Uninterruptible power supply monitoring system with Visual Basic
(Universiti Malaysia Perlis, 2006-12-29)
In industrial process today, reliability of equipment is very important. Power supply must be able to cater the need of industrial process. In case of power failure, backup power supply system must be able to support the ...
FPGA based SPWM Bridge Inverter
(Science Publications, 2007)
This study presents methodology to generate sinusoidal pulse width modulation (SPWM)
signal using Field Programmable Gate Array, FPGA technology. We discussed the unipolar switching scheme and the methodology to generate ...

Dual frequency integrated antenna (DFIA) with image rejection
(Institute of Electrical and Electronics Engineers (IEEE), 2005)
A new configuration of integrated antenna featuring dual frequency operations and image frequency rejection is implemented. The used of dual frequency for image rejection in one system by using one antenna is a new technique ...
The surface morphology characterization of electroless nickel immersion gold under bump metallurgy (UBM) using SEM
(American Institute of Physics, 2007-05-09)
This paper presents the surface morphology characterization at each process step in electroless nickel immersion gold (ENIG) deposition using Scanning Electron Microscope (SEM). The characterization start at initial bond ...
