The algorithm to find the novelty temporal pattern from the temporal database is presented. The basic idea of the algorithm is firstly to extract the feature sequence from a time series, then to compare the feature points of the time series with ones of the normal pattern to decide whether there is a novelty pattern in the time series. The temporal relation of time series is reserved in the feature...
Product failure distribution research is a basic research for product advanced design and manufacture, and has an important role in intelligent computing. Traditional analysis of the failure distribution about small samples has some limitations, for example, the weibull distribution test is better as the sample size is more than 10; the Figure test is better as the sample size is more than 20; the...
Some algorithms of close degree in fuzzy pattern recognition were researched and their limitations in application were found. So a new algorithm of close degree was proposed based on fluctuation thought in this paper. The whole relation between various elements and fuzzy set was considered in the new algorithm. It could avoid that the little change of membership grade in fuzzy set result in tremendous...
It requires a quantity of related information to make a comprehensive evaluation on a subject's performance, state, etc. There may all together exist manifold uncertainties with different intrinsic qualities among the information needed, such as fuzziness, ignorance, incompleteness, incomplete reliability of the information etc. Nevertheless, in such cases, current comprehensive evaluation approaches...
The effects of high salinity on the fresh culture and the acclimated culture were investigated by monitoring specific oxygen uptake rate (SOUR), specific nitrification rate (SNR) and specific denitrification rate (SDNR). It was found that the SOUR of the fresh culture decreased from 19.36 to 5.83 mg O2 /g MLVSS *h when the NaCl concentration was raised from 0 g/L to 30 g/L. The SOURs of the acclimated...
The aim of this paper is to study the regional economic difference with the spatial data mining theories. In this paper, we take the per capita agricultural total output value as index variable, and take the township as the basic analysis unit. Based on the ESDA methods (global and local spatial autocorrelation) of spatial data mining theory, including Moran I index, Moran Scatter Plot and LISA, we...
