Doped ZnS Thin Films for Intermediate Band Solar Cells - Deposition and Characterization
(Master thesis, 2015)Intermediate band solar cells (IBSCs) has the potential of increasing the efficiency and reducing the cost of commercial solar cells. The realization of such cells relies on the development of intermediate band (IB) ... -
Dose surface maps as a tool to predict toxicity after radiotherapy for cervical cancer patients
(Master thesis, 2017)Cervical cancer is one of the leading cancer types for women, both in incidence and mortality. The standard treatment for cervical cancer is brachytherapy and external beam radiotherapy in combination with chemotherapy. ... -
Dosedekning til uterus i pasienter med cervix cancer som gjennomgår ekstern stråleterapi: VMAT vs. 4 felts boksteknikk
(Master thesis, 2013)Formålet med denne oppgaven var å undersøke den interfraksjonelle organbevegelsenav øvre del av uterus i pasienter med intakt uterus som gjennomgår eksternstråleterapi som en del av den kurative behandlingen mot cervix ... -
Dosimetric impact of geometric distortions in radiotherapeutic dose planning
(Master thesis, 2022)Bakgrunn: Magnetisk resonanstomografi (MR) har potensial til å forbedre strålebehandling ved å forbedre volum inntegning, fjerne usikkerhet knyttet til bildesamregistrering og tilføye funksjonell vevs-informasjon. I klinisk ... -
Dosimetric Predictors of Toxicity in Prostate Cancer Radiotherapy - From Per-Organ to Per-Voxel Analysis
(Master thesis, 2021)Bakgrunn: Bedre strålebehandling mot prostatakreft gjør at overlevelsesraten øker. Dette fører til at flere pasienter lever lenger med bivirkninger som potensielt kan redusere livskvalitet (QoL). Nye og forbedrede metoder ... -
Dosimetry and evaluation of algorithm for inverseoptimized doseplanning for brachytherapy
(Master thesis, 2009)Purpose Individual optimized treatment planning is recommended when creating treatment plans for brachytherapy of cervical cancer. Manual alteration of the dose distribution is time consuming and the treatment plan may ... -
Drag and Phases in Interacting and Spin-Orbit Coupled Superfluid Bose-Einstein Condensates
(Master thesis, 2018)Motivated by previous work on drag effects in superfluid Bose-Einstein condensates, the Bose-Hubbard model on the square lattice is considered using mean-field theory, and a method for computing the superfluid drag density ... -
Drivers of the high frequency variability of gravity wave forcing in the mesosphere and lower thermosphere
(Master thesis, 2015)In this thesis the influence of gravity waves (GWs) in the mesosphere/lower thermosphere (MLT) was analysed. This was inspired by the work done in the paper by de Wit et al. (2014), which used the SKiYMET meteor radar in ... -
Drop-on-demand i presisjonsjordbruk
(Master thesis, 2013)Denne oppgaven beskriver et eksperiment der vi har skutt dråper gjennom luft med hastighet 4 m/s pluss/minus 10%. Hensikten var å skyte dråper så langt som mulig med definert presisjon og uten oppbrytning ved å justere 3 ... -
DScribe: Library of descriptors for machine learning in materials science
(Journal article; Peer reviewed, 2019)DScribe is a software package for machine learning that provides popular feature transformations (“descriptors”) for atomistic materials simulations. DScribe accelerates the application of machine learning for atomistic ... -
Dynamic contrast-enhanced MRI in head and neck cancer: a systematic comparison of different modelling approaches
(Master thesis, 2022)Bakgrunn Kreftsvulster er karakterisert av uorganisert blodkarnettverk på grunn av økt angiogenese, som vil si formasjon av blodårer. Dette resulterer i at svulsten får områder med lavt oksygennivå, kalt hypoksi. Hypoksi ... -

Dynamic Light Scattering Based Microrheology of End-Functionalised Triblock Copolymer Solutions
(Peer reviewed; Journal article, 2023)Nano-sized particles functionalised with short single-stranded (ss)DNAs can act as detectors of complementary DNA strands. Here we consider tri-block-copolymer-based, self-assembling DNA-coated nanoparticles. The copolymers ... -
Dynamic Micro-CT utilising Golden Ratio Sampling and Three-dimensional Generative Adversarial Networks
(Master thesis, 2023)Temporal datatomografi, dynamisk datatomografi, eller bare 4D-CT, er en røntgenavbildningsteknikk hvor tredimensjonale dynamiske prosesser kan avbildes. Ulempen med CT er de mange projeksjonene som kreves for å rekonstruere ... -
