Abstract
Measured and predicted temperatures in a grain processing building under heat treatment -1.Temperature profiles during heat treatment.Canadian Biosystems Engineering/Le génie des biosystèmes au Canada 54: 3.1-3.8.Heat treatment is an effective method of controlling pest insects in grain processing facilities.Temperatures inside a heat-treated flour-storage building and temperatures of wheat, oats, wheat flour, and oat flour in piles or tubes, 0.15 m high, on a concrete floor inside the building, were measured during a 20-h time period of heat treatment.The room temperature at different locations had the same distribution pattern in the vertical direction despite the presence of circulating fans at different locations of the room.Temperature gradients in the vertical direction decreased with increasing height.The maximum and mean temperature gradients above the surface of the concrete floor, in the absence of grain, were 5.4°C/cm and 3.6±0.0°C/cm;respectively.The room temperatures at higher locations varied less than those at lower locations.Moreover, after the surface grain temperature reached 97% of its maximum temperature, it was influenced by the local temperature and periphery configuration.Key words: Heat treatment, grain-processing building, temperature.Le traitement thermique est une méthode efficace de lutte contre les insectes ravageurs dans les installations de transformation des céréales.Pendant un traitement thermique dans un entrepôt de farine, nous avons mesuré les températures ambiantes ainsi que celles du blé, de l'avoine, de farine de blé et de farine d'avoine, soit en tas ou en tubes de 0,15 m de hauteur, sur un plancher de béton à l'intérieur de l'entrepôt tout au long des 20 heures du traitement.Les températures ambiantes à divers endroits avaient la même distribution dans le sens vertical, malgré la présence de ventilateurs à différents endroits de la salle.Les gradients de température dans la direction verticale ont diminué avec la hauteur.Le maximum et la moyenne des gradients de température au-dessus de la surface du plancher de béton, sans grain, étaient de 5,4 °C / cm et 3,6 ± 0,0 °C / cm; respectivement.Les températures ambiantes aux endroits les plus élevés variaient moins que celles aux endroits moins élevés.De plus, après que la température du grain de surface ait atteint 97 % de sa température maximale, elle a été influencée par la température locale et la configuration périphérique.Mots clés:

Full frame machine prediction
Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
