Foxmail client is one of the most popular tools to send and receive e-mail, and the mail data files preserved in it become an important target of computer investigation and forensics, from which the useful clues can be mined out and analyzed. In this paper, a visual Foxmail forensics system is designed to extract the information from the mail evidence file and display the association between the contacts...
This paper highlights that EGARCH(1,1)-M models based on generalized error distribution (GED) , student-t distribution and normal distribution are applied to calculate VaR of day logarithm return series of Shanghai-Shenzhen 300 index, and are compared with GARCH(1,1) model based on normal distribution. The empirical research through statistical analysis and back-testing has shown that EGARCH(1,1)-M...
It is known that there is not a natural generalization for the dimension of multivariate spline spaces, since the dimension of multivariate spline spaces depends not only on the topological property of partition but also on the geometric property of partition. The aim of this paper is to improve the upper bound of the dimension of bivariate spline space for degree k and smoothness mu over arbitrary...
