Dynamic multi-agent dc-bus reconfiguration in modular motor drives with a stacked polyphase bridge converter
(Journal article; Peer reviewed, 2023)A stacked polyphase bridge converter consists of multiple standard, three-phase two-level voltage source inverters connected in series to the same dc voltage source. The authors present a decentralised and dynamic dc-bus ... -
The dynamic nature of self-excited azimuthal modes in annular combustors
(Doctoral theses at NTNU;2021:209, Doctoral thesis, 2021) -
Dynamic networks of psychological symptoms, impairment, substance use, and social support: The evolution of psychopathology among emerging adults
(Peer reviewed; Journal article, 2022)Background Subthreshold/attenuated syndromes are established precursors of full-threshold mood and psychotic disorders. Less is known about the individual symptoms that may precede the development of subthreshold syndromes ... -
Dynamic Obstacle Avoidance for Nonholonomic Vehicles using Collision Cones: Theory and Experiments *
(Chapter, 2023)Obstacle avoidance is a critical part in the control of autonomous vehicles. This paper proposes an obstacle avoidance algorithm based on the computationally advantageous collision cone concept, for unicycles which may be ... -
The dynamic of stepwise migrations of Nepalese high-skilled migrants via the Middle East
(Peer reviewed; Journal article, 2023)This article explores the experiences of Nepalese highly skilled migrants who use temporary migration to the Gulf region as a stepping-stone to further migration to developed countries outside the region. Furthermore, we ... -
Dynamic Optimization and Parameter Estimation used on an Extrusion Press for Aluminium
(Master thesis, 2022)I dag blir aluminium brukt i flere og flere produkter. Noen av disse, som radiatoren i moderne biler, krever veldig presise produksjonsmetoder. Her brukes tynne, hule profiler som varmevekslere, og de produseres ved ... -
Dynamic Optimization of a District Heating System using Model Predictive Control
(Master thesis, 2019)Å styre et fjernvarmenettverk kan være en utfordrende oppgave. Leverandøren må kontinuerlig håndtere varierende forbruk i et stort og komplekst nettverk, hvor varmetapet kan være betydelig. For å kunne produsere optimalt, ... -
Dynamic optimization of control setpoints for an integrated heating and cooling system with thermal energy storages
(Journal article; Peer reviewed, 2019)Energy systems for buildings and neighborhoods are expected to become more complex and flexible. Advanced control strategies are required to exploit the full potential of this flexibility and are especially important for ... -
Dynamic optimization of railway catenary system by turning unwanted lumped-mass into tuned-mass
(Chapter, 2017)The railway catenary is suspended to its supports with droppers, clamps and oth-er fittings. These lumped-masses are made light and small to minimize disturbances. The mass-es cannot be completely removed but can be adjusted ... -
Dynamic Parameter Investigation of a Full Scale Laboratory Overhead Contact Line Section Model
(Master thesis, 2015)In the dynamic parameter investigation of a full scale laboratory section model of a overhead contact line, the effects of tension force and the effect of removing a dropper is of interest. The thesis present the results ... -
Dynamic Performance of High-Speed Railway Overhead Contact Line Interacting With Pantograph Considering Local Dropper Defect
(Peer reviewed; Journal article, 2020)The local dropper defect is the most common fault in the early service stage of the overhead contact line (OCL) system. The plastic deformation and loose of a dropper may cause the variation of the contact line height, ... -
