On The Stability Of Fixed Points In Topological Spaces

Abedal-Hamza Mahdi Hamza, Mohammed Faris Y.

Pages: 11-19 English

Full Text Issues

Abstract

In this papers we introduced new concepts of stability: strongly stable, c-stable, and c-strongly
stable. We discussed the stability of fixed points with respect to each of a topology and a base for that
topology. We obtained that if a fixed point is stable (strongly stable, c-stable, strongly c- stable
respectively) with respect to a base for a topology, then it is stable (strongly stable, c-stable, strongly
c- stable respectively) with respect to that topology.

The Open Limit Point Compactness

Pages: 20-23 English

Abstract

In this paper, we gave a new
topological concept and we called it the
open limit point compactness.We have
proved that each of the compactness, and
the limit point compactness is stronger
than of the open limit point compactness.,
that is, compactness implies open limit
point compactness, also limit point
compactness implies open limit point
compactness, but the converse is not true.
Also we have shown that the continuous
image of an open limit point compact is an
open limit point compact and so this
property is a topological property .This
property is not a hereditary property.
Connected spaces are open limit point
spaces. The one-point compactification of
a space is an open limit point compact.
Finally, we have shown that if is an
open limit point compact, then each of ,
and is an open limit point compact.

Hosoya Polynomials Of Some Semiconducotors

Azeez Lafta Jabir, Abdul Jalil M. Khalaf, Emad A. Jaffar AL-Mulla

Pages: 49-55 English

Full Text Issues

Abstract

The Hosoya polynomial of a graph G is a
graphical invariant polynomial that its first
derivative at x = 1 is equal to the Wiener index
and second derivative at x =1 is equal to the
hyperWiener index. In this paper we compute
the Hosoya polynomial of some
semiconducotors [Caesium Chloride,
Perovskite structure, Zinc blende structure,
Rock-salt(Nacl)structure, Wurtzite structure,
Chalcopyrite structure], Wiener index and
hyper-Wiener index for then.

Abstract

In this paper, we introduce and study a new
class of meromorphic Univalent functions
defined by Dziok_Srivastava operator for this
class. We obtain coefficient inequality, convex
set, closure and Hadamard product (or
convolution).Further we obtain a -
neighborhood of the function , and the
integral transform.

Robust Estimators of Logistic Regression with Problems Multicollinearity or Outliers Values.

Fadhil Abbul Abbas AL- Aabdi, Rafid Malik Atiyah AL – Shaibani

Pages: 64-71 English

Full Text Issues

Abstract

Whenever there is a relationship between the
explanatory variables (
). This relationship
causes multicollinearity which in turn leads to
inaccurate and bias estimations of the model
parameters.
Therefore, this results in high discrepancy that
influences the next phase of the statistical
inference where (OLS), method loses its features
having the lowest variance.
Consequently, this paper concerns itself with
figuring out methods that can be applied by
researchers and those who are interested in this
field to overcome this problem using (Ridge)
method. Moreover, the paper seeks to solve other
problems such as the loss of normal distribution
property or abnormalility by means of methodical
means including (Ridge) and (Robust Ridge).
However this study is applied through simulation
experiments aim at producing the data of the
model. Based on these experiments and tests, the
research has come up with the result that (Robust
Ridge) is the best method that might be employed
to solve the problem of has both normal and
abnormal data for the estimation of the parameters
of the Logistic Regression Model.

An Approach for Solving Missing Values in Data Set Using Clustering-Curve Fitting Technique

Dr. Kadhim AlJanabi, Dr. Mansoor Habeebi, Nawras Riyadh Neamah

Pages: 81-99 English

Full Text Issues

Abstract

Missing values in data sets
represent one of the greatest challenge
in analyzing data to extract knowledge
from the data set. The work in this
paper presents a new approach for
solving the missing values problems by
using and merging two different
techniques; clustering (K-means and
Expectation Maximization) and curve
fitting. More than twenty thousand
records of real health data set collected
from different Iraqi hospitals were
used to create and test the proposed
approach that showed better results
than the most popular techniques for
estimation missing values such as most
common values, overall overage, class
average, and class most common
values. Different software were used in
the proposed work including WEKA
(Waikato Environment for Knowledge
Analysis), Matlab, Excel and C++.
