Time-frequency signal and image processing of non-stationary signals with application to the classification of newborn EEG abnormalities
(
IEEE
, 2011 , Conference Paper)
This paper presents an introduction to time-frequency (T-F) methods in signal processing, and a novel approach for EEG abnormalities detection and classification based on a combination of signal related features and image ...
Analysis of the time-varying cortical neural connectivity in the newborn EEG: A time-frequency approach
(
IEEE
, 2011 , Conference Paper)
Relationships between cortical neural recordings as a representation of functional connectivity between cortical brain regions were quantified using different time-frequency criteria. Among these, Partial Directed Coherence ...

, 2011 , Article)
This paper considers the linkage between stock prices and exchange rates in four MENA (Middle East and North Africa) emerging markets. In contrast to the existing evidence that uses a global market index to uncover such a ...
Iterative blocking artefact reduction based on local contrast information
(
IEEE
, 2011 , Conference Paper)
Block based transform coding is the most popular
technique for image and video compression. However, images
compressed using block based algorithms exhibit highly visible
blocking artifacts. We propose an iterative ...

Effect of hyperlipidemia on ketoconazole-midazolam drug-drug interaction in rat
(
John Wiley & Sons, Ltd.
, 2011 , Article)
Hyperlipidemia (HL) was previously shown to lower liver uptake of the more potent (-) enantiomer of ketoconazole (KTZ) in rat. The current study examined the possible modifying influence of experimental HL on a KTZ ...
A radon wigner ville based image dissimilarity measure
(
IEEE
, 2011 , Conference Paper)
In this paper, we introduce a radon wigner ville based image dissimilarity measure. The proposed Image distortion measure aims to combine the useful properties of the wigner ville and the directionality of the finite Radon ...

(
Qatar University
, 2011 , Article)
The study of migration is the key importance not only in Demography but also in Population Studies. Migration is the primary stage of development. Migration is related to development, urbanization, industrialization as ...
Noisy zones of proximal development: Conversation in noisy classrooms
(
Blackwell Publishing Ltd
, 2011 , Article)
Despite the importance of context in studies of language use, sociolinguists have ignored the impact of noise on conversational interaction. This inattention is of particular concern in classrooms where language is a ...
