Abstract

fetched live from OpenAlex

Maritime operations occur in a rapidly changing and extremely dangerous environment. To improve handling of cargo while at sea, this thesis develops a method for combining active-heave compensation and anti-pendulum control for a combined world-frame compensation system. State estimation algorithms are applied using low-cost inertial sensors attached to the deck of the ship and to the body of the load. fixed set-point tracking tests and simulations with sinusoidal base excitation derived from the natural frequency of the pendulum w n = g/l p (Test 084-088 and 092-096; Simulation 084-1/2-088-1/2 and 092-1/2-096-1/2). The experimental results are summarized by the mean of all repetitions with error bars to indicate the standard errors, and the results are grouped by the corresponding motion profile. . . . . . . . 7.24 World position tracking data for variable set-point tests. . . . . . . . 7.25 Relative ellipsoid volume, distance travelled, and set-point tracking RMSE for variable set-point tracking tests and simulations with base excitation derived from scaled ship motion (Test 097-104; Simulation 097-1/2-104-1/2). The experimental results are summarized by the mean of all repetitions with error bars to indicate the standard errors, and the results are grouped by the corresponding ship motion profile.

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.
