Flame Spread along a Thin Combustible Solid with Randomly Distributed Square Pores of Two Different Sizes
Bibliographic record
Abstract
The objective of our study is to predict the flame spread route by the quantity of combustible materials and their placement. In this paper, we examine non-uniform flame spread in open air along a thin combustible solid with randomly distributed square pores of two different sizes (8 x 8 and 4 x 4 mm respectively). Experimental results show that the flame-spread probability falls with increasing porosity. Despite uniform porosity, the flame-spread probability differs with the rate of large square pores to small square pores. For a combustible area larger than a noncombustible area, the flame-spread probability reaches the local minimum value with a change in R8 (ratio of 8 mm pores) under the same porosity condition. Conversely, for a combustible area smaller than a noncombustible area, the flame-spread probability reaches a local peak with changing R8 under the same porosity condition. In addition, we calculated the ratio of the unburned area (unburned area / total combustible area) by counting the unburned cells after the flame spread test, which might be useful to predict the fire hazard. We found that the ratio of unburned area grows with increasing porosity.

Full frame distilled prediction
Teacher imitationNot 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.
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 teacher head, not a consensus.
