Proceedings ArticleDOI
Blackout mitigation assessment in power transmission systems
TL;DR: While the absolute frequency of disruptions of all sizes may be reduced, the underlying forces can still cause the relative frequency of large disruptions to small disruptions to remain the same, and efforts to mitigate small disruptions can even increase the frequency ofLarge disruptions.

Scaling fields in the two-dimensional Abelian sandpile model.
Stephane Mahieu,Philippe Ruelle +1 more
TL;DR: It is found that perfect agreement with the predictions of a c=-2 conformal field theory and its massive perturbation is found, thereby providing direct evidence for conformal invariance and more generally for a description in terms of a local field theory.
Journal ArticleDOI
Waiting-Time Statistics of Self-Organized-Criticality Systems
TL;DR: It is argued that a system governed by self-organized-criticality (SOC) dynamics can lack Poisson waiting-time statistics not only when the experimental resolution lies within the self-similar scale range but also if the system is slowly driven in a correlated way.
Journal ArticleDOI
Dislocation avalanches: Role of temperature, grain size and strain hardening
TL;DR: In this article, the authors investigate the possible incidence of temperature and microstructure on the emerging pattern of the scale-free pattern of an avalanche, and reveal the role of grain boundaries as barriers to dislocation motion hindering the emergence of the scalesafe pattern.
Journal ArticleDOI
Avalanches and Scaling in Plastic Deformation
TL;DR: This model of dislocation loops using an analytically solvable phase-field model of dislocations for ductile single crystals during monotonic loading predicts a range of macroscopic behaviors in agreement with observation, including hardening with monotony loading, and a maximum in the acoustic emission signal at the onset of yielding.
