Nonlinear electrodynamics as a symmetric hyperbolic system
(American Physical Society, 2015-10)
Nonlinear theories generalizing Maxwell's electromagnetism and arising from a Lagrangian formalism have dispersion relations in which propagation planes factor into null planes corresponding to two effective metrics which ...
Optimal Control of Nonlinear Chemical Reactors via an Initial-Value Hamiltonian Problem
(John Wiley & Sons Ltd, 2006-12)
The problem of designing strategies for optimal feedback control of nonlinear processes, specially for regulation and set-point changing, is attacked in this paper. A novel procedure based on the Hamiltonian equations ...
Use of piecewise linear models for optimal control of nonlinear systems
(Institute of Advanced Scientific Research, 2009-12)
The optimal feedback control of nonlinear process is attacked in this paper. The solution of this problem is numerically computed using a Continuous Piecewise Linear (CPWL) approximation of the Ordinary Differential Equations ...
Narrowband and ultra-wideband modulation instability in nonlinear metamaterial waveguides
(Optical Society of America, 2020-11)
Waveguides based on metamaterials may exhibit strongly frequency-dependent nonlinearities. In this work, we focus on the phenomenon of modulation instability in this type of waveguide, departing from a new modeling equation ...
Non-linear Dynamics Characterization from Wavelet Packet Transform for Automatic Recognition of Emotional Speech
(SpringerGrupo de Investigación en Telecomunicaciones Aplicadas (GITA)Basilea, Suiza, 2023)
Nonlinear methods of heart rate variability analysis in diabetes
(Drunpp-sarajevo, 2012-01-01)
Background: The autonomic dysfunction stands out among the complications associated to diabetes mellitus (DM) and may be evaluated through the heart rate variability (HRV), a noninvasive tool to investigate the autonomic ...
