Dynamic modelling of national dwelling stocks: Understanding phenomena of historical observed energy demand and future estimated energy savings in the Norwegian dwelling stock
(Doctoral theses at NTNU;2017:36, Doctoral thesis, 2017)Residential buildings are responsible for 24% of the global final energy consumption, and the housing sector is important for future mitigation of greenhouse gases. Scenario models are important tools for estimation of the ... -
Dynamic modelling of the thermal response enhanced by sloshing in marine LNG fuel tanks
(Journal article; Peer reviewed, 2018)This paper investigates the thermal response in marine liquefied natural gas (LNG) fuel tanks by experiments and modelling. The aim of this work is to develop phenomenological models that can predict the rapid pressure ... -
Dynamic Modelling of Twin Harmonic Counter-Rotating PMSM for Booster Pump in Pumped Storage Hydropower
(Master thesis, 2023)En prototype av en permanentmagnet synkronmotor med utpregede poler og doble rotorer har blitt grundig simulert gjennom endelig elementanalyse i COMSOL. De to rotorene utnytter positiv og negativ sekvens harmoniske komponenter ... -
Dynamic Modelling, Simulation and Visualization of Marine Crane Operations on DP Vessels
(Master thesis, 2015)The research presented in this thesis is based on the idea that to find a better method of modelling, simulation and controlling the dynamic mechanical systems by using Lagrange method and bond graph approach. Based on the ... -
Dynamic Modelling, Vibration and Fatigue Analysis of Slow Rotating Propulsion Systems
(Master thesis, 2018)In recent years, shipping has experienced a technical transformation motivated by its impact on the environment and the desire to reduce operational costs. Engines with lower power ranges and slow steaming are two examples. ... -
Dynamic Models of Fixed Capital Stocks and Their Application in Industrial Ecology
(Journal article; Peer reviewed, 2014)Industrial assets or fixed capital stocks are at the core of the transition to a low-carbon economy. They represent substantial accumulations of capital, bulk materials, and critical metals. Their lifetime determines the ... -
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 ... -

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
