An Indoor Channel Model for High Data-Rate Communications in D-Band

open access: yesIEEE Access, 2020
This paper proposes a measurement based modeling of D-band indoor channels. Different indoor environments were considered including Line-of-Sight (LOS) and Non Line-of-Sight (NLOS) conditions.

Process‐Informed Analysis of As‐Built Metal Additive Surface Features

open access: yesAdvanced Engineering Materials, EarlyView.
This article introduces a novel method for feature‐based surface texture characterisation directly incorporating manufacturing variables into the feature extraction workflow. This marks a major step towards identifying process‐specific surface properties and their influence on part function and hence a holistic understanding of process–structure ...

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 ...

Average Error Probability Analysis in mmWave Cellular Networks

open access: yes, 2015
In this paper, a mathematical framework for the analysis of average symbol error probability (ASEP) in millimeter wave (mmWave) cellular networks with Poisson Point Process (PPP) distributed base stations (BSs) is developed using tools from stochastic ...

Vehicle-to-Vehicle Communications with Urban Intersection Path Loss Models [PDF]

open access: yes, 2016
Vehicle-to-vehicle (V2V) communication can improve road safety and traffic efficiency, particularly around critical areas such as intersections. We analytically derive V2V success probability near an urban intersection, based on empirically supported ...

Pore Size Effects of Mesoporous N‐Doped Carbon Nanospheres as Advanced Support Material on the Activity of Molybdenum Sulfide Catalysts for the Hydrogen Evolution Reaction

open access: yesAdvanced Functional Materials, EarlyView.
By tuning the pore size of mesoporous N‐doped carbon (MPNC) nanospheres as support material for molybdenum sulfide, the electrochemical activity of the composite material for the hydrogen evolution reaction can be optimized. An ideal MPNC pore size of 60 nm allows a high number of molybdenum sulfide active sites while maintaining efficient proton and ...

Adaptive Observer-Based Line-of-Sight Guidance Law for Path Following of Underactuated Unmanned Surface Vehicle With Sideslip Compensation

open access: yesIEEE Access
In this paper, the path following problem of an underactuated unmanned surface vehicle (USV) in the presence of environmental disturbances is considered. To compensate for the sideslip induced by drift forces, an adaptive Kalman-like observer is proposed

Artifact‐Minimizing Ultrathin Transparent Electrodes Fabricated via iCVD for In Vivo Optogenetic Stimulation and Neural Signal Monitoring of Primary Visual Cortex

open access: yesAdvanced Functional Materials, EarlyView.
We present ultrathin flexible transparent electrodes through iCVD‐enabled molecular control of 10 nm gold films on poly(dimethylaminomethylstyrene). In vivo validation demonstrated photoelectric artifact reduction vs. opaque electrodes and preservation of natural neural dynamics.
