Modelling the degradation of vibration characteristics of reinforced concrete beams due to flexural damage
(
John Wiley & Sons, Ltd.
, 2015 , Article)
This paper presents an improved crack model incorporating non-linearity of flexural damage in concrete to reproduce changes in vibration properties of cracked reinforced concrete beams. A reinforced concrete beam model ...
To Relay or Not To Relay in Cognitive Radio Sensor Networks
(
IEEE
, 2014 , Article)
A recent investigation on MAC layer in cognitive radio networks proposed the primary packet relaying by the secondary node maintaining an extra queue used for this particular addable functionality. Nevertheless, relaying ...
Exact SINR analysis of OFDM systems under joint Tx/RX I/Q imbalance
(
IEEE
, 2013 , Conference Paper)
The direct-conversion architecture used for Orthogonal Frequency Division Multiplexing (OFDM) systems suffers from intercarrier interference (ICI) between image subcarriers in each OFDM symbol due to I/Q imbalance between ...
Maximizing Energy Efficiency in Multiple Access Channels by Exploiting Packet Dropping and Transmitter Buffering
(
IEEE
, 2015 , Article)
Quality of service (QoS) for a network is characterized in terms of various parameters specifying packet delay and loss tolerance requirements for the application. The unpredictable nature of the wireless channel demands ...
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 ...
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 ...
