Transmission lines model with different basic structures applied to transient electromagnetic simulations
Models based on lumped elements are simple ones to represent systems composed by distributed parameters when models with lumped elements use a lot of these elements. However, such mentioned models usually present numerical ...
Determination of the numerical parameters of a continuous damage model for the structural analysis of clay brick masonry
(Universidade Federal de São Carlos (UFSCar), Dept Engenharia Materials, 2014)
Thermal stress analysis of a directionally solidified Al-1 wt%Ni alloy casting

Integration Methods Used in Numerical Simulations of Electromagnetic Transients
(Institute of Electrical and Electronics Engineers (IEEE), 2011-12-01)
This paper made an analysis of some numerical integration methods that can be used in electromagnetic transient simulations. Among the existing methods, we analyzed the trapezoidal integration method (or Heun formula), ...
Perturbations of asymptotically stable differential systems.
We consider systems of differential equations of the form (1) x’ = f(t,x), for t ∊ [a,∞), x in some domain D ⊂ IRn and f ∈ c1 ([a,∞) × D) (a a fixed real number). We assume that the solution x(t,to,xo) of (1) defined for ...
Simple estimation of linear 1+1 D long wave run-up
(Oxford University Press, 2017-05)
An analytical solution is derived concerning the linear run-up for any given initial wave generated over a sloping bathymetry. Due to the simplicity of the linear formulation, complex transformations are unnecessary, hence ...
NUMERICAL QUENCHING FOR A SEMILINEAR PARABOLIC EQUATION WITH A POTENTIAL AND GENERAL NONLINEARITIES
(Universidad Católica del Norte, Departamento de Matemáticas, 2008)
Numerical analysis of si and gaas solar cells exposed to space radiation
(Institute of Electrical and Electronics Engineers, 2013-02)
In this paper, we present a study about Si and GaAs space solar cells by means of numerical simulations. We have investigated the variations of the short-circuit current, open circuit voltage and maximum power point, before ...
Experimental and numerical analysis to collapse of a framed structure subjected to seismic loading
The nonlinear numerical analysis to collapse of civil structures presents several difficulties, even for mechanically well-characterized materials, such as steel. In the case of steel, where the nonlinear constitutive ...
