This paper uses genetic algorithm to optimize the relevance vector machine algorithm to extract the characteristic vector of fault classification, and by contrasting with relevance vector machine, the support vector machine and BP neural network method, it is know that the relevance vector machine optimized by genetic algorithm (ga) can more accurately classify the fault type of conclusion.
With the help of a dynamic mathematical model, the differential pressure across the waterwall in a PFBC (pressurized fluidized bed combustion) boiler is analyzed under abnormal conditions. The simulation tests have shown that the differential pressure will exceed design specification when the bursting diaphragm at the outlet pipe of the freeboard is ruptured and its capacity is larger than 50% of...
The dynamics of solids mixing in a fluidized bed is investigated. Both radial mixing and vertical mixing are taken into account. In the model solids, which consist of an upward moving wake phase (W) and a downflowing emulsion phase (E), can exchange between the two phases, and diffuse in the E phase. Also, properties of bubbles, solids diffusion coefficient and drift velocities are variable along...
