Estimating density from presence/absence data in clustered populations [PDF]
, 2020 Inventories of plant populations are fundamental in ecological research and monitoring, but such surveys are often prone to field assessment errors. Presence/absence (P/A) sampling may have advantages over plant cover assessments for reducing such errors.

A Unified Spatial Framework for Clustered UAV Networks Based on Stochastic Geometry [PDF]
, 2018 To evaluate the system-level performance of clustered unmanned aerial vehicle (UAV) networks, we apply stochastic geometry in order to establish a tractable analytical framework.

Uplink Interference Management for Hetnets Stressed by Clustered Wide-Band Jammers
IEEE Access, 2019 In heterogeneous cellular networks (HetNets), small base stations (SBSs) are overlaid in the coverage region of a macro base station (MBS) to improve coverage and spectral efficiency. However, the performance of HetNets is significantly degraded by inter-

3-D placement schemes of multiple UAVs in NFP-based wireless networks [PDF]
, 2018 In this paper, we propose two placement strategies of multiple unmanned aerial vehicles (UAVs) in network flying platform (NFP)-based wireless networks. The first strategy is based on a proposed distributed placement algorithm (DPA) that can be executed ...

Downlink Power Control: A Performance Booster for Full Duplex Cellular Networks [PDF]
, 2021 Full duplex (FD) communication uses the same time-frequency resource elements for uplink and downlink transmissions. Compared to half-duplex (HD) systems, this improves the effective spectrum usage, but at the cost of additional self-interference and ...

Matérn cluster process with holes at the cluster centers
Statistics & Probability LettersInspired by recent applications of point processes to biological nanonetworks, this paper presents a novel variant of a Matérn cluster process (MCP) in which the points located within a certain distance from the cluster centers are removed. We term this new process the MCP with holes at the cluster center (MCP-H, in short).

Analytical expressions for formal kinetics [PDF]
, 2012 In recent papers Rios and Villa resorted to developments in stochastic geometry to revisit the classical KJMA theory and generalize it for situations in which nuclei were located in space according to both homogeneous and inhomogeneous Poisson point ...
