Abstract

fetched live from OpenAlex

Dans les régions froides où la surface de l‘eau d‘une rivière ou d‘un lac gèle en hiver, les barrages en béton peuvent être soumis à une charge de pression exercée par la couche de glace. Cette charge de pression peut constituer une grande partie de la charge horizontale totale agissant sur un petit barrage. Du point de vue de la sécurité du barrage, il est important de déterminer la valeur de conception de la charge de glace. En février 2016, un prototype de panneau de chargement de glace a été installé sur un barrage en béton suédois. Le panneau de 1x3 m 2 mesure la pression de la glace avec trois capteurs de charge. Dans cet article, la charge de glace mesurée sur le barrage suédois est prédite à partir d‘un modèle empirique canadien, élaboré précédemment à partir d‘un programme expérimental de 9 ans dont le but était d’estimer les charges de glace causées par les effets thermiques et la variation du niveau de l‘eau. Les prévisions du modèle n’ont pas pu prédire avec précision les charges de glace mesurées. Les connaissances actuelles sur les charges de glace étant limitées, il est impossible de déterminer si les résultats expérimentaux, le modèle ou les deux sont inexacts.

Not 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.
