Abstract

fetched live from OpenAlex

The seismically vulnerable East Span of the San Francisco-Oakland Bay Bridge will be replaced with a dual east bound and west bound 3.6 km long parallel structure. The iconic single tower asymmetric self-anchored suspension bridge was selected by an international panel of experts from a total of four design alternatives that were developed for the signature main span. Analytically, geometrically, and in the design of practical details for fabrication and durability, the Self Anchored Suspension Bridge is a unique structure requiring innovative solutions and departures from conventional design. Whether a similar bridge of this scale will ever again be proposed is unknown. However, the set of methods and technologies developed to meet these challenges offer an illustrative study of designing a world class structure, an architectural icon, and a seismic innovation all at one time in one of the most seismically challenged areas in the world. The bridge will be open to traffic by the summer of 2013.

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 distilled prediction

Teacher imitation

Not 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.
