Validation of QCL CF4 Gas Analyzer for Sensitivity and Selectivity
(The Minerals, Metals & Materials Series;2367-1181, Peer reviewed; Journal article, 2020)Quantum cascade lasers (QCL) has open the mid-infrared (mid-IR) spectral range for laser gas monitors. For perfluorocarbon gases (PFCs) such as CF4, continuous emission monitors are now commercially available. Since these ... -
Validation of temporal parameters within the skating sub-techniques when roller skiing on a treadmill, using inertial measurement units
(Peer reviewed; Journal article, 2022)The aim of this study was to develop and validate a method using inertial measurements units (IMUs) to determine inner-cycle parameters (e.g., cycle, poles and skis contact, and swing time) and the main sub-techniques ... -
Validity of the NTNU Prediction Model for D&B Tunnelling
(Peer reviewed; Journal article, 2023)The Norwegian University of Science and Technology (NTNU) has since the early 1970s published prediction models for estimated production rates, time consumption, and costs for rock works. Since the early development of the ... -

Value of green hydrogen when curtailed to provide grid balancing services
(Peer reviewed; Journal article, 2022)This paper evaluates the potential of grid services in France, Italy, Norway and Spain to provide an alternative income for electrolysers producing hydrogen from wind power. Grid services are simulated with each country's ... -
Value of multi-market trading for a hydropower producer
(Chapter, 2017)We present a case study for a price-taking hydropower producer trading in the three short-term energy markets, day-ahead, intra-day and the balancing market. The study uses a scheduling software with a detailed representation ... -
Value of Uncertainty: The Lost Opportunities in Large Projects
(Journal article; Peer reviewed, 2016)The uncertainty management theory has become well established over the last 20–30 years. However, the authors suggest that it does not fully address why opportunities often remain unexploited. Empirical studies show a ... -
Value Tensions in Telecare: An Explorative Case Study
(Chapter, 2018)We describe the results from a Norwegian case study of the attitudes of community-dwelling lung patients and health response center personnel toward a telecare service for such a patient group. The telecare service was ... -
Value-Creation Potential from Multi-Market Trading for a Hydropower Producer
(Journal article; Peer reviewed, 2018)We study a hydropower producer’s potential for value-creation from multi-market trading given the price variations in the markets and the flexibility provided through access to hydro reservoirs. We use a perfect foresight ... -

Vannkvalitetsproblemer og modellering av vannkvalitet i ledningsnett
(Journal article; Peer reviewed, 2012)I drikkevannsnettene oppstår vannkvalitetsproblemer som vekst av biofilm, korrosjon av støpejerns- og metallrør, samt misfarging av drikkevannet som fører til en stor andel av klager til vannselskapene [2]. Det er også en ... -
Vannskadesikker montering av vannrør i næringsbygninger
(SINTEF Fag;30, Research report, 2015)Forskrift om tekniske krav til byggverk (TEK10) stiller krav til utskiftbarhet og lekkasje-sikkerhet for ferdig monterte vanninstallasjoner i alle typer bygninger. Forskriften skiller ikke mellom bolig og næringsbygning. ... -
Vapor–liquid equilibria data for 2-piperidineethanol and 1-(2-hydroxyethyl)pyrrolidine in aqueous solutions and a UNIQUAC model representation
(Peer reviewed; Journal article, 2022)This work reports equilibrium data for two amines, 2-piperidineethanol (2-PPE) and 1-(2-hydroxyethyl)pyrrolidine (1-(2HE)PRLD), and their aqueous solutions. The pressure, temperature, and composition data are used to ... -
Vapour resistance of wind barrier tape: Laboratory measurements and hygrothermal performance implications
(Peer reviewed; Journal article, 2021)In the building industry, the interest into adhesive tape to achieve a more tight and robust building envelope has increased rapidly in recent years. With an increasing demand for energy efficiency in buildings, national ... -
Vapour retarders in wood frame walls and their effect on the drying capability
(Journal article; Peer reviewed, 2013)Wood frame walls typically need a vapour barrier at the warm side to avoid interstitial condensation due to vapour diffusion and air leakages from the interior. A more vapour open material than the traditional vapour ... -
Variability in the formation and framework polymorphism of metal-organic frameworks based on yttrium(III) and the bifunctional organic linker 2,5-dihydroxyterephthalic acid
(Peer reviewed; Journal article, 2020)Depending on the solvothermal reaction conditions, we obtained three different metal‐organic frameworks with yttrium(III) as metal component and 2,5‐dihdyroxyterepthalic acid (H4dhtp) as bifunctional organic linker: ... -
