Performance Analysis of CSMA/NP under Finite Population Environments [PDF]

Sensors
In this study, we analyze the CSMA Non-Persistent protocol with a finite number of nodes, providing more accurate results for applications like wireless sensor networks.

Use of an efficient unbiased estimator for finite population mean. [PDF]

PLoS ONE, 2022
In this study, we propose an improved unbiased estimator in estimating the finite population mean using a single auxiliary variable and rank of the auxiliary variable by adopting the Hartley-Ross procedure when some parameters of the auxiliary variable ...

Effects of environmental feedback on species with finite population [PDF]

iScience
Summary: In an unchanging environment, natural selection always selects species with high fitness. In this study, we build a co-evolutionary system to study the interaction between stochasticity in finite populations and environmental feedback.

Spbsampling: An R Package for Spatially Balanced Sampling

Journal of Statistical Software, 2022
The basic idea underpinning the theory of spatially balanced sampling is that units closer to each other provide less information about a target of inference than units farther apart.

Unbiased Estimates for Products of Moments and Cumulants for Finite Populations

Mathematics, 2023
Let FN be the distribution function of a finite real population of size N. Let Fn be the empirical distribution function of a sample of size n drawn from the population without replacement.

Expected mean squares for model effects in the two-way ANOVA model when sampling from finite populations [PDF]

Songklanakarin Journal of Science and Technology (SJST), 2021
The expected mean squares (EMS) for the effects in a two-way ANOVA model are derived when sampling from a finite population, for factors A and B. The A-effects and B-effects are represented by i  and  j , respectively, in the model.

The Efficiency of a Ratio Product Estimator in the Estimation of the Finite Population Coefficient of Variation

Engineering Proceedings, 2023
Ratio product estimators have been proposed by several authors for the estimation of the population mean and population variance, but very few authors have proposed ratio product estimators for the estimation of the population coefficient of variation ...

Analysis of Finite Population Stochastic modeling with State-Dependent Arrival and Service Facilities

Ratio Mathematica, 2022
This paper investigates a stock-dependent arrival process(SDAP) and queue-dependent service process(QDSP) in the stochastic queueing-inventory system(SQIS). The arriving units in the system are generated from the finite source population.
