Employing machine learning techniques in monitoring autocorrelated profiles
Neural Computing and Applications, 2023 AbstractIn profile monitoring, it is usually assumed that the observations between or within each profile are independent of each other. However, this assumption is often violated in manufacturing practice, and it is of utmost importance to carefully consider autocorrelation effects in the underlying models for profile monitoring.

Confocal laser speckle autocorrelation imaging of dynamic flow in microvasculature
Opto-Electronic Advances, 2022 Laser speckle imaging has been widely used for in-vivo visualization of blood perfusion in biological tissues. However, existing laser speckle imaging techniques suffer from limited quantification accuracy and spatial resolution.

Scattering Delay Mitigation in High-accuracy Pulsar Timing: Cyclic Spectroscopy Techniques
The Astrophysical Journal, 2023 We simulate scattering delays from the interstellar medium to examine the effectiveness of three estimators in recovering these delays in pulsar timing data. Two of these estimators use the more traditional process of fitting autocorrelation functions to

EXPLORATORY SPATIAL ANALYSIS OF HOUSING PRICES OBTAINED FROM WEB SCRAPING TECHNIQUE [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2021 The exploratory spatial analysis allows to describe patterns of spatial distribution, to identify clusters and outliers through specific techniques of spatial association and data model. The objective of the study is to verify the spatial autocorrelation

A recursive scheme for computing autocorrelation functions of decimated complex wavelet subbands [PDF]
, 2010 This paper deals with the problem of the exact computation of the autocorrelation function of a real or complex discrete wavelet subband of a signal, when the autocorrelation function (or Power Spectral Density, PSD) of the signal in the time domain (or ...

Two-photon absorption in microcavities for optical autocorrelation and sampling [PDF]
, 2003 We have designed novel semiconductor microcavity structures for the enhancement of the two-photon absorption (TPA) photocurrent. We report a TPA autocorrelation technique for short optical pulses that uses the microcavity structure instead of a second ...

Errors in radial velocity variance from Doppler wind lidar [PDF]
Atmospheric Measurement Techniques, 2016 A high-fidelity lidar turbulence measurement technique relies on accurate estimates of radial velocity variance that are subject to both systematic and random errors determined by the autocorrelation function of radial velocity, the sampling rate, and ...

Surface Orientation from Texture Autocorrelation [PDF]
, 1989 We report on a refinement of our technique for determining the orientation of a textured surface from the two-point autocorrelation function of its image. We replace our previous assumptions of isotropic texture by knowledge of the autocorrelation moment
