Are you looking for a new pastime that will create a balance between physical activity and relaxation? Then yoga may be the perfect choice for you. Yoga can be practiced by people of all ages and levels of fitness.1. It's a great way to strengthen your muscles and become more flexible.
In the 1930s, Indian Sri Tirumali and K. Pattabhi developed one of the most popular forms of yoga practised worldwide today. They worked together using an ancient Sansknt text called Yoga Korunta to create a set routine of yoga movements and breathing exercises. 2.
Ashtanga is different from other forms of yoga. It is a very powerful form of aerobic (有氧的)exercise which creates deep heat in the body. 3. In other forms of yoga, however, the routine can change each time and the stretching exercises aren't aerobic.
4.As well as making you stronger and more flexible, it can also help you to stay calm. By focusing on your breathing while doing physical exercise, you are able to get a balance between mind and body. In addition, yoga helps to make us healthier so we are less likely to get common illnesses like colds.
Furthermore, yoga encourages you to think about what you're doing. Often you will close your eyes while doing certain movements.5.After a few lessons you'll stop looking at what the others around you are doing. You will stop comparing yourself and start focusing on yourself.
A. It can also be done anywhere at any time.
B. The result of their co-operation was ashtanga yoga.
C. Whatever kind of yoga you choose, there are many long-term benefits.
D. This allows you to concentrate better and it makes you less competitive.
E. Every time someone practices ashtanga, he or she does exactly the same movements.
F. If you're interested in yoga, but can find a class near you, then it might be an excuse to travel.
G. Recently, it has become extremely common for beginners as well as advanced yoga students to go on yoga holidays.
Shark attacks not only disturb beach activities, but can affect associated tourist industries. Shark nets are a common solution to preventing shark attacks on beaches, but they cause dangers to sea ecosystems.
Seeking a cost-effective way to monitor beach safety over large areas, we have developed a system called Shark Spotter. It combines artificial intelligence (AI), computing power, and drone (无人机) 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 real-time 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 computer 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 (漂浮仓) together with an electronic shark repellent (驱逐装置) 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 complete rescue operation took 70 seconds.
We believe Shark Spotter is a win-win for both marine life and beachgoers. This unique technology combines 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.
