12D-5 NDE of Adhesive Joints Using V(x,t) Data
Bibliographic record
Abstract
In this paper we examine the NDE problem of the detection of bonding, verses disbonding, at the interfaces of a typical bonded plate. By using a wide angle focused transducers results are obtained in the space-time domain (V(x,t) data). This setup generates a variety of Lamb modes within the plate, provides leaky wave data spread throughout the time space domain, and eliminates the time domain overlap problems of waveforms from normal incidence testing method. Directly comparing the V(x,t) data additional leaky mode reflections are observed, where the period of these reflections if found to increase linearly with the thickness of the adhesive layer. Additionally we investigate the K-F map (V(k,f) data) generated from the 2D Fourier transform of the V(x,t) data, and briefly compare the expected theoretical results with the experimental results for both V(x,t) data, and K-F maps.

How this classification was reachedexpand
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.
