Gain Enhancement of a Traditional Horn Antenna using 3D Printed Square-Shaped Multi-layer Dielectric Lens for X-band Applications
(Applied Computational Electromagnetics Society Journal, 2021)
In this work, gain of a traditional horn antenna is enhanced up to 2.9 dB over X-band using 3D printed square-shaped multi-layer lens. For this purpose, firstly the multi-layer lenses are designed using Invasive Weed ...
Pressure leaching of chalcopyrite with oxalic acid and hydrogen peroxide
(Elsevier, 2021)
This study investigated the dissolution behavior of metals from chalcopyrite concentrate in a pressure reactor system in the presence of hydrogen peroxide by oxalic acid leaching. The fact that the compounds formed by ...
Dissolution of Chalcopyrite in Presence of Chelating Agent and Hydrogen Peroxide
(Springer, 2021)
Chelating agents (e.g., EDTA, titriplex III, etc.) are very important salts as they can take a complex form with metal ions. This study investigated usage of titriplex III in presence of hydrogen peroxide for metal extraction ...
Effect of the surface temperature of surface materials on thermal comfort: a case study of Iskenderun (Hatay, Turkey)
(Springer, 2021)
As a result of urbanization that started with the industrial revolution, high temperatures caused by surface materials in built areas cause the formation of urban heat islands. This situation adversely affects the livability ...
Microstrip leaky wave antenna for wide range of beam scanning in X band
(Wiley, 2021)
In this work, design of a pattern reconfigurable antenna is presented for X-band applications as a leaky wave antenna (LWA) realization. Due to the advantages of simple design schematic, low profile, and easy impedance ...
Modelling of the gas-turbine colorless distributed combustion: An application to hydrogen enriched – kerosene fuel
(Elsevier, 2021)
This study examines hydrogen-enriched kerosene combustion under distributed regime in a gas turbine combustion chamber. With hydrogen enrichment, it is aimed at increasing combustion performance of those fuels. However, ...
Impact of the Technological Transformation in Employment and Export on Economic Growth in Turkey and the EU Countries in an Information Economy Projection: Dynamic Panel Data Analysis
(Anemon Muş Alparslan Üniversitesi Sosyal Bilimler Dergisi, 2021)
The technological transformation experienced during the transition to the knowledge economy has
made it necessary to increase the employment of R&D personnel and the export of high-tech
products for countries that want ...
Numerical study of a swirl gas turbine combustor for turbulent air and oxy-combustion of ammonia/kerosene fuels
(Elsevier, 2021)
Since ammonia has a carbon-free substance and involves hydrogen atoms per volume unit, many scientists think it could be used as an alternative fuel instead of natural gas or kerosene-based fuels in gas turbine combustors. ...
Numerical Investigation of Effects of Airspeed and Rotational Speed on Quadrotor UAV Propeller Thrust Coefficient
(Journal of aviation (Online), 2021)
In this article, a numerical investigation was performed on a quadrotor unmanned aeroial vehicles (UAV) propeller to
examine the effects of airspeed and rotational speed on thrust coefficient, which is one of the most ...
Analyze Performance of Embedded Systems with Machine Learning Algorithms
(Springer, 2021)
This article aims to analyze the performance of embedded systems using various machine learning algorithms on embedded systems. For this, data set were analyzed using Python programming language and related libraries. Using ...
