New Al System could prevent vessel collisions by reducing dependence on ship Captain


Researchers at Texas A&M University have created an intelligent Al system that can help prevent accidents and collisions at sea. Named 'Ship Collision Avoidance of Machine Learning and Radar Technology for Stationary Entities and Avoidance', or SMART-SEA, the platform works to decrease the dependence on ship captains.


The project team was led by Dr Mirjan Fürth, an assistant professor of ocean engineering, who was awarded a contract by the US Department of the Interior (DOI) and the US Department of Energy (DOE) through the Ocean Energy Safety Institute (OESI). It is not completely an autonomous system, rather it provides 'a human-in-theloop', who gives real-time instructions based on maritime traffic,weather and other factors.


This makes navigation safer and easier for the crew, transiting crucial or dangerous waterways by providing additional information and instructions. Collisions between vessels and accidents like ships hitting stationary structures like rigs or lighthouses are becoming common, and most are caused by human error. This Al system will help eliminate that, stated the project team.


Massive vessels have a lot of forward momentum that their shipping distances are measured in miles rather than metres. They also turn very slowly, meaning that any collision has to factor in this slow movement while also adjusting for sensor time lags, ocean current impacts and several other factors.


The Al system has been developed keeping all the above-mentioned factors in mind and is extremely accurate. The research team also said that the system combines raw radar imaging data with machine learning, enabling it to identify moving objects even in bad weather with limited visibility.


The machine learning algorithm detects stationary objects as well from a large distance. The system uses computational fluid dynamics models and machine learning, which have been previously trained on vessel motions, the team added. The system does all of this while complying with International Regulations for Preventing Collisions at Sea (COLREGS).

   An Arizona couple discovered what appeared to be a metal plate from an airplane in their backyard last week. Charlie and Jaclyn High of Phoenix found the white metal piece, which had fallen in their backyard, on Friday, CBS5 reported.
   “I kind of looked around to see if there was anything else, like another piece, or something else other than that, with writing on it. It looks like it’s from an airplane, and you think, oh man, that’s crazy,” Jaclyn told the outlet. According to images shared with CBS5, the metal piece seems to be part of the airplane lavatory.

                          A handwritten note from September 11


      In moments of crisis, our first thoughts are usually to get in contact with the people we love. September 11, 2001, was a day when many people wanted to know that their loved ones were safe. At 9:37 a.m., the Pentagon was attacked by terrorists who crashed an airplane into the western side of the building.

      Many people tried using the mobile phones that existed then, but few were successful. Franklin and Daria Gaillard (Frank and Chip) were both members of the Air Force and worked at the Pentagon. They worked in different parts of the building and had a previous agreement that they would meet at their car in the parking lot if there were any emergency.

      Daria was the first to arrive at the car and wrote a note to Franklin saying "Frank - Sweetie I am okay. I'm w/ my office over by the Lyndon B. Johnson Memorial Sign. I'll stay there till you come. Love lots & lots, Chip." Frank found the note and was able to locate his wife in the aftermath of the attack.

      What makes this story so interesting is the handwritten note. Today, in our digital culture, we have a variety of ways to let people know that we are safe. Text messages, voicemail, and different forms of social media can be used to get the information out to loved ones. In 2001, when these attacks__________(1), the cellular network was still growing and was not as robust as it is today.

      This letter is just one of the many objects that The National Museum of American History_________ (2) since 2001. To learn more, visit our online exhibition September 11th: Bearing Witness to History.
