Based on rod-plane electrodes in oil-paper insulation, the experiments for developing characteristics of partial discharge (PD) were performed using constant voltage method. Four statistical spectra and 29 characteristic values were extracted on the basis of the phase-resolved partial discharge (PRPD) pattern. Then 8 new parameters were extracted from the 29 characteristic values by using kernel principal...
High exhaust gas temperature of boiler would seriously affect the boiler efficiency. Due to the large thermal capacity and thermal parameters' inertia in supercritical boiler, it was important to control accurately the exhaust gas temperature in the process of operation. The paper applied the Least Square Support Vector Machine (LSSVM) to build the studying model of exhaust gas temperature through...
In this paper, a liver disease diagnosis based on Gabor filters is proposed. Three kinds of liver diseases are identified: cyst, hepatoma and cavernous hemangioma. The diagnosis scheme includes two steps: features extraction and classification. The features derived from Gabor filters are obtained from the ROIs among the normal and abnormal CT images. In the classification step the SVM classifier is...
