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 ...
PWM Method to Eliminate Power Sources in a Nonredundant 27-Level Inverter for Machine Drive Applications
(IEEE, 2009)
A nonredundant three-stage 27-level inverter using ldquoHrdquo converters is analyzed for medium- and high-power machine drive applications. The main advantage of this converter is the optimization of levels with a minimum ...
Pulsed Nd:YAG laser welding of UNS S 32205 duplex stainless steel
(2016-01-01)
This paper reports an experimental study of laser welding on duplex stainless steel UNS S32205 employed in the oil and natural gas industries. A pulsed Nd:YAG laser was used to weld the specimens. Bead on plate condition ...

Subsiding OOB Emission and ICI Power Using iPOWER Pulse in OFDM Systems
(Univ Suceava, Fac Electrical Eng, 2016)
A novel family of Nyquist-I pulses called iPOWER is proposed with a new design parameter. that provides an extra degree of freedom for a certain roll-off factor, a. The proposed pulse is examined and compared with other ...
Single camera time-resolved 3D tomographic reconstruction of a pulsed gas jet
(Springer, 2013-11)
Experimental characterization of micro-jets is challenging because of the small dimensions of the micro-nozzle. In this study, we propose a new technique to visualize the instantaneous 3D structure of a pulsed gas micro-jet. ...
