Distributed spectrum sensing of correlated observations in cognitive radio networks
(2013 , Conference Paper)
In this paper, Collaborative Spectrum Sensing (CSS) as one of the most efficient sensing approaches in Cognitive Radio Networks (CRNs) is investigated when the Secondary Users (SUs) observations are assumed to be correlated. ...
From global to local: Investigation of necessary engineering skills for KBE transformation in Qatar in the context of global engineering attributes
(
IEEE
, 2013 , Conference Paper)
this paper provides the findings of a study on investigating the required contextual engineering skills in Qatar in light of the global engineering skills. A set of 20 attributes were identified in the literature, and ...
A survey on communication infrastructure for micro-grids
(2013 , Conference Paper)
A micro-grid is a small scale power supply network that is designed to provide electricity to a small community with its own renewable energy sources. Due to distributed generation variability, security and load sharing ...
Finite element modelling of shear strengthened reinforced concrete beams
(
International Institute for FRP in Construction (IIFC)
, 2013 , Conference Paper)
This research aims at creating precise finite element models for FRP shear strengthened concrete beams. It is inspired by the fact that the determination of the structural behaviour of the shear strengthened beams requires ...
On the statistical distribution of electric field inside jet engines
(2013 , Conference Paper)
Using full wave analysis in 'Ansys HFSS', we obtain the electric field distribution inside a jet engine containing one set of 24 blades due to the excitation provided by a simple Hertzian dipole. Hertzian dipole illuminates ...
Impact of location heterogeneity on random walk mobility models
(
Institute of Electrical and Electronics Engineers Inc.
, 2013 , Conference Paper)
This paper investigates random walk mobility models with location heterogeneity, where different locations may have different neighboring regions.With the assumption of totally n locations, we consider two cases, i.e., ...
Transmit and receive cooperative cognition: Protocol design and stability analysis
(
IEEE Computer Society
, 2013 , Conference Paper)
In this paper, we investigate the stability of a cooperative cognitive system. We propose a cooperative secondary transmitter-receiver system (CSTR), where, the secondary transmitter (ST) and the secondary receiver (SR) ...
A robust method for line and word segmentation in handwritten text
(
Hamad bin Khalifa University Press (HBKU Press)
, 2013 , Conference Paper)
Line and word segmentation is a key-step in any document image analysis system. It can be used for instance in handwriting recognition when separating words before their recognition. Line segmentation can also serve as a ...
Multiple-model based sensor fault diagnosis using hybrid kalman filter approach for nonlinear gas turbine engines
(
2013 1st American Control Conference, ACC 2013
, 2013 , Conference Paper)
In this paper, an efficient sensor fault detection and isolation (FDI) strategy is proposed based on multiple-model (MM) approach. The scheme is composed of hybrid kalman filters (HKF) by integrating a nonlinear gas turbine ...
A new five-phase to three-phase back-to-back current source converter based wind energy conversion system
(
IEEE
, 2013 , Conference Paper)
Wind energy is one of the fastest growing renewable energy sources. The increased penetration of wind power into the utility grid brings challenges such as voltage and frequency fluctuations, generator torque ripples, and ...
