Download or read book Parachute Recovery Systems written by Theo W. Knacke and published by . This book was released on 1992 with total page 524 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this manual is to provide recovery system engineers in government and industry with tools to evaluate, analyze, select, and design parachute recovery systems. These systems range from simple, one-parachute assemblies to multiple-parachute systems, and may include equipment for impact attenuation, flotation, location, retrieval, and disposition. All system aspects are discussed, including the need for parachute recovery, the selection of the most suitable recovery system concept, concept analysis, parachute performance, force and stress analysis, material selection, parachute assembly and component design, and manufacturing. Experienced recovery system engineers will find this publication useful as a technical reference book; recent college graduates will find it useful as a textbook for learning about parachutes and parachute recovery systems; and technicians with extensive practical experience will find it useful as an engineering textbook that includes a chapter on parachute- related aerodynamics. In this manual, emphasis is placed on aiding government employees in evaluating and supervising the design and application of parachute systems. The parachute recovery system uses aerodynamic drag to decelerate people and equipment moving in air from a higher velocity to a lower velocity and to a safe landing. This lower velocity is known as rate of descent, landing velocity, or impact velocity, and is determined by the following requirements: (1) landing personnel uninjured and ready for action, (2) landing equipment and air vehicles undamaged and ready for use or refurbishment, and (3) impacting ordnance at a preselected angle and velocity.

Download or read book Capital in the Twenty First Century written by Thomas Piketty and published by Harvard University Press. This book was released on 2017-08-14 with total page 817 pages. Available in PDF, EPUB and Kindle. Book excerpt: What are the grand dynamics that drive the accumulation and distribution of capital? Questions about the long-term evolution of inequality, the concentration of wealth, and the prospects for economic growth lie at the heart of political economy. But satisfactory answers have been hard to find for lack of adequate data and clear guiding theories. In this work the author analyzes a unique collection of data from twenty countries, ranging as far back as the eighteenth century, to uncover key economic and social patterns. His findings transform debate and set the agenda for the next generation of thought about wealth and inequality. He shows that modern economic growth and the diffusion of knowledge have allowed us to avoid inequalities on the apocalyptic scale predicted by Karl Marx. But we have not modified the deep structures of capital and inequality as much as we thought in the optimistic decades following World War II. The main driver of inequality--the tendency of returns on capital to exceed the rate of economic growth--today threatens to generate extreme inequalities that stir discontent and undermine democratic values if political action is not taken. But economic trends are not acts of God. Political action has curbed dangerous inequalities in the past, the author says, and may do so again. This original work reorients our understanding of economic history and confronts us with sobering lessons for today.

Download or read book World Development Report 2009 written by World Bank and published by World Bank Publications. This book was released on 2008-11-04 with total page 410 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rising densities of human settlements, migration and transport to reduce distances to market, and specialization and trade facilitated by fewer international divisions are central to economic development. The transformations along these three dimensions density, distance, and division are most noticeable in North America, Western Europe, and Japan, but countries in Asia and Eastern Europe are changing in ways similar in scope and speed. 'World Development Report 2009: Reshaping Economic Geography' concludes that these spatial transformations are essential, and should be encouraged. The conclusion is not without controversy. Slum-dwellers now number a billion, but the rush to cities continues. Globalization is believed to benefit many, but not the billion people living in lagging areas of developing nations. High poverty and mortality persist among the world's 'bottom billion', while others grow wealthier and live longer lives. Concern for these three billion often comes with the prescription that growth must be made spatially balanced. The WDR has a different message: economic growth is seldom balanced, and efforts to spread it out prematurely will jeopardize progress. The Report: documents how production becomes more concentrated spatially as economies grow. proposes economic integration as the principle for promoting successful spatial transformations. revisits the debates on urbanization, territorial development, and regional integration and shows how today's developers can reshape economic geography.
Download or read book The 9 9 Percent written by Matthew Stewart and published by Simon and Schuster. This book was released on 2021-10-12 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: A “brilliant” (The Washington Post), “clear-eyed and incisive” (The New Republic) analysis of how the wealthiest group in American society is making life miserable for everyone—including themselves. In 21st-century America, the top 0.1% of the wealth distribution have walked away with the big prizes even while the bottom 90% have lost ground. What’s left of the American Dream has taken refuge in the 9.9% that lies just below the tip of extreme wealth. Collectively, the members of this group control more than half of the wealth in the country—and they are doing whatever it takes to hang on to their piece of the action in an increasingly unjust system. They log insane hours at the office and then turn their leisure time into an excuse for more career-building, even as they rely on an underpaid servant class to power their economic success and satisfy their personal needs. They have segregated themselves into zip codes designed to exclude as many people as possible. They have made fitness a national obsession even as swaths of the population lose healthcare and grow sicker. They have created an unprecedented demand for admission to elite schools and helped to fuel the dramatic cost of higher education. They channel their political energy into symbolic conflicts over identity in order to avoid acknowledging the economic roots of their privilege. And they have created an ethos of “merit” to justify their advantages. They are all around us. In fact, they are us—or what we are supposed to want to be. In this “captivating account” (Robert D. Putnam, author of Bowling Alone), Matthew Stewart argues that a new aristocracy is emerging in American society and it is repeating the mistakes of history. It is entrenching inequality, warping our culture, eroding democracy, and transforming an abundant economy into a source of misery. He calls for a regrounding of American culture and politics on a foundation closer to the original promise of America.

Download or read book Overtourism written by Claudio Milano and published by CABI. This book was released on 2019-06-07 with total page 265 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book examines the evolution of the phenomenon and explores the genesis of overtourism and the system dynamics underlining it. The 'overtourism' phenomenon is defined as the excessive growth of visitors leading to overcrowding and the consequential suffering of residents, due to temporary and often seasonal tourism peaks, that lead to permanent changes in lifestyles, amenities and well- being. Enormous tensions in overtourism affected destinations have driven the intensification of policy making and scholarly attention toward seeking antidotes to an issue that is considered paradoxical and problematic. Moving beyond the 'top 10 things you can do about overtourism', this book examines the evolution of the phenomenon and explores the genesis of overtourism as well as the system dynamics underpinning it. With a rigorous scientific approach, the book uses systems-thinking and contemporary paradigms around sustainable development, resilience planning and degrowth; while considering global economic, socio-political, environmental discourses. Researchers, analysts, policy makers and industry stakeholders working within tourism as well as those within the private sector, community groups, civil society groups and NGOs will find this book an essential source of information.
