CFD-Model for the Photothermal Conversion Process in Ionic Nanofluids
(Master thesis, 2018-06-20)Harnessing energy from a sustainable source like the Sun may be one of the key solutions for the increasing demand of energy. However, conventional solar harvesters are relatively low efficient so that use of solar energy ... -
Challenges related to storage and transfer of solar energy with a case study on long distance power transfer
(Master thesis, 2010-06-21)The challenges that will be discussed in this thesis are two-fold; the problems related to trans- mission of power over long distances, and the need for energy storage, especially at night. Both of the issues are accentuated ... -
Characterisation of a Digital Sampling Calorimeter Prototype for Proton Computed Tomography With Electron Beams
(Master thesis, 2020-12-19)Proton CT is a novel imaging modality designed to improve dose planning and treatment monitoring in proton therapy. The precision of the beam of charged particles, like protons, requires accurate diagnostics, to avoid ... -
Characterization and finite element modelling of piezoelectric ceramic discs vibrating in air, for a frequency range including the first two radial modes.
(Master thesis, 2021-08-13)The objectives of this work is to measure and characterize the electrical and acoustical behaviours of a piezoelectric ceramic disk of type Pz27, across a frequency spectrum covering the first two radial modes, and to ... -
Characterization of a neutral helium beam for helium microscopy
(Master thesis, 2015-06-29)Neutral helium beam microscopy is a new development in scientific instrumentation where neutral helium atoms are utilized to image a sample. The main advantage of using neutral helium is the significantly smaller energy ... -
Characterization of Hyper Spectral Irradiance and Radiance Sensors
(Master thesis, 2013-09-11)It is surprisingly problematic to to accurately measure light in the laboratory. Even more so when measuring in the field. There are lots of areas where measuring light spectrum and irradiance outside a laboratory is of ... -
Characterization of Silicon Photomultiplier and Design of Front-End Electronics for ALOFT
(Master thesis, 2022-06-01)ALOFT is an aircraft campaign led by Birkeland Centre for Space Science at University of Bergen. The primary goal of the campaign is to look for Terrestrial Gamma Ray Flashes and gamma-ray glows, both high-energetic phenomena ... -
Characterization of the ALPIDE chip with Helium-4 ions for Proton Computed Tomography
(Master thesis, 2018-12-06)Particle therapy has become an appealing therapeutic option for patients with various tumor types. The physical properties of charged particles allow for an improved dose distribution conformality compared to conventional ... -
Characterization of the ALPIDE Detector with Proton Beams for the Development of a Prototype Computed Tomography Machine at the University of Bergen
(Master thesis, 2018-07-04)In conventional radio therapy, photons is used in the treatment. Treatment with protons, however, greatly reduce the energy which is deposited in healthy tissue surrounding the tumor. The aim for the pCT group at the ... -
