A near-optimal LLR based cooperative spectrum sensing scheme for CRAHNs
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Article)
In Cognitive Radio Ad Hoc Networks (CRAHNs), cooperative spectrum sensing schemes exploit spatial diversity of the Secondary Users (SUs), to reliably detect an unoccupied licensed spectrum. Soft energy combining schemes ...
A novel desulfurization practice based on diesel acidification prior to activated carbon adsorption
(
Springer New York LLC
, 2015 , Article)
Commercial diesel is often rich with organosulfur compounds and a value of 7,100 mgS/kg was recently reported. As confirmed by chromatographic analysis, about 36% of sulfur compounds are originated from dibenzothiophene. ...
Multi-component instantaneous frequency estimation using locally adaptive directional time frequency distributions
(
John Wiley & Sons, Ltd.
, 2015 , Article)
This paper presents a locally adaptive time-frequency (t,f) method for estimating the instantaneous frequency (IF) of multi-component signals. A high-resolution adaptive directional time-frequency distribution (ADTFD) is ...
Bioavailability and hypolipidemic effects of peanut skin polyphenols
(
Mary Ann Liebert, Inc.
, 2015 , Article)
Peanut skin is a rich source of polyphenols, such as proanthocyanidins. Peanut skin proanthocyanidins mainly
consist of a subgroup called procyanidins. Peanut-based procyanidins contain oligomers of both type A and type ...
Long-term epileptic EEG classification via 2D mapping and textural features
(
Elsevier Ltd
, 2015 , Article)
Interpretation of long-term Electroencephalography (EEG) records is a tiresome task for clinicians. This paper presents an efficient, low cost and novel approach for patient-specific classification of long-term epileptic ...

(
Emerald Group Publishing Ltd.
, 2015 , Article)
Purpose - The purpose of this paper is to identify and develop a hierarchical model for the barriers affecting the growth of mobile commerce (M-commerce). Based on the model developed, the authors' objective is to identify ...
A fouling suppression system in submerged membrane bioreactors using dielectrophoretic forces
(
Elsevier
, 2015 , Article)
A novel method was developed to suppress membrane fouling in submerged membrane bioreactors. The method is based on the dielectrophoretic (DEP) motion of particles in an inhomogeneous electrical field. Using a real sample ...
Morphology and thermal degradation studies of melt-mixed PLA/PHBV biodegradable polymer blend nanocomposites with TiO2 as filler.
(
Wiley
, 2015 , Article)
The morphology and thermal stability of melt-mixed poly(lactic acid) (PLA)/poly(hydroxybutyrate-co-valerate) (PHBV) blends and nanocomposites with small amounts of TiO2 nanoparticles were investigated. PLA/PHBV at 50/50 ...
A unified approach for calculating the outage performance of two-way af relaying over fading channels
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Article)
Amplify-and-forward-based two-way relaying (TWR-AF) promises significant benefits in wireless networks. In this paper, we aim to obtain unified expressions to determine the outage probability of TWR-AF, regardless of ...
