On The Behaviour Of The Solutions Of ff …...
(
Qatar University
, 1984 , Article)
The above equation plays an important rote in the geometric theory of functions of a complex variable.
To determine interval estimations for its solutions, an inequality is obtained using the fixed point theorem. Then, ...
A Family Of Nonramified Functions, Defined In Zz<1
(
Qatar University
, 1983 , Article)
In this article a family of nonramified functtions, defined in zz<l, is obtained. It is characterized by an achieved distortion theorem; its Bloch constant and the limit of convexity are determined. Peschl's principle is. ...
Completeness Of Distributive P-Algebras
(
Qatar University
, 1988 , Article)
According to the triple characterization of distributive p-algebras which is given by T. Katrinak, we characterize the completeness of distributive p-algebras.
The Backlund Transformation Of A Kp-Like Class Of Nonlinear Partial Differential Equations
(
Qatar University
, 1996 , Article)
The Backlund transformation of a class that behaves in a manner similar to that of the Kadometsev-Petviashli is derived via the use of a transformation that couples this class with a modified given class of the same order. ...
On Some Shrinkage Techniques For Estimating The Parameters Of Exponential Distribution
(
Qatar University
, 1986 , Article)
A variety of shrinkage methods have been proposed for estimation of some unknown parameter by considering estimators based on a prior guess of the value of the parameter. We compare some of the shrunken estimators for the ...
Point-Wise Summability Of Fourier Series And Its Related Series In The Norlund Sense
(
Qatar University
, 1985 , Article)
In this note we consider the point-wise summability of Fourier series in the Norlund sense by extending a theorem of Lebesgue [ 6 ] . We also consider analogous theorems of our extension to derived Fourier series, and ...
Generation of Sets of Sequences lsomorphic to Walsh Sequences
(
Qatar University
, 2005 , Article)
Walsh sequences of the order 2k, k positive integer, form an additive group generated by Rademacher sequences set of ft-order. Except the zero sequence, Walsh sequences form an orthogonal set. Our present work allows us ...
دراسة تحليلية لتحديد المفاهيم والمهارات الرياضية اللازمة لتعلم العلوم لطلاب المرحلة المتوسطة ومدى اتقانهم لها.
(
Qatar University
, 1995 , Article)
يؤكد العديد من المتخصصين في طرق تدريس العلوم، وكذا المؤتمرات والبحوث والدراسات على أهمية التنسيق بين الرياضيات والعلوم، كما تؤكد على أن تستقي المشكلات الرياضية من الفروع المختلفة للعلوم الطبيعية.
وبدراسة الأدبيات في مجال ...
Approximate Solution For A Problem Of Propagation Of Elastic-Plastic Wave In The Half-Space
(
Qatar University
, 1984 , Article)
In this paper, we consider a half-space occupying an elastic-plastic medium. Treatments were carried out under the assumption of perpendicular load, on boundary which propagates with a constant speed D.
The assumption ...

(
Qatar University
, 1994 , Article)
This paper is devoted to study the inverse scattering problem of a generalized Sturm-Liouville equation on the whole line.The solutions of the considered problem and their asymptotic behaviour are presented.The expansion ...
