A hybrid symbolic-numerical approach to the center-focus problem
(2017-09-01)
We propose a new hybrid symbolic-numerical approach to the center-focus problem. The method allowed us to obtain center conditions for a three-dimensional system of differential equations, which was previously not possible ...
Rural electrification and respiratory health: an empirical approach in Peru
(American Thoracic Society, 2015)
In Peru, most rural homes do not have access to electricity, water, or sewage networks and they use traditional biomass stoves, which can cause respiratory diseases. The objective of this study was to determine whether ...
Rock pillar design using amasonry equivalent numerical model
(MDPI, 2021)
In underground mining, the design of rock pillars is of crucial importance as these are
structures that allow safe mining by maintaining the stability of the surrounding excavations. Pillar
design is often a complex task, ...
Three-dimensional transient complex free surface flows: Numerical simulation of XPP fluid
(2013-05-01)
In this paper we present a finite difference MAC-type approach for solving three-dimensional viscoelastic incompressible free surface flows governed by the eXtended Pom-Pom (XPP) model, considering a wide range of parameters. ...
