Abstract

fetched live from OpenAlex

A modified implanted Gradient Ratio (GR) test system was proposed in the study. In comparison with the conventional GR test device, all the piezometers are implanted into the soil specimen, and an additional piezometer is installed at soilgeotextile interface, in order to precisely measure the pore pressure variation of the soil-geotextile system. By using the modified GR test apparatus, 120 tests were conducted to study the clogging behavior of soil-geotextile system. Four types of needle-punched nonwoven geotextiles and five gap-graded soil mixtures were used in the program. These soils are the mixture of the Ottawa sand and various percentages of weathered mudstone. Three hydraulic gradients were used in the GR tests. The results of the study indicated that the modified implanted GR test system is able to provide pore pressure head measurement within the test specimen. In general, GR values obtained from the implanted GR test system are greater than those obtained from the conventional GR tests.

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.
