Multifunctional Oil Absorption with Macroporous Polystyrene Fibers Incorporating Silver-Doped ZnO
(
American Chemical Society
, 2021 , Article)
Hydrophobic microporous polystyrene (PS) fibers are fabricated by a solvent-induced phase-separation-assisted electrospinning method. Zinc oxide (ZnO) and silver-doped zinc oxide (Ag-ZnO) nanomaterials with variable ...
The Effect of the Milling Vial Shape on the In-Situ Consolidation of a Nanocrystalline Al-Li-GNPs Nanocomposite Synthesized by Room Temperature Ball-Milling
(
Frontiers Media
, 2022 , Article)
Several studies investigating the ball-milling of ductile face-centered cubic metals have reported a so-called in-situ consolidation phenomenon where the milled powder is also consolidated during the milling process. Thus, ...
Field-Oriented Control of Five-Phase Induction Motor fed from Space Vector Modulated Matrix Converter
(
Institute of Electrical and Electronics Engineers Inc.
, 2022 , Article)
This paper presents the field-oriented control (FOC) of a five-phase induction motor (FPIM) fed from a three-to-five phase direct matrix converter (DMC). The article focuses on the modulation and control of the three-to-five ...
Assessing Intra-Arab Trade Integration and Potential: Evidence from the Stochastic Frontier Gravity Model
(
International Trade Institute
, 2022 , Article)
This study aims to detect the presence of “behind the border” and “beyond the border” constraints on trade flows among Arab countries, using the stochastic frontier gravity model (SFGM) over the period of 1998 to 2015. The ...
AN EXPERIMENTAL AND NUMERICAL INVESTIGATION OF THE COMBINATION OF DIFFERENT DAMPER TYPES FOR IMPROVED CONTROL OF VIBRATION
(2022 , Master Thesis)
Eliminating and reducing unwanted vibrations required a good knowledge of the dynamic systems fundamental components; mass, spring, and damper. Meanwhile, dampers are responsible for reducing the vibrations amplitudes and ...
