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 ...
Classification of Surfaces of Coordinate Finite Type in the Lorentz–Minkowski 3-Space
(MDPI, 2022)
In this paper, we define surfaces of revolution without parabolic points in three-dimensional Lorentz–Minkowski space. Then, we classify this class of surfaces under the condition ∆I I I x = Ax, where ∆I I I is the Laplace ...
Analysis of Factors Affecting the Sustainable Success of Airlines During the COVID-19 Pandemic
(SAGE Publications, 2022)
The COVID-19 pandemic increased the risk of financial distress, bankruptcy, or both, in the airline industry. Whether airlines can survive or not during and/or after the pandemic is closely related to their decisions and ...
Dynamic models for air-breathing and conventional polymer electrolyte fuel cells: A comparative study
(Elsevier, 2022)
Two dynamic models have been built for air-breathing and conventional polymer electrolyte fuel cells (PEFCs) in order to comparatively investigate the impacts of some key parameters on the transient response to load ...
Diverse Properties and Approximate Roots for a Novel Kinds of the (p, q)-Cosine and (p, q)-Sine Geometric Polynomials
(MDPI, 2022)
Utilizing (p, q)-numbers and (p, q)-concepts, in 2016, Duran et al. considered (p, q)-Genocchi numbers and polynomials, (p, q)-Bernoulli numbers and polynomials and (p, q)-Euler polynomials and numbers and provided ...
The Theoretical Value for the Tip Radius of Cracks and Notches
(Kauno Technologijos Universitetas, 2022)
In this paper, an additional equation that can be used in conjunction with the Stress Intensity Factor is produced, enabling the determination of all critical fracture stresses, including tensile strength, from only one ...
A vanadium dioxide-based metamaterial with quatrefoil and circle loaded structure on flexible polyamide substrate for terahertz applications
(Frontiers Media S.A., 2022)
In this study, a novel broadband metamaterial (MTM) absorber is proposed, which is based on vanadium dioxide (VO2) resonators coated onto a flexible polyamide substrate. The VO2 resonator is in the form of a quatrefoil and ...
Phishing Detection System Using Extreme Learning Machines with Different Activation Function based on Majority Voting
(Gazi Üniversitesi, 2022)
Phishing is a type of software-based cyber-attack carried out to steal private information such as login credentials, user passwords, and credit card information. When the security reports published in recent years are ...
Low-Cost Antenna-Array-Based Metamaterials for Non-Invasive Early-Stage Breast Tumor Detection in the Human Body
(MDPI, 2022)
Microstrip patch antennas have been used in many applications since their appearance. Despite their great promise, their narrow bandwidth and the loss at high-frequency bands have limited their usage in medical applications. ...
