Abstract

fetched live from OpenAlex

Abstract The mechanical behavior of silts is significantly influenced by the soil particle fabric (i.e., spatial arrangement of individual particles) in addition to the well-known effects arising from void ratio and effective confining stress. Unlike for sandy soils, the research work conducted on the fabric of silt matrices (particle size ~2 to 74 μm) is scarce. A research program is undertaken to systematically investigate the fabric of silt particle matrices using non-destructive, X-ray micro-computed tomography (micro-CT) imaging technology. The imaging of matrices of commercially available, uniformly graded, pre-calibrated, standard size spherical silt particles (mean particle size of 50 μm) provided useful insights on the ability of micro-CT imaging to capture particle size, shape, volume, and determine scalar fabric parameters such as void ratio. The objective is to extend the work to fundamentally examine the silt particle matrices of natural silts, and in turn, support the geotechnical engineering characterization of the complex stress-strain behavior of silts.

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.
