Abstract

fetched live from OpenAlex

Using an integrated finite element simulation-optimization tool, the design of a multiple zone composite wing is studied to improve its free vibration behavior. The composite structure zones are composed of multiple layers of woven fabrics with different fiber materials and orientations. Results show that a single critical zone in the structure can be identified and used (1) to significantly improve the natural frequencies of the wing regardless of other zones, (2) to perform a frequency tuning with no significant interactions with other zones, and (3) to optimally control the wing's free vibration behavior.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
