Abstract

fetched live from OpenAlex

There is a general agreement that in service conditions the quality of insulating fluids gradually deteriorates under the impact of electrical, thermal and chemical stress. Two ASTM methods are used to monitor the deterioration of liquid insulation step by step. A comparison is made between the performances of a commercial based mineral oil and ester fluids. The results obtained using a laboratory grade spectrophotometer and a ratio-turbidimeter, indicate that the absorbance increases by a significant and easily observable margin with ageing rate. Under the same aging condition, synthetic ester ages considerably slower than mineral oil; natural ester showing an intermediate behaviour.

Teacher imitation

Not 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.
