Underwater power cable approximation models for offshore applications
Bibliographic record
Abstract
This work deals with modeling underwater power cables based on the ubiquitous two-port network theory applied to the distributed parameter representation of transmission links leading to the so-called exact lumped parameter line model. It is found for single-core underwater power cables with copper armor that a nominal pi model is accurate for lengths up to 25 km, two cascaded nominal pi models are accurate for up to 50 km, and a modified cascaded nominal pi model is accurate up to 100km. For single-core underwater power cables with steel armor, a nominal pi model is accurate for lengths up to 10 km, two cascaded nominal pi models are accurate for up to 30 km, and a modified cascaded nominal pi model is accurate up to 40km. For three-core underwater power cables, a nominal pi model is accurate for lengths up to 40 km, two cascaded nominal pi models are accurate for up to 75 km, and a modified cascaded nominal pi model is accurate up to 125 km.

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.
