Implementation and Analysis of Reward Functions under Different Traffic Models for Distributed DSA Systems
(
IEEE
, 2015 , Article)
In this paper, we implement and analyze a resource allocation protocol for distributed dynamic spectrum allocation (DSA) systems. The DSA protocol is a learning-based protocol that allows secondary users (SU) to exploit ...
Ultrasonic and thermal properties of γ-irradiated low-density polyethylene
(
John Wiley & Sons, Inc.
, 1993 , Article)
The ultrasonic pulse-echo technique and differential thermal analysis were utilized to characterize and to monitor the effect of ?-irradiation on the sonic modulus and the heat effect of low-density polyethylene. The sonic ...
Photodegradation of methylene blue dye by the UV/H2O2 and UV/acetone oxidation processes
(
Elsevier B.V.
, 2005 , Article)
The photodegradation of methylene blue (MB) dye in aqueous solutions was investigated using a laboratory-scale UV lamp in the presence of hydrogen peroxide (H2O2). Different initial concentrations of dyes (10, 20, 30, 40 ...
Beamforming OFDM Performance under Joint Phase Noise and I/Q Imbalance
(
IEEE
, 2015 , Article)
Phase noise (PHN) and in-phase/quadrature (I/Q) imbalance are two major RF impairments in direct-conversion wireless transceivers. Beamforming and orthogonal frequency division multiplexing (OFDM) schemes have been adopted ...
Properties of Dialkylcarbonate + 1-Alkanol Mixtures at the Vacuum Interface
(
American Chemical Society
, 2016 , Article)
The properties of solutions formed by dialkylcarbonate + 1-alkanol solutions are studied using classic molecular dynamics simulations. The effects of solution composition, temperature, and dialkylcarbonate type have been ...
Greenhouse gas (GHG) emissions in the Sultanate of Oman
(
Society of Chemical Industry and John Wiley & Sons, Ltd
, 2015 , Article)
Worldwide, many countries are being affected by greenhouse gas (GHG) emissions. The Sultanate of Oman is no exception. In Oman, both oil- and natural-gas-related activities have the most important shares of the nation's ...
Advances in Tailoring Resorcinol-Formaldehyde Organic and Carbon Gels
(
WILEY-VCH Verlag
, 2011 , Article)
An overview on the preparation and properties of resorcinol-formaldehyde (RF) organic and carbon gels reveals the fascinating and remarkably flexible properties of RF carbon and organic gels and how these properties are ...
Antenna subset selection at multi-antenna relay with adaptive modulation
(
John Wiley & Sons, Ltd.
, 2013 , Article)
In this paper, we proposed several antenna selection schemes for cooperative diversity systems with adaptive transmission. The proposed schemes were based on dual-hop relaying where a relay with multiple-antenna capabilities ...
High gain observer for a three-cell chopper: Design and experimental results
(
John Wiley & Sons, Ltd.
, 2014 , Article)
As capacitor voltages are necessary for the three-cell DC�DC chopper control, the estimation of such voltages by an observer is attractive solution in terms of cost. However, due to the hybrid behavior of this structure, ...
Self-Imaging based Dispersion Compensation: Performance and Tolerance of the System
(
IEEE
, 2007 , Article)
Transmitting ultra wideband (UWB) pulse signals over optical fiber is a certain sign of chromatic dispersion (CD) existence. CD is a serious problem in optical transmission because the velocity of light depends on the ...
