Analysis of Bulk Second-Order Ferroelectric Switching in Oscillatory Dynamical System
(Kolej Universiti Kejuruteraan Utara Malaysia, 2004)
A detailed analysis of polarization reversal in bulk for second-order ferroelectric (FE) phase transition material in the framework of the Landau model is presented. We focus on the changes of polarization P and its switching ...
The physics of Tsunami: basic understanding of the Indian Ocean disaster
(Science Publications, 2005)
This study gives a simple physics explanation behind the Indian Ocean earthquake, called December 26th‘s Tsunami. The explanation based on physics energy conservation and wave properties have been used to understand this ...
A development of fractal PIFA (Planar Inverted F Antenna) with bandwidth enhancement for mobile phone applications
(Institute of Electrical and Electronics Engineering (IEEE), 2009-11-16)
A novel Fractal planar inverted F antenna (F-PIFA) based on the self affinity design is presented in this paper. The procedure for designing a Fractal Planar Inverted F Antenna is explained and the 2nd iteration of Sierpinski ...
Design of pyramidal microwave absorber using agriculture waste with different resin content percentage
(Universiti Malaysia Pahang (UMP), 2009-06-20)
Agriculture waste has many potential
to produce an alternative and beneficial product
for any suitable application such as microwave
absorber for anechoic chamber. In this work,
agriculture waste like rice husk from ...
The effect of conductor line to meander line antenna design
(Institute of Electrical and Electronics Engineering (IEEE), 2008)
In this paper, the meander line antenna (MLA) have been designed to operate at 2.4-GHz for WLAN application. Two different designs of meander line antenna are investigated, without conductor line and with conductor line. ...
Design of split ring resonator filters for interference suppression in UWB
(Institute of Electrical and Electronics Engineering (IEEE), 2008-12-02)
Microstrip stop-band filters based on complementary split ring resonators has been proposed in this project. Two shapes (circle and square) of SRRs have been investigated to come out device which is designed to suppress ...
A dual band planar monopole antenna with inverted-M parasitic plane
(Institute of Electrical and Electronics Engineering (IEEE), 2007)
Introduction of parasitic plane as additional radiator helps to produce desired resonant frequencies, while helping to minimize the size of the antenna. A dual-band monopole antenna with parasitic plane is designed to ...
Design of a modified L-shaped bandstop filter for UWB applications
(Institute of Electrical and Electronics Engineering (IEEE), 2009-11-03)
Performance of UWB system may be degraded since the interference may be exist due to the presence of signals from other existing wireless communication systems. Currently, the major interference are in-band signal from ...
Oxidation behaviour of low carbon steel in natural water
(Oriental Science Publishing Co, 2002)
Natural water pollution has been identified as a potential danger to metallic materials used under service conditions. Sea water and lake water foulants have adequate corrosive environment due to chemical ingredients ...
Active stereo vision based system for estimation of Mobile Robot Orientation using composition matrix
(Universiti Malaysia Perlis, 2009-10-11)
The computation of a mobile robot position and orientation is a common task in the area of computing vision and image processing. For a successful application, it is important
that the position and orientation of a mobile ...
