The Underwater Eye: How the Movie Camera Opened the Depths and Unleashed New Realms of Fantasy
by Margaret CohenA rich history of underwater filmmaking and how it has profoundly influenced the aesthetics of movies and public perception of the oceansIn The Underwater Eye, Margaret Cohen tells the fascinating story of how the development of modern diving equipment and movie camera technology has allowed documentary and narrative filmmakers to take human vision into the depths, creating new imagery of the seas and the underwater realm, and expanding the scope of popular imagination. Innovating on the most challenging film set on earth, filmmakers have tapped the emotional power of the underwater environment to forge new visions of horror, tragedy, adventure, beauty, and surrealism, entertaining the public and shaping its perception of ocean reality.Examining works by filmmakers ranging from J. E. Williamson, inventor of the first undersea film technology in 1914, to Wes Anderson, who filmed the underwater scenes of his 2004 The Life Aquatic with Steve Zissou entirely in a pool, The Underwater Eye traces how the radically alien qualities of underwater optics have shaped liquid fantasies for more than a century. Richly illustrated, the book explores documentaries by Jacques Cousteau, Louis Malle, and Hans Hass, art films by Man Ray and Jean Vigo, and popular movies and television shows such as 20,000 Leagues Under the Sea, Creature from the Black Lagoon, Sea Hunt, the Bond films, Jaws, The Abyss, and Titanic. In exploring the cultural impact of underwater filmmaking, the book also asks compelling questions about the role film plays in engaging the public with the remote ocean, a frontline of climate change.
Underwater Information Perception and Processing Via Underwater Sensor Networks
by Meiqin Liu Ronghao Zheng Senlin ZhangThis book highlights the latest advances and trends in information perception and processing of underwater sensor networks (USNs). Underwater sensor networks are networks of autonomous sensor nodes distributed over a given region of water to collaboratively perform a given task. Nearly 70% of the Earth's surface is covered by water, mainly oceans, and more than 80% of the ocean remains unexplored. The emergence of USNs is a new direction in ocean exploration and data collection. USNs offer many applications in both civilian and non-civilian fields. However, due to the characteristics of underwater environments, USNs face challenges such as limited bandwidth, high propagation delay, media access control, routing, resource utilization, power limitation, etc. Researchers have studied and provided many techniques over the past decades to address these issues. This book systematically summarizes the development and covers a wide range of applications of USNs, including mobile node localization, target detection, target recognition, target tracking, sensor scheduling, and environmental monitoring. It also focuses on the introduction of new technologies, including deep reinforcement learning, into underwater information perception and processing. This book is suitable for university lecturers, graduate students, and industry professionals working in the field of USNs.

Underwater Wireless Power Transfer: Smart Ocean Energy Converters (SpringerBriefs in Energy)
by Taofeek Orekan Peng ZhangThis book discusses, for the first time, wireless power transfer in the ocean environment. Topics covered include power electronic techniques, advanced control strategies, as well as classic and emerging applications such as smart ocean energy systems and wireless power transfer and charging of underwater autonomous vehicles. Emerging research topics are presented, along with methodologies, approaches, and industrial development of intelligent and energy-efficient techniques. Apart from the basic principles with an emphasis on inductive power transfer and mathematical analysis, the book discusses the emerging implementation for underwater wireless power transfer such as energy encryption, power and data transfer through common links, and secured data- and cyber-security. Specifically, the book comprehensively introduces significant discussions on UWPT coil theoretical and experimental analysis in seawater, optimal design, and intelligent controls. For example, since fast communication is not viable in an underwater environment, the proposed book discusses Maximum Power Efficiency Tracking (MPET) control, which achieves a maximum power efficiency (>85%) without communication or feedback from the transmitting side of the UWPT system. A k-nearest-neighbors-based machine learning approach is used to estimate the coupling coefficiency between the coils. This machine learning-based intelligent control method can offer important guidance for graduate students, academic researchers, and industrial engineers who want to understand the working principles and realize the developing trends in underwater wireless power transfer. Finally, the book includes details on the modeling and design of a smart ocean energy system--a new type of power harvesting system designed to convert ocean energy into electricity, which has the capability of making underwater wireless power connections with distributed marine devices.

Undiluted Hocus-Pocus: The Autobiography of Martin Gardner
by Martin GardnerThe autobiography of the beloved writer who inspired a generation to study math and scienceMartin Gardner wrote the Mathematical Games column for Scientific American for twenty-five years and published more than seventy books on topics as diverse as magic, religion, and Alice in Wonderland. Gardner's illuminating autobiography is a candid self-portrait by the man evolutionary theorist Stephen Jay Gould called our "single brightest beacon" for the defense of rationality and good science against mysticism and anti-intellectualism.Gardner takes readers from his childhood in Oklahoma to his varied and wide-ranging professional pursuits. He shares colorful anecdotes about the many fascinating people he met and mentored, and voices strong opinions on the subjects that matter to him most, from his love of mathematics to his uncompromising stance against pseudoscience. For Gardner, our mathematically structured universe is undiluted hocus-pocus—a marvelous enigma, in other words.Undiluted Hocus-Pocus offers a rare, intimate look at Gardner’s life and work, and the experiences that shaped both.
Undoing Ethics
by Natasha WhitemanOver the past decade, researchers from different academic disciplines have paid increasing attention to the productivity of online environments. The ethical underpinnings of research in such settings, however, remain contested and often controversial. As traditional debates have been reignited by the need to respond to the particular characteristics of technologically-mediated environments, researchers have entered anew key debates regarding the moral, legal and regulative aspects of research ethics. A growing trend in this work has been towards the promotion of localized and contextualized research ethics - the suggestion that the decisions we make should be informed by the nature of the environments we study and the habits/expectations of participants within them. Despite such moves, the relationship between the empirical, theoretical and methodological aspects of Internet research ethics remains underexplored. Drawing from ongoing sociological research into the practices of media cultures online, this book provides a timely and distinctive response to this need. This book explores the relationship between the production of ethical stances in two different contexts: the ethical manoeuvring of participants within online media-fan communities and the ethical decision-making of the author as Internet researcher, manoeuvring, as it were, in the academic community. In doing so, the book outlines a reflexive framework for exploring research ethics at different levels of analysis; the empirical settings of research; the theoretical perspectives which inform the researcher's objectification of the research settings; and the methodological issues and practical decisions that constitute the activity as research. The analysis of these different levels develops a way of thinking about ethical practice in terms of stabilizing and destabilizing moves within and between research and researched communities. The analysis emphasizes the continuities and discontinuities between both research practice and online media-fan activity, and social activity in on and offline environments.
Undoing Optimization: Civic Action in Smart Cities
by Alison B PowellA unique examination of the civic use, regulation, and politics of communication and data technologies City life has been reconfigured by our use—and our expectations—of communication, data, and sensing technologies. This book examines the civic use, regulation, and politics of these technologies, looking at how governments, planners, citizens, and activists expect them to enhance life in the city. Alison Powell argues that the de facto forms of citizenship that emerge in relation to these technologies represent sites of contention over how governance and civic power should operate. These become more significant in an increasingly urbanized and polarized world facing new struggles over local participation and engagement. The author moves past the usual discussion of top-down versus bottom-up civic action and instead explains how citizenship shifts in response to technological change and particularly in response to issues related to pervasive sensing, big data, and surveillance in &“smart cities.&”
Undoing Place?: A Geographical Reader (Arnold Readers In Geography Ser.)
by Linda McDowellDoes geography affect our sense of 'self'? How are social characteristics mapped out on the ground? And is there any 'authentic' sense of place now, or are we increasingly 'placeless'?Concentrating on the period between the end of the Second World War and the end of the century, this Reader argues that there is a reciprocal relationship between the constitution of places and people. What it means to be a man or a woman , to have a nationality and a sense of place, has been transformed and reinvented as our view of the world has changed. The present is perceived as a time of fear, a period in which all that is solid seems to melt into air, while the 1950s are a site of nostalgia, a period of clarity and certainty, a time when people know their place.Bringing together an interdisciplinary collection of articles for social and cultural geographers, this Reader critically examines the argument that the close associations of the 1950s between place (the home, the community and the nation state) and the social divisions (gender, class and nationality) are breaking down in the 1990s. Drawing out the oppositional movements in each decade, it seeks to show how the supposed stability of one and the mobility of the other are exaggerated.
Undoing the Damage: Silviculture for Ecologists and Environmental Scientists
by P A WojtkowskiAs a natural science, silviculture has a large say in how humans interact with the terrestrial world. Although the perspective taken here that the production of wood is narrow, the amount of land area consumed is extensive; the indirect consequences of wood production on natural processes are larger still. Through the amount of land engaged, the flora and fauna affected and the environmental consequences, good or bad; silviculture is a frequent constituent in applied ecology, environmental science, conservation ecology and other broad land-use disciplines. Silvicultural expertize is essential when trees and wood are an economic output; often best promoted when silviculture is allied with hydrology, ecology, soil science, wildlife management, etc. This book touches upon the following important areas of the subject in detail.

Unearthing the Nation: Modern Geology and Nationalism in Republican China
by Grace Yen ShenQuestions of national identity have long dominated ChinaOCOs political, social, and cultural horizons. So in the early 1900s, when diverse groups in China began to covet foreign science in the name of new technology and modernization, questions of nationhood came to the fore. In "Unearthing the Nation," Grace Yen Shen uses the development of modern geology to explore this complex relationship between science and nationalism in Republican China. aaaaaaaaaaaShen shows that Chinese geologistsOCoin battling growing Western and Japanese encroachment of Chinese sovereigntyOCofaced two ongoing challenges: how to develop objective, internationally recognized scientific authority without effacing native identity, and how to serve China when China was still searching for a stable national form. Shen argues that Chinese geologists overcame these obstacles by experimenting with different ways to associate the subjects of their scientific study, the land and its features, with the object of their political and cultural loyalties. This, in turn, led them to link national survival with the establishment of scientific authority in Chinese society. The first major history of modern Chinese geology, "Unearthing the Nation "introduces the key figures in the rise of the field, as well as several key organizations, such as the Geological Society of China, and explains how they helped bring Chinese geology onto the world stage.

The Unfamiliar Garden: The Comet Cycle Book 2 (The Comet Cycle #2)
by Benjamin PercyFrom award-winning author Benjamin Percy comes the second novel in his grippingly original sci-fi series, The Comet Cycle, in which a passing comet has caused irreversible change to the growth of fungi, spawning a dangerous, invasive species in the Pacific Northwest that threatens to control the lives of humans and animals alike.It began with a comet. They called it Cain, a wandering star that passed by Earth, illuminating the night with a swampy green light and twinning the sky by day with two suns. A year later, Earth spun through the debris field the comet left behind. Suddenly, hundreds of thousands of meteors plummeted into the atmosphere, destroying swaths of electrical grids, leaving shores of beaches filled with deceased sea life, and setting acres of land ablaze. It was then, they say, that the sky fell. It was then that Jack lost Mia.Five years after the disappearance of his daughter, Jack has fallen. Once an accomplished professor of botany, he's now a shell of a man who has all but withdrawn from life. Nora, his ex-wife, has thrown herself into her investigative work. Separately, they have each bandaged over the hole Mia left behind.Just as Jack is uncovering a new form of deadly parasitic fungus in his lab, Nora is assigned to investigate the cases of ritualistic murders dotting Seattle. The rituals consist of etchings - crosshatches are carved into bodies and eyes are scooped out of their sockets. The attackers appear to be possessed.It only takes a moment - for a sickness to infect, for a person to be killed, for a child to be lost. When Nora enlists Jack to identify the cause of this string of vicious deaths, Jack is quick to help. Together, they fight to keep their moments - the unexpected laughter, the extraordinary discoveries, the chance that Mia could come back home - but they find that what they're up against defies all logic, and what they have to do to save the world will change every life forever.
