A new method using feature subspace for writer identification is proposed in this paper. The current writer identification algorithms are always that the more the extraction features the better the classifier result. However it will result in excessive calculational cost on classifier identification process. On the basis of these issues, after we obtain the high-dimensional features, first we extract...
The decomposition of high concentration pentachlorophenol (PCP) loaded on granular activated carbon (GAC) was studied by dielectric barrier discharge (DBD) plasma. The effects of discharge voltage, treatment time, gas kinds and flow rate on PCP degradation efficiency were discussed. The results indicated that increasing discharge voltage and treatment time could enhance the degradation efficiency...
A brushless DC motor (BLDCM) state equations based on speed error are established in this paper, and a sliding mode controller with a variable structure based on exponential reaching law is designed for speed regulation of BLDCM. Kalman Filter is used to improve the performance in the situation of noise disturbance. The control performances of variable-structure controller presented in this paper...
In this paper, our previous work on the fabrication of four models involving nanometer-size TiO2 and their environmental applications are reviewed. The material characterization and the ability to remove pollutants in water for four models are examined. The obtained models have exhibited excellent photo electrocatalytic activity, high photoconversion efficiency, superior charge separating ability...
