Frequency-dependent electrical parameters and extracted voltage-dependent surface states in Al/DLC/p-Si structure using the conductance method
(Springer, 2023)
In the present work, a diamond-like carbon film (DLC) was electrodeposited on a p-Si substrate and was used to fabricate an Al/DLC/p-Si/Au metal/interlayer/semiconductor (MIS) Schottky diodes (SDs). The structural analysis ...
A monostatic RCS reduction study for an antenna in structural mode at X band
(Taylor and Francis, 2023)
In this paper, a radar cross-section (RCS) reduction of a microstrip antenna is investigated both experimentally and numerically. A traditional metal ground plane antenna and a bandstop frequency selective surface (FSS) ...
Risk mitigation in service industries: A research agenda on container shipping
(Elsevier, 2023)
Shipping lines face various marketing risks, with outcomes that need to be mitigated. A current, serious, example of this has been the COVID19 pandemic and the severe supply chain disruptions that followed it. During such ...
The aerodynamic force estimation of a swept-wing UAV using ANFIS based on metaheuristic algorithms
(Cambridge University Press, 2023)
In this paper, a new approach to modeling and controlling the problems associated with a morphing unmanned aerial vehicle (UAV) is proposed. Within the scope of the study, a dataset was created by obtaining a wide range ...
