In this paper, we presented the applications of the generalization of ZZ transform for finding the exact solution to Volterra integral equations of the second type. The convolution theorem for this transform was demonstrated and applied in three examples. It was shown that this transform facilitated the mathematical operations in finding the exact solution

In this Work, we define the Emad-Falih in Bi-complex space with convergence requirements. Additionally, we determine its fundamental features. We show an example of using the Bi-complex Emad- Falih integral transform to solve differential equations involving Bi- complex –valued functions

. In this paper, we are studying three simulation methods to generate observation for multivariate normal distribution, and these methods are: Matlab mvnrnd, decomposition and conditional methods, and we put simulation programs for each method by Matlab 2015a software, and comparison between these methods by depend on many criterions as MSE, AIC, skw, kur. As well as the run speed criterion for each method to get the best method.

In this paper, we are studying three simulation methods to generate observation for bivariate exponential distribution, and these methods are: method 1, method 2(conditional method) and method 3, and we write simulation programs for each method by Matlab 2015a software, and comparison between these methods by depend on many criterions as MSE, AIC, skw, kur. As well as the run speed criterion for each method to get the best method
