Thermal analysis and wear behavior of shell mold cast and graphite mold cast Mg-4Zn-(x)Zr alloys
(CSIC Consejo Superior de Investigaciones Cientificas, 2021)
The grain refining effect of Zirconium (Zr) is known, nevertheless the effect of Zr amount and its effect on solidification and wear behavior of modified Mg-Zn alloys has not been adequately studied. Mg-4Zn-(x)Zr alloys ...
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 ...
Accurate Modeling of Frequency Selective Surfaces Using Fully-Connected Regression Model With Automated Architecture Determination and Parameter Selection Based on Bayesian Optimization
(Institute of Electrical and Electronics Engineers Inc., 2021)
Surrogate modeling has become an important tool in the design of high-frequency structures. Although full-wave electromagnetic (EM) simulation tools provide an accurate account for the circuit characteristics and performance, ...
Electrically Driven VTOL Flying Car Designing and Aerodynamic Analysis
(Avrupa Bilim ve Teknoloji Dergisi, 2021)
In this study, the design of the electric powered VTOL Flying car was made in the CAD program, and the longitudinal, vertical and
lateral flight dynamics were examined and aerodynamic analysis was made. In the design, the ...
Study on the Water Transport System in the Northern Region of Dhaka; the Capital City of Bangladesh
(İskenderun Teknik Üniversitesi, 2022)
All the megacities in the world suffer from traffic jam at certain period of the day but in case of Dhaka with addition of traffic jam it also faces total traffic chaos and mismanagement. In different times, Government of ...
MALE UAV selection in interval Type-2 fuzzy sets environment
(IOS Press BV, 2022)
Unmanned Aerial Vehicles (UAVs) are increasingly used in the military field. Especially in recent years, UAVs have been a very effective instrument in gaining airspace superiority and military success. Many countries compete ...
A Symmetrical Terahertz Triple-Band Metamaterial Absorber Using a Four-Capacitance Loaded Complementary Circular Split Ring Resonator and an Ultra-Thin ZnSe Substrate
(MDPI, 2022)
In this research work, a symmetrical four-capacitance loaded complementary circular split ring resonator is proposed, which uses an ultra-thin Zinc Selenide (ZnSe) substrate to realize a low-profile triple-band metamaterial ...
Air-breathing versus conventional polymer electrolyte fuel cells: A parametric numerical study
(Elsevier, 2022)
Two mathematical models have been built for air-breathing and conventional polymer electrolyte fuel cells to explore the reasons affecting the cell performance. A parametric study has been conducted to (i) investigate how ...
Novel decision-making strategy for working fluid selection in Organic Rankine Cycle: A case study for waste heat recovery of a marine diesel engine
(Elsevier, 2022)
The Organic Rankine Cycle (ORC) is receiving increasing attention as a waste heat recovery system. However, it is still a major challenge to quickly and practically choose the appropriate one among dozens of working fluids, ...
Radiation pattern reconfigurable cubical antenna array for 2.45 GHz wireless communication applications
(Springer, 2022)
In this paper a single-fed four-faced multidirectional compact antenna is introduced for 2.45 GHz indoor wireless applications. Firstly, a slotted patch antenna is designed to operate at 2.45 GHz and its equivalent circuit ...
