A systematic comparison of jet quenching in different fluid-dynamical models

open access: yes, 2010
Comparing four different (ideal and viscous) hydrodynamic models for the evolution of the medium created in 200 AGeV Au-Au collisions, combined with two different models for the path length dependence of parton energy loss, we study the effects of jet ...

An Enhanced Path Loss Model for Maritime Communication Channels

open access: yesIEEE Access
This study proposes a new ocean propagation loss model, the curved ground loss (CGL) model, to improve the existing models by considering the effects of sea surface roughness, earth curvature, and sea wave height on signal fading at the reflection point.

A Path Loss Model for Non-Line-of-Sight Ultraviolet Multiple Scattering Channels

open access: yesEURASIP Journal on Wireless Communications and Networking, 2010
An ultraviolet (UV) signal transmission undergoes rich scattering and strong absorption by atmospheric particulates. We develop a path loss model for a Non-Line-of-Sight (NLOS) link.

Further investigation of empirical path-loss modeling for short forested paths

open access: yesProceedings of the 2012 IEEE International Symposium on Antennas and Propagation, 2012
This paper reports an experimental study of path-loss modeling in foliage environments for VHF and UHF short-range applications. Through the investigation, it is found that although the path loss in a forest can be conveniently modeled using linear regression, it is difficult to apply the extracted information to other forests due to the variety of ...
