Abstract

fetched live from OpenAlex

On confectionne des pièces que l'on appellera tampons, sur lesquels on exécutera des fentes selon diverses configurations comme il sera indiqué plus loin. Ces fentes permettront l'évacuation de l'écoulement de l'air et seront appelées tout au long de cet article "canaux d'évacuations". On mesure la vitesse d’écoulement d’air à la sortie du canal d'évacuation à l’aide d’un anémomètre à fil chaud de type DISA 55M et on mesure également la pression en paroi le long du canal. Les paramètres d’influence sont le retrait δo de la buse de soufflage vis-à-vis de la surface frontale du tampon, la distance δ de ce dernier vis-à-vis de la surface de la paroi à mesurer et la profondeur Pr du canal. La buse utilisée sera celle classique à surface frontale plane désignée industriellement par « buse N°02 ». La largeur L des canaux d’évacuation est 1.5 mm.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
