IoT-based weather station with air quality measurement using ESP32 for environmental aerial condition study
This article discusses the design of a weather station device that also functions
to measure the concentration of gases in the air. This real-time telemetry
device based on the internet of things (IoT) uses the ESP32 board to process
measurement…

Detection of brain stroke in the MRI image using FPGA
One of the most important difficulties which doctors face in diagnosing is the
analysis and diagnosis of brain stroke in magnetic resonance imaging (MRI)
images. Brain stroke is the interruption of blood flow to parts of the brain that
causes cell…

A numerical-analytical iterative method for solving an electrical oscillator equation
Self-excited oscillation problem occurring from a triode electrical circuit has
been modelled by van der Pol. Until now, the exact solution to the van der Pol
equation is not available. This paper focuses on finding a new method for
solving the…

Neural network technique with deep structure for improving author homonym and synonym classification in digital libraries
Author name disambiguation (AND), also recognized as name-identification,
has long been seen as a challenging issue in bibliographic data. In other words,
the same author may appear under separate names, synonyms, or distinct
authors may have…

Lung cancer classification based on CT scan image by applying FCM segmentation and neural network technique
The number of people with lung cancer has reached approximately 2.09
million people worldwide. Out of 9.06 million cases of death, 1.76 million
people die due to lung cancer. Lung cancer can be automatically identified
using a computer-aided…

Sensitivity of shortest distance search in the ant colony algorithm with varying normalized distance formulas
The ant colony algorithm is an algorithm adopted from the behavior of ants
which naturally ants are able to find the shortest route on the way from the nest
to places of food sources based on footprints on the track that has been passed.
The ant…

Design and implementation of a secured SDN system based on hybrid encrypted algorithms
Software defined network suggests centralizing network knowledge in one
network portion by separating the routing (control plane) mechanism from the
transmission network packet operation (data plane). The control plane is
composed of one, two or…
