Reactivity indices and response functions in density functional theory
(Elsevier, 1998)
The hardness and softness quantities defined in density functional theory are discussed. A new scheme to calculate the hardness and softness hierarchies without resorting to the finite difference approximation is outlined. ...
Linear functional regression: The case of fixed design and functional response
(Universidad de San Andrés. Departamento de Matemáticas y Ciencias, 2011)
Robust tests in generalized linear models with missing responses
(Elsevier Science Bv, 2013-09)
In many situations, data follow a generalized linear model in which the mean of the responses is modelled, through a link function, linearly on the covariates. Robust estimators for the regression parameter in order to ...
Sufficients conditions for analysis of extrema in the step-response of the linear control systems
(Institute of Electrical and Electronics Engineers (IEEE), 2011-12-01)
This note deals whith the problem of extrema which may occur in the step-response of a stable linear system with real zeros and poles. Some simple sufficients conditions and necessary conditions are presented for analyses ...
Algorithms for network piecewise-linear programs: A comparative study
(1997-02-16)
Piecewise-Linear Programming (PLP) is an important area of Mathematical Programming and concerns the minimisation of a convex separable piecewise-linear objective function, subject to linear constraints. In this paper a ...
Sufficients conditions for analysis of extrema in the step-response of the linear control systems
(Institute of Electrical and Electronics Engineers (IEEE), 2014)
Robust inference in partially linear models with missing responses
(Elsevier Science, 2014-11)
We consider robust testing on the regression parameter of a partially linear regression model, where missing responses are allowed. We derive the asymptotic behavior of the proposed test statistic under the null and ...
Modelos de predição para sobrevivência de plantas de Eucalyptus grandis
(Editora da Universidade Federal de Lavras, 2009)
Objetivou-se com este trabalho comparar modelos de predição de plantas sobreviventes de Eucalyptus grandis. Utilizaram-se os seguintes modelos: modelo linear misto com os dados transformados, utilizando-se as transformações ...
Fuzzy pole placement based on piecewise Lyapunov functions
(JOHN WILEY & SONS LTD, 2010)
This paper presents a controller design method for fuzzy dynamic systems based on piecewise Lyapunov functions with constraints on the closed-loop pole location. The main idea is to use switched controllers to locate the ...
