On critical point avoidance among mobile terminals in healthcare monitoring applications: Saving lives through reliable communication software
(
IEEE
, 2012 , Conference Paper)
The advances in Microelectromechanical systems (MEMS), battery life, low powered communication standards, more capable processing units, and hybrid communication have cemented the use of mobile Wireless Body Area Networks ...
Horvitz-thompson estimator of population mean under inverse sampling designs
(
Iranian Mathematical Society
, 2012 , Article)
Inverse sampling design is generally considered to be an appropriate technique when the population is divided into two subpopulations, one of which contains only a few units. Here, we de- rive the Horvitz-Thompson estimator ...
Effect of serum lipoproteins on stereoselective halofantrine metabolism by rat hepatocytes
(
John Wiley & Sons, Ltd
, 2012 , Article)
Experimental hyperlipidemia has shown to decrease cytochrome P450 3A4 and 2C11 expression and to increase liver concentrations and the plasma protein binding of halofantrine (HF) enantiomers. The present study examined the ...
Secure service provision in smart grid communications
(2012 , Article)
The smart grid provides a platform for thirdparty service providers to remotely monitor and manage energy usage for consumers. At the same time, the involvement of service providers brings a new set of security threats to ...
Forced spectrum access termination probability analysis under restricted channel handoff
(2012 , Conference Paper)
Most existing works on cognitive radio networks assume that cognitive (or secondary) users are capable of switching/jumping to any available channel, regardless of the frequency gap between the target and the current ...
Improving the classification of newborn EEG time-frequency representations using a combined time-frequency signal and image approach
(2012 , Conference Paper)
This paper presents new time-frequency (T-F) features to improve the classification of non-stationary signals such as EEG signals. Previous methods were based only on signal features that were derived from the instantaneous ...
Generalised phase synchrony within multivariate signals: An emerging concept in time-frequency analysis
(2012 , Conference Paper)
This paper introduces the notion of the instantaneous frequency (IF) based generalized phase synchrony in time-frequency analysis based on the concept of cointegration. This phase synchrony is then quantified by investigating ...
Correlation between synthesis variation of 2-alkylquinolones and the antifungal activity of aBurkholderia cepacia strain collection
(
Springer Netherlands
, 2012 , Article)
Twenty epiphytic and rhizospheric bacterial strains harbouring strong antifungal activities were isolated from the Tunisian environment. This group of bacteria was identified as Burkholderia cepacia genomovar I using 16S ...
Towards understanding the effects of climatic and environmental factors on solar PV performance in arid desert regions (Qatar) for various PV technologies
(
IEEE
, 2012 , Conference Paper)
The sensitivity of various solar photovoltaic technologies to dust, temperature and relative humidity is investigated for Qatar's environment. Results obtained show that mono-crystalline PVs have efficiencies as high as ...
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) ...
