A comparison of life history and biological characters between Atlantic salmon first-time and repeat spawners in two Norwegian rivers
(Master thesis, 2023)Iteroparitet er en avveiningsstrategi mellom nåværende og fremtidig reproduksjon. Risikoen for svikt i reproduksjonen er spredt over tid dersom fisken kan overleve sin første gyting og gyte igjen på et senere tidspunkt. ... -
A comparison of machine learning algorithms to investigate methylation profiles and predict type 1 diabetes
(Master thesis, 2021)Forekomsten og utbredelsen av type 1 diabetes i verden har økt de siste fire tiårene. Rakyan et al. hadde en hypotese om at noen av de ikke-genetiske faktorene skyldtes epigenetisk variasjon. Målet med denne masteroppgaven ... -
A comparison of two parallel solution schemes for the advection-diffusion equation - Velocity guided random walk of paticles vs finite volume discretization on Cartesian grid
(Master thesis, 2017)In this thesis two methods for solving the diffusion-advection equation was implemented using MPI. The two methods was a velocity guided random walk of particles and solving the advection-diffusion equation on a grid. Both ... -
A comprehensive mitogenome phylogeny of the avian tribe Arini (Arinae: Psittacidae) with emphasis in Pyrrhura species
(Master thesis, 2021)The tribe Arini is the most diverse group of Neotropical parrots, and it includes approximately 158 species distributed in at least 32 genera. These parrots have been largely affected by habitat loss, fragmentation, and ... -
A computational study of a ionic liquid and its ability to dissolve cellulose
(Master thesis, 2022)Oppløsningsmekanismen til en cellulosebunt solvatisert i blandinger av vann, Na+ og OH ble analysert gjennom molekylær dynamikksimulering og sammenlignet med den første i sitt slag simulerte ionisk væske som løsningsmiddel. ... -
A CRISPR/Cas13-based method for downregulation of ALB3 genes in Phaeodactylum tricornutum
(Master thesis, 2021)Diatoms, a group of unicellular photosynthetic microalgae, are of high ecological importance. They are responsible for about 20% of the world’s oxygen production. They have also been exploited in research due to their high ... -
A CUDA Back-End for the Equelle Compiler.
(Master thesis, 2014)As parallel and heterogeneous computing becomes more and more a necessity for implementing high performance simulators, it becomes increasingly harder for scientists and engineers without experience in high performance ... -
A Density Functional Theory Study of Hydrogen Transfer and Rotational Barriers in Vitamin E-like Molecules
(Master thesis, 2011)A study of the antioxidant property of two vitamin E simplifications with density functional theory has been done. In one of the simplifications the phytyl tail and the methyl group on the heterocyclic ring in vitamin E ... -
A Diet Rich in Carbohydrates Induces Changes in Serum microRNA Levels Associated with Type 2 Diabetes Development.
(Master thesis, 2012)It is known that the level of serum microRNAs, small RNA molecules involved in regulation of gene expression, is altered in diabetic patients compared to healthy individuals and that microRNAs may be involved in the ... -
A dynamic state modelling approach to partial migration in brown trout
(Master thesis, 2022)Partiell migrasjon, fenomenet der ein populasjon har både individ som migrerer og individ som let vere, er observert i store delar av dyreriket. Mekanismane bak kan vere komplekse, og kan inkludere både genetikk og miljø ... -
A Fast Simulation Method for Ultrasonic Wave Propagation in Coupled Non-parallel Plates
(Master thesis, 2021)Enkelte systemer i ultralydtesting kan tilnærmes som to ikke-parallelle plater koblet med et fluid, der utstrålende Lamb-bølger brer seg ut i hver plate. Denne oppgaven utvikler en rask og nøyaktig simuleringsmetode for ... -
A faunistic assessment of species diversity in the class Ascidiacea in Norwegian waters using morphological and molecular analyses, including three case studies of the genera Ascidiella Roule, 1884, Botryllus Gaertner, 1774, and Botrylloides Milne Edwards, 1841
(Master thesis, 2023)I moderne systematikk brukes en integrativ tilnærming for artsavgrensning, hvor morfologiske og molekylære metoder ofte kombineres. Ett av målene med DNA-strekkoding er å bygge en plattform for identifisering av dyrearter, ... -
A field theoretical study of particles in an external magnetic field Setting up the foundations to study QCD in a strong magnetic field
(Master thesis, 2021)I denne master oppgaven studerer vi forskjellige typer partikler i et konstant magnetisk felt. Grunnen til det er for å få et grunnleggende forståelse og skape fundamentale verktøy til å undersøke QCD i sterke magnetiske ... -
A Finite-Size Study on Samarium-Substituted Bismuth Ferrite: Multiferroic and Lead-Free Piezoelectric Materials
(Master thesis, 2011)Multiferroic materials combine two or more ferroic orders such as ferroelectricity, ferromagnetism and ferroelasticity. They have a great interest for the development of the next generations of digital electronic memory ... -
A first-principles Study of epitaxial Interfaces between Graphene and GaAs
(Master thesis, 2014)Epitaxial interfaces between graphene and GaAs(111) have been investigated through a first-principles study using density functional theory (DFT). The GaAs(111) surface at the interface is assumed to be 2x2 reconstructed ... -
