Analysis and Research on Chaotic Dynamics of Evaporation Duct Height Time Series with Multiple Time Scales

open access: yesAtmosphere, 2022
The evaporation duct is a particular type of atmospheric structure that always appears on the open ocean. Predicting the evaporation duct height (EDH) accurately and in a timely manner is of great significance for the practical application of marine ...

Stationary relativistic jets [PDF]

open access: yesComputational Astrophysics and Cosmology, 2015
AbstractIn this paper we describe a simple numerical approach which allows to study the structure of steady-state axisymmetric relativistic jets using one-dimensional time-dependent simulations. It is based on the fact that for narrow jets with $v_{z}\approx c$ v z

A Blockwise Empirical Likelihood Test for Gaussianity in Stationary Autoregressive Processes

open access: yesMathematics, 2023
A new and simple blockwise empirical likelihood moment-based procedure to test if a stationary autoregressive process is Gaussian has been proposed. The proposed test utilizes the skewness and kurtosis moment constraints to develop the test statistic ...

Forecasting with difference-stationary and trend-stationary models [PDF]

open access: yes, 2000
Summary: Although difference-stationary (DS) and trend-stationary (TS) processes have been subject to considerable analysis, there are no direct comparisons for each being the data-generation process (DGP). We examine incorrect choice between these models for forecasting for both known and estimated parameters.
