Schistosomiasis is a parasitic disease mostly found in areas along the Changjiang River, Oncomelanias is the only intermediate host of schistosomiasis. Oncomelania entering into farmland or the residential zones through the flood discharge or irrigation system is the main reason of spreading schistosomiasis. Therefore it is most essential and effective way to control diffusion of oncomelanias a...

Abstract Energy dissipation is one of the important issues in piano key weirs (PKWs). Excessive energy at weir's toe can cause scouring. In previous studies, arced (APKWs) has not been investigated. this experimental study, effect weir height as well and arrangement baffles located on outlet slope amount dissipated were examined trapezoidal (TPKWs) APKWs. Experiments performed models with two t...

the control of hydraulic jump through thin-crested sills in a trapezoidal channel was studied theoretically as well as experimentally. the experiments were conducted in a specially designed stilling basin for 1:1 side slope. the results show that for a given side slope, end sill increases the stability of the jump within the stilling basin. it also causes a 13-15 percent reduction in the length...

In this paper, a new concept called Trident Fuzzy Aggregation Operators in which the operation is made by grouping of numerous Trapezoidal Numbers (TTriFN) to become solitary trapezoidal trident fuzzy numeral for parallel computing application introduced. This proposed operator architecture applicable development networking and ranking concepts. Also, geometric mean over ‘n’ TTriFN on left-side...
