HTS: A new shape descriptor based on Hough Transform
(2013-09-09)
In this paper we propose a novel method for shape analysis called HTS (Hough Transform Statistics), which uses statistics from Hough Transform space in order to characterize the shape of objects in digital images. Experimental ...
Chain recurrence and average shadowing in dynamics
(2021-01-01)
We investigate several notions related to pseudotrajectories, including chain recurrence and shadowing properties, for a special class of diffeomorphisms on euclidean spheres, known as spherical linear transformations, and ...
Transformed generalized linear models
(ELSEVIER SCIENCE BV, 2009)
The estimation of data transformation is very useful to yield response variables satisfying closely a normal linear model, Generalized linear models enable the fitting of models to a wide range of data types. These models ...
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 ...
Representation of transmission lines in modal domain using analytical transformation matrices
(2011-05-31)
The phases of a transmission line are tightly coupled due to mutual impedances and admittances of the line. One way to accomplish the calculations of currents and voltages in multi-phase lines consists in representing them ...
VAr planning using genetic algorithm and linear programming
(2001-05-01)
A combined methodology consisting of successive linear programming (SLP) and a simple genetic algorithm (SGA) solves the reactive planning problem. The problem is divided into operating and planning subproblems; the operating ...
Analysis of exact linearization and aproximate feedback linearization techniques
(Brasil, 2011)
This paper presents a study of linear control systems based on exact feedback linearization and approximate feedback linearization. As exact feedback linearization is applied, a linear controller can perform the control ...
