similarity principle
1.By using the similarity principle of noetic science, the concept of employing the multiple information sources within a DDSS to estimate incomplete information by analogy is proposed. Three types of analogic reJations, namely, approximation, similarity and attribute dependence, are presented for the numerical type of incomplete information. A set of fuzzy linguistic variable-based algorithms for the measurement of the degree of similarity and analogic estimation rules associated with the analogic relations are formulated.
2.The representative samples set is taken as the initial set of Tabu algorithm to further maintain. The method only considers the samples at different classes borders when samples are insert into new training set. The principles of deleting or inserting a sample are the higher categorization accuracy principle and the higher similarity with training set principle.
3.1. Different from those one-dimensional models, this paper includes all variables that affect the transient and time-dependent surface tempreture difference, and establishs a three-dimensional thermodynamic similarity model by means of dimension concordant principle and Buckingham theorem.
4.Based on the hypothesis of similarity for local turbulent characteristics in planetary boundarg layers and the principle of dimensional analysis, and using statistical form of the vertical vortex diffusion coefficient K as well as Ekman spiral wind profile, at vertical dispersion pattern in the 100 km range is derived by numerical analysis method. It is applicable to both flat uniform land and complex terrain.
5.Obtains two kinds of quantity group based on the similitude principle, i.e. the dimensionless similarity criterion and the dimensional thermal stratification height.
6.The mathematic expression of lag - instantaneous unit hydrograph is similar to Pearson type Ⅲ distributioncurve. In accordance with the principle of mathematic similarity, the parameter relation between two methods was established.
7.(3) The method of CBR process derivation based on part key identifier is presented, as well as the principle of similar process case search based on part key identifier and the method of similarity coefficient calculating are expatiated on.
8.Aimed at the limitation of the traditional three points locating method in measuring data registration, a new idea applied the similarity theory to pattern recognition to the registration of measuring data under different viewpoints is presented, where the curvature extremum points in data superposition area are searched with the gradient method, then the feature points in the curvature extremum points according to the principle of gay similitude in pattern recognition are acquired, and the measuring data registration is carried out at the corresponding feature points.
9.An the algorithm to achieve numeral value classification of moss is designed according to foundational principle of numeral taxonomy. The numeral characters of spores and capsule on 33 taxon in moss are analysed by computer. Not only similarity and difference are tested on the basis of their distance coefficient but also coimpared with form and classification.
