Some Inferential Problems in Finite Population Sampling
(
Qatar University
, 2004 , Article)
We review some results in problems of estimating a finite population total (mean) through a sample sur¬vey. Section 2 considers inference under a fixed population model and Section 3 addresses the same prob¬lem when the ...
Common fixed Points for Multimaps in Menger Spaces
(
Qatar University
, 2007 , Article)
The aim of this paper is to obtain a common fixed point theorem for multivalued mappings in Menger spaces. Of course this is a new result in Menger spaces. 2000 Mathematics Subject Classification: 47H10, 54H25.
Comparative Growth Performance and Feed Utilization of Four Local Strains of Nile Tilapia (Oreochromis niloticus L.) Collected From Different Locations in Egypt
(
Qatar University
, 2003 , Article)
Brood stocks of Nile tilapia (Oreochromis niloticus L.) were collected from Lakes ofNasser (Aswan), Manzalah, Maryut and Abbassa fishponds. Fingerlings ofFI of each strain was fed diet containing 27% CP for 90 days. The ...
Application of the Forward Modelling of Sequence Stratigraphy & Diagenesis to The Upper Cretaceous Carbonates Of Western Iraq
(
Qatar University
, 2000 , Article)
Dynamic forward modelling of carbonate diagenesis and sequence stratigraphy relies on the understanding of the different process which provide a high resolution prediction of the geometry of porous and permeable zones ...
The Optical and Electrical Properties of Low Density Polyethylene Films in CuSo4 Solution
(
Qatar University
, 2005 , Article)
The optical and electrical properties of pure and treated low density polyethylene (LDpE) were investigated. These measurements have been carried out at various times of immersion for LDPE films in 10% solution of CuSO+. ...
Cleavability of Decomposition Spaces
(
Qatar University
, 2006 , Article)
Assume that X and Y have the same homotopy type, if X (respectively Y) is cleavable over p, have proved that the decomposition space of Y/g (respectively X/f) is cleavable over p. A result ncerning Arhangel'skii - Teroni's ...

(
Qatar University
, 2006 , Article)
Night and early morning flying insects in Doha were recorded daily, for a complete year, using a light-water trap. Two peaks of insect numbers occurred in April-May and September-October periods respectively. The lowest ...
Performance Analysis of a Fileserver in an ATM Network
(
Qatar University
, 2004 , Article)
ATM continues to gain acceptance as a unifying communications technology for traffic of both digital and analog origins. The main characteristic of an ATM network is its discrete time (slotted) operation and fixed-length ...

An attempt has been made to examine the relative stabilities of Z, center orientations at the surfaces of
Be2+, Mg2+ and Ca2+ doped LiCl, NaCl and KC1 ionic crystals as well as the effects of Z, center on the
adsorption ...
Algebraic Approach to Formal Microstructure Sheaves and Formal Quantum Sheaves Over Projective Schemes
(
Qatar University
, 2007 , Article)
The I-adic non-commutative filtrations have crucial applications in the study of Lie algebras and the integral group rings. The I-completion R of a commutative ring R is considered a useful tool in algebraic geometry. Here ...
