Abstract
The shielding effectiveness of enclosures is predicted by means of a computer simulation based on the finite-element technique. To characterize shielding performance, possible sources of electromagnetic interference (EMI), such as radiated EMI, conducted EMI, grounding, electrostatic discharge and environmental effects, along with their corresponding distances (near- or far-field) to the equipment under test (EUT), are examined. The analysis considers only the penetration of the magnetic field through the walls and apertures, since the electric field attenuation is high when a good conducting material is used for the shield. A finite-element method that is based on a magnetic vector-potential formulation is used; it can be applied to calculate the shielding effectiveness of any arbitrary selected enclosure. The ultimate purpose of this CAD tool is to establish guidelines regarding aperture spacing on the enclosure and to identify regions of high field intensity that must be avoided by designers when locating sensitive circuits.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

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
