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 ...
On A Relation Between Two Absolute Summability Methods
(
Qatar University
, 1997 , Article)
In this paper we prove a theorem concerning a relation between the summability methods |R,pn,qnlJt and |R,un|fc , k > 1 , which generalizes a result of Bor [2].
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 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 ...
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 ...
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.
New switching algorithm for combining new multi-step CG and self-scaling VM algorithms for non-linear optimization
(
Qatar University
, 1997 , Article)
New interleaved CG and self-scaling VM algorithm is presented in this research which combines Al Bayati's self-scaling VM algorithm with another new multi-step CG algorithm with inexact line searches (ILS). In an interleaving ...
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 ...
