Persistence and discontinuity in the VIX dynamics

Chaos, Solitons & Fractals, 2018
Abstract We estimate the two Mandelbrotian parameters (“dual forms of wild variability”), namely, long-range dependence (Joseph effect) and discontinuity or fat tails (Noah effect) for the VIX stock market volatility measure. We find the VIX scalar series to be characterized by strong dependence (with nonstationary but mean-reverting dynamics) and ...

Determination of statistical discontinuity persistence for a rock mass characterized by non-persistent fractures

International Journal of Rock Mechanics and Mining Sciences, 2019
Abstract The discontinuity persistence is an important parameter that affects the strength of rock masses and stability in rock engineering. However, determining the 3D discontinuity persistence in practical field projects remains difficult.

The effect of discontinuity persistence on rock slope stability [PDF]

International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1983
Discontinuity persistence has a major effect on rock mass resistance (strength) but, as direct mapping of discontinuities internal to a rock mass is not possible, persistence is a difficult parameter to measure. As a result, the conservative approach of assuming full persistence is often taken. In this paper a method is developed for relating rock mass

Using DFN Logic in Open Pit Stability Analysis Applications for Calibration and Predictive Calculation Including Defined Persistence Discontinuities

All Days, 2022
In open pit stability analyses, numerical modeling helps to evaluate failure modes related to the interaction between discontinuities and the rock mass.
