Filtered Dehomogenization Theory For The Micro-structure sheves OY
(
Qatar University
, 1999 , Article)
In this work we study the theory of dehomogenization at the level of filtered sheaves using the micro-structure sheaves. For the sheaf of quantum section the results are still true.
S — Compactness Via Ideals
(
Qatar University
, 1991 , Article)
Compactness modulo as an ideal has not been widely studied. Many new sorts of weak compactness have been introduced to topological spaces in the last twenty years but have not been studied using ideals. So, the main aim ...

A Short Note On The Point-Wise Summability Of The Conjugate Series Of A Fourier Series In The Norlund Sense
(
Qatar University
, 1985 , Article)
In this note we consider an analogous theorem of [l] in the sense of point-wise summability of the conjugate series of a Fourier series in the Norlund sense
Two Forms Of The Backlund Transformation Of A Third Order Differential Equation
(
Qatar University
, 1996 , Article)
Two explicit forms of Backlund transformation of third order dispersive differential equation are derived. The method of derivation depends on the use of a transformation that couples the equation with its modified one.
Gravitational Instability of a Radiating Gas Cloud with Variable streams
(
Qatar University
, 2001 , Article)
The self-gravitating instability of a radiating gas cloud possessing variable streams is investigated. The self-gravitating force is destabilizing according to restrictions, the radiation has a strong stabilizing influence ...
Approximating the Distribution of Quadratic Forms Using Orthogonal Polynomials
(
Qatar University
, 1999 , Article)
In this paper we propose some techniques to approximate the distribution of quadratic forms in normal random variables. The first two techniques will be based on orthogonal polynomials, namely; the Hermitte and Laguerre ...
Krein's method for solving the integral equation of the first kind With logarithmic kernel
(
Qatar University
, 1993 , Article)
Consider the Fredholm's integral equation of the first kind with logarithmic kernel K(IXI) = (- In Ixl. The aim of this paper is to establish the equivalence of Krein's method of solving the equation with the following ...
Stochastic Classes Of Life Distributions
(
Qatar University
, 1990 , Article)
The concept of stochastic ordering of random variables is used to characterize the behaviour of the life length variables. This leads to some new classes of ageing namely, the stochastic classes of life distributions. The ...
A rational logarithmic model for unconstrained non-linear optimization
(
Qatar University
, 1997 , Article)
A new non-quadratic model is proposed for solving unconstrained optimisation problems which modifies and develops the classical conjugate gradient methods. The technique has the same properties as the classical conjugate ...
