Abstract

fetched live from OpenAlex

Wood mills have used bandsaw blades for the primary breakdown of timber into lumber for centuries. By reducing the width of the saw cutting edge, material waste can be reduced. Thin-kerf saw blades are susceptible to lateral forces during cutting. To combat this behavior, saw lers introduce residual stresses into the blades. Classical methods for monitoring saw blade tension, such as the light-gap method, are subjective and analog. There exists a necessity to monitor the amount of residual stress induced into the blades reliably, using a nondestructive test. A newly proposed method for stress evaluation, incremental shearography, o ers the advantage of measuring transverse plate bending behavior at micron resolution. Shearography, a direct measure of surface slope, promises a robust, full- eld measurement using low-cost components. By comparing measured slopes to those analytically found, a stress resultant of the tensioning process can be inferred.

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.
