Examination of the adaptor approach for the measurement of hand-transmitted vibration exposure
Bibliographic record
Abstract
The specific mechanisms of the biodynamic effects is found and the optimized design of the adaptor and its hand-holding strategy is found so that the undesired effects could be minimized. Three adapters were considered and experiment was carried out on a hand-arm vibration test system equipped with an instrumented handle that can measure the tri-axial vibration excitations and the applied grip force. Three subjects participated in the test of the palm adapter and two of them participated in the tests of the other two adapters. The vibration transmissibility functions of the palm adapter under different test conditions are found. The results show that the vibration of a finger adapter could be greatly affected in the frequency range from 25 to 80 Hz, especially in the range (30 to 50 Hz) of the fundamental resonance of the hand-arm system. The rotational vibration is identified as one of the major sources affecting the translational vibration measurement required in the risk assessment of HTV exposure.

Full frame machine prediction
Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
