End the use of micro-channel positioning three places will be able to draw three circles precise positioningSa Sa circle to draw the micro-channel can be positioned reporter test proved that the Nike Heels Boots rumors are true, experts say the use of the mathematical principles of the law enforcement authorities plane geometry prompts the user with caution positioning function using micro letter 'close to people' function, more than three times the position of continuous transformation, supplemented by e-map , will be able to locate the other micro channel where users! Reporters tests had confirmed that the rumors are true network and follow the principles of mathematics experts interpret them. Municipality multiple causes of crime caused by micro-channel positioning has occurred, which took most of Chaoyang District. Reporters will test report Nike Shoes to the Chaoyang Court, attention. This morning, the Chaoyang Court, safety tips, judges hope that through this newspaper to remind users to use caution micro letter positioning function, protect against criminal violations. Internet rumors micro-channel can be positioned to find the 'nearby' and online there is a saying, the use of micro letter 'close to people' this feature, you can locate others. Micro-letters 'nearby people' feature can help users nike dunk heels find the micro-channel micro-channel users away from their other within 1000 meters. According to the net posts described, found in the micro-channel 'nearby people' function in a specific object, note the distance between themselves and each other, after changing positions himself twice, re-measured distance themselves and each other, and finally to three times the measurement location for the center, the three a distance radius draw Nike Air Force 1 three circles, three circles overlap position is a position where the other party. Reporters test field test three targeted Internet rumors bearing the credibility of opinions. Recently, a reporter at a beauty with, in the vicinity of the North Third Ring Road outside Kin Tak bridge test. And after reporters separately, the beauty 'hiding' a nearby shop, but the exact location has not told reporters. Reporters then use the micro-channel 'nearby' and function, in healthy Dement subway station A port (with each other within a distance of 500 meters), in the Garden District Xin (with each other within Air Jordan 18 a distance of 300 meters), Taipei Medical school to the north gate (with each other within a distance of 100 meters) three sites to be tested. Subsequently, the reporter using electronic map, with net posts professor ways to determine the position of the other party in the home district north of Washington. Call reporter to confirm beauty, the other exclaimed: '!? I was in Washington in the home district north of the Bottom how do you know', the reporter again in cooperation with each other, in Chaoyang, Haidian, Fengtai and other places Repeat tests were successfully make positioning. Expert interpretation of the principle is not difficult to use plane geometry knowledge 'just use the intersection of plane geometry seek knowledge, is also not difficult.' Professor of Mathematical Sciences, Beijing Normal University 王昆扬 he said. Wang then explain to establish Cartesian coordinates (see above) on the Air Jordan 13 Retro map. When provided by the searcher's coordinates Z, the first position searcher for A, A and Z in the known distance longer than 500 meters, the mean Z to A as the center is located 500 meters radius of the inner circle anywhere. Similarly, when the searcher is located in position B, the position C, B and known distance Z, C and Z were less 300 meters and less than or equal to 100 meters, which means that Z is located in B and C of a circle, with corresponding distance to any location within a radius of the circle. Then we can conclude that: Z coordinate position located three circles overlap region. Professor Wang said: 'If the searcher can transform more locations that draw more circles, overlapping area will be smaller, the positioning accuracy will be higher.' But Professor Wang told reporters, converting multiple locations using micro letter positioning, only You can search for stationary targets such as keeping people a long time without changing positions in offices, restaurants and other locations. Tip authority the city has micro-channel positioning crime by statistics reporters found that in recent years, domestic media reported crimes only due to micro-channel triggered, since there are as many as 49. Where rape highest of 24 cases. Among them, the Ningbo man Jo, use micro-channel continuous raped seven young women; Air Jordan 10 and 17-year-old girl Momou Guangdong Lianjiang, due to micro channel by a group of rogue eye, 14 adolescents to be held hostage to the wilderness, 9 people to gang rape. Shenzhen police cracked by the organization of prostitution cases, the criminals took advantage of the micro-letter search for 'nearby' and, after determining 'source' to send prostitutes to-door service. Reporters learned from the police, Beijing has happened to micro letter positioning as a means of implementation of criminal cases. Strangers Meet friends because micro-channel triggered theft, robbery uncommon, including solicitation stranger to black cafe forced high consumption and other cases. Since the Chaoyang Court accepted most of these cases, rape, extortion, robberies have occurred yesterday, reporters will explain the test report and mathematics experts to the Chaoyang Court. Understand the situation, Chaoyang Court very seriously. Assistant Chaoyang Criminal Court Second Chamber Judge Li Jiali think, micro-channel positioning latent crime risk. Micro-channel users should strengthen self-protection awareness, prudent use of positioning, careful to disclose their status or outgoing message, is also not free to accept friend requests from strangers nearby. Police also suggest to pay attention to personal privacy and security, do not give the bad guys an opportunity. The company claims to worry about revealing personal information can close this morning, reporters and staff of micro-channel operator to get in touch. The other said, if you worry about the 'people in the vicinity' feature will disclose your personal information, you can close it. Opened this user functions, you can click the top right corner of the page, and then select Clear location information and exit options, the software will clear the displayed distance information.
