Research ArticleOpen accessIn the abstractForecasting the Number of Monthly Active Facebook and Twitter Worldwide Users Using ARMA ModelQasem Abu Al-Haija, Qian Mao, Kamal Al NasrIn this study, an Auto-Regressive Moving Average (ARMA) Model with optimal order has been developed to estimate and forecast the short term future numbers of the monthly active Facebook and Twitter worldwide users. In order to pickup the optimal estimation order, we analyzed the model order vs. the corresponding model error in terms of final prediction error. The simulation results … …Journal of Computer Science, Vol. 15, Issue 4 · 19 Apr 2019 · 8,599 accessesView PDFCite
Research ArticleOpen accessIn the abstractSimulated Annealing Decoder for Linear Block CodesLahcen Niharmine, Hicham Bouzkraoui, Ahmed Azouaoui, Youssef HadiIn this study, we introduce a novel soft decoder, the first of its kind, for linear block codes, based on Simulated Annealing algorithm (SA). The main enhancement in our contribution which let our decoder over performs with large gain (about 3 dB at 710-4) the classical SA approach, is to take the most reliable information set of the received codeword … …Journal of Computer Science, Vol. 14, Issue 8 · 4 Sep 2018 · 7,810 accessesView PDFCite
Research ArticleOpen accessIn the abstractOn 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
Research ArticleOpen accessIn the abstractPerformance Evaluation of UE Location Techniques in LTE NetworksYahia Zakaria, Lubomir IvanekThe goal of this research is to evaluate the location accuracy of User Equipment (UE) in Long Term Evolution (LTE) networks which depends on the timing advance parameters. The ability to locate the subscribers through the network is considered as a significant factor in wireless communication systems. The main method to geolocation based on specified distances from many base stations … …American Journal of Applied Sciences, Vol. 14, Issue 1 · 5 Jan 2017 · 8,028 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Empirical Study of Robust Modified Recursive Fits of Moving Average ModelsMohamed Ali Ismail, Hend A. Auda, Joe W. McKean, Mahmoud Mohamed SadekThe time-series Moving Average (MA) model is a nonlinear model; see, for example. For traditional Least Squares (LS) fits, there are several algorithms to use for computing its fit. Since the model is nonlinear, Fuller discusses a Newton-type step algorithm. proposed a recursive algorithm based on a sequence of three linear LS regressions. In this study, we robustify Koreisha and … …Journal of Mathematics and Statistics, Vol. 18, Issue 1 · 28 Jul 2022 · 5,859 accessesView PDFCite
Research ArticleOpen accessIn the abstractEfficient Monte Carlo Algorithm Using Antithetic Variate and Brownian Bridge Techniques for Pricing the Barrier Options with Rebate PaymentsHasan AlzubaidiThe down-and-out call barrier option with rebate payment on dividend-paying stock is simulated using a new version of the Monte Carlo algorithm. The standard Monte Carlo method for simulating such an option suffers from two sources of errors: Hitting time error inherent from time stepping and the Monte Carlo statistical error. We present a modified version of Monte Carlo method … …Journal of Mathematics and Statistics, Vol. 12, Issue 1 · 22 Feb 2016 · 8,259 accessesView PDFCite
Research ArticleOpen accessIn the abstractOn the Need of Source Address for Route-Error Delivery in 6LoWPANShafique Ahmad ChaudhryLow-power Wireless Personal Area Networks (LoWPANs) comprise devices that conform to the IEEE standard 802.15.4. These networks need to be connected with other wireless and wired networks in order to maximize the utilization of information and other resources which are mainly associated with the Internet Protocol (IP)-based networks. The transmission of IPv6 over Low Power Wireless Personal Area Networks (6LoWPANs), … …Journal of Computer Science, Vol. 11, Issue 8 · 15 Nov 2015 · 6,286 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Model for Resolving Flow Parameters for MRI-Neuroimaging ApplicationMoses E. Emetere, M.L. AkinyemiThe functionality of recent neuroimaging using the MRI machine has generated errors which are peculiar to all kinds of MRI processes. Though hardwares are used to complement the MRI process, the problems are not completely solved due to its fundamental errors. The fundamental error is in the exclusion of molecular interaction in the ab-initio Bloch NMR. A new mathematical concept … …American Journal of Applied Sciences, Vol. 12, Issue 9 · 29 Sep 2015 · 6,724 accessesView PDFCite
Research ArticleOpen accessIn the abstractFeasibility Study on Solar Power Plant Utility Grid under Malaysia Feed-in TariffM. Pauzi M. Kassim, Karam M. Al-Obaidi, M. Arkam C. Munaaim, Abd. Mokhti SallehIn Perlis, Northern Malaysia, a solar power plant with an energy capacity of 5 MWp began selling energy to Tenaga Nasional Berhad in January 2013. Upon obtaining Feed-in Tariff approval from the Sustainable Energy Department Authority of Malaysia, the power plant will produce energy with a Feed-in Tariff of RM 0.874 for every kWh for 21 years according to the … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 2 · 27 May 2015 · 8,989 accessesView PDFCite
Research ArticleOpen accessIn the abstractBit Error Rate Analysis of RS (7, 3) Coded Frequency Shift Keying Using SimulinkT.A. Shanmugasundaram, V. VijayabaskarBit Error Rate is an essential parameter to quantize the effectiveness of transceiver circuits used in low power, low duty cycle sensor nodes. BER can figure out their performance in terms of number of retransmissions, which keeps the node to consume its battery power undesirably rather than conserving it. Forward Error Correction schemes ensure the transceiver circuit to effectively perform … …American Journal of Applied Sciences, Vol. 12, Issue 2 · 25 Mar 2015 · 7,047 accessesView PDFCite
