Wavelet Transform with Histogram-Based Threshold Estimation for Online Partial Discharge Signal Denoising
( Institute of Electrical and Electronics Engineers Inc. , 2015 , Article)Online condition assessment of the power system devices and apparatus is considered vital for robust operation, where partial discharge (PD) detection is employed as a diagnosis tool. PD measurements, however, are corrupted ... -
Wavelet-based Encoding Scheme for Controlling Size of Compressed ECG Segments in Telecardiology Systems
( Springer New York LLC , 2017 , Article)One of the major issues in time-critical medical applications using wireless technology is the size of the payload packet, which is generally designed to be very small to improve the transmission process. Using small packets ... -
Wavelet-based multiscale filtering of genomic data
( IEEE Computer Society , 2012 , Conference Paper)Measured biological data are a rich source of information about the biological phenomena they represent. For example, time-series genomic or metabolic microarray data can be used to construct dynamic genetic regulatory ... -
A wavelet-based passive islanding detection technique
( IEEE , 2012 , Conference Paper)Distribution power systems are radial in nature. Power flows in one direction from the utility to the load. Most protection, monitoring, and control devices are designed based on this unidirectional flow of power. Distributed ... -
