Time-fractional telegraph equation of distributed order in higher dimensions with Hilfer fractional derivatives

Autor: Nelson Vieira, M. Manuela Rodrigues, Milton Ferreira

Publikováno v: Electronic Research Archive, Vol 30, Iss 10, Pp 3595-3631 (2022)

In this paper, we consider the time-fractional telegraph equation of distributed order in higher spatial dimensions, where the time derivative is in the sense of Hilfer, thus interpolating between the Riemann-Liouville and the Caputo fractional deriv

Fractional Gradient Methods via ψ-Hilfer Derivative

Autor: Nelson Vieira, M. Manuela Rodrigues, Milton Ferreira

Publikováno v: Fractal and Fractional, Vol 7, Iss 3, p 275 (2023)

Motivated by the increase in practical applications of fractional calculus, we study the classical gradient method under the perspective of the ψ-Hilfer derivative. This allows us to cover several definitions of fractional derivatives that are found

An explicit delamination propagation algorithm to simulate delamination growth under quasi-static and fatigue loading without re-meshing using virtual crack closure technique and progressive nodal release

Autor: Nelson Vieira De Carvalho, Madhavadas Ramnath, Gerald E. Mabson, Ronald Krueger

Publikováno v: Journal of Composite Materials. 56:2063-2081

A modeling approach is proposed to simulate delamination propagation in composite laminates under both quasi-static and fatigue loading regimes. Delamination growth is simulated using the Virtual Crack Closure Technique combined with a progressive no

Bicomplex Neural Networks with Hypergeometric Activation Functions

Autor: Nelson Vieira

Publikováno v: Advances in Applied Clifford Algebras. 33

Bicomplex convolutional neural networks (BCCNN) are a natural extension of the quaternion convolutional neural networks for the bicomplex case. As it happens with the quaternionic case, BCCNN has the capability of learning and modelling external depe

O OBSERVATÓRIO DA EDUCAÇÃO E AS QUESTÕES DE GÊNERO E VIOLÊNCIA ESCOLAR: confronto entre meninas

Autor: Nelson Vieira Torres, Elson Luis de Araujo

Publikováno v: Interfaces da Educação, Vol 6, Iss 16, Pp 90-102 (2015)

A violência na atualidade tem preocupado a sociedade na medida em que se torna mais corriqueira e presente nos diversos espaços sociais. Os estudantes estão ao mesmo tempo sendo agressores e vítimas, envolvidos num universo de coação, provocaç

Time-fractional diffusion equation with psi-Hilfer derivative

Autor: Milton Ferreira, Nelson Vieira, M. Manuela Rodrigues

In this work, we consider the multidimensional time-fractional diffusion equation with the $\psi$-Hilfer derivative. This fractional derivative enables the interpolation between Riemann-Liouville and Caputo fractional derivatives and its kernel depen

The article addresses the influence of the dominant hegemony on Brazilian public education, fundamentally on vocational and technological education (EPT), through the use of three mechanisms of capitalism to inhibit any possibility of public educatio
