Abstract
In January 2004, Memorial University of Newfoundland (MUN) purchased a Particle Image Velocimetry (PIV) system for making flow measurements in a towing tank. The system was innovative since the expensive laser and CCD cameras were placed in air, above the water surface and images of the seed particles were obtained by observing the underwater flow through boroscopes. This paper describes the PIV system and presents some preliminary results of flow measurements. The first set of results was obtained from experiments with a small propeller in stationary flow. The second set of results was obtained from measurements of the downstream wake of an escort tug with a yaw angle. The third set of results shows the flow measurement of vortex induced vibration for a flexible riser model.

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
