Downlink Analysis in Unmanned Aerial Vehicle (UAV) Assisted Cellular Networks With Clustered Users
IEEE Access, 2018 The use of unmanned aerial vehicles (UAVs) operating as aerial base stations (BSs) has emerged as a promising solution especially in scenarios requiring rapid deployments (e.g., in the cases of crowded hotspots, sporting events, emergencies, and natural ...

Advanced Engineering Materials, EarlyView.Functionally graded metal–ceramic femoral stems are engineered through continuous UMAT‐based stiffness tailoring, eliminating discrete material interfaces while enhancing biomechanical compatibility. Low‐index power‐law gradation optimizes load transfer, reduces stress shielding, and controls implant–bone micromotion, highlighting a materials‐design ...

Handover management in beyond 5G HetNet topologies with unbalanced user distribution
Digital Communications and NetworksThe increase in user mobility and density in modern cellular networks increases the risk of overloading certain base stations in popular locations such as shopping malls or stadiums, which can result in connection loss for some users. To combat this, the

Transforming spatial point processes into Poisson processes
Stochastic Processes and their Applications, 1999 Let \(N\) be a simple point process in the quadrant \({\mathbb R}_+^2\). The author shows that if the `coordinate sectional' intensities (\(\lambda _1(\omega ,s,t),\lambda _2(\omega ,s,t)\)) exist and if with probability one, \(\int \lambda _1(\omega ,s,t)dt=\infty \) for all \(s>0\), then there exists a family of \({\mathcal F}^1\)-predictable sets \(\

Advanced Engineering Materials, EarlyView.Manufacturing problems such as heat treatment‐induced cracking hinder the widespread application of the laser powder bed fusion (LPBF) process to superalloys. In this study, cracks in the LPBF components of Inconel 738LC superalloy are characterized after heat treatment at various temperature ranges, revealing two distinct cracking behaviors.

Proactive Uplink Interference Management for Nonuniform Heterogeneous Cellular Networks
IEEE Access, 2020 In homogeneous cellular networks, fractional power control (FPC) is employed to partially compensate the path-loss and, hence, improve uplink (UL) signal-to-interference ratio (SIR).
