Abstract

fetched live from OpenAlex

An integral part of a new engine certification process is the test verification of satisfactory operation in icing conditions. Icing conditions for this test, which is often conducted at sea level, need to meet or exceed conditions that would be experienced within the flight envelope. In order to assure this fact, manufacturers use analytical tools to conduct a critical point evaluation of engine over the range of flight operation for purposes of comparison to sea level testing. The recent concern for operating in ice crystals places new requirements on icing codes within the industry. One such code is used herein to describe these requirements and to illustrate the critical point evaluation procedure.

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.
