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

The Site C Clean Energy Project is a new, 1,100 MW hydroelectric generating station on the Peace River in northeastern British Columbia, Canada. Seismic isolation has been adopted to protect more than 150 pieces of spillway gate control equipment deemed critical for dam safety and to meet the project’s operational requirements. Three-dimensional seismic isolation platforms are being used to provide operation level protection of critical electrical and electronic control equipment, with a total of 39 isolation platforms used throughout the spillway headworks structure. Shake table testing of two 3-D seismic isolation platforms and 12 pieces of equipment was conducted following the framework of IEEE 693-2018, Annex W. The paper will describe the design and testing of the 3-D isolation systems and equipment being implemented on the project and key aspects of their benefits and effectiveness.

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.
