An efficient explicit group method for time fractional Burgers equation
Frontiers in PhysicsFractional Burgers-type equations are essential mathematical models for describing the cumulative effect of wall friction through the boundary layer, along with the unidirectional propagation of weakly nonlinear acoustic waves. It is a major challenge to

Image Restoration using a Nonlinear Second-order Parabolic PDE-based Scheme
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2017 A novel anisotropic diffusion-based image denoising and restoration approach is proposed in this paper. A variational model for image restoration is introduced first, then the corresponding Euler-Lagrange equation being determined.

Soliton propagation in lossy optical fibers
Semina: Ciências Exatas e Tecnológicas, 2019 In this work we study the propagation of solitons in lossy optical fibers. The main objective of this work is to study the loss of energy of the soliton wave during propagation and then to evaluate the impact of this loss on the transmission of the ...

Um modelo numérico baseado no sistema de coordenadas curvilíneas para o método MAC simplificado
Semina: Ciências Exatas e Tecnológicas, 2018 Neste trabalho desenvolvemos uma metodologia numérica para estudar alguns fluxos de fluidos incompressíveis sem superfícies livres, usando o sistema de coordenadas curvilíneas e com a geometria do contorno construída através de splines parametrizadas ...
