Orbit

by John J. Nance

The year is 2009. For Kip Dawson, winning a passenger seat on American Space Adventure's spacecraft is a dream come true. One grand shot of insanity and he can return to earth fulfilled. But the thrill of the successful launch turns to terror when a micrometeorite penetrates the capsule, leaving the radios as dead as the pilot. Reality hits: Kip isn't going home. With nothing to do but wait for his doomed fate, Kip writes his epitaph on the ship's laptop computer, unaware that an audience of millions has discovered it and is tracking his every word on the Internet. As a massive struggle gets underway to rescue him, Kip has no idea that the world can hear his cries -- or that his heroism in the face of death may sabotage his best chance of survival.

Orbital Dynamics in the Gravitational Field of Small Bodies

by Yang Yu

This prizewinning PhD thesis presents a general discussion of the orbital motion close to solar system small bodies (SSSBs), which induce non-central asymmetric gravitational fields in their neighborhoods. It introduces the methods of qualitative theory in nonlinear dynamics to the study of local/global behaviors around SSSBs. Detailed mechanical models are employed throughout this dissertation, and specific numeric techniques are developed to compensate for the difficulties of directly analyzing. Applying this method, several target systems, like asteroid 216 Kleopatra, are explored in great detail, and the results prove to be both revealing and pervasive for a large group of SSSBs.

The Orbital Perspective: Lessons in Seeing the Big Picture from a Journey of 71 Million Miles

by Ron Garan

For astronaut Ron Garan, living on the International Space Station was a powerful, transformative experience—one that he believes holds the key to solving our problems here on Earth. On space walks and through windows, Garan was struck by the stunning beauty of the Earth from space but sobered by knowing how much needed to be done to help this troubled planet. And yet on the International Space Station, Garan, a former fighter pilot, was working work side by side with Russians, who only a few years before were “the enemy.” If fifteen nationalities could collaborate on one of the most ambitious, technologically complicated undertakings in history, surely we can apply that kind of cooperation and innovation toward creating a better world. That spirit is what Garan calls the “orbital perspective.”Garan vividly conveys what it was like learning to work with a diverse group of people in an environment only a handful of human beings have ever known. But more importantly, he describes how he and others are working to apply the orbital perspective here at home, embracing new partnerships and processes to promote peace and combat hunger, thirst, poverty, and environmental destruction. This book is a call to action for each of us to care for the most important space station of all: planet Earth. You don't need to be an astronaut to have the orbital perspective. Garan's message of elevated empathy is an inspiration to all who seek a better world.

Orbital Relative Motion and Terminal Rendezvous: Analytic and Numerical Methods for Spaceflight Guidance Applications (Space Technology Library #39)

by Jean Albert Kéchichian

This book provides a comprehensive analysis of time-fixed terminal rendezvous around the Earth using chemical propulsion.The book has two main objectives. The first is to derive the mathematics of relative motion in near-circular orbit when subjected to perturbations emanating from the oblateness of the Earth, third-body gravity, and atmospheric drag. The mathematics are suitable for quick trajectory prediction and the creation of computer codes and efficient software to solve impulsive maneuvers and fly rendezvous missions.The second objective of this book is to show how the relative motion theory is applied to the exact precision-integrated, long-duration, time-fixed terminal rendezvous problem around the oblate Earth for the general elliptic orbit case.The contents are both theoretical and applied, with long-lasting value for aerospace engineers, trajectory designers, professors of orbital mechanics, and students at the graduate level and above.

Orchestrating Human-Centered Design

by Guy Boy

The time has come to move into a more humanistic approach of technology and to understand where our world is moving to in the early twenty-first century. The design and development of our future products needs to be orchestrated, whether they be conceptual, technical or organizational. Orchestrating Human-Centered Design presents an Orchestra model that attempts to articulate technology, organizations and people. Human-centered design (HCD) should not be limited to local/short-term/linear engineering, but actively focus on global/long-term/non-linear design, and constantly identify emergent properties from the use of artifacts. Orchestrating Human-Centered Design results from incremental syntheses of courses the author has given at the Florida Institute of Technology in the HCD PhD program. It is focused on technological and philosophical concepts that high-level managers, technicians and all those interested in the design of artifacts should consider. Our growing software -intensive world imposes better knowledge on cognitive engineering, life-critical systems, complexity analysis, organizational design and management, modeling and simulation, and advanced interaction media, and this well-constructed and informative book provides a road map for this.

Orchestrating Inquiry Learning

by Mike Sharples Karen Littleton Eileen Scanlon

There is currently a rapidly growing interest in inquiry learning and an emerging consensus among researchers that, particularly when supported by technology, it can be a significant vehicle for developing higher order thinking skills. Inquiry learning methods also offer learners meaningful and productive approaches to the development of their knowledge of the world, yet such methods can present significant challenges for teachers and students. Orchestrating Inquiry Learning addresses the key challenge of how to resource and support processes of inquiry learning within and beyond the classroom. It argues that technological support, when coupled with appropriate design of activities and management of the learning environment, can enable inquiry learning experiences that are engaging, authentic and personally relevant. This edited collection of carefully integrated chapters brings together, for the first time; work on inquiry learning and orchestration of learning. Drawing upon a broad range of theoretical perspectives, this book examines: Orchestration of inquiry learning and instruction Trajectories of inquiry learning Designing for inquiry learning Scripting personal inquiry Collaborative and collective inquiry learning Assessment of inquiry learning Inquiry learning in formal and semi-formal educational contexts Orchestrating Inquiry Learning is essential reading for all those concerned with understanding and promoting effective inquiry learning. The book is aimed at an international audience of researchers, post-graduate students, and advanced undergraduates in education, educational technology and psychology. It will also be of interest to educational practitioners and policy makers, including teachers, educational advisors, teacher-students and their trainers.

The Orchid Cage: A Science Fiction Novel (Science and Fiction)

by Herbert W. Franke

This book is a new English translation of the classic science fiction story written in 1961 by Herbert W. Franke, widely held to be the most important German-language science-fiction writer. A dead city on a distant planet, two groups of people trying to explore it. Step by step, they penetrate the outer ring with its ultra-modern technology, the half-ruined medieval city center and finally the mysterious center. But is the eerie city really dead? Suddenly the factories start working again, the automatons intervene, and somewhere in the background there is still something hidden that could perhaps awaken. But is it people or machines? Herbert W. Franke leads the reader into an oppressively strange world; only after the startling resolution does it become clear what lies behind the adventures of the intruders - not a cosmic strangeness, but a threatening development that could affect humans in the same way. Franke's novel is thus a parable of the evolution of all humans in the age of technical communication ...

Orchids as Aphrodisiac, Medicine or Food

by Eng Soon Teoh

Did you know that Vanilla was formerly served as aphrodisiac by Cassanova and Madam Pompadour, and Elizabeth I loved its flavor? This is the first book that provides a complete worldwide coverage of orchids being employed as aphrodisiacs, medicine or charms and food. Opening with an in-depth historical account of orchids (orchis Greek testicle), the author describes how the Theory of Signatures influenced ancient herbalists to regard terrestrial orchid tubers as aphrodisiacs. Doctors and apothecaries promoted it during the Renaissance. Usage of orchids in Traditional Chinese Medicine, Indian Ayurvedic Medicine; by Tibetan yogins and Amchi healers for longevity pills, tonics and aphrodisiacs; by Africans to prepare 'health promoting' chikanda or as survival food when lost in the Australian bush are some highlights of the book. Early settlers in America and the East Indies often relied on native remedies and employment of orchids for such needs is described. Also covered are the search for medicinal compounds by scientists, attempts to prove the orchid's efficacy by experiment and the worry of conservationists.

Order and Fluctuations in Collective Dynamics of Swimming Bacteria: Experimental Exploration of Active Matter Physics (Springer Theses)

by Daiki Nishiguchi

This thesis focuses on experimental studies on collective motion using swimming bacteria as model active-matter systems. It offers comprehensive reviews of state-of-the-art theories and experiments on collective motion from the viewpoint of nonequilibrium statistical physics. The author presents his experimental studies on two major classes of collective motion that had been well studied theoretically. Firstly, swimming filamentous bacteria in a thin fluid layer are shown to exhibit true, long-range orientational order and anomalously strong giant density fluctuations, which are considered universal and landmark signatures of collective motion by many numerical and theoretical works but have never been observed in real systems. Secondly, chaotic bacterial turbulence in a three-dimensional dense suspension without any long-range order as described in the first half is demonstrated to be capable of achieving antiferromagnetic vortex order by imposing a small number of constraints with appropriate periodicity. The experimental results presented significantly advance our fundamental understanding of order and fluctuations in collective motion of motile elements and their future applications.

Ordering Colours in 18th and Early 19th Century Europe (International Archives of the History of Ideas Archives internationales d'histoire des idées #244)

by Tanja C. Kleinwächter Sarah Lowengard Friedrich Steinle

This book describes the international effort to give order to colours and thus facilitate communication about it, two topics deemed essential to a modernising world that were also recognizably complex. Expert essays will enhance readers' understanding of the struggle to coordinate nature with art at a time when approaches to both were undergoing rapid change. Ordering Colours shows how such seemingly trivial concerns as identifying the basic colours and disseminating appropriate colour diagrams had to meet philosophical, scientific and professional needs across Europe. Contributors detail the many schemes for colour systematization and their real-world applications; questions of concern to both academic- and manufacturing-focused investigators throughout the long 18th century. They bring together original research and new thinking about landmark early modern studies to address important developments as well as neglected historical contributions of European arts, sciences, and economies. This collection is an important addition to the libraries of all who are interested in public culture and manufacturing developments in the early modern period and is aimed at historians of art, technology, philosophy and physics.

Ordinary and Fractional Approximation by Non-additive Integrals: Choquet, Shilkret and Sugeno Integral Approximators (Studies in Systems, Decision and Control #190)

by George A. Anastassiou

Ordinary and fractional approximations by non-additive integrals, especially by integral approximators of Choquet, Silkret and Sugeno types, are a new trend in approximation theory. These integrals are only subadditive and only the first two are positive linear, and they produce very fast and flexible approximations based on limited data. The author presents both the univariate and multivariate cases. The involved set functions are much weaker forms of the Lebesgue measure and they were conceived to fulfill the needs of economic theory and other applied sciences. The approaches presented here are original, and all chapters are self-contained and can be read independently. Moreover, the book’s findings are sure to find application in many areas of pure and applied mathematics, especially in approximation theory, numerical analysis and mathematical economics (both ordinary and fractional). Accordingly, it offers a unique resource for researchers, graduate students, and for coursework in the above-mentioned fields, and belongs in all science and engineering libraries.

Ordinary Geniuses: How Two Mavericks Shaped Modern Science

by Gino Segre

A biography of two maverick scientists whose intellectual wanderlust kick-started modern genomics and cosmology. <P><P> Max Delbruck and George Gamow, the so-called ordinary geniuses of Segre's third book, were not as famous or as decorated as some of their colleagues in midtwentieth-century physics, yet these two friends had a profound influence on how we now see the world, both on its largest scale (the universe) and its smallest (genetic code). Their maverick approach to research resulted in truly pioneering science. Wherever these men ventured, they were catalysts for great discoveries. Here Segre honors them in his typically inviting and elegant style and shows readers how they were far from "ordinary". While portraying their personal lives Segre, a scientist himself, gives readers an inside look at how science is done--collaboration, competition, the influence of politics, the role of intuition and luck, and the sense of wonder and curiosity that fuels these extraordinary minds. Ordinary Geniuses will appeal to the readers of Simon Singh, Amir Aczel, and other writers exploring the history of scientific ideas and the people behind them.

Oregon Wildland Firefighting: A History

by Sean Davis

Over the past century, some of the world's largest wildland fires have occurred in Oregon. Accidentally set by a disgruntled cook on an English ship, the Great Fire of 1845 displaced multiple tribes and boiled wildlife alive in the Columbia River. The Tillamook Burn started up every 6 years from 1933 to 1951 and incited one of the largest reseeding efforts in the world with 72 million seedlings planted. The Long Draw Fire of 2012, the state's largest in more than 150 years, started as a small spark and raged into an ocean of flames thousands of acres wide in a matter of hours. Veteran wildland firefighter Sean Davis shares harrowing firsthand accounts that illustrate what it takes to battle an inferno.

Oregon's Covered Bridges

by Bill Cockrell

Rugged individuals armed with hand tools, sweat, and ambition began building covered bridges in Oregon during the mid-1850s. These bridge builders often camped out at remote sites, living off the land or contracting with local farmers for food. Early owners of covered bridges financed construction by charging tolls--3¢ for a sheep, 5¢ for a horse and rider, and 10¢ for a team of horses and wagon. In the early 20th century, the state provided standard bridge and truss designs to each county, and most of the resulting structures incorporated the Howe truss. With the abundance of Douglas fir and the shortage of steel during the world wars, the construction of wooden covered bridges continued well into the 1950s, mainly in the Willamette Valley. During the 1920s, Oregon boasted more than 350 covered bridges.
