Abstract

fetched live from OpenAlex

Design and simulation of a new type of tubular steel electro-thermal actuator capable of vertical displacement is presented. The Tubular Thermal Actuator (TTA) consists of several multiple cascaded chevron-shaped structures, which are connected together by a top ring, as a platform to carry vertical displacement. The TTA is made from a 20 μm thick steel tube with an outer diameter of 1mm by laser micromachining technology. A finite element model was developed to simulate the behavior of the actuator and study the dominant heat transfer mode at this scale. The actuator could generate more than 7 μm linear motion and 2 mN forces at the top ring. In order to avoid operating the tubular actuator at its natural resonant frequencies, modal analysis has also been conducted.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
