Abstract

fetched live from OpenAlex

<div class="htmlview paragraph">The purpose of this study was to develop 3D digital ‘boundary manikins’ that are representative of the anthropometry of a unique population. These digital manikins can be used by designers to verify and validate that the components of the spacesuit design satisfy the requirements specified in the Human Systems Integration Requirements (HSIR) document. Currently, the HSIR requires the next generation space suit to accommodate the 1<sup>st</sup> percentile American female to the 99<sup>th</sup> percentile American male.</div> <div class="htmlview paragraph">The manikin anthropometry was derived using two methods: Principal Component Analysis (PCA) and Whole Body Posture Based Analysis (WBPBA). PCA is a statistical method for reducing a multidimensional data set by using eigenvectors and eigenvalues. The goal was to create a reduced data set that encapsulates the majority of the variation in the population. WBPBA is a multivariate analytical approach that was developed by the Anthropometry and Biomechanics Facility (ABF) to identify the extremes of a population for a given body posture. WBPBA is a simulation-based method that finds extremes in a population based upon anthropometry and posture; whereas PCA is based solely on anthropometry.</div> <div class="htmlview paragraph">Both methods yielded a list of subjects and their anthropometry from a target population; PCA resulted in 20 female and 22 male subjects' anthropometry and WBPBA resulted in 7 subjects' anthropometry representing the extreme subjects in the target population. The subjects' anthropometry was then used to ‘morph’ a baseline digital scan of a person with the same body type to create a 3D digital model that can be used as a tool for designers.</div>

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
