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…

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…

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…

Design and simulation an optimal enhanced PI controller for congestion avoidance in TCP/AQM system
In this paper, snake optimization algorithm (SOA) is used to find the optimal
gains of an enhanced controller for controlling congestion problem in
computer networks. M-file and Simulink platform is adopted to evaluate the
response of the active…

Deep learning approach to DDoS attack with imbalanced data at the application layer
A distributed denial of service (DDoS) attack is where one or more computers
attack or target a server computer, by flooding internet traffic to the server.
As a result, the server cannot be accessed by legitimate users. A result of this
attack…

Electroencephalography-based brain-computer interface using neural networks
This study aimed to develop a brain-computer interface that can control an
electric wheelchair using electroencephalography (EEG) signals. First, we used
the Mind Wave Mobile 2 device to capture raw EEG signals from the surface of
the scalp. The…

A novel compact dual-band bandstop filter with enhanced rejection bands
In this paper, we present the design of a new wide dual-band bandstop filter
(DBBSF) using nonuniform transmission lines. The method used to design
this filter is to replace conventional uniform transmission lines with
nonuniform lines governed by…

Design, simulation, and analysis of microstrip patch antenna for wireless applications operating at 3.6 GHz
In this study, a microstrip patch antenna that works at 3.6 GHz was built and
tested to see how well it works. In this work, Rogers RT/Duroid 5880 has been
used as the substrate material, with a dielectric permittivity of 2.2 and a thickness
of…
