Bearing fault detection in a 3 phase induction motor using stator current frequency spectral subtraction with various wavelet decomposition techniques

open access: yesAin Shams Engineering Journal, 2018
Induction motors consumes 90% of total power consumed by industries due to large scale utilisation. Even though these motors are rugged in structure, they often face unexpected failure due to long usage without maintenance.

Wavelet compression for remotely sensed images

open access: yesIraqi Journal of Physics, 2012
Image compression is very important in reducing the costs of data storage transmission in relatively slow channels. Wavelet transform has received significant attention because their multiresolution decomposition that allows efficient image analysis ...

Hybrid Transform Based Denoising with Block Thresholding

open access: yesمجلة كلية التربية للبنات, 2019
A frequently used approach for denoising is the shrinkage of coefficients of the noisy signal representation in a transform domain. This paper proposes an algorithm based on hybrid transform (stationary wavelet transform proceeding by slantlet transform);
