Validation of a Galerkin technique on a boundary integral equation for creeping flow around a torus
(Sociedade Brasileira de Matemática Aplicada e Computacional, 2013-06-21)
A validation of the numerical solution for the steady and axisymmetric creeping flow around a three-dimensional torus is presented. This solution is obtained by means of the Boundary Element Method. Both, a Galerkin weighting ...
Detection of limit cycle bifurcations using harmonic balance methods
(World Scientific, 2004-12)
In this paper, bifurcations of limit cycles close to certain singularities of the vector fields are explored using an algorithm based on the harmonic balance method, the theory of nonlinear feedback systems and the monodromy ...
Nonlinear Interaction Between the Tide and the Storm Surge with the Current due to the River Flow in the Río de la Plata
(Springer, 2020-11)
The Río de la Plata estuary (RdP) is characterized by the large flow of its tributary rivers (Q), with an average of 22,000 m3 s− 1 and an interannual variability range from 8000 to 90,000 m3 s− 1. In this work, the ...
On semi-analytical procedure for detecting limit cycle bifurcations
(World Scientific, 2004-12)
This paper reports some computation of periodic solutions arising from Hopf bifurcations in order to build up a more accurate procedure for semi-analytical approximations to detect limit cycle bifurcations. The approximation ...
Novel modified phase-shift modulation strategy for isolated AC-DC power converters
(Institution of Engineering and Technology, 2020-04)
Different power converter topologies are used to perform the energy exchange between an AC grid and a DC source belonging to a hybrid electric micro-grid. A single-phase single-stage isolated AC-DC power converter is one ...
Measurement of flow harmonics with multi-particle cumulants in Pb+Pb collisions at √sNN = 2.76 TeV with the ATLAS detector
(Springer, 2014-12)
ATLAS measurements of the azimuthal anisotropy in lead?lead collisions at s NN = 2.76 TeV areshown using a dataset of approximately 7 μb −1 collected at the LHC in 2010. The measurements areperformed for charged particles ...
Isolated bidirectional DC-to-three-phase AC converter for integration of renewable energy sources to electric grid
(Institution of Engineering and Technology, 2019-07)
In this study, a new isolated bidirectional DC-to-three-phase AC converter for integration of renewable energy sources to the electric grid is presented. The main features of this topology are galvanic isolation, capability ...
Impact of nonlinear lighting loads on the neutral conductor current of low voltage residential grids
(MDPI AG, 2020-09)
In the last decade, mainly due to political incentives towards energy efficiency, the share of lamps with power electronic interfaces, like Compact Fluorescent Lamps (CFL) and Light Emitting Diode (LED) lamps, has significantly ...
IFRS is globalization in accounting termsLas NIIF son la globalización en términos contables
Las Normas Internacionales de Información Financiera (NIIF) o (IFRS por su sigla en inglés) surgen a partir de la globalización económica esta crea la necesidad de aplicar normas y, por ende, de hacer parte del proceso de ...
