Abstract

fetched live from OpenAlex

In sinusoidal situations, power factor definition is unique and expressive. However in nonsinusoidal situations and/or nonlinear load different power factors are proposed to express these situations. In this paper a new fuzzy based representative quality power factor is introduced to represent these power factors. The proposed representative quality power factor (RQPF) was applied to different cases, linear, nonlinear, sinusoidal, nonsinusoidal considering lagging and leading power factor. It is shown that the new RQPF is expressive and accurately represents the existing power factors in all cases and in all situations. Taking into consideration the advantages of the fuzzy systems such as simplicity, ease of application, flexibility, speed and ability to deal with imprecision and uncertainties, this factor can be useful for power quality evaluation, cost-effective analysis of PQ mitigation techniques, as well as billing purposes, in these situations.

Not 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.
