Abstract
The design, analysis and optimization of a novel electromechanical brake for automotive applications is presented . The proposed brake consists of multiple rotating disks immersed in a magnetorheological (MR) fluid, and an enclosed electromagnet. When current is applied to the electromagnet, the MR fluid solidifies as its yield stress varies as a function of the magnetic field applied. This controllable yield stress produces shear friction on the rotating disks, generating the braking torque. An electromagnetic finite element analysis was performed to optimize the magnetic circuit within the MR brake in order to obtain the optimal design parameters that maximize the braking torque generated. Finally, a prototype MR brake was built and tested and the experimental results showed good correlation with the the finite element simulation predictions.

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
