Abstract

fetched live from OpenAlex

Abstract This study investigated the usefulness of measurements from an agitator torque sensor in monitoring the dynamics of suspension polymerization. The main focus was to estimate the viscosity of the reaction mass during polymerization using the agitator torque as a secondary variable. Viscosity is a crucial parameter that plays a vital role in determining the efficiency of the process and the quality of the final product. Accurate viscosity monitoring is essential as it provides valuable insights into the progression of the polymerization process and its dynamic behaviour. This study developed a combined Kalman filter (KF) and fuzzy logic (FL) model to estimate viscosity in real time, addressing the challenges of noise in torque measurements. Experimental validation showed that the KF‐fuzzy model improved the accuracy and stability of viscosity predictions, particularly during the critical stages of polymerization. This approach enables better monitoring of reaction dynamics, thereby supporting process optimization and control.

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.
