Transportation — Fueling up on savings

Oak Ridge National Laboratory researchers determined that for every 5 miles per hour that drivers travel over a 50-mph speed limit, fuel economy decreases by 7% and equates to paying an extra 28 cents per gallon at current average U.S. fuel prices.

This finding was released in the updated 2022-23 Fuel Economy Guide, which provides tips to save on fuel. Researchers use data from demonstrations to show impacts on fuel efficiency such as speeding, low tire pressure, neglecting vehicle maintenance or carrying a heavy roof rack.

Seismic — Feeling it out

An Oak Ridge National Laboratory team developed a novel technique using sensors to monitor seismic and acoustic activity and machine learning to differentiate operational activities at facilities from “noise” in the recorded data.

Communications — Space to ground

Oak Ridge National Laboratory is debuting a small satellite ground station that uses high-performance computing to support automated detection of changes to Earth’s landscape. The new system will reduce the time it takes to collect, process and analyze satellite imagery, saving precious seconds when human life may be at risk.

The HPC-enabled automated change detection and satellite integration can help speed emergency response and relief efforts following crises such as wildfires, natural disasters or sudden population migrations.

VA, ORNL and Harvard develop novel method to identify complex medical relationships

A team of researchers from the Department of Veterans Affairs, Oak Ridge National Laboratory, Harvard’s T.H. Chan School of Public Health, Harvard Medical School and Brigham and Women’s Hospital has developed a novel, machine learning–based technique to explore and identify relationships among medical concepts using electronic health record data across multiple healthcare providers.

ORNL neural network study harnesses made-to-order design to pair properties to materials

A study led by researchers at the U.S. Department of Energy’s Oak Ridge National Laboratory could help make materials design as customizable as point-and-click.
