Spherical bipolar fuzzy weighted multi-facility location modeling for mobile COVID-19 vaccination clinics
(IOS Press, 2022)
A pandemic was declared in 2020 due to COVID-19. The most important way to deal with the virus is mass vaccination which is a complex task in terms of fast transportation and process management. Hospitals and other health ...
Methane decomposition over Fe-based catalysts
(Elsevier Ltd, 2020)
Catalytic approach for methane decomposition can be seriously considered as a promising process for COx free hydrogen generation. In this study, catalytic methane decomposition was performed using Fe-based catalysts, and ...
Single steel strut mechanical testing: challenges and future research directions
(Taylor & Francis Ltd, 2019)
Open-cell stainless steel foams, composed of hollow struts, are excellent candidates for energy absorption and thermo-mechanical applications. The basic mechanical element responsible for the function of these foams is the ...
Effect of surface modification of colloidal silica nanoparticles on the rigid amorphous fraction and mechanical properties of amorphous polyurethane-urea-silica nanocomposites
(Wiley, 2019)
Colloidal silica nanoparticles (NPs) modified with eight different silane coupling agents were incorporated into an amorphous poly(tetramethylene oxide)-based polyurethane-urea copolymer matrix at a concentration of 10 wt ...
Techno-economic analysis of PV systems with manually adjustable tilt mechanisms
(Elsevier, 2022)
Solar radiation falling on photovoltaic (PV) panel surface can be maximized via solar tracking systems, however, in return for infeasible investments. On the other hand, manual and periodic tilt adjustment of PVs can ...
An experimental study on the heat transfer and wettability characteristics of micro-structured surfaces during water vapor condensation under different pressure conditions
(Elsevier Ltd, 2021)

Performance analysis of Hexagonal QAM constellations on quadrature spatial modulation with perfect and imperfect channel estimation
(Elsevier, 2021)
In this study, the quadrature spatial modulation (QSM) technique, which is a rational multiple-input multiple-output (MIMO) transmission technique and frequently encountered in recent studies in the literature, and the ...
Effects of alumina (Al2O3) addition on the cell structure and mechanical properties of 6061 foams
(Cambridge Univ Press, 2013)
In this study, a powder blend representing 6061 Al-alloy was first mixed with Al2O3 ceramic particles and then foamed by using the powder compact melting method. 6061-Al2O3 foams and control specimens 6061 foams (without ...
Application of a pnCCD for energy-dispersive Lauc diffraction with ultra-hard X-rays
(Int Union Crystallography, 2015)
In this work the spectroscopic performance of a pnCCD detector in the ultra-hard energy range between 40 and 140 keV is tested by means of an energy-dispersive Laue diffraction experiment on a GaAs crystal. About 100 Bragg ...
