Available in PDF, EPUB and Kindle. Book excerpt: South Dakota Road Profiling (SDRP) systems have been widely sanctioned for use in assessing road roughness and rutting at highway speeds. Traditionally, these high-speed profiling systems have been built around ultrasonic height sensors. More recently, some designs have begun to substitute laser sensors to combat many of the limitations of sound-based equipment. The functional improvements possible with lasers are expensive, however. Whether the potential of lasers for high-speed profiling justifies the great increase in cost was a legitimate question. This report describes the steps that the Virginia Department of Transportation took to address that issue. In general, this research has found that both sensor types are capable of performing very well and with reasonable agreement. Repeatability tests indicated that the roughness indices calculated from laser based profiles are less subject to run-to-run variability than those developed from ultrasonic profiles. Tests to evaluate the effects of vehicle speed and sampling rate on the estimate of roughness have returned less conclusive results. Both tests suggested that the ultrasonic-based data was more highly correlated with the control data (i.e., that based on data collected with the Face Companies' Dipstick R) than the laser-based. The laser data, however, could be shown to be slightly more accurate, on average, than that based on the ultrasonic. Unfortunately, although the performance of the ultrasonic sensors on conventional surfaces has been adequate, their reliability has become a serious concern. In Virginia, humid surveying conditions are often unavoidable and the problem of wet ultrasonics has become more than a simple inconvenience. Hardware reliability may be the most compelling reason to migrate to pure laser roughness measurement. The adoption of only laser-based equipment in future purchases or leases is recommended.

Available in PDF, EPUB and Kindle. Book excerpt: "This project was conducted to describe and evaluate the South Dakota Road Profiler for Demonstration Project 72, 'Evaluation of Equipment for Measuring Pavement Roughness and Rut Depth'. The Road Profiler's profile and rut depth performance were evaluated by comparisons to surveys taken with rod and level and the E.W. Face 'Dipstick'. For each of ten sites, the Road Profiler's measurements at 25, 40 and 55 miles per hour were compared to the manual surveys. Spectral analysis and the International Roughness Index were used to compare profile data, while plots and averages were used to compare rut depth data. The rut Profiler's profile and rut depth measurements correlated well with Dipstick measurements. Minor sensitivity to pavement texture was observed. No operational difficulties were encountered"--Technical report documentation page.

This book was released on 2020-05-01 with total page 369 pages. Available in PDF, EPUB and Kindle. Book excerpt: The delivery of high quality and equitable care for both mothers and newborns is complex and requires efforts across many sectors. The United States spends more on childbirth than any other country in the world, yet outcomes are worse than other high-resource countries, and even worse for Black and Native American women. There are a variety of factors that influence childbirth, including social determinants such as income, educational levels, access to care, financing, transportation, structural racism and geographic variability in birth settings. It is important to reevaluate the United States' approach to maternal and newborn care through the lens of these factors across multiple disciplines. Birth Settings in America: Outcomes, Quality, Access, and Choice reviews and evaluates maternal and newborn care in the United States, the epidemiology of social and clinical risks in pregnancy and childbirth, birth settings research, and access to and choice of birth settings.

Download or read book The Financial Crisis Inquiry Report written by Financial Crisis Inquiry Commission and published by Cosimo, Inc.. This book was released on 2011-05-01 with total page 692 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Financial Crisis Inquiry Report, published by the U.S. Government and the Financial Crisis Inquiry Commission in early 2011, is the official government report on the United States financial collapse and the review of major financial institutions that bankrupted and failed, or would have without help from the government. The commission and the report were implemented after Congress passed an act in 2009 to review and prevent fraudulent activity. The report details, among other things, the periods before, during, and after the crisis, what led up to it, and analyses of subprime mortgage lending, credit expansion and banking policies, the collapse of companies like Fannie Mae and Freddie Mac, and the federal bailouts of Lehman and AIG. It also discusses the aftermath of the fallout and our current state. This report should be of interest to anyone concerned about the financial situation in the U.S. and around the world.THE FINANCIAL CRISIS INQUIRY COMMISSION is an independent, bi-partisan, government-appointed panel of 10 people that was created to "examine the causes, domestic and global, of the current financial and economic crisis in the United States." It was established as part of the Fraud Enforcement and Recovery Act of 2009. The commission consisted of private citizens with expertise in economics and finance, banking, housing, market regulation, and consumer protection. They examined and reported on "the collapse of major financial institutions that failed or would have failed if not for exceptional assistance from the government."News Dissector DANNY SCHECHTER is a journalist, blogger and filmmaker. He has been reporting on economic crises since the 1980's when he was with ABC News. His film In Debt We Trust warned of the economic meltdown in 2006. He has since written three books on the subject including Plunder: Investigating Our Economic Calamity (Cosimo Books, 2008), and The Crime Of Our Time: Why Wall Street Is Not Too Big to Jail (Disinfo Books, 2011), a companion to his latest film Plunder The Crime Of Our Time.

Available in PDF, EPUB and Kindle. Book excerpt: Learn to communicate with your dog—using their language “Good reading for dog lovers and an immensely useful manual for dog owners.”—The Washington Post An Applied Animal Behaviorist and dog trainer with more than twenty years’ experience, Dr. Patricia McConnell reveals a revolutionary new perspective on our relationship with dogs—sharing insights on how “man’s best friend” might interpret our behavior, as well as essential advice on how to interact with our four-legged friends in ways that bring out the best in them. After all, humans and dogs are two entirely different species, each shaped by its individual evolutionary heritage. Quite simply, humans are primates and dogs are canids (as are wolves, coyotes, and foxes). Since we each speak a different native tongue, a lot gets lost in the translation. This marvelous guide demonstrates how even the slightest changes in our voices and in the ways we stand can help dogs understand what we want. Inside you will discover: • How you can get your dog to come when called by acting less like a primate and more like a dog • Why the advice to “get dominance” over your dog can cause problems • Why “rough and tumble primate play” can lead to trouble—and how to play with your dog in ways that are fun and keep him out of mischief • How dogs and humans share personality types—and why most dogs want to live with benevolent leaders rather than “alpha wanna-bes!” Fascinating, insightful, and compelling, The Other End of the Leash is a book that strives to help you connect with your dog in a completely new way—so as to enrich that most rewarding of relationships.
