$1/f$ noise and avalanche scaling in plastic deformation [PDF]
, 2006 We study the intermittency and noise of dislocation systems undergoing shear deformation. Simulations of a simple two-dimensional discrete dislocation dynamics model indicate that the deformation rate exhibits a power spectrum scaling of the type $1/f ...

Avalanche character and fatalities in the high mountains of Asia
Annals of Glaciology, 2016 With the exception of northern India, there are few, if any, consistent data records relating to avalanche activity in the high mountains of Asia. However, records do exist of avalanche fatalities in the region, contained in mountaineering expedition ...

Acoustic Emission Spectroscopy: Applications in Geomaterials and Related Materials
Applied Sciences, 2021 As a non-destructive testing technology with fast response and high resolution, acoustic emission is widely used in material monitoring. The material deforms under stress and releases elastic waves.

Spatial Determination of Magnetic Avalanche Ignition Points
, 2007 Using time-resolved measurements of local magnetization in the molecular magnet Mn12-ac, we report studies of the propagation of magnetic avalanches (fast magnetization reversals) that originate from points inside the crystals rather than at the edges ...

Transition rates for slip-avalanches in soft athermal disks under quasi-static simple shear deformations [PDF]
, 2018 We study slip-avalanches in two-dimensional soft athermal disks by quasi-static simulations of simple shear deformations. Sharp drops in shear stress, or slip-avalanches, are observed intermittently during steady state.

Intrinsic avalanches and collective phenomena in a Mn(II)-free radical ferrimagnetic chain
, 2008 Magnetic hysteresis loops below 300 mK on single crystals of the Mn(II) - nitronyl nitroxide free radical chain (Mn(hfac)_2({\it R})-3MLNN) present abrupt reversals of the magnetization, or avalanches.

Singularities and Avalanches in Interface Growth with Quenched Disorder
, 1995 A simple model for an interface moving in a disordered medium is presented. The model exhibits a transition between the two universality classes of interface growth phenomena. Using this model, it is shown that the application of constraints to the local

High and very high avalanche risk during 2016-2017 winter season [PDF]
Aerul şi Apa: Componente ale Mediului, 2018 The paper presents and analyze snow and meteorological conditions of 2016-2017 winter, which led to the estimation of high and very high avalanche risk in Bucegi and Făgăraş Mountains, the two areas covered by nivological program of the Romanian National

From waves to avalanches: two different mechanisms of sandpile dynamics
, 2000 Time series resulting from wave decomposition show the existence of different correlation patterns for avalanche dynamics. For the d=2 Bak-Tang-Wiesenfeld model, long range correlations determine a modification of the wave size distribution under coarse ...

Two scenarios for avalanche dynamics in inclined granular layers
, 2005 We report experimental measurements of avalanche behavior of thin granular layers on an inclined plane for low volume flow rate. The dynamical properties of avalanches were quantitatively and qualitatively different for smooth glass beads compared to ...
