Integrating Image Segmentation and Deep Learning to Improve Radio Frequency Propagation Models

International Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT This paper proposes a multi‐sensor approach to improve radio frequency (RF) propagation models, which play a key role in the rapidly expanding field of connected vehicle technology. Focusing on the 1‐ to 20‐GHz frequency range, which is critical for both satellite‐to‐vehicle and base station‐to‐vehicle communications, our study introduces a ...

Functional traits explain responses of Appalachian birds to vertical and horizontal forest structure

Journal of Animal Ecology, EarlyView.
The study of bird–forest relationships dates back decades, but rarely have the relationships of functional traits to 3D forest structure responses been considered for dozens of species at regional scales. Abstract Species interact with habitat based on their functional traits, but it is unclear how specific traits interact with the multiple components ...
