Abstract
Transmission line theory in electromagnetics comes alive when the travelling waves are animated on a computer screen, using program "BOUNCE". Fundamental concepts such as "travelling wave", "reflected wave", and "load matching" are forcefully demonstrated in the classroom. Problems using series connections of dissimilar line, shunt loads and branches can be readily examined. Transmission line theory is applied to problems in the design of tri-state logic circuits that cannot be solved readily by hand, using animation to show how the voltage waveforms arise. Animation is used with a sinusoidal generator to illustrate the evolution to the sinusoidal steady state, as an introduction to solving transmission line circuits with phasors. Students are encouraged to run BOUNCE at home as a computational laboratory to verify their solutions to homework problems. This paper presents the BOUNCE program, and some of the demonstrations with BOUNCE that are used in the classroom.

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
