The methane number has a strong impact on the anti-knocking behavior of the fuel gas. A membrane separator equipped with elastomeric membranes separates the higher hydrocarbons from the associated gas. In dependence of the gas source and the ambient temperature the methane number of the gas fluctuates. A methane number higher than 50 was required to ensure a smooth operation of the Otto carburetor engine. Operating experiences with the pilot unit will be discussed as well as membrane data and design criteria for a commercial plant.

How this classification was reachedexpand
Full frame machine prediction
Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
