A Numerical method for the Viscoelastic Melt Spinning Model with Radial resolutions of Temperature and Stress Fields
(American Chemical Society, 2002-06)
A numerical method to compute the viscoelastic melt-spinning model with radial resolutions of temperature and stress fields is formulated and applied to the low speed range. The starting framework is the reduction of the ...
Rodlike localized structure in isotropic pattern-forming systems
(American Physical Society, 2015)
Stationary two-dimensional localized structures have been observed in a wide variety of dissipative systems. The existence, stability properties, dynamical evolution, and bifurcation diagram of an azimuthal symmetry breaking, ...
Coalescence, deformation and Bäcklund symmetries of Painlevé IV and II equations
(2020-11-01)
We extend Painlevé IV model by adding quadratic terms to its Hamiltonian obtaining two classes of models (coalescence and deformation) that interpolate between Painlevé IV and II equations for special limits of the underlying ...
Space-time least-squares finite elements for parabolic equations
(2021)
We present a space-time least-squares finite element method for the heat equation. It is based on residual minimization in L-2 norms in space-time of an equivalent first order system. This implies that (i) the resulting ...
A structural equation modeling of executive functions, IQ and mathematical skills in primary students: Differential effects on number production, mental calculus and arithmetical problems
(Psychology Press, 2016-07)
Though the relationship between executive functions (EFs) andmathematical skills has been well documented, little is knownabout how both EFs and IQ differentially support diverse mathdomains in primary students. Inconsistency ...
