Abstract
A thermoacoustic system was designed and tested to study the thermal gradient established at the two ends of its stack. A thermoacoustic device consists of an acoustic resonator containing a working fluid, which can be air or an inert gas. The resonator is driven by an exciter such as a speaker or an electrodynamic exciter to generate a standing acoustic wave inside the resonator. A stack of thin parallel plates are installed towards one end inside the resonator. The gas parcels transfer heat from the end of the stack that is close to the pressure node to the other end of the stack, creating a temperature gradient across the two ends of the stack. The heat is pumped from a cold medium to a hot medium and the device works as a refrigerator. For the design of the system, a 15 watt, 8ω, electrodynamic type loudspeaker was used as the acoustic driver. A power amplifier was used to provide the required acoustic power to excite the working fluid inside the resonator. The optimum position of the stack obtained experimentally is in agreement with that predicted theoretically.

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
