Analysis of common-azimuth migration for vertically layered media shows that downward continuing the data in a narrow strip around the zero crossline offset should yield a kinematically correct migration scheme. I introduce two migration methods that exploit the common-azimuth equations to define an optimal range of crossline-offset wavenumbers and thus to minimize the number of crossline offse...
A common method for constructing blending Dupin cyclides for two cones having a common inscribed sphere of radius r > 0 involves three steps: (1) computing the (−r)-offsets of the cones so that they share a common vertex, (2) constructing a blending cyclide for the offset cones, and (3) computing the r-offset of the cyclide. Unfortunately, this process does not always work properly. Worse, for ...
Recording anomalous traces in business processes diminishes an event log?s quality. The abnormalities may represent bad execution, security issues, or deviant behavior. Focusing on mitigating this phenomenon, organizations spend efforts to detect their save resources and improve process execution. However, many real-world environments, reference models are unavailable, requiring expert assistan...
Wave-equation migration with the velocity of the primaries maps non-diffracted waterbottom multiples to an hyperbola in subsurface-offset-domain-common-image-gathers. Furthermore, for positive surface offsets, the multiples are mapped to non-positive subsurface offsets if sediment velocity is faster than water. The larger the offset in the data space, the larger the subsurface offset and the sh...
On the one hand, a large number of companies have committed to achieve net zero emissions and many them foresee offset some remaining with carbon credits, suggesting surge future demand. Yet, supply side voluntary market is struggling align its business model new legal architecture Paris Agreement. This article juxtaposes these two perspectives. It provides an overview plans 482 major form neut...
I introduce a digital wavelet-like transform tailored specifically for representing seismic data. The transform provides a multiscale orthogonal basis with basis functions aligned along seismic event slopes in the input data. It is defined with the help of the wavelet lifting scheme combined with local plane-wave destruction. The main objective of the new “seislet” transform is an optimal seism...
Invariant feature detectors and descriptors are a common tool now for many computer vision tasks. Recently, fast and efficient variants such as BRISK were developed to offset the computational burden of traditional invariant descriptors such as SIFT. A common thread in invariant descriptors is affine invariance which improves matching performance in large baseline situations. In this work we de...
We present high spatial resolution 21 cm HI maps of the interacting galaxy pair NGC 7714/7715. We detect a massive (2 × 109M⊙) HI bridge connecting the galaxies that is parallel to but offset from the stellar bridge. A chain of HII regions traces the gaseous bridge, with Hα peaks near but not on the HI maxima. An HI tidal tail is also detected to the east of the smaller galaxy NGC 7715, similar...
