【文章內(nèi)容簡(jiǎn)介】 mile when you greet them and can carry pleasant conversations. In short, they often put on a mask to the outside world while leading seemingly normal and active lives. Inside, however, they often feel hopeless and down, sometimes even having thoughts about ending it all. People with smiling depression put on a happy face to the outside world, but they can experience a lift in their mood as a result of positive occurrences in their lives. Other symptoms of this condition include overeating, feeling a sense of heaviness in the arms and legs and being easily hurt by criticism or rejection. They are also more likely to feel depressed in the evening and feel the need to sleep longer than usual. With other forms of depression, however, your mood might be worse in the morning and you might feel the need for less sleep than you are normally used to. So how can they break this circle? A starting point needs to be known that this condition actually exists and that it39。s serious. Only when we stop ignoring our problems because we think they39。re not serious enough can we start making an actual difference. Then we can find purpose by taking the attention away from ourselves and placing it onto something else. Feeling that our lives matter is finally what gives us purpose and meaning — and this can make a significant difference for our mental health and wellbeing.（1）What do we know about people suffering smiling depression?

Shark nets are a mon solution to preventing shark attacks on beaches, but they cause dangers to sea ecosystems. Seeking a costeffective way to monitor beach safety over large areas, we have developed a system called Shark Spotter. It bines artificial intelligence (AI), puting power, and drone (無(wú)人機(jī)) technology to identify and warn lifesavers to sharks near swimmers. The project is a cooperation between the University of Technology Sydney and The Ripper Group, which is pioneering the use of drones—called Westpac Little Ripper Lifesavers—in the search and rescue movement in Australia. SharkSpotter can detect sharks and other potential threats using realtime aerial imagery. The system analyses video from a camera attached to a drone to monitor beaches for sharks, send warnings, and conduct rescues. Developed with techniques known as deep learning, the Shark Spotter system receives imagery from the drone camera and attempts to identify all objects in the scene. Once certain objects are detected, they are put into one of 16 categories: shark, whale, dolphin, rays, different types of boats, surfers, and swimmers. If a shark is detected, Shark Spotter provides both a visual sign on the puter screen and an audible warning to the operator. The operator confirms the warning and sends text messages from the Shark Spotter system to the Surf Life Savers for further action. In an emergency, the drone is equipped with a lifesaving flotation pod (漂浮倉(cāng)) together with an electronic shark repellent (驅(qū)逐裝置) that can be dropped into the water in cases where swimmers are in severe trouble, trapped in a rip, or if there are sharks close by. In January 2018, the Westpac Little Ripper Lifesavers was used to rescue two young swimmers caught in a rip at Lennox Head, NSW. The drone flew down the beach some 800 meters from the lifeguard station, and a lifesaving flotation pod was dropped from the drone. The plete rescue operation took 70 seconds. We believe Shark Spotter is a winwin for both marine life and beachgoers. This unique technology bines dynamic video image processing AI and advanced drone technology to creatively deal with the global challenge of ensuring safe beaches, protecting environments, and promoting tourism.（1）A Shark Spotter is ________.
