Research on oil-water two-phase flow using 3D random network model;

The application of heat release rate of fuel in fire network model;

Research on retained polymer distribution laws by three-dimension network model;

There are generally three major categories in smoke control models, which are zone model, field model and net model.

By applying Kohonen net model,new conception of weighted value is introduced,weighted values are determined based on entropy and statistical theory,weighted and normalized Minkowsky distance is computed,minimum distance is veried,and similar clustering centers are merged according to hypothesis testing theory.

In order to consider the factors synthetically on safety evaluation, the BP network model is adopted to build up the safety evaluation method of dykes and dams by the artificial neural network.

Based on existing theories and actual values from current standards,the effects of major factors affecting ACSR are quantified,and based on BP network model,the coefficient is estimated using C code.

the cluster′s index is chosen based on the valid precipitation in each growth period and the sensitiveness coefficient,and fuzzy clustering iteration model is utilized to cluster the data of many years precipitation of irrigation section,then the BP network model is formed,finally,the change tendency of the profit and loss of agricultural moisture in the future is forecasted.
