This paper studies the structure features of the collected power consumers' power consumption data, in which the 96 measured data points indicating a single user's power consumption curve of a day. The 96 measured data points are taken as 96 variables for analysis. The dimensionality of original data is reduced by principal component analysis (PCA), and then the K-means algorithm is employed to cluster...
In this paper, an ideal proposed that improving the accuracy of the road information by enhancing the quality of image source. Apply the image information fusion algorithm that based on HIS transform and wavelet transform to the multi-spectral remote sensing images and QuickBird panchromatic remote sensing images fusion, the experimental results show that the quality of image source is substantially...
The vibration signal is very important to the bridge healthy monitoring, because the variation of bridge vibration frequency indicates the changing of bridge structure state. Wavelet analysis theory is applied in this paper and study to analyses the monitoring data of bridge vibration signals in the bridge health monitoring system, and through multi-scale decomposition and reconstruction, as well...
