Holistic Simulation of Geotechnical Installation Processes
by Theodoros TriantafyllidisThis book examines in detail the entire process involved in implementing geotechnical projects, from a well-defined initial stress and deformation state, to the completion of the installation process. The individual chapters provide the fundamental knowledge needed to effectively improve soil-structure interaction models. Further, they present the results of theoretical fundamental research on suitable constitutive models, contact formulations, and efficient numerical implementations and algorithms. Applications of fundamental research on boundary value problems are also considered in order to improve the implementation of the theoretical models developed. Subsequent chapters highlight parametric studies of the respective geotechnical installation process, as well as elementary and large-scale model tests under well-defined conditions, in order to identify the most essential parameters for optimizing the process. The book provides suitable methods for simulating boundary value problems in connection with geotechnical installation processes, offering reliable predictions for the deformation behavior of structures in static contexts or dynamic interaction with the soil.

Holistisches Chancen-Risiken-Management von Grossprojekten: Unbekanntes erkennen und handeln
by Konrad BergmeisterExtreme Ereignisse sind in unserem Denken meist weit weg entfernt. Treten sie trotzdem ein, treffen sie uns oft unerwartet. Wenn Ereignisse mit schweren Folgen für die Umwelt und den Menschen einzeln auftreten, werden sie von den meisten Menschen als extrem empfunden. Eine Vielzahl von kleineren Ereignissen über einen längeren Zeitraum, deren Wirkung in Summe ähnlich groß ist, kümmern hingegen kaum jemanden. Gerade bei großen Bauprojekten verursacht das Eintreten von nicht erwarteten, extremen Ereignissen wie Naturgefahren, der Einsturz einer Brücke oder der Brand in einem Tunnel oft eine auch öffentlich wahrgenommene Schockwirkung. Aber auch die Überschreitung von Kosten und Bauzeiten, bedingt durch unbekannte Risiken, verursachen Ängste und Schuldzuweisungen.Das Buch zeigt einen möglichen Weg auf, wie solchen unbekannten Risiken aber auch Chancen begegnet werden kann. Basierend auf wissenschaftlichen Grundlagen und umfangreichen prak-tischen Erfahrungen wird ein strukturiertes holistisches Chancen-Risiken-Management für Großprojekte erläutert. Auch auf die Corona-Thematik wird aus Sicht des Chancen-Risiken- Managements eingegangen.
Hollow Core Optical Fibre Based Gas Discharge Laser Systems (Springer Theses)
by Adrian LoveThe research in this book represents the culmination of a drive to build the first discharge gas laser unencumbered by the effects of diffraction. This breakthrough has been achieved through careful implementation of a discharge within a hollow-core optical fibre, and by developing measurement and analysis techniques to demonstrate laser action in an experimental optical cavity. Gas lasers were amongst the earliest laser types to be demonstrated and commercialised, but it was recognised that noble gas lasers were limited by the minimum bore diameter of the laser tube, which is set by diffraction. The advent, in 2011, of hollow optical fibres with optical and physical properties suitable for gas discharge lasers opened up the opportunity to break this diffraction limit. Using a mixture of helium and xenon gas, lasing in the mid-infrared range was achieved using a 100µm core flexible hollow optical fibre which, at 1m long, is several hundred times the diffraction-limited Rayleigh length.

Hollywood Lighting from the Silent Era to Film Noir (Film and Culture Series)
by Patrick KeatingLighting performs essential functions in Hollywood films, enhancing the glamour, clarifying the action, and intensifying the mood. Examining every facet of this understated art form, from the glowing backlights of the silent period to the shaded alleys of film noir, Patrick Keating affirms the role of Hollywood lighting as a distinct, compositional force.Closely analyzing Girl Shy (1924), Anna Karenina (1935), Only Angels Have Wings (1939), and T-Men (1947), along with other brilliant classics, Keating describes the unique problems posed by these films and the innovative ways cinematographers handled the challenge. Once dismissed as crank-turning laborers, these early cinematographers became skillful professional artists by carefully balancing the competing demands of story, studio, and star. Enhanced by more than one hundred illustrations, this volume counters the notion that style took a backseat to storytelling in Hollywood film, proving that the lighting practices of the studio era were anything but neutral, uniform, and invisible. Cinematographers were masters of multifunctionality and negotiation, honing their craft to achieve not only realistic fantasy but also pictorial artistry.
Hollywood Science: Movies, Science, and the End of the World (Acs Symposium Ser. #1139)
by Sidney PerkowitzWhether depicting humans battling aliens or a brave geologist saving lives as a volcano erupts, science-fiction films are an exciting visual and sensuous introduction to the workings of science and technology. These films explore a range of complex topics in vivid and accessible ways, from space travel and laser technology to genetic engineering, global warming, and the consequences of nuclear weaponry. Though actual scientific lab work might not be as exciting, science fiction is an engaging yet powerful way for a wide audience to explore some of the most pressing issues and ideas of our time.In this book, a scientist and dedicated film enthusiast discusses the portrayal of science in more than one hundred films, including science fiction, scientific biographies, and documentaries. Beginning with early films like Voyage to the Moon and Metropolis and concluding with more recent offerings like The Matrix, War of the Worlds, A Beautiful Mind, and An Inconvenient Truth, Sidney Perkowitz questions how much faith we can put into Hollywood's depiction of scientists and their work; how accurately these films capture scientific fact and theory; whether cataclysms like our collision with a comet can actually happen; and to what extent these films influence public opinion about science and the future. Movies, especially science-fiction films, temporarily remove viewers from the world as they know it and show them the world as it might be, providing special perspective on human nature and society. Yet "Hollywood science" can be erroneous, distorting fact for dramatic effect and stereotyping scientists as remote and nerdy, evil, or noble, doing little to improve the relationship between science and society. Bringing together history, scientific theory, and humorous observation, Hollywood Science features dozens of film stills and a list of the all-time best and worst science-fiction movies. Just as this genre appeals to all types of viewers, this book will resonate with anyone who has been inspired by science-fiction films and would like to learn how fantasy compares to fact.

Holographic Interferometry: A Mach–Zehnder Approach
by Gregory R. TokerTransparent in the visible range, phase objects can be studied in the optical range using holographic interferometry. Typically, the holograms are recorded on high-resolving-power holographic photo materials, but a lower spatial resolution is sufficient for successful research in many scientific applications. Holographic Interferometry: A Mach–Zehnder Approach offers practical guidance to research scientists and engineers using Mach–Zehnder holographic interferometry methods to study phase objects in the laboratory. The Mach–Zehnder approach allows the use of standard photographic film and electronic CCD/CMOS sensors with low resolving power, making it a simpler and more affordable option for testing many types of phase objects.This book demonstrates how to use standard photographic film for the optical recording and reconstruction of Mach–Zehnder holograms. It also illustrates techniques for using CCD/CMOS cameras to digitally record Mach–Zehnder holograms/interferograms of transparent objects. Bringing together original research and information scattered throughout existing literature, this book focuses on the holographic reference beam and shearing interferometry methods. In particular, it looks at how these methods and optical schemes can be directly applied to testing aerodynamic flows, as well as to plasmas, shocks, and waves in noncoherent laser–matter interactions. Numerous reconstructed and classic interferograms, deflectograms, and Schlierengrams illustrate the material, helping readers develop and design their own optimal optical scheme and choose applicable details to apply the approach. Describing methods in a mathematically simple and accessible way, this book is also suitable for graduate students in the fields of aerospace engineering and optics, as well as those in laser, thermal, and plasma physics.

Holomorphic Foliations with Singularities: Key Concepts and Modern Results (Latin American Mathematics Series)
by Bruno ScárduaThis concise textbook gathers together key concepts and modern results on the theory of holomorphic foliations with singularities, offering a compelling vision on how the notion of foliation, usually linked to real functions and manifolds, can have an important role in the holomorphic world, as shown by modern results from mathematicians as H. Cartan, K. Oka, T. Nishino, and M. Suzuki.The text starts with a gentle presentation of the classical notion of foliations, advancing to holomorphic foliations and then holomorphic foliations with singularities. The theory behind reduction of singularities is described in detail, as well the cases for dynamics of a local diffeomorphism and foliations on complex projective spaces. A final chapter brings recent questions in the field, as holomorphic flows on Stein spaces and transversely homogeneous holomorphic foliations, along with a list of open questions for further study and research. Selected exercises at the end of each chapter help the reader to grasp the theory.Graduate students in Mathematics with a special interest in the theory of foliations will especially benefit from this book, which can be used as supplementary reading in Singularity Theory courses, and as a resource for independent study on this vibrant field of research.

Holy Shit: Managing Manure to Save Mankind
by Gene LogsdonIn his insightful book, Holy Shit: Managing Manure to Save Mankind, contrary farmer Gene Logsdon provides the inside story of manure — our greatest, yet most misunderstood, natural resource.He begins by lamenting a modern society that not only throws away both animal and human manure, worth billions of dollars in fertilizer value, but that spends a staggering amount of money to do so. This wastefulness makes even less sense as the supply of mined or chemically synthesized fertilizers dwindles and their cost skyrockets. In fact, he argues, if we do not learn how to turn our manures into fertilizer to keep food production in line with the increasing population, our civilization, like so many that went before it, will inevitably decline.With his trademark humor, years of experience writing about both farming and waste management, and uncanny eye for the small but important details, Logsdon artfully describes how to manage farm manure, pet manure and human manure to make fertilizer and humus. He covers the field, so to speak, discussing topics like:How to select the right pitchfork for the job and use it correctlyHow to operate a small manure spreaderHow to build a barn manure pack with farm animal manureHow to compost cat and dog wasteHow to recycle toilet water for irrigation purposes, andHow to get rid ourselves of our irrational paranoia about feces and urine.Gene Logsdon does not mince words. This fresh, fascinating and entertaining look at an earthy, but absolutely crucial subject, is a small gem destined to become a classic of our agricultural literature."Gene Logsdon, in his naughty and inimical style, has captured the essence of soil building, pathogen control, food ecology, and farm economics by explaining the elegantly simple symbiosis between manure and carbon. What a great addition to the eco-food and farming movement. . . Read and heed."—Joel Salatin, Author of You Can Farm and The Sheer Ecstasy of Being a Lunatic Farmer

Holzschutz in der Praxis: Schnelleinstieg für Architekten und Bauingenieure (essentials)
by Bernhard KopffBernhard Kopff zeigt, was beim Holzschutz in der Planung, Ausführung oder Sanierung eines Bauwerks oder beim Innenausbau von Gebäuden zu beachten ist. Damit Bauwerke aus Holz langlebig sind, müssen wichtige Planungsgrundsätze beachtet werden. Der Autor zeigt anhand konkreter Planungsbeispiele, wie alte und bewährte Prinzipien umgesetzt werden können. Sie entwickeln sich aus dem Stoffkreislauf, der Holz zu einem ökologisch unbedenklichen und trotzdem sehr beständigen Baustoff macht. Die Schadmechanismen werden kurz und anschaulich dargestellt, sodass wirksamer Holzschutz in der Planung erarbeitet und bei der Ausführung berücksichtigt werden kann. Es werden aber auch die Grenzen des dauerhaften Bauens mit Holz dargestellt. Da Holz schadlos in den natürlichen Kreislauf eingeht, kann es ebensofür temporäre Lösungen eingesetzt werden. Dem Leser werden die Zusammenhänge sehr anwendungsnah vermittelt, sodass er das Wissen in seiner täglichen Arbeit anwenden kann.Der Autor Dipl.-Ing. (FH) Bernhard Kopff ist Architekt und Bausachverständiger und arbeitet als Sachverständiger für Holz als Bau-und Werkstoff, Holzschutz und Schäden an Gebäuden.
