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.

The Unfinished Game: Pascal, Fermat, and the Seventeenth-Century Letter that Made the World Modern
by Keith DevlinIn the early seventeenth century, the outcome of something as simple as a dice roll was consigned to the realm of unknowable chance. Mathematicians largely agreed that it was impossible to predict the probability of an occurrence. Then, in 1654, Blaise Pascal wrote to Pierre de Fermat explaining that he had discovered how to calculate risk. The two collaborated to develop what is now known as probability theory?a concept that allows us to think rationally about decisions and events. In "The Unfinished Game," Keith Devlin masterfully chronicles Pascal and FermatOCOs mathematical breakthrough, connecting a centuries-old discovery with its remarkable impact on the modern world.

The Unforgotten Sisters
by Gabriella BernardiTakinginspiration from Siv Cedering's poem in the form of a fictional letter fromCaroline Herschel that refers to "my long, lost sisters, forgotten in the booksthat record our science", this book tells the lives of twenty-five femalescientists, with specific attention to astronomers and mathematicians. Each ofthe presented biographies is organized as a kind of "personal file"which sets the biographee's life in its historical context, documents her mainworks, highlights some curious facts, and records citations about her. Theselected figures are among the most representative of this neglected world,including such luminaries as Hypatia of Alexandra, Hildegard of Bingen,Elisabetha Hevelius, and Maria Gaetana Agnesi. They span a period of about 4000years, from En HeduAnna, the Akkadian princess, who was one of the firstrecognized female astronomers, to the dawn of the era of modern astronomy withCaroline Herschel and Mary Somerville. The book will be of interest to allwho wish to learn more about the women from antiquity to the nineteenth centurywho played such key roles in the history of astronomy and science despiteliving and working in largely male-dominated worlds.
The Unhappening of Genesis Lee
by Shallee McarthurWhat would it feel like to never forget? Or to have a memory stolen?Seventeen-year-old Genesis Lee has never forgotten anything. As one of the Mementi-a small group of genetically enhanced humans-Gena remembers everything with the help of her Link bracelets, which preserve them perfectly. But Links can be stolen, and six people have already lost their lives to a memory thief, including Gena's best friend.Anyone could be next. That's why Gena is less than pleased to meet a strange but charming boy named Kalan who claims not only that they have met before, but also that Gena knows who the thief is.The problem is that Gena doesn't remember Kalan, she doesn't remember seeing the thief, and she doesn't know why she's forgetting things-or how much else she might forget. As growing tensions between Mementi and ordinary humans drive the city of Havendale into chaos, Gena and Kalan team up to search for the thief. And as Gena loses more memories, they realize they have to solve the mystery fast...because Gena's life is unhappening around her.
Uniaxial Pressure Study of Charge Density Waves in a High-T꜀ Cuprate Superconductor (Springer Theses)
by Hun-ho KimThis book presents comprehensive studies of charge density waves (CDW) in a high-Tc cuprate superconductor using x-ray scattering techniques under uniaxial pressure. Specifically, the work addresses inelastic x-ray scattering studies under uniaxial pressure performed on the underdoped cuprate YBa2Cu3O6.67(p=0.12, Tc=65K) with incoming photon energy in the resonant (E=931.3 eV, Cu-L3 edge) and non-resonant conditions (E=17.794 keV). This is a completely new approach to the investigation of charge density waves. It revealed new features of charge density waves in cuprates, whose properties had previously been inaccessible..
Uniaxial Stress Technique and Investigations of Correlated Electron Systems (Springer Theses)
by Mark Edward BarberThis book reports on the development and application of a new uniaxial pressure apparatus that is currently generating considerable interest in the field of materials physics. The author provides practical guidelines for performing such experiments, backed up by finite element simulations. Subsequently, the book reports on two uses of the device. In the first, high pressures are used to tune to a Van Hove singularity in Sr2RuO4, while the effects on the unconventional superconductivity and the normal state properties are investigated. In the second experiment, precise and continuous strain control is used to probe symmetry breaking and novel phase formation in the vicinity of a quantum critical point in Sr3Ru2O7.
Unification of Fractional Calculi with Applications (Studies in Systems, Decision and Control #398)

AnastassiouThis book demonstrates the unifying methods of generalized versions of Hilfer, Prabhakar and Hilfer–Prabhakar fractional calculi, and we establish related unifying fractional integral inequalities of the following types: Iyengar, Landau, Polya, Ostrowski, Hilbert–Pachpatte, Hardy, Opial, Csiszar’s f-Divergence, self-adjoint operator and related to fuzziness. Our results are univariate and multivariate. This book’s results are expected to find applications in many areas of pure and applied mathematics, especially in fractional inequalities and fractional differential equations. Other interesting applications can be in applied sciences like geophysics, physics, chemistry, economics and engineering. This book is appropriate for researchers, graduate students, practitioners and seminars of the above disciplines, also to be in all science and engineering libraries.
A Unified Algebraic Approach To Control Design
by DimitriE. GrigoriadisThis text deals with the most fundamental deficiency of modern theory control: the lack of an easily applicable method for the design of low order controllers. It shows that solutions to many different problems in control all reduce to the same linear algebra problem. It employs matrix equalities and matrix inequalities in the solutions of fixed order control and also provides computational algorithms.
