New switching algorithm for combining new multi-step CG and self-scaling VM algorithms for non-linear optimization
(
Qatar University
, 1997 , Article)
New interleaved CG and self-scaling VM algorithm is presented in this research which combines Al Bayati's self-scaling VM algorithm with another new multi-step CG algorithm with inexact line searches (ILS). In an interleaving ...

On the direct problem and scattering data for a singular system of differential Equations with discontinuous coefficients
(
Qatar University
, 1996 , Article)
A system of Sturm-Liouiville differential equations of order n with a density matrix function is considered. The direct problem of the considered system is studied and hence the scattering data of the problem is obtained.

Functions Near Of Na-Continuity
(
Qatar University
, 1989 , Article)
In 1986, the concept of Na-continuity was initiated by Chae et al., this leads us to introduce two classes of functions, namely strongly Na-continuity and weakly Na-continuity. We characterize these new types. Several ...

On a mixed boundary value problem for elliptic equations
(
Qatar University
, 1988 , Article)
In this work, a general form of linear and quasilinear elliptic equations is considered. In the presence of boundary singularities, some estimations for the error, according to the net method, are obtained.
