Reliability of sampling designs for spatial snow surveys
Computers & Geosciences, 2007Spatial patterns are an inherent property of most naturally occurring materials at a large range of scales. To describe spatial patterns in the field, several observations are made according to a certain sampling design. The spatial structure can be described by the semivariogram range, and nugget and sill variances. We test how reliably seven sampling

, 2014 Climate change has been and increasingly will be a major threat to the ski tourism industry whose survival is highly dependent on existence of snow cover of sufficient depth and duration. The common knowledge requires that in order for a ski resort to be viable, it has to perform operations for at least 100 days in seven out of ten winters.

Failures of Roofs under Snow Load: Causes and Reliability Analysis
Forensic Engineering 2009, 2009Collapses of a number of roofs in Europe during the winter 2005/2006 initiated discussions concerning reliability of the roofs exposed to snow loads. Presented overview of extensive investigations of structural failures is focused on causes and consequences of failures.

Effect of Statistical Uncertainties in Ground Snow Load on Structural Reliability
IABSE Reports, 2015<p>This paper studies the effect of commonly neglected statistical uncertainties on structural reliability. The failure probability of a generic structural member, subjected to snow load is analysed using frequentist and Bayesian techniques to quantify parameter estimation and model selection uncertainties in ground snow load. Various variable to

Is the extreme snow depth record for nordland, norway reliable?
Geografiska Annaler: Series A, Physical Geography, 2016A snow depth of 370 cm at Dunderlandsdalen in winter 1919–20 is the largest recorded at stations in Nordland, Norway. During the period 1895–1924, the average maximum annual value there was 150.4 cm; at other stations it ranged from 38.5 to 190.1 cm. The ratio of maxima at other stations to that at Dunderlandsdalen was particularly low in 1919–20.

Reliability of Steel Hall in Zenica Loaded by Snow Load
2019Snow load is the dominant load for steel structures of hall in Zenica, Bosnia and Herzegovina. Existing structures are calculated in accordance with the JUS regulations that were valid in the former Yugoslavia. The snow load was based on the values proposed in the DIN regulations of 1936 and used until the development of new regulations according to ...

Reliability Analysis of Snow Depth Monitoring System Based on Improved FMECA
2016Aiming at the problems of low accuracy and strong subjectivity in reliability analysis based on FMECA, the fuzzy theory and VIKOR theory methods are applied in criticality analysis in FMECA technique. Firstly, fuzzy decision matrix of risk factors based on fuzzy theory is built, in which fuzziness is removed by barycenter method, and specific ...
