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 ...
Barrett's Esophagus Identification Using Color Co-occurrence Matrices
(Ieee, 2018-01-01)
In this work, we propose the use of single channel Color Co-occurrence Matrices for texture description of Barrett's Esophagus (BE) and adenocarcinoma images. Further classification using supervised learning techniques, ...
Shear modulus G(0) and its correlations with matric suction, unconfined compression strength and tensile strength of an unsaturated residual soil
(Ios Press, 2015-01-01)
Several studies have been developed aiming to understand the behavior of saturated natural soils under small strains. A few studies have considered unsaturated soils, in most cases compacted soils and, eventually, disregarding ...
A hybrid method for the solution of a sparse power system matrices on vector computers
(I E E E, 1996-01-01)
This paper describes a methodology for solving a linear system of equations on vector computer. The methodology combines direct and inverse factors. The decomposition and implementation of the direct solution in a CRAY ...
Development of a set of matrices for the evaluation and classification of regional clusters
(European Operations Management AssociationGlasgow, UK, 2006-06-18)
This study presents the development of a set of matrices to evaluate regional clusters according to the perspective of their different characteristic dimensions.
Two applications of this set were studied. The former ...
Eigenvalue analyses for non-transposed three-phase transmission line considering non-implicit ground wires
(2012-12-11)
This paper presents a method for analyzing electromagnetic transients using real transformation matrices in three-phase systems considering the presence of ground wires. So, for the Z and Y matrices that represent the ...
STOCHASTIC MATRICES AS A TOOL FOR BIOLOGICAL EVOLUTION MODELS
(World Scientific Publ Co Pte Ltd, 2010-01-01)
A simple model is set forth in which discrete changes in the statistical distribution of various features are treated by means of stochastic matrices, which transform one probability distribution into another one. A few ...
