Abstract

fetched live from OpenAlex

In this paper, instantaneous complex current and voltage for steady-state single-phase alternating-current (AC) circuit are introduced to improve the teaching methodology of instantaneous powers in undergraduate power courses. In contrast to the classical approach using fixed phasors, it is shown in this paper that an instantaneous solution approach also provides interesting results and leads to exact formulations of instantaneous powers. As a step towards building instantaneous reactive-power metering equipment for teaching purposes, a numerical model has been developed using Matlab/Simulink software. The evaluation of the approach by means of a student assessment is also addressed in the paper.

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.
