An Approximation Leading To The Binomial Distribution In The Stochastic Treatment Of A Reversible Chemical Reaction
(
Qatar University
, 1992 , Article)
The exact equilibrium distribution of the number of molecules of C in the reversible chemical reaction A+B ^=S: C is shown to converge to the binomial distribution when N is finite,
M—»!K, K—>0 in such a way that KM is ...
A Class Of Functions Stronger Than M-Precontinuity, Preirresolute And A-Functions
(
Qatar University
, 1990 , Article)
We propose a definition for a new class of functions that may be stronger than the previous types. Some of its characterizations, connections with known ones and the effect of them on some topological spaces are studied .
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 ...
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 ...
Bayes Estimation of the Parameter of Burr Type II Distribution in Case of Type II Censoring
(
Qatar University
, 1997 , Article)
Suppose that Xj, X2, ..., Xn is a random sample of failure times from a Burr type II (B2) distribution
with parameter 9. Let x = (xj, x2, , xr) with xj < x2 S x3 < < xr be the observed failure censored
sample of the first ...
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 ...
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 ...
A Mixed Markovian Time Series Model
(
Qatar University
, 1997 , Article)
We study a simple time series model the noise properties of the proposed model are derived. An algorithm based on the conditional mean and the conditional variance, for estimating the parameters of the proposed model is ...
A study on summability factors of infinite series
(
Qatar University
, 1997 , Article)
A new theorem concerning N,p q , summability factors of infinite series are deduced.
Threshold Modelling Of Ship's Dynamics
(
Qatar University
, 1995 , Article)
In this paper we consider an application of a system called threshold system in the field of marine engineering. Properties of this system are discussed and the idea of the impulse response function of threshold system is ...
