Abstract

fetched live from OpenAlex

The purpose of this project is to increase the measurement accuracy of the rotation angle and measurement speed. There is one rotatable circular plane with many holes in it, the initial location of this circular plane is stored in a CCD camera and is regarded as a stationary circular plane. When the rotatable circular plane is rotated, the intensity of the light across the holes of two circular planes is changed. This intensity will represent the position of the rotatable circular plane, so the position of that plane can be measured by calculating the intensities of light access between the two planes. In this project, several methods are proposed to increase the accuracy of measurement. To prevent a non- concentricity problem between two circular planes, only one circular plane is used in this system. To reduce the dfficulties in the fabrication process, holes will be used instead of using traditional slits. To increase the reading and calculation speed, an FPGA will be used in this system. For improving sampling accuracy, a Kalman filter is used. Overall, this system can reach an accuracy of 2:2176* 10-5 degree with all angles.

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.

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.
