Abstract
<div class="htmlview paragraph">Design and utilization of a planar cable-driven mechanism as a variable stiffness element is investigated for the purpose of the noise and vibration control. The components of the stiffness matrix of a cable-driven mechanism as well as the tensionability criterion and the effectiveness of the stiffness control through antagonistic force control are studied. Two designs of planar mechanisms with variable stiffness are proposed and different aspects of their stiffness are presented and compared. The results showed that the total stiffness of these two designs can be changed 57% and 26%, respectively which means it is possible to build an effective variable stiffness mechanism by controlling the antagonistic forces. The results were verified using a nonlinear simulation. Finally, the linearity is improved by introducing a dual mechanism design.</div>

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
