Simulation of an underwater glider
Bibliographic record
Abstract
Underwater gliders are being proposed as an alternative to the resource intensive and costly shipboard methods of oceanographic data collection. One such underwater vehicle currently in operation is the SLOCUM Glider. The purpose of the present work is to devise a dynamic simulation for the SLOCUM Glider that allows the vehicle's motion to be predicted in response to control inputs. Such a simulation could be used to test operational scenarios and to aid in vehicle design. The simulation developed here relies on a component buildup method in which the hydrodynamics of the vehicle components (hull, wings, vertical fin) are estimated and summed. The simulation was validated against available experimental data. The agreement was reasonable, though it was determined that more precise information on the real vehicle was needed before further evaluations could be made. It was found that very small displacements of the vehicle C.G. had a substantial impact on the ensuing motion, and that the vehicle exhibited very stable behavior. Lateral oscillations observed in the real vehicle motion were attributed to an unmodeled interaction between the vehicle and its control system.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
