Abstract

fetched live from OpenAlex

A computer-based decision making tool used to minimize the cost of coating maintenance for steel bridges is presented. Variations of the model, adapted for specific usage, are presented. A maintenance approach with the lowest equivalent uniform annual cost is recommended for each analysis using the model. The analysis may be performed for a single bridge structure using deterministic or probabilistic input values, or for many bridge structures of a certain inventory using deterministic input values. Using the model to analyze the entire bridge inventory provides an estimation of the annual budgetary requirements for the coating maintenance in a region and will facilitate the prioritization of these coating maintenance projects. The paper focuses on state-of-theart practices in corrosion protection coating maintenance in the Province of British Columbia, 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.

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.
