RESEARCH ON USING PLYWOOD MADE FROM DOMESTIC SPECIES OF WOOD FOR LONGBOARD MANUFACTURING
Bibliographic record
Abstract
The paper presents the results of the experimental research on replacing the actual plywood generally used for longboards manufacturing with plywood made from domestic species of wood, namely beech and birch wood. The research is focused on the determination of bending deformation, modulus of rupture (MOR) and modulus of elasticity (MOE) for bending strength of the investigated plywood specimens according to SR EN 310-1996, and also of the longboards made from the three types of plywood. The research was conducted on standard specimens made from beech and birch plywood on one hand, and on specimens made from a combination of bamboo and Canadian maple plywood, on the other hand, having the sizes and testing position according to SR EN 310-1996. In addition, boards having sizes and shapes of actual longboards were also tested for bending deformation, using in all cases a constant distance of 500mm between supports when applying the force, equals to the distance between track rollers of longboard. The conclusion of the research is that the domestic plywood made from beech and birch wood could replace in the future the actual plywood used in the longboard manufacturing

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
