Insight on Invasions and Resilience Derived from Spatiotemporal Discontinuities of Biomass at Local and Regional Scales

open access: yesEcology and Society, 2012
Understanding the social and ecological consequences of species invasions is complicated by nonlinearities in processes, and differences in process and structure as scale is changed. Here we use discontinuity analyses to investigate nonlinear patterns in

Stability Assessment of Rock Slopes in the Former Quarry of Wojciech Bednarski Park in Kraków—A Case Study

open access: yesApplied Sciences
This study presents a stability assessment of rock slopes, considering the joint systems of the rock walls of Wojciech Bednarski Park. Special emphasis was placed on analysing the orientation and infill characteristics of the identified joint sets. Based

Panarchy: Discontinuities Reveal Similarities in the Dynamic System Structure of Ecological and Social Systems

open access: yesEcology and Society, 2009
In this paper, we review the empirical evidence of discontinuous distributions in complex systems within the context of panarchy theory and discuss the significance of discontinuities for understanding emergent properties such as resilience.

On the modeling of sound propagation over multi-impedance discontinuities using a semiempirical diffraction formulation [PDF]

open access: yes, 2006
Several approximate extensions of the semi-empirical De Jong model [ De Jong et al., J. Sound and Vib. 86, 23–46 (1983) ] are considered for the prediction of sound propagation over multiple impedance discontinuities.

Level Set Methods for Stochastic Discontinuity Detection in Nonlinear Problems

open access: yes, 2019
Stochastic physical problems governed by nonlinear conservation laws are challenging due to solution discontinuities in stochastic and physical space. In this paper, we present a level set method to track discontinuities in stochastic space by solving a ...
