Bibliographic record
Abstract
Over the past seven years, a comprehensive interdisciplinary research program has been conducted between researchers at the University of Ottawa and at the Canadian Hydraulics Centre (CHC) of the National Research Council of Canada. The objectives of this on-going research program are to identify and quantify forces that are imposed on near-shoreline structures when exposed to tsunami- induced hydraulic bores and to investigate mitigation strategies to dampen these forces. The experimental component of this research program involves two structural models (square and circular) that are tested in the High Discharge Flume at CHC. The structural models are instrumented to record base shear force-, base overturning moment-, pressure-, acceleration-, lateral displacement- and bore depth-time histories continually during testing. Impact loading resulting from wood debris of different sizes and located at pre-determined distances from the structural models is also studied. Furthermore, this research program aims to review tsunami-induced forces on structures prescribed by recent design documents.

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.
