Diversity and Non-integer Differentiation for System Dynamics
Based on a structured approach to diversity, notably inspired by various forms of diversity of natural origins, Diversity and Non-integer Derivation Applied to System Dynamics provides a study framework to the introduction of the non-integer derivative as a modeling tool. Modeling tools that highlight unsuspected dynamical performances (notably damping performances) in an «integer» approach of mechanics and automation are also included. Written to enable a two-tier reading, this is an essential resource for scientists, researchers, and industrial engineers interested in this subject area. Table of Contents: 1. From Diversity to Unexpected Dynamic Performance. 2. The Robustness of Damping. 3. Fractional Differentiation and its Memory. 4. CRONE Suspension Idea. 5. CRONE Control Idea
Erosion in Geomechanics Applied to Dams and Levees
Erosion is the most common cause of failures at earth-dams, dikes and levees, whether through overtopping and overflowing, or internal erosion and piping. This book is dedicated to the phenomenon of internal erosion and piping. It is not intended to be exhaustive on the subject, but brings together some of the latest international research and advances. Emphasis is placed on physical processes, how they can be studied in the laboratory, and how test results can be applied to levees and dams. The results from several research projects in Australia, France, the Netherlands and the United States are covered by the authors. Our aim has been to share our most recent findings with students, researchers and practitioners. Understanding the failure of an earth-dam or a levee by erosion in a unified framework, whether internal erosion or surface erosion, requires continuous research in this field. We hope that the reader will gain knowledge from this book that leads to further progress in the challenging field of the safety of levees and dams. Contents 1. State of The Art on the Likelihood of Internal Erosion of Dams and Levees by Means of Testing, Robin Fell and Jean-Jacques Fry. 2. Contact Erosion, Pierre Philippe, Rémi Beguin and Yves-Henri Faure. 3. Backward Erosion Piping, Vera Van Beek, Adam Bezuijen and Hans Sellmeijer. 4. Concentrated Leak Erosion, Stéphane Bonelli, Robin Fell and Nadia Benahmed. 5. Relationship between the Erosion Properties of Soils and Other Parameters, Robin Fell, Gregory Hanson, Gontran Herrier, Didier Marot and Tony Wahl. About the Authors Stéphane Bonelli is a Research Professor at Irstea (French Environmental Sciences and Technologies Research Institute) in Aix-en-Provence, France. He has over 20 years of teaching and research experience, and has been a member of the ICOLD (International Commission on Large Dams) European Working Group on Internal Erosion since 2005. He has participated in 19 large dam reviews in France (visual inspection, monitoring data analysis and numerical modeling). His current activities include research, teaching and consultancy, focusing on soil erosion and the processes of levee breach.
Rotating Thermal Flows in Natural and Industrial Processes
Rotating Thermal Flows in Natural and Industrial Processes provides the reader with a systematic description of the different types of thermal convection and flow instabilities in rotating systems, as present in materials, crystal growth, thermal engineering, meteorology, oceanography, geophysics and astrophysics. It expressly shows how the isomorphism between small and large scale phenomena becomes beneficial to the definition and ensuing development of an integrated comprehensive framework. This allows the reader to understand and assimilate the underlying, quintessential mechanisms without requiring familiarity with specific literature on the subject. Topics treated in the first part of the book include: • Thermogravitational convection in rotating fluids (from laminar to turbulent states); • Stably stratified and unstratified shear flows; • Barotropic and baroclinic instabilities; • Rossby waves and Centrifugally-driven convection; • Potential Vorticity, Quasi-Geostrophic Theory and related theorems; • The dynamics of interacting vortices, interacting waves and mixed (hybrid) vortex-wave states; • Geostrophic Turbulence and planetary patterns. The second part is entirely devoted to phenomena of practical interest, i.e. subjects relevant to the realms of industry and technology, among them: • Surface-tension-driven convection in rotating fluids; • Differential-rotation-driven (forced) flows; • Crystal Growth from the melt of oxide or semiconductor materials; • Directional solidification; • Rotating Machinery; • Flow control by Rotating magnetic fields; • Angular Vibrations and Rocking motions; Covering a truly prodigious range of scales, from atmospheric and oceanic processes and fluid motion in “other solar-system bodies”, to convection in its myriad manifestations in a variety of applications of technological relevance, this unifying text is an ideal reference for physicists and engineers, as well as an important resource for advanced students taking courses on the physics of fluids, fluid mechanics, thermal, mechanical and materials engineering, environmental phenomena, meteorology and geophysics.

Free Space Optical Networks for Ultra-Broad Band Services
This book provides a comprehensive description of an optical communications technology known as free space optical—a next-generation communications network that uses optical signals through the atmosphere instead of fiber, RF, or microwaves. This technology potentially offers more complex ultrabandwidth communication services simultaneously to multiple users and in a very short time, compared to fiber optic technology. This text presents established and new advancements drawn from the latest research and development in components, networking, operation, and practices. This book describes the FSO network concepts in simple language. It provides comprehensive coverage in an easy-to-understand, progressive style that starts from the physics of the atmosphere and how it affects optical communications; continues with the design of a network node; and concludes with fiberless network applications from point-to-point to mesh topology. Important areas discussed include: Propagation of light in the atmosphere and phenomena that affect light propagation FSO transceiver design Point-to-point FSO systems Ring FSO systems Mesh-FSO systems and integrating the Mesh-FSO with the public network WDM Mesh-FSO FSO network security FSO-specific applications To meet the needs of both academia and industry, key mathematical formulas are presented along with descriptions, while extensive mathematical analyses are minimized or avoided. Free Space Optical Networks for Ultra-Broad Band Services serves as an ideal text for network communication professionals who enter the free space optical communication field, graduate students majoring in optical communications, optical communication engineers, researchers, managers, and consultants.
Die Invasion der Waschbären. und andere Expeditionen in die wilde Natur
Bald leben mehr als eine Million (!) Waschbaren in unseren Waldern und nicht nur da ? sie kommen uns auch in den Stadten >besuchen<. Die putzigen Kerlchen konnen nichts dafur, denn wir sind an ihrer Verbreitung Schuld, da wir das okologische Gleichgewicht der Natur gestort haben. Doch was genau ist eigentlich Okologie jenseits von Okostrom und Okolabel? Hightech-Ameisen, hochintelligente Krahen und der Urzeit-Ginkgo Alles hangt mit allem zusammen: Gerat ein okologisches Teilsystem aus dem Gleichgewicht, lost das oft eine Kettenreaktion aus. In dem Teil Zusammen leben fragt Michael Gro? u. a., ob Schutzgebiete wirklich die bedrohten Arten schutzen, erzahlt uber die Wanderschaft von Pflanzenschadlingen, die sich durch weltweite Handelsnetze auch global verbreiten, oder stellt einen Uberlebenden der Dinosaurierzeit vor: den Ginkgo. Warum uberlebte er damals das Massensterben der Arten? Kohlendioxidschwaden, Vibrationen, Magnetismus, Pedometer und noch vieles mehr: All das besitzt z. B. ein sehr kleines Lebewesen ? die Ameise. Sie findet mit dieser >Ausstattung< sogar in der Wuste wieder zu ihrem Nest zuruck. Im Teil Aktiv leben stellt uns Gro? diese kleinen tierischen Wunderwerke vor, berichtet aber auch von den hochintelligenten Krahen oder erzahlt, wie das Krokodil seine Zahne bekam. Im Abschnitt Weiter leben gibt er einen Ausblick auf die unmittelbare Zukunft des Lebens auf der Erde, die immer starker von menschlichen Aktivitaten gepragt wird: das Zeitalter des >Anthropozan< ist angebrochen!

Who Owns You? Science, Innovation, and the Gene Patent Wars
The 2nd Edition of Who Owns You, David Koepsell’s widely acclaimed exploration of the philosophical and legal problems of patenting human genes, is updated to reflect the most recent changes to the cultural and legal climate relating to the practice of gene patenting. Lays bare the theoretical assumptions that underpin the injustice of patents on unmodified genes Makes a unique argument for a commons-by-necessity, explaining how parts of the universe are simply not susceptible to monopoly claims Represents the only work that attempts to first define the nature of the genetic objects involved before any ethical conclusions are reached Provides the most comprehensive accounting of the various lawsuits, legislative changes, and the public debate surrounding AMP v. Myriad, the most significant case regarding gene patents
