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 ...
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 ...
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 ...
Theory and Computations for Systems Modeled By First Order Differential Equations
(
Qatar University
, 2000 , Article)
A numerical scheme using Sine functions is developed to approximate the solution of a 2 x 2 system of first order differential equations. The error in the approximate solution is shown to converge exponentially.
An Extension of the Szasz-Mirakyan Operator on the Whole Real Axis
(
Qatar University
, 2000 , Article)
The aim of this paper is to present a new extension of the Szasz-Mirakyan operator n the whole real axis, and to give its convergent approximation theorem.
Strong and Weak n-Homogeneous Spaces
(
Qatar University
, 2004 , Article)
In this paper we introduce new types of n-homogeneity, we call them n-homogeneous of type 2 and type 3, denoted by nH2, nH3 respectively. We show that every 3H3-space is bihomogeneous space. Also, every finite nH3-space ...
S.G. Connected Spaces
(
Qatar University
, 2000 , Article)
The purpose of this paper is to introduce and study a strongr type of connectedness called s.g connectedness in topologi-cal spaces.
A Random Binary Trees Generation Method
(
Qatar University
, 2000 , Article)
There are two widely used random distributions on binary trees, namely the binary search tree distribution and the uniform distribution. By analyzing the performance of algorithms that manipulate binary trees generated at ...
Fixed Point Theorems in Topological Spaces
(
Qatar University
, 2000 , Article)
A couple of theorems for a pair of self-maps on a topological space have been obtained using which certain fixed point theorems in the literature for pairs of maps satisfying contractive type conditions have been deduced.

A Rational Exponential Model for Unconstrained Non-Linear Optimization
(
Qatar University
, 2002 , Article)
In this Paper, a new algorithm based on the non-quadratic model is suggested for solving unconstrained optimization problems which modifies the classical conjugate gradiant methods. This technique has the same properties ...
