Two digital filtering algorithms for fast estimation of symmetrical components in a power system: A static estimation approach
(
Elsevier
, 2003 , Article)
This paper presents the application of two digital filters working together for fast estimation of power systems symmetrical components. The three-phase unbalanced system is transformed to two phases using α–β-transformation. ...
Temperature and electric field effects on the dielectric dispersion of modified polyvinyl chloride
(
Elsevier
, 2003 , Article)
The effect of electric field on the dielectric dispersion of modified polyvinyl chloride (PVC) has been investigated. The applied direct current (DC) field strength was ranging from 0 to 104 V cm−1. The complex permitivity ...
Ion beam modification of surface properties of polyethylene
(
Elsevier
, 2003 , Conference Paper)
Improvement of polymer tribological properties is an essential issue for their application when used as parts of machines or artificial human joints. Ion implantation is a very promising technique in this respect. This ...
Mechanical and thermal properties of gamma-ray irradiated polyethylene blends
(
Elsevier
, 2003 , Conference Paper)
In this work, the results obtained by gamma-ray irradiation of polyethylene (PE) blends are presented. The blends were produced by injection molding at 220°C with different compositional ratios, i.e. 100/0, 15/85, 25/75, ...
