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.

Abstract

fetched live from OpenAlex

A breakthrough has been achieved in making small solar pumps affordable and easy to set up and use by small farmers in Africa. Numerous off-the-shelf pumps running on direct current were tested when connected directly to a single solar panel, without any battery or additional electronics. Of the many pump models tested, two were found to meet our criteria for low-cost solar pumping for small-scale irrigation. These pumps have been successfully operating in Cameroon, Chad, Burkina Faso, Senegal and Canada since 2014. We present information on the components, cost and performance of these pumps for small-scale irrigation.

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.
