Comparative study between measurement and predictions using geometrical optics and uniform theory of diffraction for case of non-line-of-sight (NLOS) in indoor environment
(Springer Science+Business Media New York, 2013-08)
This paper describes the investigation and comparison of the accuracy of a deterministic model for a WLAN system in the indoor environment. The measurement system consisted of a spectrum analyzer and a log-periodic antenna. ...
Modeling of coaxial slot waveguides using analytical and numerical approaches: Revisited
(Hindawi Publishing Corporation, 2012)
Our reviews of analytical methods and numerical methods for coaxial slot waveguides are presented. The theories, background, and physical principles related to frequency-domain electromagnetic equations for coaxial waveguides ...
Experimental determination of the performance of rice husk-carbon nanotube composites for absorbing microwave signals in the frequency range of 12.4-18 GHz
(EMW Publishing, 2013)
Composites of rice husks and carbon nanotubes (RHC-NTs) are an innovation in improving the absorption of microwave signals. Rice husks, which are an agricultural waste material, have been found to possess a significant ...
Modelling of multi-axial ultimate elastic wall stress (UEWS) test for glass fibre reinforced epoxy (GRE) composite pipes
(Trans Tech Publications, 2013)
This paper describes the modeling of multiaxial ultimate elastic wall stress (UEWS) at room temperature for glass fibre reinforced epoxy (GRE) composite pipes. The model developed, predicts the stress-strain response caused ...
In vitro evaluation of finger's hemodynamics for vein graft surveillance using electrical bio-impedance method
(American-Eurasian Network for Scientific Information (AENSI), 2014-03)
Electrical bio-impedance measurement has great potential in many biomedical applications including vein graft surveillance. Studies have shown that thrombosis was
the major cause of the vein graft failure. The meticulous ...
CFD analysis on mismatched end-to-end internal diameter of RSVG Models
(American-Eurasian Network for Scientific Information (AENSI), 2014-03)
A digital arterial disease in upper extremity is uncommon happened compare to arterial
disease in lower extremity. A surgical vein graft interposition is performed as
revascularization procedure. However, mismatching ...
Optical properties of ultraphosphate glasses containing mixed divalent zinc and magnesium ions
(Elsevier B.V., 2013-01)
Ternary zinc magnesium ultraphosphate glasses corresponding to (ZnO)x
(MgO)30 x
(P2O5)70 were
prepared by melt quenching technique in the range of 5 6 x 6 20 mol%. The optical absorption spectra
of the glasses were ...
Dielectric spectroscopy of pharmaceutical drug (Paracetamol) dosage in water
(IEEE Conference Publications, 2013-12)
This paper discuss about the dielectric measurement on different concentration of pharmaceutical drug using Agilent 85070E High-Temperature and Slim form probe. A microwave dielectric measurement is set up to measure dosage ...
Rubber tire dust-rice husk pyramidal microwave absorber
(EMW Publishing, 2011)
Rubber tire dust-rice husk is an innovation in improving the design of pyramidal microwave absorbers to be used in radio frequency (RF) anechoic chambers. An RF anechoic chamber is a shielded room covered with absorbers ...
