Abstract
Abstract Modern wireless systems operating in the millimetre waves bands are now to be used in complex confined media such as mining environment. System designs require that multipath, fading and diffraction effects be accounted for in a suitable model. This paper presents a new propagation prediction method that can be used in mine corridors, buildings, underground roads, galleries with rough surfaces and others complex sub‐surface installations. A method named cascade impedance method (CIM) is used in combination with the segmental statistic method (SSM) in mine tunnels having considerable wall roughness and bending forms. Two (2D)‐ and three (3D)‐dimensional profiles of the radio waves are simulated and compared with available measurements at 2.45 and 18 GHz. Copyright © 2003 John Wiley & Sons, Ltd.

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
