Abstract
Investigation carried out on design and fabrication of tonpilz sandwich transducerof frequency around 18 kHz for underwater acoustic command applications are presented. Design criterion based on lumped parameter equivalent circuit and constructional details of the transducer are discussed. Electro-acoustical efficiency is evaluated from motional admittance measurement. Frequency response of the transmitting and receiving sensitivities as well as the directional response are reported. The transducer is observed to show a good transmitting peak response (149.5 dB re 1 μPa/V at 1m), good receiving peak sensitivity (-161 dB re iV/μPa) wide bandwidth (6 kHz) alongwith nearly omnidirectional response. Frequency at which peak transmitting response is observed deviates about 10% from the design frequency.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; the direct Gemma label and the distilled Codex classifier agree on what is shown here.
