Structural characterization of electro-thermally driven micro-actuators with immeasurable temperature-dependent material characteristics
Bibliographic record
Abstract
Multi-cell cascaded Electro-Thermal Micro-Actuators (ETMA) made of nickel alloys are analyzed by the finite element (FE) method. The computer simulation runs over the electrical, thermal, and mechanical phases of the ETMA operations. The main challenges of modeling are discussed. Some of the material's parameters such as the electrical resistivity, thermal expansion coefficient and emission are strongly temperature dependent. Furthermore, any measurements of such dependences are complicated by a magnetic phase transition occurring in nickel within the operating range of temperature. All the properties are sensitive to a particular composition of the material. The surface convection is additionally shape-dependent and, mainly due to small dimensions of the actuators, cannot be determined experimentally with sufficient accuracy. For the above reasons the use of the material data estimated from the available literature usually does not render reliable simulations.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
