Scientists from the Massachusetts Institute of Technology (MIT) in the United States have developed an application for the Android operating system that can detect changes in the integrity of bridge structures and predict its collapse. The app can collect data from the smartphone’s accelerometer, tuning in to natural vibrations known as modal frequencies. Their change may indicate that the integrity of the structure is broken and the likelihood of the bridge’s collapse has increased. Usually, special stationary sensors are installed on the bridges, which analyze modal frequencies, but scientists decided to prove that an ordinary smartphone can handle this work.
The development was tested on the Golden Gate suspension bridge in San Francisco. The researchers drove across the bridge with a smartphone and an app running on it 102 times. They also asked Uber drivers to drive across the bridge with the app on, 72 times. The data collected by smartphones was compared with the information received by stationary sensors for monitoring modal frequencies – there are 240 of them installed at the Golden Gate. Scientists noted the high accuracy of the measurements obtained by smartphones – in most cases they coincided with the data of traditional sensors. In addition, the application was tested by completing 280 trips over a smaller concrete span bridge located in Ciampino, Italy (bridges of this type are much more common than the Golden Gate). There was a discrepancy with the data of 6 stationary sensors of the bridge, but very small.
The experiments carried out inspired scientists to further improve their development, in their opinion, it can be used even on a national scale. More trips across the bridge would increase the method’s accuracy, the researchers said. In addition, this method is noticeably cheaper than installing stationary sensors on each bridge: mobile devices can be used instead. Scientists believe that the new technology can extend the life of bridges by 15-30%.
“The era of Samsung’s dominance in 10x zoom shots is over,” Galaxy S22 Ultra vs. Vivo X90 Pro+ compared
Reliable insider Ice Universe has posted some more comparison photos comparing the 10x zoom capabilities of the Samsung Galaxy S22 Ultra and Vivo X90 Pro+.
“The era of Samsung’s dominance in 10x zoom shots is over,” Ice Universe said commenting on these shots, adding that he has taken hundreds of similar comparison photos that leave no doubt about the advantage of Vivo X90 Pro +.
Recall that the Vivo X90 Pro + received the main image sensor Sony IMX989 optical format 1 inch and Zeiss optics, consisting of eight elements. He also received a periscope module with a 64-megapixel OmniVision OV64B sensor, which provides 100x zoom. In addition, the Vivo X90 Pro + debuted a 50-megapixel Sony IMX758 sensor.
Yesterday, the same insider already published a comparison of these smartphones at night, stating a large gap between them.
Ice Universe was the first to accurately talk about the new trend of smartphones with waterfall screens, the notch in the iPhone X, the new design of the iPhone 14 and Samsung’s 200-megapixel image sensor. Recently, he was the first to accurately report that Redmi Note 12 Pro + will receive a 200-megapixel main camera. Exclusive information about new products is leaked to him by sources in the research and development department of the South Korean giant.
Mass riots in the “city of the iPhone” showed on video. iPhone 14 deliveries to one of the Apple stores in Latvia have stopped
Well-known insider Ben Geskin, who lives in Latvia, published a video that shows clashes between workers and the security service of the Foxconn plant.
He also reported that the supply of new iPhone 14 smartphones to one of the local Apple stores had completely stopped.
One of my friends just went to our local Apple Store and asked about orders for the iPhone 14. He was told that the supply of smartphones has completely stopped. New orders will take a very long time. The iPhone is good, but I feel most sorry for those people who are locked in the Foxconn factory.
According to Reuters, by the end of November, a further reduction in the supply of iPhone smartphones is expected. Tens of thousands of employees left iPhone City after receiving $1,400 each from Foxconn.
Ben Geskin regularly posts interesting concept art and renders based on rumors and various leaks. He was the first to publish accurate renderings of the iPhone X and iPhone 14, as well as a number of other new products from Apple, Samsung, Xiaomi and other companies.
