Modelling of Brainstem Toxicity Including Variable Relative Biological Effectiveness in Paediatric Proton Therapy
(Master thesis, 2021-06-01)Brainstem necrosis is a rare but severe side-effect following paediatric proton therapy. Substructures of the brainstem may be associated with regional differences in radiosensitivity, but these are not accounted for ... -
Modelling of multiphase flow through a subsea recirculation line equipped with a choke
(Master thesis, 2023-02-23)A peculiar problem encountered in engineering practices for multiphase flows is the pressure loss in piping systems. Because of the variations in viscosities, densities, and velocities of the fluid phases, multiphase systems ... -
Models for the relative biological effectiveness in proton therapy: on the impact of cell-irradiation design
(Master thesis, 2020-07-07)Background: The use of protons was first suggested for use in treating cancer in 1946, due to its preferable dose distribution. In clinical practice, a constant Relative Biological Effectiveness (RBE) of 1.1 is used in ... -
Monte Carlo simulations of neutron based in-vivo range verification in proton therapy – optimization of detector dimensions and positioning
(Master thesis, 2019-12-06)Proton therapy is a cancer treatment modality expanding in clinical applications around the world. Due to the finite range of a monoenergetic proton beam, it is possible to spare more of the healthy tissue surrounding the ... -
Monte Carlo Simulations of Occupational Radiation Exposure During X-ray Guided Interventional Cardiology Procedures
(Master thesis, 2021-03-05)X-ray imaging is widely used as a diagnostic tool in many medical fields. Medical personnel can often reduce their exposure with distance and sufficient radiation protection, as they do not have to be close to the radiation ... -
MRI compatible miniature motor system: Proof of Concept
(Master thesis, 2019-12-19) -
Multi Pulse Terrestrial Gamma-ray Flashes and optical pulses of lightning observed by ASIM
(Master thesis, 2023-06-02)This thesis presents 52 multi pulse Terrestrial Gamma-ray Flashes (TGFs) identified from The Atmosphere-Space Interactions Monitor (ASIM) since launch until the end of 2022. -
Multidisciplinary Moorings in the Arctic and Coastal Areas
(Master thesis, 2022-06-15) -
Multivariat analyse av CO2-absorbsjon ved bruk av ulike aminblandingsforhold
(Master thesis, 2019-06-26)Denne masteroppgaven er en samarbeidsoppgave mellom Universitet i Bergen og Technology Centre Mongstad (TCM). Hensikten med masteroppgaven er å opparbeide kunnskap til en metode som kan separere CO2 fra det fossile avfallet, ... -
Neutrino Magnetic Moments in the Standard Model and Beyond
(Master thesis, 2022-06-01)This thesis presents the theory describing the magnetic moments of Dirac and Majorana neutrinos, including a systematic method for extracting the neutrino magnetic moments from a given theory using electromagnetic form ... -
Neutrino-Antineutrino Oscillations
(Master thesis, 2023-06-07)Oppgaven presenterer teorien bak massive nøytrinoer. Vi viser hvordan nøytrino masse og miksing leder til nøytrino oscillasjoner. Flere konsekvenser av slike oscillasjoner blir diskutert. Etter introduksjonen av en Majorana ... -
Normal Incidence Ultrasonic Beam Transmission Through Steel Plates. Measuring and Modelling The Transmission Coefficient
(Master thesis, 2020-06-30)Ultrasonic beam transmission through solid plates has been extensively studied overthe past decades. Through this study many anomalies have been found, that plane-wave theory can not account for. It is therefore important ... -
Normally incident ultrasonic beam transmission through a water-embedded steel plate as a function of ka-number
(Master thesis, 2023-06-01) -
Numerical Modeling of a CO2 Foam EOR and CO2 Storage Field Pilot.
