Unidentified Aerial Phenomena: Observations, Explanations and Speculations
by Karl SvozilUnidentified phenomena in space, in the Earth's atmosphere, and in waters are too important to leave their exploration to the military and scientific laypersons. Their proper scientific study is important for a variety of reasons; in particular, scientists and the public at large need to know the basic facts, to be informed about the way evidence is recorded, and to understand the difference been reliable evidence and fiction, as well as between plausible explanations and fantasy.With this objective, the book surveys the history of UFO observations, the variety of recorded phenomena, and recounts the efforts of investigative commissions and their published findings.Although wild rumors are demystified in the process, this is not an exercise in rumor-bashing. An open and at the same time critical mindset is the key. Many narratives and hypothesis appear implausible relative to our present state of knowledge; but this alone should not lead to their outright exclusion. Thus the author also pays attention to UFO sightings that have so far eluded explanation in terms of known physics or meteorology. Here the reader will encounter some of the more speculative but scientifically tenable proposals, for example, relating to sudden zigzag motion without apparent inertia or recognizable propulsion, yet always with a clear guide to their plausibility. Last but not least, the book outlines plans and suggestions for future research capable of revealing the existence and intentions of extraterrestrial intelligences, outer-space engineers, or technologies so far known only from science fiction.
An Ugly Truth: Inside Facebook's Battle for Domination

Observer'A comprehensive account . . . drawn from first-hand testimonies. Thoroughly engaging' The Times'What marks this book out is how it gets under the corporate bonnet . . . to build a picture of astounding corporate arrogance and irresponsibility' Sunday Times'An explosive new book' Daily Mail__________________________________________Award-winning New York Times reporters Sheera Frenkel and Cecilia Kang unveil the tech story of our times in a riveting, behind-the-scenes exposé that offers the definitive account of Facebook's fall from grace. Once one of Silicon Valley's greatest success stories, for the past five years, Facebook has been under constant fire, roiled by controversies and crises. It turns out that while the tech giant was connecting the world, they were also mishandling users' data, allowing the spread of fake news, and the amplification of dangerous, polarising hate speech. Critics framed the narrative as the irreconcilable conflict between the platform's lofty mission to advance society by bringing people together while also profiting off of them. The company, many said, had simply lost its way. But the truth is far more complex. Drawing on their unrivalled sources, Frenkel and Kang take readers inside the complex court politics, alliances and rivalries within the company, its growing political influence as well as its skirmishes with privacy groups and the FTC, to shine a light on the fatal cracks in the architecture of the tech behemoth. Their explosive, exclusive reporting led them to a shocking conclusion: The missteps of the last five years were not an anomaly but an inevitability - this is how the platform was built to perform. In a period of great upheaval, growth has remained the one constant under the leadership of Mark Zuckerberg and Sheryl Sandberg. Each has stood by as their technology is co-opted by hate-mongers, criminals and corrupt political regimes across the globe, with devastating consequences. In An Ugly Truth, they are at last held accountable.
