Book Synopsis An Examination of Statistical Impact Acceleration Injury Prediction Models Based on Torque and Force Variables by : Dennis E. Smith
Download or read book An Examination of Statistical Impact Acceleration Injury Prediction Models Based on Torque and Force Variables written by Dennis E. Smith and published by . This book was released on 1979 with total page 23 pages. Available in PDF, EPUB and Kindle. Book excerpt: This technical report describes the construction of impact acceleration injury prediction models from a set of twenty-eight -G sub x accelerator runs involving Rhesus monkeys with securely restrained torso and unrestrained head. Peak torque and force variables measured during these runs were used to predict injury likelihood. The relative contribution of these variables was examined with respect to the original and a modified version of the data set. Two possible prediction models were used to construct two critical envelopes, i.e., those values of the variables for which the predicted probability of injury (or fatality) is less than or equal to some specified probability. The preferred model was identified and discussed. (Author).
Book Synopsis Research on the Development of a Statistical Impact Acceleration Injury Prediction Model from -G(x) Accelerator Runs by : Dennis E. Smith
Download or read book Research on the Development of a Statistical Impact Acceleration Injury Prediction Model from -G(x) Accelerator Runs written by Dennis E. Smith and published by . This book was released on 1982 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Statistical impact acceleration injury prediction models are developed for the head/neck segment from data obtained during 68 -G sub x accelerator runs. These runs involved subhuman primates (Rhesus monkeys) with securely restrained torso and unrestrained head. The data was collected by the Naval Biodynamics Laboratory (NBDL) as part of its research effort on acceleration impact injury prevention. Three classes of prediction models are constructed, one based on sled profile variables, another based on head dynamic response variables only, and the third comprised of the combined set of independent variables. The model predictions are compared with the observed results to evaluate performance. (Author).
Book Synopsis Statistical Impact Acceleration Injury Prediction Models Based on -G Sub X Accelerator Data by : Carl A. Mauro
Download or read book Statistical Impact Acceleration Injury Prediction Models Based on -G Sub X Accelerator Data written by Carl A. Mauro and published by . This book was released on 1986 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since 1974, the Naval Biodynamics Laboratory (NBDL) has collected, as part of its research effort on acceleration impact injury prevention, an extensive data base from -G sub x accelerator runs on Rhesus subjects. Over this time period, Desmatics, Inc. has been actively involved in the development of statistically based models to predict injury in Rhesus subjects resulting from indirect head/neck impact acceleration in the -X direction. The objectives of the present technical report are: (1) to summarize, update, and consolidate the Desmatics modeling efforts for fatal injury; (2) to investigate extending the injury prediction models to include nonfatal injury criteria; and (3) to evaluate the accuracy and validity of the prediction models obtained in the modeling efforts.

Download or read book An Examination of Statistical Impact Acceleration Injury Prediction Models Based on -Gx Accelerator Data from Subhuman Primates written by Dennis E. Smith and published by . This book was released on 1978 with total page 35 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report considers the application of an impact acceleration injury prediction model to observed data from a set of twenty-eight -G sub x accelerator runs involving subhuman primates (Rhesus monkeys) with securely restrained torso and unrestrained head. The data was collected by the Naval Aerospace Medical Research Laboratory (NAMRL) Detachment as part of its research effort on acceleration impact injury prevention. Using a common data base, two different models were constructed, one based on sled profile variables and the other based on head dynamic response variables. Although the latter model provided a reasonable fit given the small size of the data set, the other model (based on sled profile variables) resulted in a much better fit. Possible explanations for this seemingly anomalous result are listed and additional accelerator runs are suggested. (Author).
Book Synopsis Statistical Impact Acceleration Injury Prediction Models Based on -Gx Accelerator Data and Initial Head Conditions by : Kevin C. Burns
Download or read book Statistical Impact Acceleration Injury Prediction Models Based on -Gx Accelerator Data and Initial Head Conditions written by Kevin C. Burns and published by . This book was released on 1983 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Statistical impact acceleration injury prediction models are developed using data from 23 high-level -G sub X acceleration runs. These runs involve Rhesus monkeys with securely restrained torsos and unrestrained heads. The models are based on peak sled acceleration and initial head conditions. The model predictions are compared with those given in an earlier report based on different data and an estimate of Fisher's information matrix is used to evaluate the relative worth of the two data bases.

Book Synopsis A Study of Estimation Accuracy when Using a Logistic Model for Prediction of Impact Acceleration Injury by : Dennis E. Smith
Download or read book A Study of Estimation Accuracy when Using a Logistic Model for Prediction of Impact Acceleration Injury written by Dennis E. Smith and published by . This book was released on 1978 with total page 35 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report addresses the topic of estimation accuracy in the development of an empirically-based logistic model for predicting impact acceleration injury. Two items of central interest are the degree of accuracy which may be expected for predictions derived from a model and the sensitivity of such predictions to sample size. A Monte Carlo simulation study was undertaken to provide information relating accuracy to sample size for selected model configurations. Two specific sets of model parameters were considered, Monte Carlo samples of various sizes were generated for each, and the accuracy of the resultant predictions were evaluated with respect to the true probabilities. Based on this Monte Carlo study, it appears that the procedure used for estimating the coefficients of the logistic model works well. This procedure provides convergence to the correct coefficient values and true probabilities as the sample size increases. Thus, if injury probability as a function of head dynamic response variables may be approximated by a logistic function, the estimation procedure described in this report will yield a satisfactory approximation to that function.
