In this paper, according to users' need, a leakage protector operation regulation plan is put forward, and a whole system function model is established. The whole system design is completed according to the engineering software development request, then an operation regulation system is put forward creatively based on GPRS and PDA. The system is designed briefly and in detail in this paper, the hardware...
A statewide comparison test of wind profiler was held in the southeast of Beijing by China Meteorological Administrator (CMA) from July 26th to October 25th in 2005. The main content includes static test and dynamic comparison. Eight wind profilers which were manufactured by China were tested. Among these, five boundary layer profilers which operate on different frequencies observed simultaneously,...
Wind profiler is a kind of clear air radar, which takes atmospheric turbulence as main detecting object. The electromagnetic wave scattering of atmospheric turbulence is extremely weak, so the turbulence echo will be easily submerged, especially under the condition of precipitation. In order to identify turbulent flow echo and improve the accuracy of the spectra moment evaluation a wind is presented...
This paper considers a group of mobile agents moving in Euclidean space with switched network topology. We propose a feedback control algorithm that achieves velocity consensus with weighted directed switched velocity graph and stabilize all position neighboring agents inter-distance to a same desired value. The main results are that the position and velocity graph remaining connected are satisfied...
