Numerical solutions for nonlinear high damping rubber bearing isolators: Newmark's method with Netwon-Raphson iteration revisited
(Peer reviewed; Journal article, 2018)Numerical methods for the solution of dynamical problems in engineering go back to 1950. The most famous and widely-used time stepping algorithm was developed by Newmark in 1959. In the present study, for the first time, ... -

Nutrient effect of various composting methods with and without biochar on soil fertility and maize growth
(Journal article; Peer reviewed, 2019)This work showed for the first time that organic nutrient transformation techniques based on locally available materials (manure, green waste and advanced biochar) can increase fertilizing efficiency of the resulting ... -
NVE Grasdalen snøforskning. Resultater av målinger på mast. Vinterene 1979 til 1986
(NGI-rapport;58110-04, Research report, 1987-05-04)Denne rapporten inneholder en kort beskrivelse av instrumenteringen på masten, de malte stålspenningene gjennom vinterene 1979 til 1986, de utregnede aksiallastene og bøyemomentene, samt en kort vurdering av resultatene. -

Nye boligområder ofte skredutsatt: Fareområder må registreres før planer fastlegges
(Journal article, 1981)I mange av våre bratte fjellsider, særlig på Vestlandet og i Nord-Norge er skred en reell fare. Ny bebyggelse blir ofte plassert i mer skredutsatte strøk. Dette ble bl.a. konstatert skredvinteren 1978/79. Bygningsloven ... -
Objective comparison of two to three dimensional avalanche model output and field data using the AIMEC approach
(The International Snow Science Workshop (ISSW) Proceedings;, Chapter, 2012)In recent years two to three dimensional avalanche simulation tools have gained importance to estimate the hazard. The models are optimized to determine run out distances of avalanches. However, technically dynamic models ... -
Observations of preferential summer melt of Arctic sea-ice ridge keels from repeated multibeam sonar surveys
(Peer reviewed; Journal article, 2023)Sea-ice ridges constitute a large fraction of the total Arctic sea-ice area (up to 40 %–50 %); nevertheless, they are the least studied part of the ice pack. Here we investigate sea-ice melt rates using rare, repeated ... -
Observations of the dynamic structure of snow avalanches
(Journal article, 1993)During two winters, 1990–92, the dynamic structures of snow avalanches were studied in western Norway. Artificially released wet-snow avalanches ran down the avalanche chute and stopped in front of the retaining dam. Running ... -
Observations on water level fluctuations in snow due to rain and snowmelt
(Chapter, 1996)Meteorological parameters, snowpack conditions and water level fluctuations in snowpack due to rain and snowmelt, have been registered during 5 winters at two slushflow sites in Rana, North Norway. A noticeable rise of ... -

On avalanche (front) velocity measurements at the Ryggfonn avalanche test site and comparison with observations from other locations
(The International Snow Science Workshop (ISSW) Proceedings;, Chapter, 2012)Besides the runout distance of an avalanche, information on avalanche intensity along the path are often required for hazard zoning or planning of mitigation measures. The avalanche (front) velocity is a common measure as ... -
On avalanche measurements at the Norwegian full-scale test-site Ryggfonn.
(The International Snow Science Workshop (ISSW) Proceedings;, Chapter, 2008)Avalanche measurements and observations, which were carried out at the Ryggfonn test-site, Norway, on 16 April 2005, are analyzed. The data include pulsed Doppler radar measurements, impact pressure readings from load cells ...
