Weibull statistical analysis of area effect on the breakdown strength in polymer films
Bibliographic record
Abstract
The area and film thickness effects on the breakdown strength were examined for different polymer films at room temperature. Electrodes of four different diameters were used for this experimental work, which were in the range of 1/2 to 2 inches in diameter. Materials of various thickness used for this investigation were aramid paper (NOMEX type 410), Polyimide film (KAPTON), Mylar Polyester film, and Nomex-Polyester-Nomex composites. Two-parameter Weibull distribution has been used to analyze the results. The experimental analysis shows that the breakdown strength decreases as the electrode area increases. In case of thickness of 125 /spl mu/m film, change of 10-12% in the breakdown strength was observed, where as for 25 /spl mu/m thickness, 30-35% change in the breakdown strength was noticed. It was also noticed that the 25 /spl mu/m thickness films are more exposed to the mechanical damage during handling process, thus chances of lower breakdown strength of such films are more, as probability of covering the mechanically damaged area increases with the increase in the electrode area.

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.
