Tractor-trailer trucks may leave a different "footprint" in the near future. Heavy trucks outfitted with single wide-based tires instead of the conventional dual tires are more fuel efficient, according to a study sponsored by DOE's Office of Vehicle Technologies. A paper from DOE's Oak Ridge Nation...
Unsuspecting subjects could be identified in mere seconds with a novel recognition system being developed by researchers at Oak Ridge National Laboratory. Unlike conventional technologies that look at a facial feature or the iris, ORNL's off-angle multi-modal biometric recognition system captures se...
A prototype data-analysis software developed at Oak Ridge National Laboratory could help track potential terrorist groups by uncovering hidden meaning in the group's written interactions. The method can extract emotional content known as affective meaning from unstructured text documents like blogs,...
Sapphire nanowires grow using an unexpectedly complicated reaction with oxygen atoms changing between partners in vapor, liquid and solid phases. By concentrating on the triple-junction of the three phases, observations captured with high-resolution electron microscopy at the atomic scale, at high ...
A prototype charging system for electric and hybrid vehicles is helping demonstrate a technology that could one day play a key role in the electrification of America's highways. The bench-scale prototype developed at Oak Ridge National Laboratory is allowing researchers to quantify the power transfe...
A vehicle monitoring study at Oak Ridge National Laboratory could help transform energy-intensive vehicles like transit buses and utility trucks into energy-efficient equipment. ORNL researchers have installed data acquisition and wireless communication systems on several East Tennessee heavy vehic...
cylinder engine, they demonstrated a new potential for passenger-size diesel engines. They also reached a Department of Energy joule milestone and ...
A research team led by Peter C. Lichtner of Los Alamos National Laboratory (LANL) is using the Oak Ridge Leadership Computing Facility's (OLCF's) Jaguar supercomputer, located at Oak Ridge National Laboratory (ORNL), to build a three-dimensional model of an underground uranium waste plume
Wireless sensors that alert steel mill operators to abnormal temperatures and vibrations that foretell wasted energy and imminent failure are expected to pay big dividends. Through the Department of Energy's Industrial Technologies Program, Oak Ridge National Laboratory has been commissioned to inst...
Instead of the conventional long piece of metal or dipole antenna, electronic devices of tomorrow could incorporate an antenna no bigger than a gnat. This is made possible by a design that allows an electrically charged nano-mechanical oscillator to be tuned to specific electromagnetic waves. "Gon...
