Magnetic field evolution in neutron stars: one-dimensional multi-fluid model
(EDP SCIENCES S A, 2008-09)
Aims. This paper is the first in a series that aims to understand the long-term evolution of neutron star magnetic fields.
Methods. We model the stellar matter as an electrically neutral and lightly-ionized plasma composed ...
Pulsatile flow between two coaxial porous cylinders with slip on inner cylinder.
(2011-10-13)
A fully developed, axisymmetric, pulsatile motion of an incompressible Newtonian fluid,under the action of an oscillatory pressure gradient, has been considered in this work. The fl ow is assumed to take place in the ...
Solução numérica da equação de Poisson em malhas estruturadas bidimensionais e tridimensionais
(Universidade Tecnológica Federal do ParanáCuritibaBrasilLicenciatura em MatemáticaUTFPR, 2021-08-23)
In this work, we numerically solve second-order elliptic partial differential equations such as the Laplace and Poisson equations, using the finite difference method in two-dimensional and threedimensional structured meshes. ...

Estudo de ondas viajantes não lineares de perfil saturado
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Física - PPGF, 2013-04-29)
In this paper, we study a class of nonlinear waves in one dimension using the assumption of traveling waves. First we found the solutions to the partial differential equation (PDE) containing a term of nonlinear inhomogeneity, ...
C programs for solving the time-dependent Gross-Pitaevskii equation in a fully anisotropic trap
(Elsevier B.V., 2012-09-01)
We present C programming language versions of earlier published Fortran programs (Muruganandam and Adhikari (2009)[1]) for calculating both stationary and non-stationary solutions of the time-dependent Gross-Pitaevskii ...

Two additions to Lucas's 'inflation and welfare'
(Escola de Pós-Graduação em Economia da FGV, 2004-04-01)
This work adds to Lucas (2000) by providing analytical solutions to two problems that are solved only numerically by the author. The first part uses a theorem in control theory (Arrow' s sufficiency theorem) to provide ...
