This self-driving boat maps underwater terrain

Researchers at The University of Texas at El Paso have constructed a fully autonomous boat that can carry out bathymetric surveys—surveys of the depth and terrain of bodies of water like oceans, rivers and lakes. The team ...

Sounding out a new way to measure gas flow

Researchers at NIST have developed a new—and sound—way to accurately measure the rate at which gas flows in and out of a vessel. The technique, which uses acoustic waves to determine the average temperature of the gas ...

New method can improve explosion detection

Computers can be trained to better detect distant nuclear detonations, chemical blasts and volcano eruptions by learning from artificial explosion signals, according to a new method devised by a University of Alaska Fairbanks ...

A screw that can halve the level of perceived sound

Could noisy neighbors become a thing of the past? If you are disturbed by crashes, bangs, and muffled voices from next door, then you are not alone, but a Malmö University researcher thinks the answer is as simple as a screw.

Scientists use smartphone gyroscopes to sync time across devices

Skoltech researchers have designed a software-based algorithm for synchronizing time across smartphones that can be used in practical tasks requiring simultaneous measurements. This algorithm can essentially help turn several ...

Longitudinal wave

Longitudinal waves are waves that have same direction of oscillations or vibrations along or parallel to their direction of travel, which means that the oscillations of the medium (particle) is in the same direction or opposite direction as the motion of the wave. Mechanical longitudinal waves have been also referred to as compressional waves or compression waves.
