Abstract

fetched live from OpenAlex

In this study. a novel experimental method that was previously developed was used to directly measure the internal diffusion (D) and the equilibrium partition coefficients (ke for three classes of volatile organic compound (VOC), (1) aliphatic hydrocarbons, (2) aromatic hydrocarbons, and (3) aliphatic aldehydes, through typical dry building materials (plywood, particleboard, vinyl floor tile, gypsum board, subfloor tile, and OSB). For each chemical class, correlationsbetween D and the VOC molecular weight and between ke and the vapor pressure of VOCs were developed for every product. These correlations can be used to estimate D and ke whendirect measurement data are not available and, thus, facilitate the prediction of VOC emissions from the building materials using mass transfer theory. It was found that the values of diffusioncoefficients for a given material are inversely proportional to the molecular weights of the VOCs, and the values of the partition coefficients are also inversely proportional to the vapor pressures of the VOCs. The measured diffusion and partition coefficients are useful for predicting the emission rates of VOCs from building materials.

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.
