Abstract

fetched live from OpenAlex

In nonsinusoidal situations, power components definitions contained in the IEEE standard 1459-2000 are based on a frequency-domain approach using Fourier transform (FT). The frequency-domain approach can provide amplitude-frequency spectrum while loosing time-related information. Moreover, the FT carries a heavier computational burden. To overcome these limitations, definitions of power components are reformulated in the wavelet domain using the discrete wavelet transform (DWT). Using the DWT preserves the information concerning time and frequency and also reduces the computational time and effort by dividing the frequency spectrum into bands or levels. The results of applying the reformulated definitions show that the problem of spectral leakage between wavelet levels can be minimized by suitably choosing the wavelet family along with suitable mother wavelet. The reformulated definitions could be useful for setting tariff and evaluating the quality of the electric energy supply especially when considering nonstationary waveforms where the Fourier transform-based power components definitions fail.

Full frame distilled prediction

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.
