Radiation by a submerged cylindrical shell in response to an external non-stationary acoustic pulse
Bibliographic record
Abstract
A mixed analytical-numerical solution has been developed, where the separation of variables was used in combination with the Laplace transform technique to obtain the diffraction and radiation pressure in modal form, and the finite differences were employed to obtain the harmonics of the shell surface displacements, with subsequent coupling of the two parts. A steel shell submerged into water was considered, and its thickness and radius were assumed to be 0.005 m and 0.5 m. The fluid is assumed to be irrotational, inviscid, and linearly compressible, and is therefore governed by the wave equation. The motion of the fluid is coupled to that of the shell through the dynamic boundary condition on the interface. The images of the radiated field taken during the late interaction allow one to see the entire evolution of the dynamics of the process in a single shot, which makes them a very useful analysis tool.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
