We theoretically analyze outage probabilities of the lossy-forward (LF), decode-andforward (DF), and adaptive decode-and-forward (ADF) relaying techniques, with the aim of characterizing the impact of the spatial and temporal correlations of the fading variations.First, the exact outage probability expressions are analytically obtained for LF, DF,
Influence of the moist air humidity (10-70%) on the fretting characteristics of steels under grease lubrication is experimentally investigated.Ball (bearing steel, JIS SUJ2) on disk (carbon steel, JIS S15C) type fretting tests for 0-20 mg of grease supplied before each test at the punctual contact between ball and disk were conducted at 50 μm sl
Traumatic brain injury (TBI) is characterized by primary damage to the brain from the external mechanical force and by subsequent secondary injury due to various molecular and pathophysiological responses that eventually lead to neuronal cell death.Secondary brain injury events may occur minutes, hours, or even days after the trauma, and provide va
