The engineering and construction of a pre-bunched free electron maser
(EMW Publishing, 2009)
We are developing prototype free electron maser (FEM) that is compact, tuneable and efficient for potential industrial use. Therefore we define the characteristics for the construction of a novel X-band rectangular waveguide ...
Low power reconfigurable sub-band filter bank ASIC for MP3 decoder
(Inderscience Enterprises Limited, 2009)
There is an ever demanding need to develop low power audio devices using MP3
technology. From the profiled results of MP3 algorithm on ARM processors, it has been
observed that the synthesis filter bank in the audio ...
New design of spectral amplitude coding in OCDMA with zero cross-correlation
(Elsevier B.V. (Imprint: NORTH-HOLLAND), 2009-07)
A zero cross-correlation (ZCC) code is proposed to reduce the impact of system impairment and multiple access interference (MAI) in spectral amplitude coding optical code division multiple access (SAC-OCDMA) system. ...
Low-power H.264 video compression architectures for mobile communication
(Institute of Electrical and Electronics Engineers (IEEE), 2009-09)
This paper presents a method to reduce the computation and memory access for variable block size motion estimation (ME) using pixel truncation. Previous work has focused on implementing pixel truncation using a fixed-blocksize ...
Brain machine interface: A comparison between fuzzy and neural classifiers
(ICIC International, 2009)
Patients with neurodegenerative disease loose all motor movements including impairment of speech, leaving the patients totally locked-in. One possible option for rehabilitation of such patients is through a brain machine ...
Nano-silver microcavity enhanced UV GaN light emitter
(Inderscience Enterprises Limited, 2009)
We report results of measurements that help to clarify the role of silver in the reflection of UV emission light from GaN. A GaN as an active layer was sandwiched between two silver metal reflectors. GaN layer on sapphire ...
Biological kinetics evaluation of anaerobic stabilization pond treatment of palm oil mill effluent
(Elsevier Ltd., 2009-11-21)
Biological kinetic (bio-kinetic) study of the anaerobic stabilization pond treatment of palm oil mill effluent (POME) was carried out in a laboratory anaerobic bench scale reactor (ABSR). The reactor was operated at different ...
A platform to develop a secure instant messaging using jabber protocol
(Science Publications, 2009)
Problem statement: Open Source technologies are interesting in that they allow free experimentation and integration by anyone and anywhere. A Jabber user can control presence with very little effort. Another user, regardless ...
Core nucleus dynamics in Λ hypernuclei
(World Scientific Publishing Co, 2009-06)
We develop a Thomas Fermi theory to study the core polarization effects in Λ hypernuclei. Nuclei in the range of 10B to 243Am are included. Core polarization energies and changes in rms radii due to presence of Λ are ...
The effects of compiler optimizations on embedded system power consumption
(Inderscience Enterprises Limited, 2009)
Power consumption is a subject of serious consideration in embedded systems design because embedded systems are constrained to stringent power and energy requirements. The mission of lowering power consumption and energy ...
