Available in PDF, EPUB and Kindle. Book excerpt: Ballistic Missile and Space Technology, Volume IV: Re-Entry and Vehicle Design focuses on the advancements of processes, methodologies, and technologies involved in re-entry and vehicle design, including hypersonics, material structures, propulsion, and communications. The selection first offers information on the pyrolysis of plastics in a high vacuum arc image furnace and aerothermodynamic feasibility of graphite for hypersonic glide vehicles. Discussions focus on aerothermochemical behavior of graphite, transient heat conduction, equilibrium glide trajectory, and apparatus and pyrolysis procedure. The text then takes a look at an engineering analysis of the weights of ablating systems for manned reentry vehicles and trajectories of lifting bodies entering planetary atmospheres at shallow angles. The manuscript ponders on propulsive control of atmospheric entry lifting trajectories, re-entry engineering mechanics, and rocket casing behavior predicted by laboratory tests. Topics include description of testing program, full-scale casing results, camera design, theoretical correlation, approximate thrust vector optimization, and propellant weight estimation. The selection is a dependable reference for astronauts and researchers interested in re-entry and vehicle design.

Download or read book Reusable Launch Vehicle written by Committee on Reusable Launch Vehicle Technology and Test Program and published by National Academies Press. This book was released on 1996-01-22 with total page 99 pages. Available in PDF, EPUB and Kindle. Book excerpt: The key to opening the use of space to private enterprise and to broader public uses lies in reducing the cost of the transportation to space. More routine, affordable access to space will entail aircraft-like quick turnaround and reliable operations. Currently, the space Shuttle is the only reusable launch vehicle, and even parts of it are expendable while other parts require frequent and extensive refurbishment. NASA's highest priority new activity, the Reusable Launch Vehicle program, is directed toward developing technologies to enable a new generation of space launchers, perhaps but not necessarily with single stage to orbit capability. This book assesses whether the technology development, test and analysis programs in propulsion and materials-related technologies are properly constituted to provide the information required to support a December 1996 decision to build the X-33, a technology demonstrator vehicle; and suggest, as appropriate, necessary changes in these programs to ensure that they will support vehicle feasibility goals.

Download or read book Offender Reentry written by Matthew S Crow and published by Jones & Bartlett Publishers. This book was released on 2013-04-24 with total page 487 pages. Available in PDF, EPUB and Kindle. Book excerpt: An Innovative New Text That Addresses a Critical Issue Nearly 2,000 people are released from prison every day in the United States, many of whom face significant barriers to re-entry into the civilian population. Within three years, two-thirds of them will be rearrested, and nearly half will return to prison for a new crime or parole violation. Offender Reentry: Rethinking Criminology and Criminal Justice is the first text of its kind to address this major issue in criminology and criminal justice. Bringing together cutting-edge and never-before-published research, and authored by the most critically recognized experts in the field, this text offers students extraordinary insight into the experiences of both offenders in reentry and the practitioners who work within the legal system. Real-world stories from criminal justice professionals and offenders themselves are integrated with up-to-the minute research and thought-provoking analysis. Student-oriented pedagogical features, including critical-thinking and discussion questions for every chapter, push students to engage deeply with the text and synthesize their own innovative solutions to contemporary problems. The text addresses all of the societal factors that affect offender reentry, as well as the political and economic effects on the community and issues of public safety. Ideally suited for upper-level undergraduate and graduate courses in criminal justice and criminology, Offender Reentry is an invaluable new addition to the field.

Download or read book Limiting Future Collision Risk to Spacecraft written by National Research Council and published by National Academies Press. This book was released on 2011-12-16 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: Derelict satellites, equipment and other debris orbiting Earth (aka space junk) have been accumulating for many decades and could damage or even possibly destroy satellites and human spacecraft if they collide. During the past 50 years, various National Aeronautics and Space Administration (NASA) communities have contributed significantly to maturing meteoroid and orbital debris (MMOD) programs to their current state. Satellites have been redesigned to protect critical components from MMOD damage by moving critical components from exterior surfaces to deep inside a satellite's structure. Orbits are monitored and altered to minimize the risk of collision with tracked orbital debris. MMOD shielding added to the International Space Station (ISS) protects critical components and astronauts from potentially catastrophic damage that might result from smaller, untracked debris and meteoroid impacts. Limiting Future Collision Risk to Spacecraft: An Assessment of NASA's Meteoroid and Orbital Debris Program examines NASA's efforts to understand the meteoroid and orbital debris environment, identifies what NASA is and is not doing to mitigate the risks posed by this threat, and makes recommendations as to how they can improve their programs. While the report identified many positive aspects of NASA's MMOD programs and efforts including responsible use of resources, it recommends that the agency develop a formal strategic plan that provides the basis for prioritizing the allocation of funds and effort over various MMOD program needs. Other necessary steps include improvements in long-term modeling, better measurements, more regular updates of the debris environmental models, and other actions to better characterize the long-term evolution of the debris environment.

Eisenhower to pull various pieces together to create the National Aeronautics and Space Administration.

Download or read book Lightning Bolts written by William Yengst and published by Tate Publishing. This book was released on 2010-04 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: History shows that demands of wartime military and political leaders have often motivated development of new and advanced technologies. The German desire to attack American cities with long-range variants of V-2 missiles during the latter years of World War II stimulated development of maneuvering reentry vehicle concepts. In the mid-1960s, these concepts were secretly refined and tested by the United States to provide accurate delivery of strategic nuclear warheads at intercontinental ranges and to assure their penetration of newly developed Soviet anti-ballistic missile defenses. First Maneuvering Reentry Vehicles, by William C. Yengst, describes the initial feasibility programs to test three alternative designs for implementing hypersonic maneuvers and accurate guidance of long-range reentry vehicles. It identifies the political and military motivations, environmental challenges, design difficulties, innovative technology solutions, test failures, and spectacular successes. It also summarizes development of operational maneuvering reentry vehicles prepared for U.S. Air Force, Navy, and Army long-range missile systems during the 1980s. The technology has been adopted and further refined by foreign nations (India, China and Russia) in building their latest missile systems. Therefore, it is important to understand the capabilities and performance characteristics of future potential threats. Written as a first-hand account of the technology's evolution, the book honors the dedicated engineers and scientists who worked to make these programs a success.

Download or read book Mothering and Desistance in Re Entry written by Venezia Michalsen and published by Routledge. This book was released on 2018-11-05 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although there is plentiful research on the impact of marriage, employment and the military on desistance from criminal behaviour in the lives of men, far less is known about the factors most important to women’s desistance. Imprisoned women are far more likely than their male counterparts to be the primary caretakers of children before their incarceration, and are far more likely to intend to reunify with their children upon their release from incarceration. This book focuses on the role of mothering in women’s desistance from criminal behaviour. Drawing on original research, this book explores the nature of mothering during incarceration, how mothers maintain a relationship with their children from behind bars and the ways in which mothering makes desistance more or less likely after incarceration. It outlines the ways in which race, gender, class, nationality, sexuality, gender identity, and other characteristics affect mothering and desistance, and explores the tensions between individual and system-level factors in the consideration of desistance. This book suggests that any discussion of desistance, particularly for women, must move beyond the traditional focus on individual characteristics and decision-making. Such a focus overlooks the role played by context and systems which undermine both women's attempts to be mothers and their attempts to desist. By contrast, in the tradition of Beth Richie’s Compelled to Crime, this book explores both the trees and the forests, and the quantum in-between, in a way that aims for lasting societal and individual changes.

Download or read book Re Entry written by Michelle Matthews and published by iUniverse. This book was released on 2012-03-15 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: When author Michelle Matthews came home from war, she thought returning alive meant the worst was over. She was mistaken; surviving life after war proved to be equally challenging. Matthews returned a changed person. In Re-entry, she narrates a poignant account of the war in Iraq, its tragic aftermath, and her courageous journey to heal emotionally. Based on journal entries and e-mails sent before, during, and after her service in Iraq, this memoir provides a firsthand account of the trials and tribulations she experienced by her service and gives insight into her emotional journey. Upon her return, Matthews struggled with anxiety and depression and began overeating and abusing alcohol. She tells how she wrestled with thoughts of suicide as she found normal life overwhelming following the abnormal rhythm of war. Re-entry shows that how, through counseling, physical and recreational therapy, journaling, meditating, exercising, and support from family and friends, Matthews found herself again.

Download or read book Properties of Re Entry Materials written by Seymour A. Bortz and published by . This book was released on 1971 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: The engineering and design data characterizing new reentry materials are evaluated. Materials studied were a molded carbon cloth phenolic composite (REST 6300), and a pierced fabric composite. Tests were also conducted on FRP Teflon which is being employed for behavioral studies under reentry conditions. REST 6300 was evaluated for mechanical strength, elastic modulus, strain to failure, and thermal expansion at various temperatures up to 6000 F. Precharring was used to reduce the effect of time on char conditions during testing. All property measurements were evaluated and related to the temperature of the test conditions. The FEP Teflon was evaluated for shear and compression strength and modulus, viscosity, and stress relaxation over a temperature range from room temperature to 450 F. These experiments provided material properties which could be used to verify material response theories developed to explain cross hatching phenomena which may occur in a re-entry environment.

Download or read book When Prisoners Come Home written by Joan Petersilia and published by Oxford University Press. This book was released on 2009-04-21 with total page 307 pages. Available in PDF, EPUB and Kindle. Book excerpt: Every year, hundreds of thousands of jailed Americans leave prison and return to society. Largely uneducated, unskilled, often without family support, and with the stigma of a prison record hanging over them, many if not most will experience serious social and psychological problems after release. Fewer than one in three prisoners receive substance abuse or mental health treatment while incarcerated, and each year fewer and fewer participate in the dwindling number of vocational or educational pre-release programs, leaving many all but unemployable. Not surprisingly, the great majority is rearrested, most within six months of their release. What happens when all those sent down the river come back up--and out? As long as there have been prisons, society has struggled with how best to help prisoners reintegrate once released. But the current situation is unprecedented. As a result of the quadrupling of the American prison population in the last quarter century, the number of returning offenders dwarfs anything in America's history. What happens when a large percentage of inner-city men, mostly Black and Hispanic, are regularly extracted, imprisoned, and then returned a few years later in worse shape and with dimmer prospects than when they committed the crime resulting in their imprisonment? What toll does this constant "churning" exact on a community? And what do these trends portend for public safety? A crisis looms, and the criminal justice and social welfare system is wholly unprepared to confront it. Drawing on dozens of interviews with inmates, former prisoners, and prison officials, Joan Petersilia convincingly shows us how the current system is failing, and failing badly. Unwilling merely to sound the alarm, Petersilia explores the harsh realities of prisoner reentry and offers specific solutions to prepare inmates for release, reduce recidivism, and restore them to full citizenship, while never losing sight of the demands of public safety. As the number of ex-convicts in America continues to grow, their systemic marginalization threatens the very society their imprisonment was meant to protect. America spent the last decade debating who should go to prison and for how long. Now it's time to decide what to do when prisoners come home.
