Visualization Hybridization with Spatialization Cues
(Doctoral thesis, 2022-11-24)Visualisering som et verktøy for visuell prosessering av underliggende data har vist seg å være en akseptert og legitim del av den vitenskapelige argumentasjonsprosessen. Mange forskjellige teknikker bidrar til å oppnå ny ... -
On the Parameterized Complexity of the Expected Coverage Problem
(Journal article; Peer reviewed, 2022)The MAXIMUM COVERING LOCATION PROBLEM (MCLP) is a well-studied problem in the field of operations research. Given a network with positive or negative demands on the nodes, a positive integer k, the MCLP seeks to find k ... -
Assumptions, Efficiency and Trust in Non-Interactive Zero-Knowledge Proofs
(Doctoral thesis, 2022-11-04)Vi lever i en digital verden. En betydelig del av livene våre skjer på nettet, og vi bruker internett for stadig flere formål og er avhengig av stadig mer avansert teknologi. Det er derfor viktig å beskytte seg mot ondsinnede ... -
Honeycomb Plots: Visual Enhancements for Hexagonal Maps
(Chapter, 2022)Aggregation through binning is a commonly used technique for visualizing large, dense, and overplotted two-dimensional data sets. However, aggregation can hide nuanced data-distribution features and complicates the display ... -
Gnocis: An integrated system for interactive and reproducible analysis and modelling of cis-regulatory elements in Python 3
(Journal article; Peer reviewed, 2022-09-09)Gene expression is regulated through cis-regulatory elements (CREs), among which are promoters, enhancers, Polycomb/Trithorax Response Elements (PREs), silencers and insulators. Computational prediction of CREs can be ... -
Mathematical modelling of follicular growth and ovarian stimulation
(Journal article; Peer reviewed, 2022)The aim of ovarian stimulation in fertility treatment is to increase the number of large follicles and hence the number of eggs that can be retrieved for in vitro fertilisation (IVF). However, large inter- and intra-individual ... -
Triplicate functions
(Journal article; Peer reviewed, 2022)We define the class of triplicate functions as a generalization of 3-to-1 functions over \(\mathbb {F}_{2^{n}}\) for even values of n. We investigate the properties and behavior of triplicate functions, and of 3-to-1 among ... -
Wirom2.0: An Extensible System for Mission Planning of Heterogeneous Multi-Robot Teams
(Master thesis, 2022-06-01)Robotics software systems are becoming increasingly more complex, which makes the development progressively more challenging. Heterogeneous robots have different requirements, and their actions need different specifications ... -
Ecological Momentary Assessment in Internet-Delivered Psychological Treatments using Wearable Technology
(Master thesis, 2022-06-01)The growing prevalence of mental health problems is a global concern. Current psychological treatments are effective for a wide range of mental health problems. Yet, treatments today fall short with regards to scalability ... -
A workflow-integrated brain tumor segmentation system based on fastai and MONAI
(Master thesis, 2022-06-01)Artificial intelligence (AI) has achieved great results in medical imaging tasks and has the potential to improve the experiences of clinicians and patients in the future, but on the way toward AI integration in medicine, ... -
Towards stronger Lagrangean bounds for stable spanning trees
(Chapter, 2022)Given a graph G=(V,E) and a set C of unordered pairs of edges regarded as being in conflict, a stable spanning tree in G is a set of edges T inducing a spanning tree in G, such that for each {e_i, e_j} in C, at most one ... -
BioSimulators: a central registry of simulation engines and services for recommending specific tools
(Journal article; Peer reviewed, 2022)Computational models have great potential to accelerate bioscience, bioengineering, and medicine. However, it remains challenging to reproduce and reuse simulations, in part, because the numerous formats and methods for ... -
Impacts of Covid-19 on Norwegian salmon exports: A firm-level analysis
(Journal article; Peer reviewed, 2022)A rapidly growing literature investigates how the recent Covid-19 pandemic has affected international seafood trade along multiple dimensions, creating opportunities as well as challenges. This suggests that many of the ... -
From Molecules to the Masses : Visual Exploration, Analysis, and Communication of Human Physiology
(Doctoral thesis, 2022-09-16)Det overordnede målet med denne avhandlingen er tverrfaglig anvendelse av medisinske illustrasjons- og visualiseringsteknikker for å utforske, analysere og formidle aspekter ved fysiologi til publikum med ulik faglig nivå ... -
VR supported self-help treatment for adolescents with psychosis
(Master thesis, 2022-06-01)Psychosis is a severe psychological condition that affects some people, including adolescents. Unfortunately, treating psychosis and psychotic disorders takes a long time. Cognitive Behavioral Therapy (CBT) and CBT for ... -
eQTLs as causal instruments for the reconstruction of hormone linked gene networks
(Journal article; Peer reviewed, 2022)Hormones act within in highly dynamic systems and much of the phenotypic response to variation in hormone levels is mediated by changes in gene expression. The increase in the number and power of large genetic association ... -
Straggler-Resilient Distributed Computing
(Doctoral thesis, 2022-09-09)Utbredelsen av distribuerte datasystemer har økt betydelig de siste årene. Dette skyldes først og fremst at behovet for beregningskraft øker raskere enn hastigheten til en enkelt datamaskin, slik at vi må bruke flere ... -
Scaling Up Medical Visualization : Multi-Modal, Multi-Patient, and Multi-Audience Approaches for Medical Data Exploration, Analysis and Communication
(Doctoral thesis, 2022-09-02)Medisinsk visualisering er en av de mest applikasjonsrettede områdene av visualiseringsforsking. Tett samarbeid med medisinske eksperter er nødvendig for å tolke medisinsk bildedata og lage betydningsfulle visualiseringsteknikker ... -
Notes on Lattice-Based Cryptography
(Doctoral thesis, 2022-09-06)Asymmetrisk kryptering er avhengig av antakelsen om at noen beregningsproblemer er vanskelige å løse. I 1994 viste Peter Shor at de to mest brukte beregningsproblemene, nemlig det diskrete logaritmeproblemet og ... -
Longitudinal visualization for exploratory analysis of multiple sclerosis lesions
(Journal article; Peer reviewed, 2022)In multiple sclerosis (MS), the amount of brain damage, anatomical location, shape, and changes are important aspects that help medical researchers and clinicians to understand the temporal patterns of the disease. Interactive ...
