Instants messaging clients - relaxed, free & enjoyable English learning and training tools
(Kolej Universiti Kejuruteraan Utara Malaysia, 2006)
In a demanding world of using English as a second language, computer technology and the Internet are being dominantly used as they provide incridible boost to language learning environment. At present, we can experience ...
Effects of calcination temperature and zinc-source concentration on chemical-solution synthesized ZnO nanorods
(Electrochemical Society, 2006)
In this paper, ZnO nanoparticles, in particular nanorods, were prepared by a time-saving and a cost effective chemical-solution process. Zinc acetate dehydrates, 2-propanol and diethanolamine were used as the source to ...
Reproducibility of silicon single electron quantum dot transistor
(Nano Science and Technology Institute, 2006)
In principle, based on the form of tunnel junction, single electron transistor (SET) can be classified into four types, i.e. nanowire SET, quantum dot SET, nanotube SET and point contact SET. Another classification is SET ...
Extraction mechanism of Gd3+ by BTMPPA
(Elsevier, 2006)
The extraction behavior of Gd(III) from acidic nitrate-acetato medium by bis(2,4,4-trimethylpentyl)phosphinic acid (BTMPPA, H2A2) in toluene either alone or in combination with trioctylphospine oxide (TOPO, B) has been ...
Estimation of missing values for air pollution data using Interpolation technique
(Universiti Malaysia Perlis, 2006)
Air pollution data such as PM10, sulphur dioxide, ozone and carbon monoxide are usually obtained using automated machines located at different sites. These are usually due to mechanical failure, routine
maintenance, changes ...
Design and fabrication of Microfluidic devices: MOSFET & Capacitor
(Institute of Electrical and Electronics Engineers (IEEE), 2006)
Microfluidic devices, based on silicon, are fabricated by photolithography, wet chemical etching with focus on an liquid conduction channel n-channel depletion MOSFET and a silica-liquid dielectric capacitor. Masks for ...
Growth of GaN quantum dots using [(C2H5)4]Si by plasma assisted MOCVD
(Institute of Electrical and Electronics Engineering (IEEE), 2006-07)
Growth of GaN quantum dots on AlGaN layer using [(C2H 5)4]Si [TESi] by plasma assisted metal organic chemical vapor deposition (PA-MOCVD) is reported. The surface profile of the grown GaN quantum dot was determined by ...
The characterization of power supply noise for optical mouse sensor
(Institute of Electrical and Electronics Engineering (IEEE), 2006)
The induced power supply noise (sinusoidal waveform) that injected to Vdd pin will cause unwanted spike at the positive amplitude and negative amplitude to the DC input voltage. At certain limit this spike will cause the ...
Characterization of robust alignment mark to improve alignment performance
(Institute of Electrical and Electronics Engineering (IEEE), 2006)
Overlay requirement is one of the biggest obstacles in achieving a very small feature. With the continued growth of small feature size, overlay requirement becomes tighter. Such a tight requirement requires a very high ...
Characteristics of Serial Peripheral Interfaces (SPI) timing parameters for optical mouse sensor
(Institute of Electrical and Electronics Engineering (IEEE), 2006)
In this paper we report the characterizations results of Serial Peripheral Interface (SPI) timing parameters for optical mouse sensor. SPI is an interface that facilitates the transfer of synchronous serial data. It supports ...
