Abstract

fetched live from OpenAlex

Prince of Wales’ Fort near Churchill, Manitoba, Canada, has forty 18 th century cast iron cannon set on its ramparts and exposed to the elements. Two hundred and fifty years of corrosion has removed historical detail. Although there is minimal pollution, (the neighbouring ocean has a low saline content and is frozen for much of the year), relative humidity is very high and windborne particles continually expose new material to corrosion processes. With the failure of numerous protective coating regimes, a fundamental re-examination of the problem of “preserving the cannons’ fabric for future understanding, appreciation, and study” was initiated in 1996. Since no corrosion data for grey cast iron in a sub-arctic, marine environment was available to provide a scientific basis for resource management decisions, a thirty year corrosion rate study using coupons of like alloy has been instituted. Two questions have been posed in the study: what is the corrosion rate; and how long will it take at that rate to obliterate remaining surface detail? This paper presents the corrosion rate results for the first five years of the study. Also offered for discussion will be the question: what is an “acceptable” rate of material loss for cultural resources in an uncontrolled environment where access is difficult and visitation low?

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.
