    Abstract: Network congestion and signal quality degradation are the major problems of the Global System for Mobile communication (GSM), most especially as the number of customers increases. Consequently, there is a pressing demand for further research to improve network performance. However, congestion in various systems has always been tackled with various ... Show More

    Abstract: This article discusses the modification of three step iteration method to solve nonlinear equations f (x)=0. The new iterative method is formed from a combination of Newton, Halley, and Chebyshev methods. To reduce the number of evaluation functions, some derivatives in this method are estimated by Taylor polynomials. Using analysis of convergence ... Show More

    Abstract: In this study a model based approach is adopted and a robust estimator of the jackknifed Nadaraya Watson estimator of the finite population total is proposed by incorporating the jackknifed procedure into the nonparametric regression estimator (the case of Nadaraya Watson). The study sought to estimate the finite population total using the proposed... Show More
