Abstract

fetched live from OpenAlex

The railway freight car has not onhy safety stability of high-speed operation but also good capacity of curve negotitation.Based on the data of dynamic performance test of freight car with K2,K4,K5 amp;K6 type bogie and run-in test of Z8A type bogie negotiating sharp curve,this paper analyzes the dynanic performance of freight car negotiating sharp curve and turnout branch,and makes comparative analysis on sharp curve negotiation capability of the differeat type bogies.The influence factors of sharp curve negotiation are also discussed in this paper,and the condusions and recommendations are given in the end.

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.
