Abstract X-band operation is improved with the help of the horn antenna, and the exercises carried out in this study use computerised simulation and measurements. The antenna aperture with 60 degrees is fixed to expand the strips by linear expansion. In the strips, the four-quarter wavelength monopole antennas are placed.

X-band operation is improved with the help of the horn antenna, and the exercises carried out in this study use computerised simulation and measurements. The antenna aperture with 60 degrees is fixed to expand the strips by linear expansion. In the strips, the four-quarter wavelength monopole antennas are placed. The strips have an array fabricated with 20 mm and 1 mm thicknesses. The horn arms specification is fixed at 60 mm long, and the aperture angle is 60 degrees. The SMA connector pins are placed at a quarter-length distance from the strip circuits. Read More Read Less

Abstract Fossil fuel removal is an impediment in the current world for which we have many systems and methodologies. Hydrogen-dependent technologies have the potential to do this task. In the applications, there are many issues even if it has potential in applications. We focused the solid-oxide fuel cells as they offer better efficiency and return for electric conversion. During operations, thermal... Fossil fuel removal is an impediment in the current world for which we have many systems and methodologies. Hydrogen-dependent technologies have the potential to do this task. In the applications, there are many issues even if it has potential in applications. We focused the solid-oxide fuel cells as they offer better efficiency and return for electric conversion. During operations, thermal stress and material degradation affect durability. We review the techniques, systems, and new achievements in diagnosis and overall health management. Read More Read Less

Abstract This work predicted the wireless channel environment on extreme learning machines. The environment we have selected has single output systems in microcellular and picocellualar characteristics. The performance indicators include the average squared error and time consumption for operations. In the experimentation process, we found that the signal-to-noise ratio values reflected less execution time and higher accuracy. ...
