Cellular-Automata model for dense-snow avalanches [PDF]

, 2007
This paper introduces a three-dimensional model for simulating dense-snow avalanches, based on the numerical method of cellular automata. This method allows one to study the complex behavior of the avalanche by dividing it into small elements, whose ...

Wind conditions for snow cornice formation in a wind tunnel [PDF]

The Cryosphere, 2023
Snow cornices growing on the leeward side of mountain ridges are common in alpine and polar regions during snow seasons. These structures may crack and fall, leading to an increase in avalanche danger. Although cornice formation has been observed in wind

Beyond quantum mechanics? Hunting the 'impossible' atoms (Pauli Exclusion Principle violation and spontaneous collapse of the wave function at test) [PDF]

, 2015
The development of mathematically complete and consistent models solving the so-called "measurement problem", strongly renewed the interest of the scientific community for the foundations of quantum mechanics, among these the Dynamical Reduction Models ...

Snow-Collection Mechanisms and the Capacities of Snow Fences [PDF]

Annals of Glaciology, 1989
The shapes of equilibrium lee drifts formed by snow fences are scaled in proportion to height of snow fences independent of the snow and weather conditions, even in small-scale models, but those of up-wind drifts are not.Field studies have been made of the snow-collection mechanisms of a snow fence.

Acoustic emission signatures prior to snow failure

Journal of Glaciology, 2018
Snow slab avalanches are caused by cracks forming and propagating in a weak snow layer below a cohesive slab. The gradual damage process leading to the formation of the initial failure within the weak layer (WL) is still not entirely understood.

The effect of propagation saw test geometries on critical cut length [PDF]

Natural Hazards and Earth System Sciences
For a slab avalanche to release, a crack in a weak snow layer beneath a cohesive snow slab has to initiate and propagate. Information on crack propagation is essential for assessing avalanche triggering potential.

Seismic observations of a complex firn structure across the Amery Ice Shelf, East Antarctica

Journal of Glaciology, 2021
We use seismic refraction data to investigate the firn structure across a suture zone on the Amery Ice Shelf, East Antarctica, and the possible role of glacier dynamics in firn evolution.

High sensitivity tests of the Pauli Exclusion Principle with VIP2 [PDF]

, 2015
The Pauli Exclusion Principle is one of the most fundamental rules of nature and represents a pillar of modern physics. According to many observations the Pauli Exclusion Principle must be extremely well fulfilled.

Numerical study of fracture arrest on snow cover

Fracture and Structural Integrity, 2013
Under the hypothesis of a perfectly brittle phenomenon, avalanche triggering can be investigated numerically by means of Linear Elastic Fracture Mechanics (LEFM).
