A commercial bank credit risk assessment model based on fuzzy neural network has been established using the credit assessment index system established for commercial banks. This network is a 6 layered structure with 4 factor inputs and one output measuring the credit risk of commercial banks. The fuzzy rule layer has the capability of making necessary adjustments in accordance with specific conditions...
In this paper a method is presented for computing the simplest normal form for a vector field associated with the singularity of two non-semisimple double zero eigenvalues. The method developed here uses the lower order nonlinear terms in the normal form for the simplifications of higher order terms. An explicit formulae are derived, which can be used to compute the coefficients of the simplest normal...
In this paper, a new family of combined iterative methods for the solution of nonlinear equations is presented.The new family of methods is based on Newton's method and the family of sixth-order iterative methods developed by Chun. Per iteration the new methods require three evaluations of the function and two evaluations of its first derivative. Numerical tests show that it takes less number of iterations...
