Improving Conjugate Gradient method For Training Feed Forward Neural Networks
Luma.
N. M.Tawfiq
Alaa.
K. J. AL-Mosawi
In this paper, many modified and new algorithms have been proposed for training feed forward neural networks, many of them having a very fast convergence rate for reasonable size networks.
In all of these algorithms we use the gradient of the performance function (energy function, error function) to determine how to adjust the weights such that the performance function is minimized, where the back propagation algorithm has been used to increase the speed of training. The above algorithms have a variety of different computation and thus different type of form of search direction and storage requirements, and all the above algorithms applied in approximation problem.

One Significance Test Estimator for the Shape Parameter of Generalized Rayleigh Distribution
Abbas
Najim Salman
This paper is concerned with preliminary test single stage Shrinkage estimator for the unknown shape parameter () of two parameter generalized Rayleigh (GR) distribution with known scale parameter (), when a prior knowledge about the shape parameter () is available as initial value (0), using shrinkage weight factor () and pretest region R. This prior knowledge about unknown parameter may be obtaind from past experiences or from a quaintance with similar situation.
Expression for the Bias, Mean squared error [MSE] and Relative Efficiency [R.Eff()] for the proposed estimator are derived. Numerical results and conclusions of mentioned expressions are carried out to assess the effects of the considered estimator and to illustrate these results. Tables of these numerical results are demonstrated. Comparisons between introduced estimator with respect to classical estimator and with some existing studies in the sense of mean suqared error or Relative Efficiency are performed.

Let R be a commutative ring with unity .A unitary R-module M is called a quasi-Dedekind module if for all nonzero submodules N of M . In this paper we introduce and study the concept of small quasi-Dedekind module as a generalization of quasi-Dedekind module . Where an R-module M is called small quasi-Dedekind if, for each nonzero homomorphisms f from M to M , implies Kerf small in M ( Kerf ≪ M ). And an R-submodule N of an R-module M is called a small submodule of M (N ≪ M , for short) if , for all K ≤ M with N+K = M implies K = M

In the problem of scheduling a single machine to minimize the sum of completion time and total late work, there are n jobs to be processed for which each has an integer processing time and a due date. The objective is to minimize the sum of total completion time and total late work ,where the late work for a job is the amount of processing of this job that is performed after its due date.
Although dominance rules are derived for the special cases in which all processing times are equal and all due dates are equal. Algorithm H is presented for the general non preemptive sum of completion time and the total late work simultaneous problems

A harvested prey-predator model with infectious disease in prey is investigated. It is assumed that the predator feeds on the infected prey only according to Holling type-II functional response. The existence, uniqueness and boundedness of the solution of the model are investigated. The local stability analysis of the harvested prey-predator model is carried out. The necessary and sufficient conditions for the persistence of the model are also obtained. Finally, the global dynamics of this model is investigated analytically as well as numerically. It is observed that, the model have different types of dynamical behaviors including chaos

An Equation Related To Jordan *-Centralizers

Let R be a *-ring, an additive mapping T: R →R is called A left (right) Jordan *-centralizer of a *-ring R if satisfies T(x2)=T(x) x* (T(x2)= x*T(x)) for all x R. A Jordan *-centralizer of R is an additive mapping which is both left and right Jordan *-centralizer. The purpose of this paper is to prove the result concerning Jordan *-centralizer. The result which we refer state as follows: Let R be a 2-torsion free semiprime *-ring and let T: R R be an additive mapping such that 2T(x2) = T(x) x* + x* T(x) holds for all x R. In this case, T is a Jordan *-centralizer

Impulse Noise Removal From Highly Corrupted Astronomical Images using Modified Progressive Switching Median Filter Guided by Neural Networks
Hind
Restom Mohammed
In this paper, a novel and effective method for impulse noise removal in corrupted color images is discussed. The new method consists of three phases. The first phase is a noise detection phase where a modified self-organizing neural network is used to detect impulse noise pixels. The second is a noise filtering phase process is performed in recursive manner. Third phase is Histogram Equalizer the processed (output) image is obtained by mapping each pixel with level rk in the input image into a corresponding pixel with levels sk in the output image is presented. we propose a technique based on impulse noise detection by means of a self-organizing neural network and a class of the Modified Progressive Switching Median Filter(MPSM) that can remove impulse noise effectively while preserving details. Also, we add a histogram equalizer filter at the output of our proposed system in order to enhance the final output images. Experimental results demonstrate that the performance of the proposed technique is superior to that of the traditional median filter family for impulse noise removal in image applications.

In this paper a new method is proposed for the solution of two-point second order boundary-value problems( TPBVP ) ,that is, we interested in constructing polynomial solutions of two points second order boundary value problems for ordinary differential equation.
A semi-analytic technique using two-point osculatory interpolation with the fit equal numbers of derivatives at the end points of an interval [0,1] is compared with conventional methods via a series of examples and is shown to be that seems to converge faster and more accurately than the conventional methods and generally superior, particularly for problems involving nonlinear equations and/or boundary conditions

Abstract: Nowadays, with advancement of technology and science and expansion of computer usage in high-tech calculations, especially in the field of medicine, intelligence systems and in particular Neural Networks are becoming of significant importance in automatic diagnosis and prognoses of different diseases. This paper presents the diagnosis of thyroid diseases using Neural Networks. The genetic algorithm was used to find the optimum network structure with high classification accuracy. The experimental results presented for different proportions of training/testing groups show a high classification accuracy and convergence in rates. The overall accuracy is 100% for training and in range between 96% and 98% for testing. The neural networks are simulated using MATLAB. While thyroid disease datasets are taken from UCI machine learning dataset.

Let H and K be Hilbert spaces and let H⊕K be the cartesian product of them.Let B(H),B(K),B(H⊕K),B(K,H),B(H,K) be the Banach spaces of bounded(continuous) operators on H,K,H⊕K,and from K into H and from H into K respectively.In this paper we find the inverse of operator matrix B(H⊕K) where BєB(H) ,CєB(K,H), DєB(H,K), EєB(K) and A≥ , A where is the identity operator on H⊕K
