Chaotic Advection at the Pore Scale: Mechanisms, Upscaling and Implications for Macroscopic Transport [PDF]
, 2016 The macroscopic spreading and mixing of solute plumes in saturated porous media is ultimately controlled by processes operating at the pore scale. Whilst the conventional picture of pore-scale mechanical dispersion and molecular diffusion leading to ...

Frequency-Domain Q-Compensated Reverse Time Migration Using a Stabilization Scheme
Remote Sensing, 2022 Seismic attenuation occurs during seismic wave propagation in a viscous medium, which will result in a poor image of subsurface structures. The attenuation compensation by directly amplifying the extrapolated wavefields may suffer from numerical ...

Chemical Measurement and Fluctuation Scaling [PDF]
, 2016 Main abstract: Fluctuation scaling reports on all processes producing a data set. Some fluctuation scaling relationships, such as the Horwitz curve, follow exponential dispersion models which have useful properties. The mean-variance method applied to

A Convergence Theorem for Bivariate Exponential Dispersion Models [PDF]
Journal of Mathematics and Statistics, 2019 Multivariate exponential dispersion models (MEDMs) were defined in 2013 by Jorgensen and Martinez. A particular case of MEDM is the bivariate Gamma model; in this article we prove that, under certain conditions, this is a limit distribution for MEDM generated by bivariate regularly varying measures, extending a previous result given by the ...

Surface gravity waves on randomly irregular floor and the telegrapher’s equation
AIP Advances, 2021 The simplest model for the evolution of the mean-value of a surface gravity wave propagating in a random bottom has been connected with the telegrapher’s equation.

Spatial Tweedie exponential dispersion models
, 2020 This paper proposes a general modeling framework that allows for uncertainty quantification at the individual covariate level and spatial referencing, operating withing a double generalized linear model (DGLM). DGLMs provide a general modeling framework allowing dispersion to depend in a link-linear fashion on chosen covariates.

Risks, 2021 This article presents the Exponential–Generalized Inverse Gaussian regression model with varying dispersion and shape. The EGIG is a general distribution family which, under the adopted modelling framework, can provide the appropriate level of ...

AM 1934-563: A giant spiral polar-ring galaxy in a triplet [PDF]
, 2005 We have observed the emission-line kinematics and photometry of a southern triplet of galaxies. The triplet contains a giant spiral galaxy AM 1934-563 which optical structure resembles a polar-ring galaxy: distorted spiral disk, seen almost edge-on, and ...
