(
IEEE
, 2012 , Conference Paper)
Internet-enabled Mobile devices are increasingly used for enhancing the learning experience particularly for language learning. They can be exploited to allow learners to access and interact with multimedia learning resources ...
Evaluation of the modified S-transform for timefrequency synchrony analysis and source localisation
(2012 , Article)
This article considers the problem of phase synchrony and coherence analysis using a modified version of the S-transform, referred to here as the Modified S-transform (MST). This is a novel and important time-frequency ...
Modelling and compensation of frequency-dependent I/Q imbalance in multiple beamforming OFDM transceivers
(
IEEE
, 2012 , Conference Paper)
In this paper, we investigate the effects of asymmetric frequency-dependent joint transmit-receive I/Q imbalance on the performance of multiple beamforming MIMO OFDM systems. We derive the throughput-maximizing TX/RX ...
Performance evaluation of multi-component instantaneous frequency estimation techniques for heart rate variability analysis
(2012 , Conference Paper)
Accurate instantaneous frequency (IF) estimation of the non-stationary heart rate signal is important in quantifying the heart rate variability (HRV) measures. This study compares the effectiveness of four IF estimation ...
Air quality monitoring and prediction system using machine-to-machine platform
(2012 , Conference Paper)
This paper presents an ambient air quality monitoring and prediction system. The system consists of several distributed monitoring stations that communicate wirelessly to a backend server using machine-to-machine communication ...

, 2012 , Article)
In arid and hyper arid regions like Qatar, the time and duration of irrigation is key to achieving sustainable irrigations. This paper proposes a practical solution based on artificial intelligence where all design and ...
Performance analysis of relay selection schemes in underlay cognitive networks with Decode and Forward relaying
(
IEEE
, 2012 , Conference Paper)
In underlay cognitive networks with regenerative relaying, secondary users operating with primary user are adhering to stringent interference constraint which limits their transmission power and coverage area. In order not ...
