Title: Numerical Solution of Eighth Order Boundary Value Problems by Galerkin Method with Septic B-splines Authors: Ballem, Sreenivasulu; Kasi Viswanadham, K.N.S. Abstract: A finite element method involving Galerkin method with septic B-splines as basis functions has been solved the eighth order boundary value problems The basis functions are redefined into a new set of basis functions which vanish at the boundary where all types of boundary conditions are prescribed. The proposed method was applied to solve several examples of eighth order linear and nonlinear boundary value problems. To test the efficiency of the proposed method, obtained numerical results are compared with exact solutions available in the literature. Description: NITW

Title: Effect of Magnetic field on Entropy Generation due to Micropolar Fluid Flow in a Rectangular duct Authors: Srinivasacharya, D.; Hima Bindu, K. Abstract: The entropy generation due to heat transfer, fluid friction and magnetic field has been calculated for the steady, incompressible micropolar fluid flow in a rectangular duct with constant wall temperatures. An external uniform magnetic field is applied which is directed arbitrarily in a plane perpendicular to the flow direction. The governing partial differential equations of momentum, angular momentum and energy are solved numerically using Finite difference method. The obtained velocity, microrotation and temperature distributions are then used to evaluate the entropy generation and Bejan number. Finally the graphs are presented to show the influence of various physical parameters on entropy generation rate and Bejan number. Description: NITW

Title: Numerical Solution of Ninth Order Boundary Value Problems by Petrov-Galerkin Method with Quintic B-splines as Basis Functions and Septic B-splines as Weight Functions Authors: Kasi Viswanadham, K.N.S.; Reddy, S. M. Abstract: In this paper a finite element method involving Petrov-Galerkin method with quintic B-splines as basis functions and septic Bsplines as weight functions has been developed to solve a general ninth order boundary value problem with a particular case of boundary conditions. The basis functions are redefined into a new set of basis functions which vanish on the boundary where the Dirichlet, the Neumann and second order derivative type of boundary conditions are prescribed. The weight functions are also redefined into a new set of weight functions which in number match with the number of redefined basis functions. The proposed methodwasapplied to solve several examples of linear and nonlinear ninth order boundary value problems. The obtained numerical results were found to be in good agreement with the exact solutions available in the literature. Description: NITW

Title: Steganographic protocols based on rank metric codes Authors: Selvaraj, R.S.; Demamu, J. Abstract: Among the different applications where data hiding techniques can be used, one that has received huge attention in the recent years is steganography. With Matrix Embedding based on Hamming Codes which was first introduced by Crandall, coding theory has entered the field of steganography. In this paper, we investigate the application of q-ary codes with rank metric to steganography by using matrix embedding technique. We propose rank metric codes for steganographic security, as the nature of rank involves linear dependency or independency of symbols in the coordinates, which is more complex than merely comparing positions of bits. A method of constructing stego-codes using subcodes of linear codes is proposed. Some bounds, including the one for embedding efficiency, are also determined. Description: NITW
