Modelling the lightning return-stoke current using Heidler function
Bibliographic record
Abstract
Different functions have been used to model the lightning return-stroke current with the aid of direct current measurements at tall structures. In this paper, a comparison between the Pulse function and Heilder function is carried out to determine the suitability of each of these functions for simulating the lightning return-stroke current, measured at the CN Tower. An automated system for estimating the lightning return-stroke current waveform parameters from the measured current derivative signal will be introduced. The curve fitting technique of the system, initial values and feasible regions of the function parameters will be discussed. Also, the idea of using an artificial lightning signal free of noise and reflections as a reference signal for evaluating the parameter extraction system will be presented. Finally, the lightning return-stroke current waveform parameters (peak, maximum rate of rise, risetime, pulse width, decay time and charge) are expressed in term of the Pulse or Heidler function parameters.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
