Available in PDF, EPUB and Kindle. Book excerpt: November, 2008 Anna Schwarz, Johannes Janicka In the last thirty years noise emission has developed into a topic of increasing importance to society and economy. In ?elds such as air, road and rail traf?c, the control of noise emissions and development of associated noise-reduction techno- gies is a central requirement for social acceptance and economical competitiveness. The noise emission of combustion systems is a major part of the task of noise - duction. The following aspects motivate research: • Modern combustion chambers in technical combustion systems with low pol- tion exhausts are 5 - 8 dB louder compared to their predecessors. In the ope- tional state the noise pressure levels achieved can even be 10-15 dB louder. • High capacity torches in the chemical industry are usually placed at ground level because of the reasons of noise emissions instead of being placed at a height suitable for safety and security. • For airplanes the combustion emissions become a more and more important topic. The combustion instability and noise issues are one major obstacle for the introduction of green technologies as lean fuel combustion and premixed burners in aero-engines. The direct and indirect contribution of combustion noise to the overall core noise is still under discussion. However, it is clear that the core noise besides the fan tone will become an important noise source in future aero-engine designs. To further reduce the jet noise, geared ultra high bypass ratio fans are driven by only a few highly loaded turbine stages.

Download or read book Computational Aeroacoustics written by Christopher K. W. Tam and published by Cambridge University Press. This book was released on 2012-09-28 with total page 497 pages. Available in PDF, EPUB and Kindle. Book excerpt: Computational aeroacoustics (CAA) is a relatively new research area. CAA algorithms have developed rapidly and the methods have been applied in many areas of aeroacoustics. The objective of CAA is not simply to develop computational methods but also to use these methods to solve practical aeroacoustics problems and to perform numerical simulation of aeroacoustic phenomena. By analysing the simulation data, an investigator can determine noise generation mechanisms and sound propagation processes. This is both a textbook for graduate students and a reference for researchers in CAA and as such is self-contained. No prior knowledge of numerical methods for solving partial differential equations (PDEs) is needed, however, a general understanding of partial differential equations and basic numerical analysis is assumed. Exercises are included and are designed to be an integral part of the chapter content. In addition, sample computer programs are included to illustrate the implementation of the numerical algorithms.

Available in PDF, EPUB and Kindle. Book excerpt: NEW YORK TIMES BESTSELLER • A heartwarming gift for the holidays—a powerful selection of the letters Tom Brokaw received in response to his towering #1 bestseller The Greatest Generation. “When I wrote about the men and women who came out of the Depression, who won great victories and made lasting sacrifices in World War II and then returned home to begin building the world we have today—the people I called the Greatest Generation—it was my way of saying thank you. But I was not prepared for the avalanche of letters and responses touched off by that book. I had written a book about America, and now America was writing back.”—Tom Brokaw In the phenomenal bestseller The Greatest Generation, Tom Brokaw paid affecting tribute to those who gave the world so much—and who left an enduring legacy of courage and conviction. The Greatest Generation Speaks collects the vast outpouring of letters Brokaw received from men and women eager to share their intensely personal stories of a momentous time in America’s history. Some letters tell of the front during the war, others recall loved ones in harm’s way in distant places. They offer first-hand accounts of battles, poignant reflections on loneliness, exuberant expressions of love, and somber feelings of loss. As Brokaw notes, “If we are to heed the past to prepare for the future, we should listen to these quiet voices of a generation that speaks to us of duty and honor, sacrifice and accomplishment. I hope more of their stories will be preserved and cherished as reminders of all that we owe them and all that we can learn from them.”

Download or read book Embedding Ethics written by Lynn Meskell and published by Routledge. This book was released on 2020-05-27 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: Anthropologists who talk about ethics generally mean the code of practice drafted by a professional association for implementation by its members. As this book convincingly shows, such a conception is far too narrow. A more radical approach is to recognize that moral judgments are made at every juncture of scientific practice and they require a negotiation of responsibility with all stakeholders in the research enterprise.Embedding Ethics questions why ethics have been divorced from scientific expertise. Invoking different disciplinary practices from biological, archaeological, cultural, and linguistic anthropology, contributors show how ethics should be resituated at the heart of, rather than exterior to, scientific activity. Positioning the researcher as a negotiator of significant truths rather than an adjudicator of a priori precepts enables contributors to relocate ethics in new sets of social and scientific relationships triggered by recent globalization processes - from new forms of intellectual and cultural ownership to accountability in governance, and the very ways in which people are studied. Case studies from ethnographic research, museum display, archaeological fieldwork and professional monitoring illustrate both best practice and potential pitfalls.This important book is an essential guide for all anthropologists who wish to be active contributors to the discussion on ethics and the ethical practice of their profession.

Download or read book The Development of Propulsion Technology for U S Space Launch Vehicles 1926 1991 written by J. D. Hunley and published by Texas A&M University Press. This book was released on 2013-03-15 with total page 398 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this definitive study, J. D. Hunley traces the program’s development from Goddard’s early rockets (and the German V-2 missile) through the Titan IVA and the Space Shuttle, with a focus on space-launch vehicles. Since these rockets often evolved from early missiles, he pays considerable attention to missile technology, not as an end in itself, but as a contributor to launch-vehicle technology. Focusing especially on the engineering culture of the program, Hunley communicates this very human side of technological development by means of anecdotes, character sketches, and case studies of problems faced by rocket engineers. He shows how such a highly adaptive approach enabled the evolution of a hugely complicated technology that was impressive—but decidedly not rocket science. Unique in its single-volume coverage of the evolution of launch-vehicle technology from 1926 to 1991, this meticulously researched work will inform scholars and engineers interested in the history of technology and innovation, as well as those specializing in the history of space flight.

Download or read book The Adaptation Industry written by Simone Murray and published by Routledge. This book was released on 2012-03-12 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: Adaptation constitutes the driving force of contemporary culture, with stories adapted across an array of media formats. However, adaptation studies has been concerned almost exclusively with textual analysis, in particular with compare-and-contrast studies of individual novel and film pairings. This has left almost completely unexamined crucial questions of how adaptations come to be made, what are the industries with the greatest stake in making them, and who the decision-makers are in the adaptation process. The Adaptation Industry re-imagines adaptation not as an abstract process, but as a material industry. It presents the adaptation industry as a cultural economy of six interlocking institutions, stakeholders and decision-makers all engaged in the actual business of adapting texts: authors; agents; publishers; book prize committees; scriptwriters; and screen producers and distributors. Through trading in intellectual property rights to cultural works, these six nodal points in the adaptation network are tightly interlinked, with success for one party potentially auguring for success in other spheres. But marked rivalries between these institutional forces also exist, with competition characterizing every aspect of the adaptation process. This book constructs an overdue sociology of contemporary literary adaptation, never losing sight of the material and institutional dimensions of this powerful process.

Download or read book The Waterworks written by E.L. Doctorow and published by Random House. This book was released on 2010-11-17 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: “An elegant page-turner of nineteenth-century detective fiction.” –The Washington Post Book World One rainy morning in 1871 in lower Manhattan, Martin Pemberton a freelance writer, sees in a passing stagecoach several elderly men, one of whom he recognizes as his supposedly dead and buried father. While trying to unravel the mystery, Pemberton disappears, sending McIlvaine, his employer, the editor of an evening paper, in pursuit of the truth behind his freelancer’s fate. Layer by layer, McIlvaine reveals a modern metropolis surging with primordial urges and sins, where the Tweed Ring operates the city for its own profit and a conspicuously self-satisfied nouveau-riche ignores the poverty and squalor that surrounds them. In E. L. Doctorow’s skilled hands, The Waterworks becomes, in the words of The New York Times, “a dark moral tale . . . an eloquently troubling evocation of our past.” “Startling and spellbinding . . . The waters that lave the narrative all run to the great confluence, where the deepest issues of life and death are borne along on the swift, sure vessel of [Doctorow’s] poetic imagination.” –The New York Times Book Review “Hypnotic . . . a dazzling romp, an extraordinary read, given strength and grace by the telling, by the poetic voice and controlled cynical lyricism of its streetwise and world-weary narrator.” –The Philadelphia Inquirer “A gem of a novel, intimate as chamber music . . . a thriller guaranteed to leave readers with residual chills and shudders.” –Boston Sunday Herald “Enthralling . . . a story of debauchery and redemption that is spellbinding from first page to last.” –Chicago Sun-Times “An immense, extraordinary achievement.” –San Francisco Chronicle

Download or read book Polyglutamine Disorders written by Clévio Nóbrega and published by Springer. This book was released on 2018-02-09 with total page 467 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a cutting-edge review of polyglutamine disorders. It primarily focuses on two main aspects: (1) the mechanisms underlying the pathologies’ development and progression, and (2) the therapeutic strategies that are currently being explored to stop or delay disease progression. Polyglutamine (polyQ) disorders are a group of inherited neurodegenerative diseases with a fatal outcome that are caused by an abnormal expansion of a coding trinucleotide repeat (CAG), which is then translated in an abnormal protein with an elongated glutamine tract (Q). To date, nine polyQ disorders have been identified and described: dentatorubral-pallidoluysian atrophy (DRPLA); Huntington’s disease (HD); spinal–bulbar muscular atrophy (SBMA); and six spinocerebellar ataxias (SCA 1, 2, 3, 6, 7, and 17). The genetic basis of polyQ disorders is well established and described, and despite important advances that have opened up the possibility of generating genetic models of the disease, the mechanisms that cause neuronal degeneration are still largely unknown and there is currently no treatment available for these disorders. Further, it is believed that the different polyQ may share some mechanisms and pathways contributing to neurodegeneration and disease progression.
