This book was released on 2004-04-05 with total page 159 pages. Available in PDF, EPUB and Kindle. Book excerpt: Deep-diving manned submersibles, such as Alvin, which gained worldwide fame when researchers used it to reach the wreck of the Titanic, have helped advance deep-ocean science. But many scholars in this field have noted that the number and capabilities of today's underwater vehicles no longer meet current scientific demands. At the same time, the relative value of manned and unmanned vehicles is often disputed. The report finds that new submersibles-both manned and unmanned-that are more capable than those in the current fleet are needed and would be of great value to the advancement of ocean research.
Download or read book Multidisciplinary Design Optimization and Its Application in Deep Manned Submersible Design written by Binbin Pan and published by Springer Nature. This book was released on 2020-08-28 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book investigates Reliability-based Multidisciplinary Design Optimization (RBMDO) theory and its application in the design of deep manned submersibles (DMSs). Multidisciplinary Design Optimization (MDO) is an effective design method for large engineering systems like aircraft, warships, and satellites, which require designers and engineers from various disciplines to cooperate with each other. MDO can be used to handle the conflicts that arise between these disciplines, and focuses on the optimal design of the system as a whole. However, it can also push designs to the brink of failure. In order to keep the system balanced, Reliability-based Design (RBD) must be incorporated into MDO. Consequently, new algorithms and methods have to be developed for RBMDO theory. This book provides an essential overview of MDO, RBD, and RBMDO and subsequently introduces key algorithms and methods by means of case analyses. In closing, it introduces readers to the design of DMSs and applies RBMDO methods to the design of the manned hull and the general concept design. The book is intended for all students and researchers who are interested in system design theory, and for engineers working on large, complex engineering systems.

Download or read book Deep Seabed Mining in the Indian Ocean Economic and Strategic Dimensions written by Commander (Dr) Nitin Agarwala and published by National Maritime Foundation. This book was released on 2019-11-01 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The book looks at the need of minerals for humanity, how and what the oceans offer as minerals in general, the technological developments achieved and the insight into future technologies and designs in this field before finally focusing on the mineral wealth of the Indian Ocean. It eventually poses some tough questions that need answers if deep seabed mining is to become a success in the future. In addition, it discusses the efforts of the key players in this field operating in the Indian ocean that has rejuvenated the deep seabed mining both economically and strategically. Since, commercial profitability of marine minerals occurs only if the demand is greater than the supply, at times, the decision gets governed by strategic reasoning. Hence, the book aims to give an idea of the driving forces that guide such decision-making and the development of deep seabed mining.

Download or read book Atlantic Salmon in Maine written by National Research Council and published by National Academies Press. This book was released on 2004-10-07 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: Because of the pervasive and substantial decline of Atlantic salmon populations in Maine over the past 150 years, and because they are close to extinction, a comprehensive statewide action should be taken now to ensure their survival. The populations of Atlantic salmon have declined drastically, from an estimated half million adult salmon returning to U.S. rivers each year in the early 1800s to perhaps as few as 1,000 in 2001. The report recommends implementing a formalized decision-making approach to establish priorities, evaluate options and coordinate plans for conserving and restoring the salmon.
Download or read book Final Comments on the Science Plan for the North Pacific Research Board written by National Research Council and published by National Academies Press. This book was released on 2005-02-22 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: The North Pacific Research Board (NPRB) was established by Congress in 1997 to recommend marine research activities to the Secretary of Commerce on or relating to the fisheries or marine ecosystem in the North Pacific Ocean, Bering Sea, Arctic Ocean, and related bodies of water. NPRB called on the National Academies to develop a comprehensive long range science plan pertaining to its research activities. This assistance has been provided in two phases. In phase one, beginning in early 2003, a National Academies committee worked to understand the purpose of the NPRB, gather information to help identify research needs, and provide advice on the components of a sound science plan. The committee's assessment is contained in a report released in early 2004, Elements of a Science Plan for the North Pacific Research Board. With this guidance as a tool, the NPRB staff, Science Panel, and Advisory Panel worked together to write a draft science plan to steer the program in the coming decade. During the second phase, the same committee reviewed the NPRB's draft science plan and provided final feedback to the NPRB. It is a focused review, generally following the organization of the NPRB document. This report is intended primarily as a direct communication from the committee to those planning the NPRB's programs, to help them improve the science plan and ensure successful implementation.
Download or read book Ocean Outpost written by Erik Seedhouse and published by Springer Science & Business Media. This book was released on 2010-09-29 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the greatest scientific and technological achievements of the 21st century will be to cast a light on the eternal darkness of the deep ocean and this book identifies the key determinants of life or death in its extreme environment. Dr. Erik Seedhouse examines how individuals survive free dives to 200m, how humans adapt to breathing exotic gas mixes at depths exceeding 700m, and how technological innovation will enable humans to enter unendurable realms. The book describes the problems unique to the hostile environment of the deep ocean, such as decompression sickness, discusses how the human body responds to increased pressure, and what happens when adaptive mechanisms fail. Ocean Outpost describes how the technology will evolve, how crews will be selected and trained and what a typical underwater mission will entail. The book also chronicles the frontiers of diving medicine that will eventually take humans into the midst of a world we could once only guess at.

This book was released on 2004-03-02 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ever since the completion of the Apollo program, there has been a lack of consensus about the future of human spaceflight. The Columbia tragedy in February 2003 rekindled public debate about this question. In November 2003, the Space Studies Board and the Aeronautics and Space Engineering Board organized a workshop to explore aspects of the question, what should be the principal purpose, goals, and priorities of the U.S. civil space program? This report presents a factual summary of that workshop, which identified past lessons learned and guiding principles for the future of the civil space program. Seven broad themes emerged from the workshop, and these themes are highlighted in the report. The report also presents discussions of strategies for the human spaceflight program and guiding principles of and boundary conditions for a 21st century space policy.

Download or read book Drawing Louisiana s New Map written by National Research Council and published by National Academies Press. This book was released on 2006-03-23 with total page 205 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the past 50 years, coastal Louisiana has suffered catastrophic land loss due to both natural and human causes. This loss has increased storm vulnerability and amplified risks to lives, property, and economies-a fact underscored by Hurricanes Katrina and Rita. Drawing Louisiana's New Map reviews a restoration plan proposed by the U.S. Army Corps of Engineers and the State of Louisiana, finding that, although the individual projects in the study are scientifically sound, there should be more and larger scale projects that provide a comprehensive approach to addressing land loss over such a large area. More importantly, the study should be guided by a detailed map of the expected future landscape of coastal Louisiana that is developed from agreed upon goals for the region and the nation.
