Abstract
In this paper, we consider the problem of immersion ultrasonic test when a uniform array of ultrasonic transducer is utilized. Since the sound wave propagates in water and solid with two different velocities, the imaging techniques for homogeneous materials can not be utilized. In this paper, we have used a new array spatial signature, which is derived based on distributed source modeling, in three imaging algorithms including the conventional beamforming technique, the MUSIC method, and the Capon algorithm. To show the accuracy of the proposed array spatial signature, we conducted an ultrasonic immersion test. Experimental results of the three aforementioned imaging algorithms, presented here, show the accuracy of the proposed array spatial signature.

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
