Probing numerical Laplace inversion methods for two and three-site molecular exchange between interconnected pore structures
(Academic Press Inc Elsevier Science, 2018-01)
Two-dimension (2D) Nuclear Magnetic Resonance relaxometry experiments are a powerful tool extensively used to probe the interaction among different pore structures, mostly in inorganic systems. The analysis of the collected ...
Wavelet-Petrov-Galerkin Method for the Numerical Solution of the KdV Equation
(Hikari, 2012)
The development of numerical techniques for obtaining approximate solutions of partial differential equations has very much increased in the last decades. Among these techniques are the finite element methods and finite ...
Spectral discretizations of the Darcy's equations with non standard boundary conditions
(USFQ PRESS, departamento editorial de la Universidad San Francisco de Quito USFQ, 2018)
A 3D numerical model of an ONAN distribution transformer
(Pergamon-Elsevier Science Ltd, 2019-02-05)
The aim of this work is to validate a numerical model used to simulate the natural convection in a distribution transformer. The transformer of interest is of the oil natural air natural (ONAN) type and the model seeks to ...
Error analysis of generalized-alpha Lie group time integration methods for constrained mechanical systems
(Springer, 2015-01)
Generalized-α methods are very popular in structural dynamics. They are methods of Newmark type and combine favourable stability properties with second order convergence for unconstrained second order systems in linear ...
Hydrostatic equilibrium preservation in MHD numerical simulation with stratified atmospheres: Explicit Godunov-type schemes with MUSCL reconstruction
(EDP Sciences, 2019-11)
Many astrophysical processes involving plasma flows are produced in the context of a gravitationally stratified atmosphere in hydrostatic equilibrium, in which strong gradients can exist with gas properties that vary in ...
Control of Porosity in Freeze Casting
(J O M Institute, 2020-01-01)
Many biologic structural materials have porous microstructures with a distribution and orientation of pores that are challenging to achieve using traditional methods of processing. In this investigation, numerical and ...
