Abstract

fetched live from OpenAlex

The exterior beads formed during a butt fusion process were used for non-destructive testing of the quality of butt-fused HDPE pipe joints. This innovative concept was tested using a dimensionless quality parameter that is based on tensile energy to break (TEB) values obtained from tensile testing of both the bead and joint specimens. The results show an r2 of 0·87 for a linear regression between these two sets of specimens, which supports the hypothesis that the external bead squeezed out of a butt-fused joint can be used to test the quality of the joint itself. Statistical analysis was carried out to determine the effects of other tested parameters. Furthermore, four distinct failure modes have been identified and a quality test protocol using the quality parameter is proposed.

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.
