Performance Analysis of Fusion Classifier of Face Recognition System based on ANN and GA
Abstract: Though a lot of significant work has been done for recognizing and improving the performance in facial pattern, most techniques have been developed based on a single classifier. But most often, the performance of the classifier is not satisfactory in some case. It has been proposed that the performance of face recognition will beimproved by fusing two or more classifiers. We can combine the information/data in different level i.e., feature …

Non-Newtonian Power-law Fluid Flows for Shear Thinning Viscosity in a T junction Channel
Abstract: In this paper, non-Newtonian fluid flow behaviors are analyzed in a two-dimensional T junction channel using Lattice-Boltzmann Method (LBM). The LBM has been built up on the D2Q9 model, and the single-relaxation-time (SRT) method called the Lattice-BGK (Bhatnagar-Gross-Krook) model. The flow patterns are analogous to blood flows in branched arteries for T junction flows. Firstly, the code validation has been occurred for the Newto-nian fluid flows by comparing the accessible …
