In this paper, we use the optimal homotopy asymptotic method (OHAM) for the solution of Non-linear two dimensional incompressible laminar boundary layer flow of fluid in the presence of transverse magnetic field. The obtained results for the stream function and velocity profile were comparable in terms of accuracy with that obtained by A. Abdullah (2009)(More)
This paper is a review of image segmentation is to partition an image into non-overlapping regions based on intensity or textural information. The active contour is one of the most successful variational models in image segmentation. It consists of evolving a contour in images toward the boundaries of objects. After reviewing, we have proposed an approach(More)
In this paper we have developed the mechanism to remove unwanted low or high amplitudes from the given input speech. The input speech is divided into many small segments of very short interval. These segments are checked against the given amplitude. The unwanted amplitude segments are filtered out while the desired amplitude segments are selected. All(More)
The purpose of the present paper is to study an unsteady laminar flow of an incompressible conducting viscous dusty fluid between two infinitely non-conducting parallel plates, where above plate is bounded by porous medium. The flow is influenced by pulsatile pressure gradient, uniform magnetic field which is applied perpendicular to the plates and due to(More)
