Abstract

fetched live from OpenAlex

This paper explains a new procedure for the direct measurement of wave resistance from the measurement of ship-wave height on a patch of surface water near the hull. The optical instrumentation used and the newly developed method for numerical calculations are explained. Internal consistency tests and a comparison with well-known longitudinal wave height cut methods, LCM, are provided. This numerical procedure does not require any truncation correction and uses all of the data collected by an optical system described in the paper. This procedure could be more attractive to narrower tanks, as the requirement for tank beam to model length ratio for successful truncation correction b/L > 5 is removed. This formulation can also be used in connection with data collected by a series of wave probe records.

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.
