A prototype machine has been developed to study large-capacity wind turbine generators using high-temperature superconducting technology. The superconducting field windings, using 2G YBCO wires, are used in the rotor, whereas the conventional technology is employed in the stator. The racetrack superconducting magnets are cooled directly by two cryo-refrigerators and the operating temperature is 30...
In aviation, Maintenance, Repair, and Overhaul (MRO) refers to the actions of fixing an air craft when it becomes out of order, or performing routine actions to keep the air craft in working order. MRO services are carried out strictly under the instruction of corresponding MRO task cards, which detail all the information including work content, procedure, equipment, etc. needed for MRO technicians...
For multiple random accesses, a low throughput due to channel contention is the major limitation. The most latency occurs in the contention phase and, therefore, reducing the delay time thus becomes a relevant task. A collision occurs in real network access if two or more packets are simultaneously transmitted. Hence, the contention must be resolved when applying a protocol in the wireless data network...
