Abstract

fetched live from OpenAlex

Cette étude est consacrée à l’utilisation de la technique d’émission acoustique pour la détection d’endommagements au sein de réservoirs composites de gaz naturel pour véhicules (GNV). Des essais de mise sous pression interne avec suivi de l’émission acoustique ont été menés sur des réservoirs de GNV de type 3 (selon ISO11439 et ECER110), constitués d’un liner aluminium renforcé et totalement recouvert par un bobinage composite à fibres de carbone. Les tests ont été réalisés sur des réservoirs soumis à un impact balistique à différentes énergies, sur des réservoirs soumis à des essais de chute suivant différentes hauteurs et sur des réservoirs avec entailles longitudinales et transversales de différentes profondeurs. Les résultats de ces essais avec suivi de l’émission acoustique sont discutés en fonction du type et de la sévérité des endommagements.

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.
