Vessel noise sources identification system can be modeled by identification system modeling methods such as Artificial Neural Network. The difficulty of experiment and measurement make us unable to get enough real samples to guarantee the quality of identification system modeling. This paper proposes a general method to regenerate virtual samples for identification system modeling based on bootstrap...
The weather factors with on-site EMC measurement may differ a lot from the standard calibration condition, so it is necessary to analyze the impact of weather factors, such as temperature, humidity and atmosphere pressure, on the measurement accuracy of the antennas. Based on experimental study, digital signal processing, improved vector fitting methods and artificial neural networks (ANN), a comprehensive...
The definition of apparent power for unbalanced or non-sinusoidal three-phase power systems still remains a controversial issue at present. By referring to the two schools of prevailing thoughts, i.e. the theoretical approach and the practical approach, a new definition methodology for the apparent power is proposed and deducted, which is called the dual-equivalence approach. A detailed comparative...
