Metaheuristic optimization in neural network model for seasonal data
The use of metaheuristic optimization techniques in obtaining the optimal
weights of neural network model for the time series was the main part of this
research. The three optimization methods used as experiments were genetic
algorithm (GA),…

An assisting model for the visually challenged to detect bus door accurately
Visually impaired individuals are increasing and as per global statistics,
around 39 million are blind, and 246 million are affected by low vision. Even
in India, as per the recent reviews, over 5 million visually challenged people
are present.…

An effective new iterative CG-method to solve unconstrained non-linear optimization issues
In this paper, we proposed a matrix-free double-search direction based on the
updated parameter file of the double-search direction with a new
mathematical formula for the gamma parameter. When comparing the
numerical results of this algorithm…

Extraction of object image features with gradation contour
Image retrieval using features has been used in previous studies including
shape, color, texture, but these features are lagging. With the selection of
high-level features with contours, this research is done with the hypothesis
that images on…

Power saving MAC protocols in wireless sensor networks: a survey
In a wireless sensor network, energy is almost always the greatest limitation.
Energy sources are restricted in many of the environments where nodes are
deployed, limiting them to the use of batteries for power. Therefore,
conserving energy is…
