In this paper, the homotopy-perturbation method (HPM) is employed to obtain approximate analytical solution to the linear and nonlinear systems of partial di®erential equations (PDEs). HPM yields solutions in convergent series forms with easily computable terms. Generally, the closed form of the exact solution or its expansion is obtained without

In this work, an analytical expression for the solution of the the reaction-diffusion Brusselator model is derived by the homotopyperturbation method. The advantage of this work is twofold. Firstly, the homotopy-perturbation method reduces the computational work. Secondly, in comparison with existing techniques, the homotopy-perturbation method is

This research discusses the employers’ perception and expectation of the undergraduate competency and personality. Research methodology is based on questionnaires survey and in depth interview on 100 employers. It focuses on employers that consist private and public sectors. The main findings show that factors such as mediocre or low academic ach

Previous research on the internationalization of small and medium enterprises (SMEs) explored the relationship between adoption of global orientation and competitive advantage, management attitude, and international knowledge and experience. However, there was a difference in opinion between those arguing that there is a positive relationship betwe

a common problem shared by many institution of higher learning around the world today is the wide discrepancy in the enrollment of males and females.although the gender gap inpublic universities has been widely highlited in malaysia.it is believed this problem may be inextricably linked to gender differences in achievement at the school level.it ha

...This chapter aims to report on a study concerning migrant workers and their effects on the host country. The objective of the study is to investigate the effect of migrants on (i)the relative price and the wage rate, and (ii)the welfare of the native inhabitants in the host country. The methodology for the study involves a two-factors and two-se

In this paper, the homotopy-perturbation method (HPM) is applied to obtain approximate analytical solutions for the Cauchy reaction-diffusion problems. HPM yields solutions in convergent series forms with easily computable terms. The HPM is tested for several examples. Comparisons of the results obtained by the HPM with that obtained by the Adomian

In this paper, a new reliable algorithm based on an adaptation of the standard homotopy-perturbation method (HPM) is presented. The HPM is treated, as an algorithm in a sequence of intervals (ie time step) for finding accurate approximate solutions to the famous Lorenz system. Numerical comparisons between the multistage homotopy-perturbation metho

Many researchers and practitioners from the industry would agree on the importance of corporate entrepreneurship as an effective means for rejuvenating companies and improving their financial performance. In the era of intense global competition, Small and Medium Enterprises (SMEs) realize that a greater focus is required in entrepreneurial behavio
