Microstructure and mechanical properties of friction-stir welded St52 steel joints
(Springer, 2018)
The aim of this work is to investigate the mechanical properties and microstructures of friction-stir welded (FSWed) St52 structural steel joints. In this study, St52 steel plates with a thickness of 4 mm were butt-welded ...
Development of GPS and GIS-Based Monitoring System for the Quality of Excavated Coal
(Technical University of Kosice, faculty Berg, 2018)
Because of the advancement of geospatial technologies such as GIS and GPS integration, many mining companies have started to use the technology for mine planning, analysis and management. In this context, this study focuses ...
Identifying the bond and abrasion behavior of alkali activated concretes by central composite design method
(Elsevier, 2017)
In this paper, bond strength and abrasion resistance of alkali activated concretes (AAC) were examined experimentally by using the central composite design (CCD) method. AAC were designed and produced considering the sodium ...
Performance of two low-cost GPS receivers for ground speed measurement under varying speed conditions
(Springer, 2017)
A global positioning system (GPS) receiver is an important sensor used in modern farming, particularly in precision agriculture to determine geographic location and ground speed. The aim of this study was to investigate ...
Biogenic (β-fabric) features in the hard laminated crusts of the Mersin and Adana regions, southern Turkey and the role of soil organisms in the formation of the calcrete profiles
(Elsevier Science, 2018)
This paper describes beta-fabric features and their distribution in the calcretes, and emphasizes the role of soil organisms in the formation of the calcrete profiles. Quaternary calcretes are common in the Mersin and Adana ...
Electromagnetic Scattering Properties of MWCNTs/Graphene Doped Epoxy Layered with PVC Nanofiber/E-Glass Composites
(Springer, 2020)
In this study, composites composed of glass fiber reinforced-epoxy laminates interleaved with electrospun polyvinylchloride (PVC) nano-fibres were designed for radar absorption investigations. The laminated composites which ...
A Split Meander Line Resonator-Based Permittivity and Thickness Sensor Design for Dielectric Materials with Flat Surface
(Springer, 2018)
A metamaterial-based permittivity and thickness sensor structure for dielectric substrate material has been proposed at the X band frequency regime. The sensor structure is designed by using a split meander line type ...
Prediction of footing settlements with geogrid reinforcement and eccentricity
(ICE Publishing, 2019)
This study presents settlement predictions for footings with geogrid reinforcement and biaxial eccentricity using multi-linear regression (MLR) and artificial neural network (ANN) methods. The effects of central, uniaxial ...
Electromagnetic simulations of polarization-insensitive and wide-angle multiband metamaterial absorber by incorporating double asterisk resonator
(Indian Acad Sciences, 2020)
A novel multiband metamaterial absorber (MTMA) is proposed which is capable of well presenting a polarization-insensitive and wide incident angle stability in the microwave frequency range. The proposed MTMA comprising two ...
A theoretical performance investigation of irreversible internal combustion engine named as Dual-Miller Cycle
(Yildiz Technical Univ, 2020)
Internal combustion engines (ICEs) have harmful effects on the environment in terms of emissions. According to present emission regulations, reducing NOx emissions came into prominence. One of the techniques of reducing ...
