Intrusion detection system for imbalance ratio class using weighted XGBoost classifier
The rapid development of the internet of things (IoT) has taken an important
role in daily activities. As it develops, IoT is very vulnerable to attacks and
creates IoT for users. Intrusion detection system (IDS) can work efficiently
and look for…

Reagentless iron detection in water based on unclad fiber optical sensor
A simple and low-cost fiber based optical sensor for iron detection is
demonstrated in this paper. The sensor head consist of an unclad optical
fiber with the unclad length of 1 cm and it has a straight structure. Results
obtained shows a linear…

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…

ResNet-n/DR: Automated diagnosis of diabetic retinopathy using a residual neural network
Diabetic retinopathy (DR) is a progressive eye disease associated with
diabetes, resulting in blindness or blurred vision. The risk of vision loss was
dramatically decreased with early diagnosis and treatment. Doctors diagnose
DR by examining the…

Wavelet-based sensing technique in cognitive radio network
Cognitive radio is a smart radio that can change its transmitter parameter
based on interaction with the environment in which it operates. The demand
for frequency spectrum is growing due to a big data issue as many Internet
of Things (IoT)…
