Magnitude-only resting-state fMRI data have been largely investigated via independent component analysis (ICA) for exacting spatial maps (SMs) and time courses. However, the native complex-valued fMRI data have rarely been studied. Motivated by the significant improvements achieved by ICA of complex-valued task fMRI data than magnitude-only task fMRI data, we present an efficient method for de-noising...
Vehicle safety airbags can protect occupants from vehicle collisions, but there are still some shortcomings, thus need to be constantly improved. In occupant restraint system simulation, the establishment of a reasonable airbag model determines whether the simulation results are consistent with the actual test results. The aim of this study is to establish a precise airbag model for vehicle occupant...
In this paper, we design a social-relations-based routing algorithm (SRBRA). Firstly, by analyzing the real-time data from mobile nodes in the network, we summarize and extract factors that affect social relations between these mobile nodes. Then make inference and evaluation for the complexity and dynamic of these factors from multiple angles, calculate the social-relations values between each sensor...
The cost-optimal trend in global competitive environment has led to lean, complex and consequently vulnerable supply chains. This vulnerability is high due to the presence of increasing dependency in lean supply chain networks. Hence, it is essential for companies to regulate the supply chain network structure and information sharing strategies so as to be more resilient to disruptions/risks. In order...
With the development of Internet, people transmit a large number of digital image every day on the Internet. At the same time, people also begin gradually focusing on the digital image data transmission security issues. First of all, this paper introduces some common image encryption algorithm. Secondly, focusing on the chaotic image encryption technology and focusing on the three-dimensional mapping...
This paper uses the Chinese GEB IPO data from October 2009 to December 2012 to shed light on the autocorrelation of both initial returns and price update and the relations between the initial returns and price update. We find that both initial returns and price update are cyclical. These two variables are positively related. The equal-weighted average monthly initial returns are significantly positive...
So far, the patent law in China has changed for three times, which made the strategy focus from the introduction of foreign advanced technology to enhance the ability of independent innovation. This paper add FDI technology spillover as a mediating variable in the process of analyzing the relationship between patent protection strength and the capability of independent innovation. Selecting domestic,...
The Matched correlation filter based on FPGA is designed for quasi real-time processing of impact acceleration signal in this paper. The design integrates match-filtering algorithm with correlation algorithm, proposing matched correlation algorithm. According to this algorithm, the design uses two Radix-4 FFT modules to complete the correlation operations, using single sine wave as matching model...
A method on edge detection of image was proposed according to the correlation of the multi-scale space in wavelet analysis. The algorithm is fast and easy, in which we do correlation calculation among the adjacent scale wavelet coefficient, and the edge of image can be detected accurately without preprocessing with this method. The experiment results clearly show that the method is efficient, can...
We defined earnings quality as the ability to forecast the future cash flow, stronger forecast capability means higher earnings quality. Choosing all of the A-share in Shanghai and Shenzhen Exchanges between 2001 and 2007, we made a test on the relationship between operating cash flow and accruals. The results demonstrate that the publishing of cash flow can help to increase the financial information...
In order to improve the level of electronic commerce credit rating, we establish a full set of E-commerce credit rating level system, and present a method which based on the combination of a principal component analysis and BP neural networks. This method improved the traditional BP neural networks, by using a principal component analysis could eliminate the correlation between the inputs of neural...
Expressions of Notchl and Cyclin D1 were analysed by immunohistochemical method in the specimens of normal mammary tissue, usual hyperplasia, atypical hyperplasia, cancer in situ, and invasive cancer tissue, which were obtained from the patients operated due to some kind of breast disease. We observed an evidently decreased Notchl and increased cyclin D1 expression respectively from normal tissue...
Channel mismatch, including amplitude and phase mismatch, has severely affected the performance of space-time adaptive processing (STAP). In order to ascertain the specification of the effects on STAP, theory analysis of relation between clutter covariance matrix (CCM) with and without channel mismatch is done based on the model provided by literature, and the effect to signal is also analyzed. In...
