Abstract
For pt.I, see ibid., no.3, p.015-021 (2003). The finite element procedure proposed in part I was successfully used to model a smart-self-damage control system consisted of SMA wires embedded in a polymeric matrix. A parametric study was performed to investigate the effect of various parameters on the performance of the system. It was found that increasing current density speeds up the recovery process although it adds more heat to the system. Also, it was found that increasing wire diameters although speeds up the recovery process as well, it might cause harmful effects to the system by increasing the difference in CTE forces effect. Increasing number of activated wires was found to be beneficial as it reduces the amount of phase transformation and forces required per wire, and increases system sensitivity to small cracks. It is suggested that convection coefficient not to be too low or to high, and the initial temperature of the system to be as close to the Austenite start temperature as possible. It was also found that SMA wires prestraining have negligible effects if its not too low.

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
