In this paper, the homotopy-perturbation method (HPM)proposed by J.-H. He is adopted for solving linear and nonlinear systems of partial differential equations (PDEs). In this method, a homotopy parameter p, which takes the values from 0 to 1, is introduced. When p = 0, the system of equations usually reduces to a sufficiently simplified form, whic

Objective: To find out the effect of strength training of dorsiflexors of ankle on the balance in elderly. Methods: Healthy elderly were selected and divided into two groups. One group got stretching, mobilization and strength training of ankle dorsiflexors while no exercises were given to the other group. Balance of the two groups were compared by

In this study, we applied a new algorithm based on Homotopy Perturbation Method (HPM) to evaluate the temperature distribution of a straight rectangular fin with temperature dependent surface heat flux for all possible types of heat transfer. The local heat transfer coefficient is considered to vary with a power-law function of temperature. The tim

Firstly, this article briefly discusses the concept of maslahah in Islam. Relevant verses in the Qur’an and hadith of the Prophet Muhammad s.a.w are referred to show that the principle of maslahah has strong supportive authorities in Shariah. Secondly, the application of the principle of maslahah in custody dispute is deliberated. The application

In most western countries there is now a consensus that shared parenting is the best alternative for children when their parents separate or divorce. Maintaining elationships with both parents after their divorce, by way of a shared parenting arrangement is said to be the best for the child compared to merely providing contact for the child and the

In the struggle to prove the perseverance of ؤivilizations, some nations tend to cancel the identities of others. In this regard, Muslims must have their own position derived from the age long experience of the Islamic civilization in order to strike the same chord between the various nations and peoples of the Islamic belief. This experience is f

Rotating machinery is a common class of machinery in industry. The root cause of faults in rotating machinery is often faulty rolling element bearings. These rolling element bearings wear out easily due to the metal-metal contacts and create faults in the outer race, inner race, or balls. This study compares several techniques used for monitoring b

The empirical propagation path loss models have important influence in mobile communication systems design. They become important tools in both research and industrial communities owing to their speed of implementation and their limited dependence on detailed knowledge of the terrain. The mobile services are increasing rapidly and hence the mobile

The design of a propagation path loss model requires knowledge of environment characteristics. Quite a number of propagation path loss models for mobile radio communication system were published in the literature. However, choosing the most suitable model for a given geographical and morphographical area is not a simple task because descriptions of

The electrocardiogram is a common diagnostic tool used to monitor heart activity and can provide information about the cardiovascular problems. An automatic detection of the ECG traces can be valuable aid in the diagnosis process. The wavelet transform has proven to be an important tool in the analysis of biomedical signals, and the ECG in particul
