Abstract

fetched live from OpenAlex

Municipal waste is another non-textbook material, generally highly fibrous, heterogeneous, erratic, highly compressible, and displaying significant long-term settlement caused by plastic creep and decomposition. On the basis of the review of a number of case records, neither undisturbed sampling nor field testing is practical. On the other hand, since displacement is often the critical issue and since displacements are measurable in situ, it would seem that the use of a remote sensing system of direct measurements should be adopted where such displacements are critical. Sampling of strongly decomposed waste may be problematic because of caving problems. Conventional laboratory testing methods cannot generally be used, because the structure of the waste in the field is really indeterminate, and cannot therefore be reliably duplicated in the laboratory. Also, the pronounced fibrosity of the samples renders conventional testing of dubious value, generally yielding misleading results. Another important consideration is the fact that waste is subject to decomposition and that the stipulation of constant strength parameters like cohesion and friction is therefore not valid. This consideration appears to be largely disregarded by the profession.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
