In this paper, Lomb periodogram estimate as a new spectrum calculation approach was used to deal with unevenly sampled signals sampled by Laser Doppler Particle Analyzer in Kenics Static Mixer. The effectiveness of the method was demonstrated by the simulations of deterministic model. The time series of instantaneous velocity in the turbulent region under(More)
—The free swing fire monitor is suitable for the situation which is too risk to access for fireman. The fire monitor control system designed in this thesis has two control modes, wireless remote mode and panel control mode. So fireman can use it far from the dangerous fire field to aim at the fire and make it swing in a certain range. In this system, a MCU(More)
