Abstract

fetched live from OpenAlex

Different night vision goggle image intensification technologies were tested to compare goggle performance in low light conditions. A total of four different night vision goggles were tested in a laboratory dark room and in flight. The laboratory tests consisted of viewing Landolt acuity stimuli of different contrast levels with the different goggles and without the goggles (baseline performance). The initial flight tests involved both a traditional standardized flight test manoeuvre and a novel target visibility rating task, whereas the second set of flight trials involved only the visibility rating task. The results from the laboratory testing indicated that there were significant differences in acuity between the NVGs, particularly for low contrast targets. Flight test data indicated differences between the different NVG technologies that were consistent with the laboratory findings. The implications of these findings are discussed in terms of civil certification of NVG systems.

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.
