More and more intelligent functions are proposed, designed and implemented in meters to make the power supply be smart. However, these complex functions also bring risks to the smart meters, and they become susceptible to vulnerabilities and attacks. We present the rat-group attack in this paper, which exploits the vulnerabilities of smart meters in the cyber world, but spreads in the physical world...
By actual measurement, low frequency magnetic field distributions in the multiple unit train were obtained. The data shows that the field is in the permission range as a special industrial environment according to international low frequency magnetic field standards and GB 9175-88. Taken into account of the multiple unit train's specific electrical structures (including overhead contact system, car...
The East China Sea Seafloor Observatory, the Xiaoqushan seafloor observatory which located between 30° 31′44″N, 122° 15′12″E and 30°31′34″N,122°14′40″E, was built on April 21st, 2009. The submarine optical fiber composite power cable is landed on the platform by The East China Sea Branch, State Oceanic Administration of the People's Republic of China, and the power is continuously supplied by the...
A regular representation can be determined for a prism with cross section of biaxial symmetry. Then reduce the regular representation and determine the complete basis.The calculation results show that to describe scattering object surface current with this basis function expansion is of fast convergence speed and high accuracy.
