| The purpose of our investigation was to determine if computer-based selection tests could predict training track assignment for student naval aviators. This study evaluated the predictive efficacy of an experimental battery of computer-based pilot selection tests for training classification. Student naval aviators are currently assigned to an aircraft training track based primarily on performance in primary training. Students were tested on the experimental test battery and classified into one of ... |

| The lack of visual information and cues in night vision images has produced a history of in-flight mishaps where night vision devices (NVDS) were used as the primary source of sight. In an effort to produce improved night vision images and thereby reduce in-flight mishaps, a video enhancement technique, the sharper image, was developed to enhance, filter, and study images generated by NVDS. The sharper image technique enhances night vision ... |
