Abstract

fetched live from OpenAlex

Multiple corrosion defects are present on pipelines and frequently interact with each other. The M–E interactions occur not only at specific defects but also at the adjacency between the corrosion defects, further affecting the pipeline fitness-for-service (FFS) and failure pressure. Therefore, Level III defect assessment by integrating the M–E interaction should include mutual interaction between adjacent corrosion defects in consideration. This chapter imparts Level III assessment on multiple corrosion defects with the consideration of M–E interaction at the defects and their interaction. The defects are oriented on pipelines longitudinally, circumferentially, or overlapped, for which new interaction rules are developed for more accurate assessment of the maximum stress concentration and the associated anodic current density (i.e., corrosion rate). Moreover, the corrosion defects which are oriented irregularly on pipelines are also modeled to determine the M–E interaction and its effect on pipeline failure, while the mutual interaction between the defects is considered in modeling.

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.
