Persistent memory of diffusing particles

6 years ago

AbstractThe variance of the advection-diffusion processes with variable coefficients is exactly decomposed as a sum of dispersion terms and memory…

Spatially inhomogeneous transition probabilities as memory effects for diffusion in statistically homogeneous random velocity fields

6 years ago

AbstractWhenever one uses translation invariant mean Green’s functions to describe the behavior in the mean and to estimate dispersion coefficients for…

Accuracy of numerical simulations of contaminant transport in heterogeneous aquifers: A comparative study

6 years ago

AbstractThis work deals with a comparison of different numerical schemes for the simulation of contaminant transport in heterogeneous porous media.…

A mixed finite element discretization scheme for a concrete carbonation model with concentration-dependent porosity

6 years ago

AbstractWe investigate a prototypical reaction–diffusion-flow problem in saturated/unsaturated porous media. The special features of our problem are twofold: the reaction produces…

Solute transport in aquifers with evolving scale heterogeneity

6 years ago

AbstractTransport processes in groundwater systems with spatially heterogeneous properties often exhibit anomalous behavior. Using first-order approximations in velocity fluctuations we…

Consistency issues in PDF methods

6 years ago

AbstractConcentrations of chemical species transported in random environments need to be statistically characterized by probability density functions (PDF). Solutions to evolution equations…

A Fokker-Planck approach for probability distributions of species concentrations transported in heterogeneous media

6 years ago

AbstractWe identify sufficient conditions under which evolution equations for probability density functions (PDF) of random concentrations are equivalent to Fokker–Planck…

Towards a filtered density function approach for reactive transport in groundwater

6 years ago

AbstractEvolution equations for probability density functions (PDFs) and filtered density functions (FDFs) of random species concentrations weighted by conserved scalars…

Influence of deterministic trend on the estimated parameters of GARCH(1,1) model

6 years ago

AbstractThe log returns of financial time series are usually modeled by means of the stationary GARCH(1,1) stochastic process or its…

Serial correlation of detrended time series

6 years ago

AbstractA preliminary essential procedure in time series analysis is the separation of the deterministic component from the random one. If…
