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 ...
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. ...

The One Dimensional Inverse Spectral Problem Of A Generalized Stationary Schrodinger Equation
(
Qatar University
, 1996 , Article)
In this paper we study the inverse problem on the half line for a generalized stationary one dimensional Schrodinger equation. We consider the solutions of the differential equation and study its properties. Given the ...
The Likelihood Function For A Progressive Disease Model With A Bivariate Survival Function
(
Qatar University
, 1995 , Article)
A model for the natural history of a progressive disease is developed. The model has three disease states and can be expressed as the joint distribution of two survival random variables. Covariate information is incorporated ...
The Adjoint Problem Of A Modified Sturm-Liouville Boundary Value Problem
(
Qatar University
, 1993 , Article)
The authors give the solutions of the eigenvalue equation that is associated with a modified Stum-Liouille problem. The discrete specturm and hence the resolvent will be obtained by means of different types of solutions ...
