Krein's method for solving the integral equation of the first kind With logarithmic kernel
(
Qatar University
, 1993 , Article)
Consider the Fredholm's integral equation of the first kind with logarithmic kernel K(IXI) = (- In Ixl. The aim of this paper is to establish the equivalence of Krein's method of solving the equation with the following ...
Stochastic Classes Of Life Distributions
(
Qatar University
, 1990 , Article)
The concept of stochastic ordering of random variables is used to characterize the behaviour of the life length variables. This leads to some new classes of ageing namely, the stochastic classes of life distributions. The ...
A rational logarithmic model for unconstrained non-linear optimization
(
Qatar University
, 1997 , Article)
A new non-quadratic model is proposed for solving unconstrained optimisation problems which modifies and develops the classical conjugate gradient methods. The technique has the same properties as the classical conjugate ...
Explicit Forms of Conservation Laws of a Class of Differential Equations
(
Qatar University
, 1994 , Article)
Explicit forms of conservation laws of a class of nonlinear partial differential equations are derived; firstly from BScklund transformation and secondly from the. fundamental equations of the corresponding inverse method.
Conditionally Exponential Convex Functions On Locally Compact Groups
(
Qatar University
, 1993 , Article)
The main objectives of this study are:
1) The construction of a compact base for the convex cone of all conditionally exponential convex functions.
The determination of the extreme parts of this cone.
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 ...
On estimates of the rate of convergence In the global limit theorems for Homogeneous markov chains
(
Qatar University
, 1997 , Article)
In this paper some estimates are obtained for the remainder term in the limit theorems for the weighted sum of random variables forming a homogeneous Markov chain with arbitrary set of possible states . The achieved results ...
Improvement Of The Piecewise Approximation Methods
(
Qatar University
, 1996 , Article)
A piecewise approximation method is described for planar curves. The order of classical piecewise approximations is improved. The method exploits the freedom in the
choice of the parametrization and rises the approximation ...
Decomposition of a Special Type of Machines
(
Qatar University
, 1994 , Article)
In this paper, the concept of a finite n-state cyclic machine An is defined. These machines are then completely characterized using the prime factorization of n. Specifically, it is proved that any finite-state cyclic machine
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 ...
