Comparison of trihalomethanes in the air of two Indoor swimming pool facilities using different type of chlorination and different types of water
(Journal article, 2017)Certain aspects of the distribution of disinfection by-products (DBPs) in the air of indoor swimming pools, the exposure of the users, and possible health effects, have not been well documented. To determine the distribution ... -
Comparison of two hydrodynamic models for their rain-on-grid technique to simulate flash floods in steep catchment
(Journal article; Peer reviewed, 2024)In this study, two hydrodynamic models, TELEMAC-2D and HEC-RAS 2D, were compared for their Rain-on-Grid (RoG) technique with a particular focus on runoff generation processes in a small and steep catchment. Curve number ... -
A comparison of two seawater adaptation strategies for Atlantic salmon post-smolt (Salmo salar) grown in recirculating aquaculture systems (RAS): Nitrification, water and gut microbiota, and performance of fish
(Peer reviewed; Journal article, 2021)The land-based production phase in Norwegian Atlantic salmon farming has the past years been extended to include post-smolt for an increasing number of farmers. Post-smolt production can involve introduction of brackish/seawater ... -
A Competency Model for the Selection and Performance Improvement of Project Managers in Collaborative Construction Projects: Behavioral Studies in Norway and Finland.
(Peer reviewed; Journal article, 2020)Collaborative work practices are getting more common in construction projects. Consequently, new project delivery models have emerged and new practices have also entered the world of traditional delivery models. The resultant ... -
Competitive Dialogue in Norwegian Public Infrastructure Projects
(Journal article; Peer reviewed, 2018)Competitive dialogue (CD) is a relatively new procurement procedure introduced in 2004 by the European Parliament for particularly complex contracts. The Norwegian Public Roads Administration (NPRA) has limited experience ... -
Competitive Dialogue – experiences with the award criteria
(Journal article; Peer reviewed, 2018)The Competitive Dialogue (CD) is a procurement procedure that was introduced in Norway in 2007. The procedure enables the client to have a dialogue phase with pre-qualified contractors before awarding the contract. When ... -
Competitiveness of train and airport express bus between the city of Trondheim and Trondheim Airport, Værnes
(Master thesis, 2016)In order to develop a better transportation corridor between city of Trondheim and town of Steinkjer in Sør-Trøndelag county, Norway a number of infrastructure investments are going to be made. Among them a double track ... -
Complex eigenvalue analysis and parameters analysis to investigate the formation of railhead corrugation in sharp curves
(Peer reviewed; Journal article, 2020)Rail corrugation, a quasi-sinusoidal irregularity of the rail head, is a common issue experienced throughout the railway networks worldwide. It generally leads to high wheel-rail dynamic loads, increased noise emission, ... -
Complex geometry handling for a cartesian grid based solver
(Chapter, 2017)Complex geometries can be a challenge for computational fluid dynamics (CFD) solvers that use a Cartesian mesh. In the current paper, an algorithm is described with which complex geometry features can be incorporated in a ... -
Composite breakwater with circular caissons
(Master thesis, 2010)A new breakwater design, consisting of a high rubble foundation with concrete cylinders in two rows placed on tophas been proposed for an extensive port development project.In this report, different types of breakwaters ... -
Compression and swelling of cohesionless soils with organic content
(Master thesis, 2023)Nesten 9% av Norge er dekket av torvmaterialer. Antallet ingeniørprosjekter innenfor områder med torv er økende ettersom ressursutvikling og infrastrukturutbygging fortsetter å vokse i Norge. Å forutsi setninger og ... -
