Method of finding objects falling on the sea surface

According to scientists, objects falling into the sea are vibrating, also following a separate law of motion, whereby humans can locate falling objects in order to search and rescue.

Nature Communications has published the results of scientists' research on how to find objects falling into the sea when there is a violent wave, during stormy weather.

The falling object may be a lifeboat, or a person who falls from the side of a ship or a black box that falls from an airplane. To find falling objects, at least, one needs to predict where the search will take place. Although the flow of water and the main wind direction can be clearly defined, the lifeguards cannot predict the location of the falling object, because the movement of seawater is random and unpredictable.

According to scientists, objects falling on the sea surface follow the diffusion rules.(Photo: forum.unity3d.com)

Oceanographers hire thousands of floats on the surface of the water, and they use satellite tracking to study the turbulent movement of the ocean. Then, they relied on the results to predict how far away from the initial position of the object to the displaced location.

Four scientists from the Australian National University, Dr. Hua Xia, Dr. Nicolas Francois, Dr. Horst Punzmann and Professor Michael Shats, set out to model the movement of extremely complex water flows , by How to create intense water waves right in the lab.

After a few years of research and manufacture of devices that can generate strong waves of water waves, and develop Angorit algorithms on computers to track many small objects, the team of scientists has achieved results. background and practical significance is very important.

Dr Xia said: "We created water flows in the laboratory by forming strong waves on the surface of the water, and tracking the movement of objects on the surface of the water with high precision. ".

"We recognize that objects that fall in accordance with the law of diffusion are similar to the rules invented in 1905 by the scientist Albert Einstein, who explained the movement of grain in the country. recorded by botanist Robert Brown , " said Dr. Xia.

According to experts, diffusion rules help develop advanced Angorit algorithms, serving search and rescue work. This is also important in other ocean and atmospheric applications, as that rule also helps determine the drift of ocean surface organisms, and the dispersion of substances pollution in the atmosphere, such as ash of volcanic eruptions.
