Intervals of the parameter λ are determined for which there exist positive solutions for the system of nonlinear differential equations, u(n) + λa(t)f(v) = 0, v(n)+λb(t)g(u) = 0, for 0 < t < 1, and satisfying three-point nonlocal boundary conditions, u(0) = 0, u(0) = 0, . . . , u(n−2)(0) = 0, u(1) = αu(η), v(0) = 0, v(0) = 0, . . . , v(n−2)(0) = 0, v(1) = αv(η).

We investigate the relation between interior-point algorithms applied to two homogeneous self-dual approaches to linear programming, one of which was proposed by Ye, Todd, and Mizuno and the other by Nesterov, Todd, and Ye. We obtain only a partial equivalence of path-following methods (the centering parameter for the first approach needs to be equal to zero or larger than one half), whereas co...

Kentler, dünya üzerinde tüm insanlara kaliteli ve konforlu ya?am alanlar? sunmaktad?r. H?zl? bir art?? gösteren nüfus, ekonomik, sosyal teknolojik geli?meler; kentlerde baz? olumsuz etkiler göstermektedir. K?rsal alanlardan kentlere ya?anan göçler sonucunda; artan nüfus plans?z kentle?me, iklim de?i?ikli?ine neden olarak fiziksel çevreyi insan ya?am?n? tehdit etmektedir. Bu etkilerin ortadan ka...
