Frequency-Weighted Singular Spectrum Analysis for Time Series

Advances in Data Science and Adaptive Analysis, 2022
Singular spectrum analysis (SSA) is a nonparametric spectral decomposition of a time series. A time series is exactly separated into arbitrary number of additive subsequences with the singular value decomposition. Previously, we have shown that SSA algorithm can equivalently be formulated as an optimality condition for the generation of adaptive ...

Wavelet frequency spectrum analysis of oscillograms

The Analyst, 1999
By combining wavelet transform with frequency spectrum analysis, wavelet frequency spectrum analysis of an oscillogram was achieved, based on the wavelet property of extracting useful information. Compared with Fourier frequency spectrum analysis of an oscillogram, this method presents many advantages.

Spectrum-frequency and genotype–phenotype analysis of rhodopsin variants

Experimental Eye Research, 2021
Mutations in RHO are the most common cause of autosomal dominant retinitis pigmentosa. However, the pathogenicity of many RHO variants is questionable. This study was designed to investigate the genotype-phenotype correlation for RHO variants. These RHO variants were collected from the in-house exome sequencing data of 7092 probands suffering from ...

Frequency spectrum analysis for spectrum stabilization in airborne gamma-ray spectrometer

Applied Radiation and Isotopes, 2014
Abnormal multi-crystal spectral drifts often can be observed when power on the airborne gamma-ray spectrometer. Currently, these spectral drifts of each crystal are generally eliminated through manual adjustment, which is time-consuming and labor-ineffective.
