Prediction of syngas compositions, the most important parameter in determining the product's grade and quality control of raw syngas produced in coal gasification process, was studied. A neural estimator model based on improved dynamic principal component analysis (DPCA) and multiple neural networks (MNN) was proposed to infer the syngas compositions from(More)
An analytical model based on modal series expansion method for calculating transmission loss (TL) of compressor’s mufflers has been present in this paper. The approximately averaged pressure response value, obtained by calculating the weighted average pressure response value in the vicinity of the point source, is applied to derive the pressure response(More)
