Reducing fuel consumption and emissions through optimization of the vertical alignment of a road: A case study of a heavy-duty truck on the Norwegian Highway Route E39
(Peer reviewed; Journal article, 2019)In this paper, a method to assess, optimize and modify the vertical alignment of a road is developed. The aim is to optimize the alignment with respect to fuel consumption and quantify the induced reduction in terms of ... -
Reducing the exergy destruction in the cryogenic heat exchangers of hydrogen liquefaction processes
(Journal article; Peer reviewed, 2018)A present key barrier for implementing large-scale hydrogen liquefaction plants is their high power consumption. The cryogenic heat exchangers are responsible for a significant part of the exergy destruction in these plants ... -
Reducing the risk of viral contamination during the coronavirus pandemic by using a protective curtain in the operating room
(Peer reviewed; Journal article, 2022)Background Airborne transmission diseases can transfer long and short distances via sneezing, coughing, and breathing. These airborne repertory particles can convert to aerosol particles and travel with airflow. During ... -
Reduction of CO2 Emissions in the Salmon Farming Industry: The Potential for Energy Efficiency Measures and Electrification
(Master thesis, 2019)Elektrisk kraftforsyning til oppdrettsanlegg for laks dekkes i dag av dieselaggregater eller ved tilkobling til landstrøm. Det er ønskelig å øke andelen av oppdrettslokaliteter koblet på landstrøm for å redusere ... -
Reduction of NOx Emissions from the Gas Turbines for Skarv Idun
(Master thesis, 2007)Nitrogen oxides (NOx) are formed by oxidation of nitrogen during the combustion process, and production rate is highly affected by flame temperature. NOx is regarded as a local pollutant causing smog, acid rain and health ... -
