Abstract

fetched live from OpenAlex

This paper investigates the application of genetic algorithm in active control of inflatable structure membrane wrinkles. The membrane to be controlled is a 200mm × 300mm rectangular Kapton membrane, pulled by three tensions along each edge. Different combinations of the tensions produce various wrinkles on the membrane. An active control system is developed to improve membrane flatness by adjusting the tensions. The control system is based on genetic algorithm, which searches for the best tension combinations to minimize the membrane wrinkle amplitude. Experiments are performed and results show that genetic algorithm works very well in finding the optimal tensions.

Full frame distilled prediction

Teacher imitation

Not 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.
