Parametric perturbation in a model that describes the neuronal membrane potential
(2019-02-01)
The Rulkov mapping is a phenomenological model that simulates the changes in the neuronal membrane potential. In this work, we introduce a parametric perturbation in the Rulkov map, that can be related to an unexpected ...
Tree-structured smooth transition models
(Escola de Pós-Graduação em Economia da FGV, 2005-11-03)
The goal of this paper is to introduce a class of tree-structured models that combines aspects of regression trees and smooth transition regression models. The model is called the Smooth Transition Regression Tree (STR-Tree). ...

Parametric and semi-parametric cure rate models with spatial frailties for interval-censored data
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Estatística - PPGEsCâmpus São Carlos, 2016-05-31)
In this thesis, we extend some flexible cure rate models, such as the geometric, negative
binomial and power series cure rate models, to allow for spatial correlations by including spatial
frailties for the interval ...
The role of no-arbitrage on forecasting: lessons from a parametric term structure model
(Escola de Pós-Graduação em Economia da FGV, 2007-10-01)
Parametric term structure models have been successfully applied to innumerous problems in fixed income markets, including pricing, hedging, managing risk, as well as studying monetary policy implications. On their turn, ...
Parametric model for the analysis of concrete expansion due to alkali-aggregate reaction
(PROFESSIONAL ENGINEERING PUBLISHING LTD, 2008)
The alkali-aggregate reaction (AAR) is a chemical reaction that provokes a heterogeneous expansion of concrete and reduces important properties such as Young's modulus, leading to a reduction in the structure's useful life. ...
Measurement of the velocity eld in parametrically excited solitary waves
(Cambridge University Press, 2014)
Parametrically excited solitary waves emerge as localized structures in high-aspectratio
free surfaces subject to vertical vibrations. Herein, we provide the first experimental
characterization of the hydrodynamics of ...
