Nonstationary

AutoSmooth is a compiled stand-alone graphical interface for signal and derivative extraction from time series with nonstationary noise structure. AutoSmooth is now part of the Signal Extraction Toolbox (SET). Platforms: Windows, Mac, Linux

The function plot_hht is a realization of the Hilbert-Huang transform (HHT). The HHT decomposes a signal into intrinsic mode functions (or IMFs), and obtain the instantaneous frequency data. It is designed to work well for data that are nonstationary and nonlinear... Platforms: Matlab

Image compression using wavelet transform *wavelet transform give better information about non-stationary signals in time domain Platforms: Matlab

the stationary signal f(t)=cos(2*pi*5*t)+ cos(2*pi*10*t)+ cos(2*pi*20*t)+ cos(2*pi*50*t)having frequencies of 5,10, 20and 50 Hz at any given time instant.MATLAB program can be implemented to plot the stationary signal mentioned above:Clear... Platforms: Matlab

SSRLSWAM is a combination of SSRLS and stochastic gradient method .It exploits the concept of forgetting factor d?T¬ that may be required due to model uncertainty, presence of unknown external disturbances, time-varying nature of observed signal or Non-stationary behaviour of observation noise. Platforms: Matlab

Simulating the non-stationary progress of the temperature in a Plate.Parameters are Temperature and Heattransfer on each site of the plate and its Dimensions.(Material-parameters of Aluminium were used) Platforms: Matlab
