In this study, a chaotic analysis approach was applied to a time series composed of seismic moment of events occurred in mine of Dong Gaussian copper mine subordinate to Tong Ling Nonferrous Metals Group Co. In Anhui province, China. The chaotic attractor dimension and the largest lyapunov index were put forward to determine whether the seismic flow of rock is chaotic and the degree of chaos. The...
Ground based SAR system has many applications in ground structures monitoring. Normally, the radar system is constructed by linear frequency modulation. Pseudo-random code has the properties that its autocorrelation function has sharp peak like noise. In this paper, a new ground based SAR system based on code phase modulation is proposed, and the constructive diagram of ground based pseudo random...
Through empirical study, this paper tests the effect of member age of the board of directors and independent characteristics on corporate performance from 863 listed companies of Japan, and the result shows that average member age of the board of directors and corporate performance are significantly positively correlated, independent director system is advantageous in improving corporate performance,...
The space-air-ground integrated network is based on the modern communication networks and integrated the latest communication and computer technologies, such that connects all various networks together to form a very huge and complicated network topology that has the best sharing of the global information and resources. This paper is treating the communication network as a space which is formed by...
Sea surface drag coefficient CD is fitted by four wind-wave parameters that are wave age, wave steepness, windsea Reynolds number RB and RH directly, with laboratory, field and combined data set. Comparison and analysis of dependence of CD on wind-wave parameters show that, among the four wind-wave parameters, windsea Reynolds number RB can fit the CD most appropriately.
The previous study of pattern discovery in storage systems focus on sequential pattern (SP) mining in lower level traces, but they don't scale well to the application level. For patterns in application level are mostly composed of Contiguous Item Sequential Patterns (CISP) which are much simpler than SP, so it's inefficient for the previous studies to mine CISP with clumsy SP mining algorithms. We...
Image resolution is an important factor affecting face recognition by human and computer. We propose a new nonlinear warping method to align the facial images of the training set, which is then used to predict high resolution facial image from a signal input low resolution facial image. Using sparse initial mesh specified by the facial feature points and a special designed subdivision mesh algorithm,...

Several methods are studied in order to improve the communication reliability. However, little methods are discussed aim at medium-voltage power line communication (MV-PLC). In this paper, the general idea of the noise elimination based on single-phase line has been changed. There is a new idea to use three-phase line for noise offset. By analysis of the noise correlation properties, the LMS adaptive...
To estimate software effort according to software size, statistical analysis was held using the historical project data. The tool statistics method and the programming statistics method were adopted independently for linearity regression analysis. After the regression analysis, the linearity regression equation was obtained. The final studies showed that the outcomes obtained by these two methods...
