Investigation of microwave power limiter for Industrial Scientific Medical band (ISM) applications
(Wiley, 2020)
In this paper, a new design of microstrip power limiter which is based on microstrip technology and zero bias Schottky diode is introduced. In this context, the FR-4 substrate that was characterized by dielectric permittivity ...
Impulsive Modelling of Noise for OFDM Systems in Power Line Communication: A Necessity or a Redundant Task?
(Springer Singapore Pte, 2020)
In Power Line Communication, variations in the characteristics of power lines and additive noise reduce the efficiency of Orthogonal Frequency Division Multiplexing (OFDM), and that makes channel estimation essential. The ...
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 ...
Computation of Robust PI-Based Pitch Controller Parameters for Large Wind Turbines
(IEEE Canada, 2020)
This paper deals with the computation of all proportional-integral (PI)-based pitch controllers which achieve the desired frequency-domain specifications, namely, gain and phase margins (GPMs) of a large wind turbine (LWT) ...
Effect of Different Arc Welding Processes on the Metallurgical and Mechanical Properties of Ramor 500 Armor Steel
(Asme, 2020)
In the present study, Ramor 500 armor steel plates were automatically welded using cold metal transfer arc welding (CMT), gas metal arc welding (GMAW), and hybrid plasma arc welding (HPAW) methods. To investigate the effects ...
Electromagnetic Scattering Properties of MWCNTs/Graphene Doped Epoxy Layered with PVC Nanofiber/E-Glass Composites
(Springer, 2020)
In this study, composites composed of glass fiber reinforced-epoxy laminates interleaved with electrospun polyvinylchloride (PVC) nano-fibres were designed for radar absorption investigations. The laminated composites which ...
Conceptual design analysis for a lightweight aircraft with a fuel cell hybrid propulsion system
(Taylor and Francis Inc., 2020)
With the ever-growing aviation industry, energy researches on aviation have turned to renewable energy sources providing electric propulsion. Fuel cells are one of the most popular sources of power for electric vehicles ...
The Detection of Chemical Materials with a Metamaterial-Based Sensor Incorporating Oval Wing Resonators
(MDPI, 2020)
The detection of branded and unbranded chemical materials is essential for the quality control assessment. In this work, a metamaterial inspired sensor is designed and fabricated, which incorporates oval-shaped wing ...
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 ...
A reflection-only method for characterizing PEC-backed anisotropic materials using waveguide higher order modes
(Wiley, 2020)
This paper presents a new reflection-only set-up for characterizing the properties of an anisotropic PEC-backed materials. Albeit, the reflection-only methods are established long ago, they are not elaborated appropriately ...
