The margin trading has entered the pilot run phase since the March 31st, 2010 in China. Selecting the weighted stock as our sample, empirical select the SSE 50 Index as the research object, set suitable time dummy variables, test the impacts of the margin trading to the volatility of the A share stock market in the ups and downs of the stock market via EGARCH and VAR model. The empirical results shows...
In hyperspectral image classification, jointly using the pixels in an image patch can generally improve the performance. Recently, a new hyperspectral image classification method, which is based on low-rank decomposition model, was proposed by Chen et al. Although this algorithm can achieve state-of-the-art performance and outperform many contemporary classification techniques by jointly classifying...
Venture capital started in 1980s in China, the scale of which has grown rapidly in the recent thirty years. As the existence of lock-up period of stock right in our country, venture capital will continue to affect all aspects of corporate governance of the listed corporation after the successful listing. At present, Chinese listing Corporation generally have some problems in financing, mainly for...
Object recognition is a very important task in the field of computer vision. We present a new method for object recognition. The image content is described by the image gradient. Then, the intersection distance is proposed to measure the similarities of the images of different objects. Our method demonstrates good performances on three face data sets.
The recent growing interest for location-based services (LBSs) has created a demand on more accurate and robust object localization approaches. In this paper, the Bayesian compressed sensing (BCS) is employed to localize a single or multiple objects in a wireless sensor network (WSN). This is motivated by the advantages of BCS such as closer to l0-norm, and better performance of reconstruction in...
With the change of business environment for Chinese private companies, performance evaluation system based on EVA and BSC has been introduced into performance evaluation for these companies. This paper describes the status quo of performance evaluation system in Chinese private companies firstly, then discusses the design of performance evaluation system based on EVA and BSC, and finally analyzes...
Evaluate power transformer's operating status correctly is a key issue to its reliable working and the maintenance policy. The Health Index (HI) represents a practical tool that provides the overall health of the asset, among which reasonably determine the weight of each index is the key to guarantee the quality evaluation. While in the current weight determination process, the method of professor's...
The Sanlu milk powder scandal occurred in China in 2008 aroused great international attention to China's quality certification system. This paper studies the current China's quality certification system and points out the fact that the regulatory role played by the Chinese government is practically a monopolized function to “certification” supply. This paper takes China's compulsory product certification...
This article establishes the comprehensive evaluation indexes system from eight aspects that are infrastructure, efficiency of Agro-products logistics, information of Agro-products supply chain, technology of Agro-products supply chain, service quality of Agro-products supply chain, organizational degree of Agro-products supply chain, Agro-products supply chain cost and greening of Agro-products supply...
In recent years, great progress has been achieved in algorithms about image quality assessment (IQA). Several IQA algorithms have been put forward with high correlation with human perception. However, these algorithms can perform even better. In this paper, one strategy is proposed based on region of interest (ROI) in which some alternation on structure similarity (SSIM) are made to enhance the correlation...
