This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Background: An Instrumented Spatial Linkage (ISL) was developed to measure changes, caused by total knee arthroplasty (TKA), in the two kinematic axes of the tibiofemoral joint: the flexion-extension (F-E) axis and the longitudinal rotation (LR) axes. The objectives were to 1) determine both the optimal size of an ISL and position of attachment to the joint and the best pattern of applied motion such that measurement errors are minimized, and 2) construct, calibrate, and validate this ISL. Methods: A mathematical model of a virtual ISL that measured motion across a virtual tibiofemoral joint was created in MATLAB. Both the best pattern of applied motion and the best ISL size and position were determined, which minimized the position and orientation errors due to common encoder errors. The optimal ISL was constructed and calibrated using a novel method. Validation was performed using an adjustable fixture to quantify the error in measuring changes in the F-E and LR axes. Results: The optimal ISL was determined and an ISL was constructed following those guidelines. The best pattern of motion was determined and used in the subsequent validation. For the calibration, the resulting root mean squared errors were each below 0.29% of the respective full-scale range. When measuring changes to the F-E or LR axes, each orientation error was below 0.5 deg. When measuring changes in the F-E axis, each position error was below 1.0 mm. Discussion: The mathematical model developed herein could be used to determine the errors for any ISL size and position, any applied motion, and potentially any anatomical joint. Despite the large size of the ISL, the calibration residuals were better than those for previously published ISLs. Validation demonstrated that this ISL is capable of accurately measuring clinically important changes in the F-E and LR axes.

This book was released on 2012-12-06 with total page 421 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 34 (thesis year 1989) a total of 13,377 theses titles from 26 Canadian and 184 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work. While Volume 34 reports theses submitted in 1989, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.

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.
