On the group proportional fairness of frequency domain resource allocation in L-SC-FDMA based LTE uplink
(
IEEE
, 2010 , Conference Paper)
Localized single carrier frequency division multiple access (L-SC-FDMA) has been selected as the uplink transmission scheme in 3GPP Long Term Evolution (LTE) due to its low Peak to Average Power Ratio (PAPR) over OFDMA in ...
Estimation of highly selective channels for downlink LTE systemby a robust neural network
(
Hamad bin Khalifa University Press (HBKU Press)
, 2010 , Conference Paper)
In this paper we propose a robust channel estimator for the downlink of a Long Term Evolution (LTE) system using a highly selective neural network. This method uses the information provided by the reference signals to ...
Investigation of the Learning Environment in Higher and Lower Performing "Education for a New Era" Schools
(2010 , Conference Paper)
Recently, Qatar established key elements of educational reform including curriculum standards; emphasis on student-centered teaching; charter school establishment; standards-based assessment; English as the language of ...
Real-time traffic surveillance using ZigBee
(
Institute of Electrical and Electronics Engineers Inc.
, 2010 , Conference Paper)
This paper describes the design, implementation, and analysis of a proof-of-concept prototype of a traffic surveillance system. The system employs an in-vehicle device for collecting real-time traffic data. The device uses ...
Blind Deconvolution for retinal image enhancement
(
IEEE
, 2010 , Conference Paper)
In this paper, a new technique is presented to enhance the blurred images obtained from retinal imaging. One of the main steps in inspecting the eye (especially the deeper image of retina) is to look into the eye using a ...
Identifying crack parameters in slow rotating machinery using vibration measurements and hybrid neuro-particle swarm technique
(2010 , Conference Paper)
Low-cycle fatigue-initiated cracks may result in failure in slow-rotating equipments. Online monitoring to identify such fault/crack parameters, namely crack size and crack location, would be critical in providing an early ...
Effect of gamma irradiation on the microstructure and morphology of polyethylene oxide and polyvinyl alcohol blends
(
Trans Tech Publications
, 2010 , Conference Paper)
Thin films of a blend of 90, 75, 50 (wt/wt%) percentage of polyethylene oxide and polyvinyl alcohol were synthesized and irradiated with 5, 25, 50, 100 and 200 kGy. The presence of PVA leads to diffusion controlled mechanism ...
Arabic speech-controlled wheelchair: A Fuzzy scenario
(
IEEE
, 2010 , Conference Paper)
In this paper, the design of a speech-controlled wheelchair is presented. The main motivation for this design came through the feedback from personal experiences of several colleagues as well as rehabilitation centers of ...
Blind restoration of fluorescein angiography images
(
IEEE
, 2010 , Conference Paper)
In this paper, a new technique is presented to enhance the blurred images obtained from Fluorescein Angiography (FA) of the retina. One of the main steps in inspecting the eye (especially the deeper image of retina) is to ...
Conceptual ascendant feature extraction of a financial corpus
(
IEEE
, 2010 , Conference Paper)
In the scope of Financial Watch project, in order to create a feature of a corpus reflecting its semantic structure, a general algorithm of text micro structuring and browsing is proposed. The same conceptual algorithm has ...
