Hybrid CNN-BiLSTM-Attention Conditional GAN for power system forced oscillation localization
International Journal of Electrical Power & Energy SystemsData-driven methods for Forced Oscillation (FO) sources localization in power systems face challenges including limited dataset size, class imbalance, and high data acquisition costs, which limit the ability to train large and sophisticated deep learning

Neither/nor: a pragmatic philosophy for oscillating between conceptual and experiential knowledge [PDF]
Humanities & Social Sciences CommunicationsThis paper presents “Neither/Nor,” a philosophical synthesis which defines conceptual and experiential modes of knowing as complementary skills which can be deliberately trained and oscillated. The paper argues that neither theory (concepts) nor practice

Beta cell secreted GABA sets appropriate insulin secretion by modulating islet calcium oscillations [PDF]
Molecular MetabolismObjectives: Gamma-aminobutyric acid (GABA) is produced in pancreatic beta cells and is implicated in modulating islet function, yet its precise physiological role remains uncertain.

On conditions of oscillations and multi-homogeneity [PDF]
Mathematics of Control, Signals, and Systems, 2015 The main idea of this paper is to reduce the analysis of the asymptotic behavior (stability, instability, presence of oscillations related to chaos) of a nonlinear dynamical system defined by a time-invariant ordinary differential equation \[ \dot x = f(x), \qquad x\in\mathbb R^n \] to the analysis of a simpler approximating system \[ \dot x = f_0(x). \

Conditions of Self-Oscillations in Generalized Persidskii Systems [PDF]
IEEE Transactions on Automatic Control, 2022 For a class of generalized Persidskii systems, whose dynamics are described by superposition of a linear part with multiple sector nonlinearities and exogenous perturbations, the conditions of practical stability, instability and oscillatory behavior in the sense of Yakubovich are established. For this purpose the conditions of local instability at the

Oscillations in a nonlinear spring mechanism with one degree of freedom [PDF]
MATEC Web of Conferences, 2020 A new method for studying dynamics in a nonlinear spring- loaded mechanism is described, which consists in describing a spring as an elastic solid rod with conditional density and elastic modulus.

Journal of Marine Science and Engineering, 2023 The ensemble Kalman filter is often used in parameter estimation, which plays an essential role in reducing model errors. However, filter divergence is often encountered in an estimation process, resulting in the convergence of parameters to the improper

Conditions for Oscillation of a Neutral Differential Equation [PDF]
International Journal of Differential Equations, 2010 For a neutral differential equation with positive and changeable sign coefficients [x(t)−a(t)x(δ(t))]′ + p(t)F(x(τ(t))) − q(t)G(x(σ(t))) = 0, oscillation criteria are established, where q(t) is not required as nonnegative. Several new results are obtained.

Non-oscillation of half-linear differential equations with periodic coefficients
Electronic Journal of Qualitative Theory of Differential Equations, 2015 We consider half-linear Euler type differential equations with general periodic coefficients. It is well-known that these equations are conditionally oscillatory, i.e., there exists a border value given by their coefficients which separates oscillatory ...
