Spatial and Social Paradigms for Interference and Coverage Analysis in Underlay D2D Network [PDF]

open access: yes, 2017
The homogeneous Poisson point process (PPP) is widely used to model spatial distribution of base stations and mobile terminals. The same process can be used to model underlay device-to-device (D2D) network, however, neglecting homophilic relation for D2D

On Coverage Probability in Uplink NOMA With Instantaneous Signal Power-Based User Ranking [PDF]

open access: yesIEEE Wireless Communications Letters, 2019
In uplink non-orthogonal multiple access (NOMA) networks, the order of decoding at the base station (BS) depends on the received instantaneous signal powers (ISPs). Therefore, the signal-to-interference ratio (SIR) coverage probability for an uplink NOMA

Heterogeneity in the spread and control of infectious disease: consequences for the elimination of canine rabies [PDF]

open access: yes, 2015
Understanding the factors influencing vaccination campaign effectiveness is vital in designing efficient disease elimination programmes. We investigated the importance of spatial heterogeneity in vaccination coverage and human-mediated dog movements for ...

Better Confidence Intervals for a Binomial Proportion

open access: yesCommunications, 2010
Interval estimation of a binomial proportion is one of the basic problems in statistics. In technical practice a binomial proportion is often used in statistical quality control.

Coverage Probabilities of Bootstrap-Confidence Intervals for Quantiles [PDF]

open access: yesThe Annals of Statistics, 1991
An asymptotic expansion of length 2 is established for the coverage probabilities of confidence intervals for the underlying $q$-quantile which are derived by bootstrapping the sample $q$-quantile. The corresponding level error turns out to be of order $O(n^{-1/2})$ which is unexpectedly low.

Downlink Coverage Probability in Cellular Networks With Poisson–Poisson Cluster Deployed Base Stations [PDF]

open access: yesIEEE Wireless Communications Letters, 2018
Poisson–Poisson cluster processes (PPCPs) are a class of point processes exhibiting attractive point patterns. Recently, PPCPs have been actively studied for modeling and analysis of heterogeneous cellular networks and device-to-device networks. However,

Modeling the conformality of atomic layer deposition: the effect of sticking probability [PDF]

open access: yes, 2009
The key advantage of atomic layer deposition (ALD) is undoubtedly the excellent step coverage, which allows for conformal deposition of thin films in high-aspect-ratio structures. In this paper, a model is proposed to predict the deposited film thickness

Confidence intervals for the coefficient of variation and the difference between coefficients of variation of inverse-gamma distributions [PDF]

open access: yesSongklanakarin Journal of Science and Technology (SJST), 2022
The aim of this study is to establish new confidence intervals for the single coefficient of variation of an inversegamma distribution using Bayesian methods based on the Jeffreys, reference, and uniform priors and compare them with the Wald method. The
