Abstract

fetched live from OpenAlex

This thesis presents an implementation of a mathematical model, Wang tilings, for the representation of metallic glasses in Molecular Dynamics. The purpose is to assess whether a Wang tiling specimen can be considered a representation of a metallic glass. The implementation of Wang tilings for the representation of amorphous structures can potentially increase system sizes and enable the study of small tile sets that achieve the same results. A technique for creating a Wang tiling specimen and a true specimen is developed. These specimens are then submitted to uniaxial tension deformation and analyzed macroscopic and microscopically. The analysis consisted of stress-strain curves, atomic bond deficiency defect concentrations and a shear banding analysis. The technique for the creation of a Wang tiling specimen was accurately developed, however, the tiled system is not a surrogate of the true specimen. This research is a first approach for implementing Wang tilings in Molecular Dynamics.

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.
