Bandwidth Improvement in Bow-Tie Microstrip Antennas: The Effect of Substrate Type and Design Dimensions
(Mdpi, 2020)
In this work, the impact of substrate type and design dimensions on bow-tie microstrip antenna performance and bandwidth improvement is presented both numerically and experimentally at 4-8 GHz. The finite integration ...
An investigation on optimum grinding system and conditions for steel plant ARP by-product α-Fe2O3 for pigment industry
(Elsevier, 2020)
After some other processes, α-Fe2O3 red powder particles -by-product of regeneration of spent pickling liquor in ARP in iron and steel industry- should be ground up to pigment grade to convert it to a value added product, ...
Enhancement of image quality by using metamaterial inspired energy harvester
(Elsevier, 2020)
Metamaterial energy harvester based subwavelength imaging structure is presented. Besides, 2x2 array patch antenna is designed to create incident radiated signal towards the proposed harvester structure. Harvested energy ...
Mutual Coupling Reduction of Cross-Dipole Antenna for Base Stations by Using a Neural Network Approach
(Mdpi, 2020)
In this manuscript, a resonator layer is presented for the purpose of reducing the mutual coupling effect between each antenna element of a cross dipole antenna. In design processes, an artificial neural network approach ...
A theoretical performance investigation of irreversible internal combustion engine named as Dual-Miller Cycle
(Yildiz Technical Univ, 2020)
Internal combustion engines (ICEs) have harmful effects on the environment in terms of emissions. According to present emission regulations, reducing NOx emissions came into prominence. One of the techniques of reducing ...
Design of a Broadband Coplanar Waveguide-Fed Antenna Incorporating Organic Solar Cells with 100% Insolation for Ku Band Satellite Communication
(Mdpi, 2020)
A broadband coplanar waveguide (CPW)-fed monopole antenna based on conventional CPW-fed integration with an organic solar cell (OSC) of 100% insolation is suggested for Ku band satellite communication. The proposed ...
Iron oxide-Si nanoparticle magnetic core-shell induced by the interaction of d-orbitals of Fe2+ with reconstructed Si dimer-like defects
(American Institute of Physics Inc., 2020)
Redox-type charge exchange between Si nanoparticles and aqueous metal ions m(x+) was recently used to synthesize core-shell nanocomposites in which their functionalities have been integrated. The process requires the ...
Electricity production by wet type top-pressure recovery turbine in blast furnaces
(Pamukkale Üniversitesi, 2020)
Today, the iron and steel industry is critical to energy consumption. The high energy demand of the iron and steel production process brings along high costs. This leads to the need to reduce energy demand and develop ...
The effects of interface and matrix reinforcements on fracture toughness of E-Glass/epoxy laminate
(Institute of Physics Publishing, 2020)
In this study, the effects of low amount (0.1 wt%) multi-walled carbon nanotube (MWCNTs) distributed homogenously in epoxy via cationic surfactant (cetyl pyridiniumchloride-CPC), polyacrylonitrile nanofiber (in the range ...
