The state of algae growth in seawater has great effect to marine entironment, but it is difficult to find a kind of sensor to measure it on line and with real-time. In this paper, a kind of soft sensor built by T-S fuzzy neural network is applied to monitor the reproduction state of algae growth. The content of chlorophyll-a in seawater is regarded as the token factor to describe the state of algae...
A new detection solution was put forward to solve the problem of the rotor unbalance detection on the single-pivot point framed dynamic balancing machine. The detection principle was discussed and the design schemes of software and hardware of the system were proposed. Related parameters were selected for the rotor which is no more than 5Kg and whose working speed is not high. The application results...
