Abstract
In February 1998, stay cable oscillations were observed on the Cochrane Bridge, Mobile, Alabama in winds accompanied by rain. Rowan Williams Davies & Irwin Inc. (RWDI) was retained by A.G Lichtenstein & Associates to assist them in identifying the causes of the cable oscillations, to assess the potential of future wind-induced cable vibrations, and to design a damping system to mitigate the oscillations. RWDI performed on-site oscillation decay measurements for some of the stay cables. Inherent damping values for the cables were calculated from the decay traces. Using these damping values and a criterion based on Scruton number (mass damping parameter), the potential for rain/wind type oscillations for the stay cables was assessed. In addition, the cables susceptibility to other forms of wind-induced vibrations was reviewed. The program of work provided an opportunity to check the validity of criteria for wind-induced oscillations against field observations.

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
