The paper is to establish a feasible evaluating indicator system for university endowment funds based on principle component analysis. According to information provided by the reference index system from nearly 8000 schools were selected, the 16 indicators were proposed and 1340 schools were selected as the alternative school for investment objectives. By using data envelopment analysis (DEA), 30...
The leaf area index (LAI) provides critical information about vegetation density and vitality, and the temporal feature of field crops' green LAI could provide valuable information about the growing status, including environmental stresses, of crops. Quantitatively mapping the spatial and temporal variations of crop growth conditions has been enabled by the emerging of a large number of remote sensing...
Waterlogging, including flooding, is one of the serious agricultural disasters for winter wheat in the middle and lower reaches of the Yangtze River region, especially during the spring. It's of great practical value to discriminating the impact of waterlogging and flooding on winter wheat efficiently in the field. In this study, we combined the field campaign and satellite remote sensing data to...
Sugarcane is one of the most important economic crops in south China. It's of practical value to quickly assess the leaf area index (LAI) of sugarcane and evaluate its growing state. Field-based or in situ measurements are very labor intensive and time consuming, while satellite images are relatively coarse and unsuitable for real-time crop monitoring, not to mention the cloud-prone climate in south...
Bidirectional Reflectance Distribution Function (BRDF) describes the anisotropic distribution of surface reflectance. Bidirectional Reflectance Factor (BRF) is an alternative parameter to BRDF and is measurable while BRDF is only a theoretical concept. Land surface albedo plays a crucial role in climate and biosphere modeling. Paddy rice is a special crop type which grows in the water flooded environment...
In embedded systems, it brings great benefits to use NAND flash for dynamic data exchange like using RAM, since RAM is usually expensive and consumes much energy. However, the major hardware limitations of NAND flash make it difficult to directly and dynamically read\write\erase on NAND flash. Traditional virtual memory systems are all based on flash translation layer and file system, which lead to...
A new clustering classification approach based on fuzzy closeness relationship (FCR) is studied in this paper. As we know, fuzzy clustering classification is one of important and valid methods to knowledge discovery. One of problems in fuzzy clustering classification is to determine a certain fuzzy sample classification in given limited sample space. Another is its validity, that is to say, if the...
The paper conducts a comprehensive evaluation technique from a three-dimensional view, in which an evaluation model with three dimensions of “history”, “status” and “future” is constructed. Then, the research on science research capability of national defense university based on the niche theory as an example is pulled into to illustrate the feasibility of the methodology from the empirical perspective...
