 | This CRS Report examines the major, foreign conventional weapon systems that China has acquired or has committed to acquire since 1990, with particular attention to implications for U.S. security concerns. It is not the assumption of this report that China's military, the People's Liberation Army (PLA), will engage in conflict with other forces in Asia. Nonetheless, since the mid-1990s, there has been increasing concern about China's assertiveness in Asia and ... |

| Aviators rely heavily on Forward Looking Infrared (FLIR) imagery. Weather impacted terrain and targets significantly impedes an aircrew's ability to navigate and to rapidly and accurately detect and identify targets. Weather degradation increases target acquisition and identification times, subjecting the aircraft and crew to increased exposure to enemy threats and counterattacks, ultimately decreasing system lethality and survivability. The U.S. Army Engineer Research and Development Center (ERDC), the Air Force Research ... |

| Army personnel are commonly rotated to a night shift, or reverse cycle, in order to have the 24-hour period manned at all times. Working reverse cycle presents problems to personnel due to the difficulty in maintaining alertness during the nighttime hours. This is especially difficult when the shift must be worked several consecutive nights, creating a cumulative sleep dept. Appropriate countermeasures are required to ensure that personnel obtain as much ... |

| Alternobaric Vertigo is a sudden and transient vertigo caused by asymmetrical changes in middle ear pressure (Lundgren - 1965). These changes are directly related to the daily activity of aircraft pilots (and divers). This vertigo strikes often in critical maneuvers (attacks or evasions) causing sudden disoilentation. We used an anonymous enquiry, multiple-choice type, preceded by a briefing about alternobaric vertigo. We found 29% of the pilots with 1 or more ... |

| Electroencephalograms (EEGs) are currently used in many countries to screen Air Force pilots candidates. The usefulness of EEG to predict the likelihood of abnormal activity during the training of cadets remains controversial. We investigated whether effects of normobaric hypoxia on P(300) ERP and memory scanning performance are related to the existence of slow waves in the EEG records of cadet pilots. If so the EEG could serve as a tool ... |
