In order to reduce the consumed run time and enhance the calculation efficiency for analyzing the propagation properties of an underwater low-frequency electromagnetic wave, a novel approach of modelling the sea with a lossy Drude dispersive medium is proposed. The numerical results of three cases verify the accuracy and validity of the proposed approach.
The environment in a Martian dust storm is critical to the operation of Mars airplanes and rovers due to high speed dust which may cause surface abrasion and equipment failure. In this work, a Martian dust storm simulation wind tunnel (MDSSWT) is designed and numerically investigated. This facility would be capable of performing simulation of the environment inside a Martian dust storm for ground-based...
This study is aimed at the time-domain (TD) electromagnetic compatibility (EMC) modeling of a planar near-field (NF) emission. The radiated EMC model is built, consisting of elementary dipole array, capable of accurate reproduction of NFs emitted by electronic circuits with transient excitations of nanoseconds duration. The details of the modeling approach are explained. The determination method of...
An adaptive fuzzy neural network has been developed to extract fuzzy rules directly from data sample for credit risks assessment. As an application example, a model has been constructed to assess the credit risks in commercial banks by using adaptive neuro-fuzzy inference method. Numerical example indicates fuzzy neural network could fit to assess the credit risk in commercial banks. Furthermore,...
This paper extends to the multi-assets framework the closed-form solution for options with stochastic volatility derived in Heston(1993) and Ball and Roma(1994). This extension introduces a risk premium in the return equation and considers Wishart dynamics for the process of the stochastic volatility matrix, which is the multi-assets simulation of the model of Cox, Ingersoll, and Ross(1985). This...
