Abstract

fetched live from OpenAlex

This paper presents a numerical study to characterize the effect of loss of blowing agents on the thermal insulation properties of polystyrene foams. In this study, a transient cell-to-cell diffusion model is developed to predict the loss of the blowing agents. The Mie theory is used to quantify the radiative conductivity. A cubic-series-parallel approach in analogy with electric circuits is employed to acquire the thermal conductivity of the gas-polymer matrix. The effects of foam morphology and blowing agent type on the loss of blowing agents and the resulting thermal insulation properties of polystyrene foams are examined.

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.

Teacher imitation

Not 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.
