Abstract

fetched live from OpenAlex

The IEEE Standard 1366-2003-2.5 Beta Methodology was developed with the intent of providing a reasonable way to define a major event day with respect to distribution reliability performance. According to this methodology, it is valid only if a utility's reliability data completely follows the log-normal distribution, particularly with respect to the tails. This letter's desire is to show that this is not the case for data sets provided by 12 utilities and may not be the case with other utilities. Problems arise when the right tail of utility data sets do not fit the log-normal distribution. The threshold defined by the IEEE 1366-2003-2.5 Beta Methodology will vary since it is dependent on a utility's reliability data from the previous five years. As a result, catastrophic events, reflected by a large daily SAIDI value, will cause an unsuitable increase in the threshold for future years.

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.

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.
