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 ice accumulation on Coanda Screen intakes
(Chapter, 2020)Coanda screen intakes has proved to be a reliable and cost-effective low maintenance solution for numerous small hydro (SHP) intakes in the past two decades. In Norway 50 intakes are installed since 2012, the first intake ... -
Reducing the number of load cases for fatigue damage assessment of offshore wind turbine support structures using a simple severity-based sampling method
(Journal article; Peer reviewed, 2018)The large amount of computational effort required for a full fatigue assessment of offshore wind turbine support structures under operational conditions can make these analyses prohibitive, especially for applications like ... -
Reducing Urban Water System's Carbon Footprint and Reservoir Water Balance Study in Ceuta, Spain
(Master thesis, 2016)This study seeks to reduce the energy consumed by the water company in Ceuta by implementing two type of developments: hydropower and solar photovoltaic project. It will be necessary to design both schemes and determine ... -
Reduction lists as tool for cost control in public building projects
(Journal article, 2016)Purpose: The purpose of this paper is to study the use of potential scope reductions in major construction projects for special-purpose buildings. Scope reductions may result in buildings that are less fit for purpose; ... -
Reduction of the wave propagation error of a sigma grid based numerical tank using a vertical spacing based on the constant truncation error
(Peer reviewed; Journal article, 2021)Numerical wave models that solve the Laplace equation for the velocity potential with a -grid in the vertical direction have been proven to be flexible and efficient. However, it is observed that the dispersion relation ... -
Reduksjon av klimaavtrykk fra entreprenørselskaper
(Bachelor thesis, 2021)Som følge av EU og Norges kommende krav og målsettinger for CO2-utslipp, er denne oppgaven utviklet for å belyse områdene innen anleggsvirksomhet med det største potensialet for reduksjon, sett fra entreprenørens synsvinkel. ... -
Reduksjon av klimagassutslipp fra massivtrekonstruksjoner
(Bachelor thesis, 2022)Bruk av bærekonstruksjon i tre er å foretrekke før stål og betong med tanke på å redusere klimafotavtrykket til bygninger. Bygninger der krysslaminerte treelementer (massivtre) utgjør komponenter som vegger, tak og ... -
Reduksjon av konfliktpunkter i plan- og toplanskryss
(Master thesis, 2022)I Norge gjennomføres en betydelig andel av alle reiser med personbil. Det er store samfunnsøkonomiske kostnader knyttet til både reisetid, køkjøring og ulykker i biltrafikken. Et effektivt og sikkert transportsystem som ... -
Reduksjon av sløsing i produksjon på byggeplass
(Master thesis, 2016)Høye byggekostnader og lav produktivitet er to av byggenæringens største utfordringer. Det er et ønske i næringen om at produktiviteten skal forbedres og kostnadene skal reduseres. Reduksjon av sløsingen i produksjon antas ... -
REDWIN – REDucing cost in offshore WINd by integrated structural and geotechnical design
(Journal article; Peer reviewed, 2018)The cost of offshore wind energy production has to be reduced continuously to improve its competitiveness compared to other energy sources. To contribute to this goal, a 4- year research project REDWIN – REDucing cost of ... -
