Accurate modelling of a chip is a very important factor when analysing and predicting radio-frequency (RF) receiver sensitivity. Chip modelling based on the tangential electromagnetic (EM) field from the near-field measurement just above the top surface of the chip is introduced, and a methodology utilising three-dimensional (3D) EM simulation, for predicting receiver sensitivity generated by the...
To preoccupy the market faster than the competitors and establish the marketing strategy to satisfy the consumers' needs, companies focus on making their best efforts for cost reduction, which is one of the most influential key to the operation. In manufacturing companies, the logistics cost is varied in the range of the product types, methods and situational surroundings. But because of the world-wide...
Active vibration control of the feed support system based on Stewart platform is essential for successfully constructing a Five-hundred-meter Aperture Spherical Telescope (FAST). A flexible control scheme based on RtLinux is proposed and verified in this paper. Considering the weight, volume and precision requirements of the control system, a server-client system is designed, together with a PMAC...
