Three-Dimensional Imaging and Analysis of Electrical Trees
(2014)
Electrical trees are micrometre-size tubular channels of degradation in high voltage polymeric insulation, a precursor to failure of electrical power plant. Hence, electrical trees critically affect the reliability of power ...
Electrical conductivity of hydrophobically modified polyelectrolytes in methanol/water solution
(2003)
Measurements of the electrical equivalent conductivity of potassium salts of poly(maleic acid-co-1-olefins), PA-nK(2) with n = 12, 18 has been carried out in methanol-water mixtures in the whole range of composition. The ...
Electric field and magnetometer observations of the equatorial electrojet: An IEEY program
(Instituto Geofísico del Perú, Radio Observatorio de Jicamarca, 1994)
As part of the IEEY program, a chain of magnetometers was deployed along the Peruvian sector crossing the equatorial electrojet. Simultaneous vertical drift measurements were made using Jicamarca's normal I.S. F-region ...
Fast Calderón Preconditioning for the Electric Field Integral Equation
(IEEE, 2019)
Despite its solid mathematical background, the standard Calderón preconditioning for the electric field integral equation scales poorly with respect to the mesh refinement due to its construction over barycentric meshes. ...
Detecção de defeitos em motores de indução pela análise da assinatura da corrente elétrica
(Universidade Tecnológica Federal do ParanáCuritibaDepartamento Acadêmico de Eletrotécnica, 2015-02-09)
With the growth of global competitiveness and the consequent search for costs reduction and increase in productivity of the industrial actives there is a need, in the field of electrical engineering, of obtaining bigger ...
A fractal model for the electrical conductivity of water-saturated porous media during mineral precipitation-dissolution processes
(Elsevier, 2020-11)
Precipitation and dissolution are prime processes in carbonate rocks and being able to monitor them is of major importance for aquifer and reservoir exploitation or environmental studies. Electrical conductivity is a ...
Utilization of neuromuscular electrical stimulation in the acute phase of ankle immobilization at 90°: Study in rats
(2009-06-25)
Objective: To evaluate the skeletal muscle glycogen content and plasmatic concentration of interleukin -6 (IL-6), interleukin-4 (IL-4), interleukin-10 (IL-10) and tumor necrosis factor-alpha (TNF-α) in rats submitted to ...
