Modal decoupling of overhead transmission lines using real and constant matrices: Influence of the line length
(2017-11-01)
The Clarke's matrix is a well-known real and constant transformation matrix used for modal transformation in three-phase transmission lines modeling. Although modal analysis has been widely discussed in the technical ...
Identification of transmission line parameters from temporal measurements of currents and voltages in their terminals: Influence oh the length line
(2012-12-11)
The objective of this paper is to show a methodology to estimate transmission line parameters. The method is applied in a single-phase transmission line using the method of least squares. In this method the longitudinal ...

Increasing the lateral line length of drip irrigation systems
(2013)
Aims: The hypothesis of this research is that it is possible to increase the drip irrigation lateral line length by using a larger spacing between emitters at the beginning of the lateral line and a smaller one after a ...
Primary tooth length determination in direct digital radiography: An in vivo study
(2007-11-01)
Purpose: The purpose of this in vivo study was to compare the accuracy of primary incisor length determined by direct digital radiography (straight-line measurement and grid superimposition) and measurement of the actual ...

A new procedure to derive transmission line parameters: Theoretical considerations
(2005-10-31)
The objective of this paper is to show an alternative methodology to calculate transmission line parameters per unit length. With this methodology the transmission line parameters can be obtained starting from the phase ...

Mathematical models to optimize lateral line length using two spacing between drippers
(2014-01-01)
In drip irrigation systems, longer lateral lines can provide cost reduction, but it is limited by the required irrigation uniformity. Non-pressure compensating drip hose is widely used for vegetables and orchards irrigation ...
