The record of human brain neural activities, namely electroencephalogram (EEG), is generally known as a non-stationary and nonlinear signal. In many applications, it is useful to divide the EEGs into segments within which the signals can be considered stationary. Combination of empirical mode decomposition (EMD) and Hilbert transform, called Hilbert-Huang transform (HHT), is a new and powerful ...

High ground-level ozone (GLO) concentrations will adversely affect human health, vegetations as well the ecosystem. Therefore, continuous monitoring for GLO trends is a good practice to address issues related air quality based on high of GLO. The purpose this study introduce stationary and non-stationary model extreme method applied 25 selected stations in Peninsular Malaysia. maximum daily con...
