Abstract
Dispensing has been widely used in industry to control the delivery of fluid materials. Among various dispensing approaches, positive-displacement is recognized as the most promising as its performance is assumed to depend on the mechanical motion of the dispensing apparatus and not on the properties of the fluid dispensed. However, with decreasing volumes dispensed, this assumption is no longer valid as the fluid properties, and in particular the compressibility and flow behavior, can have a significant influence on the performance of the process. This paper presents the development of a model for the positive-displacement dispensing process that accounts for both fluid compressibility and non-Newtonian flow behavior. This model is used to investigate the process performance, with the emphasis on identifying the effects of such factors as the fluid volume in syringe and the needle temperature on the consistency in process performance.

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 it
