In the present study, multi-objective optimization of Forward-Curved (FC) blade centrifugal fans is performed in three steps. In the first step, Head rise (HR) and the Head loss (HL) in a set of FC centrifugal fan is numerically investigated using commercial software NUMECA. Two meta-models based on the evolved group method of data handling (GMDH) type neural networks are obtained, in the secon...

Climate change is linked with in precipitation, evapotranspiration, and other climatological parameters, therefore the runoff of a river basin will be affected. The Gomati River largest Tripura. increased settlement climate may threaten natural flow patterns that enable its diversity. This study assesses impact on total from catchment northeast India (the catchment). For this assessment, Group ...

Abstract Free overfalls are hydraulic structures used in flood control, water supply, irrigation, and flow measurements. The systems of free overfall depend on rectangular end shape. studies that dealt with triangular crest few almost non-existent. In this study, a end-shape design uses multiple linear regression (MLR) group method data handling (GMDH) methods for four models six sub-models. Th...

Characteristics of the existing neural networks GMDH with active neurons are given and their main advantages disadvantages analyzed. Two approaches increasing efficiency inductive construction complex system models from statistical data based on a new hybrid using methods computational intelligence proposed. The effectiveness these is compared classical to artificial modelling tasks (noisy line...

The focus of this research is to introduce the application polynomial neural network group method data handling (GMDH) for first time in regional area New South Wales state Australia. Within context, temperature are modeled assess its projected variation impacts on rainfall depth due climate change. study encompasses six local government areas within state’s Central West region. Stochastic meth...
