Compressive strength prediction models for cementitious composites with fly ash using machine learning techniques
(Elsevier, 2021)
In this study, it was proposed a novel prediction model to predict compressive strength of mortar samples having different properties. For this purpose, 8 different fly ashes were used in mortar mixture as a replacement ...
Seismic metamaterials for low-frequency mechanical wave attenuation
(Springer, 2021)
In this study, a triangular array of cylindrical holes was shown to function as a local resonator to seismic metamaterials against the vibration generator loading in the geophysics concept. The field test showed that the ...
Radio-wave absorption by aluminum and its dependence on the absorption distance
(Springer, 2021)
The absorption of radio wave is relevant to electromagnetic interference (EMI) shielding and low observability. The effect of the absorption distance much above the calculated skin depth on the absorption of radio wave ...
Enhancing the electromagnetic interference shielding effectiveness of carbon-fiber reinforced cement paste by coating the carbon fiber with nickel
(Elsevier, 2021)
The effectiveness of electromagnetic interference (EMI) shielding is valuable for construction materials and can be enhanced by the addition of carbon fiber to cement. This work reports for the first time that nickel coating ...
Experimental verification of phononic crystal based on square arrays of cylindrical holes against seismic vibrations in full-scale systems: modeling, sensing and signal processing of seismic vibrations
(Springer, 2021)
In this study, phononic crystals reducing the earthquake effects will be determined and prototypes will be constructed which can give the opportunity to reduce the effects of seismic waves. Furthermore, test results will ...
DC electric polarization of cured cement paste being unexpectedly hindered by free water
(Wiley, 2021)
Electric polarization is basic to the dielectric behavior, which is pertinent to the science and applications of cement-based materials. This work reports the dynamics of the DC-current-induced electric polarization/depolarization ...
Radio-wave shielding behavior of steel structures
(Taylor and Francis, 2021)
The shielding of radio wave by steel-containing structures is desirable for electronics protection but undesirable for telecommunication signal reception. This work investigates the shielding behavior of steel structures ...
Farklı Konfigürasyonlarda Çelik Metamalzemeler Kullanarak Sismik Etkilerin Azaltılması
(Türk deprem araştırma dergisi (Online), 2021)
Depremlerin yıkıcı etkilerini azaltmak için yapılan çalışmalar, son zamanlarda üzerinde durulan araştırma
konuları arasındadır. Bu çalışmada, kare, üçgen, sinüs ve daire olmak üzere dört farklı saha dizisinde çelik
met ...
Capacitance-based stress self-sensing effectiveness of a model asphalt without functional component
(Elsevier, 2021)
Capacitance-based self-sensing is shown for the first time on a pitch-based material, which serves as model asphalt. No functional component is involved. Compressive stress (5–1720 Pa) is sensed. The capacitance increases ...
Design of a linear to circular polarization converter integrated into a concrete construction for radome applications
(Cambridge University Press, 2021)
In this paper, we present a linear to circular polarization converter integrated in a concrete structure to eliminate signal transmission problem originated from the concrete buildings in microwave regime. Two polarization ...
