Two-layer Couette flow of a third grade fluid is studied. Optimal Homotopy Asymptotic Method is used to find solutions of coupled nonlinear differential equations governing the motion of two immiscible layers of fluids with equal thickness. The solution expressions are used to model the flow and to illustrate the effect of variable material constants on the fluids' motion.
The role of inadequate retinal oxygenation in the development of retinal diseases is an important problem for investigation. In our study, quantitative measurement of oxygen tension in retinal vasculatures is made with the noninvasive technique of phosphorescence lifetime imaging. A frequency domain approach is used to estimate the fluorescence or phosphorescence lifetime by regression analysis. Measurements...
In peer-to-peer (P2P) and overlay network environments, digital multimedia is allowed to be freely copied, shared and disseminated in a decentralized manner. Such environments do not guarantee authentication or preservation of the data. Furthermore, if the multimedia data, particularly video, images, or audio, has been polluted during this sharing process, there are no decentralized mechanisms that...
