Fractal approach to ac impedance spectroscopy studies of ceramic materials
(2001-11-01)
A novel fractal model for grain boundary regions of ceramic materials was developed. The model considers laterally inhomogeneous distribution of charge carriers in the vicinity of grain boundaries as the main cause of the ...
Detecting and sorting the paradoxes associated with smartphone use by Brazilian professionals
(Americas Conference on Information Systems, 2015)
The use of mobile wireless technologies brings associated paradoxes already identified in the literature. Thus, this research uses quantitative analysis to determine the perception of presence and intensity level of fourteen ...
