Graphical abstract. Credit: Green Energy and Intelligent Transportation (2023). DOI: 10.1016/j.geits.2023.100130 Researchers from the University of Missouri-Kansas City, School of Computing and Engineering, and independent researchers have developed a model, dubbed GREENSKY, that significantly enhances the energy efficiency and operational time of Unmanned Aerial Vehicles (UAVs) in cellular networks. In the ever-evolving landscape of wireless […]

Q&A: Could automation, electrification of long-haul trucking reduce environmental impacts?

Credit: Unsplash/CC0 Public Domain A new University of Michigan study finds that automation and electrification of long-haul trucking can reduce urban health impacts and environmental damages. For long-haul routes below 300 miles, electrification can reduce air pollution and greenhouse gas damages by 13%, or $587 million annually, according to the study. For long-haul routes above […]
