Abstract

fetched live from OpenAlex

In many applications, it is desired to amplify the motion provided by micropositioning actuators. It is shown that mechanical amplification by lever mechanisms reduces the overall system stiffness, which limits the ability of high frequency operations. In this paper, a hydraulic booster is proposed. If the hydraulic fluid used is not compressible, the system stiffness is not affected. Different designs of the booster are examined experimentally to find a booster without hysteresis. Several experiments are performed to characterize the booster. A model for the booster is proposed and evaluated using experimental data.

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.
