Variance Estimation for Poverty Indicators via Linearization Technique
(2018-08-24)In this study, an assessment of precision of poverty indicators is made with a view to improving its performance. A multiplicative bias reduction density function is used in estimating the poverty indicators and compared ... -
Variance Estimation in Stratified Random Sampling in the Presence of Two Auxiliary Random Variables
(International Journal of Science and Research, 2014)The objective of this paper is to develop an improved population variance estimators in the presence of two auxiliary variables in stratified random sampling adapting the family of estimators proposed by Koyunchu and ... -
Velocity Profiles of Unsteady Blood Flow through an Inclined Circular Tube with Magnetic Field
(Journal of Advances in Mathematics and Computer Science, 2017)The present paper is devoted to study the flow of incompressible viscous, electrically conducting fluid (blood) in a rigid inclined circular tube with magnetic field. The blood is considered to be Newtonian fluid and the ... -
Wide visible emission and narrowing band gap in Cd-doped ZnO nanopowders synthesized via sol-gel route.
(Elsevier Ltd., 2016)Cd doped ZnO nanopowder (Zn1−XCdXO, 0.15≤ X ≤0.45) has been synthesized by facile sol-gel method. The X-ray diffraction (XRD) shows the powder possess polycrystalline with hexagonal wurtzite structure of ZnO without formation ... -
(μ-Ethane-1, 2-diamine-κ2N: N′) bis [dicarbonyl (η5-cyclopentadienyl) iron (II)] bis (tetrafluoridoborate)
(International Union of Crystallography, 2011)The asymmetric unit of the title compound, [Fe2(C5H5)2- (C2H8N2)(CO)4](BF4)2, contains two half-cations, each located on a center of symmetry, and two tetrafluoridoborate anions. The iron atoms adopt a three-legged ... -
(μ-Formato-κ2O: O′) bis [dicarbonyl (η5-cyclopentadienyl) iron (II)] tetrafluoridoborate
(International Union of Crystallography, 2011)In the structure of the title compound [Fe(2)(C(5)H(5))(2)(CHO(2))(CO)(4)]BF(4), each Fe(II) atom is coordinated in a pseudo-octa-hedral three-legged piano-stool fashion. The cyclo-penta-dienyl ligand occupies three fac ...
