Most of marine electric propulsion ships are propelled by large electric motors. The speed control of the propulsion motor on the electric propulsion vessel is operated by adjusting the frequency. The power system has the inverter installed semiconductor element, such as IGBT or IGCT, for high-speed switching. However, the inverter for power conversion unit of the electric power propulsion on large...
A speaker verification system (SVS) is developed based on a bank of radial basis function (RBF) neural modules (BRBFNM). The output thresholds of the RBF networks are set using 3-dimensional receiver operating characteristic (ROC) curves. Moreover, a customized cepstral-based feature extraction pre-processing approach is used at each module to select only those features of the speakers that will contribute...
Infrasound is a low frequency acoustic phenomenon that occurs in nature, and can result from man-made events, typically in the frequency range 0.01 Hz to 10 Hz. In this paper we present results for a bank of radial basis function (RBF) neural networks, to discriminate between six different man-made events. Each module in the bank of RBF networks is responsible for classifying one of the six events,...
