The ability of high-fidelity computational fluid mechanics simulation to quantitatively predict the influence ground roughness on evolution wake a three-bladed horizontal axis wind turbine model is tested by comparison with tunnel measurements. approach consists implicit approximate deconvolution large-eddy formulation Hickel et al., (2006), that is, for first time, combined wall-stress flow ov...

Cut-off grade is an important conditioning parameter that determines the quantity and quality of recoverable reserves development efficiency. Today, Russian mining companies operate with certified requirements. By setting permanent requirements, government seeks to prevent depletion reserves, reduced production during periods falling prices, decreased budget revenues, expressing interests all m...

Abstract The Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) is considered among the most frequently used techniques deal with multi-criteria group decision-making (MCGDM) conflicts. In this article, we have presented an extended TOPSIS technique in framework of interval type-2 trapezoidal Pythagorean fuzzy numbers (IT2TrPFN). We first projected a novel approach evaluate...
