Optimizing hydroxyl airglow retrievals from long-slit astronomical spectroscopic observations
(Peer reviewed; Journal article, 2017-08-25)Astronomical spectroscopic observations from ground-based telescopes contain background emission lines from the terrestrial atmosphere's airglow. In the near infrared, this background is composed mainly of emission from ... -
Optimizing maintenance plans of offshore wind farms by calculating the likelihood of future turbine failures
(Master thesis, 2022-06-01)Although offshore wind power shows promising energy potentials, high cost of operating and maintaining offshore wind farms concerns investors. Different maintenance strategies are applied by wind farm operators to overcome ... -
Optimizing marine insurance brokerage
(Master thesis, 2019-06-26)Insurance coverages for marine shipping fleets are often created by a broker, who negotiates underwriter insurance offers on behalf of the fleet owner. The broker evaluates different combinations of offers, searching for ... -
Optimizing storage of fish feed – An experimental study on maximizing the available space at Skretting's storage facility.
(Master thesis, 2021-10-17)In this Master's thesis I develop a mixed integer linear programming (MILP) optimization model. The model is designed to propose storage placements for upcoming production of fish feed. -
Optimizing the Liquid Target Production of the PET-radionuclide Ti-45 from a Natural Scandium Target
(Master thesis, 2022-09-15)The search for novel PET-nuclides is an ongoing process as some applications require decay characteristics that are different from the conventional ones. The use of novel radionuclides will fill the gap between conventional ... -
Optimum power control of a battery energy storage system

Optisk goniometer for optimalisering av retningsbestemt solenergi
(Master thesis, 2017-06-13)Det er et økende fokus på fornybar energi og bærekraftig matproduksjon, det vil derfor være nyttig med teknologi som kan føre til økt effektivitet i produksjon av dette. Utnyttelse av solenergi er et felt som er mye brukt, ... -
Order Reconfiguration Under Width Constraints
(Journal article; Peer reviewed, 2021)In this work, we consider the following order reconfiguration problem: Given a graph G together with linear orders ω and ω' of the vertices of G, can one transform ω into ω' by a sequence of swaps of adjacent elements in ... -
Order Reconfiguration under Width Constraints
(Journal article; Peer reviewed, 2023)In this work, we consider the following order reconfiguration problem: Given a graph G together with linear orders ω and ω′ of the vertices of G, can one transform ω into ω′ by a sequence of swaps of adjacent elements in ... -
Order-Related Problems Parameterized by Width
(Doctoral thesis, 2022-05-25)In the main body of this thesis, we study two different order theoretic problems. The first problem, called Completion of an Ordering, asks to extend a given finite partial order to a complete linear order while respecting ... -
ORFik: a comprehensive R toolkit for the analysis of translation
(Journal article; Peer reviewed, 2021)Background With the rapid growth in the use of high-throughput methods for characterizing translation and the continued expansion of multi-omics, there is a need for back-end functions and streamlined tools for processing, ... -
An organ deformation model using Bayesian inference to combine population and patient-specific data
(Journal article; Peer reviewed, 2023)Objective. Organ deformation models have the potential to improve delivery and reduce toxicity of radiotherapy, but existing data-driven motion models are based on either patient-specific or population data. We propose to ... -
The Organ Sparing Potential of Different Biological Optimization Strategies in Proton Therapy
(Journal article; Peer reviewed, 2021)Purpose: Variable relative biological effectiveness (RBE) models allow for differences in linear energy transfer (LET), physical dose, and tissue type to be accounted for when quantifying and optimizing the biological ... -
Organelle bottlenecks facilitate evolvability by traversing heteroplasmic fitness valleys
(Journal article; Peer reviewed, 2022)Bioenergetic organelles—mitochondria and plastids—retain their own genomes (mtDNA and ptDNA), and these organelle DNA (oDNA) molecules are vital for eukaryotic life. Like all genomes, oDNA must be able to evolve to suit ... -
Organic carbon and mineral nutrient limitation of oxygen consumption, bacterial growth and efficiency in the Norwegian Sea
(Peer reviewed; Journal article, 2011-01-12)To evaluate the role of bacteria in the transformation of organic matter in subarctic waters, we investigated the effect of mineral nutrients (ammonia and phosphate) and organic carbon (glucose) enrichment on heterotrophic ... -
Organization, transformation, and activation of the melanocortin system in Atlantic salmon
(Doctoral thesis, 2023-11-03)Atlantisk laks (Salmo salar) er en nøkkelart i norsk havbruk. Det trengs imidlertid mer kunnskap og teknologi for å kontinuerlig utvikle mer bærekraftig produksjon, forbedre dyrevelferden og for å øke den økonomiske verdien ... -
Oribatid mites in a changing world
(Doctoral thesis, 2011-12-09)The main scope of this thesis is to illustrate the validity of oribatid mites as tools for palaeoecological reconstructions. Palaeoecology studies the responses of past organisms to past environmental changes. This can be ... -
Oriented self-assembly of anisotropic layered double hydroxides (LDHs) with 2D-on-3D hierarchical structure
(Journal article; Peer reviewed, 2023)Layered double hydroxides (LDHs) have been the subject of increasing research due to their unique 2D or 3D structures and promising applications. However, achieving precise control over their morphology and architecture ... -
