Download or read book A Study of Angle of Attack at Bridges and the PREFES Program written by A. David Parr and published by . This book was released on 1996 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report includes descriptions of three computer programs developed to enable practicing engineers to make use of the two-dimensional finite element model FESWMS-2DH for the analysis of scour at single opening bridges. Multiple opening bridges could be analyzed one opening at a time after using WSPRO to determine the division of flow for each opening. The executable versions of the programs are available. The program descriptions are as follows: PREFES is a preprocessor for FESWMS-2DH which is described in detail in the report. The program PREFES creates the finite element grid input file and various other files required to run FESWMS-2DH. It is designed to create close to the maximum allowable number of finite element nodes with the greatest node density through the bridge opening. This results in very precise flow modeling by FESWMS-2DH. Reliable estimates of angle of attack, velocity magnitude and approach depth can be obtained for scour calculations.

Download or read book Command Of The Air written by General Giulio Douhet and published by Pickle Partners Publishing. This book was released on 2014-08-15 with total page 620 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the pantheon of air power spokesmen, Giulio Douhet holds center stage. His writings, more often cited than perhaps actually read, appear as excerpts and aphorisms in the writings of numerous other air power spokesmen, advocates-and critics. Though a highly controversial figure, the very controversy that surrounds him offers to us a testimonial of the value and depth of his work, and the need for airmen today to become familiar with his thought. The progressive development of air power to the point where, today, it is more correct to refer to aerospace power has not outdated the notions of Douhet in the slightest In fact, in many ways, the kinds of technological capabilities that we enjoy as a global air power provider attest to the breadth of his vision. Douhet, together with Hugh “Boom” Trenchard of Great Britain and William “Billy” Mitchell of the United States, is justly recognized as one of the three great spokesmen of the early air power era. This reprint is offered in the spirit of continuing the dialogue that Douhet himself so perceptively began with the first edition of this book, published in 1921. Readers may well find much that they disagree with in this book, but also much that is of enduring value. The vital necessity of Douhet’s central vision-that command of the air is all important in modern warfare-has been proven throughout the history of wars in this century, from the fighting over the Somme to the air war over Kuwait and Iraq.

Download or read book The Search for HMAS Sydney written by Ted Graham and published by UNSW Press. This book was released on 2014-09-01 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: In November 1941 HMAS Sydney, the pride of Australia's wartime fleet, and its crew of 645 disappeared without a trace off the Western Australian coast. All that was known was Sydney had come under fire from the German raider HSK Kormoran, which also sank. After numerous unsuccessful searches from the mid 1970s onwards, the Finding Sydney Foundation was set up and in March 2008 one of Australia's greatest maritime mysteries was solved when both wrecks were finally discovered. The Search for HMAS Sydney pieces together the incredible story of Sydney, its crew and the families left behind. It details the innovative and powerful research procedures implemented by the Foundation to locate the wrecks of Sydney and Kormoran, their discovery and the detailed forensic analyses and commemorations that followed.

Download or read book Strengthening Forensic Science in the United States written by National Research Council and published by National Academies Press. This book was released on 2009-07-29 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scores of talented and dedicated people serve the forensic science community, performing vitally important work. However, they are often constrained by lack of adequate resources, sound policies, and national support. It is clear that change and advancements, both systematic and scientific, are needed in a number of forensic science disciplines to ensure the reliability of work, establish enforceable standards, and promote best practices with consistent application. Strengthening Forensic Science in the United States: A Path Forward provides a detailed plan for addressing these needs and suggests the creation of a new government entity, the National Institute of Forensic Science, to establish and enforce standards within the forensic science community. The benefits of improving and regulating the forensic science disciplines are clear: assisting law enforcement officials, enhancing homeland security, and reducing the risk of wrongful conviction and exoneration. Strengthening Forensic Science in the United States gives a full account of what is needed to advance the forensic science disciplines, including upgrading of systems and organizational structures, better training, widespread adoption of uniform and enforceable best practices, and mandatory certification and accreditation programs. While this book provides an essential call-to-action for congress and policy makers, it also serves as a vital tool for law enforcement agencies, criminal prosecutors and attorneys, and forensic science educators.
