Investigations of the extended Eddy Dissipation Concept formulation for weakly turbulent and slow chemistry flames
(Peer reviewed; Journal article, 2023)Recent extensions of the Eddy Dissipation Concept (EDC) are investigated with the purpose of analysing the importance of model limiters to the EDC performance when predicting Moderate and Intense Low-oxygen Dilution (MILD) ... -
Investigations of the long-term extreme buffeting response of long-span bridges using importance sampling Monte Carlo simulations
(Peer reviewed; Journal article, 2022)Several studies have shown that site measurements of the buffeting responses of long-span bridges do not always agree with predictions from analytical models. The observed discrepancy is believed to be explained by the ... -
Investigations of unsteady pressure loading in a Francis turbine during variable-speed operation
(Journal article; Peer reviewed, 2017)Current study was aimed to investigate the unsteady pressure loading in a model Francis turbine under variable-speed configurations. Focus was to investigate the time-dependent characteristic frequencies and the pressure ... -
Investigations on mixture preparation for two phase adiabatic pressure drop of R134a flowing in 5 mm diameter channel
(Journal article; Peer reviewed, 2017)The article presents detailed two-phase adiabatic pressure drops data for refrigerant R134a. Study cases have been set for a mass flux varying from 200 to 400 kg/m2 s, at the saturation temperature of 19.4 ◦C. Obtained ... -
Investigations on Secondary Voltage Control for Long-Term Reactive Power Management
(Chapter, 2023)Voltage and reactive power management is a crucial task for system operators worldwide, and particularly in Norway. While manual operations within regional control cen-ters were once the norm, a major shift is currently ... -
Investigations on the feasibility of the CWE method to verify potential alkali release from aggregates in Norwegian field concrete
(Chapter, 2021)Concrete elements exposed for 26 years to seawater spray and deicing salts along a road close to Sandnessjøen in Norway were investigated. Concrete cores from 4 elements with different binder compositions (A: 100 % Portland ... -
Investigations on the Sustainable Resource Use of Swiss Timber
(Peer reviewed; Journal article, 2021)In Switzerland, the advantages of timber buildings for the climate are broadly discussed. In the following paper, a comparative sustainability assessment of four building alternatives is presented. Especially the contribution ... -

(Concept rapport;36, Book, 2013)The report provides a description of the Norwegian State Project Model, also referred to as the government’s scheme for external quality assurance of major public investment projects (the QA scheme). The scheme was introduced ... -
Investing in Your Alumni: Endowments’ Investment Choices in Private Equity
(Journal article; Peer reviewed, 2023)We investigate the role of alumni ties in university endowments’ decision to invest into private equity funds. Based on a sample of 1,590 commitments made by 189 U.S. endowments into 613 funds during the period of 1995 to ... -
Investment Decisions with Two-Factor Uncertainty
(Peer reviewed; Journal article, 2021)This paper considers investment problems in real options with non-homogeneous two-factor uncertainty. We derive some analytical properties of the resulting optimal stopping problem and present a finite difference algorithm ... -
Investment in electric energy storage under uncertainty: a real options approach
(Journal article; Peer reviewed, 2016)In this paper we develop a real options approach to evaluate the profitability of investing in a battery bank. The approach determines the optimal investment timing under conditions of uncertain future revenues and investment ... -
Investment in mutually exclusive transmission projects under policy uncertainty
(Journal article; Peer reviewed, 2016)In this paper we evaluate mutually exclusive transmission projects under policy and economic uncertainty. The alternatives being considered are transmission investment projects between Norway and Germany, and Norway and ... -
Investment in two alternative projects with multiple switches and the exit option
(Peer reviewed; Journal article, 2023)This paper uses an analytical framework to examine a firm’s investment and switching strategy under uncertainty. The context is the possibility to launch and operate two distinct projects, one at a time, with exposure to ... -
Investment Timing under Uncertain Renewable Energy Policy: An Empirical Study of Small Hydropower Projects
(Journal article; Peer reviewed, 2014-12-15)Policy uncertainty can be a powerful deterrent to immediate investments.} Based on panel data of 214 licenses to construct small run-of-the-river hydropower plants, we examine whether the prospect of a common Swedish-Norwegian ... -
