in this paper, the modified simplest equation method is successfully implemented to find travelling wave solutions of the generalized forms $b(n,1)$ and $b(-n,1)$ of burgers equation.this method is direct, effective and easy to calculate, and it is a powerful mathematical tool for obtaining exact travelling wave solutions of the generalized forms $b(n,1)$ and $b(-n,1)$ of burgers equation and c...

High-quality DNA extraction plays an important role to make sharp bands in the gel electrophoresis and also produces clean chromatograms. Usually, DNA extract is delivered using the modified CTAB method but this method cannot obtain high-quality DNA for molecular analysis from old dried leaves of Bellevalia due to having different chemical compounds which inhibit to obtain a clear DNA extractio...

In this paper a novel edge detection method has been proposed which outperform Otsu method [1]. The proposed detection algorithm has been devised using the concept of genetic algorithm in spatial domain. The key of edge detection is the choice of threshold; which determines the results of edge detection. GA has been used to determine an optimal threshold over the image. Results are compared wit...

In this paper we further improve the modified extended tanh-function method to obtain new exact solutions for nonlinear partial differential equations. Numerical applications of the proposed method are verified by solving the improved Boussinesq equation and the system of variant Boussinesq equations. The new exact solutions for these equations include Jacobi elliptic doubly periodic type, Weie...

A new approach is adopted in this paper based on Turk and Pentland’s eigenface method. It was found that the probability density function of the distance between the projection vector of the input face image and the average projection vector of the subject in the face database, follows Rayleigh distribution. In order to decrease the false acceptance rate and increase the recognition rate, the i...

In assaying for sulfatases it is possible to use several methods which have been devised for the determination of inorganic sulfate. As a test for chondrosulfatase, the micro benzidine method developed by Dodgson and Spencer (1) is usually employed. This method appears to be the most suitable because of its good sensitivity and absence of substrate interference, but its technique is complicated...

In this paper, we apply modified decomposition method (MDM) to solve systems of partial differential equations. Several examples are given to verify the reliability and efficiency of the method. Numerical results clearly reveal the complete reliability of the proposed algorithm.

The Modified C.S.R. Test It was decided to deve lo~ a filterabilitv test incorporating the best features bf the two existing tests, and to compare results obtained by the new method with those obtained by the bomb method and the C.S.R. test at 20" C. To overcome sampling problems it was decided that results should be grouped on a monthly basis. Details of the modified C.S.R. method appear in th...
