Calculating expected effects of treatment effectivity and river flow rates on the contribution of WWTP effluent to the ARG load of a receiving river
(Peer reviewed; Journal article, 2021)Concentrations of genetic markers for antibiotic resistance genes (ARGs) were measured in the effluents of three Norwegian wastewater treatment plants (WWTPs) and in a receiving river upstream and downstream of the discharge ... -
Calculating Hourly Cost Rates In Project-Based Industries Part 2: cost management
(Peer reviewed; Journal article, 2020)Hourly cost rates are crucial project costing due to the substantial proportion of labor costs in projects. Yet, there is little published about calculating hourly cost rates, and it is a contentious topic in corporations. ... -
Calculation and evaluation of crack risk in hardening concrete structures: Effects of thermal dilation, autogenous shrinkage and structural restraint on culverts
(Master thesis, 2011)This thesis deals with prediction of early age cracking during the hardening phase. Concrete curing will generate stresses if the motions caused by hydration are restrained. The two major reasons for these motions are ... -
Calculation and Visualization of Energy Dissipation and Energy Balance in Reservoir Models
(Master thesis, 2020)During the production lifetime of a hydrocarbon reservoir, various forms of energy are involved: external energy through wells, internal energy stored in the reservoir itself, and dissipated energy as heat released to the ... -
Calculation of acoustic wave velocities based on digital rock models
(Master thesis, 2021)Beregning av bølgehastigheter basert på μCT-bilder av bergarter kan gi verdifull kunnskap som kan brukes ved tolkning av seismisk data. For å sammenligne hastighetsresultatene fra en avlastet kjerneprøve med petrofysiske ... -
Calculation of Added Mass in the Proximity of the Seabed for an Oscillating Disc
(Master thesis, 2012)Calculations have been made with the commercial CFD-software Ansys Fluent, with dynamic mesh. -
Calculation of fatigue damage for tensioned risers from vortex induced vibrations
(Master thesis, 2011)Vortex induced vibration (VIV) of long flexible riser subjecting to ocean currents is ubiquitous in offshore industry. Although significant efforts have done to understand this complicated fluid structure interaction ... -
Calculation of interface curvatures with the level-set method for two-phase flow simulations and a second-order diffuse-domain method for elliptic problems in complex geometries
(Doktoravhandlinger ved NTNU, 1503-8181; 2013:214, Doctoral thesis, 2013)This thesis considers in the first part the mathematical modelling of incompressible two-phase flow, in particular the calculation of interface curvatures and normal vectors with the level-set method. The main contribution ... -
Calculation of NOx Formation in a Swirl Burner
(Master thesis, 2008)This thesis embraces simulations of NOx emissions from a partially premixed 20 kW swirl burner. The simulations were carried out in the commercial computational fluid dynamics software FLUENT. The concept of partial premixing ... -
Calculation of Particle Resuspension Using Static and Dynamic Particle Models
(Master thesis, 2011)The aim of this master work was to investigate particle resuspension from fouled heatexchanger surfaces. In metallurgical industries, the waste gas may contain dust and particles which can deposit on the heat exchanger ... -
Calculation of Service and Sea Margins
(Master thesis, 2015)In this thesis two tankers owned by Kristian Gerhard Jebsen Skipsrederi (KGJS) were investigated. A method of calculating service and sea margins for different speeds has been developed. When a ship is in normal operation, ... -
Calculation of the interface curvature and normal vector with the level-set method
(Journal article, 2013)This article addresses the use of the level-set method for capturing the interface between two fluids. One of the advantages of the level-set method is that the curvature and the normal vector of the interface can be readily ... -
Calculation of wave forces due to extreme events in the coastal region using REEF3D - Beregning av bølgebelastninger fra ekstrem vær i kyst områder med REEF3D
(Master thesis, 2018)The objective of this study is to validate that the Computational Fluid Dynamics (CFD) model REEF3D can capture the singularities of the structure-wave interaction in coastal regions. The two tasks established to achieve ... -

Calibration and development of a numerical method for frost protection
(Master thesis, 2019)Frost heave and spring thaw can be critical contributors to pavement deterioration in seasonal frost regions. Several numerical programs are available to predict frost penetration depth, but the lack of fixed material ... -
Calibration and uncertainty analysis of pressure sensors used for dynamic measurements
(Master thesis, 2017)Dynamic calibration of pressure sensors is challenging. Often, steady-state calibration is applied on pressure sensors used to measure dynamical measurements. Steady-state calibration does not represent the dynamic behavior ... -
