Improved lumped models for transient heat conduction in a slab with temperature-dependent thermal conductivity
(ElsevierBrasilNúcleo Interdisciplinar de Dinâmica dos Fluidos, 2019)
Study of the electrical conduction process in natural rubber-based conductive nanocomposites filled with cellulose nanowhiskers coated by polyaniline
(2021-03-01)
In the present work, the electrical properties of a natural rubber-based nanocomposite (NR) filled with cellulose nanowhiskers (CNW) coated with polyaniline (PANI) were studied. We developed a statistic model that simulates ...
Study of charge transport in blends of natural rubber and poly(o-methoxyaniline) based on a resistor network statistical model
(Elsevier B.V. Sa, 2009-11-01)
A statistical model of a resistor network is proposed to describe the electrical properties, real and imaginary components of ac conductivity, of natural rubber (NR) and poly(o-methoxyaniline) (POMA) blend. It takes into ...

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 ...
Ionospheric conductance using different IRI F2 layer models
(Elsevier, 2021-11)
The conductivity is an important ionospheric parameter since it define the current systems in the high atmosphere and the magnetosphere. As direct estimation of conductivity in real time is not possible, it is estimated ...
