Investigation of changes in Briksdalsbreen, western Norway from 1966 - 2020
(Master thesis, 2023-02-06)Briksdalsbreen in western Norway was studied using remote sensing. Sets of optical aerial photographs captured between 1966 to 2020 were used with LiDAR-based Digital Elevation Models (DEMs) and glacier outlines derived ... -
Investigation of crustaceans from shelf areas in the Gulf of Guinea, with special emphasis on Brachyura
(Master thesis, 2009)Crustacean abundance on continental shelves off Nigeria, Cameroon and Gabon in the Gulf of Guinea was investigated in this study. Quantitative data was sampled with a 0.1 m² Van Veen grab during a survey with RV Dr. Fridtjof ... -
Investigation of Gas Adsorption and Separation Properties in the Metal-Organic Framework CPO-54-Co
(Master thesis, 2022-06-01) -
Investigation of gaseous ammonia for NOx control by SCR on an experimental basis
(Master thesis, 2016-08-15)My dissertation argues which of the two reducing agents, urea or pure ammonia, is better suited for reducing NOx emissions in Marine SCR applications. While the question might seem straight forward, there are several upsides ... -
Investigation of growth performance of post-smolt Atlantic salmon (Salmo salar L.) in semi closed containment system: A big-scale benchmark study
(Journal article; Peer reviewed, 2022)The Norwegian salmon industry faces challenges related to sea lice (Lepeophtheirus salmonis) infestations, escapees, diseases and environmental impact. Semi-closed containment systems (S-CCS) have been proposed to abate ... -
Investigation of instability and turbulence effects on gas explosions: experiments and modelling
(Doctoral thesis, 2018-03-09)Safe design of industrial facilities requires models that can predict the consequences of accidental gas explosions in complex geometries with sufficient accuracy. Computa- tional fluid dynamics (CFD) models are widely ... -
Investigation of long-wave model equations for a liquid CO2-seawater interface in deep water
(Master thesis, 2017-11-04) -
Investigation of Low Salinity Polymer and Surfactant Flooding in Carbonate Reservoir at Reservoir Conditions
(Master thesis, 2018-04-20)It is estimated that 40-60% of the world’s total hydrocarbon production is from carbonate rocks [1]. Carbonate rocks contain the world`s largest fields in the Middle East (i.e., Ghawar Field, Saudi Arabia). Waterflooding ... -
Investigation of nanofluids in alkaline electrolytes: Stability, electrical properties, and hydrogen production
(Journal article; Peer reviewed, 2023)Utilizing solar energy efficiently and manufacturing hydrogen economically are the primary goals in the energy industry. In this paper, we present a novel method to solve both issues by exploiting the electrolysis of ... -
Investigation of nonlinear effects in piezoelectric discs and radiated sound field
(Master thesis, 2023-06-01) -
Investigation of offshore wind turbine wakes by numerical modeling and full-scale measurements
(Doctoral thesis, 2024-04-30)Bak en vindturbin rotor som trekker kinetisk energi ut fra luftstrømmen, blir strømningsforholdene endret. Dette området kalles vindturbinens vake. Vaken er karakterisert av redusert vindhastighet og økt turbulensintensitet. ... -
Investigation of Particle Trajectories and Flow Patterns in a Hydrocyclone by Positron Emission Particle Tracking (PEPT)
(Master thesis, 2012-05-31)Cyclone separators are widely used for separation of solids or droplets from gaseous or liquid fluids in several industries. Cyclones can be used for many purposes and each cyclone can be fitted to its area of use. In the ... -
Investigation of serum protein profiles in scrapie infected sheep by means of SELDI-TOF-MS and multivariate data analysis
(Peer reviewed; Journal article, 2013-11-14)Background: Classical scrapie in sheep is a fatal neurodegenerative disease associated with the conversion PrPC to PrPSc. Much is known about genetic susceptibility, uptake and dissemination of PrPSc in the body, but many ... -
An Investigation of Single Wind Turbine Wakes with Static LiDAR Wind Profilers
(Master thesis, 2016-06-01)Three static LiDAR wind profilers were deployed during the seven month field experiment WINTWEX-W at ECN's test site in Wieringermeer. The campaign was focused on capturing the structure and dynamics of the wake of a NORDEX ... -
An investigation of the correlation between interfacial properties and phase composition in the crude oil/water system
