Abstract

fetched live from OpenAlex

The development of reliable lifecycle intervention plans for water distribution systems depends on better understanding of water main degradation behavior. Traditionally, water main failures have been studied as Weibull/Exponential processes. This paper investigates the application of log-linear model for assessing metallic water main structural degradation. A comparison of the proposed model with the existing Weibull/Exponential based model is presented. Water mains inventory, operational and performance data from a Canadian municipality are used in the analyses. Conclusions concerning the adequacy of existing models and the applicability of proposed models are made. Municipalities and water utilities can use the method provided herein as a tool for desktop condition assessment and risk based failure analysis.

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.
