While solving practical problems, we often come across situations where the system involves fuzziness. The mathematical models resulting in partial differential equations, involve fuzzy parameters and variables. In ...

Multi-variable nonlinear fuzzy optimization problem is considered under linear order relation on fuzzy numbers. Using gH-differentiability of a fuzzy-valued function ˜ f , new necessary and sufficient optimality conditions ...

In this paper, we find a non-dominated solution of a fuzzy maximum-return problem (unconstrained single-variable fuzzy optimization problem). We establish Newton method to find the solution of the unconstrained single-variable ...

The cotton fiber reinforced polyester composites were fabricated with varying amount of graphite fillers (0, 3, 5 wt.%) with a hand lay‐up technique. Wear tests were planned by using a response surface (Box Behnken method) ...

A new gradient reversed-phase liquid chromatographic method was developed for the simultaneous determination of Esomeprazole, Venlafaxine HCl and Fenofibrate in water. The chromatographic separation of these analytes was ...

In centrosymmetric molecules, like An+[M(CN)6]n− (where A is alkali metal cation), normally all stretching vibrations of cyanide (CN–) shift to high frequency in response to nonhydrostatic pressure, whereas, in non-centrosymmetric ...

In this article, the golden section is related with equilateral triangle and golden hexagons. Simple construction method for making golden ratio hexagon is presented from equilateral triangle with golden sections on each ...

Elasticity solution is obtained for stresses in rings with eccentric holes in bipo-lar coordinate system. The ring is subjected to internal/external pressure at in-ner and outer boundaries. Materials of the cylinder is ...

For practical system operation, for the satisfactory operation of the system at a particular operating condition, it is important to make sure that the system operates with adequate level of security. Security defines as ...
