Computation of stress intensity factor for multiple cracks using singular finite element
(International Association of Computer Science and Information Technology (IACSIT), 2011-03-25)
The simplification of two dimensional approaches in singular finite elements has promoted the method to be used in the formulation of stress intensity factor (SIF) of multiple cracks in finite body. The effect of shielding ...
Harmonic monitoring at UniMAP distributed campus
(Institute of Electrical and Electronics Engineers (IEEE), 2011-06-06)
This paper an attempt has been made to monitor and analyze the harmonic distortions caused by certain typical non linear loads of an educational institution. The current and voltage harmonic distortion at PCC feeding office ...
Spectral efficiency of unipolar SAC-OCDMA system considering noise effects
(Institute of Electrical and Electronics Engineers (IEEE), 2011-09-25)
In this paper, we evaluate the spectral efficiency of unipolar spectral-amplitude coding optical code-division multiple access (SAC-OCDMA) system operating with incoherent sources in the present of intensity, shot, and ...
Improvement of induction machine performance using power factor correction
(Institute of Electrical and Electronics Engineers (IEEE), 2011-06-21)
In this paper, a new approach to improve power factor (PF) and reduced total harmonic distortion (THDi) is generated by a single phase induction motor is proposed. By designing the necessary technique and methodology, the ...
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 ...
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 ...
Design of a Flexible Minkowski-Like Pre-Fractal (MLPF) antenna with different ground planes for VHF LMR
(City University of Hong Kong, 2011-03-07)
This work investigates the suitability of a flexible Minkowski-like pre-fractal antenna (MLPF) for
application in the Very High Frequency (VHF) Land and Mobile Radio (LMR) frequency bands (136-174 MHz). The
proposed ...
Design and fabrication of a flexible Minkowski fractal antenna for VHF applications
