Investigation on Scaled CG-Type Algorithms for Unconstrained Optimization
Abbas Y. Al-Bayati, Khalil K. Abo, Salah G. Shareef,
In this paper, we describe two new algorithms which are modifications of the Hestens-stiefl CG-method. The first is the scaled CG-method (obtained from function and gradient-values) which improves...

Latin Character Recognition using Neural Networks
Jamal S. Majeed, Aseel Ali, Amar S. Majeed
The aim of this work is to recognize the printed Latin's characters. In this work two methods for constructing the feature space are used. These methods are Variance and Fractal dimension methods,...
Curtain Coating Flow of an Inclined Thin Liquid Films
Faraidun K. Hama Salh,
The mechanism of thin liquid films on solid surfaces is fundamental to a wide variety of phenomena such as surface coatings in paint. A mathematical model is constructed to describe the two...
Speech Compression using Wavelet Transforms
Khalil I. Al-Saif,
In this research wavelet technique was used for speech compression. It was translated and scaled to groups which represent mother wavelet function. Applying the adopted algorithm with MATLAB...

w-Wiener Polynomials for Width Distance of Some Special Graphs
Ali A. Ali, Asma S. Aziz,
Let G be a k0-connected graph ,and let ,,be the w- width, distance between the two vertices u,v in G. The w-Wiener polynomial of the width distance of G is defined by: Ww(G;x) is obtained in...
Wiener Polynomials for Multi-Rings Paraffin Structures
Ahmed M. Ali,
The distance between any two vertices u and v in a connected graph G is defined as the length of the shortest path between them, and it is denoted by d(u,v).The sum of distances for all unordered...
The Numerical Range of 6 Χ 6 Irreducible Matrices
Ahmed M. Sabir,
In this paper, we consider the problem of characterizing the numerical range of 6 by 6 irreducible matrices which have line segments on their boundary.
