Abstract
A new electromagnetic technique for inspecting prestressed concrete pressure pipe enables nonintrusive inspection for even single broken prestressing wires. Prestressed concrete pressure pipe (CPP) is in widespread use throughout Canada and the United States, with a total of some 19,000 mi (30,000 km) of pipe in use in North America's major water utilities. Many of these lines are more than 50 years old, and half are expected to need repair or replacement over the next 20 years. To selectively maintain these lines and avoid costs from catastrophic pipe failures, utilities needed an inspection technique that was highly sensitive, reliable, effective, and economical. An innovative electromagnetic technique, based on the remote field eddy current (RFEC) inspection technique, has been developed that allows nonintrusive inspection of prestressed CPP. Full‐scale testing conducted on embedded cylinder pipes and bar‐wrapped pipelines demonstrated the new RFEC technique's sensitivity to both single and multiple breaks in prestressing wire.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
