Abstract

fetched live from OpenAlex

The paper presents the obtained results and preliminary conclusions of experimental monitoring and numerical modeling of the thermal regime of railway track structure carried out on experimental stands (railway track models in 1:1). The purpose of the experimentation is to optimize the structural thickness of the protective layer in the subgrade structure. The first part of the paper describes the design of experimental stands and methodology for monitoring heat and humidity variations in the railway track structure. The second part characterizes the results of numerical modeling of the thermal regime of the railway track model using the Canadian SVHEAT SoilVision software and subsequently carried out comparison of results of experimental measurements and numerical modeling. The SoilVision system is a modeling software based on the finite element method. The paper also introduces the preliminary design nomogram for determining the structural thickness of the protective layer of subgrade surface.

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.
