Equações diferenciais ordinárias não suaves autônomas e não autônomas
(Universidade Estadual Paulista (Unesp), 2016-05-20)
Nesta tese estudamos sistemas dinâmicos não suaves autônomos e não autônomos. Consideramos inicialmente sistemas quadráticos positivamente limitados autônomos planares e damos condições sobre os campos para que o sistema ...
Non-linear pseudo-differential evolution equation in fractional time.
(Universidad de Concepción.Facultad de Ciencias Físicas y Matemáticas, 2023)
Fractional calculus is the part of mathematical analysis that studies derivatives and integrals of any arbitrary order, real or complex. We usually refer to it when we want to describe evolution problems with memory. The ...
Parametric uncertainty and disturbance attenuation in the suboptimal control of a non-linear electrochemical process
(John Wiley & Sons Ltd, 2007-12)
The optimal control of the hydrogen evolution reactions is attempted for the regulation and change of setpoint problems, taking into account that model parameters are uncertain and I/O signals are corrupted by noise. ...
Variational iteration algorithm-II for solving linear and non-linear ODEs
(International Journal of the Physical Sciences, 2012)
A piezoelectric beam model with geometric, material and damping nonlinearities for energy harvesting
(IOP Publishing, 2020-09-10)
To predict electrical generation in piezoelectric small-scale beam energy harvesting devices, it is important to have a complete mathematical model that captures the different associated phenomena. In the literature, some ...
