Plurality in transformative change: Three co‐created pathways toward nature‐positive Europe(s)

People and Nature, EarlyView.
Abstract The accelerating decline of biodiversity necessitates transformative change to protect nature and society, which requires innovative actions and governance strategies. This paper advances the conceptual understanding of transformative change by identifying patterns of change in three co‐created transformative pathways for a nature‐positive ...

A Case Study to Monitor Parallel‐Connected Ni–Cd Batteries on EMU Trains Through Compositional Data Control Charts

Quality and Reliability Engineering International, EarlyView.
ABSTRACT Electric multiple unit (EMU) trains, widely used in modern railway transportation, use Nickel–Cadmium (Ni–Cd) batteries to power auxiliary systems on board, including lighting, ventilation, control electronics, and emergency systems. These batteries are often connected in parallel to ensure a wider power supply range for electrical loads that ...

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 ...
