Abstract

fetched live from OpenAlex

An approach to predict the sound radiation of baffled poroelastic media including fluid loading effect is discussed. The problem has been solved using a mixed finite-element method (FEM)-boundary element method (BEM) approach. In this approach the fluid loading is accounted for using an admittance matrix and solid phase-interstitial pressure coupling terms. The method has been considered in the case of an acoustic excitation. The results show that the radiation of the porous medium into the semi infinite fluid amounts to an added admittance term onto the interface interstitial pressure degrees of freedom.

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.

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.
