Information security risk assessment is essential to government for making an efficient and effective security management plan. This paper firstly established a hierarchy structure index system for E-government information systems security risk assessment based on the operationally critical threat, assets and vulnerability evaluation (OCTAVE). Considering that the previous weights selection methods...
In this article, the mathematical statistical model and artificial neural network model are established and used to predict the fiber diameter of spunbonding nonwovens. The artificial neural network model has good approximation capability and fast convergence rate, and is employed in this research. The results show it can provide quantitative predictions of fiber diameter and yield more accurate and...
Attempt to recognize pattern of meteorological parameters over the smaller scale geographical region (district) artificial neural network models have been developed. 54 years data for 1951-2004 have been used, of which the first 41 years (1951-1991) of data are used for training the network and data for the period 1991-2004 are used independently for validation. We have found that the mean absolute...
