Abstract
A novel fibre high speed photography method has been developed for solid volume fraction measurement. This system mainly includes a small fibre‐optic endoscope, a halogen light source, a high speed video recorder and a powerful computer with large memory. The endoscope which could be inserted into the reactors is used to form motion images of particles within the measurement space illuminated by the halogen lamp. The motion images of particles are recorded by the high speed video camera and will be processed by a series of digital image processing algorithms such as calibration, denoising, enhancement and binarisation. The solid volume fraction can be figured out by counting the particle number on each frame in the video. The feasibility and reliability of the measurement system have been tested in a pilot 3D spouted bed which is 200 mm in diameter and 1500 mm in height. The radial profile of the solid volume fraction in the spouted bed is determined using the analysis method mentioned above. The results indicate that the fibre high speed photography method is a promising tool for gas–solid flow research.

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 it
