Use of biodegradable colloids and carbon black nanofluids for solar energy applications
(Journal article; Peer reviewed, 2021)The conversion of solar energy to heat can be performed in direct absorption solar collectors, where the radiation from the sun is absorbed by a fluid. There are various types of fluids that can be used, and recently, ... -
Use of CO2 Foam to Increase CO2 Storage and Oil Recovery for CCUS
(Master thesis, 2022-06-10) -
Use of market ready light dosimeters for patients with erythropoietic protoporphyria disorder
(Master thesis, 2017-06-21)Erythropoietic protoporphyria (EPP) disorder causes severe pain in the skin when patients are overexposed to light, particularly blue light. These patients can only stay exposed to sunlight for a short amount of time, and ... -
Using machine learning to characterize solar wind driving of convection in the terrestrial magnetotail lobes
(Journal article; Peer reviewed, 2023)In order to quantitatively investigate the mechanism of how magnetospheric convection is driven in the region of magnetotail lobes on a global scale, we analyzed data from the ARTEMIS spacecraft in the deep tail and data ... -
Using Multivariate Data Analysis and ATR-FTIR Spectroscopy for Modeling Components Present During CO2 Capture with Amines
(Master thesis, 2018-06-20)This master thesis is a collaboration between Technology Centre Mongstad (TCM) and University of Bergen. The project is to develop a method to accurately predict total inorganic carbon, total alkalinity and density using ... -
Utvikling av kjennetegn på elevers måloppnåelse innen kritisk tenkning i naturfag
(Master thesis, 2020-12-20)Fagfornyelsen har et fokus på kritisk tenkning (Kunnskapsdepartementet, 2017). I den sammenheng ønsker jeg å utvikle et verktøy til kritisk tenkning som både elever og lærere kan ta i bruk. Jeg har utviklet kjennetegn på ... -
UV and aerosol climatology based on simulations and measurements by satellites and ground station
(Doctoral thesis, 2013-03-22)Solar radiation (200–4,000 nm) is very important for the climate system on Earth. It provides heat and drives the photosynthesis in plants to fuel all life. It plays a major role in the original synthesis of biomolecules ... -
Validating the Space Weather Modeling Framework (SWMF) for applications in northern Europe: Ground magnetic perturbation validation
(Journal article; Peer reviewed, 2020)In this study we investigate the performance of the University of Michigan’s Space Weather Modeling Framework (SWMF) in prediction of ground magnetic perturbations (ΔB) and their rate of change with time (dB/dt), which is ... -
Validation of Soot Modelling in the CFD code FLACS
(Master thesis, 2019-06-19)In a fire scenario, the role of soot is important from different standpoints. It has a significant contribution to heat transfer by radiation and it proves to be a hindrance in evacuation activities as it reduces visibility. ... -
Vannbasert eor i oppsprukne bergarter - økt oljeutvinning ved kjemikalietilsetning i injeksjonsvannet
(Master thesis, 2010-06-01)En stor del av verdens hydrokarbonreserver finnes i karbonater. Karbonatreservoarer er komplekse fordi reservoarbergarten ofte er sprø og sprekker lett. Mineralsammensetningen av karbonater gjør poreoverflaten mer tilbøyelig ... -
Vanninjektivitet og svekking av kalk under injeksjon av kaldt vann
(Master thesis, 2014-12-05)Primær oljeutvinning ved trykkavlastning gir ofte lav utvinningsgrad, og etterlater stor restoljemetning i reservoaret. For å forbedre oljeutvinningsgraden kan andre produksjonsmetoder benyttes; vanninjeksjon har i lang ... -
Vannutfelling på rustoverflater i gassrør
(Master thesis, 2009-06-12)Målet for denne oppgaven har vært å legge et grunnlag for beregninger av vannegenskaper i adsorbert fase på rust. Egenskaper bestemmes av et antall kompliserte termodynamiske og kinetiske mekanismer, som gjør at problemstillingen ... -
Variation in relative biological effectiveness for cognitive structures in proton therapy of pediatric brain tumors
(Journal article; Peer reviewed, 2021)Background Clinically, a constant value of 1.1 is used for the relative biological effectiveness (RBE) of protons, whereas in vitro the RBE has been shown to vary depending on physical dose, tissue type, and linear energy ... -
Variation of bending rigidity with material density: bilayer silica with nanoscale holes
(Journal article; Peer reviewed, 2022)Two dimensional (2D) materials are a young class of materials that is foreseen to play an important role as building blocks in a range of applications, e.g. flexible electronics. For such applications, mechanical properties ... -
Vector meson photoproduction in UPCs with FoCal
(Journal article; Peer reviewed, 2023)We discuss the physics prospects of photon-induced measurements using the high-granularity FoCal detector to be installed at the ALICE experiment, covering the pseudorapidity interval 3.4 ≤ η ≤ 5.8. This new detector, ... -
