A Special System Of Boundary Value Problems
(
Qatar University
, 1987 , Article)
In this paper we introduce a special system of boundary value problems and give a method for solving it. Then we give a detailed application of this method to a system of boundary value problems of Hilbert type.
Lumping Processes of Periodic ARMA Processes
(
Qatar University
, 2004 , Article)
In this article various lumping processes are defined for periodic ARMA (PARMA) processes, namely, the forward, the backward and the cyclic lumping processes. The inter-relations between the parameters of these lumping ...
On Finite Group Actions On The Solid Klein Bottle
(
Qatar University
, 1989 , Article)
In this paper we classify all G-actions on the solid Klein bottle when G= Z2 and when G= Z^ ® Z2.
A 6th-order local approximation by a cubic curve
(
Qatar University
, 1997 , Article)
We derive and present a MAPLE program for the construction of a parametric cubic polynomial curve which has sixth-order contract with a given smooth curve at a given point, thus providing a local sixth-order approximation ...
A Problem In Thermoelasticity With Two Relaxation Times For An Infinite Thermoelastic Layer
(
Qatar University
, 1995 , Article)
The problem of a ihcrmoclastic layer of finite thickness and infinite extent is considered within the context of the theory of thcrmoclasticity with two relaxation times. The upper surface of the layer is taken as stress ...
Collineations Of Polar Spaces
(
Qatar University
, 1990 , Article)
In this paper we consider general embeddable polar spaces with Witt index at least three.
If π : S( ξ) —> S( ξ’) be a thick collineation between polar spaces with i( ξ) =i( ξ’) ≥3. Then there exists a place Ø: k—> k' U ...
On the solution of Bicriterion Inter Nonlinear fractional programs with fuzzy parameters in the objective functions
(
Qatar University
, 2001 , Article)
In this paper we consider bicriterion integer nonlinear fractional programs having fuzzy parameters in the objective functions. For such programs, a solution algorithm is described to solve the formulated model. The results ...
A Problem In Magneto-Thermoelasticity For A Hollow Circular Cylinder With Thermal Relaxation
(
Qatar University
, 1997 , Article)
The problem of an infinitely long annular cylinder whose inner surface is thermally insulated and whose outer surface is kept at a constant temperature is considered in the presence of an axial uniform magnetic field. The ...
A Numerical Solution For The Bending Of A Plate Using The Boundary Element Method
(
Qatar University
, 1992 , Article)
In this paper the numercial solution for the bending of a plate is considered. The method used is called the Boundary Element Method (BEM). The BEM is a numerical method based on the boundary integral equation formulation ...
Gravitohydrodynamic Instability Of A Streaming Fluid Cylinder
(
Qatar University
, 1996 , Article)
The capillary-gravitodynamic instability of a self-gravitating fluid cylinder (radius R«) dispersed in a self-gravitating medium of negligible motion has been developed. General stability criteria are derived, upon utilizing ...
