Estimation of daily evapotranspiration in Kosice City (Slovakia) using several soft computing techniques
(Springer, 2021)
Accurate estimation of evapotranspiration is one of the main aspects of water management. In this study, the capabilities of soft computing techniques for estimating daily evapotranspiration in Košice (Slovakia) were ...
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 ...
Optimizing the Gain and Directivity of a Microstrip Antenna with Metamaterial Structures by Using Artificial Neural Network Approach
(Springer, 2021)
The purpose of this study is to improve the gain and directivity of the microstrip patch antenna by means of metamaterial (MTM) structures. As it is known, antennas have power densities in a certain direction, and the ...
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 ...
Uniaxial stress-strain relation for low- and normal-strength concrete in compression
(ICE Publishing, 2021)
In the modelling and simulation of reinforced concrete structures, accurate definition of material properties is important in terms of obtaining precise results. Among the parameters defining the behaviour of concrete in ...
Numerical modeling of the dam-break wave impact on elastic sluice gate: A new benchmark case for hydroelasticity problems
(Elsevier, 2021)
This paper presents a newly-designed experimental setup based on the interaction of a dam-break flow with an elastic sluice gate in the context of the hydroelasticity problems. As the experimental measurement, displacements ...
A study on determination of the frost depths for building foundations in the Central Anatolia Region of Turkey
(Springer, 2021)
The building foundations should be designed below frost depth due to the harmful effects of frost-related problems. In this study, the climate and geological properties of the Central Anatolia Region in Turkey were presented, ...
