Downlink Performance Analysis in MIMO UAV-Cellular Communication With LOS/NLOS Propagation Under 3D Beamforming

open access: yesIEEE Access, 2022
Integrating unmanned aerial vehicles (UAVs) as the base station is a recent progress and a promising solution to assist cellular networks to improve coverage. In this paper, an analytical framework is proposed to analyze coverage probability and capacity,

Coverage and Energy Efficiency Analysis in Cache-Aided Terahertz Clustered HetNets

open access: yesIEEE Access
Terahertz (THz) communication enables ultra-broadband and low-latency services, but its performance is limited by severe path loss, molecular absorption, blockage sensitivity, and short transmission range.

Environmental heterogeneity blurs the signature of dispersal syndromes on spatial patterns of woody species in a moist tropical forest.

open access: yesPLoS ONE, 2018
We assessed the relative importance of dispersal limitation, environmental heterogeneity and their joint effects as determinants of the spatial patterns of 229 species in the moist tropical forest of Barro Colorado Island (Panama). We differentiated five

A spatial mixed Poisson framework for combination of excess-of-loss and proportional reinsurance contracts [PDF]

open access: yes, 2009
In this paper a purely theoretical reinsurance model is presented, where the reinsurance contract is assumed to be simultaneously of an excess-of-loss and of a proportional type. The stochastic structure of the set of pairs (claim’s arrival time, claim’s

RIS-Assisted Terahertz Clustered HetNets: Coverage and Rate Analysis

open access: yesIEEE Open Journal of the Communications Society
Terahertz (THz) transmission technologies hold significant potential for enabling ultra-broadband in next-generation networks. Despite the vast bandwidth offered by the THz, it faces significant challenges stemming from its limited transmission range.

Simulation of cluster point processes without edge effects [PDF]

open access: yes, 2002
The usual direct method of simulation for cluster processes requires the generation of the parent point process over a region larger than the actual observation window, since we have to allow for all possible parents giving rise to observed daughter ...

Synchronous and Asynchronous Distributions for Poisson Cluster Processes

open access: yesJournal of the Royal Statistical Society Series B: Statistical Methodology, 1975
Summary A simple relation between the synchronous and asynchronous distributions of a Poisson cluster process is proved. This is used in conjunction with the Palm–Khintchine equations to derive an expression for the counting distribution of such a process.

Deterministic walk on Poisson point process

open access: yesESAIM: Proceedings and Surveys, 2017
A deterministic walk on a Poisson point process in Rd is an oriented graph where each point of the process is connected to only one other point following a deterministic and stationary rule of connection.
