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 ...

The Energy Efficiency of Heterogeneous Cellular Networks Based on the Poisson Hole Process

open access: yesFuture Internet, 2023
In order to decrease energy consumption caused by the dense deployment of pico base stations (PBSs) in heterogeneous cellular networks (HetNets), this paper first analyzes the energy efficiency (EE) of two-tier HetNets and then proposes a method to ...

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

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

Towards a Realistic Assessment of Multiple Antenna HCNs: Residual Additive Transceiver Hardware Impairments and Channel Aging [PDF]

open access: yes, 1947
Given the critical dependence of broadcast channels by the accuracy of channel state information at the transmitter (CSIT), we develop a general downlink model with zero-forcing (ZF) precoding, applied in realistic heterogeneous cellular systems with ...

Performance Analysis of Dense Small Cell Networks With Practical Antenna Heights Under Rician Fading

open access: yesIEEE Access, 2018
In this paper, we examine the combined impacts of distance-dependent Rician fading channel model and the absolute difference between the heights of base station (BS) and user equipment (UE) antennas on the coverage probability and the area spectral ...

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,
