On one approximate method for recovering a function from its autocorrelation function
Известия высших учебных заведений. Поволжский регион: Физико-математические науки, 2022 Background. When solving many physical and technical problems, a situation arises when only operators (functionals) from the objects under study (signals, images, etc.) are available for observations (measurements). It is required to restore the object

Decorrelation scales for Arctic Ocean hydrography – Part I: Amerasian Basin [PDF]
Ocean Science, 2018 Any use of observational data for data assimilation requires adequate information of their representativeness in space and time. This is particularly important for sparse, non-synoptic data, which comprise the bulk of oceanic in situ observations in ...

Autocorrelation function of eigenstates in chaotic and mixed systems [PDF]
, 2001 We study the autocorrelation function of different types of eigenfunctions in quantum mechanical systems with either chaotic or mixed classical limits. We obtain an expansion of the autocorrelation function in terms of the correlation length.

Nature of self-diffusion in two-dimensional fluids [PDF]
, 2017 Self-diffusion in a two-dimensional simple fluid is investigated by both analytical and numerical means. We investigate the anomalous aspects of self-diffusion in two-dimensional fluids with regards to the mean square displacement, the time-dependent ...

On the Statistical Analysis of the Harmonic Signal Autocorrelation Function
International Journal of Applied Mathematics and Computer Science, 2021 The article presents new tools for investigating the statistical properties of the harmonic signal autocorrelation function (ACF). These tools enable identification of the ACF estimator errors in measurements in which the triggering of the measurements ...
