WebA power grid harmonic signal is characterized as having both nonlinear and nonstationary features. A novel multifractal detrended fluctuation analysis (MFDFA) algorithm combined with the empirical mode decomposition (EMD) theory and template movement is proposed to overcome some shortcomings in the traditional MFDFA algorithm. The novel algorithm … WebIn this paper, we make use of the empirical mode decomposition (EMD) to discriminate the cervical cancer tissues from normal ones based on elastic scattering spectroscopy. The … Signals often consist of multiple physically meaningful components. Quite often, you want to study one or more of these components in isolation on the same time scale as the original data. Multiresolution analysis refers to breaking up a signal into components, which produce the original signal exactly when … See more Real-world signals are a mixture of different components. Often you are only interested in a subset of these components. Multiresolution analysis allows you to … See more The point of separating signals into components is often to remove certain components or mitigate their effect on the signal. Crucial to MRA techniques is the … See more In the previous examples, the role of multiresolution analysis in the detection of oscillatory components in the data and an overall trend was emphasized. However, … See more In this example, we discussed wavelet and data-adaptive techniques for multiresolution analysis. What are some of the advantages and disadvantages of the … See more the poetical works of robert stephen hawker
