Recently, new aeronautical communication systems using L-band and C-band frequencies have been defined as candidates for future communication by the Aeronautical Communication Panel of the International Civil Aviation Organization. The performance of the system may be greatly improved if the Multiple-Input Multiple-Output (MIMO) antenna system is applied to the air-ground communication system. The...
Satellite data communication using geostationary satellites has been introduced for oceanic air traffic control (ATC). Each aircraft needs to log on to a ground earth station (GES) through a satellite before it starts data transmission and log off to finish the communication at the end of a flight. Several hundred aircraft use the link through a satellite at busy times. Once the link is disconnected...
Perovskite thin film electrode for SOFC was prepared on a YSZ single crystal by laser ablation method. The deposited film appeared in pore-free and dense polycrystals oriented in a specific direction. The crystal orientation was controlled by the surface structure of the single crystal substrate. The electrochemical impedance spectroscopy was used to disintegrate the electrode reaction into the constituting...
In this study, the properties of ischemic condition-induced and veratridine-evoked [ 3 H]noradrenaline ([ 3 H]NA) release from rat spinal cord slices were compared. It was expected that ischemia mimicked by oxygen and glucose deprivation results in the impairment of Na + /K + -ATPase with a consequent elevation of the intracellular Na + -level which reverses...
