Abstract

fetched live from OpenAlex

Vegetable oils have excellent dielectric properties and high thermal characteristics (flash point and fire point). However, their general acceptability is questionable due to the poor viscosity profile at low temperatures and oxidation stability. Thus, enhancement of the oxidation stability and flow properties of canola oil-based dielectric liquid stands as the main goal of the present study. Methyl ester synthesized from palm kernel oil was mixed with a commercially available canola-based insulating liquid in 25%, 50%, and 75% concentrations. The behavior of all samples was monitored during accelerated thermal aging in the presence of oxygen for different periods. Specifically, observations were made for fresh samples under ambient temperature and 12, 24, 36, and 48 hours at $110^{\circ}\mathrm{C}$. Acidity, moisture, and dissolved decay particles were used as a factor for monitoring the rate of degradation. It was observed that the mixture with a high percentage of methyl ester (C and D) shows stability to oxidation. This experimental investigation shows that a mixture of oil with saturated and unsaturated fatty acids has promising thermo-oxidation stability properties.

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.
