Hydrometrie
by Gerd MorgenschweisDie Kenntnis der in einem Gewässer (Fluss, Kanal) fließenden Wassermenge und ihrer räumlichen und zeitlichen Varianz ist eine wesentliche Grundlage für die Bemessung von Wasserbauwerken sowie die rationale Bewirtschaftung der Ressource Wasser. Um das pro Zeiteinheit durchfließende Wasservolumen, den Durchfluss, messtechnisch zu erfassen, gibt es seit Jahrhunderten eingesetzte traditionelle Verfahren, aber auch in den letzten Jahren vermehrt "neue" Messverfahren, die aufgrund des zunehmenden Einsatzes von Elektronik in der Mess- und Regeltechnik möglich geworden sind. Aufbauend auf den physikalischen Grundlagen behandelt der Autor die Möglichkeiten und Grenzen der einzelnen Messverfahren, bei ihrem Einsatz unter den rauen Umweltbedingungen von Feldmessungen in kleinen und großen Flüssen sowie in Zu- und Abläufen von Kläranlagen. Anhand von Beispielen aus der nationalen und internationalen Messpraxis sowie mit ausgeführten Berechnungsbeispielen werden Kriterien für die Wahl der geeigneten Messtechnik aufgezeigt. Der Leser findet viele Lösungsmöglichkeiten für konkrete Fragestellungen.
Hydropolitics: The Itaipu Dam, Sovereignty, and the Engineering of Modern South America (Princeton Studies in Culture and Technology #20)
by Professor Christine FolchAn in-depth look at the people and institutions connected with the Itaipu Dam, the world’s biggest producer of renewable energyHydropolitics is a groundbreaking investigation of the world’s largest power plant and the ways the energy we use shapes politics and economics. Itaipu Binational Hydroelectric Dam straddles the Paraná River border that divides the two countries that equally co-own the dam, Brazil and Paraguay. It generates the carbon-free electricity that powers industry in both the giant of South America and one of the smallest economies of the region. Based on unprecedented access to energy decision makers, Christine Folch reveals how Paraguayans harness the dam to engineer wealth, power, and sovereignty, demonstrating how energy capture influences social structures.During the dam’s construction under the right-wing military government of Alfredo Stroessner and later during the leftist presidency of liberation theologian Fernando Lugo, the dam became central to debates about development, governance, and prosperity. Dams not only change landscapes; Folch asserts that the properties of water, transmuted by dams, change states. She argues that the dam converts water into electricity and money to produce hydropolitics through its physical infrastructure, the financial liquidity of energy monies, and the international legal agreements managing transboundary water resources between Brazil and Paraguay, and their neighbors Argentina, Bolivia, and Uruguay.Looking at the fraught political discussions about the future of the world’s single largest producer of renewable energy, Hydropolitics explores how this massive public works project touches the lives of all who are linked to it.
Hydroponics and Environmental Bioremediation: Wastewater Treatment (Springer Water)
by Nitish KumarBioremediation is the use of biological interventions for mitigation of the noxious effects caused by pollutants in the environment including wastewater. It is very useful approach for a variety of applications in the area of environmental protection. It has become an attractive alternative to the conventional clean-up technologies that employ plants and their associated microorganisms to remove, contain, or render harmless environmental contaminants.Hydroponic systems, which utilize plants which are grown in a nutrient solution without soil, are expanding and raising great interest in the commercial and scientific community. They are engineered systems designed and constructed to utilize the natural processes involving macrophytes, media, and the associated microbial assemblages to assist in treating wastewaters. This is a relatively new approach in wastewater treatment by which a variety of emergent macrophytes are grown hydroponically on top of floating platforms with their roots developing freely into the flowing wastewater. The roots provide a support medium for attached microbial growth which participates in the treatment process.

Hydropower in the New Millennium: Proceedings of the 4th International Conference Hydropower, Bergen, Norway, 20-22 June 2001
by Bjørn Honningsvåg Grethe Holm Midttømme Kjell Repp Kjetil Arne Vaskinn Trond WesterenThe power sector has undergone a liberalization process both in industrialized and developing countries, involving market regimes, as well as ownership structure. These processes have called for new and innovative concepts, affecting both the operation of existing hydropower plants and transmission facilities, as well as the development and implementation of new projects. At the same time a sharper focus is being placed on environmental considerations. In this context it is important to emphasize the obvious benefits of hydropower as a clean, renewable and sustainable energy source. It is however also relevant to focus on the impact on the local environment during the planning and operation of hydropower plants. New knowledge and methods have been developed that make it possible to mitigate the local undesirable effects of such projects. Development and operation of modern power systems require sophisticated technology. Continuous research and development in this field is therefore crucial to maintaining hydropower as a competitive and environmentally well-accepted form of power generation.
Hydropower Screws: Calculation and Optimal Design of Archimedean Screws
by Dirk Michael NuernbergkWater screw conveyors have been in use for centuries. Their invention is attributed to Archimedes. However, the idea of using this Archimedean screw also as a hydropower screw to convert hydraulic energy into electrical energy did not emerge until the 1990s. More recently, hydropower screws have been used very frequently at hydropower sites and have now also attracted increasing interest from scientists and users worldwide. This is due to the machine's very good efficiency, it's simple and inexpensive design, and its fish compatibility. This book provides calculation fundamentals for hydropower screws. The author focuses on the description of the hydraulic processes and gives a design flow that can be used to design hydropower screws. The hydraulic behavior, dimensions, speed, efficiency, forces acting on the screw such as sag or lift, as well as the arrangement of the gearbox and the choice of generator are discussed. The theoretical equations, some of which are newly derived, are applied using examples. Finally, a design flow is given that can be used to easily adapt an optimally designed hydropower screw to a location. New findings presented in various scientific publications have been incorporated into the translation of the second German edition. In addition, experiments were carried out at different locations, which led to a better understanding of the available data basis. This has allowed the theoretical predictions of this book to be confirmed experimentally. In addition, the author has investigated a number of faulty installations and has been involved in the design of successful working waterpower plants equipped with hydropower screws.

Hyperbolic Conservation Laws and the Compensated Compactness Method
by Yunguang LuThe method of compensated compactness as a technique for studying hyperbolic conservation laws is of fundamental importance in many branches of applied mathematics. Until now, however, most accounts of this method have been confined to research papers. Offering the first comprehensive treatment, Hyperbolic Conservation Laws and the Compensated Comp
Hyperbolic Triangle Centers: The Special Relativistic Approach
by A. A. UngarAfter A. Ungar had introduced vector algebra and Cartesian coordinates into hyperbolic geometry in his earlier books, along with novel applications in Einstein's special theory of relativity, the purpose of his new book is to introduce hyperbolic barycentric coordinates, another important concept to embed Euclidean geometry into hyperbolic geometry. It will be demonstrated that, in full analogy to classical mechanics where barycentric coordinates are related to the Newtonian mass, barycentric coordinates are related to the Einsteinian relativistic mass in hyperbolic geometry. Contrary to general belief, Einstein's relativistic mass hence meshes up extraordinarily well with Minkowski's four-vector formalism of special relativity. In Euclidean geometry, barycentric coordinates can be used to determine various triangle centers. While there are many known Euclidean triangle centers, only few hyperbolic triangle centers are known, and none of the known hyperbolic triangle centers has been determined analytically with respect to its hyperbolic triangle vertices. In his recent research, the author set the ground for investigating hyperbolic triangle centers via hyperbolic barycentric coordinates, and one of the purposes of this book is to initiate a study of hyperbolic triangle centers in full analogy with the rich study of Euclidean triangle centers. Owing to its novelty, the book is aimed at a large audience: it can be enjoyed equally by upper-level undergraduates, graduate students, researchers and academics in geometry, abstract algebra, theoretical physics and astronomy. For a fruitful reading of this book, familiarity with Euclidean geometry is assumed. Mathematical-physicists and theoretical physicists are likely to enjoy the study of Einstein's special relativity in terms of its underlying hyperbolic geometry. Geometers may enjoy the hunt for new hyperbolic triangle centers and, finally, astronomers may use hyperbolic barycentric coordinates in the velocity space of cosmology.
Hyperconsumption: Corporate Marketing vs. the Planet
by Gerard HastingsDiving deep into the world of corporate marketing, this incisive and eye-opening work shows how, in the hands of the corporation, business has become manipulative, divisive and disastrously at odds with the needs of the natural world. It calls on us to rethink and rebel. The corporate marketing blitz is driven by a simple economic truth: profits depend on demand always exceeding supply. A multi-billion-dollar global industry has therefore been created with the sole aim of turning us into devout consumers. Gerard Hastings invites us to explore alternatives to a system that is threatening our survival. He explores what it is to be human, how marketing can be used to do good rather than harm and the potential of alternative models that empower us to be citizens, not just consumers. Professionals and students in the business, marketing, public health, environmental and political sectors – as well as concerned citizens who know that business as usual is not an option – will value this accessible guide to what is going wrong with our current business models and how these failings can be addressed.
Hypernumbers and Extrafunctions
by Mark Burgin"Hypernumbers and Extrafunctions" presents a rigorous mathematical approach to operate with infinite values. First, concepts of real and complex numbers are expanded to include a new universe of numbers called hypernumbers which includes infinite quantities. This brief extends classical calculus based on real functions by introducing extrafunctions, which generalize not only the concept of a conventional function but also the concept of a distribution. Extrafucntions have been also efficiently used for a rigorous mathematical definition of the Feynman path integral, as well as for solving some problems in probability theory, which is also important for contemporary physics. This book introduces a new theory that includes the theory of distributions as a subtheory, providing more powerful tools for mathematics and its applications. Specifically, it makes it possible to solve PDE for which it is proved that they do not have solutions in distributions. Also illustrated in this text is how this new theory allows the differentiation and integration of any real function. This text can be used for enhancing traditional courses of calculus for undergraduates, as well as for teaching a separate course for graduate students.
Hyperobjects: Philosophy and Ecology after the End of the World (Posthumanities)
by Timothy MortonHaving set global warming in irreversible motion, we are facing the possibility of ecological catastrophe. But the environmental emergency is also a crisis for our philosophical habits of thought, confronting us with a problem that seems to defy not only our control but also our understanding. Global warming is perhaps the most dramatic example of what Timothy Morton calls &“hyperobjects&”—entities of such vast temporal and spatial dimensions that they defeat traditional ideas about what a thing is in the first place. In this book, Morton explains what hyperobjects are and their impact on how we think, how we coexist with one another and with nonhumans, and how we experience our politics, ethics, and art. Moving fluidly between philosophy, science, literature, visual and conceptual art, and popular culture, the book argues that hyperobjects show that the end of the world has already occurred in the sense that concepts such as world, nature, and even environment are no longer a meaningful horizon against which human events take place. Instead of inhabiting a world, we find ourselves inside a number of hyperobjects, such as climate, nuclear weapons, evolution, or relativity. Such objects put unbearable strains on our normal ways of reasoning. Insisting that we have to reinvent how we think to even begin to comprehend the world we now live in, Hyperobjects takes the first steps, outlining a genuinely postmodern ecological approach to thought and action.
Hyperparameter Tuning for Machine and Deep Learning with R: A Practical Guide
by Eva Bartz Thomas Bartz-Beielstein Martin Zaefferer Olaf MersmannThis open access book provides a wealth of hands-on examples that illustrate how hyperparameter tuning can be applied in practice and gives deep insights into the working mechanisms of machine learning (ML) and deep learning (DL) methods. The aim of the book is to equip readers with the ability to achieve better results with significantly less time, costs, effort and resources using the methods described here. The case studies presented in this book can be run on a regular desktop or notebook computer. No high-performance computing facilities are required. The idea for the book originated in a study conducted by Bartz & Bartz GmbH for the Federal Statistical Office of Germany (Destatis). Building on that study, the book is addressed to practitioners in industry as well as researchers, teachers and students in academia. The content focuses on the hyperparameter tuning of ML and DL algorithms, and is divided into two main parts: theory (Part I) and application (Part II). Essential topics covered include: a survey of important model parameters; four parameter tuning studies and one extensive global parameter tuning study; statistical analysis of the performance of ML and DL methods based on severity; and a new, consensus-ranking-based way to aggregate and analyze results from multiple algorithms. The book presents analyses of more than 30 hyperparameters from six relevant ML and DL methods, and provides source code so that users can reproduce the results. Accordingly, it serves as a handbook and textbook alike.
Hyperspace: A Scientific Odyssey Through Parallel Universes, Time Warps, and the Tenth Dimension
by Michio KakuAre there other dimensions beyond our own? Is time travel possible? Can we change the past? Are there gateways to parallel universes? All of us have pondered such questions, but there was a time when scientists dismissed these notions as outlandish speculations. Not any more. Today, they are the focus of the most intense scientific activity in recent memory. In Hyperspace, Michio Kaku offers the first book-length tour of the most exciting (and perhaps most bizarre) work in modern physics. <p><p>The theory of hyperspace (or higher dimensional space)—and its newest wrinkle, superstring theory—stand at the center of this revolution, with adherents in every major research laboratory in the world. Beginning where Hawking's Brief History of Time left off, Kaku paints a vivid portrayal of the breakthroughs now rocking the physics establishment. Why all the excitement? As the author points out, for over half a century, scientists have puzzled over why the basic forces of the cosmos—gravity, electromagnetism, and the strong and weak nuclear forces—require markedly different mathematical descriptions. But if we see these forces as vibrations in a higher dimensional space, their field equations suddenly fit together like pieces in a jigsaw puzzle, perfectly snug, in an elegant, astonishingly simple form. This may thus be our leading candidate for the Theory of Everything.

Hypogene Karst Regions and Caves of the World
by Alexander Klimchouk Arthur N. Palmer Jo De Waele Augusto S. Auler Philippe AudraThis book illustrates the diversity of hypogene speleogenetic processes and void-conduit patterns depending on variations of the geological environments by presenting regional and cave-specific case studies. The cases include both well-known and newly recognized hypogene karst regions and caves of the world. They all focus on geological, hydrogeological, geodynamical and evolutionary contexts of hypogene speleogenesis. The last decade has witnessed the boost in recognition of the possibility, global occurrence, and practical importance of hypogene karstification (speleogenesis), i. e. the development of solutional porosity and permeability by upwelling flow, independent of recharge from the overlying or immediately adjacent surface. Hypogene karst has been identified and documented in many regions where it was previously overlooked or misinterpreted. The book enriches the basis for generalization and categorization of hypogene karst and thus improves our ability to adequately model hypogene karstification and predict related porosity and permeability. It is a book which benefits every researcher, student, and practitioner dealing with karst.
Hyrdoacoustic Ocean Exploration: Theories and Experimental Application
by Iftikhar B. AbbasovThe only book that offers a comprehensive and fully up-to-date coverage of hydroacoustic ocean exploration, this work deals with the diagnostics of non-uniformities in a water medium using the hydroacoustic parametric antenna. The non-uniformities of the water medium in the study are of geometrically regular shape, i.e., the shape of a sphere, a cylinder, and a spheroid. An account is given of theoretical and experimental studies of wave processes that occur in the event of the scattering of non-linearly interacting acoustic waves at a sphere, a cylinder, and a spheroid. Scattering problems are formulated; solutions to the inhomogeneous wave equation are found in the first and second approximations using the successive approximations method. For the first time, high-frequency asymptotic expressions of acoustic pressure for all spectral components of the secondary field are obtained for the nonlinear scattering problem. The scattering diagrams are calculated and plotted, and then analyzed and compared. Results of experimental studies of the parametric acoustic antenna field scattering at solid steel spheres are presented. Experimental scattering diagrams both for the parametric antenna pump waves and for the secondary field waves including the difference frequency wave, the sum frequency wave, and the second harmonic wave are presented. 3D modeling of wave processes is also considered. A must have for researchers and specialists in nonlinear hydroacoustics and ocean acoustics; it also may be of use for postgraduates and students specializing in hydroacoustics and ocean exploration.

I Am Destroying The Land!: The Political Ecology Of Poverty And Environmental Destruction In Honduras
by Susan C StonichThis book is about interconnections-those among the historical, geographic, demographic, social, economic, and ecological aspects of development-as well as how Central Americans struggle with the interplay of increasing poverty and environmental degradation. Centering on the case of southern Honduras and expanding to include the Central American region, Susan Stonich's analysis employs an integrative approach that builds on a strong and varied methodological foundation to encompass both political economy and ecology. Stonich examines the systemic linkages among the dynamics of dominant development models and associated patterns of capitalist accumulation, regional demography, rural impoverishment, and environmental decline. By casting the discussion against the backdrop of southern Honduras, she presents a powerful historical record of how larger socio-political communities impact individuals and the natural environment and how, in turn, people respond. She charts the destiny of peasant groups within the dynamics of contemporary capitalism, recognizing that the fates of the peasantry and the natural environment are intimately linked. Stonich's study contributes to an improved understanding of the complex interrelationships between social processes and environmental degradation, offering a timely and pertinent comment on one of the most serious modern challenges
