Feature selection for effective health index diagnoses of power transformers
(
Institute of Electrical and Electronics Engineers Inc.
, 2018 , Article)
This letter investigates an approach based on feature selection and classification techniques to reduce assessment complexities of power transformers. This approach decreases the number of features by extracting the most ...
Reducing energy consumption of CO2 desorption in CO2-loaded aqueous amine solution using Al2O3/HZSM-5 bifunctional catalysts
(
Elsevier Ltd
, 2018 , Article)
The aim of this work is to find a potential way for great decrease in CO2 capture energy requirement. Here, for the first time, a series of bifunctional Al2O3/HZSM-5 catalysts (Al-ZSM) were prepared by the combined ...
An improved time–frequency noise reduction method using a psycho-acoustic Mel model
(
Elsevier Inc.
, 2018 , Article)
This paper addresses the problem of noise reduction in non-stationary signals. The paper first describes a human physiology based time?frequency (TF) representation (HPTF) using Mel filterbanks. It is then used to improve ...
Exposure to EGF and 17-estradiol irreversibly affects the proliferation and transformation of MCF7 cells but is not sufficient to promote tumor growth in a xenograft mouse model upon withdrawal of exposure
(
Spandidos Publications
, 2018 , Article)
Epidermal growth factor (EGF) and estrogen are potent regulators of breast tumorigenesis. Their short‑term actions on human breast epithelial cells have been investigated extensively. However, the consequence of a long‑term ...
Dilution of seawater using dewatered construction water in a hybrid forward osmosis system
(
Elsevier Ltd
, 2018 , Article)
In this study, dewatered construction water was used for the first time as the feed solution in a combined pretreatment-forward osmosis process to dilute seawater (i.e. draw solution) for further desalination. It was found ...
Influence of TiO2 nanoparticles on the crystallization behaviour and tensile properties of PLA/TiO2, PCL/TiO2 and PLA/PCL/TiO2 nanocomposites.
(
Springer Verlag
, 2018 , Article)
This paper investigated the influence of TiO2 nanoparticles on the morphologies, as well as crystallization behaviour and kinetics, of neat PLA and PCL, and of these polymers in different PLA/PCL blends. We used transmission ...
Proliposome tablets manufactured using a slurry-driven lipid-enriched powders: Development, characterization and stability evaluation
(
Elsevier B.V.
, 2018 , Article)
Proliposome powders were prepared via a slurry method using sorbitol or D-mannitol as carbohydrate carriers in 1:10 or 1:15 w/w lipid phase to carrier ratios. Soya phosphatidylcholine (SPC) and cholesterol were employed ...
Competence and Electability: Exploring the Limitations on Female Candidates in Qatar
(
Routledge
, 2018 , Article)
Attitudes about women’s expertise can play a role in limiting their access to influential public spaces, including elected government positions. In the Arab Gulf, women remain underrepresented in electoral politics. This ...
Plackett-Burman and Box-Behnken designs as chemometric tools for micro-determination of L-Ornithine
(
Elsevier B.V.
, 2018 , Article)
Plackett-Burman (PB) and Box-Behnken (BB) screening and response surface factorial designs were used to evaluate spectrophotometric and spectrofluorimetric approaches for the determination of l-Ornithine (ORN) as per se ...
A one-step implicit iterative method for two finite families of asymptotically nonexpansive mappings in a hyperbolic space
(
Springer Verlag
, 2018 , Article)
We introduce a one-step implicit iterative method for two finite families of asymptotically nonexpansive mappings in a hyperbolic space and use it to approximate common fixed points of these families. The results presented ...
