Weiner Polynomials for Generalization of Distance for Some Special Graphs
Ahmed M. Ali, Ali Aziz Ali,
The minimum distance of a vertex v to an set of vertices of a graph G is defined as : . The n-Wiener polynomial for this distance of a graph G is defined as , where is the number of order pairs...
Numerical Solution of the Problem of Heat Transfer by Convection
Ahmed M. Juma’a, Ashraf S. Aboudi,
In this paper we have presated a heat transfer by convection in rectangular cavity filled with static fluid. Differentially heated end vertical walls. Two-dimensional motions are assumed. The...

Ayad M. Ramadhan, Adil K. Jabbar
In this paper, the problm of sequencing n jobs on one machine is considered with a multi objective function.Two problems have been studied, sum of completion times added with the maximum tardiness...
EPS & EPUS Step-size Control for Linear Multistep Method
Abbas Y. Al-Bayati, Ann J. Al-Sawoor, Abbas H. Taqi,
In this paper we consider step-size control in one class of Adams linear multi-step methods for Ordinary differential equation. Theoretical results are presented for Adam-Bashforth-Moulton formula...
On the Generalized Curvature
Tahir H. Ismail, Ibrahim O. Hamad,
By using methods of nonstandard analysis given by Robinson, A., and axiomatized by Nelson, E., we try in this paper to establish the generalized curvature of a plane curve at regular points and at...
A Crank-Nicolson Method of Autocatalytic Reaction-Diffusion Systems
Abbas Y. Al-Bayati, Saad A. Manaa, Abdulghafor M. Al-Rozbayani,
In this paper we used two numerical methods to investigate propagating heat solutions of PDEs. The explicit and Crank-Nicolson methods and the results show that Crank-Nicolson method is more...
Comparison of Edge Detection Methods in Gray Images
Sobhi H. Hamdoun, Afzal A. Hassan,
The methods of edge detection play an important role in many image processing applications as edge detection is regarded as an important stage in image processing and the extraction of certain...
A Generalization of A Contra Pre Semi-Open Maps
Abdullah M. Abdul-Jabbar,
The concept of q-semi-open sets in topological spaces was introduced in 1984 and 1986 by T. Noiri [9, 10]. In this paper we introduce and study a generalization of a contra pre semi-open maps due...
Image Compression Technique Using a Hierarchical Neural Network
Rafid A. Khalil, Mohammed C. Younis,
This paper present a Resilient Backpropagation (RBP) algorithm based on hierarchical neural network for image compression. The proposed technique includes steps to break down large images into...
Stability Analysis of Fisher Equation Using Numerical Galerkin Techniques
Saad A. Manna, Ahmed F. Qassem,
We studied the stability of the steady state solutions for Fisher Equation in two cases, the First one with constant amplitude and we show that the steady state solution is always stable under any...
Encryption Binary Images by Using Template Matching
Sundus Khaleel Ebraheem,
Text encryption is a very important field in application of data transformation through the digital networks, and the Internet, so it is very necessary to do encryption operation on the text data...
On Rings Whose Principal Ideals are Pure
Shaimaa Hatem Ahmad,
In this work, we study rings whose every principal ideal is a right pure. We give some properties of right PIP rings and the connection between such rings and division rings.
Parallel Newtonian Optimization without Hessian Approximation
Khalil K. Abbo,
The purpose of this paper is to introduce parallel algorithms based on the Newton method for solving non-linear unconstrained optimization problem in (MIMD) parallel computers by solving linear...
A Hyperbolic Rational Model for Unconstrained Non-Linear Optimization
Nidhal H. Al-Assady, Basim A. Hassan,
We consider a class of invariant Hyperbolic scaling of a strictly convex quadratic function, to extend the family of the conjugate gradient methods for solving unconstrained minimization problems....
Compression of Satellites Images Using Embedded Zero Tree Wavelet
Ahmed Kh. Al-Selifani, Faten A. Mustafa,
The compression technique is an optimal solution for decreasing the amount of information sents out from satellites to earth station with rate transmission. In this paper, a study for the...
