Why this work is in the frame

A frame that forgets how it found something cannot be audited. These are the routes that admitted this work.

aboutThe title or abstract carries a Canadian signal from the geographic lexicon.
no affNo Canadian affiliation: this work is invisible to an affiliation-only frame.
No Canadian affiliation. An affiliation-only frame, the usual design, would never have seen this work. It is one of the works that make the case for inverting the frame.

Abstract

fetched live from OpenAlex

Current timber trusses are mainly made using steel fasteners, nail plates, or dowels with slotted plates. Glued timber trusses are applied commercially by two companies: German PERI produces trussed joists for concrete casting and Canadian Barret Structural makes trussed joists for residential floors. These trusses are based on finger joints made using a cursor. Recently, a Finnish company Teeri-Kolmio Oy started manufacturing glued trusses for residential floors with the joint processed using a saw blade. The such joint enables deep chord routings up to through the chord, long fingers, large web-chord glue areas, minimal timber splitting, and high resistance and reliability. There are further special characteristics. Top chord support is possible without hangers. The truss can be manufactured as a long billet, stored at lumberyards, and cut for actual needs. The truss can be manufactured without open routings and water pockets. The truss is strong and reliable and can be applied for the roofs of commercial buildings up to about 30 m spans. Our study shows that the trussed roof is more cost-effective than the glulam roof which opens a promising new business possibility.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
