in this paper, a novel approach for ranking fuzzy numbers based on the angle measure is introduced. several left and right spreads at each chosen levels of fuzzy numbers is used to determine center of mass points(cmps) and then, the angels between the cmps and the horizontal axis is calculated. the total angle is determined by averaging the computed angles and finally, the novel method is compa...

The rotor is one of the vital components a wind turbine. In design rotor, expected result most optimal power. This purpose study to optimization Horizontal Axis Wind Turbine power various parameters such as airfoil, angle attack, and pitch angle. Airfoils (NACA 4412-2412 T.E. mod, NACA 2412-4412 L.E. mod), attack (0, 2, 4, 6), 1, 3) are parameter variations used. simulation method uses BEM (Bla...

PURPOSE To report a case of choroidal effusion probably caused by angiotensin receptor II blocker. CASE REPORT A 52-year-old man with aplastic anemia and high blood pressure who developed unilateral acute angle closure glaucoma after receiving oral cyclosporine and angiotensin II receptor blocker (losartan). Ophthalmic examination revealed visual acuity of 20/30 in the left eye, mild mydriasi...

The purpose of the study is to estimate the optimal release conditions for male and female world discus record holders of 1998 under no wind and in the wind. The estimation was achieved by using numerical methods to deal with the lift and drag coefficients in Ganslen’s wind tunnel tests of discus. The results showed that under no wind, when the release height of both male and female holders was...

Abstract The computational model designed for studying the processes of non-equilibrium physicochemical gas dynamics in supersonic rarefied-air flow past a blunt plate finite dimensions under laboratory experiment conditions is formulated. based on two-dimensional Navier–Stokes equations, energy conservation laws translational degrees freedom atoms and molecules vibrational diatomic molecules, ...

VIV model test results are presented for a bundle of three parallel pipes all lying in the same plane, similar to a riser with large kill and choke lines. The rigid model was attached to a spring-mounted frame in the MIT towing tank. The horizontal model was towed in the tank and allowed to respond in free vibration to vortex-induced vibration in the cross-flow direction. The angle of attack of...
