Abstract

fetched live from OpenAlex

The classical and the relativistic Doppler effect for both acoustic and light waves are formulated exactly by a systematic method. This method differs only in its usage of classical and relativistic transformation laws in the formulation of the classical and relativistic Doppler effect, respectively. The method is straightforward, and much more logically rigorous than the typical demonstrations using graphical illustration. In the formulation of the classical Doppler effect, as expected, no aberration and no transverse classical Doppler effect are found. In the formulation of the relativistic Doppler effect, one important discovery is that the transverse relativistic Doppler effect depends only on the speed of the source relative to the observer, irrespective of the nonskew velocities of the source and the observer relative to the medium. PACS No.: 03.30.+p

Not 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.
