Abstract
Various piezoelectric, elastic and dielectric constants of typical soft and hard lead zirconate titanate (PZT) ceramics have been determined as a function of applied AC field, DC bias field, pre-stress, temperature and frequency. Our results show significant non-linear effects and many of the effects are caused by extrinsic, or domain related effects. These effects include stress or field induced clamping and unclamping (de-ageing) of domain walls. The time dependence of the piezoelectric response has also been studied and our results provide evidence of thermally activated domain switching in piezoelectric ceramics. The use of Arrhenius type plots has led to the determination of average activation energies in typical PZT ceramics. We have found the activation energy to range between 0.29 and 0.32 eV in Navy Type I PZT ceramics and between 0.62 and 0.80 eV in Navy Type III ceramics.

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
