Dynamical Approach in studying GJR-GARCH (Q,P) Models with Application
Tikrit Journal of Pure Science, 2022 This paper deals with finding stationarity Condition of GJR-GARCH(Q,P) model by using a local linearization technique in order to reduce this non-linear model to a linear difference equation with constant coefficients and then obtain the stationarity ...

Blazar Variability: A Study of Non-stationarity and the Flux-RMS Relation
, 2020 We analyze X-ray light curves of the blazars Mrk 421, PKS 2155-304, and 3C 273 using observations by the Soft X-ray Telescope on board AstroSat and archival XMM-Newton data.

Anais da Academia Brasileira de Ciências, 2022 Estimating the probability of occurrence of extreme hydrologic events is a fundamental input in the design of hydraulic infrastructure. The classical approach to this problem has been to fit parametric probability functions to annual maxima streamflow ...

Non-Stationarity-Based Adaptive Segmentation Applied to Voice Disorder Discrimination
IEEE Access, 2023 Voice disorders can affect people in all age groups. Vocal health is especially important when voice is used as a work tool, as in the fields of education (teachers), music (singers) and multimedia (journalists).

Non-Stationarities in Extra-Large-Scale Massive MIMO [PDF]
IEEE Wireless Communications, 2020 Massive MIMO, a key technology for increasing area spectral efficiency in cellular systems, was developed assuming moderately sized apertures. In this paper, we argue that massive MIMO systems behave differently in large-scale regimes due to spatial non-stationarity.

The power of surrogate data testing with respect to non-stationarity
, 1998 Surrogate data testing is a method frequently applied to evaluate the results of nonlinear time series analysis. Since the null hypothesis tested against is a linear, gaussian, stationary stochastic process a positive outcome may not only result from an ...

Brans-Dicke gravity and the capture of stars by black holes: some asymptotic results
, 2004 In the context of star capture by a black hole, a new noticeable difference between Brans-Dicke theory and general relativity gravitational radiation is pointed out.

Bell's inequality violation due to misidentification of spatially non stationary random processes
, 2003 Correlations for the Bell gedankenexperiment are constructed using probabilities given by quantum mechanics, and nonlocal information. They satisfy Bell's inequality and exhibit spatial non stationarity in angle.

The relevance of non-stationarities and non-Gaussianities in vibration fatigue
MATEC Web of Conferences, 2018 In classical fatigue of materials, the frequency contents of dynamic loading are well below the natural frequencies of the observed structure or test specimen.
