Abstract
The vibrating flip-flow screen (VFFS) is an effective solution for screening sticky and fine materials. To improve screening efficiency, the flip-flow screen panel (FFSP) must periodically tension and relax, generating high vibration intensity (quantified by the g value). However, an excessively high g value will increase the risk of structural damage (related to its stress value). To address the conflicting of maximizing g value and minimizing stress value, this study proposes a nonlinear modeling and multi-objective optimization framework. The effectiveness of nonlinear model and their superiority over linear model have been verified through experiments. Then, a bi-objective particle swarm optimization (PSO) algorithm is employed to simultaneously optimize the structural and excitation parameters of FFSP, which yields a Pareto front. The Pareto front represents the optimal tradeoff between maximizing g value and minimizing stress value with different weights. The results are validated through numerical simulations. This work offers a practical tool for the design of FFSP, with potential applications in dry deep screening technologies.

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
