Tracer Dispersion in Rough Open Cracks [PDF]

open access: yes, 1998
Tracer dispersion is studied in an open crack where the two rough crack faces have been translated with respect to each other. The different dispersion regimes encountered in rough-wall Hele-Shaw cell are first introduced, and the geometric dispersion ...

Dispersion in oscillatory flows [PDF]

open access: yes, 1983
The enhanced axial mixing which is caused by dispersion in oscillatory flows in some mass transfer devices may limit the reactor performance. This effect has provided the motivation for the present study in which oscillatory flow dispersion in a flat ...

Turbulent dispersion in cloud-topped boundary layers [PDF]

open access: yes, 2009
Compared to dry boundary layers, dispersion in cloud-topped boundary layers has received less attention. In this LES based numerical study we investigate the dispersion of a passive tracer in the form of Lagrangian particles for four kinds of atmospheric

The Dispersion Bias

open access: yesSSRN Electronic Journal, 2017
Estimation error has plagued quantitative finance since Harry Markowitz launched modern portfolio theory in 1952. Using random matrix theory, we characterize a source of bias in the sample eigenvectors of financial covariance matrices. Unchecked, the bias distorts weights of minimum variance portfolios and leads to risk forecasts that are severely ...

Bluetongue Disease Control in Northern Ireland During 2017 and 2018

open access: yesFrontiers in Veterinary Science, 2019
Since the emergence of bluetongue virus in central and northern Europe in 2006, Northern Ireland's (NI) surveillance programme has evolved to include the use of risk assessments and simulation models to monitor the risk of bluetongue incursion. Livestock
