Network traffic anomaly detection can be done through the self-similar analysis of network traffic. In this case, the abnormal condition of network can be indicated by investigating if the performance parameters of real time data locate at the acceptable ranges. A common method of estimating self-similar parameter is the wavelet transform. However, the wavelet transform fails to exclude the influence...
Determination of dominant periods is a frequently encountered problem in stochastic analysis of hydrologic series data. In this paper, for mining important information about periods in hydrologic system, new idea for estimating periods has been put forward. New method, MSSA (main series spectral analysis method), has been developed. It is to reconstruct the main frequency signals of the original series...
This paper presents a new method for gesture recognition of Human beingspsila hand. This method integrates the features of shape, color and orientation histograms, which are extracted from images, and estimate the comparability with all the different types of gestures by a proposed Expectation-Maximization algorithm in Gaussian mixture model. The classification results were presented based on the...
In inter-molecular multiple quantum coherences (iMQC) experiments, the iMQC signals is easily contaminated by the conventional single-quantum coherence (SQC) signals. How to get the pure iMQC signal is still an open problem for the nuclear magnetic resonance (NMR) scientists. A soft-separation method using blind source separation (BSS) technique was presented to attempt to resolve the problem for...
