On the Certificate Revocation Problem in the Maritime Sector
(Peer reviewed; Journal article, 2021)Maritime shipping is currently undergoing rapid digitalization, but with increasing exposure to cyber threats, there is a need to improve the security of the ship communication technology used during operations across ... -
On the cleansing and inspection of GPS ephemeris data 2000–2016
(Chapter, 2017)Archived GPS ephemeris data for years 2000-2016 is investigated by cleansing and precision measures. The goal of this work was twofold: (1) to reveal and remove incorrect ephemeris data so that the cleansed data is as close ... -
On the Contextualization of Event-Activity Mappings
(Journal article; Peer reviewed, 2019)Event log files are used as input to any process mining algorithm. A main assumption of process mining is that each event has been assigned to a distinct process activity already. However, such mapping of events to activities ... -
On the dimension of multivariate spline spaces
(SINTEF Rapport;, Research report, 2013)In this paper, we define the topological structures for an arbitrary axis-aligned box partition of a parametric d-dimensional box-shaped limited domain in R^d. Then we define the d-variate spline space over this partition ... -
On the globally exponentially convergent immersion and invariance speed observer for mechanical systems
(Journal article; Peer reviewed, 2017)In this article we present a reformulation of the invariance and immersion speed observer of Astolfi et al. as applied to mechanical systems with bounded inertia matrices. This is done to explore the possibility of its ... -
On the Stability of Community Tolerance for Aircraft Noise
(Journal article; Peer reviewed, 2017)Although aircraft noise-induced annoyance prevalence rates vary greatly for similar noise exposure levels in different times and places, some suggest that communities have recently reacted more strongly to aircraft noise ... -
On-Line PI Controller tuning Using Closed-Loop Setpoint Response

Onboarding software developers and teams in three globally distributed legacy projects: A multi-case study
(Journal article; Peer reviewed, 2017)Onboarding is the process of supporting new employees regarding their social and performance adjustment to their new job. Software companies have faced challenges with recruitment and onboarding of new team members, and ... -
One-year trial of 12-hour shifts in a non-intensive care unit and an intensive care unit in a public hospital: a qualitative study of 24 nurses’ experiences
(Journal article; Peer reviewed, 2019)Objectives The aim of this study was to provide recommendations to hospital owners and employee unions about developing efficient, sustainable and safe work-hour agreements. Employees at two clinics of a hospital, one a ... -
Online monitoring of aluminium primary production gas composition by use of Fourier-transform infrared spectroscopy
(Journal article; Peer reviewed, 2014)Online monitoring of aluminium primary production raw gas is challenging due to the high concentration of HF in the presence of water. Tunable Diode Laser (TDL) analyzers retrofitted with sapphire optical windows allow for ... -
Ontology-Based Fault Tree Analysis Algorithms in a Fuzzy Environment for Autonomous Ships
(Peer reviewed; Journal article, 2021)This study deals with fault tree analysis algorithms based on an ontology-based approach in a fuzzy environment. We extend fuzzy fault tree analysis by embedding ontology-based fault tree structures. The ontology-based ... -
Ontology-based Use Cases for Design-time and Runtime Composition of Mobile Services
(Chapter, 2009)This paper presents application of ontology-based modelling and reasoning related to the different phases of the lifecycle of mobile services. Ontology-based descriptions complement traditional design-time and runtime ... -
The Open Porous Media Flow Reservoir Simulator
(Peer reviewed; Journal article, 2020)The Open Porous Media (OPM) initiative is a community effort that encourages open innovation and reproducible research for simulation of porous media processes. OPM coordinates collaborative software development, maintains ... -
Operation platform design for modular adaptable ships: Towards the configure-to-order strategy
(Journal article; Peer reviewed, 2018)Modular adaptable ships have received growing attention in recent decades as a promising approach to handling uncertainty in future operating contexts. A modular adaptable ship can be used for multiple purposes by changing ... -
Operational data-driven prediction for failure rates of equipment in safety instrumented systems: A case study from the oil and gas industry
(Journal article; Peer reviewed, 2019)Safety instrumented systems are frequently deployed to reduce the risk associated with industrial activities, such as those in the oil and gas industry. A key requirement for safety-instrumented systems in standards like ... -
