Influência da anodização pulsada nas propriedades da alumina anódica porosa (AAP)
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Ciência dos Materiais - PPGCM-SoCâmpus Sorocaba, 2017-04-27)
Porous anodic alumina can be obtained, in addition to conventional methods such as potentiostatic and galvanostatic, or by pulsed method. Among these are the methods of discontinuous pulse, hybrid pulse and polarized pulse ...
Suppressing the effect of ICI power using dual sinc pulses in OFDM-based systems
(Elsevier, 2016)
Sensitivity to frequency offset in orthogonal frequency division multiplexing (OFDM)-based systems allow unwanted interference among the subcarriers, which results in intercarrier interference (ICI). A novel family of ...
Generalization of the Y-differential autotransformer for 12- and 18-pulse converters
(Elsevier B.V., 2006-03-01)
This work proposes a methodology to generalize the Y-connections for 12- and 18-pulse autotransformers. A single mathematical expression, obtained through simple trigonometric operations, represents all the connections. ...

Improved Nyquist-I Pulses to Enhance the Performance of OFDM-Based Systems
(Springer, 2017)
Pulse shaping is used in orthogonal frequency division multiplexing (OFDM) based systems to reduce inter-carrier interference (ICI) power and peak-to-average power ratio (PAPR), which are considered the major weaknesses ...
