Area spectral efficiency of cooperative network with DF and AF relaying
( IEEE , 2012 , Conference Paper)Most performance metrics for cooperative networks focus on the qualification of either spectrum efficiency or link reliability, without considering the spatial effect of radio transmission. Area spectral efficiency (ASE) ... -
Area spectral efficiency of cooperative network with opportunistic relaying
( IEEE , 2012 , Conference Paper)In this paper, we investigate the area spectral efficiency (ASE) in a three-node cooperative network with opportunistic relaying. On one hand, in conventional cellular network, ASE is defined to be the average data rate ... -
Area spectral efficiency of infrastructure relay enhanced cellular systems
( Institution of Engineering and Technology , 2016 , Article)In this study, the authors investigate the downlink area spectral efficiency (ASE) of infrastructure relay enhanced cellular systems. ASE for cellular systems is defined as the maximum achievable data rate per unit bandwidth ... -
Area spectral efficiency of underlay cognitive radio transmission over rayleigh fading channels
( IEEE , 2013 , Conference Paper)Cognitive radio is a promising technology to improve the spectrum utilization by allowing the unlicensed (secondary) user share a frequency bandwidth with the licensed (primary) owner under the condition that no harmful ... -
Area-Specific Traffic Peak Hour Timing Using Traffic Signal Detectors: A Case Study of Qatar
( Qatar University Press , 2023 , Conference Paper)This case study addresses peak hour traffic timing in Qatar after COVID-19 as traffic conditions returned to normal. Traffic data were provided for multiple areas, mainly around Doha City. Flow data were obtained from ... -
Areadynamic analysis of GMC sierra pickup truck
( Institute of Electrical and Electronics Engineers Inc. , 2021 , Conference Paper)Computational Fluid Dynamics (CFD) was used to simulate the flow field over a GMC sierra pickup truck double cab (manufactured year of 2005).

AROMA: A recursive deep learning model for opinion mining in Arabic as a low resource language
( Association for Computing Machinery , 2017 , Article Review)While research on English opinion mining has already achieved significant progress and success, work on Arabic opinion mining is still lagging. This is mainly due to the relative recency of research efforts in developing ... -
Arrester-less DC fault current limiter based on pre-charged external capacitors for half-bridge modular multilevel converters
( Institution of Engineering and Technology , 2017 , Article)The half-bridge modular multilevel converter (HB-MMC) is one of the most promising topologies for high-voltage direct current (HVDC) systems. Unlike full-bridge MMC (FB-MMC) and clamp double sub-module MMC (CDSM-MMC), ... -
Arrhythmia classification using DWT-coefficient energy ratios
( Institute of Electrical and Electronics Engineers Inc. , 2019 , Conference Paper)Certain features present in electrocardiogram (ECG) signals are used to detect different heart conditions.
