Review on reactor configurations for adsorption-based CO2 capture
(Peer reviewed; Journal article, 2021)Adsorption-based CO2 capture has enjoyed considerable research attention in recent years. Most of the research efforts focused on sorbent development to reduce the energy penalty. However, the use of suitable gas–solid ... -
Review on the Major Failure Cases of Unlined Pressure Shafts/Tunnels of Norwegian Hydropower Projects
(Journal article; Peer reviewed, 2016)The Norwegian hydropower industry has more than 100 years of experience in constructing the unlined pressure shafts and tunnels. Most of the hydropower projects have long waterway systems consisting unlined high pressure ... -
Review on the prevailing methods for the prediction of potential rock burst / rock spalling in tunnels
(Chapter, 2017)Rock burst / rock spalling is among the prevailing stability challenges, which can be met while tunneling through hard rock mass. Especially, this is very relevant for the mountainous country like Norway where hard rock ... -
A review on the properties of iron aluminide intermetallics
(Peer reviewed; Journal article, 2016)Iron aluminides have been among the most studied intermetallics since the 1930s, when their excellent oxidation resistance was first noticed. Their low cost of production, low density, high strength-to-weight ratios, good ... -
A Review on the Use of Self-Curing Agents and Its Mechanism in High-Performance Cementitious Materials
(Peer reviewed; Journal article, 2022)Self-cured concrete is a type of cement-based material that has the unique ability to mitigate the loss rate of water and increase the capacity of concrete to retain water compared to conventional concrete. The technique ... -
Review on Typical Marine Operations in Aquaculture and Numerical Simulation of One Example Operation Scenario
(Chapter, 2018)Aquaculture of Atlantic salmon in coastal and offshore locations is an operation intensive industry. This paper gives an overview of the most typical marine operations in the aquaculture of Atlantic salmon. Descriptions ... -
Review: PEMFC Materials' Thermal Conductivity and Influence on Internal Temperature Profiles
(Journal article; Peer reviewed, 2017)The polymer electrolyte membrane fuel cell (PEMFC) is far from isothermal when in operation. This is well established both from experiments and from mathematical modelling. Over the last 15 years, the research field and ... -
Reviewing the Achievement of Sustainable Production with a Focus on Maintenance
(Master thesis, 2022)Siden bærekraft har blitt mer viktig for produksjons firma, som Washington Mills, ville de ha en masteroppgave som ga en revisjon av deres vedlikehold. Hvor en link mellom bærekraftig produksjon og vedlikeholds optimalisering ... -
Reviewing the configuration of spare parts supply chains considering stock deployment and manufacturing options
(Doctoral theses at NTNU;2023:49, Doctoral thesis, 2023)Spare parts are strategic assets to ensure the execution of maintenance activities in industrial plants. They are exchangeable parts that can be used to replace damaged components, facilitating the restoration of the ... -
Reviewing the Learning Process through Creative Puzzle Solving
(Journal article; Peer reviewed, 2017)Human beings are at a continuous learning process at various levels and with different motivations during their whole lifetime. Puzzle solving may beneficially be applied to increase the motivation, enhance the mastering ... -
Reviewing the long-term sustainability of urban water systems rehabilitation strategies with an alternative approach
(Journal article; Peer reviewed, 2018)It is generally difficult to assess the performance of an infrastructure with a substantially longer life span than economic models can handle, and the life cycle concepts in urban water systems are normally limited to ... -
Reviewing the potential for including habitat fragmentation to improve life cycle impact assessments for land use impacts on biodiversity
(Peer reviewed; Journal article, 2019)Purpose The biosphere is progressively subjected to a variety of pressures resulting from anthropogenic activities. Habitat conversion, resulting from anthropogenic land use, is considered the dominant factor driving ... -
Reviewing the Potential of Phase Change Materials in Concrete Pavements for Anti-Freezing Capabilities and Urban Heat Island Mitigation
(Peer reviewed; Journal article, 2023)This study provides an overview of how phase change materials (PCMs) can improve the resistance of concrete pavement to freeze–thaw cycles and mitigate the urban heat island (UHI) effect. The investigation covers different ... -
