This study presents energy, entropy, and exergy analyses of Al2O3-Cu/water hybrid nanofluid flow in a trapezoidal cross-sectioned channel under turbulent regime (104<Re<105) for the first time. Understanding main source entropy generation along channel, also obtaining total variation comparing to single nanofluids (Al2O3/water Cu/water) base fluid is pursued objective. In other p...

We have presented trapezoidal intuitionistic fuzzy number. Arithmetic operations of trapezoidal intuitionistic fuzzy number is presented based on (α, β)-cuts. We have presented intuitionistic fuzzy fault tree analysis using trapezoidal intuitionistic fuzzy number. In application of intuitionistic fuzzy fault tree analysis, we have computed failure of fire protection system taking failure of eac...

The Sn(IV) cation in the title compound, [Sn(CH3)2(C10H8NO)2], is N,O-chelated by two 2-methyl-quinolin-8-olate anions and coordinated by two methyl groups in a skew-trapezoidal bipyramidal geometry. In the mol-ecule, the two quinoline ring systems are twisted to one another at 10.91 (18)°. The dimethyl-tin skeleton [C-Sn-C = 149.6 (2)°] is bent over the longer edge of the trapezoid that is def...

As an extension of the intuitionistic fuzzy set, intuitionistic trapezoidal fuzzy set is an invaluable mathematical theory to express uncertain phenomenon in our real word. In this article, the aggregation methods of the intuitionistic trapezoidal fuzzy information are chief researched. Firstly, the generalized aggregation operator is introduced for aggregating intuitionistic trapezoidal fuzzy ...

This paper documents the optimization of architecture in accordance with Bejan’s Constructal theory. For illustration, we consider the optimization of a cavity that intrudes into a solid conducting wall, having internal heat generation and adiabatic conditions on the outer surfaces. The cavity is rectangular, with fixed volume and variable aspect ratio, and the solid is trapezoidal. The objecti...

The Schwarz–Christoffel toolbox, a free MATLAB package for the computation of conformal maps, is applied to the quasi-static analysis of coplanar waveguides (CPWs) of arbitrary cross section in order to provide computationally efficient and very accurate estimates of their capacitance, inductance, characteristic impedance, and skin-effect attenuation. A few examples of many-sided polygonal wave...

Six new 1-benzoyl-3-phenylthiourea and 1-benzoyl-3-(2-methylphenyl)thiourea complexes of mercury(II) were obtained in the reactions of the ligands with HgX2 in methanol (X = Cl, Br, I). Their structures, determined by single-crystal X-ray diffraction analysis, exhibit different stoichiometries and molecular organization. Coordination centers adopt more or less distorted tetrahedral geometry (fi...

A variety of stimulus factors have recently been shown to influence the performance of normal subjects on line bisection tasks (i.e., pseudoneglect), independent of motoric factors such as scanning or hand use [McCourt & Jewell (1999) Neuropsychologia 35, 843-55]. An experiment is described which further examined the modulating influence of line geometry in determining the magnitude of pseudone...
