A Wavefield-Domain Method for Refining Residual Timing Errors in Passive-Source Seismic Exploration [PDF]
SensorsIn passive-source seismic exploration, even after seismic instruments complete unified start-up acquisition and hardware synchronization, long-duration continuous records may still contain small residual timing errors, which in turn broaden cross ...

Characteristic functions for cosmological cross-correlations
Monthly Notices of the Royal Astronomical Society, 2023 ABSTRACT We introduce a novel unbiased, cross-correlation estimator for the one-point statistics of cosmological random fields. One-point statistics are a useful tool for analysis of highly non-Gaussian density fields, while cross-correlations provide a powerful method for combining information from pairs of fields and separating them ...

Introduction and application of transfer function model to predict the process of rainfall-groundwater level in Golestan province [PDF]
رویکردهای نوین در مهندسی آب و محیط زیست, 2023 Groundwater is one of the most valuable water resource in Iran, which is mainly influenced by rainfall patterns in a region. In the present study, 30-years rainfall and groundwater level data were used in the three watersheds of Galikesh, Ramian and ...

Generation and validation of a PREP sample response
Current Directions in Biomedical Engineering, 2023 PREP are typical signal courses in the EEG, which are used to investigate the influence of neuropathologies or, for example, post-traumatic headaches on pain processing. The medically meaningful peaks are detected manually for further analysis.

Optimal Stacking of Noise Cross-Correlation Functions
Geophysical Journal International, 2022 SUMMARY Cross-correlations of ambient seismic noise are widely used for seismic velocity imaging, monitoring and ground motion analyses. A typical step in analysing noise cross-correlation functions (NCFs) is stacking short-term NCFs over longer time periods to increase the signal quality.

Understanding volatility correlation behavior with a magnitude cross-correlation function [PDF]
Physical Review E, 2006 We propose an approach for analyzing the basic relation between correlation properties of the original signal and its magnitude fluctuations by decomposing the original signal into its positive and negative fluctuation components. We use this relation to understand the following phenomenon found in many naturally occurring time series: the magnitude of
