Modified lifeboat pendulum tests at MUN
Bibliographic record
Abstract
This report describes an experiment conducted by the National Research Council Institute for Ocean Technology (NRC-IOT) at the Structures Laboratory located in the S.J. Carew Building on the Memorial University campus. The experiment was conducted in order to evaluate the performance of two acrylic panels, and the instrumentation therein, that were added to the hull of a Totally Enclosed Motor Propelled Survival Craft (TEMPSC Lifeboat). Also included in the objectives of this experiment is the calculation of variables placed in a mathematical model of the ice and hull interaction. Master's degree student Allison Kennedy is currently preparing this model. The acrylic panels were added to the lifeboat in order to measure the forces experienced by the hull of the lifeboat while passing through ice-covered waters. As such, the panels were tested using ice with an apparatus that was constructed to suspend a pendulum comprised of a rope and a specimen (sphere) of ice. The pendulum was then raised to a predetermined angle and allowed to swing in its natural arc, impacting the panel. This test was repeated for 33 separate impacts, using 9 specimens of various specified diameters. As a result of this experiment, the panels were established as being stable and the enclosed instruments were verified as accurate in their readings. The results also leave ample room for the calculation of yet unknown variables located in the mathematical model. The data to calculate these variables has not yet been analyzed, and they are therefore not yet available.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
