Research ArticleOpen accessIn the author namesManagement of Effective Factors in Components’ Supply Chain on Losses of Electric Distribution SystemM. Esmaeil Honarmand, M. Sadegh Ghazizadeh, Ali KermanshahRestructuring in the electrical distribution utilities, the loss management is one of the critical activities to enhance network efficiency. Accordingly, management of technical loss would be the main target of the asset managers. For loss management, the usual methods of loss calculation and estimation need numerous data which is not used to real networks. In this research, a practical method … …American Journal of Applied Sciences, Vol. 15, Issue 4 · 21 Apr 2018 · 7,551 accessesView PDFCite
Research ArticleOpen accessIn the author namesEmpirical Investigation of TCP Incast Congestion in Wireless Cloud Computing NetworksHamid Sadeq Mahdi Alsultani, Qusay Kanaan, Inteasar Yaseen KhudhairThe promising services offered by cloud computing environments have led to huge amount of data that need to be processed and stored. Wireless cloud networks rely on Transmission Control Protocol/Internet Protocol (TCP/IP) for reliable transfer of data traffic between the cloud end-users and servers and vise-versa. Even though TCP has been successful for several applications, it, however, does not perform … …Journal of Computer Science, Vol. 14, Issue 5 · 3 Mar 2018 · 7,520 accessesView PDFCite

Research ArticleOpen accessIn the author namesOn Bayesian Premium Estimators for Gamma Lindley Model under Squared Error Loss Function and Linex Loss FunctionAhmed Sadoun, Halim Zeghdoudi, Fatma Zohra Attoui, Mohamed Riad RemitaWe consider the Gamma Lindley distribution (GaL) as the conditional distribution of (X|θ,γ), we focus on the estimation of the Bayesian premium under squared error loss function (symmetric) and linear-exponential (Linex) loss function (asymmetric), using informative priors (the Gamma prior). Because of its difficulty and non-linearity, we use a numerical approximation for computing the Bayesian premium. Finally, a simulation and … …Journal of Mathematics and Statistics, Vol. 13, Issue 3 · 23 Sep 2017 · 7,043 accessesView PDFCite
