Abstract

fetched live from OpenAlex

A series of laboratory experiments was performed to investigate the hydraulic performance of stormwater inlets. The results indicate that at the transition regime and for the maximum street slope, the addition of the second inlet increased the inlet discharge by 52% and 72% for cross-slopes of 2% and 4%, respectively. The normalized inlet discharge decreased non-linearly with the approaching water head in the weir flow regime while it linearly increased in the orifice flow regime. The effect of street slope was more pronounced in the orifice flow regime and prediction models were proposed to estimate inlet discharge for different road grades and cross-slopes. The boundary between weir and orifice flow regimes was identified for each stormwater inlet design and it was found that the cross-slope shifted the boundary more towards the orifice flow regime. It was observed that the peak efficiency decreased with increasing road grade.

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.
