Abstract

fetched live from OpenAlex

PDM control and passive filtering are combined to improve, to a significant degree and at lower costs, the power factor of an AC/AC power converter consisting of a single-phase diode bridge rectifier and a series inverter without the smoothing filter of the DC voltage. A low-pass filter absorbs the harmonics of the rectifier input current, whereas PDM control, applied to the inverter, reduces the size of it filters. An optimization routine is used to solve for the position of the pulses or equivalently the holes in the PDM pattern to cancel low order harmonics. The size of the filter decreases with an Increasing number of holes created by PDM control in the current drawn by the converter. Simulation results validate the theoretical results.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
