Download or read book Low Energy Lunar Trajectory Design written by Jeffrey S. Parker and published by John Wiley & Sons. This book was released on 2014-06-25 with total page 452 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on years of research conducted at the NASA Jet Propulsion Laboratory, Low-Energy Lunar Trajectory Design provides high-level information to mission managers and detailed information to mission designers about low-energy transfers between Earth and the moon. The book answers high-level questions about the availability and performance of such transfers in any given month and year. Low-energy lunar transfers are compared with various other types of transfers, and placed within the context of historical missions. Using this book, designers may reconstruct any transfer described therein, as well as design similar transfers with particular design parameters. An Appendix, “Locating the Lagrange Points,” and a useful list of terms and constants completes this technical reference. Surveys thousands of possible trajectories that may be used to transfer spacecraft between Earth and the moon, including transfers to lunar libration orbits, low lunar orbits, and the lunar surface Provides information about the methods, models, and tools used to design low-energy lunar transfers Includes discussion about the variations of these transfers from one month to the next, and the important operational aspects of implementing a low-energy lunar transfer Additional discussions address navigation, station-keeping, and spacecraft systems issues
Download or read book NASA Space Technology Roadmaps and Priorities written by National Research Council and published by National Academies Press. This book was released on 2012-06-07 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: NASA's Office of the Chief Technologist (OCT) has begun to rebuild the advanced space technology program in the agency with plans laid out in 14 draft technology roadmaps. It has been years since NASA has had a vigorous, broad-based program in advanced space technology development and its technology base has been largely depleted. However, success in executing future NASA space missions will depend on advanced technology developments that should already be underway. Reaching out to involve the external technical community, the National Research Council (NRC) considered the 14 draft technology roadmaps prepared by OCT and ranked the top technical challenges and highest priority technologies that NASA should emphasize in the next 5 years. This report provides specific guidance and recommendations on how the effectiveness of the technology development program managed by OCT can be enhanced in the face of scarce resources.

Download or read book Learning to Think Spatially written by National Research Council and published by National Academies Press. This book was released on 2005-02-03 with total page 333 pages. Available in PDF, EPUB and Kindle. Book excerpt: Learning to Think Spatially examines how spatial thinking might be incorporated into existing standards-based instruction across the school curriculum. Spatial thinking must be recognized as a fundamental part of Kâ€"12 education and as an integrator and a facilitator for problem solving across the curriculum. With advances in computing technologies and the increasing availability of geospatial data, spatial thinking will play a significant role in the information-based economy of the twenty-first century. Using appropriately designed support systems tailored to the Kâ€"12 context, spatial thinking can be taught formally to all students. A geographic information system (GIS) offers one example of a high-technology support system that can enable students and teachers to practice and apply spatial thinking in many areas of the curriculum.

Download or read book The Presentation of Self in Everyday Life written by Erving Goffman and published by Anchor. This book was released on 2021-09-29 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: A notable contribution to our understanding of ourselves. This book explores the realm of human behavior in social situations and the way that we appear to others. Dr. Goffman uses the metaphor of theatrical performance as a framework. Each person in everyday social intercourse presents himself and his activity to others, attempts to guide and cotnrol the impressions they form of him, and employs certain techniques in order to sustain his performance, just as an actor presents a character to an audience. The discussions of these social techniques offered here are based upon detailed research and observation of social customs in many regions.

Available in PDF, EPUB and Kindle. Book excerpt: "A brilliant, witty, and altogether satisfying book." — New York Times Book Review The classic work on the development of human language by the world’s leading expert on language and the mind In The Language Instinct, the world's expert on language and mind lucidly explains everything you always wanted to know about language: how it works, how children learn it, how it changes, how the brain computes it, and how it evolved. With deft use of examples of humor and wordplay, Steven Pinker weaves our vast knowledge of language into a compelling story: language is a human instinct, wired into our brains by evolution. The Language Instinct received the William James Book Prize from the American Psychological Association and the Public Interest Award from the Linguistics Society of America. This edition includes an update on advances in the science of language since The Language Instinct was first published.
Download or read book An Evolutionary Theory of Economic Change written by Richard R. Nelson and published by Harvard University Press. This book was released on 1985-10-15 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains the most sustained and serious attack on mainstream, neoclassical economics in more than forty years. Nelson and Winter focus their critique on the basic question of how firms and industries change overtime. They marshal significant objections to the fundamental neoclassical assumptions of profit maximization and market equilibrium, which they find ineffective in the analysis of technological innovation and the dynamics of competition among firms. To replace these assumptions, they borrow from biology the concept of natural selection to construct a precise and detailed evolutionary theory of business behavior. They grant that films are motivated by profit and engage in search for ways of improving profits, but they do not consider them to be profit maximizing. Likewise, they emphasize the tendency for the more profitable firms to drive the less profitable ones out of business, but they do not focus their analysis on hypothetical states of industry equilibrium. The results of their new paradigm and analytical framework are impressive. Not only have they been able to develop more coherent and powerful models of competitive firm dynamics under conditions of growth and technological change, but their approach is compatible with findings in psychology and other social sciences. Finally, their work has important implications for welfare economics and for government policy toward industry.

Download or read book The Challenge of Crime in a Free Society written by United States. President's Commission on Law Enforcement and Administration of Justice and published by . This book was released on 1967 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report of the President's Commission on Law Enforcement and Administration of Justice -- established by President Lyndon Johnson on July 23, 1965 -- addresses the causes of crime and delinquency and recommends how to prevent crime and delinquency and improve law enforcement and the administration of criminal justice. In developing its findings and recommendations, the Commission held three national conferences, conducted five national surveys, held hundreds of meetings, and interviewed tens of thousands of individuals. Separate chapters of this report discuss crime in America, juvenile delinquency, the police, the courts, corrections, organized crime, narcotics and drug abuse, drunkenness offenses, gun control, science and technology, and research as an instrument for reform. Significant data were generated by the Commission's National Survey of Criminal Victims, the first of its kind conducted on such a scope. The survey found that not only do Americans experience far more crime than they report to the police, but they talk about crime and the reports of crime engender such fear among citizens that the basic quality of life of many Americans has eroded. The core conclusion of the Commission, however, is that a significant reduction in crime can be achieved if the Commission's recommendations (some 200) are implemented. The recommendations call for a cooperative attack on crime by the Federal Government, the States, the counties, the cities, civic organizations, religious institutions, business groups, and individual citizens. They propose basic changes in the operations of police, schools, prosecutors, employment agencies, defenders, social workers, prisons, housing authorities, and probation and parole officers.
