Aspectos evolutivos de la guitarra flamenca en relación con el cante
(Libros con duende, 2015)
La música flamenca, como música de tradición oral, está involucrada en un continuo proceso de evolución y cambio influenciado por el marco cultural donde se desarrolla. En este trabajo apuntamos varios casos en los que ha ...

Enhancing nonlinear solvers for the Navier–Stokes equations with continuous (noisy) data assimilation
(Elsevier, 2024-05)
We consider nonlinear solvers for the incompressible, steady (or at a fixed time step for unsteady) Navier–Stokes equations in the setting where partial measurement data of the solution is available. The measurement data ...

Delay effects on the limit cycling behavior in an H-bridge resonant inverter with zero current switching control strategy
(2018)
In this paper, bifurcations of limit cycles in a H-bridge LC resonant inverter under a zero current switching control strategy with delay in the switching action are analyzed. Mathematical analysis and numerical simulations ...

Monotone crossing number of complete graphs
(2013)
In 1958, Hill conjectured that the minimum number of crossings in a drawing of Kn is exactly Z(n) = 1/4 n-1/2/2 n−2/2 n−3/2. Generalizing the result by Ábrego et al. for 2-page book drawings, we prove this conjecture for ...

On the existence and uniqueness of limit cycles in Liénard differential equations allowing discontinuities
(IOP Science, 2008)
In this paper we study the non-existence and the uniqueness of limit cycles for the Liénard differential equation of the form x'' − f(x)x' + g(x) = 0 where the functions f and g satisfy xf(x) > 0 and xg(x) > 0 for x ≠ 0 ...

Simulating distributed algorithms for lattice agents
(2013)
We present a practical Java tool for simulating synchronized distributed algorithms on sets of 2-and 3-dimensional square/cubic lattice-based agents. This AgentSystem assumes that each agent is capable to change position ...

On the enumeration of permutominoes
(2013)
Although the exact counting and enumeration of polyominoes remain challenging open problems, several positive results were achieved for special classes of polyominoes. We give an algorithm for direct enumeration of ...

A general vertical decomposition of Euler equations: Multilayer-moment models
(Elsevier, 2023-01)
In this work, we present a general framework for vertical discretizations of Euler equations. It generalizes the usual moment and multilayer models and allows to obtain a family of multilayer-moment models. It considers a ...

Extensión de juegos definidos en sistemas de conjuntos
(1998)
"Este trabajo de investigación, fundamentalmente, propone un nuevo modelo para la generalización del iniciado por Myerson (1977). Con este objetivo se analizan estructuras estables para la unión de coaliciones con intersección ...
