An Analytical Mechanics Framework for Flow-Oscillator Modeling of Vortex-Induced Bluff-Body Oscillations (Solid Mechanics and Its Applications #260)

by Haym Benaroya Sohrob Mottaghi Rene Gabbai

This self-contained book provides an introduction to the flow-oscillator modeling of vortex-induced bluff-body oscillations. One of the great challenges in engineering science also happens to be one of engineering design – the modeling, analysis and design of vibrating structures driven by fluid motion. The literature on fluid–structure interaction is vast, and it can be said to comprise a large fraction of all papers published in the mechanical sciences. This book focuses on the vortex-induced oscillations of an immersed body, since, although the importance of the subject has long been known, it is only during the past fifty years that there have been concerted efforts to analytically model the general behavior of the coupling between vortex shedding and structural oscillations. At the same time, experimentalists have been gathering data on such interactions in order to help define the various regimes of behavior. This data is critical to our understanding and to those who develop analytical models, as can be seen in this book. The fundamental bases for the modeling developed in this book are the variational principles of analytical dynamics, in particular Hamilton’s principle and Jourdain’s principle, considered great intellectual achievements on par with Newton’s laws of motion. Variational principles have been applied in numerous disciplines, including dynamics, optics and quantum mechanics. Here, we apply variational principles to the development of a framework for the modeling of flow-oscillator models of vortex-induced oscillations.

An Anthology of Theories and Models of Design: Philosophy, Approaches and Empirical Explorations

by Amaresh Chakrabarti Lucienne T. M. Blessing

While investigations into both theories and models has remained a major strand of engineering design research, current literature sorely lacks a reference book that provides a comprehensive and up-to-date anthology of theories and models, and their philosophical and empirical underpinnings; An Anthology of Theories and Models of Design fills this gap. The text collects the expert views of an international authorship, covering: #65533; significant theories in engineering design, including CK theory, domain theory, and the theory of technical systems; #65533; current models of design, from a function behavior structure model to an integrated model; #65533; important empirical research findings from studies into design; and #65533; philosophical underpinnings of design itself. For educators and researchers in engineering design, An Anthology of Theories and Models of Design gives access to in-depth coverage of theoretical and empirical developments in this area; for practitioners, the book will provide exposure to theoretical and empirical foundations to methods and tools that are currently practiced as well as those in the process of development.

An Anthropogenic Table of Elements: Experiments in the Fundamental (Technoscience and Society)

by Timothy Neale Courtney Addison Thao Phan

An Anthropogenic Table of Elements provides a contemporary rethinking of Dmitri Mendeleev’s periodic table of elements, bringing together "elemental" stories to reflect on everyday life in the Anthropocene. Concise and engaging, this book provides stories of scale, toxicity, and temporality that extrapolate on ideas surrounding ethics, politics, and materiality that are fundamental to this contemporary moment. Examining elemental objects and forces, including carbon, mould, cheese, ice, and viruses, the contributors question what elemental forms are still waiting to emerge and what political possibilities of justice and environmental reparation they might usher into the world. Bringing together anthropologists, historians, and media studies scholars, this book tests a range of possible ways to tabulate and narrate the elemental as a way to bring into view fresh discussion on material constitutions and, thereby, new ethical stances, responsibilities, and power relations. In doing so, An Anthropogenic Table of Elements demonstrates through elementality that even the smallest and humblest stories are capable of powerful effects and vast journeys across time and space.

An Anthropology of Robots and AI: Annihilation Anxiety and Machines (Routledge Studies in Anthropology #20)

by Kathleen Richardson

This book explores the making of robots in labs at the Massachusetts Institute of Technology (MIT). It examines the cultural ideas that go into the making of robots, and the role of fiction in co-constructing the technological practices of the robotic scientists. The book engages with debates in anthropological theorizing regarding the way that robots are reimagined as intelligent, autonomous and social and weaved into lived social realities. Richardson charts the move away from the “worker” robot of the 1920s to the “social” one of the 2000s, as robots are reimagined as companions, friends and therapeutic agents.

An Anthropology of the Machine: Tokyo's Commuter Train Network

by Michael Fisch

“An astute account of [Tokyo’s] commuter train network . . . and an intellectually stimulating invitation to rethink the interaction between humans and machines.” —Japan ForumWith its infamously packed cars and disciplined commuters, Tokyo’s commuter train network is one of the most complex technical infrastructures on Earth. In An Anthropology of the Machine, Michael Fisch provides a nuanced perspective on how Tokyo’s commuter train network embodies the lived realities of technology in our modern world. Drawing on his fine-grained knowledge of transportation, work, and everyday life in Tokyo, Fisch shows how fitting into a system that operates on the extreme edge of sustainability can take a physical and emotional toll on a community while also creating a collective way of life—one with unique limitations and possibilities.An Anthropology of the Machine is a creative ethnographic study of the culture, history, and experience of commuting in Tokyo. At the same time, it is a theoretically ambitious attempt to think through our very relationship with technology and our possible ecological futures. Fisch provides an unblinking glimpse into what it might be like to inhabit a future in which more and more of our infrastructure—and the planet itself—will have to operate beyond capacity to accommodate our ever-growing population.“Not a ‘rage against the machine’ but an urge to find new ways of coexisting with technology.” —Contemporary Japan“An extraordinary study.” —Ethnos“A fascinating in-depth account of the innovations, inventions, sacrifices, and creativity required to ensure Tokyo’s millions of commuters keep rolling. It also provides much food for thought as our transportation systems become increasingly reliant on automated technology.” —Pacific Affairs

An Assessment Of The Sbir Program At The National Science Foundation

by National Research Council of the National Academies

The Small Business Innovation Research (SBIR) program is one of the largest examples of U.S. public-private partnerships. Founded in 1982, SBIR was designed to encourage small business to develop new processes and products and to provide quality research in support of the many missions of the U.S. government, including health, energy, the environment, and national defense. In response to a request from the U.S. Congress, the National Research Council assessed SBIR as administered by the five federal agencies that together make up 96 percent of program expenditures. This book, one of six in the series, reports on the SBIR program at the National Science Foundation. The study finds that the SBIR program is sound in concept and effective in practice, but that it can also be improved. Currently, the program is delivering results that meet most of the congressional objectives, including stimulating technological innovation, increasing private-sector commercialization of innovations, using small businesses to meet federal research and development needs, and fostering participation by minority and disadvantaged persons. The book suggests ways in which the program can improve operations, continue to increase private-sector commercialization, and improve participation by women and minorities.

An Assessment of Mine Legacies and How to Prevent Them: A Case Study from Latin America (SpringerBriefs in Environmental Science)

by Vladimir Pacheco Cueva

This book seeks to enrich the growing literature on mine legacies by examining a case study of a small abandoned mine in Latin America. Using a combination of Rapid Rural Appraisal and secondary source analysis, this study assessed some of the most damaging legacies of the San Sebastian mine in eastern El Salvador, compared the country's mine closure legislation against world's best practice standards and provided strategies for awareness, prevention and remediation. The most damaging legacy to the environment is that of Acid Mine Drainage (AMD) contamination of the local river. The impact of AMD is felt well beyond the mining district and the costs of prevention and remediation were found to be significant. Apart from environmental legacies, the mine also left a number of socio-economic legacies including: limited access to non-polluted water that results in San Sebastian residents devoting a high proportion of their income in obtaining water, lost opportunities due to the cessation of mining, uncertain land tenure situation and increasing growth of ASGM activities that exacerbate already existing environmental pollution due to use of mercury. The study also found that the state's capacity to ensure compliance with the law is very weak and that in many important respects the country's current legal framework does not meet world's best practice when it comes to mine closure requirements. The findings are important because they demonstrate that the lack of closure planning can lead to private operators socializing the costs of pollution. The study also shows that the lack of state capacity may result in extractive projects becoming socio-economic liabilities in the long term.

An Assessment of Non-Lethal Weapons Science and Technology

by Technology Committee for an Assessment of Non-Lethal Weapons Science

Non-lethal weapons (NLWs) are designed to minimize fatalities and other undesired collateral damage when used. Events of the last few years including the attack on the USS Cole have raised ideas about the role NLWs can play in enhancing support to naval forces. In particular to what extent and in what areas should Department of the Navy (DoN) -sponsored science and technology (S&T) provide a research base for developing NLW capabilities? To assist with this question and to evaluate the current NLWs program, the Joint Non-Lethal Weapons Directorate (JNLWD) and the Office of Naval Research (ONR) requested the National Research Council perform an assessment of NLWs science and technology. The report presents the results of that assessment. It discusses promising NLW S&T areas, development accomplishments and concerns about NLW, and series of recommendations about future NLW development and application.
