This work presents a new epileptic seizures epoch classification scheme. Variational mode decomposition (VMD), has been explored for non-recursively decomposing the electroencephalogram (EEG) signals into fourteen band limited intrinsic mode functions (IMFs). Data augmentation (DA), has been used for handling unbalanced classification problem. Normalized energy, fractal dimension, number of peaks,...
This paper deal with the design and implementation of low cost, indigenous 2-axis ultrasonic anemometer having real time SD card and Internet of Things (IOT) enabled data logging. Ultrasonic Anemometer is a measuring instrument which is capable of measuring wind velocity (i.e. both wind speed and direction) in a challenging environment like ladakh where conventional type anemometers are not working...
Periodic noise has a global impact in spatial domain and can only be removed using frequency domain analysis. In this paper, a novel frequency domain technique is proposed for the removal of semi-periodic and quasi-periodic noise for both gray scale images and color images. This method includes auto detection using local thresholding. Weighted Gaussian Notch Filter (WGNF) is used to suppress noisy...
