Abstract

fetched live from OpenAlex

This paper investigates the application of genetic algorithm and neural network in active control of inflatable structure membrane wrinkles. The membrane to be controlled is a 500mm × 500mm Kapton membrane, pulled by two pairs of forces applied at the four corners along the diagonals. Different combinations of the tensions produce various wrinkles within the membrane. The genetic algorithm is introduced briefly and then used in searching for the optimal force that minimizes the amplitude of the membrane. To predict the membrane flatness in space where direct measurement of membrane flatness is difficult, a neural network model is proposed to map boundary stretching tensions and space environment to membrane flatness. Numerical simulation shows that genetic algorithm works very well in optimizing the tensions and neural network is effective to estimate the flatness of the membrane.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
