Bayesian Optimization for Materials Science (SpringerBriefs in the Mathematics of Materials #3)
by Daniel PackwoodThis book provides a short and concise introduction to Bayesian optimization specifically for experimental and computational materials scientists. After explaining the basic idea behind Bayesian optimization and some applications to materials science in Chapter 1, the mathematical theory of Bayesian optimization is outlined in Chapter 2. Finally, Chapter 3 discusses an application of Bayesian optimization to a complicated structure optimization problem in computational surface science. Bayesian optimization is a promising global optimization technique that originates in the field of machine learning and is starting to gain attention in materials science. For the purpose of materials design, Bayesian optimization can be used to predict new materials with novel properties without extensive screening of candidate materials. For the purpose of computational materials science, Bayesian optimization can be incorporated into first-principles calculations to perform efficient, global structure optimizations. While research in these directions has been reported in high-profile journals, until now there has been no textbook aimed specifically at materials scientists who wish to incorporate Bayesian optimization into their own research. This book will be accessible to researchers and students in materials science who have a basic background in calculus and linear algebra.
Bayesian Spatial Modelling with Conjugate Prior Models
by Henning Omre Torstein M. Fjeldstad Ole Bernhard ForbergThis book offers a comprehensive overview of statistical methodology for modelling and evaluating spatial variables useful in a variety of applications. These spatial variables fall into three categories: continuous, like terrain elevation; events, like tree locations; and mosaics, like medical images. Definitions and discussions of random field models are included for each of these three previously mentioned spatial variable types. Moreover, the readers will have access to algorithms suitable for applying this methodology in practical problem solving, and the computational efficiency of these algorithms are discussed. The presentation is made in a consistent predictive Bayesian framework, which allows separate modelling of the observation acquisition procedure, as a likelihood model, and of the spatial variable characteristics, as a prior spatial model. The likelihood and prior models uniquely define the posterior spatial model, which provides the basis for spatial simulations, spatial predictions with associated precisions, and model parameter inference. The emphasis is on Bayesian spatial modelling with conjugate pairs of likelihood and prior models that are analytically tractable and hence suitable for data abundant spatial studies. Alternative methods frequently used in spatial statistics are presented using a unified notation. The book is suitable as a textbook for a ‘Spatial Statistics’ course at the MSc or PhD level, as it also includes algorithm descriptions, project texts, and exercises.
Bayou Dilemma: Louisiana in Crisis and Change (America's Third Coast Series)
by Samuel C. HydeContributions by Janet Allured, Craig E. Colten, Marcus S. Cox, Pearson Cross, John Bel Edwards, Adam Fairclough, Keith M. Finley, Samuel C. Hyde Jr., John A. Lopez, and Robert Mann In the fall of 2022, a diverse group of scholars including scientists, historians, political scientists, geographers, and journalists, along with Governor John Bel Edwards, gathered to present views on the challenges that define life in Louisiana. Born out of the symposium, Bayou Dilemma: Louisiana in Crisis and Change is an unprecedented compilation that examines the social, political, environmental, and economic hurdles pervasive to the Gulf South and especially the Bayou State. The essays collected in the volume illuminate pressing problems confronting Louisiana and its surrounding environs, as well as some of the least known and most frequently misunderstood issues that have affected the state in the past. Topics include the problems of flood control, unequal treatment for African Americans and women, political corruption, endemic violence, and partisan applications of justice, as well as the crisis of coastal erosion, the dilemma of special interests shaping legislation, and the corresponding drain of talent from the state to regions offering improved opportunities. The anthology is a provocative and essential guide that reveals how such trials emerged, how they were overcome or managed, and how they continue to shape the Gulf South’s regional identity. Concentrating on the future well-being of the state and its occupants, the volume suggests fresh pathways for addressing these lingering concerns.
Bayou D’Arbonne Swamp: A Naturalist’s Memoir of Place
by Kelby OuchleyBayou D’Arbonne Swamp addresses the vibrant natural, cultural, and social history of a north Louisiana swamp. Kelby Ouchley grew up near Bayou D’Arbonne Swamp, and he later spent much of his professional life as a wildlife biologist and naturalist overseeing the national wildlife refuge created from much of the area. His deep personal and professional connections to the landscape give him valuable insight into the enormous changes that have struck the swamp over the last century and the reasons behind this transformation. In this fascinating narrative, Ouchley offers a kaleidoscopic view of Bayou D’Arbonne Swamp that reveals its unique past and distinctive flora, fauna, and people. Although these are stories of a particular swamp, they tell us much about issues facing other wetlands, as well as prairies, mountains, and deserts, when viewed through an ecological, social, and historical lens. Ouchley aims to foster an awareness of the environmental impacts of human decisions that encourages readers to consider ecological choices in their daily lives. The result is a work that presents an intimate and multilayered natural history of Bayou D’Arbonne Swamp that extends beyond the edges of the ever-changing Louisiana wetland, informing the environmental history of Louisiana, conservation, and ecological change.
Bayou Harvest: Subsistence Practice in Coastal Louisiana (America's Third Coast Series)
by Helen A. Regis Shana WaltonTo inhabitants of the Gulf Coast region of Louisiana, food is much more than nourishment. The acts of gathering, preparing, and sharing food are ways to raise children, bond with friends, and build community. In Bayou Harvest: Subsistence Practice in Coastal Louisiana, Helen A. Regis and Shana Walton examine how coastal residents deploy self-reliance and care for each other through harvesting and sharing food. Pulling from four years of fieldwork and study, Walton and Regis explore harvesting, hunting, and foraging by Native Americans, Cajuns, and other Bayou residents. This engagement with Indigenous thinkers and their neighbors yields a multifaceted view of subsistence in Louisiana. Readers will learn about coastal residents’ love for the land and water, their deep connections to place, and how they identify with their food and game heritage. The book also delves into their worries about the future, particularly storms, pollution, and land loss in the coastal region. Using a set of narratives that documents the everyday food practices of these communities, the authors conclude that subsistence is not so much a specific task like peeling shrimp or harvesting sassafras, but is fundamentally about what these activities mean to the people of the coast. Drawn together with immersive writing, this book explores a way of life that is vibrant, built on deep historical roots, and profoundly threatened by the Gulf’s shrinking coast.
Bayshore Summer: Finding Eden in a Most Unlikely Place
by Pete DunneBypassed by time and &“Joisey&” Shore–bound vacationers, the marshes and forests of the Bayshore constitute one of North America&’s last great undiscovered wild places. Sixty million people live within a tank of gas of this environmentally rich and diverse place, yet most miss out on the region&’s amazing spectacles. Bayshore Summer is a bridge that links the rest of the world to this timeless land. Pete Dunne acts as ambassador and tour guide, following Bayshore residents as they haul crab traps, bale salt hay, stake out deer poachers, and pick tomatoes. He examines and appreciates this fertile land, how we live off it and how all of us connect with it. From the shorebirds that converge by the thousands to gorge themselves on crab eggs to the delicious fresh produce that earned the Garden State its nickname, from the line-dropping expectancy of party boat fishing to the waterman who lives on a first-name basis with the birds around his boat, Bayshore Summer is at once an expansive and intimate portrait of a special place, a secret Eden, and a glimpse into a world as rich as summer and enduring as a whispered promise.

Beach Politics: Social, Racial, and Environmental Injustice on the Shoreline
by Setha LowExplores how elites restrict access to public beaches around the globeBeaches are a beloved form of public space. Yet there has been an alarming global trend of restricting access to public sections of beaches to ensure that waterfront property owners can enjoy the shoreline exclusively or develop the land for commercial use.Beach Politics examines how over the past forty years, privatization of public space has accelerated with the help of both local governments and national corporations. On a local level, this can entail a group of wealthy neighbors purposely blocking off public beach access in their neighborhood: hiring security guards, building fences, or putting up “No Trespassing” signs to turn away members of the public who have every right to be there. On a state or national level, it can manifest as gated communities owned by private corporations sectioning off huge swaths of land, limiting access, or governments promoting private, rather than public, development along the shoreline. Whenever disputes about land use arise, the powers that be often side with private interests and the wealthy over those with fewer resources and, frequently, people of color. With the continuing threat of climate change, decisions about how and where to harden or protect the shoreline often limits public use.Focused on beaches, access to public space, and social justice, this book brings together powerful contributions illustrating how these issues are inextricably bound with socioeconomic status, racial segregation, and climate justice. Together they highlight how, through illegal actions and exclusionary legislation, the beach can be transformed from “a strip of nature” into a palimpsest of greed, racism, ecological disregard, and socioeconomic discrimination.
Beach Processes and Nearshore Hydrodynamics of Dhanushkodi, Rameswaram, India (Springer Oceanography)
by Usha Natesan R. VishnunathThis book focuses on understanding the shoreline dynamics, nearshore processes and sediment transport around Rameswaram Island and the cities of Dhanushkodi and Arichamunai. Rameswaram Island is located between the Gulf of Mannar on the south and Palk Bay on the north, between the southern tip of India and Sri Lanka, and is unique in terms of physical, chemical and biological processes. The Gulf of Mannar is established as a marine biodiversity conservation area by its richness of variety and variability of marine species such as corals, finfish, shellfish and other fishes. The island is predominantly influenced by four seasons: northeast monsoon, post-monsoon, summer and southwest monsoon; and the sedimentological and hydrodynamic conditions significantly change seasonally, resulting in the island’s responding in a different manner with each season. It also explains the physical forces and their impacts around these areas. Rameswaram Island has existed naturally for a long period of time even under the influence of different water masses of the Gulf of Mannar and Palk Bay. Understanding the regional natural phenomena is the only solution to carry out the best management practices to develop coastal constructions and modifications.
Beach Renourishment (SpringerBriefs in Earth Sciences)
by Eric Bird Nick LewisBeach renourishment is the restoration of beaches that have been depleted. The text deals with the sources of beach sediment as well as the causes and typical responses to beach erosion, before discussion of beach renourishment. Some of the first documented renourishment projects were undertaken in the early 1900's on the east coast of the United States. Several countries have since renourished beaches, particularly during the past few decades. Most projects have been in the United States, the United Kingdom, some European countries and Australia. These are reviewed and experience from various beach renourishment projects used for discussion of the following topics: 1. The need for preliminary investigations 2. Sources of sediment for beach renourishment 3. Methods of beach renourishment 4. Design considerations 5. Monitoring changes after beach renourishment 6. Assessment of performance 7. Modelling of beach renourishment 8. Beach renourishment for coast protection 9. Environmental impacts 10. Costs and benefits 11. Response of renourished beaches to a rising sea level
Beach and Dune Restoration
by Karl F. NordstromThis new edition - now with Nancy Jackson as a co-author - continues the themes of the first edition: the need to restore the biodiversity, ecosystem health, and ecosystem services provided by coastal landforms and habitats, especially in the light of climate change. The second edition reports on progress made on practices identified in the first edition, presents additional case studies, and addresses new and emerging issues. It analyzes the tradeoffs involved in restoring beaches and dunes - especially on developed coasts - the most effective approaches to use, and how stakeholders can play an active role. The concept of restoration is broad, and includes physical, ecological, economic, social, and ethical principles and ideals. The book will be valuable for coastal scientists, engineers, planners, and managers, as well as shorefront residents. It will also serve as a useful supplementary reference textbook in courses dealing with issues of coastal management and ecology.

Beam Diagnostics in Superconducting Accelerating Cavities: The Extraction of Transverse Beam Position from Beam-Excited Higher Order Modes (Springer Theses)
by Pei ZhangAn energetic charged particle beam introduced to an rf cavity excites a wakefield therein. This wakefield can be decomposed into a series of higher order modes and multipoles, which for sufficiently small beam offsets are dominated by the dipole component. This work focuses on using these dipole modes to detect the beam position in third harmonic superconducting S-band cavities for light source applications. A rigorous examination of several means of analysing the beam position based on signals radiated to higher order modes ports is presented. Experimental results indicate a position resolution, based on this technique, of 20 microns over a complete module of 4 cavities. Methods are also indicated for improving the resolution and for applying this method to other cavity configurations. This work is distinguished by its clarity and potential for application to several other international facilities. The material is presented in a didactic style and is recommended both for students new to the field, and for scientists well-versed in the field of rf diagnostics.
Bear River: Last Chance to Change Course
by Craig DentonCraig Denton notes, “Water will be the primary political, social, and economic issue in the Intermountain West in the twenty-first century. ” Urban Utah thirsts for the Great Salt Lake principal source, the Bear River. Plans abound to divert it for a rapidly growing Wasatch Front, as the last good option for future water. But is it? Who now uses the river and how? Who are its stakeholders? What does the Bear mean to them? What is left for further use? How do we measure the Bear's own interest, give it a voice in decisions? Craig Denton's documentary takes on these questions. He tells the story of the river and the people, of many sorts, with diverse purposes, who live and depend on it. Bear River begins in alpine snowfields, lakes, and creeks in the Uinta Mountains, flows north through Wyoming, loops south in Idaho, and enters the inland sea by way of the an environmentally critical bird refuge. Along the way it has many uses: habitat, farms, electricity, recreation, lawns and homes. Denton researches the natural and human history of the river, photographed it, interviewed many stakeholders, and tried to capture the river perspective. His photographs, printed as crisp duotones, carry us downstream, ultimately to big questions, begging to be answered soon, about what we should and can make of the Bear River. Denton writes, Gravity my engine, Water my soul. I am the teller of life and deep time. You would measure me. Sever me. Own me. In your name. Let me flow In your imagination That I may speak.

Bears of the North: A Year Inside Their Worlds
by Wayne LynchAn unprecedented visual and scientific journey into the secret world of bears.In Bears of the North, renowned wildlife photographer, naturalist, and bestselling author Wayne Lynch offers us a work of scintillating science and stunning beauty. Following polar bears, brown bears, and American and Asiatic black bears through the seasons, this journey is an insider's view of hibernation's mysteries and the birth of cubs in winter; the mating rituals and voracious appetites of spring; hunting, fishing, and encounters with neighbors during summer; and the feeding frenzy and exuberant play of autumn. Dispelling the stereotypes and untruths—but none of the magic—surrounding these magnificent animals, Lynch comments on the latest scientific discoveries related to the biology, behavior, and ecology of bears. He describes how satellite telemetry has revealed the purpose behind the meanderings of bears and the great distances they sometimes cover on land and in water. He also shows how DNA analysis can teach us about the relatedness of bears within a population, even revealing the identity of a particular cub's father. Taking us out into the wilds of the tundra and forests to share his firsthand observations of the marvelous bears of the Northern Hemisphere, Lynch describes their survival strategies and the threats they face from habitat fragmentation and global climate change. Lynch's fascinating narrative is enhanced by over 150 gorgeous, original color photographs that capture bears in their habitats, including appearances of the elusive moon bear, fierce polar bear battles, and rare images of mothers' intimate moments with their cubs. Informed by Lynch's nearly forty years of experience observing and photographing bears in the wild, and aided by sophisticated digital photo technologies, Bears of the North is an unrivaled collection of enthralling and informative portraits of bears in their natural environments.
Bears of the World: Ecology, Conservation and Management
by Mario Melletti Vincenzo PenterianiBears have fascinated people since ancient times. The relationship between bears and humans dates back thousands of years, during which time we have also competed with bears for shelter and food. In modern times, bears have come under pressure through encroachment on their habitats, climate change, and illegal trade in their body parts, including the Asian bear bile market. The IUCN lists six bears as Vulnerable or Endangered, and even the Least Concern species, such as the brown bear, are at risk of extirpation in certain countries. The poaching and international trade of these most threatened populations are prohibited, but still ongoing. Covering all bear species worldwide, this beautifully illustrated volume brings together the contributions of 200 international bear experts on the ecology, conservation status, and management of the Ursidae family. It reveals the fascinating long history of interactions between humans and bears and the threats affecting these charismatic species.
Bears: The Mighty Grizzlies of the West
by Julie ArgyleThe mighty North American brown bear, most often referred to as the grizzly, is an iconic symbol of power and strength. Mostly found in the Western United States and Canada, the still-endangered bruin has made strides into a tenuous sustainability. The strikingly beautiful photography, and the essay woven through the pages of Bears: The Mighty Grizzlies of the West, showcases this beautiful, smart, and incredible species. Julie Argyle explores their behavior, their family dynamics, and what it means to be a grizzly in the wilderness of the greater Yellowstone area. She includes stories about individual bears: Raspberry and Snow, The Beryl Sow, The Obsidian Sow, Snaggletooth, and 791 (a famous boar), and looks at the issues of increasing conflicts between humans and the grizzlies and what the future holds for them.
