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 ... -
Objectively recorded physical activity and the association with gestational diabetes
(Journal article; Peer reviewed, 2014)The aim of this population-based study was to assess the association between objectively recorded physical activity (PA) in early gestation and gestational diabetes mellitus (GDM) identified at 28 weeks of gestation in ... -
Objectively recorded physical activity in early pregnancy: A multiethnic population-based study
(Journal article, 2014) -
Objectively recorded physical activity in pregnancy and postpartum in a multi-ethnic cohort: association with access to recreational areas in the neighbourhood
(Peer reviewed; Journal article, 2016)Background: Physical activity may reduce the risk of adverse pregnancy outcomes; however, compared to non-pregnant women, a lower proportion of pregnant women meet the physical activity guidelines. Our objectives were to ... -
Obligasjoner med fortrinnsrett : konsekvenser av en ny finansieringskilde for norske banker
(Master thesis, 2013)Obligasjoner med fortrinnsrett (OMF) er et relativt nytt finansieringsalternativ for norske banker. I 2007 ble det innført et nytt lovverk for obligasjonene som skulle bidra til å øke attraktiviteten blant investorer ... -
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 ... -
