Abstract

fetched live from OpenAlex

The relationship between the morphology and the mechanical properties of polyethylene (PE) foams has been studied. Experiments have been made on closed cell low density foams at low testing speed as well as in impact conditions. A careful characterization of the cell size distribution and anisotropy was performed and related to the foams mechanical response. The results indicate that the mechanical response of the foams is anisotropic and can be expressed as a function of the foam morphology, using a unique morphological parameter taking into account the cell size in the appropriate direction and foam density. Previously developed for polystyrene foams, the use of this parameter is thus successfully extended to PE-based foams.

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.
