Abstract

fetched live from OpenAlex

Weirs and notches are efficient devices for measuring flow rates. Banks of slit weirs forming multislit weirs allow both precise discharge measurements in a very large range of flow rates and permit a good flow regulation. V-shaped weirs are traditionally used as precise laboratory flow measuring devices, especially in the low discharge ranges. In the current investigation, the method of images was used to form the V-shaped multislit weir system to allow measurement and regulation of flows in a large range of flows that includes very low flow rates. Experimental studies were conducted to determine the discharge coefficients of V-shaped multislit weirs over a wide range of weir Reynolds numbers. The study provided a single relation between the weir discharge coefficient and the weir Reynolds number for both the rectangular and V-shaped multislit weir systems.

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.
