Widening the draft resources is the key of academic journal of university. To improve the quality and efficiency of university journals' soliciting contributions, a judgment model of highly cited papers in journal of universities was proposed. First, the core elements of high-cited papers were obtained by using the analysis of highly cited papers in China National Knowledge Infrastructure (CNKI)....
Vector quantization encoding requires expensive time to find the closest codeword through the codebook for each input vector. A fast search algorithm for encoding is proposed in this paper. The multilevel elimination criterion is still derived from the three features (mean, variance, and norm) inequalities constraints, but the order of the three inequalities constraints, instead of the predefined...
Fuzzy-logic-control-based (FLC-based) five-stage lithium-ion (Li-ion) battery charger can charge the Li-ion battery with shorter charging time and higher charging efficiency. However, optimal setting of the output membership functions (MFs) is hard to find. In this paper, fuzzy-based Taguchi method is utilized to determine the optimal output MFs. According to the experimental results, the obtained...
This paper discusses the relationship between vegetation index and the above-ground biomass(AGB) of wetland and gets the AGB distribution in the study area, based on the Worldview-2 data and filed sampling data, establishing the East Dong Ting lake as the study area. The results shows that, multiple linear regression model (MLRM) test is significant (hitting a level of 0.000), while the model correlation...
Based on the principles of reliability and maintainability, a type of gun fire control system was taken as research object. The method combining the system composition character with the system reliability index allocation model was used to realize the technique of system reliability. The system failure rate and fault distribution principle were combined with maintainability realization principle...
XQuery Update Facility (XQUF), which provides a declarative way of updating XML, has become recommendation by W3C. The SQL/XML standard, on the other hand, defines XMLType as a column data type in RDBMS environment and defines the standard SQL/XML operator, such as XML Query() to embed XQuery to query XMLType column in RDBMS. Based on this SQL/XML standard, XML enabled RDBMS becomes industrial strength...
This paper, based on 2001–2005 provincial panel data of large & medium industrial enterprises in China, gives an empirical analysis to the FDI technology spillover mechanism in the process of market reform in China. The empirical results show that: 1) in the control of the market conditions, we found that FDI doesn't affect the technological innovation of domestic enterprises; 2) the improvement...
This paper proposed a new objective video quality metric for multimedia videos based on a different perspective. We extended one existing image quality assessment metric to a video quality metric by considering temporal information and converted it into some compensation factor to correct the video quality score obtained in the spatial domain. After some experiments, we find out this proposed quality...
In this paper a new approach based curvature mode ratio (CMR) and natural frequency with BP neutral network for crack injury detection is proposed. Taking a simple cantilever beam with multiple damage and perfect structure as study object, injury indices are gained by way of analysis the merit and drawback of natural frequency and the curvature mode, then use BP neutral network training tests that...
The concept of hi-tech business incubator cluster has been a contentious issue both in the academics and business communities. Based on the discussion of mechanisms and route about endogenous growth of hi-tech business incubators cluster in China, aiming at the status quo of hi-tech business incubators cluster in China with the proposed mechanisms, the paper conducts the grey correlation analysis...
Color quantization is a technique that reduces the number of distinct colors for a color image. It usually maps pixels of the color image to a small color palette. The display quality of the color-quantized image is taken most seriously. But in practical applications, we also need to consider the complexity of quantization algorithm and the storage of parameters. We develop a 3D mathematic model to...
XML and its related technologies have now been in use for almost a decade. There has been considerable amount of effort both from research and industry focusing on XML, XQuery/XPath, XSLT and SQL/XML processing in the database. Many research prototypes and industrial products have been built to satisfy the XML use cases. This paper reviews several use cases where XML databases are leveraged to build...
