An analysis of the reaction diffusion in a carrier-mediated transport process through a membrane is presented. A simple approximate analytical expression of concentration profiles is derived in terms of all dimensionless parameters. Furthermore, in this work we employ the homotopy perturbation method to solve the nonlinear reaction–diffusion equations.(More)
– This paper presents a comparison of segmentation methods. The segmentation methods are time domain features and frequency domain features. The time domain features are short time energy, short time zero crossing rate. The frequency domain features are spectral centroid and spectral flux. After features are extracted, a simple thresholding method is used(More)
