Object Migration Automata for Non-equal Partitioning Problems with Known Partition Sizes
(IFIP Advances in Information and Communication Technology;627, Peer reviewed; Journal article, 2021)Solving partitioning problems in random environments is a classic and challenging task, and has numerous applications. The existing Object Migration Automaton (OMA) and its proposed enhancements, which include the Pursuit ... -
The object-tool duality in mathematical modelling - a framework to analyze students’ appropriation of Sankey diagrams to model dynamic processes
(Peer reviewed; Journal article, 2020)Students often do not experience the relevance of learning mathematics. This paper reports on an exploratory case study, in which a class of grade 8 students (n=35) was introduced to Sankey diagrams. The aim was to explore ... -
Observation of a class of disturbance in time series expansion for fractional order systems
(Journal article; Peer reviewed, 2014)This paper is concerned with the problem of designing disturbance observer for fractional order systems, of which the disturbance is in time series expansion. The stability of a special observer with the selected nonlinear ... -
Observation of intrinsically bright terrestrial gamma ray flashes from the Mediterranean basin

Observer-based H∞ control design for nonlinear networked control systems with limited information
(Journal article; Peer reviewed, 2013)This paper is concerned with the problem of designing a robust observer-based H∞ controller for discrete-time networked systems with limited information. An improved networked control system model is proposed and the effects ... -
Observer-based robust control for hydraulic velocity control system
(Journal article; Peer reviewed, 2013)This paper investigates the problems of robust stabilization and robust control for the secondary component speed control system with parameters uncertainty and load disturbance. The aim is to enhance the control performance ... -
Observer-based robust control for spacecraft rendezvous with thrust saturation
(Journal article; Peer reviewed, 2014)This paper proposes an observer-based robust guaranteed cost control method for thrust-limited rendezvous in near-circular orbits. Treating the noncircularity of the target orbit as a parametric uncertainty, a linearized ... -
Observer-based robust H∞ control for switched stochastic systems with time-varying delay
(Journal article; Peer reviewed, 2013)This paper investigates the problem of observer-based robust H ∞ control for a class of switched stochastic systems with time-varying delay. Based on the average dwell time method, an exponential stability criterion for ... -
Observer-based sliding mode control for stabilization of a dynamic system with delayed output feedback
(Journal article; Peer reviewed, 2013)This paper considers the sliding mode control problem for a kind of dynamic delay system. First by utilizing Lyapunov stability theory and a linear matrix inequality technique, an observer based on delayed output feedback ... -
Observer-based stabilization of spacecraft rendezvous with variable sampling and sensor nonlinearity
(Journal article; Peer reviewed, 2013)This paper addresses the observer-based control problem of spacecraft rendezvous with nonuniform sampling period. The relative dynamic model is based on the classical Clohessy-Wiltshire equation, and sensor nonlinearity ... -
Observer-Based Stabilization of Stochastic Systems with Limited Communication
(Journal article; Peer reviewed, 2012)This paper studies the problem of observer-based stabilization of stochastic nonlinear systems with limited communication. A communication channel exists between the output of the plant and the input of the dynamic ... -
Ocean-scale connectivity and life cycle reconstruction in a deep-sea fish
(Journal article; Peer reviewed, 2014)As human exploration and harvesting moves to the high seas, ecological understanding of the deep sea has become a priority, especially in those commercially exploited species whose life cycle, habitat use, and demographic ... -
Offshore Wind Power Technology Development and Testing of a Downscaled Pitch Controlled Wind Turbine
(Master thesis, 2015)The energy demand of the world increases day by day, and at the same time people become more aware of the impact fossil energy sources have on the climate. This leads to an increased focus on renewable energy sources, ... -

Oil whip-induced wear in journal bearings
(Journal article; Peer reviewed, 2014)This paper investigates the effect of oil whirl and oil whip in fluid film radial bearings due to possible metallic contact. The degree of metallic contact and thereby wear and tear between rotating shafts and bearing ... -
Ombruk av hulldekker fra eksisterende bygg
(Master thesis, 2023)For a long time, the construction industry has been dominated by a linear mindset in building projects. The contemporary focus on our earth’s climate, has put pressure on the industry in regard to its relation for circular ... -

Omvendt undervisning i matematikk : en studie av elevers oppfatning av undervisningsmetoden
(Master thesis, 2013)Many teachers want to try out different teaching methods to find the one that makes students learn best. In today's society we surround ourselves with technology most of the day and there are several teaching methods that ... -
On abstraction in the OMG hierarchy: systems, models, and descriptions
(Chapter; Peer reviewed, 2022)The Model-Driven Architecture (MDA) uses a metadata hierarchy with several layers that are placed on top of each other. The traditional view is that the layers provide abstractions related to models in languages defined ...
