Abstract
To mitigate the effects of dynamic tension on marine towed cable-body systems, a previously proposed Digital Twin of the cable is implemented and evaluated in this paper. The Digital Twin uses available sensor data and simulates the cable dynamics in parallel with the physical system, outputting a real-time estimate of the cable tension and towbody motion. The Digital Twin model and implementation are first summarized. Then an experimental study is performed to demonstrate and verify the ability of the Digital Twin to estimate the tension in a small-scale cable-body system. The experiment consists of cable-winch system mounted on an actuated platform over a water channel. The system is instrumented to measure the cable tension and towbody position. The Digital Twin, which takes only the platform position as an input, is shown to reliably run in real-time for a range of input motions and predict the cable tension and towbody motion with reasonable accuracy.

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
