in this paper, we introduce a takagi-sugeno (ts) fuzzy model which is derived from a typical multi-layer perceptron neural network (mlp nn). at first, it is shown that the considered mlp nn can be interpreted as a variety of ts fuzzy model. it is discussed that the utilized membership function (mf) in such ts fuzzy model, despite its flexible structure, has some major restrictions. after modify...

The inhibition effect of rapid variations pH in wastewater on activated sludge was investigated laboratory-scale sequencing batch reactors (SBR). toxic influence 6.5 and 8.5 examined. experiment with preferable to formation high FA concentration showed a low risk second step nitrification (conversion nitrites nitrates). However, the reactor at first-step ammonia nitrites) caused by FNA formatio...
