Peak Ice Loads on a Lifeboat in Pack Ice Conditions
Bibliographic record
Abstract
Abstract Field testing of a modified Totally Enclosed Motor Propelled Survival Craft (TEMPSC) was conducted in March 2013 in managed level ice conditions. This testing was part of a multi-year trials program, conducted by the National Research Council (NRC), which aims to investigate design considerations for a conventional TEMPSC operating in ice. During the March 2013 testing campaign, the TEMPSC was equipped with a side impact panel and bow visor, both instrumented with load cells to measure local ice impact forces. The resulting local ice load measurements taken during this field trials campaign are presented and the operational performance is discussed. This was the first year during the trials campaign in which local loads on the stem were measured and recorded. The results of this set of field trials could be useful to support the implementation of new TEMPSC design considerations to allow for better performance in harsh, northern conditions. It could also provide operational insight to promote more effective and low stress navigation through ice conditions.

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.
