Abstract
Transport of neonatal patients between critical care units can expose patients to whole-body vibrations which may pose a risk to the vulnerable patients' health. The concern for patient safety has motivated a study on characterizing and mitigating vibrations transmitted by the Neonatal Patient Transport System (NPTS) that is used in ground and air ambulances in Ontario. To supplement invehicle testing, a simulation is being developed to replicate the motion of the NPTS. The first stage of developing this model involves simulating a planar representation of the NPTS in order to identify unknown system parameters. This paper outlines the derivation of equations of motion of the NPTS in the roll plane by applying the Newton-Euler method. The acceleration power spectral density (PSD) of the simulated motion is compared against recorded road test data to aid in tuning the system parameters. Simulated results show similar frequency responses for the vertical motion of the system. However, the roll direction deviates from the measured response. Further optimization is required to calibrate and validate this model to ensure it represents the angular motion of the system and reproduces behaviour exhibited in various transport conditions.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
