Abstract

fetched live from OpenAlex

In this paper, an artificial neural network that considers the system as a black box is designed for the mass transfer modeling of supercritical ethane extraction. In addition, a hybrid model using both neural network and Peng-Robinson state equation is developed for supercritical ethane extraction, where the neural network is used to generate the nonlinear binary interaction parameter of the Peng-Robinson state equation. The predictions of the proposed neural network models are compared to a conventional model with a Peng-Robinson equation of state in literature. Generally, the results using the proposed models are better than those using the conventional model.

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.
