During the 5 years following the launch of CBERS-02B in September 2007, China launched a sequence of high-resolution optical satellites that are able to acquire high-resolution images globally. However, most of the satellites launched before 2012 have such poor geometric accuracy, due to both the low technological level of the hardware and design defects, so that their application (e.g., to surveys...
Dow Jones Cbn China 600 Inde is a measure of an indicator of the stock which China's domestic investors can invest in. Through the prediction of the Dow Jones Cbn China 600 Inde, we can predict the future development trend of China's Stock Market. In this paper, we established prediction models based on "most updated" GM(1,1) model and grey dynamic neutral network. The Dow Jones Cbn China...
This paper applies DEA model to a sample of 58 power plate listed companies in the securities market in China in 2008, with a view to identifying the financial risk companies and non-financial risk companies, instead of using ST in the past. Then, after comparing logit regression model and neural network LVQ in predicting the company financial risks, the conclusion was drawn that neural network LVQ...
Based on the neural network theory, this paper proposes the neural network model to solve the surrounding rock displacement prediction of nonlinear problems. This model combines the advantages of wavelet time-frequency analysis and neural network self-learning. The studies had shown that the wavelet neural network had higher prediction accuracy. In addition, it could better reveal the changes of displacement...
