Abstract

fetched live from OpenAlex

Rail side wear on curves poses a major problem for railways. A high rate of wear directly affects the economic performance of a railway. Uneven rail side wear on curves leads to a reduction in the service life of the rail. This article looks at the results obtained from simulations carried out by means of the NUCARS dynamic curving model which yielded that at some velocities the degree of angle-of-attack and lateral force, as well as bogie design and type of wheel tread profile affect the rate of uneven rail wear. The study was carried out at the Centre for Surface Transportation Technology of the National Research Council of Canada.

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.

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.
