Abstract
There is a need to reduce the inspection time of drains in dams done through video camera.A method based on acoustic guided wave propagation was developed.A system of loudspeaker and microphone was designed to send and receive at the mouth of drains acoustic waves.Physical models were developed to describe wave attenuation as it propagates and its reflection and transmission through consecutive obstructions.Extensive lab tests were undertaken in 3inch composite and 4inch fibro-cement pipes to evaluate the performances of these models.Wave attenuation coefficient and superposition factor for the recorded reflections were obtained for these two types of pipes.The effects of different pipe conditions were evaluated, such as: distinct and close proximity obstructions, cavity and pipe outlet.Tests were undertaken on actual drains of dams.

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
