State-Space Approach to Structural Representation of Perturbed Pitch Period Sequences in Voice Signals
(Mosby-Elsevier, 2015-11)
Objectives: The aim of this study was to propose a state space-based approach to model perturbed pitch period sequences (PPSs), extracted from real sustained vowels, combining the principal features of disturbed real PPSs ...
A Dynamic-State Feedback Approach Employing a New State-Space Description for the Fast Wavelet Transform with Multiple Decomposition Levels
(2017-06-01)
This research paper proposes a wavelet-based dynamic-state feedback control strategy in the discrete time domain. In this proposal, the state feedback employs a state-space description for the fast wavelet transform, which ...
Conditions for Offset Elimination in State Space Receding Horizon Controllers: A Tutorial Analysis
(Elsevier, 2008-12)
An offset-free control is one that drives the controlled outputs to their desired targets at steady state. In the linear model predictive control (MPC) framework, the elimination of steady-state offset may seem a little ...
Optimal Identification of Potential-Radiation Hydrodynamics for Moored Floating Structures - A New General Approach in State Space
(Elsevier, 2004-12)
In this paper, a new state-space model of the potential-radiation hydrodynamics in moored ocean engineering floating structures and its parameter identification are presented. The raw data for this goal are the added mass ...
Modeling and joint estimation of glottal source and vocal tract filter by state-space methods
(Elsevier, 2017-08)
Accurate estimation of the glottal source from a voiced sound is a difficult blind separation problem in speech signal processing. In this work, state-space methods are investigated to enhance the joint estimation of the ...
Thermosolutal convective effects on dendritic array spacings in downward transient directional solidification of Al-Si alloys
(Elsevier Science SaLausanneSuíça, 2005)
Numerical study of the spherically symmetric Gross-Pitaevskii equation in two space dimensions
(2000-08-01)
The Gross-Pitaevskii equation for Bose-Einstein condensation (BEC) in two space dimensions under the action of a harmonic oscillator trap potential for bosonic atoms with attractive and repulsive interparticle interactions ...
Parameter Space Approach For State Space Induction Machine Modelling And Robust Control
(Sociedade Brasileira de Automatica, Vitoria, Brazil, 2000)
Cellular/dendritic transition during unsteady-state unidirectional solidification of Sn-Pb alloys
(Elsevier Science SaLausanneSuíça, 2003)
Ground state solution for differential equations with left and right fractional derivatives
(Wiley & Sons, 2015)
In this work, we study the existence of positive solutions for a class of fractional differential equation given by
D-t(infinity-infinity)alpha D(t)(alpha)u(t) + u(t) = f(t,u(t)),
u is an element of H-alpha (R), ...
