In this article,we take the Kariba Dam as an example and analyze the number and location of new small dams in detail through Exponential estimation method and Gray Analytic Hierarchy Process. Then,we set up a model and put forward the concrete strategy of regulating water flow. We firstly make a simple...

Online learning is a learning way to use online education platform for learners. It could let the learners start learning at anytime from anywhere by removing the traditional education's time and space limit. As the online learning style becomes more and more popular, its main base environment has gradually...

In this paper we propose one method for mechanical vibration signal analysis. The given mechanical vibration signal is firstly decomposed into several intrinsic mode functions (IMFs) by the empirical mode decomposition (EMD) method. The Hilbert transform of each IMF, calculated by a recently developed...

Based on OpenGL and Google library we established the target model library and the canny operator is used for edge detection. Combined with D-S evidence theory and Pseudo-Zernike moments, the air target recognition algorithm based on information fusion is proposed. Pseudo-Zernike moments are invariant...

In order to remove the mixed noise in an image, proposed a new weighted filtering algorithm. The algorithm used 5x5 filtering window, divided the window into sixteen 2x2 sub-windows, took these median pixel of every sub-window as their virtual center, then calculated the weights of these virtual center...

Basing on scene analysis and VaR calculation, this paper discussed system architecture of scenario calculation and accurate data's importance of system model from the view of system theory. We also discussed several kinds of data errors and their processing methods to avoid the error of data. Then we...
