Improved Modeling of Microwave Structures Using Performance-Driven Fully-Connected Regression Surrogate
(Institute of Electrical and Electronics Engineers Inc., 2021)
Fast replacement models (or surrogates) have been widely applied in the recent years to accelerate simulation-driven design procedures in microwave engineering. The fundamental reason is a considerable-and often prohibitive-CPU ...
Microwave absorption performance of hexagonal nano boron nitride doped basalt fabric-reinforced epoxy composites
(Emerald Group Publishing Ltd., 2021)
Purpose: The purpose of this paper is to investigate the effect of doping element on the microwave absorption performance of hexagonal nano boron nitride (h-nBN)-reinforced basalt fabric (BF)/epoxy composites. A new type ...
Wideband Microwave Absorber Comprising Metallic Split-Ring Resonators Surrounded With E-Shaped Fractal Metamaterial
(Institute of Electrical and Electronics Engineers Inc., 2021)
A specially designed metallic E-shaped fractal-based perfect metamaterial absorber (PMA) with fairly wideband absorptivity in the K- and Ka-bands of the microwave regime was investigated. The PMA top surface is comprised ...
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 ...
Free vibration analysis of a rotating single edge cracked axially functionally graded beam for flap-wise and chord-wise modes
(Elsevier, 2021)
This study concerns with the free vibration analyses for centrifugally stiffened cracked beams modelled as functionally graded material in the axial direction. The variation of material properties along the cracked beam ...
A compact triband antipodal Vivaldi antenna with frequency selective surface inspired director for IoT/WLAN applications
(Springer, 2021)
In this paper, an antipodal triband Vivaldi antenna operating in 2.4/5.2/5.8 GHz bands has been presented for WLAN/IoT applications. The proposed antipodal Vivaldi antenna has meander line shaped slotted lines, which are ...
A fuzzy logic-based intelligent decision support system for the selection of an appropriate input-shaping technique for controlling flexible link systems
(Taylor and Francis, 2021)
Most robotic systems consist of heavy machine elements that help reduce the vibrations generated by motion and that support good positional accuracy. Large-sized actuators are needed for such systems. Energy consumption ...
Experimental and Numerical Investigation of 3D Dam-Break Wave Propagation in an Enclosed Domain with Dry and Wet Bottom
(MDPI, 2021)
Dam-break flood waves represent a severe threat to people and properties located in downstream regions. Although dam failure has been among the main subjects investigated in academia, little effort has been made toward ...
Experimental and numerical investigation of new flexible connection elements between infill walls-RC frames
(Elsevier, 2021)
Lateral stiffness provided by infill walls to the building structures is generally neglected in designs. Infill walls, which are only included in the calculations as dead loads, significantly affect the lateral resistance, ...
Investigation of construction material quality and workmanship defects of rc buildings collapsed and severely damaged in the 6.8 MW sivrice, Elaziğ, Turkey, Earthquake, January 2020
(New Zealand Society for Earthquake Engineering, 2021)
In the Sivrice, Elazig, Turkey earthquake on January 24, 2020, 41 people lost their lives, more than 1600 people were injured, 672 buildings collapsed, and around 12600 buildings were severely damaged due to poor construction ...
