Abstract

fetched live from OpenAlex

The County of Essex is responsible for the maintenance and construction of 87 bridges. As many freeze-thaw cycles are experienced in our area, Essex County highway bridges are prone to black ice and must be salted on a priority basis for the safety of motorists. However, the long-term effects of this established practice have become obvious. Our wetlands and farmlands are being damaged and our highway bridges require costly deck replacements. A geothermal snow melting or de-icing system is an environmentally-friendly alternative to the common mechanical and/or chemical winter maintenance and is available day and night without a costly stand-by emergency response. A bridge structure which crosses the North Branch of the Cedar Creek within a provincially significant wetland provided an opportunity to be a testing facility to determine the feasibility of utilizing geothermal energy and to assist with the design of other renewable energy systems. The County of Essex used the opportunity provided by the reconstruction of this environmentally-sensitive to pro-actively implement a prototype into the bridge deck. This project was nominated for the TAC 2008 Environmental Achievement Award.

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.
