Big data cloud-based recommendation system using NLP techniques with machine and deep learning
Recommendation systems (RS) are crucial for social networking sites.
Without it, finding precise products is harder. However, existing systems
lack adequate efficiency, especially with big data. This paper presents a
prototype cloud-based…

Reflector antenna design in different frequencies using frequency selective surfaces
In this study, it is aimed to obtain two different asymmetric radiation patterns
obtained from antennas in the shape of the cross-section of a parabolic
reflector (fan blade type antennas) and antennas with cosecant-square…

Evaluation of the weighted-overlap add model with massive MIMO in a 5G system
The flaw in 5G orthogonal frequency division multiplexing (OFDM) becomes
apparent in high-speed situations. Because the doppler effect causes frequency
shifts, the orthogonality of OFDM subcarriers is broken, lowering both their
bit error rate…

Impact of CuS counter electrode calcination temperature on quantum dot sensitized solar cell performance
In place of the commercial Pt electrode used in quantum sensitized solar
cells, the low-cost CuS cathode is created using electrophoresis. High
resolution scanning electron microscopy and X-ray diffraction were used to
analyze the structure and…
