Data mining can provide support for bank managers to effectively analyze and predict customer churn in the era of big data. After analyzing the reasons for the bank customer churn and the defects of FCM algorithm as a data mining algorithm, a new method of calculating the effectiveness function to improve the FCM algorithm was raised. At the same time, it has been applied to predict bank customer...
This paper presents an electromagnetic tracking method based on two electrically-controlled magnetic sources. Each source consists of three mutual orthogonal coils. The method can skillfully determine the rotation angles of the maximum magnetic flux density vector (MMFD V) generated by a magnetic source according to the Biot-Savart Law. Then the position of the sensor can be calculated with a noniterative...
The particle laden flow over backward facing step is a typical flow for fluid machines. In order to simulating the two-phase flow in the flow, an anisotropic PDF model of particle proposed by author was employed. The standard k-e model was solved to gain the gas flow with finite volume method, and the anisotropic PDF model was calculated by a Finite Analytic/Monte Carlo Method. It is shown that the...
