Optimal Surface Fitting of Point Clouds Using Local Refinement: Application to GIS Data (SpringerBriefs in Earth System Sciences)
by Tor Dokken Gaël Kermarrec Vibeke SkyttThis 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.
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.
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.

Orca: Shared Waters, Shared Home
by Lynda MapesOrca whale J35, also known as "Tahlequah," gave birth in July of 2018 in the waters off British Columbia, but her calf died soon after, leading its mother to carry her for 17 days across 1000 miles before finally releasing the calf and rejoining her pod. This extraordinary and caring behavior sparked not only worldwide sympathy, but also a revival of our awareness of the critical need to preserve orcas, the chinook salmon they feed on, and their habitat that together make up the core of Pacific Northwest identity. In Orca: Shared Waters, Shared Home journalist Lynda V. Mapes explores the natural history of the orca and the unique challenges for survival of the Southern Resident group that frequents Puget Sound. These whales are among the most urban in the world, a focus of researchers, tourists, and politicians alike. Once referred to as "blackfish" and still known as "killer whales," orcas were for generations regarded as vermin to be avoided or exterminated, then later were captured live for aquariums all over the world. With greater exposure, scientists realized how intelligent the mammal is and are learning about their matriarchal family groups, vocalizations, behavior, and different subspecies. Today only 74 Southern Resident whales are left, and they are threatened by habitat degradation, lack of chinook salmon (their primary food source), relentless growth, and climate change. Can we reverse the trend? This special project, co-published with the Pulitzer Prize winning Seattle Times newspaper, features stunning imagery by Times photographer Steve Ringman, as well as from partner organizations including The Whale Museum, NOAA, and Center for Whale Research.
Orcas Everywhere: The History and Mystery of Killer Whales (Orca Wild #1)
by Mark Leiren-YoungOrcas are found in every ocean on the planet. But can they survive their relationship with humans? Orcas Everywhere looks at how humans around the world (Indigenous and non-Indigenous alike) related to orcas in the past, how we relate to them now and what we can do to keep cetacean communities alive and thriving. The book deals with science, philosophy, environmentalism and ethics in a kid-friendly and accessible way. Writer, filmmaker and orca activist Mark Leiren-Young takes us back to when killer whales were considered monsters and examines how humans went from using orcas for target practice to nearly loving them to death. If you know a young person who loves Free Willy or Finding Nemo, they will fall in love with these whales.

Order and Fluctuations in Collective Dynamics of Swimming Bacteria: Experimental Exploration of Active Matter Physics (Springer Theses)
by Daiki NishiguchiThis thesis focuses on experimental studies on collective motion using swimming bacteria as model active-matter systems. It offers comprehensive reviews of state-of-the-art theories and experiments on collective motion from the viewpoint of nonequilibrium statistical physics. The author presents his experimental studies on two major classes of collective motion that had been well studied theoretically. Firstly, swimming filamentous bacteria in a thin fluid layer are shown to exhibit true, long-range orientational order and anomalously strong giant density fluctuations, which are considered universal and landmark signatures of collective motion by many numerical and theoretical works but have never been observed in real systems. Secondly, chaotic bacterial turbulence in a three-dimensional dense suspension without any long-range order as described in the first half is demonstrated to be capable of achieving antiferromagnetic vortex order by imposing a small number of constraints with appropriate periodicity. The experimental results presented significantly advance our fundamental understanding of order and fluctuations in collective motion of motile elements and their future applications.
Ordinary Cities: Between Modernity and Development (Questioning Cities)
by Jennifer RobinsonWith the urbanization of the world's population proceeding apace and the equally rapid urbanization of poverty, urban theory has an urgent challenge to meet if it is to remain relevant to the majority of cities and their populations, many of which are outside the West. This groundbreaking book establishes a new framework for urban development. It makes the argument that all cities are best understood as ‘ordinary’, and crosses the longstanding divide in urban scholarship and urban policy between Western and other cities (especially those labelled ‘Third World’). It considers the two framing axes of urban modernity and development, and argues that if cities are to be imagined in equitable and creative ways, urban theory must overcome these axes with their Western bias and that resources must become at least as cosmopolitan as cities themselves. Tracking paths across previously separate literatures and debates, this innovative book - a postcolonial critique of urban studies - traces the outlines of a cosmopolitan approach to cities, drawing on evidence from Rio, Johannesburg, Lusaka and Kuala Lumpur. Key urban scholars and debates, from Simmel, Benjamin and the Chicago School to Global and World Cities theories are explored, together with anthropological and developmentalist accounts of poorer cities. Offering an alternative approach, Ordinary Cities skilfully brings together theories of urban development for students and researchers of urban studies, geography and development.
Ordinary Differential Equations with Applications (Texts in Applied Mathematics #34)
by Carmen ChiconeThis book, developed during 20 years of the author teaching differential equations courses at his home university, is designed to serve as a text for a graduate level course focused on the central theory of the subject with attention paid to applications and connections to other advanced topics in mathematics. Core theory includes local existence and uniqueness, the phase plane, Poincaré-Bendixson theory, Lyapunov and linearized stability, linear systems, Floquet theory, the Grobman–Hartman theorem, persistence of rest points and periodic orbits, the stable and center manifold theorems, and bifurcation theory. This edition includes expanded treatment of deterministic chaos, perturbation theory for periodic solutions, boundary value problems, optimization, and a wide range of their applications. In addition, it contains a formulation and new proof of a theorem on instability of rest points in the presence of an eigenvalue with positive real part, and new proofs of differential inequalities and Lyapunov’s center theorem. New sections present discussions of global bifurcation, the Crandall–Rabinowitz theorem, and Alekseev’s formula. Of particular note is a new chapter on basic control theory, a discussion of optimal control, and a proof of a useful special case of the maximum principle. A key feature of earlier editions, a wide selection of original exercises, is respected in this edition with the inclusion of a wealth of new exercises. Reviews of the first edition:“As an applied mathematics text on linear and nonlinear equations, the book by Chicone is written with stimulating enthusiasm. It will certainly appeal to many students and researchers.”—F. Verhulst, SIAM Review “The author writes lucidly and in an engaging conversational style.
