3 decades of scientific advancement to the North American roofing community
Bibliographic record
Abstract
Three decades ago, members of the roofing community met at the National Research Council of Canada and formed a group with a common focus on evaluating roofing systems in a dynamic environment. As a result, the Special Interest Group on Dynamic Evaluation of Roofing Systems (SIGDERS) was created. SIGDERS’ operation is one of its kind in the world, with the legacy of a long-lasting research and development consortia. In this session, the impacts of SIGDERS on the industry will be discussed, including advancements in the areas of static vs. dynamic roof evaluations, diagnoses of the weakest link, significance of the roof edge, and field vs. code specification.
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.

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.
