Ethanol fuel analysis by time-domain reflectometry
(Rio de Janeiro, 2014-03-24)
The technique of Time Domain Reflectometry
(TDR) is applied for qualifying ethanol adulterated with water
and / or methanol. We used the commercial TDR model VG400,
which was originally developed for determining soil ...
Applying MDE tools to defining domain specific languages for model management
(Sociedad Argentina de Informática e Investigación Operativa, 2013-09)
In the model driven engineering (MDE), modeling languages play a central role. They range from the most generic languages such as UML, to more individual ones, called domain-specific modeling languages (DSML). These languages ...
Simultaneous FETI and block FETI: Robust domain decomposition with multiple search directions
(Wiley, 2015)
Domain decomposition methods often exhibit very poor performance when applied to engineering problems with large heterogeneities. In particular, for heterogeneities along domain interfaces, the iterative techniques to solve ...
An alternative procedure to decrease the dimension of the frequency dependent modal transformation matrices: Application in three-phase transmission lines with a vertical symmetry plane
(2006-12-01)
The objective of this paper is to show an alternative representation in time domain of a non-transposed three-phase transmission line decomposed in its exact modes by using two transformation matrices. The first matrix is ...

A Grounding System Model Directly in Time-Domain
(2016-10-01)
This work presents a technique for electrical grounding system representation, directly in the time domain. It is based on the theory of least squares and starts from harmonic grounding impedance, representing it by discrete ...
Characterization of transmission lines based on frequency-domain and time-domain measurement techniques
(Universidade Tecnológica Federal do ParanáCuritibaBrasilMestrado em Engenharia Elétrica e Informática IndustrialUTFPR, 2018-05-21)
The importance of electrical cables in modern data communication and power transmission systems cannot be overstated. Efficient and secure transmission of either data or energy depends on the healthy state of electrical ...
Self-reliant detection of route leaks in inter-domain routing
(2015)
Route leaks are among the several inter-domain routing anomalies that have the potential to cause large scale service disruptions on the Internet. The reason behind the occurrence of route leaks is the violation of routing ...
