Abstract

fetched live from OpenAlex

In this work, density graded foams were produced using linear medium density polyethylene as the matrix and different grades of Expancel microbeads. Local density inside the foams was controlled by setting independently the top and bottom plates of a compression mould at different temperatures and by controlling moulding time. Due to the temperature gradient, complex density profiles were produced and a complete morphological analysis was performed to extract average cell diameter and cell density across foam thickness. Finally, the tensile and flexural moduli are reported and discussed in relation with foam structure.

Full frame distilled prediction

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.
