Performance of random diagonal code for OCDMA systems using new spectral direct detection technique
(Elsevier Inc., 2009-06)
This paper studies the performance of random diagonal (RD) code for spectral-amplitude coding OCDMA (SAC-OCDMA) system using a newly proposed spectral direct detection technique. RD code is constructed using code segment ...
The effect of heat treatment on the open circuit potential of magnesium sacrificial anode
(University of Malaya, 2009)
Magnesium sacrificial anode that possess high value of open circuit potential, Eoc is needed as it can protect larger area of underground metal structure in cathodic protection. Solution treatment was applied on magnesium ...
Structural, elastic, electronic, optical and thermal properties of c-SiGe2N4
(Springer Verlag, 2009-09)
We have investigated the structural, elastic, electronic, optical and thermal properties of c-SiGe2N4 by using the ultrasoft pseudopotential density functional method within the generalized gradient approximation. The ...
An investigation on visual and audiovisual stimulus based emotion recognition using EEG
(Inderscience Enterprises Ltd., 2009-01)
In this paper, we investigate the possibility of using visual and audio visual stimulus for detecting the human emotion by measuring electroencephalogram (EEG). Visual and audiovisual stimulus based protocols is designed ...
Identification of LPI radar signals by higher order spectra and neural network techniques
(Inderscience Publishers, 2009)
LPI radars use continuous wave, wide bandwidth low power signals of the order of a few watts making its detection difficult. The important advantage of LPI radar is to go undetected, while maintaining a strong battlefield ...
PCB inspection for missing or misaligned components using background subtraction
(World Scientific and Engineering Academy and Society (WSEAS) Press, 2009)
Automated visual inspection (AVI) is becoming an integral part of modern surface mount technology (SMT) assembly process. This high technology assembly, produces printed circuit boards (PCB) with tiny and delicate electronic ...
Fast transient solution of a two-layered counter-flow microchannel heat sink
(Emerald Group Publishing Limited., 2009)
Purpose: The purpose of this paper is to apply asymptotic waveform evaluation (AWE) to the transient analysis of a two-layered counter-flow microchannel heat sink. Design/methodology/approach: A two-layered counter-flow ...
Vowel recognition based on frequency ranges determined by bandwidth approach
(Institute of Eelectrical and Electronics Engineering (IEEE), 2009-07)
Automatic speech recognition (ASR) has made great strides with the development of digital signal processing hardware and software especially using English as the language of choice. In this paper, a new feature extraction ...
Design and analytical modeling of folded waveguide traveling wave tube
(Elsevier B. V., 2009-12-21)
We are developing a simple analytical model for the design of the folded waveguide traveling wave tube (FWTWT). Numerical software does exist for the design of FWTWT but requires large computer run time, is costly and does ...
Three-axis fuzzy variable structure control with an application to micro satellite
(IEEE, 2009-12-10)
This paper presents a hybrid form of three-axis control system with has both Variable Structure Control (VSC) and Fuzzy Logic Control (FLC). This proposed Fuzzy Variable Structure Control (FVSC) approach combines the power ...
