Depolarization currents in corona charged aromatic polyamides
Bibliographic record
Abstract
An analysis is made of thermally stimulated depolarization (TSD) currents in aromatic polyamide (NOMEX), which is a high temperature material. Studies were carried out with films of 75 mu m and 127 mu m thickness, charged using a corona discharge in a point-plane gap in air at atmospheric pressure. TSD currents were measured over a temperature range of 0-200 degrees C, and the influence of various poling conditions on the TSD currents has been investigated. The effect of vacuum deposited aluminum as electrode material has been investigated. Corona charged aromatic polyamides with positive polarity voltages show TSD current of either polarity depending upon the temperature range. The activation energy for aluminum electrodes was observed to be 0.5 eV. The TSD currents for the low temperature peak are considered to be electronic. The abnormal TSD currents observed at lower temperatures are also considered to be due to negative charge carriers.>

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
