A Mathematical Model Of The Dynamics Of Schistosomiasis
(
Qatar University
, 1996 , Article)
In this work the authors develop a mathematical model for the dynamics of a major helminth parasite of man, schistosomiasis. The model is a system of coupled non-linear equations. Numerical experimentations with the model ...
Investigation Of Single-Update Memoryless Cg-Methods
(
Qatar University
, 1996 , Article)
Two new CG-methods are proposed in this work for nonlinear unconstrained optimization problems which are considered as memoryless Variable Metric (VM) methods. They are derived for the inexact line searches and evaluated ...
On A Kp Class Of Partial Differential Equations Conservation Laws And Solitary Wave Solutions
(
Qatar University
, 1996 , Article)
It is shown that a KP class of partial differential equations possesses an infinite number of conservation laws. In addition, exact and explicit solitary wave solutions are constructed for the KP class of equations, which ...
Diffusion Problems Arising In Mathematical Biology 2
(
Qatar University
, 1996 , Article)
In this paper we consider long range diffusion, examine the local behavior of epidemics in Lp'q. In section 1 of chapter 2 we develop a model, the long range diffusion pressure in planktonic patchiness and then in secion ...
A Markov Chain Model For River Flow
(
Qatar University
, 1996 , Article)
This paper is concerned with a trinary transformation of river flow. The transformed flow is modeled as a three-states Markov chain and both upcrossing and downcrossing problems are studied simultaneously. The stationary ...
Morphisms Of Affine Schemes And Equivalence Of Categories
(
Qatar University
, 1996 , Article)
In this work we construct the relation between the category R-filt (G(R)-gr) and the category O^ — Filt(O^ — Gr).
The quantum (ungraded) version of this result can be obtained by restricting to parts of zero degree. ...
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 ...
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.
