The analysis of the temperature field of caving face is a main step to solve the heat disaster in mine. A mathematical model of air flow and heat trasferation in caving face was set to simulate the distribution law of the temperature field of caving face and the air returning corner. And the simulation result was compared with the data measured in mine. SIMPLE arithmetic which is based on staggered...
Saving data to 2-dimensional adjacent tables which are in memory or to database are adopted by most schemes when maintaining topology data dynamically. However, the adjacent tables would consume significant cost of the memory. Plus, network administration would have to do redundant and repeating work to compile the topology if services are rebooted, which would be absolutely inconvenient and ineffective...
In order to improve the filter accuracy for the nonlinear error model of strapdown inertial navigation system (SINS) alignment, Unscented Kalman Filter (UKF) is presented for simulation with stationary base and moving base of SINS alignment. Simulation results show the superior performance of this approach when compared with classical suboptimal techniques such as extended Kalman filter in cases of...
