    The Basic Reproduction Number for the Markovian SIR-Type Epidemic Models: Comparison and Consistency by Muteb Faraj Alharthi

    Published 2022-01-01
    “…The first is to examine Bayesian sensitivity and consistency of this measure for the case of Markov epidemic models. The second is to assess the Martingale method by comparing its performance to that of Markov Chain Monte Carlo (MCMC) methods in terms of estimating this parameter and the infection and removal rate parameters given only removal data. …”

    Non-Markovian spiking statistics of a neuron with delayed feedback in presence of refractoriness by Kseniia Kravchuk, Alexander Vidybida

    Published 2013-08-01
    “…    Recently, [35,6], it was proven for a neuron withdelayed feedback and without the refractory state,that the output stream of interspike intervals (ISI)cannot be represented as a Markov process.The refractory state presence, in a sense limits the memory range in thespiking process, which might restore Markov property to the ISI stream.…”

    Cooperative ARQ protocol based on switch and stay node selection in WSN by HU Ying-bo1, CAI Yue-ming1

    Published 2010-01-01
    “…A cooperative automatic repeat request(ARQ) protocol based on switch and stay node selection(SSNS-CARQ) was proposed,which could obtain high energy efficiency and reliable transmission at the same time.A Markov model for analyzing the system throughput was built,and system throughput performance of the proposed protocol and the traditional ARQ protocol were analyzed based on such model.Based on a widely used energy consumption model in WSN,the energy consumption performance of SSNS-CARQ protocol and the traditional ARQ protocol were discussed and compared in terms of energy efficiency,and the effects that positions of relay nodes imposed on energy efficiency were also disscussed.Numerical and simulation results validated the Markov model effective for analyzing the system throughput.It is shown that SSNS-CARQ protocol could perform better in terms of throughput and energy efficiency when compared with the traditional ARQ protocol through simulations.…”
