Abstract: We consider a non - linear variant of the transport- diffusion osmosis model for solving a variety of imaging problems such as shadow/soft-light removal and compact data representation ...
and computationally efficient results are obtained in comparison to standard linear and anisotropic models, and state-of-the art approaches. We consider a non - linear variant of the transport-diusion osmosis model ...
In this paper, we present a wavelet-based approach to solve the non - linear perturbation equation encountered in optical tomography. A particularly suitable data gathering geometry is used to gather ...
and shifted uniform sampling. The irregular sampling scheme is the general scenario, while computationally efficient solutions are available in the spectral domain for non -uniform and shifted uniform sampling ...
In this paper, we have applied an accurate and efficient wavelet scheme (due to Legendre polynomial) to find the numerical solutions for a set of coupled reaction– diffusion equations. This technique ...
of accuracy, the linearized convection– diffusion –reaction finite‐difference equation is solved line‐by‐line using the nodally exact one‐dimensional scheme . The matrix size is reduced and, at the same time ...

of non -uniform mesh known as exponentially graded mesh to resolve the layer behaviour of the solution. Using an exponentially graded mesh with Haar wavelet scheme is a novelty. As the Haar functions ...
of terms in the PDE model similar to the equation learning approach of Brunton and colleagues [4, 7]. Our approach is computationally efficient since we require a relatively small number of bootstrap samples ...
