Validating MOTAN: Results from Model-Scale Impact Tests with the CCGS TERRY FOX
Bibliographic record
Abstract
This paper describes a model-scale test program that was designed to simulate the type of impacts that occurred during the Bergy Bit Trials. The model tests were conducted as part of a validation study of the inertial measurement system called MOTAN. Various types of controlled impact tests were conducted, during which global impact forces on a model of the TERRY FOX were compared to those measured independently on the impact plate. Percent differences between the two measurement systems ranged from 6.3 to 12.1% for the sway and pitch forces, depending upon whether the impact was symmetrical or oblique. The surge force from MOTAN was about 20% less than the longitudinal force measured on the impact plate. Results showed that MOTAN is a viable means of measuring ice-induced global impact forces and, therefore, is feasible for measuring loads on ships, at full-scale, during icebreaking operations.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
