Sea ice conditions in relation to offshore wind development in the Southern Baltic Sea
(Master thesis, 2023)Dette arbeidet presenterer en analyse av isforholdene i Østersjøen. Den viktigste parameteren for å beskrive de lokale isforholdene er flatistykkelsen. Fra denne størrelsen kan andre isparamtre estimeres. Havisens termiske ... -
Searching for Sources of Ultra High Energy Cosmic Rays with a Clustering Analysis of arrival directions
(Master thesis, 2024)Ultra-høyenergiske kosmiske stråler (UHEKS) er partikler med energier over 10^18 eV, og antas å komme fra ekstragalaktiske kilder. Siden oppdagelsen av kosmiske stråler har man undret seg over hvordan disse partiklene ... -
Second order coherence of squeezed magnons in a thermal environment
(Master thesis, 2023)Spinbølger, eller magnoner, er interessante å studere på grunn av deres potensial som informasjonsbærende signaler i kondensert materie uten ohmisk tap, i motsetning til elektroner. Fenomenet kvantestramming er også et ... -
Seeing a Mycobacterium-Infected Cell in Nanoscale 3D: Correlative Imaging by Light Microscopy and FIB/SEM Tomography
(Journal article; Peer reviewed, 2015)Mycobacteria pose a threat to the world health today, with pathogenic and opportunistic bacteria causing tuberculosis and non-tuberculous disease in large parts of the population. Much is still unknown about the interplay ... -
Segmentation of the Cervical Spine based on 7T MRI
(Master thesis, 2023)Ultrahøyfelt-MR (UHF-MR), som 7T, har potensial til å forbedre bildekvaliteten i MR-undersøkelser gjennom økt oppløsning og forbedret signal-til-støy-forhold (SNR). Imidlertid introduserer UHF- MR også mer markante ... -
Selective area grown ZnTe nanowires as the basis for quasi-one-dimensional CdTe-HgTe multishell heterostructures
(Peer reviewed; Journal article, 2020)Selective area growth is employed in the vapor-liquid-solid molecular beam epitaxy of ZnTe nanowire arrays. Full control over the location of the individual nanowires is achieved by defined positioning of the growth catalyst. ... -
Selective area growth of AlGaN nanopyramid arrays on graphene by metal-organic vapor phase epitaxy
(Journal article; Peer reviewed, 2018)Wide-bandgap group III-nitride semiconductors are of special interest for applications in ultraviolet light emitting diodes, photodetectors, and lasers. However, epitaxial growth of high-quality III-nitride semiconductors ... -
Selective examination of optically and structurally separable parts within GaAs/AlGaAs core-shell nanowires by micro-photoluminescence and transmission electron microscopy
