We present and compare various types of discretizations which have been proposed to approximate the total variation (mostly, a gray-level image in two dimensions). discuss properties finite differences elements based approach their merits, particular terms error estimates quality reconstruction.
mathematical modeling of heat transfer and sterilizing value evaluation during caviar pasteurization
in this study, a numerical model was developed to investigate the two-dimensional heat transfer in a homogenous finite cylinder to predict the local temperature and sterilizing value during caviar pasteurization. a fixed grid finite difference method was used in the solution of heat transfer equations according to crank-nicolson’s scheme. the model was validated by comparison of the experimenta...
in chemical engineering, several processes are represented by singular boundary value problems. in general, classical numerical methods fail to produce good approximations for the singular boundary value problems. in this paper, chebyshev finite difference (chfd) method and dtm-pad´e method, which is a combination of differential transform method (dtm) and pad´e approximant, are applied for sol...
