Abstract
While certain progress has been achieved in the development of different techniques for residual stress measurement, a considerable effort is still required to develop efficient and cost-effective methods of residual stress measurement and analysis. A new ultrasonic computerized complex UltraMARS was developed recently that can be used for non-destructive measurement of applied and residual stresses in laboratory samples and real parts and structural elements in many applications for a wide range of materials. The system was used in measurements of residual stresses in the rim of a railway wheel that was in service without intensive drag braking. The measurements showed that depth of compressive hoop stresses is 26mm from the rolling surface with a maximum value of -60 MPa. Similar measurements of residual stresses in the rim of railway wheel with intensive drag braking showed that the hoop residual stresses in rolling surface layers are tensile.

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
