Unified Green's function retrieval by cross correlation.
It has been shown by many authors that the cross correlation of two recordings of a diffuse wave field at different receivers yields the Green's function between these receivers. Recently the theory has been extended for situations where time-reversal invariance does not hold (e.g., in attenuating media) and where source-receiver reciprocity breaks down (in moving fluids). Here we present a uni...
متن کاملUnified Green's function retrieval by cross-correlation; connection with energy principles.
It has been shown theoretically and observationally that the Green's function for acoustic and elastic waves can be retrieved by cross-correlating fluctuations recorded at two locations. We extend the concept of the extraction of the Green's function to a wide class of scalar linear systems. For systems that are not invariant under time reversal, the fluctuations must be excited by volume sourc...
متن کاملElectromagnetic Green’s functions retrieval by cross-correlation and cross-convolution in media with losses
[1] It is shown that the electromagnetic Green’s functions of any linear medium with arbitrary heterogeneity can be obtained from the cross-correlation, or the crossconvolution, of two recordings at different receiver locations in an open system. Existing representations are known for cross-correlations where time-reversal invariance is exploited and hence they are considered in lossless media....
متن کاملThe Galaxy–Absorber Cross-Correlation Function
We describe an analysis of the galaxy–absorber cross-correlation function ξga(v, ρ) as a function of velocity separation v, impact parameter separation ρ, and absorber Lyα equivalent width W on impact parameter scales that extend up to ≈ 1 h Mpc.
متن کاملCross - lingual Information Retrieval Model based on Bilingual Topic Correlation ⋆
How to construct relationship between bilingual texts is important to effectively processing multi-lingual text data and cross language barriers. Cross-lingual latent semantic indexing (CL-LSI) corpus-based doesnot fully take into account bilingual semantic relationship. The paper proposes a new model building semantic relationship of bilingual parallel document via partial least squares (PLS)....
