Singularity formation for the two-dimensional harmonic map flow into S2
(Springer New York LLC, 2020)
© 2019, Springer-Verlag GmbH Germany, part of Springer Nature.We construct finite time blow-up solutions to the 2-dimensional harmonic map flow into the sphere S2, ut=Δu+|∇u|2uinΩ×(0,T)u=φon∂Ω×(0,T)u(·,0)=u0inΩ,where Ω is ...
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 ...
Effects of equation of state on hydrodynamic expansion, spectra, flow harmonics and two-pion interferometry
(World Scientific Publ Co Pte Ltd, 2018-07-01)
We perform an extensive study of the role played by the equation of state (EoS) in the hydrodynamic evolution of the matter produced in relativistic heavy ion collisions. By using the same initial conditions and freeze-out ...
Three-phase harmonic distortion state estimation algorithm based on evolutionary strategies
(ELSEVIER SCIENCE SA, 2010)
This paper presents a new methodology to estimate unbalanced harmonic distortions in a power system, based on measurements of a limited number of given sites. The algorithm utilizes evolutionary strategies (ES), a development ...
Modeling approach based on experimental results for prediction of measurement errors in energy meters

Time-varying harmonic analysis in electric power systems with wind farms, through the possibility theory
(Universidad Nacional de Colombia (Sede Medellín). Facultad de Minas., 2015-07-01)
This paper focuses on the analysis of the connection of wind farms to the electric power system and their impact on the harmonic load-flow. A possibilistic harmonic load-flow methodology, previously developed by the authors, ...
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 ...
