This book discusses all spacecraft attitude control-related topics: spacecraft (including attitude measurements, actuator, and disturbance torques), modeling, spacecraft attitude determination and estimation, and spacecraft attitude controls. Unlike other books addressing these topics, this book focuses on quaternion-based methods because of its many merits. The book lays a brief, but necessary background on rotation sequence representations and frequently used reference frames that form the foundation of spacecraft attitude description. It then discusses the fundamentals of attitude determination using vector measurements, various efficient (including very recently developed) attitude determination algorithms, and the instruments and methods of popular vector measurements. With available attitude measurements, attitude control designs for inertial point and nadir pointing are presented in terms of required torques which are independent of actuators in use. Given the required control torques, some actuators are not able to generate the accurate control torques, therefore, spacecraft attitude control design methods with achievable torques for these actuators (for example, magnetic torque bars and control moment gyros) are provided. Some rigorous controllability results are provided. The book also includes attitude control in some special maneuvers, such as orbital-raising, docking and rendezvous, that are normally not discussed in similar books. Almost all design methods are based on state-spaced modern control approaches, such as linear quadratic optimal control, robust pole assignment control, model predictive control, and gain scheduling control. Applications of these methods to spacecraft attitude control problems are provided. Appendices are provided for readers who are not familiar with these topics.
Aspects of the biogeochemistry of estuaries from a variety of environments, from the tropics to the Arctic, are discussed. In most cases the courses of these rivers have been altered by dams or diversions; the results of these changes on the nature of the estuary are also discussed, where such data is available. In the case of the Tasmanian rivers, the estuary of the Huon, a largely untouched river, is contrasted with that of the Derwent, a river heavily influenced by industry. The future state of all of these estuaries may be a sensitive indicator of shifts in global weather patterns.
Ecological assessments are a critical component of land management planning and regulatory decision-making. In the United States, for example, the National Environmental Policy Act of 1969 directs that the environmental consequences associated with proposed management of federal lands be fully disclosed to the general public through environmental impact assessments. In a similar manner, over 40 other countries have legislated the use of some type of ecological assessment as a prerequisite for effective environmental planning and land management. Although ecological assessments can be conducted at a variety of spatial scales and may address one or many issues, the main intent of this book is to describe topics with particular importance to strategic integrated ecological assessments at a regional or subregional scale. The chapters in this book range from overviews of basic ecological principles, to suggestions concerning ecosystem characterization and analysis, to systematic reviews of selected case studies. In this respect, the book provides both theoretical and practical advice for future ecological assessments given specific land use planning objectives. This book will be the reference standard for any person engaged in any ecological assessment exercise at any level, whether they work for national, state or regional authorities or in academia.
The field of endocrine disruption or endocrine active compounds (EACs), which is just emerging and still controversial, is comprehensively covered by leading experts in Volume 3, Subvolumes L (Part I) and M (the present volume, Part II). The major classes of endocrine active chemicals are discussed, as well as methods for their detection and their association with health disturbances in humans and wildlife. The etiology of several of the human diseases associated with endocrine disruptors, e.g. breast and prostate cancer, decreased fertility and malformations, is still poorly understood, and the current state of knowledge is presented. Since hormonally active agents appear to have the potential of both adverse and beneficial effects, the evidence of health benefits associated with endocrine active compounds in humans is also presented. Basic chapters on the mode of action of EACs and on the etiology of the associated diseases facilitate the understanding of this complex subject for non-medical readers.
Human activity has more than doubled the rate of creation of reactive nitrogen on the land surface of the earth over natural levels, with much of this change occurring in recent decades. Major drivers behind this increase are population growth, agricultural intensification, and emissions of nitrogen pollutants to the atmosphere from the combustion of fossil fuels. As a result, nitrogen is accumulating in the landscape and in water at unprecedented levels, and is connected to a host of environmental problems including effects on natural ecosystems and on human health. For example, eutrophication caused by excessive inputs of N from landscapes to the oceans is one of the greatest factors altering water quality in coastal ecosystems worldwide. This synthesis is the final report from the International SCOPE Project on Nitrogen Transport and Transformations: A Regional and Global Analysis. SCOPE (the Scientific Committee on Problems of the Environment) authorized the Nitrogen Project because of the need to better understand how humans have altered nitrogen cycling globally and at the scale of large regions. The project has synthesized information through a series of workshops over the past 8 years, involving over 250 scientists from over 20 different nations. Papers in this volume explore the extent to which human activity has affected the nitrogen cycle in terrestrial regions and in the world's oceans, and discuss the implications of accelerated nitrogen cycling for nature and society.
Photochemical reactions play a major role in the environment including a wide range of reactions in the atmosphere, natural waters, soil and living organisms. This new volume on Environmental Photochemistry up-dates the previous edition with chapters on basic aspects including concepts of photochemical transformations and mechanistic photochemical processes in the atmosphere and water. In addition a range of applications are also detailed such as advanced photochemical oxidation processes for water and air treatment as well as applications of photocatalysis for surface treatment and nuclear fuel reprocessing. The new edition provides a critical up to date overview of the most important research in the field of environmental photochemistry.
This volume examines the environmental issues currently under debate in the international arena. The text approaches the topic at a conceptual level, and from an interdisciplinary viewpoint. It analyses the roles of key players in environmental policy, the nation state, non-governmental organizations and the business community. It continues with an examination of the importance of international relations (trade, east, west, north, south), and goes on to consider the prospects for sustainable development and social changes required for sustainable development to become a reality.
Volume two considers major environmental issues using individual
case studies from around the world as illustrations. These case
studies explore the causes of international environmental issues
and investigate the conflicts that hamper these solutions. The case
studies address such problems as intensive farming, overpopulation,
deforestation, climate change and waste disposal. Each case study
also looks at policy and management of these international
environmental issues. The case studies span the globe, encompassing
the Western world as well as the former Eastern Bloc and developing
countries in Africa and South East Asia.
This book explores the complex problem of how to measure the 'success' of social organisations, projects and activities. Whether improving a local situation, organizing a campaign around sustainability, or assessing the intangible effects of perceived social benefits, currently we have only have a very limited range of mechanisms for judging effectiveness. On the one hand, a market-driven logic demands that qualitative perceptions and experiences are quantified into simplified and numerically defined variables. On the other, community projects are left un-assessed, as one-off outcomes of local and situated processes that must somehow automatically 'make things better'. For academics, researchers and other professionals working in this field this has resulted in the deep frustration of not being able to assess the things that are most centrally important: higher human values such as integrity, trust, respect, equality and social justice. Measuring Intangible Values argues that we can make shared social values - and their measurement - central to decisions about improving civil society. But because these social values are intangible, we need to develop ways of eliciting and validating them at the local level that can capture people's shared meanings across multiple goals and perspectives. We need to develop mechanisms for evaluating whether these values are met that use rigorous but also relevant measures. And we need to develop ways of doing this that are scalable, transferable and comparable across different kinds of organisations and fields of activity. This book will be valuable for researchers in all social science disciplines which touch on human values, such as sociology, social psychology, human geography, social policy, architecture and planning, design and community studies.

This book discusses UV radiation, its effects on ecosystems and the likely evolutionary consequences of changed UV radiation environments, past, present and future. The first two chapters examine the history of the UV radiation climate of earth and the factors that determine organismal and ecosystem exposure. Their purpose is to give the reader a physical perspective on UV radiation and an understanding of the constantly changing UV environment that ecosystems are exposed to over time. Variations in the UV radiation environment occur at the local level (such as boundary layer and plant canopy effects) through to global-scale changes (such as alterations in the column abundance of UV-B protecting ozone). UV radiation regimes also vary over temporal scales. These alterations occur on time scales of seconds (the movement of clouds and plant canopies) to literally billions of years (gross long-term changes in the composition of the Earth's atmosphere). In the chapters that follow five specific biological and ecological topics in photobiology are considered. They are effects of UV radiation on amphibians, plants, corals, aquatic microbial ecosystems and Antarctic ecosystems that are exposed to the anthropogenically generated ozone 'hole'. These chapters consider UV radiation effects at a diversity of levels from the biochemical to the community. Their purpose is to provide the reader with our current understanding of the ecological effects of UV radiation, the areas where questions still remain and to provide a perspective from which the reader can better understand questions in evolutionary photobiology. The final chapter investigates the biological consequences of altered extraterrestrial ultraviolet fluxes, which are quite different from those experienced on the Earth. Our knowledge of the role of UV radiation in shaping ecologies and evolutionary change is still in its infancy. This book brings together a number of authors with the aim of helping to consolidate a better understanding of this interesting area of photobiology.
Energy is central to the fabric of society. This book revisits the classic notions of energy impacts by examining the social effects of resource extraction and energy projects which are often overlooked. Energy impacts are often reduced to the narrow configurations of greenhouse gas emissions, chemical spills or land use changes. However, this neglects the fact that the way we produce, distribute and consume energy shapes society, political institutions and culture. The authors trace the impacts of contemporary energy and resource extraction developments and explain their significance for the shaping of powerful social imaginaries and a reconfiguration of political and democratic systems. They analyse not only the complex histories and landscapes of industrial mining and energy development, including oil, coal, wind power, gas (fracking) and electrification, but also their significance for contested energy and social futures. Based on ethnographic and interdisciplinary research from around the world, including case studies from Australia, Germany, Kenya, the Netherlands, Nicaragua, Norway, Poland, Turkey, UK and USA, they document the effects on local communities and how these are often transformed into citizen engagement, protest and resistance. This sheds new light on the relationship between energy and power, reflecting a wide array of pertinent impacts beyond the usual considerations of economic efficiency and energy security. The volume is aimed at advanced students and researchers in anthropology, sociology, human geography, science and technology studies, environmental studies and sustainable development as well as professionals working in the field of impact assessments.
The history of gears with asymmetric teeth is not sufficiently recorded in modern gear literature, with some gear researchers concluding that asymmetric tooth gears were discovered just several decades ago. This book sheds light upon the origins and state of asymmetric gearing, referencing technical articles from the 19th, 20th, and 21st centuries. As a practicing gear engineer with over 40 years' experience, author Alexander L. Kapelevich has successfully implemented asymmetric gears in a variety of custom gear transmissions. This book addresses all aspects of asymmetric gear development, including theoretical fundamentals; tooth geometry optimization; stress analysis and rating; design and production specifics; analytical and experimental comparison to the best symmetric gears; and application examples. Readers are encouraged to look beyond the status quo established by traditional gear design, and to apply principles of asymmetric gearing to actual gear design. Optimal solutions are presented for gear drives that will maximize technical performance and marketability. Features Presents a state-of the-art, comprehensive historical overview of asymmetric gearing Explains the Direct Gear Design (R) approach to asymmetric gear design Describes asymmetric tooth gear geometry optimization, areas of existence, and parameter selection limits Considers practical aspects of asymmetric gear fabrication and measurement Presents analytical and experimental comparison of asymmetric gears to advanced symmetric gears, showing the advantages of asymmetric designs Provides numerous real-world examples of asymmetric gear application
Cosmogenic radionuclides are radioactive isotopes which are produced by natural processes and distributed within the Earth system. With a holistic view of the environment the authors show in this book how cosmogenic radionuclides can be used to trace and to reconstruct the history of a large variety of processes. They discuss the way in which cosmogenic radionuclides can assist in the quantification of complex processes in the present-day environment. The book aims to demonstrate to the reader the strength of analytic tools based on cosmogenic radionuclides, their contribution to almost any field of modern science, and how these tools may assist in the solution of many present and future problems that we face here on Earth. The book provides a comprehensive discussion of the basic principles behind the applications of cosmogenic (and other) radionuclides as environmental tracers and dating tools. The second section of the book discusses in some detail the production of radionuclides by cosmic radiation, their transport and distribution in the atmosphere and the hydrosphere, their storage in natural archives, and how they are measured. The third section of the book presents a number of examples selected to illustrate typical tracer and dating applications in a number of different spheres (atmosphere, hydrosphere, geosphere, biosphere, solar physics and astronomy). At the same time the authors have outlined the limitations of the use of cosmogenic radionuclides. Written on a level understandable by graduate students without specialist skills in physics or mathematics, the book addresses a wide audience, ranging from archaeology, biophysics, and geophysics, to atmospheric physics, hydrology, astrophysics and space science.

The Water Research Institute at the Technion (Israel Institute of Technology) is proud to have initiated and sponsored the International Workshop "Soil and Aquifer Pollution: Non-Aqueous Phase Liquids - Contamination and Recla- tion," held May 13th-15th, 1996, on the Technion campus in Haifa. Groundwater contamination is one of the pressing issues facing Israel and other countries which depend on groundwater for water supply. In Israel, 60% of the water supply comes from groundwater, most of it from two large aquifers. The Coastal Aquifer underlies the area where the largest concentration of human activity already takes place, and where much of future development is expected to occur. It is a phreatic sandstone aquifer, vulnerable to pollution from activities at the surface. The Mountain Aquifer is recharged in the higher terrain to the east, and flows, first in a phreatic zone, then confined, westward and underneath the Coastal Aquifer. This limestone aquifer has higher permeabilities and flow velo- ties, so pollution can reach the groundwater quite readily. Smaller local aquifers are also important components in the national water system. While measures are taken to protect these aquifers from pollution, there are locations where contamination has already occurred. Furthermore, accidental pollution may not be totally avoided in the future. Therefore, understanding the processes of groundwater contamination, recommending the proper measures for preventing it, and determining the best means for reclamation once pollution has occurred, are of great practical importance. Non-aqueous phase liquids (NAPLs) are among the most significant contaminants.
This book describes a cross-domain architecture and design tools for networked complex systems where application subsystems of different criticality coexist and interact on networked multi-core chips. The architecture leverages multi-core platforms for a hierarchical system perspective of mixed-criticality applications. This system perspective is realized by virtualization to establish security, safety and real-time performance. The impact further includes a reduction of time-to-market, decreased development, deployment and maintenance cost, and the exploitation of the economies of scale through cross-domain components and tools. Describes an end-to-end architecture for hypervisor-level, chip-level, and cluster level. Offers a solution for different types of resources including processors, on-chip communication, off-chip communication, and I/O. Provides a cross-domain approach with examples for wind-power, health-care, and avionics. Introduces hierarchical adaptation strategies for mixed-criticality systems Provides modular verification and certification methods for the seamless integration of mixed-criticality systems. Covers platform technologies, along with a methodology for the development process. Presents an experimental evaluation of technological results in cooperation with industrial partners. The information in this book will be extremely useful to industry leaders who design and manufacture products with distributed embedded systems in mixed-criticality use-cases. It will also benefit suppliers of embedded components or development tools used in this area. As an educational tool, this material can be used to teach students and working professionals in areas including embedded systems, computer networks, system architecture, dependability, real-time systems, and avionics, wind-power and health-care systems.
