Design of single layered circular and rectangular U-slotted, CPW-fed antennas and arrays for RFID applications
(Institute of Electrical and Electronics Engineers (IEEE), 2010-05-26)
This work describes the design of high gain, U-slot antennas for RFID 915 MHz (902-
928 MHz) applications. Four types of antenna were designed, optimized and evaluated -
a circular, U-slotted antenna, a rectangular ...
Modelling and simulation of a 1.6 Tb/s optical system based on multi-diagonal code and optical code-division multiple-access
(Institute of Physical Optics, 2012)
n this paper we have modelled and simulated a 1.6 Tb/s (100×16 Gb/s) optical system based on spectral amplitude coding for the optical code-division multiple- access (SAC-OCDMA) scheme. In order to reduce the effect of ...
Illumination and contrast correction strategy using bilateral filtering and binarization comparison
(Universiti Teknikal Malaysia Melaka, 2016)
Illumination normalization and contrast variation on images areone of themost challenging tasks in the imageprocessing field. Normally, the degrade contrast imagesarecaused by pose, occlusion, illumination,and ...
Lipase production from Jatropha curcas solid waste
(Universiti Malaysia Perlis (UniMAP), 2010-10-16)
Lipases produced by using agro-industrial residual or waste as substrate become interesting topic among the researchers. The aim of this study was to produce lipases by valorization the Jatropha solid waste as substrate ...
Legitimacy of the Malays as the Sons of the Soil
(Canadian Center of Science and Education, 2012-12-31)
This paper presents evidence to defend the Malay as legitimate sons of the soil. The arguments are supported by
linguistic, archeological, paleoanthropological, prehistorian, botanical, genetic and forensic evidence. The ...
A Simple Method for the Production of Pure Crystalline Silica from Lemon Grass
(North Carolina State University, 2016)
Lemon grass is an inexpensive raw material that can be used to produce natural silica. A method using hydrochloric acid (HCl) leaching followed by thermal combustion at 600 °C was developed to produce purified silica from ...
Behavior of CuPb12Sn6 Alloys subjected to Heat Treatments
(EDP Sciences, 2016-10)
The paper present the structural modifications induced by 3 heat treatments: homogenization, recrystallization and quenching, respecting the specific parameters of copper based alloys. The obtained modifications by heat ...
Site-specific evaluation of a MIMO channel capacity for multi-antenna mobile terminals in proximity to a human hand
(The European Association on Antennas and Propagation (EurAAP), 2011-04-10)
This paper presents a comprehensive evaluation on the Multiple-Input Multiple-Output (MIMO) channel capacity performance of a coupling element -based multi-antenna structures on a mobile terminal at the 2000 MHz Universal ...
Setup and results of pyramidal microwave absorbers using rice husks
(EMW Publishing, 2011)
Agricultural wastes are considered not useful and are commonly dumped or burned after crop harvesting. Rice husks from paddy (Oryza sativa) are example of agricultural wastes. Rice husks have been investigated as the ...
Ambiguity analysis of isolation - Based multi-antenna structures on mobile terminal
(Institute of Electrical and Electronics Engineering (IEEE), 2011-04-10)
This paper presents a comprehensive numerical study on the ambiguities for different isolation-based multi-antenna structures. The focus is on four-element planar inverted-F antennas (PIFA) array on a typical 100mm 40mm ...
