Mutual coupling modeling in transmission lines directly in the phase domain
(2011-12-12)
This paper describes a computational model based on lumped elements for the mutual coupling between phases in three-phase transmission lines without the explicit use of modal transformation matrices. The self and mutual ...
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 ...
Achieving Superior Motivation and Performance: The Case of the Acquisition and Transformation of CAZEL in Mexico
(Journal of Enterprise Transformation, 2014-01-06)
This article explores some of the prevailing change management methodologies to determine their applicability and convenience as transformational tools. The authors propose a practical model for change and explore the ...
A Practical Approach to Business Transformation: The Case of the Telecommunication Services of Trinidad and Tobago
(Journal of Enterprise Transformation, 2013-01-28)
This article outlines a novel, practical, and comprehensive business transformation model using a continuous life-cycle approach applied to three dimensions of a business (processes, people, and technology). It was used ...
Método de transformação de modelos de processos de negócio para diagramas de classes de análise
(Universidade Tecnológica Federal do ParanáPonta GrossaBrasilPrograma de Pós-Graduação em Ciência da ComputaçãoBrasil, 2019-04-18)
Business process modeling is an important step in the identification of system requirements, which is also the basis for modeling the system. However, difficulties are encountered when performing the transformation of the ...
Analyses of the Spurious Oscillations in the Lumped Parameters Line Model
(Ieee-inst Electrical Electronics Engineers Inc, 2015-07-01)
The currents and voltages in the multiphase transmission line are described by differential equations that sometimes can be difficult to solve due the mutual coupling and skin effect that have to be considered for accurate ...
Proposal of a simplified process to correct the phase decoupling using modal analysis
(2012-12-11)
Modal analysis is widely approached in the classic theory of transmission line modeling. This technique is applied to model the three-phase representation of conventional electric systems taking into account their self and ...
Comparative analysis of synchronization algorithms based on PLL, RDFT and Kalman Filter
(2007-12-01)
This paper discusses the main characteristics and presents a comparative analysis of three synchronization algorithms based respectively, on a Phase-Locked Loop, a Kalman Filter and a Discrete Fourier Transform. It will ...

Construction of type-II Bäcklund transformation for the mKdV hierarchy
(2015-09-14)
From an algebraic construction of the mKdV hierarchy we observe that the space component of the Lax operator plays the role of a universal algebraic object. This fact induces the universality of a gauge transformation that ...
