Periodic component analysis
WebSingular Spectrum Analysis (SSA) SSA is a nonparametric method. It tries to overcome the problems of finite sample length and noisiness of sampled time series not by fitting an assumed model to the available series, but by using a data-adaptive basis set, instead of the fixed sine and cosine of the BT method. Colebrook (1978) applied a form of ... WebApr 12, 2024 · Aegaeon (S/2008 S 1) is the last satellite discovered by the Cassini spacecraft at the end of the 2000 s. Like the satellites Methone and Anthe, it is involved in mean motion resonance with the mid-sized Mimas. In this work, we give a detailed analysis of the current orbit of Aegaeon identifying the resonant, secular and long-term perturbations due to …

The essential component is the key to ensure the quality of user service. We establish a temporal–spatial model for each component and introduce causal structure learning into the model.
WebNov 11, 2014 · Time series analysis - extract and sustract the periodic components. The spectrum of my data set shows 3 periodic components in the time serie. I would like to substract the periodic components to keep the data without these periodicities. It points out periodic events with the periodicity of (1/144 = daily), (1/72 = 1/2daily), and (1/6 = hourly). WebA case study in electrocardiogram (ECG) demonstrates that periodic component analysis is better than the empirical mode decomposition and adaptive filtering methods. Periodic component analysis as a time domain method can discriminate the signal with frequency aliasing, and recover the ECG waveform feature corrupted.
