Abstract
Terminal velocity and drag coefficient of wheat kernel and straw materials (Canadian variety) have been experimentally measured by suspending the particles in an air stream. The effects of mass and moisture content of wheat kernel, node position and length of straw on terminal velocity were studied. The results showed that mass and moisture content have significant effects (p<0.01) on terminal velocity. By increasing mass of the kernel from 0.02 to 0.05 g and moisture content from 7 to 20 %(w.b.), its terminal velocity increased linearly from 7.04 to 7.74 m/s and 6.81 to 8.63 m/s, respectively. Drag coefficient of the wheat sample (0,96) showed this kernel was similar to a cylinder in an air stream. The terminal velocity of the straws with different node positions (node free, end node, and central node) and lengths (1 to 10 cm) were measured from 2.53 to 4.85 m/s. Terminal velocity increased by increasing length from 1 to 2 cm and decreased by increasing length from 2 to 10 cm. The results showed that terminal velocity and drag coefficient of wheat straw depended on node position and the end node position had the highest terminal velocity and the lowest resistant coefficient. For air separation of Canadian wheat and straw, the air flow should be less than 7.04 m/s and more than 4.85 m/s.

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
