This study focused on fuel cell electric unmanned aerial vehicle (FC-EUAV) in order to find solutions to problems such as the short-lived and limited long flight endurance of unmanned aerial vehicles operating with fossil ...

Interaction between water and lubrication grease oil is not desirable, but it is not inevitable. The operational life of the machine component is influenced by humid grease oil. Metameterial-based transmission line sensor ...

The exergoeconomic analysis of an urban area is introduced in this study, performed in an annual energy interaction basis. The investigated period covers the year of 2016, and indoor and outdoor temperatures, construction ...

Thanks to the studies on the material properties of the future solar tower systems and together with the developments in the material science, it has been observed that higher operating temperatures can be possible for SPT ...

In this paper, a new system concept is presented for the grid connection of fuel cells. In conventional grid-connected systems, fuel cells ensure the generated power into a single electrical feeder and control the ...

Two novel thiadiazoloquinoxaline and benzodithiophene (BDT) bearing copolymers were designed and synthesized. Different BDT units (alkoxy and thiophene substituted) were used as donor materials and the effect of alkoxy and ...

In this study, a chiral metamaterial sensor applications are created by placing asymmetrically two meander line front and back side of the substrate layer. Characterization of the dielectric constant, thickness and loss ...

A novel broad-band polarization-independent with wide-angle metamaterial absorber(MA) is investigated and demonstrated for solar energy harvesting applications. The proposed MA is composed of two metal layers which have ...

Renewable energy sources are widely available on Earth; hence they have attracted much interest in both research and practical applications. In the large scale renewable energy system, power quality into the grid, especially ...

In this research, interactional effects of four different fiber types, (steel, glass, synthetic and polypropylene) fly ash replacement ratio with cement, electrical arc furnace slag replacement ratio with natural aggregate ...
