Hyperspectral endmembers are the spectra of pure materials that are responsible for generating the mixed pixels in hyperspectral images (HSIs). Hyperspectral endmember extraction (HEE) is essentially an inverse problem, where the unknown endmembers are inferred from the spectral measurements. Efficient extraction of endmembers in HSI relies on a well-defined generative model that captures key factors...
In order to ensure the safeties of high-speed train, a lot of sensors are installed in the train to real-time monitor its operation status. These sensors collect amounts of data which may be several GBs for one time operation of one train. Such big amount data need to be stored and managed with high efficiency. In this paper, a hybrid storage architecture by combine database and file system is proposed,...
Monthly and seasonal variation characteristics of passenger volume of urban public transport can provide an important basis for the rational planning and operation of public transport. According to the passenger volume information of the public transport of Pingdingshan City, this paper, using Excel, calculates the monthly seasonal index, and then processes them with one-way analysis of variance in...
With the rapid economic development, the logistics industry plays an increasing important role in China. But China's logistics enterprises lack of apparent core competitiveness. Compared with some advanced countries. through identifying and quantifying competitive factors, logistics enterprises can understand their core capability, and thus can provide higher level customer services. The study takes...
Extension provide an effective tool to correctly partition the nature of transient fault and permanent fault, reduce the number of reclosing and to improve stability. This paper presents three element models, that is not fully reflect the nature of things from the general model. Fully reflect the nature of things based on the entire model and things can be resolved conflicting extension element model...
