This paper introduces a multi-level power quality assessment approach towards virtual testing of more electric aircraft. Three levels with increasing accuracies are rough, approximated and exact power quality assessment. The requirement to the accuracy of power quality assessment strongly depends on different analysis jobs. With the multi-level power quality assessment approach, both sufficient accuracy...
With the rapid development of P2P, there are some new applications such as P2PSIP and intercommunication of heterogeneous DHTs (Distributed Hash Table). In those scenarios, there need some nodes acting as proxies and gateways. Such nodes as proxies or gateways in P2P overlays were called Supernodes. The problem of which nodes would be the supernode s was answered by SN election. To choose an eligible...
The similar growth mechanism of equipment scale and single species scale was analyzed. Then, take the equipment expenditure scale as monetary measurement of equipment scale, the basic growth model of equipment expenditure scale was established on the base of Multhus model of single species growth. Next, take the equipment expenditure scale growth ratio as linear minus function, the basic model was...
