Ombygging av en ensylindret dieselmotor til dual-fuel drift på etanol
(Master thesis, 2022-07-04)Denne rapporten beskriver ombyggingsprosessen av en ensylindret dieselmotor til dual-fuel drift på etanol, og videre presenterer resultater fra utførte forsøk med etanol. Rapporten inkluderer et teoretisk nødvendig grunnlag ... -
Lysozyme activity in skin mucus of Atlantic salmon (Salmo salar) fed dietary insect meal
(Master thesis, 2023-01-30)For å kunne produsere nok mat til en voksende verdensbefolkning er man avhengig av å produsere nok bærekraftig fôr til å opprettholde den raske veksten i akvakulturnæringen. Insekter, som har vist seg å være en god ... -
Accelerated Sarcopenia Phenotype in the DJ-1/Park7-Knockout Zebrafish
(Journal article; Peer reviewed, 2024)Age-dependent loss of muscle mass and function is associated with oxidative stress. DJ-1/Park7 acts as an antioxidant through multiple signalling pathways. DJ-1-knockout zebrafish show a decline in swimming performance and ... -
Cuts in Graphs with Matroid Constraints
(Journal article; Peer reviewed, 2024)Vertex (s, t)-Cut and Vertex Multiway Cut are two fundamental graph separation problems in algorithmic graph theory. We study matroidal generalizations of these problems, where in addition to the usual input, we are given ... -
Hybrid k-Clustering: Blending k-Median and k-Center
(Journal article; Peer reviewed, 2024)We propose a novel clustering model encompassing two well-known clustering models: k-center clustering and k-median clustering. In the Hybrid k-Clustering problem, given a set P of points in ℝ^d, an integer k, and a ... -
Longest Cycle above Erdős–Gallai Bound
(Journal article; Peer reviewed, 2024)In 1959, Erdős and Gallai proved that every graph \(G\) with average vertex degree \({\sf ad}(G)\geq 2\) contains a cycle of length at least \({\sf ad}(G)\). We provide an algorithm that for \(k\geq 0\), in time ... -
Simulation and validation of TCM amine plant data from Monoethanolamine (MEA) campaign.

Stability in Graphs with Matroid Constraints
(Journal article; Peer reviewed, 2024)We study the following INDEPENDENT STABLE SET problem. Let G be an undirected graph and ℳ = (V(G), ℐ) be a matroid whose elements are the vertices of G. For an integer k ≥ 1, the task is to decide whether G contains a set ... -
Computing Tree Decompositions with Small Independence Number
(Journal article; Peer reviewed, 2024)The independence number of a tree decomposition is the maximum of the independence numbers of the subgraphs induced by its bags. The tree-independence number of a graph is the minimum independence number of a tree decomposition ... -
Mixed-Dimensional Approach for Compositional Multiphase Flow in High-Enthalpy Fractured Geothermal Reservoirs
(Stanford Geothermal Workshop;, Chapter, 2025)We present a novel multiphase compositional model for geothermal reservoir simulation that incorporates phase separation phenomena and explicitly represents fractures. Mass and heat transfer in porous media typically use ... -
Breaking a Graph into Connected Components with Small Dominating Sets
(Journal article; Peer reviewed, 2024)We study DOMINATED CLUSTER DELETION. Therein, we are given an undirected graph G = (V,E) and integers k and d and the task is to find a set of at most k vertices such that removing these vertices results in a graph in which ... -
Temperature sensitivity of the mineral permafrost feedback at the continental scale
(Journal article; Peer reviewed, 2024)Oxidative weathering of sulfide minerals in sedimentary rocks releases carbon dioxide (CO2) into the atmosphere. In permafrost zones, this could be a positive feedback on climate change if it increases with warming, yet ... -
Impact of MRI radiomic feature normalization for prognostic modelling in uterine endometrial and cervical cancers
(Journal article; Peer reviewed, 2024)Widespread clinical use of MRI radiomic tumor profiling for prognostication and treatment planning in cancers faces major obstacles due to limitations in standardization of radiomic features. The purpose of the current ... -
Overweight and obesity as risk factors for chronic low back pain: a new follow-up in the HUNT Study
(Journal article; Peer reviewed, 2024)Background Numerous studies have examined associations between overweight and obesity and risk of low back pain (LBP), but the exact magnitude of these associations is not yet clear. The purpose of this work was to ... -
Measurement of the fraction of jet longitudinal momentum carried by Λc+ baryons in pp collisions

Fixed-Parameter Tractability of Maximum Colored Path and beyond
(Journal article; Peer reviewed, 2024)We introduce a general method for obtaining fixed-parameter algorithms for problems about finding paths in undirected graphs, where the length of the path could be unbounded in the parameter. The first application of our ... -
Differential regulation of magnesium transporters Slc41, Cnnm and Trpm6-7 in the kidney of salmonids may represent evolutionary adaptations to high salinity environments
(Journal article; Peer reviewed, 2024-11-29)Magnesium is important for enzymatic reactions and physiological functions, and its intracellular concentration is tightly regulated. Atlantic salmon has the ability to handle large changes in environmental Mg2+ concentration ... -
Hydrography and circulation below Fimbulisen Ice Shelf, East Antarctica, from 14 years of moored observations
(Journal article; Peer reviewed, 2024)Future mass loss from the East Antarctic Ice Sheet represents a major uncertainty in projections of future sea level rise. Recent studies have highlighted the potential vulnerability of the East Antarctic Ice Sheet to ... -
A Simple Statistical Postprocessing Scheme for Enhancing the Skill of Seasonal SST Predictions in the Tropics
(Journal article; Peer reviewed, 2024)Seasonal prediction systems are subject to systematic errors, including those introduced during the initialization procedure, that may degrade the forecast skill. Here we use a novel statistical postprocessing correction ... -
MAP- and MLE-Based Teaching
(Journal article; Peer reviewed, 2024)Imagine a learner L who tries to infer a hidden concept from a collection of observations. Building on the work of Ferri et al. (2022), we assume the learner to be parameterized by priors P (c) and by c-conditional likelihoods ...
