Electromagnet design allowing explicit and simultaneous control of minimum wire spacing and field uniformity
Bibliographic record
Abstract
Abstract An adaptive algorithm is presented that works to independently and explicitly control both local power deposition and magnetic field uniformity in a robust, automated manner. The only inputs to the algorithm are the minimum allowable wire spacing, the maximum allowable field error, and the geometry over which to produce the coil. To highlight the function of the algorithm, two examples are investigated: a transverse gradient coil insert, designed for imaging the head and neck; and a highly uniform, low‐power, B 0 field coil. Both examples require highly optimized relative weighting between power dissipation and field uniformity. The algorithm is described and implemented in terms of the boundary element method for coil design. The algorithm is shown to produce acceptable designs; conforming to engineering constraints, for both instances within a matter of minutes. © 2012 Wiley Periodicals, Inc.

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.
