Abstract

fetched live from OpenAlex

Debarking process is a very important step for many industrial uses of wood. The ring debarker commonly used in sawmills. The variations of the log physical properties, environmental and storage conditions, and debarking operation strongly influence the bark remaining, wood loss and damage percentages on debarked log. In this paper a MPC based ring debarking optimization system is presented. In this system the log dimension before debarking and bark remaining and wood loss or damage after debarking have been online measured. A mathematical model has been developed to simulate the ring debarking process, which is also used by an optimizer to define the debarking setpoints. An online identification has been also developed to adjust the model parameters according to the errors between model prediction and online debarked log quality measured. Some simulation results proved that the optimization system can ensure debarked log quality by adjusting debarking operation parameters according to each log fed to debarker.

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.
