Spontaneous fluctuations in free-molecular flow: theory, simulations, and preliminary experiments
Bibliographic record
Abstract
This thesis extends principles from past analyses of innate fluctuations in electrical circuits to the study of a simple class of free-molecular fluidic systems on the basis of an apparent analogy.This is primarily done through a derivation that draws from past electrical work to propose a measure of the limiting noise that exists in gas flow across pores when particle-particle collisions are assumed to be negligible.The results obtained from theory are then reiterated with the use of a basic Monte Carlo program that has been rigged to simulate a fluctuating average flow signal, thus permitting the estimation of a simulated mass-flow noise power in addition to transmission probabilities for a variety of pore geometries.The beginning of an experimental investigation seeking to confirm the mass-flow fluctuations expected from theory and simulation is also documented.Although no definitive conclusions in this respect are made, the experimental setup is characterized in various respects and some possible directions for future work are briefly discussed.iii the handling of gas flow in our measurement system.Specifically, the past works of graduate

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.
