Evaluation of Power Losses and Ruggedness of SiC MOSFETs for use in High-Power High-Frequency Induction Heating Generators
(Master thesis, 2018)As the Si IGBTs are confronting its physical limitations when it comes to high-frequency high-power applications, the SiC MOSFET sails up as a promising substitute due to its material properties. However, in the process ... -
Evaluation of Powerhouse Cavern for the SachKhas Hydroelectric Project in Himachal, India
(Journal article; Peer reviewed, 2017)Evaluation of an underground powerhouse cavern’s stability is a challenging task and needs to be carried out carefully by taking care of its location, orientation and dimensioning. This article deals with the stability ... -
Evaluation of pre-diagnostic blood protein measurements for predicting survival after lung cancer diagnosis
(Peer reviewed; Journal article, 2023)Background To evaluate whether circulating proteins are associated with survival after lung cancer diagnosis, and whether they can improve prediction of prognosis. Methods We measured up to 1159 proteins in blood ... -
Evaluation of precipitation distribution over Nepal using satellite data and its applications in Hydrological Modelling
(Master thesis, 2011)Precipitation is a vital element of an atmosphere that has direct effect on Hydrology. Therefore, an accurate estimation of precipitation is obligatory to predict runoff through the catchment. Nepal has a high spatial ... -
Evaluation of predictive methods for wind turbine performance and wake development
(Master thesis, 2014)In this project I have predicted the performance and the wake development for a model wind turbine using the actuator disc with Blade Elements Momentum (BEM) methods. The flow has been solved using OpenFOAM, an open-source ... -
Evaluation of Price Forecasts for Hydropower Expansion Planning Applications
(Master thesis, 2008)This Master Thesis deals with the importance of forecasting as exact power prices as possible for use in expansion planning. The work is a continuation of the Project Thesis finalized in December 2007 (Lind & Eggerud, ... -
Evaluation of Probabilistic Project Cost Estimates
(Journal article; Peer reviewed, 2021)Evaluation of cost estimates should be fair and give incentives for accuracy. These goals, we argue, are challenged by a lack of precision in what is meant by a cost estimate and the use of evaluation measures that do not ... -
Evaluation of Process Cooling in Subsea Separation, Boosting and Injection Systems (SSBI)
(Master thesis, 2012)The next generation of subsea process systems will combine the subsea gas compression technology currently under qualification with the previously developed subsea processing technologies, including separation, multiphase ... -
Evaluation of Process- and Input-Output-Based Inventories for Environmental Assessment of Production and Consumption Activities: Evaluering av prosess- og kryssløpsbaserte inventardata for miljøanalyser av våre produksjons og konsum aktiviteter
(Master thesis, 2010)Life cycle assessment (LCA) and environmentally extended input-output analysis (IO) both make it possible to account for the direct and indirect environmental impacts of whole life cycles of commodities and services. While ... -
Evaluation of processes for subsea dehydration and glycol regeneration
(Master thesis, 2016)The worlds remaining oil and gas resources are often found at vast sea depths and locations with harsh weather. This has created an incentive for developing subsea technology, enabling production and processing at the ... -
Evaluation of Production Enhancement Alternatives for the Morvin Field
(Master thesis, 2016)Fields producing by pure depletion face challenges due to the low reservoir pressure after some years of production. This pressure is insufficient for fluid to flow at a desired rate from the reservoir up to the surface ... -
