Opportunities to Use Remote Sensing in Understanding Permafrost and Related Ecological Characteristics: Report of a Workshop
by Committee on Opportunities to Use Remote Sensing in Understanding Permafrost Ecosystems: A WorkshopPermafrost is a thermal condition -- its formation, persistence and disappearance are highly dependent on climate. General circulation models predict that, for a doubling of atmospheric concentrations of carbon dioxide, mean annual air temperatures may rise up to several degrees over much of the Arctic. In the discontinuous permafrost region, where ground temperatures are within 1-2 degrees of thawing, permafrost will likely ultimately disappear as a result of ground thermal changes associated with global climate warming. Where ground ice contents are high, permafrost degradation will have associated physical impacts. Permafrost thaw stands to have wide-ranging impacts, such as the draining and drying of the tundra, erosion of riverbanks and coastline, and destabilization of infrastructure (roads, airports, buildings, etc. ), and including potential implications for ecosystems and the carbon cycle in the high latitudes. "Opportunities to Use Remote Sensing in Understanding Permafrost and Related Ecological Characteristics" is the summary of a workshop convened by the National Research Council to explore opportunities for using remote sensing to advance our understanding of permafrost status and trends and the impacts of permafrost change, especially on ecosystems and the carbon cycle in the high latitudes. The workshop brought together experts from the remote sensing community with permafrost and ecosystem scientists. The workshop discussions articulated gaps in current understanding and potential opportunities to harness remote sensing techniques to better understand permafrost, permafrost change, and implications for ecosystems in permafrost areas. This report addresses questions such as how remote sensing might be used in innovative ways, how it might enhance our ability to document long-term trends, and whether it is possible to integrate remote sensing products with the ground-based observations and assimilate them into advanced Arctic system models. Additionally, the report considers the expectations of the quality and spatial and temporal resolution possible through such approaches, and the prototype sensors that are available that could be used for detailed ground calibration of permafrost/high latitude carbon cycle studies.
Opportunity, Montana: Big Copper, Bad Water, and the Burial of an American Landscape
by Brad TyerA memoir-meets-exposé that examines our fraught relationship with the West and our attempts to clean up a toxic environmental legacy In 2002, Texas journalist Brad Tyer strapped a canoe on his truck and moved to Montana, a state that has long exerted a mythic pull on America's imagination as an unspoiled landscape. The son of an engineer who reclaimed wastewater, Tyer was looking for a pristine river to call his own. What he found instead was a century's worth of industrial poison clotting the Clark Fork River, a decades-long engineering project to clean it up, and a forgotten town named Opportunity. At the turn of the nineteenth century, Montana exploited the richest copper deposits in the world, fueling the electric growth of twentieth-century America and building some of the nation's most outlandish fortunes. The toxic by-product of those fortunes--what didn't spill into the river--was dumped in Opportunity. In the twenty-first century, Montana's draw is no longer metal but landscape: the blue-ribbon trout streams and unspoiled wilderness of the nation's "last best place." To match reality to the myth, affluent exurbanites and well-meaning environmentalists are trying to restore the Clark Fork River to its "natural state." In the process, millions of tons of toxic soils are being removed and dumped--once again--in Opportunity. As Tyer investigates Opportunity's history, he wrestles with questions of environmental justice and the ethics of burdening one community with an entire region's waste. Stalled at the intersection of a fading extractive economy and a fledgling restoration boom, Opportunity's story is a secret history of the American Dream and a key to understanding the country's--and increasingly the globe's--demand for modern convenience. As Tyer explores the degradations of the landscape, he also probes the parallel emotional geography of familial estrangement. Part personal history and part reportorial narrative, Opportunity, Montana is a story of progress and its price: of copper and water, of father and son, and of our attempts to redeem the mistakes of the past. From the Hardcover edition.
Optical and SAR Remote Sensing of Urban Areas: A Practical Guide (Springer Geography)
by Courage KamusokoThis book introduces remotely sensed image processing for urban areas using optical and synthetic aperture radar (SAR) data and assists students, researchers, and remote sensing practitioners who are interested in land cover mapping using such data. There are many introductory and advanced books on optical and SAR remote sensing image processing, but most of them do not serve as good practical guides. However, this book is designed as a practical guide and a hands-on workbook, where users can explore data and methods to improve their land cover mapping skills for urban areas. Although there are many freely available earth observation data, the focus is on land cover mapping using Sentinel-1 C-band SAR and Sentinel-2 data. All remotely sensed image processing and classification procedures are based on open-source software applications such QGIS and R as well as cloud-based platforms such as Google Earth Engine (GEE). The book is organized into six chapters. Chapter 1 introduces geospatial machine learning, and Chapter 2 covers exploratory image analysis and transformation. Chapters 3 and 4 focus on mapping urban land cover using multi-seasonal Sentinel-2 imagery and multi-seasonal Sentinel-1 imagery, respectively. Chapter 5 discusses mapping urban land cover using multi-seasonal Sentinel-1 and Sentinel-2 imagery as well as other derived data such as spectral and texture indices. Chapter 6 concludes the book with land cover classification accuracy assessment.
Optical Binding Phenomena: Observations and Mechanisms
by Jonathan M. TaylorThis thesis addresses optical binding - a new area of interest within the field of optical micromanipulation. It presents, for the first time, a rigorous numerical simulation of some of the key results, along with new experimental findings and also physical interpretations of the results. In an optical trap particles are attracted close to areas of high optical intensities and intensity gradients. So, for example, if two lasers are pointed towards each other (a counter propagating trap) then a single particle is trapped in the centre of the two beams - the system is analogous to a particle being held by two springs in a potential well. If one increases the number of particles in the trap then naively one would expect all the particles to collect in the centre of the well. However, the effect of optical binding means that the presence of one particle affects the distribution of light experienced by another particle, resulting in extremely complex interactions that can lead to unusual 1D and 2D structures to form within the trap. Optical binding is not only of theoretical interest but also has applications in micromanipulation and assembly.

Optical Hall Effect in the Sharp Focus of Laser Light
by Victor V. Kotlyar Alexey A. Kovalev Anton G. NalimovThis book explores the optical Hall effect in the sharp focus of laser light. It builds upon the established theory of Richards-Wolf (1959), providing numerous real-world examples that illustrate both spin and orbital Hall effects near the focal point. Within the focal zone, distinct regions of left and right circular polarization emerge, showcasing the orbital Hall effect. This effect becomes apparent when localized areas within the focal plane experience transverse energy flow, rotating either clockwise or counterclockwise. The spin Hall effect, a fundamental occurrence, is demonstrated when a linearly polarized Gaussian beam is concentrated. Furthermore, the book reveals spin and orbital Hall effects in light fields with nonuniform linear polarization, where the polarization direction varies within the beam cross section. While the optical or photonic Hall effect has been recognized since 2004, a comprehensive monograph detailing its focal dynamics has been lacking until now. Drawing from the cohesive theoretical framework of the Richards-Wolf theory, this book offers specific examples and results from computer modeling. It equips readers with analytical relations for calculating energy and spin fluxes near a sharp focus across various initial light vector fields. Designed for a diverse audience, including scientists, engineers, and students in optics and photonics, this book serves as a valuable resource. It caters to undergraduate and graduate students in applied mathematics, physics, informatics, and optics, and can also benefit researchers and professionals in the field. Moreover, the book holds potential as a foundational text for advanced graduate courses

Optical Polymer Waveguides: From the Design to the Final 3D-Opto Mechatronic Integrated Device
by Jörg Franke Ludger Overmeyer Norbert Lindlein Karlheinz Bock Stefan Kaierle Oliver Suttmann Klaus-Jürgen WolterLight signals in optical waveguides can be used to transmit very large amounts of data quickly and largely without interference. In the industrial and infrastructural sectors, e.g. in the automotive and aerospace industries, the demand to further exploit this potential is therefore increasing. Which technologies can be used to effectively integrate systems that transmit data by means of light into existing components? This is a central question for current research. So far, there have been some technical limitations in this regard. For example, it is difficult to couple the signal of an optical waveguide to other optical waveguides without interruption. There is also a lack of suitable fabrication technologies for three-dimensional waveguides, as well as design and simulation environments for 3D opto-MID. This book addresses these and other challenges.
Optically Trapped Microspheres as Sensors of Mass and Sound: Brownian Motion as Both Signal and Noise (Springer Theses)
by Logan Edward HillberryThis thesis makes significant advances in the use of microspheres in optical traps as highly precise sensing platforms. While optically trapped microspheres have recently proven their dominance in aqueous and vacuum environments, achieving state-of-the-art measurements of miniscule forces and torques, their sensitivity to perturbations in air has remained relatively unexplored. This thesis shows that, by uniquely operating in air and measuring its thermally-fluctuating instantaneous velocity, an optically trapped microsphere is an ultra-sensitive probe of both mass and sound. The mass of the microsphere is determined with similar accuracy to competitive methods but in a fraction of the measurement time and all while maintaining thermal equilibrium, unlike alternative methods. As an acoustic transducer, the air-based microsphere is uniquely sensitive to the velocity of sound, as opposed to the pressure measured by a traditional microphone. By comparison to state-of-the-art commercially-available velocity and pressure sensors, including the world’s smallest measurement microphone, the microsphere sensing modality is shown to be both accurate and to have superior sensitivity at high frequencies. Applications for such high-frequency acoustic sensing include dosage monitoring in proton therapy for cancer and event discrimination in bubble chamber searches for dark matter. In addition to reporting these scientific results, the thesis is pedagogically organized to present the relevant history, theory, and technology in a straightforward way.
Optimal Control of Age-structured Populations in Economy, Demography, and the Environment (Routledge Explorations In Environmental Economics Ser. #29)
by Natali Hritonenko Yuri Yatsenko Raouf BoucekkineThis book covers a wide range of topics within mathematical modelling and the optimization of economic, demographic, technological and environmental phenomena. Each chapter is written by experts in their field and represents new advances in modelling theory and practice. These essays are exemplary of the fruitful interaction between theory and practice when exploring global and local changes. The unifying theme of the book is the use of mathematical models and optimization methods to describe age-structured populations in economy, demography, technological change, and the environment. Emphasis is placed on deterministic dynamic models that take age or size structures, delay effects, and non-standard decision variables into account. In addition, the contributions deal with the age structure of assets, resources, and populations under study. Interdisciplinary modelling has enormous potential for discovering new insights in global and regional development. Optimal Control of Age-structured Populations in Economy, Demography, and the Environment is a rich and excellent source of information on state-of-the-art modelling expertise and references. The book provides the necessary mathematical background for readers from different areas, such as applied sciences, management sciences and operations research, which helps guide the development of practical models. As well as this the book also surveys the current practice in applied modelling and looks at new research areas for a general mathematical audience. This book will be of interest primarily to researchers, postgraduate students, as well as a wider scientific community, including those focussing on the subjects of applied mathematics, environmental sciences, economics, demography, management, and operations research.
Optimal Economic Growth with Exhaustible Resources (Routledge Library Editions: Environmental and Natural Resource Economics)
by Prem C. GargOriginally published in 1979. For decades conservationists have argued that increasing population will eventually out-strip the limited natural resources of the earth. Economists have responded by saying that any resource scarcity will be forestalled by changes in tastes and technology, induced by the appropriate price signals. This study is an attempt to develop a theoretical framework for analysing some of the issues related to this debate. Using an optimal growth theory framework, the author analyses the problem of optimally allocating a finite stock of the resource over time. In the process the author points out the crucial parameters and value judgments relevant to the various issues. This title will be of interest to students of environmental economics.
Optimal Mobile Sensing and Actuation Policies in Cyber-physical Systems
by Yangquan Chen Christophe TricaudA successful cyber-physical system, a complex interweaving of hardware and software with some part of the physical environment, depends on proper identification of the, often pre-existing, physical element. A bespoke "cyber" part of the system may then be designed from scratch. Optimal Mobile Sensing and Actuation Strategies in Cyber-physical Systems focuses on distributed-parameter systems the dynamics of which can be modelled with partial differential equations. These are very challenging to observe, their states and inputs being distributed throughout a spatial domain. Consequently, systematic approaches to the optimization of sensor location have to be devised for parameter estimation. The text begins by reviewing the field of cyber-physical systems and introducing background notions of distributed parameter systems and optimal observation theory. New research problems are then defined within this framework. Two important problems considered are optimal mobile sensor trajectory planning and the accuracy effects and allocation of remote sensors. These are followed up with a solution to the problem of optimal robust estimation. Actuation policies are then introduced into the framework with the purpose of improving estimation and optimizing the trajectories of both sensors and actuators simultaneously. The large number of illustrations within the text will assist the reader to visualize the application of the methods proposed. A group of similar examples are used throughout the book to help the reader assimilate the material more easily. The monograph concentrates on the use of methods for which a cyber-physical-systems infrastructure is required. The methods are computationally heavy and require mobile sensors and actuators with communications abilities. Application examples cover fields from environmental science to national security so that readers are encouraged to link the ideas of cyber-physical systems with their own research.
Optimal Reliability-Based Design of Structures Against Several Natural Hazards
by Alfredo H-S Ang David de Escobedo Wenliang FanInterest in the topic of structural reliability and optimal design has been rapidly growing in recent years. Besides, the field of numerical methods and artificial intelligence is experiencing a surge of new methods and the refinement of existing ones to expand opportunities to apply robust formulations to complex engineering problems. Today, more than ever, the field is receiving fresh ideas on how to face the challenges of finding a balance between cost and benefits that may lead towards the optimal design of systems. Recently, the probability density evolution method (PDEM) was proposed by Prof. Jie Li as an alternative way to obtain the stochastic and dynamic solution of the safety level of engineering systems under any kind of hazard. This work deals with the application of this powerful method to derive optimal design recommendations for large engineering systems under natural hazards. The three case studies illustrate to engineers and academic specialists how to strike a cost-effective balance in designing such systems.
Optimal Surface Fitting of Point Clouds Using Local Refinement: Application to GIS Data (SpringerBriefs in Earth System Sciences)
by Gaël Kermarrec Vibeke Skytt Tor DokkenThis open access book provides insights into the novel Locally Refined B-spline (LR B-spline) surface format, which is suited for representing terrain and seabed data in a compact way. It provides an alternative to the well know raster and triangulated surface representations. An LR B-spline surface has an overall smooth behavior and allows the modeling of local details with only a limited growth in data volume. In regions where many data points belong to the same smooth area, LR B-splines allow a very lean representation of the shape by locally adapting the resolution of the spline space to the size and local shape variations of the region. The iterative method can be modified to improve the accuracy in particular domains of a point cloud. The use of statistical information criterion can help determining the optimal threshold, the number of iterations to perform as well as some parameters of the underlying mathematical functions (degree of the splines, parameter representation). The resulting surfaces are well suited for analysis and computing secondary information such as contour curves and minimum and maximum points. Also deformation analysis are potential applications of fitting point clouds with LR B-splines.
Optimal Transport for Applied Mathematicians
by Filippo SantambrogioThis monograph presents a rigorous mathematical introduction to optimal transport as a variational problem, its use in modeling various phenomena, and its connections with partial differential equations. Its main goal is to provide the reader with the techniques necessary to understand the current research in optimal transport and the tools which are most useful for its applications. Full proofs are used to illustrate mathematical concepts and each chapter includes a section that discusses applications of optimal transport to various areas, such as economics, finance, potential games, image processing and fluid dynamics. Several topics are covered that have never been previously in books on this subject, such as the Knothe transport, the properties of functionals on measures, the Dacorogna-Moser flow, the formulation through minimal flows with prescribed divergence formulation, the case of the supremal cost, and the most classical numerical methods. Graduate students and researchers in both pure and applied mathematics interested in the problems and applications of optimal transport will find this to be an invaluable resource.
Optimised Projections for the Ab Initio Simulation of Large and Strongly Correlated Systems
by David D. O'ReganDensity functional theory (DFT) has become the standard workhorse for quantum mechanical simulations as it offers a good compromise between accuracy and computational cost. However, there are many important systems for which DFT performs very poorly, most notably strongly-correlated materials, resulting in a significant recent growth in interest in 'beyond DFT' methods. The widely used DFT+U technique, in particular, involves the addition of explicit Coulomb repulsion terms to reproduce the physics of spatially-localised electronic subspaces. The magnitude of these corrective terms, measured by the famous Hubbard U parameter, has received much attention but less so for the projections used to delineate these subspaces. The dependence on the choice of these projections is studied in detail here and a method to overcome this ambiguity in DFT+U, by self-consistently determining the projections, is introduced. The author shows how nonorthogonal representations for electronic states may be used to construct these projections and, furthermore, how DFT+U may be implemented with a linearly increasing cost with respect to system size. The use of nonorthogonal functions in the context of electronic structure calculations is extensively discussed and clarified, with new interpretations and results, and, on this topic, this work may serve as a reference for future workers in the field.

Options to Ensure the Climate Record from the NPOESS and GOES-R Spacecraft: A Workshop Report
by National Research Council of the National AcademiesIn 2000, the nation’s next-generation National Polar-orbiting Operational Environmental Satellite System (NPOESS) program anticipated purchasing six satellites for $6.5 billion, with a first launch in 2008. By November 2005, however, it became apparent that NPOESS would overrun its cost estimates by at least 25 percent. In June 2006, the planned acquisition of six spacecraft was reduced to four, the launch of the first spacecraft was delayed until 2013, and several sensors were canceled or descoped in capability. To examine the impacts of these changes, particularly those associated with climate research, and ways to mitigate those impacts, NASA and NOAA asked the NRC to add this task to its ongoing "decadal survey," Earth Science and Applications from Space. The sponsors and the NRC agreed to address this task separately and to base its analysis on a major workshop. This book presents summaries of discussions at the workshop, which included sessions on the measurements and sensors originally planned for NPOESS and GOES-R; generation of climate data records; mitigation options, including the role of international partners; and cross-cutting issues.
The Oracle of Oil: A Maverick Geologist's Quest for a Sustainable Future
by Mason InmanThe first comprehensive biography of Marion King Hubbert, the "father of peak oil." In 1956, geologist and Shell Oil researcher Marion King Hubbert delivered a speech that has shaped world energy debates ever since. Addressing the American Petroleum Institute, Hubbert dropped a bombshell on his audience: U.S. oil production would peak by 1970 and decline steadily thereafter. World production would follow the same fate, reaching its peak soon after the turn of the millennium. In battles stretching over decades, Hubbert defended his forecasts against opponents from both the oil industry and government. Hubbert was proved largely correct during the energy crises of the 1970s and hailed as a "prophet" and an "oracle." Even amid our twenty-first-century fracking boom, Hubbert's underlying logic holds true--while remaining a source of debate and controversy. A rich biography of the man behind peak oil, The Oracle of Oil follows Hubbert from his early days as a University of Chicago undergraduate to his first, ill-fated forays into politics in the midcentury Technocracy movement, and charts his rise as a top geologist in the oil industry and energy expert within the U.S. government. In a deeply researched narrative that mines Hubbert's papers and correspondence for the first time, award-winning journalist Mason Inman rescues the story of a man who shocked the scientific community with his eccentric brilliance. The Oracle of Oil also skillfully situates Hubbert in his era: a time of great intellectual ferment and discovery, tinged by dark undercurrents of intellectual witch hunts. Hubbert emerges as an unapologetic iconoclast who championed sustainability through his lifelong quest to wean the United States--and the wider world--off fossil fuels, as well as by questioning the pursuit of never-ending growth. In its portrait of a man whose prescient ideas still resonate today, The Oracle of Oil looks to the past to find a guiding philosophy for our future.
The Orang Suku Laut of Riau, Indonesia: The inalienable gift of territory (The Modern Anthropology of Southeast Asia)
by Cynthia ChouLand reform has been an indisputable part of Indonesian revolution. The consequent execution of development programmes for nation-building have provoked intense hostility over territorial rights. Global market forces in Indonesia have seen increasing flows of transnational investments, technology and resources that have resulted in great demand on sea and land spaces. In this momentum of change, several aspects of rural culture including indigenous populations, like the Orang Suku Laut (people of the sea) of Riau have been deemed by the state architects of development programmes to hinder progress. For generations, the sea and coastal places have been the life and living spaces of the Orang Suku Laut and they claim ownership to these territories based upon customary laws. The developmental pressure thus generated has led to intense struggles over territorial rights. It has also raised issues concerning the social assimilation of indigenous peoples as citizens, religious conversion and cultural identity. Cynthia Chou discusses how Indonesian nation-building development programmes have generated intense struggles over issues pertaining to territorial rights, social assimilation of indigenous peoples as citizens, religious conversion and cultural identity This book is a stimulating read for those interested in Social and Cultural Anthropology, Development Studies and Southeast Asian Studies.
Oranges
by John McpheeA classic of reportage, Oranges was first conceived as a short magazine article about oranges and orange juice, but the author kept encountering so much irresistible information that he eventually found that he had in fact written a book. It contains sketches of orange growers, orange botanists, orange pickers, orange packers, early settlers on Florida’s Indian River, the first orange barons, modern concentrate makers, and a fascinating profile of Ben Hill Griffin of Frostproof, Florida who may be the last of the individual orange barons. McPhee’s astonishing book has an almost narrative progression, is immensely readable, and is frequently amusing. Louis XIV hung tapestries of oranges in the halls of Versailles, because oranges and orange trees were the symbols of his nature and his reign. This book, in a sense, is a tapestry of oranges, too--with elements in it that range from the great orangeries of European monarchs to a custom of people in the modern Caribbean who split oranges and clean floors with them, one half in each hand.
The Orbital Perspective
by Muhammad Yunus Astronaut Ron GaranFor astronaut Ron Garan, living on the International Space Station was a powerful, transformative experience--one that he believes holds the key to solving our problems here on Earth. On space walks and through windows, Garan was struck by the stunning beauty of the Earth from space but sobered by knowing how much needed to be done to help this troubled planet. And yet on the International Space Station, Garan, a former fighter pilot, was working work side by side with Russians, who only a few years before were "the enemy." If fifteen nationalities could collaborate on one of the most ambitious, technologically complicated undertakings in history, surely we can apply that kind of cooperation and innovation toward creating a better world. That spirit is what Garan calls the "orbital perspective."Garan vividly conveys what it was like learning to work with a diverse group of people in an environment only a handful of human beings have ever known. But more importantly, he describes how he and others are working to apply the orbital perspective here at home, embracing new partnerships and processes to promote peace and combat hunger, thirst, poverty, and environmental destruction. This book is a call to action for each of us to care for the most important space station of all: planet Earth. You don't need to be an astronaut to have the orbital perspective. Garan's message of elevated empathy is an inspiration to all who seek a better world.
Orbital Relative Motion and Terminal Rendezvous: Analytic and Numerical Methods for Spaceflight Guidance Applications (Space Technology Library #39)
by Jean Albert KéchichianThis book provides a comprehensive analysis of time-fixed terminal rendezvous around the Earth using chemical propulsion.The book has two main objectives. The first is to derive the mathematics of relative motion in near-circular orbit when subjected to perturbations emanating from the oblateness of the Earth, third-body gravity, and atmospheric drag. The mathematics are suitable for quick trajectory prediction and the creation of computer codes and efficient software to solve impulsive maneuvers and fly rendezvous missions.The second objective of this book is to show how the relative motion theory is applied to the exact precision-integrated, long-duration, time-fixed terminal rendezvous problem around the oblate Earth for the general elliptic orbit case.The contents are both theoretical and applied, with long-lasting value for aerospace engineers, trajectory designers, professors of orbital mechanics, and students at the graduate level and above.
