Abstract
Opto-mechanical actuators controlled by high-energy lights represent a new class of non-contact precision actuators based on the photodeformation process. The photodeformation process involves two fundamental opto-piezo(electric)thermoelastic coupling phenomena: 1) the photovoltaic effect and 2) the converse piezoelectric effect. Irradiating high-energy lights, such as lasers or ultraviolet lights, on a certain class of photostrictive materials can trigger the photodeformation and, consequently the induced photodeformation can be used for non-contact precision actuation and control. In the process of photodeformation, the temperature induced pyro-electric effect and the thermal strain effect also affect the overall response. This paper is to evaluate the micro-actuation sensitivity and spatial effectiveness of distributed opto-mechanical shell actuators. Mathematical modeling of a circular cylinder laminated with a segmented opto-mechanical actuator patch is presented first, followed by analytical solution procedures. Various design parameters and micro-control actions, e.g., membrane control, bending control, actuator location, actuator length/size, are evaluated and their modal control sensitivities are reported. Time histories of free and controlled responses are demonstrated.

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
