Sentiment analysis has drawn considerable interest among researchers owing to the realization of its fascinating commercial and business benefits. This paper deals with sentiment analysis in Arabic text from three perspectives. ...
Interference-aware energy-efficient cross-layer design for healthcare monitoring applications
(
Elsevier
, 2014 , Article)
Body Area Sensor Networks (BASNs) leverage wireless communication technologies to provide healthcare stakeholders with innovative tools and solutions that can revolutionize healthcare provisioning; BASNs thus promotes new ...
Microstructure evolution and mechanical properties of twinned AZ31 alloy plates at lower elevated temperature
(
Elsevier Ltd
, 2014 , Article)
The AZ31 alloy plates were pre-rolled at room temperature along the transverse direction to introduce extension twinning. The effect of pre-existing twins on the mechanical properties of AZ31 alloy plates at lower elevated ...
Quadrupolar benzobisthiazole-cored arylamines as highly efficient two-photon absorbing fluorophores
(
American Chemical Society
, 2014 , Article)
A computer-aided design of novel D-?-A-?-D styrylamines containing five isomeric benzobisthiazole moieties as the electron-accepting core has revealed the linear centrosymmetric benzo[1,2-d:4,5-d?]bisthiazole as the most ...
Optimization of selection of chain amine scrubbers for CO2 capture
(
Springer Verlag
, 2014 , Article)
In order to optimize the selection of a suitable amine molecule for CO2 scrubbers, a series of ab initio calculations were performed at the B3LYP/6-31+G(d,p) level of theory. Diethylenetriamine was used as a simple chain ...

لقد كنا نسمع إلى وقت قريب أن العالم ينقسم إلى شرق وغرب. وينقسم الشرق إلى: أدنى، وأقصى، وأوسط. وقد توارت في العصر الحديث فكرة التقسيمات تلك على هذا المستوى اللهم إلا لتمييز الموقع فحسب لا سيما بعد أصبح العالم قرية صغيرة ...
An interline dynamic voltage restoring and displacement factor controlling device (IVDFC)
(
IEEE
, 2014 , Article)
An interline dynamic voltage restorer (IDVR) is invariably employed in distribution systems to mitigate voltage sag/swell problems. An IDVR merely consists of several dynamic voltage restorers (DVRs) sharing a common dc ...
Theoretical study on amino acid-based ionic pairs and their interaction with carbon nanostructures
(
American Chemical Society
, 2014 , Article)
Quantum chemistry methods were used to analyze the properties of ionic pairs formed by combination of the 1-ethyl-3-methylimidazolium cation with anions derived from alanine, glycine, serine, and phenylalanine amino acids, ...
Comparative skull analysis suggests species-specific captivity-related malformation in lions (Panthera leo)
(
Public Library of Science
, 2014 , Article)
Lion (Panthera leo) populations have dramatically decreased worldwide with a surviving population estimated at 32,000 across the African savannah. Lions have been kept in captivity for centuries and, although they reproduce ...
Improved mechanical properties of AZ31 magnesium alloy plates by pre-rolling followed by warm compression
(
Elsevier Ltd
, 2014 , Article)
AZ31 magnesium alloy plates were processed by pre-rolling followed by warm compression. The corresponding microstructure evolution and mechanical properties were investigated in the present paper. The pre-introduced twins ...
