Predicting air pollution based on extension and fuzzy-cluster analysis
Principal component analysis and cluster analysis of morphological traits in eggplant
The cluster analysis showed the pollution of soil of Pea, Tomato and Cauliflower were serious.
The fuzzy cluster analysis is carried out by using transmission close matrices and the dynamic graph of fuzzy cluster is obtained which can separate the water area successfully.
Thirdly, we grouped samples by cluster analysis, and test that there are significant differences among the groups.
METHODS: Comprehensive evaluation index system of technology innovation capability of pharmaceutical industry was established and factor analysis and cluster analysis were performed.
This paper proposes a novel fault location method. By means of cluster analysis as well as graph theory, the power system is partitioned into several protection zones.
Carried on the cluster analysis of relationship between regional science and technology input and economic growth, the author divided our country into three kinds of regions.
The result of the R cluster analysis is that the most varieties of M halliana which is used in the study of the classification of appearance are independence and stability.
A new R cluster analysis--Multiple R correlation cluster analysis;
Analysis of the Subordinate Function and cluster analysis of Alfalfa Drought Resistance
The fuzzy analogy method consists of two parts: fuzzy cluster analysis and pattern recognizing.
Objective: to take the ways of epidemiological investigation and cluster analysis to classify syndrome of gastritis (Weiwantong).
Hidden age messages of pyrolysis mass spectra data of lacquer film by cluster analysis method were investigated and discussed. The stability of experimental factor influenced on analysis result.
Potassium, cuprum and cobalt are found to be the key factors influencing the titer of erythromycin by co-using attribute reduction EDMAR in rough set and cluster analysis.
Based on a large amount of investigating data, the authors use cluster analysis method with ordered samples to set dividing standards for the growth rate of secondary forests rechange.
Factor analysis and cluster analysis were used to identify the food factors and dietary pattern clusters.
By cluster analysis, the method for quality evaluation of Fructus Aurantii was established.
Using cluster analysis method, the main affecting factors and optimizing mode of regional waste collection and transportation were studied.
The authors have tried to apply fuzzy cluster analysis in fuzzy mathematics to predicting coal and gas outbursts in Pingdingshan mining area, which has been proved practical.

Auto-selected parameter grey relation cluster analysis method based on single-gene disturbance experiment
In this sub-system, a toolbox of multivariate calibration, a toolbox of chemical factor analysis, a toolbox of cluster analysis, a toolbox of overlapping peak resolving were involved.
Various demographic, behavioural, and psychographic patterns are built up using techniques such as cluster analysis.
In this paper,the present condition of E-GOV's performance evaluation index system is discussed. According to the characteristic of every phase,a life cycle index system is established. Fuzzy cluster analysis is applied in order to make the index system more integrated and representative.
So data normalization methods described above should be carefully used in distance cluster analysis for exploratory data.
Based on rank effect in order of size, a principle of the average rank effect is constructed and the ordinal cluster analysis is done for every level of factor.
