This book was released on 2006 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: A procedure was developed for performing a postprocessing heat conduction analysis from a CTH solution for a residual penetrator's shape and temperature field. LS-DYNA was employed for the heat conduction analysis. The interface between CTH and LS-DYNA involved the codes EnSight and HyperMesh. The procedure was applied to perforation of a titanium plate by a steel right circular cylinder at 433 m/s, followed by cookoff of an M30A1 grain by contact with the hot steel residual. The temperature field as a function of time within the M30A1 grain was compared with published data for initiation time as a function of temperature. In an appendix, an analytical solution for heat conduction between two semi-infinite layers is used to assess mesh adequacy in the residual-propellant simulation.

Download or read book Upgrading the Space Shuttle written by National Research Council and published by National Academies Press. This book was released on 1999-02-21 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: The space shuttle is a unique national resource. One of only two operating vehicles that carries humans into space, the space shuttle functions as a scientific laboratory and as a base for construction, repair, and salvage missions in low Earth orbit. It is also a heavy-lift launch vehicle (able to deliver more than 18,000 kg of payload to low Earth orbit) and the only current means of returning large payloads to Earth. Designed in the 1970s, the shuttle has frequently been upgraded to improve safety, cut operational costs, and add capability. Additional upgrades have been proposed-and some are under way-to combat obsolescence, further reduce operational costs, improve safety, and increase the ability of the National Aeronautics and Space Administration (NASA) to support the space station and other missions. In May 1998, NASA asked the National Research Council (NRC) to examine the agency's plans for further upgrades to the space shuttle system. The NRC was asked to assess NASA's method for evaluating and selecting upgrades and to conduct a top-level technical assessment of proposed upgrades.
Download or read book NASA s First 50 Years Historical Perspectives written by Steven J. Dick and published by Createspace Independent Publishing Platform. This book was released on 2010-08-20 with total page 776 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fifty years after the founding of NASA, from 28 to 29 October 2008, the NASA History Division convened a conference whose purpose was a scholarly analysis of NASA's first 50 years. Over two days at NASA Headquarters, historians and policy analysts discussed NASA's role in aeronautics, human spaceflight, exploration, space science, life science, and Earth science, as well as crosscutting themes ranging from space access to international relations in space and NASA's interaction with the public. The speakers were asked to keep in mind the following questions: What are the lessons learned from the first 50 years? What is NASA's role in American culture and in the history of exploration and discovery? What if there had never been a NASA? Based on the past, does NASA have a future? The results of those papers, elaborated and fully referenced, are found in this 50th anniversary volume. The reader will find here, instantiated in the complex institution that is NASA, echoes of perennial themes elaborated in an earlier volume, Critical Issues in the History of Spaceflight. The conference culminated a year of celebrations, beginning with an October 2007 conference celebrating the 50th anniversary of the Space Age and including a lecture series, future forums, publications, a large presence at the Smithsonian Folklife Festival, and numerous activities at NASA's 10 Centers and venues around the country. It took place as the Apollo 40th anniversaries began, ironically still the most famous of NASA's achievements, even in the era of the Space Shuttle, International Space Station (ISS), and spacecraft like the Mars Exploration Rovers (MERs) and the Hubble Space Telescope. And it took place as NASA found itself at a major crossroads, for the first time in three decades transitioning, under Administrator Michael Griffin, from the Space Shuttle to a new Ares launch vehicle and Orion crew vehicle capable of returning humans to the Moon and proceeding to Mars in a program known as Constellation. The Space Shuttle, NASA's launch system since 1981, was scheduled to wind down in 2010, freeing up funds for the new Ares launch vehicle. But the latter, even if it moved forward at all deliberate speed, would not be ready until 2015, leaving the unsettling possibility that for at least five years the United States would be forced to use the Russian Soyuz launch vehicle and spacecraft as the sole access to the ISS in which the United States was the major partner. The presidential elections a week after the conference presaged an imminent presidential transition, from the Republican administration of George W. Bush to (as it turned out) the Democratic presidency of Barack Obama, with all the uncertainties that such transitions imply for government programs. The uncertainties for NASA were even greater, as Michael Griffin departed with the outgoing administration and as the world found itself in an unprecedented global economic downturn, with the benefits of national space programs questioned more than ever before. There was no doubt that 50 years of the Space Age had altered humanity in numerous ways ranging from applications satellites to philosophical world views. Throughout its 50 years, NASA has been fortunate to have a strong sense of history and a robust, independent, and objective history program to document its achievements and analyze its activities. Among its flagship publications are Exploring the Unknown: Selected Documents in the History of the U.S. Civil Space Program, of which seven of eight projected volumes were completed at the time of the 50th anniversary. The reader can do no better than to turn to these volumes for an introduction to NASA history as seen through its primary documents. The list of NASA publications at the end of this volume is also a testimony to the tremendous amount of historical research that the NASA History Division has sponsored over the last 50 years, of which this is the latest volume.
Download or read book Signal Processing for Cognitive Radios written by Sudharman K. Jayaweera and published by John Wiley & Sons. This book was released on 2014-11-19 with total page 763 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book examines signal processing techniques for cognitive radios. The book is divided into three parts: Part I, is an introduction to cognitive radios and presents a history of the cognitive radio (CR), and introduce their architecture, functionalities, ideal aspects, hardware platforms, and state-of-the-art developments. Dr. Jayaweera also introduces the specific type of CR that has gained the most research attention in recent years: the CR for Dynamic Spectrum Access (DSA). Part II of the book, Theoretical Foundations, guides the reader from classical to modern theories on statistical signal processing and inference. The author addresses detection and estimation theory, power spectrum estimation, classification, adaptive algorithms (machine learning), and inference and decision processes. Applications to the signal processing, inference and learning problems encountered in cognitive radios are interspersed throughout with concrete and accessible examples. Part III of the book, Signal Processing in Radios, identifies the key signal processing, inference, and learning tasks to be performed by wideband autonomous cognitive radios. The author provides signal processing solutions to each task by relating the tasks to materials covered in Part II. Specialized chapters then discuss specific signal processing algorithms required for DSA and DSS cognitive radios.

Book excerpt: In 2019, China astonished the world by landing a spacecraft and rover on the far side of the Moon, something never achieved by any country before. China had already become the world’s leading spacefaring nation by rockets launched, sending more into orbit than any other. China is now a great space superpower alongside the United States and Russia, sending men and women into orbit, building a space laboratory (Tiangong) and sending probes to the Moon and asteroids. Roadmap 2050 promises that China will set up bases on the Moon and Mars and lead the world in science and technology by mid-century. China’s space programme is one of the least well-known, but this book will bring the reader up to date with its mysteries, achievements and exciting plans. China has built a fleet of new, powerful Long March rockets, four launch bases, tracking stations at home and abroad, with gleaming new design and production facilities. China is poised to build a large, permanent space station, bring back lunar rocks, assemble constellations of communications satellites and send spaceships to Mars, the moons of Jupiter and beyond. A self-sustaining lunar base, Yuegong, has already been simulated. In space, China is the country to watch.
