A lower bound for the energy of symmetric matrices and graphs
(2017)
The energy of a symmetric matrix is the sum of the absolute values of its eigenvalues. We introduce a lower bound for the energy of a symmetric matrix partitioned into blocks. This bound is related to the spectrum of its ...

Clarke's matrix correction procedure for non transposed three-phase transmission lines
(2008-09-29)
Clarke's matrix has been applied as a phase-mode transformation matrix to three-phase transmission lines substituting the eigenvector matrices. Considering symmetrical untransposed three-phase lines and the frequency range ...
Routine for Simulating Transmission Lines with Symmetrical and Asymmetrical Configurations Using a Real and Constant Modal Transformation Matrix
(Ieee, 2018-01-01)
Modal analysis is widely used in over-voltage and over-current studies of power systems. Modal transformation decouples a transmission line into its modes. Time-domain transmission line models usually require a real and ...
