chemical oscillationsBelousov‐Zhabotinsky reactionnonlinear chemical dynamicsA method of time-frequency transformations of nonstationary signals has been discussed and applied to the analysis of oscillatory Belousov - Zhabotinsky (BZ) reaction. Selected registers of BZ reactions, that represent regular and ...
Time-frequency analysis (TFA) for mechanical vibrations in non-stationary operations is the main subject of this article, concisely written to be an introducing tutorial comparing different time-frequency techniques for non-stationary signals. The theory was carefully exposed and complemented with sample ...
In this paper the simulation analysis methord of PSS/E dynamic simulation and small signal stability is introduced.Using the two areas with four generators as example,the factors which influenc low frequency oscillation induding the power transferred by tie line,type and parameters of excitation syste...

The effects of quartic anharmonicity on the quantum dynamics of a linear oscillator with time-dependent force constant (K) or harmonic frequency...
In this study, a data-driven approach employed by utilizing the product called JRC-Global surface water mapping layers V1.4 on the Google Earth Engine (GEE) to map and monitor the effects of climate change on surface water resources. Key climatic variabl
For |τ| > 0, Rabi oscillations are apparent. e, Temporal two-photon wavefunctions of the coherent and incoherent component, α(2)(τ) and ϕ(2)(τ), respectively, where ϕ(2)(0) = −α(2)(τ). f, Two-photon wavefunctions in the frequency domain. The coherent ...
Bergey a,Jaroslaw Harezlak b,Christophe C. Jouny a 摘要: Objective We investigate the relevance of high frequency oscillations (HFO) for biomarkers of epileptogenic tissue and indicators of preictal state before complex partial seizures in humans. Methods We introduce a novel automated HFO detection...
Application of Dynamic Time-frequency Analysis for Voltage Stability in Power System Network By combining wavelet transform (WT) with fractal theory, a novel approach is put forward to detect early short-circuit fault. The application of signal den... S Kang,J Chen,X Song,... - Second Intern...
Temperature oscillations in the atmosphere, ocean, and coupled atmosphere–ocean system occur on a variety of time scales, ranging from multi-year to multi-decadal periods. In this work, we focus on long-period oscillations with periods beyond the 11-year solar cycle. One oscillation that is fr...
