Abstract

fetched live from OpenAlex

Abstract: An experimental technique to determine the intrinsic kinetics of gas hydrate decomposition is presented and a new mathematical model is developed. The experimental technique uses an on‐line particle size analyzer. The new mathematical model accounts for the distribution of particle sizes in the hydrate phase when determining the intrinsic rate constant of decomposition. Results from an experiment for the decomposition of ethane gas hydrates are presented.

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.
