In wastewater treatment plants, It's difficult to acquire online data of BOD5 (Biochemical Oxygen Demand for 5 days) due to its characteristic and unreliability of on-line sensors. Furthermore, although soft sensors models are widely used in wastewater treatment, only a few approaches for soft sensors models are designed to address the problems currently existing in the wastewater treatment. In such...
In order to improve the aeroengine mathematic model precision, the Metamodeling methodology was introduced, and three kinds of metamodels of the compressor flow and efficiency characteristics were built, using polynomial regression(PR), radial basis function(RBF) and Kriging methodology. Simulation on the low-pressure compressor of a given turbo-fan engine was carried out as an example, and the characteristics...
